10948 check-ins using file ext/misc/totype.c version 4a167594

2024-04-02
18:48
Fix typos in comments. Provided ".wheretrace" debugging output for the interstage heuristic module. Do omit automatic index loops in the interstage heuristic. (Leaf check-in: 357d9513 user: drh tags: branch-3.28)
18:31
Fix table-valued functions so that they will work as the right table in a LEFT JOIN. Ticket [2ae0c599b735d59e] (check-in: 1f97086d user: drh tags: branch-3.28)
11:54
Add a heuristic in between the two solver() passes of the query planner that tries to prevent a very slow query plan in cases where the output row count estimate is imprecise. (check-in: 74b247d9 user: drh tags: branch-3.28)
2023-11-29
16:26
Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (check-in: f10d4fc4 user: drh tags: branch-3.28)
16:07
Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a7 user: drh tags: branch-3.28)
2023-10-19
21:05
Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28)
2023-09-15
20:04
Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28)
2023-02-26
11:52
In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e user: drh tags: branch-3.28)
2023-02-16
21:01
Fix an #ifdef that uses a different macro name from the main branch. (check-in: ad6ac5d3 user: drh tags: branch-3.28)
19:04
Back-port omit-unused-subquery-column enhancements into the 3.28 branch. (check-in: 57a4e91f user: drh tags: branch-3.28)
14:29
Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 0163b697 user: drh tags: branch-3.28)
01:29
Do not compute unused result columns of subqueries. This optimization will potentially resolve the performance optimization request of [ticket baa5bb76c35a124c]. (Closed-Leaf check-in: 0c21b6a5 user: drh tags: branch-3.26)
01:21
Update test cases so that they work with TCL 8.7 and later. (check-in: e9b762de user: drh tags: branch-3.26)
2023-02-15
13:00
Update the configure script so that it contains the correct version number. (check-in: a7cbf308 user: drh tags: branch-3.26)
2022-10-24
13:50
Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de user: drh tags: branch-3.28)
2022-10-19
11:22
If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)
2022-09-27
17:00
Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14)
2022-09-01
10:41
In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)
2022-08-10
17:03
Merge the branch-3.28a fixes into branch-3.28. (check-in: ba6bf331 user: drh tags: branch-3.28)

18:44
If the special "sqlite_rbu_replace_hack" table is present in an RBU database, use REPLACE instead of INSERT when writing index entries to imposter tables. (check-in: 4b73e151 user: dan tags: rbu-replace-hack)
2021-07-13
15:30
Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. This allows the SQL associated with CVE-2020-13871 (ticket [c8d3b9f0a750a529]) to be tested. (Closed-Leaf check-in: d2e67220 user: dan tags: branch-3.28a)
2021-07-12
14:38
Fix a defect in the query-flattener optimization identified by ticket [8f157e8010b22af0]. This fix is associated with CVE-2020-15358. (check-in: 9e001b63 user: dan tags: branch-3.28a)
2020-10-22
18:58
Minor tweaks to query planning weights so that when STAT4 is enabled and functioning, a full table scan is more likely to be selected if that seems like the fastest solution. Only do this when STAT4 info is available because an error has a large potential downside. (check-in: 263293f1 user: drh tags: branch-3.28)
2020-10-02
13:57
Import further corner-case fixes for the in-scan-vs-index or OP_SeekScan optimization from trunk. (check-in: c144d640 user: drh tags: branch-3.28)
12:11
For the OP_SeekScan optimization, the OP_IdxGT does not necessarily come right after the OP_SeekGE. So use the P2 operand of OP_SeekScan to point to the first instruction after OP_IdxGT. Problem found by dbsqlfuzz. (check-in: ec37744c user: drh tags: branch-3.28)
02:07
Disable the OP_SeekScan opcode of the in-scan-vs-index optimization when in PRAGMA reverse_unordered_selects mode, as the OP_SeekScan only works with forwards scans. Thanks to OSSFuzz for pointing out the problem to us. (check-in: 9a1cdf7e user: drh tags: branch-3.28)
2020-09-30
18:22
Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: f07ac3fb user: drh tags: branch-3.28)
2020-09-01
02:02
Improvements to the IN-early-out optimization so that it works more efficiently when there are two or more indexed IN clauses on a single table. (check-in: 49b7631e user: drh tags: branch-3.28)
2020-08-31
19:19
An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. Update: Experiment did not work out. (Closed-Leaf check-in: 8301da31 user: drh tags: branch-3.28-in-early-out-fail)
2020-08-17
21:03
When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. (check-in: 0ecda433 user: dan tags: branch-3.28)
2020-05-06
18:46
Provide the SQLITE_DEFAULT_LEGACY_ALTER_TABLE compile-time option. (check-in: b2325a6e user: drh tags: branch-3.28)
2020-01-17
15:33

15:24
Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 3d13fbf2 user: drh tags: branch-3.28)
14:56
Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f user: drh tags: branch-3.28)
14:30
Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c6 user: drh tags: branch-3.28)
14:18
Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22)
2019-12-19
03:14
More restrictions on changes to shadow tables when in defensive mode. (Leaf check-in: 4146c629 user: drh tags: branch-3.30)

2019-10-30
16:29
Simplify the bytecode generation for SQL function calls such that the OP_Function or OP_PureFunc opcodes are coded directly, rather than using the intermediate OP_Function0 or OP_PureFunc0 - opcodes that are now removed. (check-in: 84e02d77 user: drh tags: trunk)
13:00
New tokens ALWAYS, GENERATED, and STORED used by generated columns should all be fallback tokens. (check-in: 13fe6978 user: drh tags: trunk)
2019-10-29
16:18
Remove the legacy_file_format PRAGMA. In its place, provide the SQLITE_DBCONFIG_LEGACY_FILE_FORMAT option to sqlite3_db_config(). Fix for ticket [6484e6ce678fffab] (check-in: 4d424f30 user: drh tags: trunk)
03:39

2019-10-26
23:51
Remove code from the constraint checker that generates virtual column values with the incorrect time. Turns out the the regular code for all other columns works correctly and so the incorrect special-case code is not actually needed. Fix for ticket [3ea175512444b0d1]. (check-in: 5b4c0f2d user: drh tags: trunk)
18:56
Remove redundant code resulting from a merge error on the previous check-in. (check-in: 713fe86b user: drh tags: trunk)
18:47
Add support for generated columns. (check-in: b855acf1 user: drh tags: trunk)
17:08
Performance optimization on sqlite3GenerateConstraintChecks() - bypass the loop that checks each column for NOT NULL constraints if it is known in advance that the table has no NOT NULL constraints. (check-in: e3c3f4d7 user: drh tags: trunk)
16:38
Clarify some comments and add assert() and testcase() macros to the replace-trigger recheck logic for ticket [c1e19e12046d23fe] (check-in: 8c0042bd user: drh tags: trunk)

12:27
Overnight, OSSFuzz helpfully pointed out a potential use-after-free bug in yesterdays changes, involving continued use of a pointer after the memory pointed to had been realloc()-ed. Thanks Google. (check-in: c422afb5 user: drh tags: trunk)
01:43
Add missing VdbeCoverage() macro. Fix an off-by-one error in partial index handling. New test cases. Ticket [c1e19e12046d23fe] (check-in: 41cc8e3d user: drh tags: trunk)
00:04
If replace triggers are run during uniqueness checking, then rerun all uniqueness checks a second time using the ABORT algorithm. Fix for ticket [c1e19e12046d23fe] (check-in: fbac0c65 user: drh tags: trunk)
2019-10-25

20:35
In fts5, fix a case of overreading a buffer by 1 byte when counting characters in malformed utf-8. Fix for [dd1f67bf]. (check-in: 8d964e1c user: dan tags: trunk)

Move the sqlite3LocateCollSeq(), sqlite3FindCollSeq(), and sqlite3GetCollSeq() routines so that they are all beside one another in the callback.c source file. No logic changes. (check-in: 9ff80a9b user: drh tags: trunk)
00:03
When flipping ("commuting") a comparison operator, set the new EP_Commuted bit rather than adding extra EP_Collate bits, to single later processing that the order of precedence for COLLATE operators is inverted. Fix for ticket [b47e3627ecaadbde] (check-in: 90f7c477 user: drh tags: trunk)
2019-10-21

15:58
Enhance the ".imposter" command in the CLI so that the first argument can be an existing WITHOUT ROWID table instead of an index. The resulting imposter is the same table, but with columns in storage order and with all constraints removed. (check-in: 9dc0d345 user: drh tags: trunk)
12:52
Claw back some performance from the sqlite3ExprGetColumnOfTable() routine. (check-in: e8426acb user: drh tags: generated-columns)

2019-10-17
18:35
In the Table object, change the nVCol field to nNVCol - the number of non-virtual columns, as that is the quantity that we need most. (check-in: 4ad66af0 user: drh tags: generated-columns)

Basic UPDATE functionality working for VIRTUAL columns. (check-in: c21959d4 user: drh tags: generated-columns)
15:41
Avoid an infinite loop in fts3/4 incremental-merge in the case where the lowest level in the database contains segments but no data (because there is a delete-marker for each valid entry). Fix for [bf1aab89]. (check-in: 35beaee0 user: dan tags: trunk)
14:21
Bug fixes so that "make test" once against runs with no errors. (check-in: 7bfe0f67 user: drh tags: generated-columns)
13:15
Fix the table_info and table_xinfo pragmas so that they work with virtual columns. Table_info omits virtual columns. Table_xinfo gives them a "hidden" flag of 2, and 3 for STORED columns. (check-in: 069351b8 user: drh tags: generated-columns)
2019-10-16
22:01

Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. (check-in: 7f5168a7 user: drh tags: trunk)

13:32
Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. (check-in: bf875e1a user: drh tags: nulls-last)

Fix the sqliteExprImpliesExpr() routine so that it recognizes that "(NULL IS FALSE) IS FALSE" doe not imply "NULL NOT NULL". Ticket [9080b6227fabb466] (check-in: da01ba4f user: drh tags: trunk)
14:35
Add extra test cases related to the previous commit. (check-in: 3c690b2b user: dan tags: trunk)

Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. (check-in: f1cd234c user: drh tags: trunk)
18:49
Fix a case of the Expr.affinity to Expr.affExpr refactor that was missed in the [a29f2a7d07beff64] check-in. (check-in: 83450d10 user: drh tags: trunk)
16:23
More legacy STAT3 code removed. (Closed-Leaf check-in: 845d2f17 user: drh tags: omit-stat3)
15:47
Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. (check-in: edf45cd7 user: dan tags: reuse-schema)
15:24
Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: 1e17ea2f user: drh tags: omit-stat3)
11:44
Fix a bug causing "no such table" and other similar sqlite3_prepare*() errors to return SQLITE_SCHEMA instead of SQLITE_ERROR in shared-schema mode when there is an attached database for which the schema has never been loaded. (check-in: 111e2c73 user: dan tags: reuse-schema)

Remove use of the affinity() function from view.test, as it is only available in SQLITE_DEBUG builds. (check-in: 7f2246a1 user: dan tags: trunk)
18:34
Add "set TMP=%CD%" to the start of each msvc script output by releasetest_data.tcl. Otherwise, since binaries compiled with SQLITE_TEST all choose the same sequence of pseudo-random numbers, collisions between temp file names cause errors when running multiple tests in parallel. (check-in: f5d0436d user: dan tags: trunk)
17:45
Eliminate some more cases of redundant sorting in window-function queries. (check-in: 8158d2ac user: dan tags: trunk)
13:25
Do not make SQLITE_READ authorizer calls for tables without names, as all such tables will be internal-use-only tables for subqueries and whatnot. (check-in: 193c87fc user: drh tags: trunk)
2019-08-06

Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. (check-in: 17b3d221 user: dan tags: trunk)

Add a multi-threaded test to threadtest3.c for the feature on this branch. (check-in: 62557fab user: dan tags: reuse-schema)
14:37
Use 0x40 (ASCII '@') instead of 0x00 to mean "no affinity" so that columns with no affinity can appear in a zero-terminated string. Use the new SQLITE_AFF_NONE macro for this new magic number. (check-in: e8234f69 user: drh tags: pending)

Ensure that columns of views and sub-queries that are expressions with no affinity are not assigned BLOB affinity. This matches the documentation. Fix for [61c853857f40da49]. (On a branch because there are still subtle issues.) (check-in: e15a0977 user: dan tags: pending)

Fix the patch on this branch so that it works with sub-queries, as well as views. (check-in: 7480db30 user: dan tags: tkt-61c853-A)
19:34
The second option for [61c853857f40da49]: In this mode, columns of VIEWs and subqueries that are formed by expressions have affinity BLOB rather than affinity none, as has usually been the case for a while. But this mode fixes a couple of corner cases involving query flattening and the push-down optimization where that rule was violated. (Closed-Leaf check-in: 470ac8d5 user: drh tags: tkt-61c853-B)
19:32
One of two options on how to address ticket [61c853857f40da49]. In this mode, we back out the documentation change of [07b7749da88d54e5] and change the core to work as it has been documented to work since 2017, rather than how it has actually worked since 2009. (check-in: 09cd0c0c user: drh tags: tkt-61c853-A)

Refactor field Expr.affinity into Expr.affExpr to avoid confusion with other fields and variables named "affinity" and display affExpr it in sqlite3TreeViewExpr() output. (check-in: a29f2a7d user: drh tags: trunk)

Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. (check-in: 2660e929 user: drh tags: trunk)
01:39
Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. (Closed-Leaf check-in: 49aa3448 user: drh tags: prng-seed-test-control)

The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. (check-in: 961e2f08 user: drh tags: trunk)

14:22
Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. (check-in: 89bf0399 user: drh tags: trunk)

18:35
A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the logic a little easier to follow. Also disallows the use of the double-quoted string hack in the query expression used for VACUUM INTO, which is not strictly required, but moves us toward the goal of disallowing the double-quoted string hack everywhere. (check-in: 3e1b55f3 user: drh tags: trunk)
17:14
Disallow string constants enclosed in double-quotes within new CREATE TABLE and CREATE INDEX statements.

19:34
Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. (check-in: 3a16ddf9 user: drh tags: trunk)

2019-05-02
21:36
Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions.

20:56
Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around.

17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization.

00:56
Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. (check-in: f7ba2daf user: drh tags: trunk)

21:56
In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. (check-in: e775ef00 user: drh tags: trunk)
21:55
Remove a test from the index build logic which is no longer needed and is in fact unreachable. (check-in: 9b20ee10 user: drh tags: trunk)
21:35
Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. (check-in: 24ef3844 user: drh tags: trunk)
19:50
Earlier detection of corruption while added to the freelist. (check-in: 8c80b004 user: drh tags: trunk)
18:44
Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. (check-in: bcbe7d96 user: drh tags: trunk)
15:09
Improvements to the help text in the CLI. (check-in: 919fec91 user: drh tags: trunk)
15:06
Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. (check-in: f11c8959 user: drh tags: trunk)
14:24
For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. (check-in: 191a023a user: drh tags: trunk)

13:53
We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). (check-in: 7a0a26ed user: drh tags: trunk)

2019-03-20
20:27
Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. (Leaf check-in: 9ef69d18 user: drh tags: apply-affinity-first)

15:36
When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. (check-in: a420ebd0 user: drh tags: trunk)
11:56
Revert the OP_MustBeInt opcode implementation on this branch so that it again matches trunk. The extra functionality is no longer required. (check-in: c02f77b1 user: dan tags: window-functions)
11:35
Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. (check-in: a026189a user: dan tags: trunk)

Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. (check-in: 0d456456 user: drh tags: tkt-df46dfb631)
19:24
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. (check-in: 579b66ea user: dan tags: trunk)
17:44
Merge latest trunk changes into this branch. (check-in: 001771af user: dan tags: reuse-schema)

In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. (check-in: 73056b31 user: drh tags: trunk)
15:42
Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. (check-in: e7144ffd user: drh tags: trunk)
2019-02-21
18:11
Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c user: dan tags: nested-parse-oom)
16:41
Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d5639 user: drh tags: trunk)

Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042 user: dan tags: reuse-schema)

Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. (check-in: c48f6f39 user: drh tags: trunk)
17:36
Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. (check-in: 9a78d89c user: dan tags: reuse-schema)
13:55
Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. (check-in: 0c5db18d user: drh tags: trunk)
13:23
Merge the latest performance enhancements and fixes from trunk. (check-in: be71d1e2 user: drh tags: apple-osx)

Increment the version number to 3.27.2. (check-in: a70d67d8 user: drh tags: branch-3.27)
13:12
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. (check-in: 55e38d53 user: drh tags: branch-3.27)
12:52
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. (check-in: fa792714 user: drh tags: trunk)
03:38
Back off the optimization of check-in [e130319317e76119] slightly so that it only applies to IN operators that are used for membership tests. Proposed fix for ticket [df46dfb631f75694]. (Closed-Leaf check-in: b5f90bfe user: drh tags: tkt-df46dfb631)

18:00
Improve error messages caused by corrupt database schemas in OPEN_SHARED_SCHEMA mode. (check-in: 8ac75b8a user: dan tags: reuse-schema)
17:45
Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. (check-in: 12517d1b user: drh tags: trunk)
16:42
Fix an assert() that might not be true if the database file is corrupt. (check-in: f2d400db user: drh tags: trunk)

Enhance the virtual table in test_schemapool.c so that it can be used to check that SHARED_SCHEMA connections are not allocating and freeing schemas when they should not be. (check-in: cb236cb9 user: dan tags: reuse-schema)
19:00
Fix a problem with eponymous virtual tables and SHARED_SCHEMA databases. Also, after preparing statements that require all database schemas (REINDEX, ANALYZE, CREATE, DROP and some PRAGMA statements), do not allow the database connection to return more than one schema to each schema-pool. (check-in: ecf6251e user: dan tags: reuse-schema)
11:54
Revert the rearrangement of VDBE code in [219b39e14] so that vdbe.c matches trunk. Since the new call to sqlite3Init() in OP_ParseSchema was removed, the rearrangement no longer provides any performance advantage. (check-in: 03c4f003 user: dan tags: reuse-schema)

Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. (check-in: 167b91df user: drh tags: trunk)
21:04
Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. (check-in: 68cce272 user: drh tags: trunk)
20:58
Add tests for creating temp schema objects with SQLITE_OPEN_REUSE_SCHEMA connections. (check-in: 8c07b609 user: dan tags: reuse-schema)

Fix a page-cache reference leak in the btree balancer when there is a corrupt database. (check-in: 92858991 user: drh tags: deferred-free-space)
21:06
Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. (check-in: 1d43ee40 user: drh tags: deferred-free-space)

Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d212957 user: drh tags: trunk)
15:59
Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. (check-in: 5c499da8 user: drh tags: trunk)
14:59
Merge the fix for ticket [4e8e4857d32d401f], so that this branch now contains release 3.27.1 plus the extra patch to preserve ROWID values on VACUUM. (check-in: 0cdae60e user: drh tags: apple-osx)
14:55
Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. (check-in: 5c663804 user: drh tags: trunk)
13:17
Version 3.27.1 (check-in: 0eca3dd3 user: drh tags: release, branch-3.27, version-3.27.1)

Increase the version number to 3.27.1. (check-in: b94d5428 user: drh tags: branch-3.27)
04:15
Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. (check-in: 440a7cda user: drh tags: trunk)

01:18
When extending the size of SrcList objects, do not attempt to use extra space on the end of the allocation, as that provides scarcely any performance benefit but does greatly complicate cross-platform testing. (check-in: 3087a0c3 user: drh tags: trunk)
00:55
If the query flattener detects an error, cause the SELECT code generator to abort immediately. (check-in: 3d3b142f user: drh tags: trunk)
00:11
Back out check-in [008112bcef561a8], reenabling deprecated PRAGMAs when the SQLITE_OMIT_DEPRECATED compile-time option is used, because way too many TH3 tests depend on those deprecated PRAGMAs. (check-in: 9dbf512d user: drh tags: trunk)
2019-02-05
20:51
Omit the ".progress" command from the shell if it is compiled with the SQLITE_OMIT_PROGRESS_CALLBACK option. (check-in: 4d0a949f user: drh tags: trunk)

Mention the new -memtrace command-line option in the -help output of the CLI. (check-in: ada91aef user: drh tags: trunk)
19:50
Add the -memtrace option to dbfuzz2. (check-in: 67fecbc7 user: drh tags: trunk)

Enhance dbfuzz2 so that with the -v option it shows the return code and error message for any failing SQL statements. (check-in: 3a127ef9 user: drh tags: trunk)
19:12
Ensure that the sqlite3_exec() callback gets the correct number of columns for a query, even if the schema changes out from under it. (check-in: a16ffb5a user: drh tags: trunk)

Try new approach ensuring that each Schema object is only used by one connection/database at any one time. (check-in: 9e8e5f52 user: dan tags: reuse-schema)
18:24
New testcase added to test/fuzzdata8.db. (check-in: 2f5c1925 user: drh tags: trunk)

Give a link to the URI Filename document in the documentation to the various sqlite3_uri_parameter() interfaces. (check-in: 69b0b2ee user: drh tags: trunk)
13:47
Fix a buffer overread in fts5 debugging scalar function fts5_decode(). (check-in: 54f2399f user: dan tags: trunk)

Fix harmless compiler warning. (check-in: dddda685 user: mistachkin tags: trunk)
2019-02-01
21:08
Slight adjustment to the printf formatter large memory allocation detector so that it does not overestimate the amount of space needed for oversize %d conversions. (check-in: 1aee70d6 user: drh tags: trunk)
20:29
Prevent the printf formatter from doing large memory allocations - larger than either the size of the static buffer for interfaces like sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that are associated with a database connection. This helps to prevent DOS attacks on products that let hostile sources inject arbitrary SQL. It also helps fuzzers run faster and more effectively. (check-in: 179e5d46 user: drh tags: trunk)
18:46
Performance improvement in the parsing of options to %-formats in the printf implementation. (check-in: 40d8f8ae user: drh tags: trunk)

Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c].

Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199 user: drh tags: trunk)
02:26
A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac user: drh tags: trunk)

13:18
When saving the position of a cursor at the b-tree layer, allocate a few extra bytes at the end of the buffer used to save the key. Otherwise, if the key is corrupt, the code that restores the cursor position may overread the buffer by a little. (check-in: 160b1e31 user: dan tags: trunk)

Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions.

Update the changesetfuzz program to fuzz changeset schemas as well as data. (check-in: 141a93c8 user: dan tags: changesetfuzz)
19:26
Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. (check-in: a1d6c671 user: drh tags: read-only-shadow)

Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. (check-in: d890c658 user: drh tags: read-only-shadow)
13:37
Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). (check-in: f79b47c9 user: drh tags: read-only-shadow)
2018-11-05
23:01
Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder.

On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file.

12:37
Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. (check-in: 903e5018 user: drh tags: trunk)
10:47
Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. (check-in: 3dd35f51 user: drh tags: trunk)

Comment typo fixed. No code changes. (check-in: 7e68cdab user: drh tags: trunk)
18:43
Put a limit counter on the query planner that restricts the number of index+constraint options that can be considered for each table in a join. This prevents certain pathological queries from taking up too much time in the query planner. (check-in: 8690b5a0 user: drh tags: trunk)
13:07
Optimization to the OP_MakeRecord opcode makes speed-check.sh run about 1.1 million cycles faster, and results in a slightly smaller library. (check-in: d10e6362 user: drh tags: trunk)

20:43
Minor code simplification. (check-in: 22ae8a52 user: drh tags: trunk)
20:15
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. (check-in: 7edd26ed user: drh tags: trunk)
19:02
Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. (check-in: ad130bb8 user: drh tags: trunk)
17:21
By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. (Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table)

Add a PRAGMA that restores the legacy ALTER TABLE RENAME TO behaviour. (check-in: 5acad2e9 user: dan tags: legacy-alter-table)
2018-09-19
20:14
Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... (Leaf check-in: 24b0f66a user: drh tags: expr-simplify)
18:17
A minor code simplification, saved in a branch for future reference. (Leaf check-in: 5e458f4a user: drh tags: minor-altertab-simplification)

14:54
Reduce the size of Expr from 80 to 72 bytes moving the pRight field inside the "x" union. This is an incremental check-in that still has issues. (check-in: 147c61a6 user: drh tags: expr-simplify)
11:59
Make sure temporary Expr objects are fully initialized prior to sending them into sqlite3ExprCodeTemp(). (check-in: de02a1d9 user: drh tags: expr-simplify)
2018-09-18
21:35
In the Expr object, the Expr.eX field determines what value is stored in the Expr.x union. This mostly works, but there are issues identified by valgrind. (check-in: 8849a463 user: drh tags: expr-simplify)

17:00
Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. (check-in: de2e3cbd user: dan tags: trunk)
16:06
Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. (check-in: 3e1a2f66 user: dan tags: trunk)

Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7 user: drh tags: trunk)

Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization.

Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. (check-in: 3f5f60cd user: drh tags: omit-column-cache)

Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. (check-in: fa94b49e user: drh tags: trunk)

16:57
Constant propagation is now restricted to just the WHERE clause. The mechanism is changed to take affinity and collation into account. This seems to give correct answers. But the search for constant propagation costs 4 million cycles in the speed test. (check-in: 82c67efb user: drh tags: propagate-const-opt)

Add a test case demonstrating the collation problem with constant propagation. (check-in: 50add839 user: drh tags: propagate-const-opt)
23:47
Generalize the constant propagation optimization so that it applies on every WHERE close, not just those that contain a subquery. This then demonstrates that the current implementation is inadequate since it does not take into account collating sequences. (check-in: 57eb2abd user: drh tags: propagate-const-opt)

Change the SQLITE_Stat34 bit of the optimization test-control so that it prevents STAT4 data from being used but allows it to be loaded into the Index objects. This permits STAT4 to be turned on and off on a per-statement basis. (check-in: 489f3caf user: drh tags: trunk)
18:01
Experimental change to ANALYZE so that when computing values for sqlite_stat1, it uses the maximum number for the number of rows having equivalent values, rather than the average. (Leaf check-in: 085f17e1 user: drh tags: stat1-max)

16:04
Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). (check-in: cd2da7e1 user: drh tags: trunk)
15:55
Experimental planner change to avoid a skip-scan if a regular index scan on the same index columns can be done instead. (Leaf check-in: 350f29ea user: dan tags: exp-begin-concurrent-pnu)

02:02
During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails due to an authorizer denying the INSERT into the sqlite_master table, then detect this fact and abort the CREATE TABLE early, to avoid an assertion fault. (check-in: 164b1641 user: drh tags: trunk)
2018-07-08
01:02
Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method. This allows xStep method pointer to be replaced with a single noopStepFunc() procedure, and thus save having lots of different no-op step functions. (check-in: 410e13b0 user: drh tags: trunk)

16:49
Slightly smaller and faster code by encapsulating wal-index hash table location information in a separate WalHashLoc object rather than passing around the various elements as separate variables. (check-in: 538a365b user: drh tags: trunk)

Avoid invoking the whereLoopAddOr() routine in the query planner if there are no OR operators in the WHERE clause, thus speeding up query planning slightly. (check-in: 292724ff user: drh tags: trunk)
2018-06-08
23:23
When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf user: drh tags: trunk)
21:21
Only choose to scan an IN operator rather than use an index if we have real STAT1 data to suggest it is advantageous. (Closed-Leaf check-in: 30e87466 user: drh tags: in-scan-vs-index)

18:22
Consider doing a partial table scan to fulfill an IN operator rather than using an index. Try to pick the plan with the lowest cost. (check-in: 1fa40a78 user: drh tags: in-scan-vs-index)

Add window functions lag() and lead(). (check-in: ef342070 user: dan tags: exp-window-functions)
18:13
The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value. (check-in: 09fffbdf user: drh tags: trunk)

Change sqlite3BtreeBeginTrans() to return the BTREE_SCHEMA_COOKIE, for a small speed improvement when starting new transactions. (check-in: a10662aa user: drh tags: trunk)
01:18
Fix the ".archive" command in the CLI (and the corresponding -A command-line option) so that it silently ignores filenames that contain "../" in their names. This prevents the "Zip Slip" attack. (check-in: 27291f2d user: drh tags: trunk)
00:36
Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference. (Closed-Leaf check-in: bad4d7a0 user: drh tags: dead-end)

Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause. (check-in: e15e1006 user: drh tags: trunk)
20:45
Add the OP_IfNoHope and OP_SeekHit opcodes used to reduce the number of unnecessary sqlite3BtreeMovetoUnpacked() calls when checking for an early exit on IN-operator loops. Futher optimizations are likely possible here. (check-in: 6bf251af user: drh tags: multikey-opt-idea)
20:04
Calculate non-aggregate expressions in the SELECT list of an aggregate query that does not use min() or max() once per group, instead of once per row visited. (Closed-Leaf check-in: dce2dfbe user: dan tags: exp-agg-opt)
16:16
Add implementation of last_value() window function. (check-in: 2493ce1a user: dan tags: exp-window-functions)
15:16
Use an OP_NotFound opcode to cancel futile IN operators early. The current implementation is suboptimal because it always runs teh OP_NotFound. This still needs to be enhanced to only do the OP_NotFound if no results have been seen on the current loop. (check-in: 87a9fc50 user: drh tags: multikey-opt-idea)
13:54
Merge trunk changes. (check-in: 047295c5 user: drh tags: multikey-opt-idea)

11:31
Ensure that sqlite3AuthRead() is only call for TK_COLUMN and TK_TRIGGER expression nodes. This fixes a harmless assert() identified by OSSFuzz. Move the assert() into a position where it is tested even if the authorizer is disabled. (check-in: d0c3beef user: drh tags: trunk)
2018-06-01
21:00
Allow an entire partition to be cached in a temp table for all types of window frames. This is required by nth_value() and others. (check-in: b5b18f66 user: dan tags: exp-window-functions)

Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes. If the OP_Noop generated where were really a new opcode that checked to see if there existed any entries in the index with a matching prefix, it might prevent unnecessary iterations of the IN operator.

Increase the number of database handles opened by test script oserror.test to provoke an "out of file-descriptors" error to 20000 (from 2000). (check-in: 3b00f734 user: dan tags: trunk)

Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. (Leaf check-in: a353b1d7 user: drh tags: vtab-func-constraint)
16:00
Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. (check-in: 777189ce user: drh tags: trunk)

Optimize calls to sqlite3_mprintf("%z...") so that they attempt to append text onto the end of the existing memory allocation rather than reallocating and copying. (check-in: 4bc8a48e user: drh tags: trunk)
13:46
Remove a lot of the text describing extended format options from the documentation on sqlite3_mprintf() and friends, since that information is now covered by the separate printf.html document. Provide links to that other document. No changes to code. (check-in: 99eec556 user: drh tags: trunk)

22:46
Enhance the string formatter (used by printf()) so that the width and precision of string substitution operators refer to characters instead of bytes when the alternate-form-2 flag ("!") is used. Also fix the %c substition to always work within unicode, regardless of the alternate-form-2 flag. (check-in: c883c4d3 user: drh tags: trunk)

13:53
Fix an assert so that it compares two CellInfo objects field by field instead of using memcmp(). Memcmp() does not work on x86 because of uninitialized padding bytes. (check-in: 88258770 user: drh tags: trunk)
2018-02-18

20:00
On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() after writing N bytes of content, to force a write-queue flush in the underlying OS. This is an experimental hack that is not expected to land on trunk. (Leaf check-in: b18cc5fe user: drh tags: write-queue-flush-hack)

Fix another point in zonefile.c so that all files are opened in either "rb" or "wb" mode. (check-in: fb1c2277 user: dan tags: zonefile)
15:17
When calling fopen() in the zonefile extension, use modes "rb" and "wb" instead of "r" and "w". This makes no difference on unix, but is required when accessing binary files on other systems. (check-in: 4bb854dd user: dan tags: zonefile)

18:02
In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound to persistent SQL statements using SQLITE_STATIC, the binding is replaced with an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer to the persistent statement using sqlite3_next_stmt() and attempt to access the freed buffer using sqlite3_expanded_sql() or similar. (check-in: 2a5f813b user: dan tags: trunk)

Remove the "include <io.h>" win32 dependency from the zipfile extension. (check-in: cb3feb3b user: dan tags: trunk)
16:20
Remove the time() dependency from the zipfile extension. Use SQLite VFS methods instead. (check-in: 0702fb56 user: dan tags: trunk)
08:14
In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. (check-in: 22a228ed user: dan tags: branch-3.19)
08:08
Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. Cherrypick of [49e58e645e]. (check-in: 1b394679 user: dan tags: branch-3.19)

14:01
In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. (check-in: b3122db1 user: dan tags: trunk)

Fix a typo in the MSVC makefile. (check-in: 89e5720a user: drh tags: location-function)
15:04
Change the function name to sqlite_unsupported_offset(X). Only enable the function if compiled with -DSQLITE_ENABLE_OFFSET_SQL_FUNC. The makefiles add that definition to shell builds. (check-in: 7a7f826e user: drh tags: location-function)

22:09
The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. (check-in: 0fdf97ef user: drh tags: trunk)

18:19
Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. (check-in: 1b22b42e user: drh tags: trunk)
17:36
The previous check-in had an error in the coverage reporting logic. (Closed-Leaf check-in: ec9b19eb user: drh tags: lemon-improvements)
17:14
Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. (check-in: 9dce4650 user: drh tags: lemon-improvements)
16:13
In the lemon-generated parser, do not report the End-of-input character and the wildcard character as missed coverage. (check-in: 3fe96487 user: drh tags: lemon-improvements)

04:15
Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. (check-in: 7eb0198d user: drh tags: lemon-improvements)

23:38
In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. (check-in: 7bfe7a36 user: drh tags: lemon-improvements)

Increase the version number for the next release - which is still months away but there have been significant query planner enhancements since the previous release. (check-in: 457eedfa user: drh tags: trunk)
20:51
Reactivate query flattening when the result set of the outer query has no function calls or subqueries. This is a partial reversal of check-in [c9104b59]. Co-routines are still preferred if the outer query has a complex result set, but for simple results sets, query flattening is used. Check-in [4464f40ccd7] is completely backed out due to this change. (check-in: d17ef7d1 user: drh tags: trunk)

2017-10-27
23:28
I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down. (Closed-Leaf check-in: 0926df09 user: drh tags: mistake)

Avoid using lookaside memory for persistent virtual table structures. (check-in: d815f255 user: drh tags: trunk)
02:52
The query planner now always prefers to implement a FROM-clause subquery using a co-routine rather than flattening the subquery into the outer query. (check-in: c9104b59 user: drh tags: trunk)

17:29
Remove the (undocumented) query-planner control that prevents a "SELECT ALL" subquery in FROM clause from being implemented as a co-routine. This control was added by [a29e117d7ec], where it was called a "stop-gap". (check-in: ff2f5a31 user: drh tags: trunk)
16:56
Fix over-length source code lines in select.c. No logic changes. (check-in: fd3267ef user: drh tags: trunk)
13:47
Fix an issue introduced by check-in [4cd2a9672c59] (2017-03-03) that could allow a negative value in the 3rd parameter to memmove() when defragmentPage() is called on a btree page with a corrupted freeblock list. The corruption is now detected early and results in an SQLITE_CORRUPT return before the memmove() is reached. (check-in: 5b9ae693 user: drh tags: trunk)
01:58
Add new routines to simplify dealing with collating sequences in expressions: sqlite3ExprNNCollSeq() and sqlite3ExprCollSeqMatch(). (check-in: 490e488e user: drh tags: trunk)

2017-09-27
16:51
Disable tests for the LIKE optimization when ICU is enabled, since the LIKE optimization only works for the built-in LIKE operator and ICU overrides the built-in. (check-in: f5ef2e1b user: drh tags: trunk)
2017-09-25
09:37
Add an extra snapshot related test case. (check-in: 24a95e14 user: dan tags: trunk)

2017-09-22
20:18
Merge in all the trunk enhancements of the previous 7 months. The LIKE optimization has stopped working when there is an ESCAPE - that problem will be addressed in a subsequent check-in. (Leaf check-in: 8d2a1cca user: drh tags: est_count_pragma)
16:23
Use the updated Win32 VFS semantics for winOpen from check-in [5d03c738e9] for WinRT, et al, as well. (check-in: 2c03d8b8 user: mistachkin tags: trunk)
12:52
Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. (check-in: 403b88a8 user: drh tags: trunk)
11:09
Cherrypick [ec37ad6d08] into this branch. With this patch, if SQLITE_SHARED_MAPPING is defined at build-time SQLite will use a single memory mapping for multiple connections to the same database file within a single process. (check-in: c7a5880d user: dan tags: begin-concurrent)
10:49
Merge latest trunk changes into this branch. (check-in: 307b802e user: dan tags: begin-concurrent)

2017-09-21
20:43
In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. (check-in: 5d03c738 user: drh tags: trunk)
20:03
In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. (check-in: fa3f5bcc user: drh tags: trunk)

Fix a potential use of an uninitialized pointer in RTree following an OOM error. (check-in: fd4ec0cd user: drh tags: trunk)
10:24
Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. (check-in: 65765222 user: drh tags: trunk)
01:04

13:16
Minor simplification of error message generation during compound query code generation. (check-in: a9447193 user: drh tags: trunk)
09:40
The out-of-bounds read on recovery fix of check-in [378afa16381a222a] caused problems for some corner-case error conditions. This alternative fix appears to work better. (check-in: 74f399d8 user: drh tags: trunk)

2017-09-17
19:45
Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. (check-in: 29227d00 user: drh tags: trunk)
2017-09-16

Fix another harmless compiler warning. Get the MSVC makefile working with unionvtab. (check-in: d49639c2 user: drh tags: trunk)
20:22
Suppress harmless compiler warnings in union-vtab. (check-in: 4d147a1e user: drh tags: trunk)
20:17
Remove an unused variable from unionvtab.c. (check-in: a447fdf1 user: dan tags: trunk)
20:03
Improve the readability of the unionvtab code. (check-in: 5bcf0f86 user: dan tags: trunk)
19:51
Have unionvtab support constraints on the column that corresponds to the INTEGER PRIMARY KEY field of the underlying source tables in the same way as rowid. (check-in: 4a6c416f user: dan tags: trunk)
18:50
Add test cases to unionvtab.test. (check-in: 6c9128e1 user: dan tags: trunk)
18:19
Add the union-vtab extension - still experimental and under active development. (check-in: 948f9504 user: drh tags: trunk)
17:34
Do not use the flattening optimization for a sub-query on the RHS of a LEFT JOIN if that subquery reads data from a virtual table. Because it prevents the planner from creating an automatic index on the results of the sub-query, the flattening optimization sometimes slows things down in this case. (check-in: 9dbae1df user: dan tags: trunk)
17:13
Avoid creating an automatic index on the RHS of a LEFT JOIN to optimize an IS term. Fix for [ce68383b]. (check-in: d2f0b2e8 user: dan tags: trunk)
14:41
Change the default command-line shell history depth to 2000 lines. (check-in: 0b69aa7e user: drh tags: trunk)

Enhance error detection and fix other issues in unionvtab code. (check-in: 9c3f1b9a user: dan tags: union-vtab)
20:21
Merge all the latest fixes and enhancements from trunk. (check-in: e181225d user: drh tags: apple-osx)
19:37
Try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. This is a cherry-pick of [6df18e949d36] with bug fixes. (check-in: cd6ac078 user: drh tags: branch-3.8.9)
19:25
When checking for the WHERE-clause push-down optimization, verify that all terms of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket [f7f8c97e97597]. (Closed-Leaf check-in: adc082c1 user: drh tags: push-down-backport)
19:14
Do not apply the WHERE-clause pushdown optimization to terms that originate in the ON or USING clause of a LEFT JOIN. Fix for ticket [c2a19d81652f40568c]. (check-in: 52674f94 user: drh tags: push-down-backport)
19:07
For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Cherry-pick from [6df18e949d36]. Still need to backport bug fixes associated with that check-in. (check-in: 043d6ce8 user: drh tags: push-down-backport)
18:45
Merge all changes from branch-3.20. Improvements to the fts5() extension interface. Work around a gcc/valgrind bug in the sqlite3_value_pointer() interface. (check-in: e0aca7d2 user: drh tags: trunk)
17:46
Interchange to branches within an "if" statement in sqlite3_value_pointer() in order to work around a bug in gcc. (Closed-Leaf check-in: 8a606e4a user: drh tags: branch-3.20)

Improved the interface to the fts5() extension mechanism for enhanced security. (check-in: bc78235f user: drh tags: branch-3.20)
13:37
Merge the pointer-type enhancement from the 3.20 branch. (check-in: 9e8e1c4a user: drh tags: trunk)
12:41
Comment changes clarifying details of the pointer-type parameter. No changes to code. (check-in: e4579e50 user: drh tags: branch-3.20)
12:27
Add the pointer-type parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a static string that must match (according to strcmp()) or else the pointer is passed as a NULL. This is a security measure to prevent crossing pointers between different extensions. (check-in: e1196567 user: drh tags: branch-3.20)
11:39
Improve the sqlite3_result_pointer() interface so that it cannot be faked using sqlite3_result_null() and sqlite3_result_subtype(). (Closed-Leaf check-in: c13264d5 user: drh tags: pointer-types)
09:30
Use integer handles for fts3 cursors for a small performance improvement. (Closed-Leaf check-in: f4f7196b user: dan tags: union-vtab, fts3-int-cursor)
00:40
Add an experimental "pointer type" parameter to sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer(). The pointer type is a string that must compare equal using strcmp() or else the pointer comes through as a NULL. (check-in: 211cce04 user: drh tags: pointer-types)
2017-07-15
20:48
Add the "unionvtab" virtual table extension in ext/misc/unionvtab.c. (check-in: 62a86aa6 user: dan tags: union-vtab)
20:44
Merge the fix for ticket [a4e06e75a9ab61a12] from trunk. (check-in: b64d64c8 user: drh tags: branch-3.20)
20:33
Fix a register allocation problem in PRAGMA integrity_check that caused the same register to be used for two different purposes on the first ATTACHed database if the schema for the ATTACHed database was noticable more complex than the schema for the first database. Fix for ticket [a4e06e75a9ab61a1]. (check-in: 253945d4 user: drh tags: trunk)

15:42
Include a hint in the header comment of the LSM1 makefile about how to set the LSMOPTS variable. (check-in: b5e3b264 user: drh tags: trunk)
15:32
Update the Makefile for LSM1 so that the LSMOPTS can be set prior to including the Makefile, in order to add platform arguments such as -fPIC. (check-in: fe319bcd user: drh tags: trunk)
15:18
Fix a typo in the header comment to the remember extension. No code changes. (check-in: 604b9664 user: drh tags: trunk)
15:14
Change the name of the STMT virtual table to SQLITE_STMT. Also remove the first column of that virtual table, which was a pointer leak. (check-in: 1bc4e934 user: drh tags: trunk)
13:24
Minor updates to requirements marks and documention. No changes to code. (check-in: 8f6dd5e2 user: drh tags: trunk)

Fix harmless compiler warnings in the readline tab-completion logic of the command-line shell. (check-in: 271ca4ac user: drh tags: trunk)
2017-07-13
22:39
Improved documentation for the new sqlite3_bind_pointer() interface and its cousins. (check-in: 889968bd user: drh tags: trunk)

Improvements to the documentation for SQLITE_PREPARE_PERSISTENT. No code changes. (check-in: 26577814 user: drh tags: trunk)
21:06
Make the freelist format a separate feature from the page-level locking. Freelist format is now configure using "PRAGMA freelist_format". (check-in: dcc40797 user: dan tags: server-process-edition)
20:11
Fix documentation typo. No changes to code. (check-in: 9319f7b7 user: drh tags: trunk)
19:11
Update header comments on the carray() and remember() extensions to bring out the fact that the pointer arguments must be bound using sqlite3_bind_pointer(). (check-in: 55f53965 user: drh tags: trunk)
18:09
Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. (check-in: 72de49f2 user: drh tags: trunk)
17:56
Fix an incorrect type signature for the loadable extension pointer for sqlite3_result_pointer(). (Closed-Leaf check-in: 0bd7875b user: drh tags: bind-pointer)
17:54
Add the three new pointer interfaces to the loadable extension mechanism. Update sqlite3_value_subtype() documentation to remove the statement about it not being used internally. (check-in: e5a51803 user: drh tags: bind-pointer)
17:48
Update the FTS3 extension to use sqlite3_result_pointer() and sqlite3_value_pointer() for passing FTS3 cursor objects from the table into functions such as snippet(). (check-in: 0fa2e170 user: drh tags: bind-pointer)
17:34

Smaller and faster implementation for vdbeFreeOpArray() and freeP4(). (check-in: 0c805935 user: drh tags: trunk)
18:05
Fix harmless compiler warnings about incomplete structure initializers. (check-in: 604c11d1 user: drh tags: trunk)
17:26
Remove unnecessary EP_Leaf settings on the Expr object. (check-in: f951c8b7 user: drh tags: trunk)
17:08
The EP_Resolved flag on the Expr object is not required for correctness nor performance, so remove it. (check-in: 54f55d3b user: drh tags: trunk)
14:10
Clarification and simplification and result column naming logic. (check-in: 68824a43 user: drh tags: trunk)

Compile cleanly with SQLITE_OMIT_UTF16. (check-in: 783100b8 user: drh tags: trunk)
2017-07-11
20:36
In lsm, attempt to unmap the database file before truncating it when disconnecting. A mapped file may not be truncated on win32. (check-in: 39069941 user: dan tags: trunk)
19:55
Simplify the way in which the database file is truncated when the last connection disconnects. Also ignore the error code from the xTruncate call - as truncating a database file is always optional. (check-in: b0a49d90 user: dan tags: trunk)
18:38
Add SQL function usleep() to test program tserver.c. (check-in: 8cbe8f2b user: dan tags: server-process-edition)
18:11
Fix harmless compiler warnings in the core. (check-in: 55e93f25 user: drh tags: trunk)

Add support for tab-completion (using the ext/misc/completion.c virtual table) to the command-line shell. (check-in: 95cd1d9f user: drh tags: trunk)
13:34
Change the src/shell.c file so that it is generated from a new script at tool/mkshellc.tcl and the template file src/shell.c.in, and automatically includes the extensions it needs out of ext/misc. (check-in: 17e0bb12 user: drh tags: trunk)
02:53
Fix a backup2 test case so that it works on FreeBSD. (check-in: 724819b4 user: drh tags: trunk)
02:05
Add the "phase" output column on the COMPLETION table-valued function, for debugging. Improved comments on the implementation. (check-in: 0e213555 user: drh tags: trunk)
01:38
The COMPLETION virtual table now looks at the names of databases, tables, and columns in addition to SQL keywords. (check-in: 1cc97711 user: drh tags: trunk)
00:09
Incomplete implementation of the COMPLETION table-valued function. So far it only works for SQL keywords. (check-in: caefbc72 user: drh tags: trunk)

21:32
Fix harmless compiler warnings in lsmtest. (check-in: bd8a1fb9 user: mistachkin tags: trunk)

Cleanup header usage in lsmtest for files that require _O_BINARY. (check-in: f3a6a64e user: mistachkin tags: trunk)
18:52
Updates to the repository README.md file. (check-in: 7bfd3ab7 user: drh tags: trunk)
18:33
In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). (check-in: a82a9bea user: dan tags: trunk)
18:04
Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. (check-in: bde431b1 user: drh tags: trunk)
17:00
When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. (check-in: c4cb9048 user: drh tags: trunk)
16:38
Additional debugging Noop-comment in the constraint generator when wheretrace is enabled. (Closed-Leaf check-in: 0ca7474f user: drh tags: defer-where-subqueries)

Fix another problem on this branch. (check-in: a4fc9811 user: dan tags: defer-where-subqueries)
14:39
Fix a problem causing non-covered WHERE terms to be evaluated before covered WHERE terms. (check-in: 7d3cb39f user: dan tags: defer-where-subqueries)
14:33
When testing non-indexed WHERE constraints, test those that involve correlated sub-queries last of all. This increases the chances of not having to run the sub-query at all. (check-in: 1f9c1f35 user: dan tags: defer-where-subqueries)
13:24
For sqlite3TreeView() debugging output, show the Expr.flags field on scalar subqueries. (check-in: dc857a96 user: drh tags: trunk)
12:07
Update error message text for standard error codes to better describe the latest usage of those error codes. Modify sqlite3_open_v2() so that it does return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad open flags, so that sqlite3_errmsg() does not report "out of memory" in that case. (check-in: f27b6370 user: drh tags: trunk)
11:17
Remove the error message text from disused error codes such as SQLITE_EMPTY and SQLITE_FORMAT. (check-in: 871752f2 user: drh tags: trunk)
2017-07-09
18:55
Always make "column%d" column-names 1-based, never 0-based. (check-in: 70096c50 user: drh tags: trunk)
00:30
Make sure the columns of a VALUES() clause are named "column%d" even if the VALUES() clause is a subquery in the FROM clause of an outer query. (check-in: acf3b9cc user: drh tags: trunk)
2017-07-08
22:30
Add the --icc, --gcc7, and --orm options to the speed-check.sh test script. (check-in: 70dae08a user: drh tags: trunk)

Support read-only MVCC transactions in server-mode. Started using "BEGIN READONLY". (check-in: 5a043aa8 user: dan tags: server-process-edition)
18:27
Disable compiler intrinsics when using the Intel C Compiler. (Leaf check-in: dbb59f61 user: drh tags: icc-fix)
01:01
Fix the covering index OR optimization (check-in [fcbd6abd]) so that it works with SQLITE_MAX_ATTACHED>30. Broken by a bad cherry-pick merge. (check-in: d227de8a user: drh tags: branch-3.8.9)
2017-07-07
22:58
Merge in all the latest trunk enhancements. (check-in: 7f48f6ab user: drh tags: apple-osx)
22:47
Basic test cases for PRAGMA secure_delete=FAST. (check-in: 0c246017 user: drh tags: trunk)
22:39
Fix test cases in wal2.test due to the fact that Darwin checks to see if the SHM file is writable before attempting to open in read/write. (check-in: 6b618b18 user: drh tags: apple-osx)
21:20
Fix comment in the Win32 VFS for lsm1. (check-in: 12a421bc user: mistachkin tags: trunk)
21:15
For lsmtest, use a more portable means of setting open() files to binary. (check-in: aea6e0ff user: mistachkin tags: trunk)
20:35
Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. (check-in: 54a38555 user: mistachkin tags: trunk)
20:33
Avoid even trying to open a SHM file read/write in WAL mode if we know that the file is read-only. This avoids scare security log messages. (check-in: d9d92781 user: drh tags: apple-osx)
20:06
Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. (check-in: 38978ce6 user: drh tags: trunk)
19:43
Change the error message text for SQLITE_ERROR to omit the part about "missing database" as that meaning is now obsolete (since approx SQLite 2.0). (check-in: 732f90d6 user: drh tags: trunk)
19:22
Fix typos in Win32 VFS for lsm1. (check-in: 0961ec87 user: mistachkin tags: trunk)

18:31
Add support for LSM_DEBUG to the MSVC makefile for lsm1. (check-in: 277a7fed user: mistachkin tags: trunk)
18:06
In the command-line shell, when running ".schema" give a sensible error when the database file is locked. (check-in: cc329eb8 user: drh tags: trunk)
17:57
Fix the usleep() macro in the Win32 test code for lsm1. (check-in: 63599fa5 user: mistachkin tags: trunk)
17:43
Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. (check-in: e0b6ae92 user: drh tags: trunk)
17:33
Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. (Closed-Leaf check-in: 2f3c3781 user: drh tags: list-pragmas)
16:46
Improve clarity in the Win32 VFS for lsm1. (check-in: 9c7a9e80 user: mistachkin tags: trunk)

Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk.

Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid.

When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) (check-in: f489b5bb user: drh tags: trunk)
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN.

01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1 user: drh tags: skip-ahead-distinct)

Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. (check-in: 6c627e50 user: drh tags: trunk)
16:32
Add the --recovery-mode option to the CLI ".dump" command. This involves enhancing the "PRAGMA reverse_unordered_selects" command to accept a "TOGGLE" option. Recovery mode used to be always on. Now it is opt-in. Not sure this is the correct approach. Also not sure if TOGGLE is a good feature to have on boolean PRAGMA statements. (Closed-Leaf check-in: 5dc82a15 user: drh tags: dump-recovery)

15:35
The sqlite3_blob_close() interface can cause recursive invocations of nodeBlobReset() in RTREE. Make sure that does not cause problems. (check-in: 88333441 user: drh tags: rtree-sqlite3_blob)
14:40
Change RTREE so that the sqlite3_blob object is closed whenever the cursor count drops to zero and there is not a pending write transaction. (check-in: 9bb4eafe user: drh tags: rtree-sqlite3_blob)

2017-01-28
20:46
In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. (check-in: 4fe879d4 user: drh tags: trunk)

01:52
In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". (check-in: 58f02e6e user: drh tags: trunk)
01:25
Another micro-optimization in accessPayload(). Slightly smaller and faster. (check-in: c012619b user: drh tags: trunk)
01:13
Performance optimization in accessPayload(). (check-in: ebb1fd98 user: drh tags: trunk)
00:31
Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. (check-in: 68e7a8c6 user: drh tags: trunk)
2017-01-26

00:58
Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. (check-in: 50e60cb4 user: drh tags: trunk)
2017-01-25
20:55
Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. (check-in: 4801bd59 user: drh tags: trunk)

18:40
Add the --mmap option to the kvtest utility program. (check-in: 4948f7e6 user: drh tags: trunk)
16:56
Optimization: Try to avoid unnecessary btree searching when repositioning a cursor to the next row. (check-in: ee793d30 user: drh tags: trunk)
15:58
Add the missing SQLITE_API symbol to test_delete.c (it is not added automatically as this file is not part of the amalgamation). (check-in: 7a4f512d user: dan tags: trunk)
07:06
Fix a problem preventing FTS5 from correctly passing the FTS5_TOKENIZE_PREFIX flag to custom tokenizer implementations. (check-in: 03c60134 user: dan tags: trunk)

A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85 user: drh tags: btree-moveto-neighbor)
16:54
B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb20 user: drh tags: btree-moveto-neighbor)
16:27
Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1 user: drh tags: trunk)

Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. (check-in: ffda1d1e user: dan tags: trigger-trace)
15:55
In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a user: drh tags: trunk)
15:30
A proof-of-concept for running sqlite3_blob_open() without using OP_Column when operating on a pure key/value table. This demo does not include any corrupt database checking. Uses about 3% fewer CPU cycles on a key/value performance test. (Leaf check-in: 4cda3b30 user: drh tags: kv-access-opt-demo)
14:11
Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a53 user: drh tags: trunk)

Add option "--stats" to test program kvtest. Specifying --stats causes kvtest to output information similar to the shell tool option of the same name. (check-in: 90291327 user: dan tags: trunk)
16:09
Get the "--testset rtree" option working on speedtest1. Add the --rtree, --lookaside, and --clang options to the speed-check.sh script. (check-in: 87b640c8 user: drh tags: trunk)
00:40
Minor performance optimizations to sqlite3_blob_open() and sqlite3_blob_reopen(). (check-in: 52a61967 user: drh tags: trunk)
2017-01-19
21:20
If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed38521 user: drh tags: trunk)
18:20
In the 'vtshim' extension, avoid accessing freed memory when handling errors from xCreate/xConnect. (check-in: ffd559af user: mistachkin tags: trunk)

22:47
In the 'windirent' test module, use a macro for the hidden/system attribute checking. (check-in: a84a08d0 user: mistachkin tags: trunk)
22:19
Remove superfluous option to Tcl 'lsort' in the vtabH test file. (check-in: b92cc6e5 user: mistachkin tags: trunk)

Fix handling of initial hidden and/or system files in the opendir() implementation for Windows. No changes to non-test code. (check-in: 26dd42b4 user: mistachkin tags: trunk)
20:14
Add temporary code to record and report on the set of b-tree pages read and written by the current transaction. This is likely still buggy. (check-in: 2a8f6c89 user: dan tags: transaction-pages)

When determining sector sizes on Windows 7 and Vista, make sure the target file is on the same volume as corresponding root directory. (check-in: de699ead user: mistachkin tags: winSectorSize)
2017-01-17
10:41
Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb user: dan tags: trunk)
00:10
Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6 user: drh tags: trunk)
2017-01-16

Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. (check-in: def29333 user: drh tags: trunk)
19:37
The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. (check-in: 2f481b85 user: drh tags: trunk)

Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. (check-in: f7ab01f2 user: drh tags: trunk)
2016-12-18
17:42
Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. (check-in: 165c0446 user: drh tags: trunk)

16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. (check-in: 850877d1 user: dan tags: trunk)

Avoid an unnecessary memset() in the sqlite3BtreeInsert() routine. (check-in: 35ecd4eb user: drh tags: trunk)
12:58
Reorder the fields in the VdbeCursor object so that those that need to be bulk zeroed on allocation are grouped at the beginning, and the memset() only runs over those fields that really need it. (check-in: 8165f88b user: drh tags: trunk)
04:06
Avoid signed integer overflow when dealing with a LIMIT and OFFSET whose sum exceeds the maximum integer value. (check-in: c9bdf7ad user: drh tags: trunk)

Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. (check-in: dc453b34 user: drh tags: trunk)
2016-11-29
20:39
The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31. Change the actually implementation so that the answer given is really NULL.

When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?".

17:18
Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. (check-in: 7908fc60 user: dan tags: trunk)
2016-09-01
14:03
Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. (check-in: f4ba894a user: dan tags: trunk)
09:35
If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed.

14:04
Add the "dbhash.exe" utility program that computes a SHA1 hash over the invariant content of an SQLite database file. Free space in the file, the page size, auto_vacuum status, text encoding, and so forth do not change the hash. Only the content matters. (check-in: f48a4ad3 user: drh tags: trunk)

Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree.

Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and make it only work for table btrees. Change sqlite3BtreeDataSize() into sqlite3BtreePayloadSize() and make it work for all btrees.

Remove an unnecessary malloc from the vfsstat extension. (check-in: 24f258c2 user: drh tags: trunk)
17:23
Enhance the sqlite3_load_extension() interface to permit extensions to return SQLITE_OK_LOAD_PERMANENTLY which will prevent the extensions from unloading when the database connection closes. (Closed-Leaf check-in: d3f99a5e user: drh tags: load-permanently)
15:22
Enhance "PRAGMA compile_options" so that it shows the version of the compiler used to generate the executable, for common compilers. (check-in: 6a0f2009 user: drh tags: trunk)
15:09
Update the amalgamation-tarball configure script so that it can use header file "readline/readline.h" with library file "libedit". (check-in: cbf72b04 user: dan tags: trunk)
15:03
Enhance the sqlite3_load_extension() API so that the first parameter (the "db" parameter) can be NULL. An extension that is not associated with any database connection remains loaded for the life of the process. (Closed-Leaf check-in: 3a461043 user: drh tags: persistent-extensions)
14:53
Add the vfsstat.c loadable extension - a VFS shim that measures the amount of I/O, and an eponymous virtual table that is used to extract and view the measurements. (check-in: 0987487d user: drh tags: trunk)
00:13
Clang can define _MSC_VER in some circumstances; therefore, check for Clang first. (Closed-Leaf check-in: 3f710bc3 user: mistachkin tags: ctimeCompiler)

2016-05-26
20:56
Add a new OP_SeekRowid opcode, that combines the functions of OP_MustBeInt and OP_NotExists. This makes the code slightly smaller and faster. (check-in: ffe80a1b user: drh tags: trunk)

18:50
Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. (check-in: 61e239bc user: drh tags: trunk)
16:20
Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab user: dan tags: trunk)
00:40
Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: 3b28b68e user: drh tags: trunk)
2016-05-23
21:56

14:11
For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. (check-in: 559733b0 user: drh tags: trunk)
13:44
Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc user: drh tags: orderby-limit)

A few simple test cases for the ORDER BY LIMIT optimization. (check-in: 08849eab user: drh tags: orderby-limit)
2016-05-19
22:40
Appears to work now. Needs test cases, more comments, and code optimization. (check-in: 990fe50c user: drh tags: orderby-limit)
22:13
In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. (check-in: 852d1eda user: drh tags: orderby-limit)
19:31
Fixup comments on wctrlFlags value definitions. (check-in: 58b516e8 user: drh tags: trunk)

Enhance the scrub utility program so that it does a FULL checkpoint prior to starting the backup, to ensure that the database file content matches what needs to be backed up without having to look at the WAL file. (Closed-Leaf check-in: ab1c5ce5 user: drh tags: scrub-backup)
17:11
Merge the latest changes from trunk. (check-in: 5021dfe1 user: drh tags: scrub-backup)

18:47
Corrections to comments on the whereScanInit() interface. (check-in: ab7ab415 user: drh tags: trunk)
16:49
For DELETE operations, make sure that seeks on the main table are not deferred, since if they are and none of the indexes reference columns of the table, the seek might never occur until the OP_Delete opcode, which is too late. Fix for ticket [16c9801ceba49]. (check-in: 93a2bace user: drh tags: trunk)

16:44
If a call to sqlite3rbu_close() on an rbu handle opened by sqlite3rbu_vacuum() returns other than SQLITE_OK, delete the contents of the rbu_state table. This ensures that if an RBU vacuum operation either completes successfully or encounters an error, the next call to sqlite3rbu_vacuum() with the same parameters starts a new RBU vacuum operation.

The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!).

Always assume that indexed expressions can generate a NULL. Get indexed expressions working for the case of two or more expressions in the same index. (check-in: cc60321a user: drh tags: index-expr)
18:13
Case should not be significant when comparing function names. (check-in: e2f1caf1 user: drh tags: index-expr)
17:34
Make the distinction between truly deterministic functions and date/time functions which only return the same answer for a single query. Only truly deterministic functions are allowed in indexes. Add new expression index test cases. (check-in: c77554b5 user: drh tags: index-expr)
15:58
Improved analysis and usage of indexed expressions in the query planner. (check-in: f8893696 user: drh tags: index-expr)

Enhance the json_extract() function so that if given multiple PATH arguments it will return a JSON array with all of the answers. Also update comments within the json1 extension to reflect stricter interpretation of JSON and PATH arguments. (check-in: 1da60c3d user: drh tags: trunk)
19:03
Link the json1 extension into the command-line shell by default. (check-in: 2e8e239c user: drh tags: trunk)

18:30
New test cases for the json1 extension. (check-in: daff4832 user: drh tags: trunk)

Fix the build with -DSQLITE_OMIT_VIRTUALTABLE. (check-in: 752918de user: drh tags: trunk)
16:02
Do not consider an empty string to be valid JSON. Add some additional JSON test cases. (check-in: fd19ff02 user: drh tags: trunk)

2015-08-28
20:07
Back out the json_check() routine. Instead, throw an error if the input to a json function (other than json_valid()) is not valid JSON. (check-in: dc9ce7b1 user: drh tags: trunk)

13:27
Disable the read-only WAL-mode database tests on the apple-osx branch because read-only WAL-mode databases are specifically disallowed by Apple-specific changes. (check-in: bd911496 user: drh tags: apple-osx)
09:27
Merge latest trunk changes with this branch. (check-in: 57bc0194 user: dan tags: begin-concurrent)

03:33
Enhance the json_insert(), json_replace(), and json_set() functions with the ability to add JSON instead of text if the argument is text and if the PATH begins with '$$' instead of just '$'. (check-in: 44f103d8 user: drh tags: trunk)

19:10
Add miscellaneous test cases for concurrent transactions. (check-in: 779b1d0e user: dan tags: begin-concurrent)
17:16
If "PRAGMA integrity_check" is run while the database is being written by a CONCURRENT transaction, do not consider unreferenced pages to be an error. They may be part of the free-page list, which is not visible at the b-tree layer when running a CONCURRENT transaction. (check-in: f32b57b4 user: dan tags: begin-concurrent)
16:57
Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. (check-in: efaabdb7 user: drh tags: index-expr)
16:01
Test that if a corrupt wal-index header is encountered when attempting to commit a concurrent transaction, SQLITE_BUSY_SNAPSHOT is returned to the caller. (check-in: c746e0bd user: dan tags: begin-concurrent)

22:06
Remove duplicated line of code. (check-in: 47280f2a user: mistachkin tags: begin-concurrent)

20:21
Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. (check-in: bed42116 user: drh tags: trunk)

Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. Also, the URI syntax may be used on the command line to specify the name of the database file to examine, so an alternative VFS may be requested using a URI parameter.

2015-08-03
17:03
Add the "--uri" option to utility program "showdb". This option causes showdb to use sqlite with the SQLITE_OPEN_URI option to open the database file, instead of opening it directly using the OS open() function. (check-in: 90e34d51 user: dan tags: showdb-uri-option)
13:44
Allow a VIEW to reference undefined tables and functions when initially created. The error report is deferred until the VIEW is used. This allows views to be created before subviews and tables that the view references. (check-in: 70b57daf user: drh tags: trunk)

"test" targets on all makefiles use --verbose=file --output=test-out.txt. Add the new "quicktest" target to all makefiles - designed to run in under three minutes. The --quick option on releasetest.tcl now uses quicktest. (check-in: 6ddef2ad user: drh tags: trunk)
17:20
Resolve FROM-clause subqueries after query planning instead of before. Greatly reduce the estimated cost of automatic indexes for VIEWs and ephemeral tables since performance problems there cannot be mitigated via a CREATE INDEX. (check-in: a1eaf171 user: drh tags: view-optimization)

2015-06-08
22:59
Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs. Except this does not currently work because the query planner needs an estimated of the number of rows in the manifested table. Work in progress. (check-in: cabf2187 user: drh tags: view-optimization)
19:15
Add the valgrindfuzz target to unix makefile. (check-in: e62aed01 user: drh tags: trunk)

2015-06-06
20:12
Split out the bulk of the actual VDBE code generation logic from where.c into a new file, leaving behind the analysis logic. This makes the original where.c smaller and hopefully easier to edit. (check-in: faa0e420 user: drh tags: view-optimization)
19:23
Fix a comment in fts5.h. (check-in: e964b587 user: dan tags: fts5)

An attempt to allow automatic index creation on subqueries accessed via co-routine. (check-in: 521345ad user: drh tags: coroutine-autoindex)
01:35
Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d user: drh tags: trunk)

Oops - the deephemerialization needs to occur before the move, not after. Was: Rather than try to keep track of the parent of an ephermeral register when the register moves, just deephemeralize all registers touched by the OP_Move opcode. (Closed-Leaf check-in: 091cfe8e user: drh tags: mistake)
12:44
Shift the Mem.pScopyFrom pointer in the correct direction in OP_Move. Fix for a defective check-in [a2135ad13049] and ticket [d6352363751]. Debugging code only - does not affect normal operation. (check-in: add4e043 user: drh tags: trunk)

Add the INITMODE test-control. (check-in: 5940af8e user: drh tags: initmode-testctrl)
15:53
Improvements to the DELETE code generator for the one-pass case. Avoid some OP_Goto instructions. Read content from the index cursor if the index cursor is valid and was used to locate the row that is to be deleted. (Closed-Leaf check-in: 58cc257a user: drh tags: one-writable-btree)
14:48
Avoid overlength command lines in Makefile.msc when using TOP= with a large directory name. (check-in: 0cdd59bf user: drh tags: one-writable-btree)

Optimize range constraints on the rowid column of fts3/4 tables even if there is no MATCH clause in the query. (check-in: 85dc1262 user: dan tags: trunk)
02:26
Experimental sqlite_db_config() setting to disable writing to all btrees except for one btree with a particular root page. (check-in: 23054110 user: drh tags: one-writable-btree)
2015-01-28
20:37
Add missing VdbeCoverage() macros to the sqlite3_index_writer() implementation. (check-in: 6f8cda26 user: drh tags: ota-update)
15:30
When a "full", "restart" or "truncate" checkpoint is attempted, return SQLITE_BUSY if a reader prevents the checkpointer from copying any frames at all into the database file. (check-in: f2700040 user: dan tags: ota-update)
12:27
Correctly detect errors returned by walCheckpointStart() due to OOM. (check-in: 8e878c20 user: drh tags: ota-update)

Fix a bug in the fts3 snippet() function causing it to omit leading separator characters from snippets that begin with the first token in a column. (check-in: adc9283d user: dan tags: trunk)
18:43
Improve the performance of fts3/4 queries that use the OR operator and at least one auxiliary fts function. (check-in: 245e8730 user: dan tags: trunk)
13:17
Fix a (almost always harmless) read past the end of a memory allocation that comes about because the Expr.pTab field is checked on an EXPR_REDUCEDSIZE Expr object before checking the Expr.op field to know that the Expr.pTab field is meaningless. (check-in: e098de69 user: drh tags: trunk)
2015-01-25
20:19
The va_list argument cannot take on a NULL value and cannot be compared with NULL on some platforms (ex: ARM). So do not attempt to do so. (check-in: 1964e656 user: drh tags: trunk)
2015-01-24
19:57
Have fts5 store rowids in ascending order. Query speed is virtually the same regardless of rowid order, and ascending order makes some insert optimizations easier. (check-in: 5206ca60 user: dan tags: fts5)
12:12
In the command-line shell, make sure stderr is unbuffered so that it automatically flushes. This has always been the case already for unix and on Windows when the output is a console, but apparently was not the case on Windows when the output was a pipe. (check-in: 2a9ea9b4 user: drh tags: trunk)
2015-01-23

Add further tests and fixes for fts5. (check-in: 5b295897 user: dan tags: fts5)
12:00
Make sure errors in the FROM clause of a SELECT cause analysis to abort and unwind the stack before those errors have a chance to mischief in the "*" column-name wildcard expander. Fix for ticket [32b63d542433ca67]. (check-in: 9e6eae66 user: drh tags: trunk)

2015-01-19
21:38
Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function. Add assert() statements to the high-speed comparison functions to detect cases where they are inappropriately chosen. Fix for ticket [f97c4637102a3ae72b7911]. (check-in: 59e592f6 user: drh tags: branch-3.8.8)
21:36
Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function.

Add comments and improve the new test case. (check-in: 4ec2aead user: mistachkin tags: expShell)
21:10
There are asserts in place now that will prevent a recurrence of ticket [f97c4637102a3ae7]. Nevertheless, it is good to add some test cases as well. (Closed-Leaf check-in: e02959b9 user: drh tags: tkt-f97c4637)
20:59
Make sure that the KeyInfo.nXField value of ephermeral tables used for ORDER BY and GROUP BY is set correctly, so that the correct comparison function can be choosen by sqlite3VdbeFindCompare(). (check-in: c16bae5e user: drh tags: tkt-f97c4637)

Fix compilation on Cygwin when SQLITE_MAX_WORKER_THREADS is greater than zero. (check-in: 2037442c user: mistachkin tags: trunk)
19:48
An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters. (check-in: bf744b49 user: drh tags: tkt-f97c4637)
19:21
An alternative way of fixing the key comparison bug of ticket [f97c4637102a3ae72b]. (Closed-Leaf check-in: e41376cf user: drh tags: alt1-tkt-f97c4637)

17:28
Add an assert() to verify that the nField+nXField values of a KeyInfo object are never less then the number of columns in a row for a non-corrupt database. This assert() currently fails, which is the root of the problem with ticket [f97c4637102a3ae72b]. (check-in: 083f523d user: drh tags: tkt-f97c4637)

21:26
Simplify some code in rtree, to avoid confusing the optimizer in GCC on some macs: gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00). Prior to these changes, compiling with -O3 would cause incorrect code to be generated. The change to the nodeGetCell() routine is key. The other changes are merely cosmetic details discovered while bug hunting. (check-in: 882181ff user: drh tags: trunk)

Make use of the fdatasync() interface if the HAVE_FDATASYNC macro is true. (check-in: 694228e4 user: drh tags: trunk)
16:49
Improvements to compile-time-option hygiene. Use "#if OPTION" instead of "#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work. Add the "Have-Not" configuration in releasetest.tcl which disables all of the "HAVE_component" compile-time options. (check-in: 9e92a5ed user: drh tags: trunk)
15:21
Add the ability to put comments in the Config and Platform setup sections of the releasetest.tcl script. (check-in: d6f8c899 user: drh tags: trunk)

02:15
In releasetest.tcl: (1) Add the Failure-Detection platform. (2) Re-add the --disable-shared argument on Default that was mistakenly removed by the previous commit. (3) Remove the -ftrapv tests, as we read that -ftrapv does not work in GCC. (check-in: 1f2fb777 user: drh tags: trunk)
01:05
In releasetest.tcl: add options --veryquick and pass-through compiler optimization settings (ex: -O0). Collect the SQLite version number from the main.test output and show it during the summary report at the end. (check-in: e7e7bc1d user: drh tags: trunk)
2015-01-07
19:38
In releasetest.tcl, always use --disable-shared together with --disable-amalgamation because mingw generates a binary that crashes and cannot be debugged using gdb if you don't. (check-in: 19982439 user: drh tags: trunk)

Tests and fixes for fts5 external content tables. (check-in: 047aaf83 user: dan tags: fts5)
20:13
Enhance "INSERT INTO ... VALUES" so that the number of rows in the VALUES clause is not limited by SQLITE_LIMIT_COMPOUND_SELECT, and so that the stack depth is constant regardless of the number of rows in VALUES. (check-in: e1c4a359 user: drh tags: trunk)
20:04
Avoid O(N*N) behavior with very long lists of VALUES. (Closed-Leaf check-in: ee30fb35 user: drh tags: many-VALUEs)
19:16
Handle compound-select statements originating from VALUES clauses as a special case that does not use recursion. (check-in: 9ce9e43a user: drh tags: many-VALUEs)
16:27
Towards getting INSERT statements to except many VALUE terms (more than the limit imposed by SQLITE_LIMIT_COMPOUND_SELECT). This check-in segfaults on a stack overflow. And it is slow. (check-in: c9d65f73 user: drh tags: many-VALUEs)
15:48
Remove some needless recursion from compound SELECT processing. (check-in: fe677d13 user: drh tags: trunk)

Add the ability to specify an alternative compiler (clang instead of gcc) on the default Makefile. Use this in releasetest.tcl to implement an -fsanitize=undefined test. (check-in: c55c05fe user: drh tags: trunk)
19:11
Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (check-in: da408d12 user: drh tags: trunk)

00:08
Make sure the sqlite3BtreeCount() routine does not leave index cursors in an inconsistent state, as doing so might result in an assertion fault inside of sqlite3BtreeKey() called from saveAllCursors() if content is deleted out from under the statement that issued the sqlite3BtreeCount() call. (check-in: 5b1b6970 user: drh tags: trunk)

00:52
Remove the KeyInfo cache (for now - perhaps we will add it back in later - or maybe not since it provides negligible benefit but adds a lot of complexity and thread-safety risk). Add a mutex to ATTACH to deal with a data race. (check-in: 03c443ea user: drh tags: trunk)

00:20
Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides minimal performance improvements, and then only at SQL preparation time, not at runtime, and it has problems with data races in shared-cache mode. We might later add the keyinfo cache back but only enable it when shared-cache mode is off. (check-in: b7489f94 user: drh tags: threadtest4)

2014-12-09
22:24
Fix the sqlite3_table_column_metadata() routine so that it gives the correct answer for the "rowid" column in a WITHOUT ROWID table. Enhance it so that it can be used to check for the existence of a table by setting the column name parameter to NULL.

Lower the default SQLITE_SORTER_PMASZ value back to 10, where it has been for the past couple of releases. Applications that need a larger value can set one. (check-in: 1ba8911c user: drh tags: trunk)
19:07
Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. (check-in: 4f7549ff user: drh tags: trunk)
15:12
Add the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option that causes the "PRAGMA reverse_unordered_selects" setting to be on by default. (check-in: 75a803e6 user: drh tags: trunk)

14:46
Use exponential buffer size growth in StrAccum, as long as the size does not grow to large, to avoid excess memory allocation resize operations. Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. (check-in: a518bc33 user: drh tags: trunk)
13:24
When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. (check-in: 3dda3c93 user: drh tags: trunk)

00:05
In the balance_nonroot() routine, protect the values in aPgno[] array from change during the page sort, so that aPgno[] can be used to avoid unnecessary pointer-map updates for auto_vacuum databases. (check-in: 69c3924f user: drh tags: trunk)
2014-10-30
23:14
Improvements to the wording of some comments. Reinstate an assert() that is only true for non-corrupt database files by adding an "|| CORRUPT_DB" term. (check-in: 67adb448 user: drh tags: trunk)

Add test file e_wal.test. (check-in: fc6920b5 user: dan tags: trunk)
08:02
If a free-slot is found within a page, but using that free-slot would fragment the page further and there are already at least 60 fragmented bytes, degragment the page. This matches the behaviour of the trunk. (Closed-Leaf check-in: 1f80f8c1 user: dan tags: defrag-opt)

13:42
Increase the resolution of the second parameter to the likelihood() SQL function (the probability value) so that it can handle probabilities as small as 0.00000001. Formerly, it ran out of precision at 0.001. (check-in: 0f08924f user: drh tags: trunk)

Disable the use of strchrnul() unless specifically enabled by compile-time options. (check-in: e580470d user: drh tags: trunk)
19:57
Change the 0x800 bit of SQLITE_TESTCTRL_OPTIMIZATIONS so that it disables the loading of STAT3 and STAT4 content, not just the using of that content. Change the internal name of that bit to SQLITE_Stat34. (check-in: ca3b00c4 user: drh tags: trunk)

Add WHERETRACE debugging output to the whereLoopAdjustCost() routine. (check-in: ec1e942f user: drh tags: trunk)
01:05
If a skip-scan is a proper subset of some other scan, then adjust the cost of the skip-scan upward so that it is more costly than the other scan. Such a cost imbalance can arise under STAT4 because of difficulties in getting an accurate estimate for skip-scans. (check-in: f4b22a26 user: drh tags: trunk)

20:12
Use the padding word in the Mem object as temporary storage for serial_type value in OP_Record, and thus avoid a redundant computation of the serial_type for each column. (check-in: 4b3b65ee user: drh tags: trunk)
18:09

Further work on balance_nonroot(). (check-in: 6594f9b4 user: dan tags: defrag-opt)
17:42
Three small optimizations to vdbeaux.c. (check-in: 04892f8b user: drh tags: trunk)
16:02
Reduce the CPU load imposed by sqlit3VdbeCursorMoveto() by factoring out some of its functions and by avoiding unnecessary calls. (check-in: c2799aec user: drh tags: trunk)
13:00
Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose record header cache is to be cleared. This gives a small size reduction and performance increase. (check-in: 20062f49 user: drh tags: trunk)
12:30
Use OP_SorterColumns in aggregate queries. Remove OPFLAG_CLEARCACHE. (Closed-Leaf check-in: 134e65c0 user: drh tags: OP_SorterColumns)
01:23
Add the OP_SorterColumns opcode - an experiment in using a special case opcode to decode the Sorter output rather than the generic OP_Column. This might be faster. And with further work, it could eventually eliminate the need for OP_OpenPseudo. (check-in: b9c695e8 user: drh tags: OP_SorterColumns)
2014-10-12
22:37
Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining the correct cache value uses more CPU cycles than just recomputing the rowid on the occasions when it is actually needed. Replace it with the VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType when needed. Saves 100 bytes of code space and runs 0.2% faster.

Attempt to further reduce memcpy() in balance_nonroot(). (check-in: fec849dc user: dan tags: defrag-opt)
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes. (check-in: 66de1558 user: drh tags: trunk)
10:52

When using the -config option to releasetest.tcl, default the testing type to "fulltest" if it is not specified on the command line. (check-in: cf291cbe user: drh tags: trunk)
17:44
Provide the new "-config CONFIG" option to the test/releasetest.tcl script, which allows one to run a single test configuration selected by name. (check-in: d479e32b user: drh tags: trunk)
17:20
Add the estimated number of output rows to the EXPLAIN QUERY PLAN output if compiled with SQLITE_EXPLAIN_ESTIMATED_ROWS. This feature is off by default for the time being. (check-in: daa8314f user: drh tags: trunk)
15:47
Simplify the code used to generate the text for EXPLAIN QUERY PLAN. (check-in: beea1efc user: drh tags: trunk)
15:01
Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. (check-in: 68e1b4de user: drh tags: trunk)

Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. (check-in: 29304499 user: dan tags: defrag-opt)
15:08
Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. (check-in: 49dfee7c user: dan tags: trunk)
14:10
Add a test case for the memory leak fixed by the previous check-in. (check-in: bae36d54 user: drh tags: trunk)

00:07
Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. (check-in: efd87ba1 user: drh tags: stat4-avgeq)

Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. (check-in: 1f44bfdc user: drh tags: sessions)
19:51
Merge recent trunk changes (performance enhancements) into the sessions branch. (check-in: 497367cb user: drh tags: sessions)

Fix a problem with concatenating patchsets containing DELETE and INSERT operations on the same row. (check-in: 4d8537ea user: dan tags: sessions)
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 83913515 user: drh tags: trunk)

04:38
Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only. (Closed-Leaf check-in: c705cf85 user: drh tags: linear-interpolation)

2014-08-22
23:33
Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor.

Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (check-in: bdaa6947 user: drh tags: trunk)
17:25
Fix a buffer overrun in the previous commit. (Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix)
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. (check-in: 299b9570 user: dan tags: query-planner-fix)

00:29
A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8e user: drh tags: trunk)

21:03
Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (check-in: 436e8842 user: drh tags: IN-operator-improvements)

18:00
Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. (check-in: c11e55fa user: drh tags: trunk)
15:51
Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (check-in: 7c6fbcfe user: drh tags: trunk)
15:34
The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements)

Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece40 user: drh tags: trunk)
19:37
Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. (check-in: 30033f96 user: drh tags: faster-analyze)

13:40
Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers.

20:02
Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index.

19:14
The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (check-in: eed754fe user: drh tags: trunk)

2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. (check-in: f1c76c7c user: drh tags: trunk)

When sorting data for a CREATE INDEX statement in single-threaded mode, assume that keys are delivered to the sorter in primary key order. Also fix various comments that had fallen out of date. (check-in: 821d1ac4 user: dan tags: threads)
15:38
Even if compile time option SQLITE_MAX_WORKER_THREADS is set to one or greater, set the default number of worker threads to zero. Distribute data more evenly between threads in sqlite3VdbeSorterWrite() to improve performance when sorting large amounts of data. Add new test file sort2.test.

12:56
Fix a harmless compiler warning. (check-in: a4e47150 user: drh tags: trunk)
03:12
Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. (check-in: 7fa85eaa user: drh tags: trunk)
2014-03-27
19:25
Instead of allocating a single large buffer at the beginning of each sort operation, start with a small buffer and extend it using realloc() as required. (check-in: 81987c8c user: dan tags: orderby-planning)
18:36
Minor cleanup of the code in the query planner that computes the costs estimates for the various plans. There are no changes to the costs at this time. But the code is slightly more readable now and that might facilitate future enhancements. (check-in: 9b4d7226 user: drh tags: trunk)
17:23
Use xFetch() to access temporary files in vdbesort.c. Use a single large allocation instead of many small allocations when accumulating records in vdbesort.c. This is an interim commit - it allocates a buffer the size of the page-cache every time data is sorted. (check-in: f4ac1bf2 user: dan tags: orderby-planning)
14:05
Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a06 user: drh tags: trunk)

2014-03-25
20:28
Adjust the repeat counts on several tests in speedtest1 so that the relative time spent on the test is roughly the same regardless of --size. (check-in: 7922809e user: drh tags: trunk)
18:29
Merge enhancements and fixes from trunk. (check-in: e005f2d6 user: drh tags: orderby-planning)

Merge all fixes and enhancements from trunk. (check-in: b415dfb6 user: drh tags: threads)
11:00
Detect when a VdbeCursor is still pointing at a valid row but that row has moved, and invalidated the return from prior sqlite3BtreeDataFetch() or sqlite3BtreeKeyFetch() calls. (check-in: e6798871 user: drh tags: trunk)
2014-03-24
20:19
Omit the sequence value from sorter records used by GROUP BY queries that cannot use an index. (check-in: 3f90abdd user: dan tags: orderby-planning)

15:00
Fix arithmetic operators so that they do not change the affinity of their input operands. Ticket [a8a0d2996a]. (check-in: 221f8f94 user: drh tags: trunk)
12:33
Cancel column-cache entries that are involved in a comparison operator since the comparison might have forced an affinity change. Originally proposed as a fix for ticket [a8a0d2996a], but later determined to be incorrect. (Closed-Leaf check-in: 0b95b7a8 user: drh tags: tkt-a8a0d2996a)
11:23

16:29
Avoid a possible use of an uninitialized variable following an I/O or OOM error. (check-in: 641408a1 user: drh tags: trunk)
2014-03-22
02:19
Clear the sort-order flags on the KeyInfo object associated with the OP_Compare/OP_Jump of the block-sort logic, in order to make the OP_Jump fully testable. (check-in: 9b2838f2 user: drh tags: trunk)
01:52
Increase the version number to 3.8.5. (check-in: 9760879d user: drh tags: trunk)
00:27
Fix the ORDER BY optimization logic so that it will do a block-sort on a partial DESC ORDER BY. This enhancement uncovered a memory leak in pushUntoSorter() which is also fixed. (check-in: c36f7461 user: drh tags: trunk)
2014-03-21
20:58
Add the ability to use indices for the first few terms of an ORDER BY clause, then sort in batches to handle the later terms. (check-in: fa06a6fe user: drh tags: trunk)
19:56
Change the names of SRT_DistTable and SRT_Table used by CTE to more meaningful SRT_DistFifo and SRT_Fifo, respectively. Simplify the IgnorableOrderby() macro in the process. (check-in: 45d8cc67 user: drh tags: trunk)
19:27
Avoid leaking memory in an obscure case where the flattener adds an ORDER BY clause to the recursive part of a recursive query. (check-in: 1f413aca user: dan tags: trunk)
18:45
Merge the OFFSET-on-query-without-FROM fix from trunk. (check-in: 71e9ae72 user: drh tags: orderby-planning)
18:16
Fix the OFFSET clause so that it works correctly on queries that lack a FROM clause. Ticket [07d6a0453d4ed8]. (check-in: 179ef816 user: drh tags: trunk)
15:24
New test case for block-sorting. (check-in: e70cfa28 user: drh tags: orderby-planning)

20:56
Merge trunk fixes for "x IN (?)" handling. (check-in: eca35871 user: drh tags: orderby-planning)
19:04
Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. (check-in: d5a1530b user: drh tags: trunk)
18:56
Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. (check-in: d8e1f75d user: dan tags: overflow-pgno-cache)
18:45
Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. (check-in: 01944c53 user: drh tags: trunk)
17:03
The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. (check-in: 2ea4a9f7 user: drh tags: trunk)
15:14
Fix harmless compiler warnings. (check-in: b1435f26 user: drh tags: trunk)
14:56
Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] (check-in: 2ff3b25f user: drh tags: trunk)
13:26
Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. (check-in: e68b427a user: drh tags: trunk)
12:36
One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. (Closed-Leaf check-in: eae6dfbe user: drh tags: tkt-e39d0325)

Merge the vdbesort.c optimization from trunk. (check-in: e4bfffb9 user: drh tags: orderby-planning)
23:24
Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. (check-in: 01afbf97 user: drh tags: orderby-planning)
20:01
Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c (check-in: 707ea170 user: dan tags: trunk)
17:41
Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. (check-in: 7ce2daaf user: drh tags: orderby-planning)
16:56
Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. (check-in: 62f3a220 user: drh tags: orderby-planning)
15:17
Avoid reusing temporary registers in co-routines when doing block-sorting. (check-in: 463d921b user: drh tags: orderby-planning)
14:30
Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. (check-in: b186d8d1 user: drh tags: orderby-planning)
14:10
First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. (check-in: 59742dd4 user: drh tags: orderby-planning)
2014-03-18
20:33
Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. (check-in: e258df23 user: drh tags: orderby-planning)
18:59
Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. (check-in: 59d49b7f user: drh tags: orderby-planning)
15:30
Experiments with the optimization of ORDER BY and GROUP BY clauses. (check-in: b1509025 user: drh tags: orderby-planning)

Remove a stray C99-style comment. (check-in: f500e87d user: drh tags: overflow-pgno-cache)
23:40
Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. (check-in: 968fec44 user: drh tags: overflow-pgno-cache)
20:33

Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. (check-in: bc0e6610 user: drh tags: sessions)
13:48
Merge the latest 3.8.4 tweaks from trunk. (check-in: 1ed463d9 user: drh tags: sessions)

Merge in various obscure bug fixes and the removal of Mem.memType from trunk. (check-in: 0828975d user: drh tags: sessions)
14:40
When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid. The maintains legacy behavior from before the noMemType change. (check-in: 1d134ba2 user: drh tags: trunk)

04:04
Fix more instances of assuming 'char' is signed. And, make sure to never shift a signed integer. (Closed-Leaf check-in: f10130ed user: drh tags: broken-on-arm)

2014-03-03
21:59
Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create a couple of fast-track routines to handle the common cases of a string with BINARY collation or integer values as the left-most column. This gives a significant performance boost in common use. Oops: This build does not work on the Beaglebone where "char" defaults to unsigned. (check-in: aec5473a user: drh tags: broken-on-arm)
21:46
Fix a couple of harmless compiler warnings. (Closed-Leaf check-in: fcf480cc user: drh tags: experimental)

Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (check-in: e3f6c61e user: drh tags: trunk)
2014-03-01
19:45

Factor the Mem invariant checker into a separate procedure (rather than a macro) so that it can be more easily extended. (check-in: 354699d5 user: drh tags: enhanced-mem-check)
14:45
Add extra assert() statements trying to catch a Mem object in an inconsistent state. (check-in: 4aeb3ae4 user: drh tags: enhanced-mem-check)
2014-02-28
20:47
In the command-line shell add the (undocumented and unsupported) ".eqp" command and -eqp command-line option, to cause EXPLAIN QUERY PLAN to be run on each SQL statement as it is evaluated. Intended use is for analysis of the query planner. (check-in: e6ecf733 user: drh tags: trunk)

2014-02-26
21:35
More efficient removal of duplicates in recursive queries using the UNION compound operator. (check-in: 06c2db87 user: drh tags: trunk)
19:05
Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch. (Leaf check-in: 3ad687b7 user: drh tags: open-only-once)
13:53
In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. (check-in: 9c2e7612 user: drh tags: trunk)

Improved handling of constants and especially constant functions in the ORDER BY clause of a query. Do not optimize out "ORDER BY random()". Fix for ticket [65bdeb9739605cc2296]. (check-in: dca1945a user: drh tags: trunk)
2014-02-25
21:55
Do not allow temporary registers to be in use across an OP_Yield within a co-routine. Fix for ticket [8c63ff0eca81a9132d8]. (check-in: 97a8c973 user: drh tags: trunk)
21:01
Attempt to speed up sqlite3VdbeRecordCompare() by various means. This code is in an interim state. (check-in: 85206e0b user: dan tags: experimental)
19:38
Make sure temporary registers used within a co-routine are not also used outside of that co-routine, in order to prevent concurrent use of the same register for two different things. Ticket [8c63ff0eca81a9132d8] (Closed-Leaf check-in: cc5eda54 user: drh tags: tkt-8c63ff0eca)
18:12
Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. (check-in: 23001a85 user: drh tags: trunk)
14:52
QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. (check-in: 953cdd6a user: drh tags: trunk)

Enhance testing support for the Win32 VFS dynamic extension loading facilities. (check-in: 53081e72 user: mistachkin tags: trunk)
19:49
Close some stray connections in walro.test. (check-in: d6746cab user: dan tags: trunk)
19:07
In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. (check-in: ba5f0a55 user: drh tags: trunk)
14:24
Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. (check-in: 4df0ac90 user: drh tags: trunk)
2014-02-21
10:48
Merge updates from trunk. (check-in: 09cf240a user: mistachkin tags: winHdr)

Fix the text of a comment used to generate VDBE opcode documentation so that it omits symbols that can be mistaken for a hyperlink by the parser. (check-in: b46d4e89 user: drh tags: trunk)
19:32
Fix a harmless shadowed-variable warning. (check-in: 82402909 user: drh tags: trunk)

2014-02-19
19:14
Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. (check-in: c1e94169 user: drh tags: trunk)
14:20
Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f3 user: drh tags: trunk)
01:31
Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cf user: drh tags: trunk)

Enhance the Win32 VFS I/O retry logic. (check-in: adba783c user: mistachkin tags: winIoRetry)
03:07
Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a9 user: drh tags: trunk)
01:07
Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. (check-in: 915f6f1c user: drh tags: trunk)
2014-02-17
23:52
Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. (check-in: a7268769 user: drh tags: trunk)

Merge the VDBE_PROFILE fixes from trunk. (check-in: 2914e419 user: drh tags: insert-optimization)
14:59
Avoid unnecessary calls to applyAffinity() during INSERT and UPDATE operations, especially for table that have indices and tables for which all columns have affinity "NONE". (check-in: 35b4d6e9 user: drh tags: insert-optimization)
01:13
Fix the VDBE_PROFILE logic. Add a script to process the output file. (check-in: 7adb3da2 user: drh tags: trunk)
2014-02-16
19:20
Use the modern MinGW major version macro, not the deprecated one. (Closed-Leaf check-in: 057c16ee user: mistachkin tags: mingw4x)
01:55
Enhance the code generator for INSERT INTO ... SELECT so that the SELECT generates output directly in the registers that INSERT INTO will be using, in many cases, and OP_SCopy operations can thus be avoided. (check-in: aa2d8b0e user: drh tags: insert-optimization)

Better support for MinGW 4.x. (check-in: e1472307 user: mistachkin tags: mingw4x)
20:59
Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. (check-in: 3c1ae447 user: drh tags: trunk)
15:13
Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where done using OP_IdxGE and OP_IdxLT with the P5 flag set. But VDBE code is easier to read with distinct opcode names. Also change OP_SeekGe to OP_SeekGE, and so forth, so that the capitalization is consistent. The whole point of this change is to improve the readability of VDBE listings. (check-in: b6bea903 user: drh tags: trunk)
00:25
Revise how the Tcl system encoding is handled by the test suite. (check-in: 9e573198 user: mistachkin tags: trunk)

Improvements to the makefile and README for MSVC. (check-in: b22b6140 user: mistachkin tags: trunk)
19:27
Ensure that if the "psow=0" URI option or FCNTL_POWERSAFE_OVERWRITE file-control is used to clear the power-safe overwrite flag, extra padding frames are added to the WAL file. (check-in: 48c821fd user: dan tags: trunk)
19:10
Change README to README.md and expand it. Remove unrelated and obsolete files. (check-in: 18d4e258 user: drh tags: trunk)

Minor simplifications to the "zeroPage()" routine in btree.c. (check-in: cc8f10bc user: drh tags: trunk)
21:31
Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. (check-in: 56bc5ce8 user: drh tags: trunk)
15:05
Various fixes and test case updates so that veryquick.test passes again. (Leaf check-in: f352ef57 user: dan tags: deferred-open)

Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea97 user: drh tags: trunk)
2014-02-07
22:21
Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7 user: drh tags: trunk)

In the Win32 VFS, the winSysInfo variable should be static. (check-in: 4a4dd371 user: mistachkin tags: trunk)
2014-02-04
23:45
Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. (check-in: f2504089 user: drh tags: trunk)

2014-01-21
22:25
Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. (check-in: b2671e11 user: drh tags: cte-via-queue)

00:19
Add support for the LEVEL pseudo-column in the recursive part of a common table expression. LEVEL has the value of 1 on the first iteration and successively larger integer values of subsequent iterations. It cannot have a table qualifier. Actual columns named "level" can still be accessed by including the table name qualifier. (check-in: cc1cb321 user: drh tags: level-pseudocolumn)
2014-01-20

15:27
Fix a compiler warning in selectPopWith(). (check-in: c8eb1163 user: drh tags: trunk)

Allow only a single recursive reference in a recursive CTE. Also require that this reference is not part of a sub-query. (check-in: a296b733 user: dan tags: common-table-expr)
15:31
Always use available indices to optimize LIKE operators even if the pattern of the LIKE operator has a COLLATE modifier. This fixes an ineffiency that was introduced into 3.7.15 by check-in [8542e6180d4] on 2012-12-08. (check-in: 16bd5478 user: drh tags: trunk)
10:58
Disable the flattening optimization if the parent query is the recursive part of a recursive CTE and the sub-query is a compound query. (check-in: 6bfa387e user: dan tags: common-table-expr)

18:12
When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context. This ensures that correlated sub-queries are correctly identified as such. (check-in: 61be2da0 user: dan tags: common-table-expr)

Add the "%token_class" directive to the LEMON parser generator. This opens up the possibility of simplifying the parser. Also remove all calls to sprintf(), strcpy(), and strcat() from LEMON to avoid compiler warnings on OpenBSD. (Aside: It is this change to avoid harmless compiler warnings that was the cause of the reason spat of bugs.) (check-in: 8eb48c04 user: drh tags: trunk)

Fix harmless compiler warnings in FTS4. This involved corrupting Martin Porter's beautifully written and elegant stemmer code, making it a little less beautiful and a little less elegant. Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. (check-in: df056798 user: drh tags: trunk)

Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed.

Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs.

04:22
Lower the threshold for using skip-scan from 50 to 18, based on experiments that show that 18 is the approximate break-even point for a variety of schemas. (check-in: 83c0bb99 user: drh tags: trunk)
04:00
Avoid using the GetVersionEx functions if they are considered deprecated. (check-in: afdca299 user: mistachkin tags: trunk)
03:01
Avoid using the GetVersionEx functions if they are considered deprecated. (Closed-Leaf check-in: 0ea9e472 user: mistachkin tags: vs2013)
01:23
Add additional test cases for skip-scan. (check-in: 1ae4915d user: drh tags: trunk)
00:45
Add additional test cases and requirements evidence marks for WITHOUT ROWID. (check-in: b408d788 user: drh tags: trunk)
2013-11-26
23:27
Make sure the update hook is not invoked for WITHOUT ROWID tables, as the documentation specifies. This bug was found while adding requirements marks, so a few extraneous requirements marks are included in this check-in. (check-in: 0978bac6 user: drh tags: trunk)
22:46
Add requirements test cases for determining when an expression is true and when it is false. (check-in: 838654e5 user: drh tags: trunk)
21:18
Changing the CAST behavior of REAL values actually changed a documented requirement. So we also have to change the requirement evidence text to match. (check-in: d84aa44e user: drh tags: trunk)

16:20
Do not try to run the atof1.test test script on ARM hardware which lacks the "long double" type. (check-in: fafca560 user: drh tags: trunk)
15:45
Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works. (check-in: 6f53fc71 user: drh tags: trunk)
01:13
Fix comment. (check-in: 8364af39 user: mistachkin tags: winHdr)

22:24
Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. (check-in: 011a6be4 user: drh tags: trunk)
21:49
Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. (Closed-Leaf check-in: 51e87607 user: mistachkin tags: winHeapSize)
21:41
Remove a NEVER() from a branch that is now reachable during OOM faults. (check-in: 18bdcb05 user: drh tags: trunk)
20:50
Optimizations to the sqlite3BtreeMovetoUnpacked() routine in storage engine making it about 17.8% faster, which in turn makes SQLite over 1.2% faster overall. (check-in: 032e8993 user: drh tags: trunk)
20:14
Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. (Closed-Leaf check-in: b48c4e40 user: drh tags: btree-optimization)
17:38
Uses shifts rather than division for arithmetic on the cell indices, since those indices are always non-negative. (check-in: 5bf2a3fe user: drh tags: btree-optimization)
16:52
Optimize the skipping of the payload size field when doing a binary search for a rowid. (check-in: 55e5bfa2 user: drh tags: btree-optimization)
16:23
Arrange for sqlite3BtreeMovetoUnpacked() to always leave the cursor cell parse cache invalidated. This fixes issues with previous check-ins on this branch and also runs faster. (check-in: a7467560 user: drh tags: btree-optimization)
15:01
More optimizations to sqlite3BtreeMovetoUnpacked(). But there are failures in TH3. Committing this intermediate state to facilitate bisecting. (check-in: f80497be user: drh tags: btree-optimization)
14:10
More improvements to sqlite3BtreeMovetoUnpacked() performance. (check-in: 88680698 user: drh tags: btree-optimization)
09:37
Correct line-endings in the new header file. (check-in: 94219b9f user: mistachkin tags: winHdr)

01:14
Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. (check-in: 8f3c767a user: drh tags: trunk)
00:46
The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. (check-in: 12e612e8 user: drh tags: trunk)
2013-11-23
22:45
A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. (Closed-Leaf check-in: 8191b512 user: drh tags: memsys5-performance)
21:30
Use a heap-based primary queue rather than a linked list to store the available free blocks of each size in MEMSYS5, since this provides faster access to the first available block. (Closed-Leaf check-in: 7d2cdfad user: drh tags: memsys5-performance)
21:29
Add newlines at the end of some error messages in speedtest1. (check-in: 6b98f0af user: drh tags: trunk)

21:59
Changes some offset and amount parameters from "int" to "u32" to avoid harmless signed/unsigned comparison warnings. (check-in: 4e8c5d07 user: drh tags: trunk)
21:40
Modify wordcount so that timer information appears on standard error instead of standard output. Rename the run-wordcount.bash script to run-wordcount.sh and simplify it so that it stands a better chance of running on non-GNU systems. (check-in: 586c11ed user: drh tags: trunk)
21:23
Do not reuse factored constants that might have had their encodings changed. (check-in: 487f2036 user: drh tags: trunk)

19:34
Change the "idx" name of the primary key index for WITHOUT ROWID tables in sqlite_statN statistics tables to be the name of the table rather than the fabricated index name (ex: sqlite_autoindex_xyz_1).

2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)
14:28
Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. (check-in: 5ca0ea2e user: drh tags: omit-rowid)
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. (check-in: 824b549f user: drh tags: omit-rowid)
