671 check-ins using file src/global.c version 0dea3065ea

2024-09-18
18:04
Improvements to the scope of valueFromFunction(). (Leaf check-in: b021399a6e user: drh tags: branch-3.28)
2024-06-07
00:20
Allow the query planner access to the argument of LIMIT even if that argument is a bound parameter. (check-in: 148d505ca0 user: drh tags: branch-3.28)
2024-06-06
16:06
Better optimize queries that use parameters in the LIMIT clause. (Closed-Leaf check-in: b44f267671 user: drh tags: branch-3.28-var-in-limit)
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. (check-in: 357d9513d2 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: 1f97086d62 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: 74b247d958 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: f10d4fc4a8 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: f9c6e6a710 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: d4bfa8d21a 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: 796a65fa61 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: 83a7f13edb 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: ad6ac5d3e8 user: drh tags: branch-3.28)
19:04
Back-port omit-unused-subquery-column enhancements into the 3.28 branch. (check-in: 57a4e91f43 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: 0163b697dd user: drh tags: branch-3.28)
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: 3d1992de47 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: 3da1032878 user: drh tags: branch-3.28)
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: e3754cc188 user: drh tags: branch-3.28)
2022-08-10
17:03
Merge the branch-3.28a fixes into branch-3.28. (check-in: ba6bf33147 user: drh tags: branch-3.28)
2022-08-09
20:22
Fix a rounding error caused by scalar->logarithm->scalar conversion when using stat4 data to estimate some range scans. (check-in: 68d86f2b20 user: drh tags: branch-3.28)
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: d2e6722037 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: 9e001b635f 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: 263293f1e6 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: c144d6404f 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: ec37744c6e 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: 9a1cdf7e9c 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: f07ac3fb38 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: 49b7631e86 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: 8301da31d0 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: 0ecda43371 user: dan tags: branch-3.28)
2020-05-06
18:46
Provide the SQLITE_DEFAULT_LEGACY_ALTER_TABLE compile-time option. (check-in: b2325a6e1c user: drh tags: branch-3.28)
2020-01-17
15:33
More restrictions on changes to shadow tables when in defensive mode. (check-in: b302b260ca user: drh tags: branch-3.28)
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: 3d13fbf248 user: drh tags: branch-3.28)
14:56
Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f16 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: be4269c624 user: drh tags: branch-3.28)
2019-07-18
20:55
Fix a problem where self-joins on views that are aggregate queries may return the wrong result. Cherrypick of [74ef97bf51dd531a]. (check-in: 2f0a564f6e user: mistachkin tags: branch-3.28)
2019-06-14
13:24
Fix the implementation of the built-in RTRIM collating sequence so that it works for control characters at the end of the string. Ticket [f1580ba1b574e9e9] (check-in: 86fa0087cd user: drh tags: trunk)
12:28
Refactor the LIKE optimization decision logic so that it uses sqlite3AtoF() on both boundary keys to determine if the optimization can be used when the LHS is something that might not have TEXT affinity. Ticket [ce8717f0885af975]. See also [c94369cae9b561b1], [b043a54c3de54b28], [fd76310a5e843e07], and [158290c0abafde67]. (check-in: b4a9e09e60 user: drh tags: trunk)
2019-06-13
16:14
Add a new requirement mark on the ctime.c code. (check-in: c4b405687b user: drh tags: trunk)
14:07
Do not use the %lld printf conversion in the platform printf() as some legacy platforms do not support it. (check-in: f8696b60ee user: drh tags: trunk)
13:52
Fix a minor error in a test script, and harmless compiler warnings in the CLI code. (check-in: eaa34626e4 user: drh tags: trunk)
2019-06-12
22:46
Adjust requirements marks and add new requirements tests. (check-in: ebb81dad1f user: drh tags: trunk)
20:51
As a special case, casting '-0.0' into numeric should yield 0. Fix for ticket [674385aeba91c774]. (check-in: 491f0f9bbd user: drh tags: trunk)
20:11
Enhancements to the printf() logic in order to render a negative zero with a minus sign. (Leaf check-in: 6ba4be66be user: drh tags: negative-zero)
13:49
Handle expressions like "expr IS TRUE COLLATE xyz" in the same way as "expr IS TRUE". Fix for [4d01eda8115b10d1]. (check-in: 5c6146b56a user: dan tags: trunk)
2019-06-11
21:02
The affinity of the unlikely() function and its cousins should be "none". Ticket [0c620df60bffd9ef] (check-in: 614ecb0af4 user: drh tags: trunk)
18:07
Make sure the affinity of the RHS of an IN operator does not affect the outcome even if the RHS expression contains a COLLATE clause. Ticket [57353f8243c637c0] (check-in: 0f748fe58b user: drh tags: trunk)
16:43
Mark an unreachable branch with an ALWAYS macro. (check-in: d4755aca4b user: drh tags: trunk)

Off-by-one error in the CAST to NUMERIC logic. (check-in: 25b8963020 user: drh tags: trunk)
12:03
Have the ALTER TABLE code handle the case where an entire expression that includes a sub-select is excluded from a view, trigger or index. (check-in: f2c8179f3c user: dan tags: trunk)
10:43
Add the new sqlite3ExprUnmapAndDelete() function and use it in place of separate calls to sqlite3RenameExprUnmap() and sqlite3ExprDelete(). (check-in: 36ea13e0a8 user: drh tags: trunk)
02:43
The ALTER TABLE command should not attempt to rename objects that are contained within an expression tree that has been optimized out because it is the other branch of an "AND false" expression. Ticket [533010b8cacebe82] (check-in: 04bd5cb732 user: drh tags: trunk)
01:56
Fix repeated test numbers in the altertab2.test file. (check-in: e82f235e72 user: drh tags: trunk)
01:30

2019-06-10
23:45
A string consisting of a single '.' is not a floating point literal with extra text at the end. Fix for ticket [412bba9b22c677da] (check-in: 5705016229 user: drh tags: trunk)
19:17
Have ALTER TABLE commands ignore the lhs of "expr IN ()" and "expr NOT IN ()" expressions, just as other queries do. Fix for [533010b8ca]. (check-in: 71643deb6b user: dan tags: trunk)
19:07
Improvements to the documentation for the xAccess method of the VFS. Ticket [5e0423b058fa5adf] (check-in: 7078d77eff user: drh tags: trunk)
18:33
Make sure a CAST to "NUMERIC" results in an integer if the value can be losslessly expressed as an integer, as the documentation requires. Ticket [dd6bffbfb6e61db9]. (check-in: c0c90961b4 user: drh tags: trunk)
15:34
Handle renaming a column or table when the schema contains a (meaningless) index on the constant expression ('text' IN ()) or ('text' NOT IN()). Fix for [fd76310a]. (check-in: 567b130939 user: dan tags: trunk)
13:46
Do not attempt the LIKE optimization on a column with numeric affinity if the rhs of the operator begins with whitespace. Fix for ticket [fd76310a5e]. (check-in: 94b58ab059 user: dan tags: trunk)
2019-06-07
22:51
Remove code in the round() SQL function that became unreachable due to the optimization of check-in [e95138f5f4febde5] (check-in: b141bae3f6 user: drh tags: trunk)
22:26
When casting string values into numeric and the string has a prefix that looks like a number but total string is not a well-formed number, then take extra care that the result is either integer or real depending on what the prefix looks like. Fix for tickets [e8bedb2a184001] and [4c2d7639f076aa]. (check-in: 67a68af557 user: drh tags: trunk)
18:56
Also upgrade script config.sub to the latest version. This should have been part of the previous commit. (check-in: efbf31b82e user: dan tags: trunk)
18:53
Upgrade the config.guess script to the latest version. (check-in: be8438133f user: dan tags: trunk)
2019-06-05
14:29
CLI enhancements: Add the ".filectrl" command. Make the ".testctrl" command visible to ".help". (check-in: 7b3a99fce8 user: drh tags: trunk)

15:10
Fix harmless compiler warning in lemon. (check-in: 3a05242953 user: mistachkin tags: branch-3.28)
15:09
Fix harmless compiler warning in lemon. (check-in: 2da0eea02d user: mistachkin tags: trunk)
14:02
Updates to the shared_schema.md notes document. (check-in: 51af2ade8e user: drh tags: reuse-schema)
13:53
Fix the count-of-view optimization so that it is (correctly) disabled for a query that includes a WHERE clause or a GROUP BY clause. Cherrypick of [05897ca48a40c6771]. (check-in: 583e5a0ab6 user: mistachkin tags: branch-3.28)
13:46
In the CLI, add ".help" text for the .shared-schema command. (check-in: 3ba6f790e0 user: drh tags: reuse-schema)
2019-05-30
13:47
Optimization to the round() SQL function for large input values without a fractional part. (check-in: e95138f5f4 user: drh tags: trunk)
00:46
Smaller and faster sqlite3IsNaN() implementation makes deserialization of floating point values much faster. (check-in: ea748edecb user: drh tags: trunk)
2019-05-29
21:18
Much faster implementation of applyNumericAffinity() by avoiding some unnecessary calls to sqlite3Atoi64(). (check-in: c1d8a3f654 user: drh tags: trunk)
18:33
Add an assert() as an additional test for fix in check-in [523b42371122d9e1b3]. (check-in: f9e85e6c79 user: drh tags: trunk)
17:22
Fix the query flattener optimization so that it preserve the "SF_Compound" bit when flattening a compound subquery into a non-compound outer query. Failure to preserve that bit could allow subsequent flattenings which are not valid. Fix for ticket [c41afac34f15781fe09cd]. (check-in: 523b423711 user: drh tags: trunk)
2019-05-28

2019-05-27
11:21
Fix an error message on the blobread() extension function so that it says "read" instead of "write". (check-in: 7cbb9a5fe8 user: drh tags: trunk)
11:09
Fix a memory leak in the delta_parse() table-valued function of the fossildelta.c extension. (check-in: c86ca3f022 user: drh tags: trunk)
00:29
Improved rounding even on systems with an 8-byte "long double" type. (check-in: 15202aee15 user: drh tags: trunk)
2019-05-25
18:17

2019-05-24
22:58
Improvements to rounding behavior in the round() and printf() functions. (check-in: 641b2d2105 user: drh tags: trunk)
13:15
The ".shared-schema" command in the CLI requires the sqlite_dbpage table, so disable it if the build does not include that extension. (check-in: 0913ff4dc3 user: drh tags: reuse-schema)
13:04
Merge recent enhancements from trunk. (check-in: ff9f3e0951 user: drh tags: reuse-schema)
11:55
Fix an fts5 segfault that could occur after parsing a corrupt structure record. (check-in: 600daa9c27 user: dan tags: trunk)
2019-05-23
16:40
Add test cases for the fix in the previous commit. (check-in: c1057b2a60 user: dan tags: trunk)
16:38
Improvements to the view-self-join optimization so that it works on all VIEWs, not just on Common Table Expressions. (check-in: d2fe370caf user: drh tags: trunk)
2019-05-22
23:12
New test case for check-in [74ef97bf51dd531a] that takes the fix in the previous check-in into account. (check-in: cb1d06521d user: drh tags: trunk)
22:49
Renumber the Select.selId values in the copies of SELECT statements that implement VIEWs when the VIEW is expanded, so that when the same VIEW is used twice in the same join, each expansion as a distinct selId. This fixes ticket [ce823231949d3abf42453c8]. (check-in: 3cacc4b940 user: drh tags: trunk)
14:35
New dbsqlfuzz find added to test/fuzzdata8.db. (check-in: 42af7c819b user: drh tags: trunk)
14:22
Fix a buffer overread that could in fts3 when dealing with corrupt records. (check-in: 1660d7733e user: dan tags: trunk)
2019-05-21
17:04
Combine the implementations of the key and hexkey pragmas into a single case. Have both pragmas return "ok" if they are implemented. (check-in: b3692c406f user: drh tags: trunk)
16:32
Fix a problem in [b5ca442a] causing an assert() to fail in REINDEX commands. (check-in: a3e77c7776 user: dan tags: trunk)
14:42
Use a statement journal for all CREATE INDEX statements in case an indexed exprsesion throws an exception when it is evaluated. Fix for [b5ca442a]. (check-in: b8071d10cb user: dan tags: trunk)
2019-05-20
19:46
Fix a segfault that could occur in sqlite3session_diff() if NULL were passed as the pzErrMsg argument. (check-in: aee73fd28f user: dan tags: trunk)
18:43
Improvements to the automatic compile-time selection of byte-order, as suggested on the mailing list by Seb Kemper. (check-in: b7aad92961 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: 3e1b55f3ab user: drh tags: trunk)
17:14
Disallow string constants enclosed in double-quotes within new CREATE TABLE and CREATE INDEX statements. It is still possible to enclose column names in double-quotes, and existing database schemas that use double-quotes for strings can still be loaded. This addresses ticket [9b78184b]. (check-in: 1685610ef8 user: dan tags: trunk)
10:36
Update the sqlite3ExprCompare() routine so that it does not think "? IS NOT TRUE" is the same as "? IS TRUE". Fix for [d3e7f2ba5b3]. (check-in: 99eba69b3a user: dan tags: trunk)
2019-05-18
21:22
Fix an assert() failure that could occur in a join query if the RHS of an IN() operator is a list containing correlated expressions. This problem was introduced by checkin [e130319317e7611938] which was part of the fix for ticket [787fa716be3a7f650c] - so this commit is part of that ticket's fix too. (check-in: 778b1224a3 user: dan tags: trunk)
19:49
Avoid including the comment in the output of "PRAGMA table_info" in situations where there is a comment following a DEFAULT value within a CREATE TABLE statement. (check-in: d91095ba71 user: dan 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.

Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0bc9 user: drh tags: trunk)
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. (check-in: d272819298 user: drh tags: trunk)

14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb43f user: drh tags: trunk)
14:00
Only preserve rowid values for VACUUM INTO. Keep the legacy behavior of renumbering rowids for ordinary VACUUM. (check-in: 13a0ea6466 user: drh tags: trunk)

17:45
Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c324 user: drh tags: trunk)
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. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. (check-in: 10aedce3dd user: drh tags: trunk)

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: f7ba2daf91 user: drh tags: trunk)

18:39
The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd338 user: drh tags: trunk)
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56da4 user: drh tags: trunk)

Fix an obsolete comment in the CLI. No code changes. (check-in: fade103cba 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: e775ef002d 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: 9b20ee10ff 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: 24ef384469 user: drh tags: trunk)
19:50
Earlier detection of corruption while added to the freelist. (check-in: 8c80b004ca 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: bcbe7d96df user: drh tags: trunk)
15:09
Improvements to the help text in the CLI. (check-in: 919fec91da 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: f11c89595d 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: 191a023ae7 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: 7a0a26ed38 user: drh tags: trunk)
11:38

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: 9ef69d1839 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: a420ebd08f 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: c02f77b1b4 user: dan tags: window-functions)

Fix a harmless compiler warning that only comes up during debug builds. (check-in: 848869ced9 user: drh tags: trunk)
15:43
Add the ".shared-schema check|fix DB1 DB2..." command to the shell tool. For checking if a database is eligible to share an in-memory with the main database, and for fixing small problems that prevent it from being so. (check-in: 7d8e8a9572 user: dan tags: reuse-schema)
12:29
Update the configure-generated makekfile to generate a portable pkgIndex.tcl. (check-in: 35cbee7fe4 user: drh tags: trunk)

Enhance the command-line shell to accept bound parameters, using the TEMP table named "$Parameters" to look up the values for bound parameters. (check-in: 7c941ce5bc user: drh tags: trunk)
18:07
Merge latest trunk changes into this branch. (check-in: 5c1cf30859 user: dan tags: reuse-schema)
17:54
Where possible, avoid loading all schemas into memory for PRAGMA statements. (check-in: 64f97530ad user: dan tags: reuse-schema)
16:06
Version 3.27.2 (check-in: bd49a8271d user: drh tags: release, branch-3.27, version-3.27.2)
15:55
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. (check-in: a21ffcd817 user: drh tags: branch-3.27)
15:43
This was originally intended to be the 3.27.2 release, but then I realized that I left out an important patch. (Closed-Leaf check-in: 6c5e5e2ee0 user: drh tags: mistake)
14:52
Update comments on the fossildelta extension. No changes to code. (check-in: 9da4fb59b2 user: drh tags: trunk)

Fix a typo in the documentation for sqlite3_total_changes(). (check-in: 8474c1560e user: drh tags: trunk)
2019-02-23
20:48
Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af521 user: dan tags: trunk)
00:56
Import from trunk the new fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: 0e64ac122a user: drh tags: branch-3.27)
00:21
Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: d3915230e3 user: drh tags: trunk)
00:08
Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. (Closed-Leaf check-in: 90c5a17cd5 user: drh tags: tkt-df46dfb631)
2019-02-22
23:29
Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. (check-in: c2d50df8fd user: drh tags: tkt-df46dfb631)
21:33
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: 0d456456da 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: 579b66eaa0 user: dan tags: trunk)
17:44
Merge latest trunk changes into this branch. (check-in: 001771afd0 user: dan tags: reuse-schema)
16:18
In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. (check-in: 73056b314b 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: e7144ffd21 user: drh tags: trunk)
2019-02-21
18:11
Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c17 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: c13d563925 user: drh tags: trunk)
2019-02-20
19:20
Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. (check-in: be21a6416d user: drh tags: trunk)
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. (check-in: af84774d1e user: drh tags: trunk)

Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042f4 user: dan tags: reuse-schema)
18:13
Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. (check-in: c48f6f39c5 user: drh tags: trunk)
17:36
Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. (check-in: 9a78d89c84 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: 0c5db18d79 user: drh tags: trunk)
13:23
Merge the latest performance enhancements and fixes from trunk. (check-in: be71d1e24c user: drh tags: apple-osx)
13:14
Increment the version number to 3.27.2. (check-in: a70d67d8af 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: 55e38d53ad 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: fa792714ae 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: b5f90bfe62 user: drh tags: tkt-df46dfb631)

Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. (check-in: b80cafa6f8 user: drh tags: trunk)
18:00
Improve error messages caused by corrupt database schemas in OPEN_SHARED_SCHEMA mode. (check-in: 8ac75b8a88 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: 12517d1b15 user: drh tags: trunk)
16:42
Fix an assert() that might not be true if the database file is corrupt. (check-in: f2d400db4d user: drh tags: trunk)

New assert() to verify the TF_HasprimaryKey flag. (check-in: 0abace8a7a user: drh tags: trunk)
13:08
Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. (check-in: 55d43adc89 user: drh tags: trunk)
2019-02-18
18:16
Ensure that creating temp schema items does not cause an OPEN_SHARABLE_SCHEMA connection to load all schemas into memory. (check-in: 88cbf54eee user: dan tags: reuse-schema)
12:16
Fix an assert() that might not be true if the %_segdir table of FTS3 contains corrupt entries. (check-in: a6509ca3dc user: drh tags: trunk)

2019-02-15
19:36
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: cb236cb985 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: ecf6251ec0 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: 03c4f00317 user: dan tags: reuse-schema)
2019-02-14
21:04
Fix SQLITE_DBSTATUS_SCHEMA_USED so that it works with SQLITE_OPEN_SHARED_SCHEMA connections. (check-in: d43b3c056c user: dan tags: reuse-schema)

Fix a problem with OPEN_REUSE_SCHEMA connections reloading the temp schema. (check-in: 7c2ec2d4cf user: dan tags: reuse-schema)
2019-02-12
22:58
Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. (check-in: 167b91df77 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: 68cce272e7 user: drh tags: trunk)
20:58
Add tests for creating temp schema objects with SQLITE_OPEN_REUSE_SCHEMA connections. (check-in: 8c07b609fc user: dan tags: reuse-schema)

Build and test fixes for SQLITE_OMIT_WINDOWFUNC builds. (check-in: 8824115a97 user: dan tags: trunk)
11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. (check-in: 4a4952d38e user: dan tags: trunk)
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. (check-in: 7b41222428 user: drh tags: trunk)

Fix a page-cache reference leak in the btree balancer when there is a corrupt database. (check-in: 9285899120 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: 1d43ee4000 user: drh tags: deferred-free-space)
19:23
Change a few assert() statements in fts3 that might fail if the database is corrupt. (check-in: db74a56af7 user: dan tags: trunk)

Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d21295707 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: 5c499da8a4 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: 0cdae60ed7 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: 5c6638040b user: drh tags: trunk)

Increase the version number to 3.27.1. (check-in: b94d5428bb 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: 440a7cda00 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: 3087a0c31e user: drh tags: trunk)
00:55
If the query flattener detects an error, cause the SELECT code generator to abort immediately. (check-in: 3d3b142f10 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: 9dbf512d1c 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: 4d0a949fd9 user: drh tags: trunk)

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: 1aee70d6de 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: 179e5d4605 user: drh tags: trunk)
18:46
Performance improvement in the parsing of options to %-formats in the printf implementation. (check-in: 40d8f8ae87 user: drh tags: trunk)
