2021-08-11
18:56
Fix an RBU problem with restarting an update after the *-oal file is already larger than 4GiB. (Leaf check-in: 56869f54 user: dan tags: rbu-replace-hack)
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. (Leaf check-in: d2e67220 user: dan tags: branch-3.28a)
2021-07-12
15:00
Fix a defect in the query-flattener optimization identified by ticket [8f157e8010b22af0]. This fix is associated with CVE-2020-15358. (Leaf check-in: bcd014c4 user: dan tags: branch-3.32a)
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)
2021-02-11
16:19
In RBU, avoid passing VFS xShmLock calls through to the underlying VFS in cases where xShmMap calls may not be. This fixes a bad interaction with ZipVFS. (Leaf check-in: 0c3838d9 user: dan tags: reuse-schema-3.31)
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. (Leaf 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)
2020-07-24
09:14
Fix pointer aliasing problem in the in-memory journal code. Ref: forum post d44eb2fc44 (check-in: 892e9191 user: drh tags: trunk)
2020-07-23
20:37

2020-07-20
23:33
Fix the ".read" command so that it gives an error when its argument is a directory. See forum message 4c53c434ca. (check-in: 6d258c3c user: drh tags: trunk)

Redesign for better legacy compatibility. Add the sqlite3_uri_key() interface. (check-in: bcb43d11 user: drh tags: enhanced-uri)
2020-01-10
18:05
Rearchitect the way in which filenames are stored in the Pager object so that the sqlite3_uri_parameter() interface will work from journal and WAL filenames too. This check-in implements the central idea, and compile and runs somewhat, but crashes on an extended test. (check-in: 2ae77bd2 user: drh tags: enhanced-uri)
01:05
Fix to the register validity tracking logic in debug builds. No impact on release builds. (check-in: 0a500da6 user: drh tags: trunk)
00:20
Begin making changes to turn off trusted schema in command-line tools that open SQLite databases. There are a lot of these, and a lot of places to change, which makes me wonder if trusted schema should be off by default. (Leaf check-in: 3d23a275 user: drh tags: default-untrusted-schema)
00:00
Documentation updates on newer APIs. No changes to code. (check-in: 8845a8c2 user: drh tags: trunk)

Fix a problem that restricted edgy functions in TEMP tables. New test cases added. (check-in: 8878c407 user: drh tags: new-security-options)
2020-01-08
22:22
Block edgy functions used in DEFAULT constraints. (check-in: da434dc1 user: drh tags: new-security-options)
20:37
Performance improvements and test cases added. Allow "PRAGMA trusted_schema=ON" (check-in: 30882ca8 user: drh tags: new-security-options)
17:28
Check for whether or not it is safe to use non-innocuous functions as the function is being coded, not when its name is resolved. (check-in: 1da802d5 user: drh tags: new-security-options)
15:44
Provide the -innocuous option to the "db func" method in the TCL interface. (check-in: 0138652b user: drh tags: new-security-options)
15:43
Fix the rot13.c extension to be deterministic. Add the noop.c extension. (check-in: a679122c user: drh tags: new-security-options)
14:39
In the TreeView debugging output, show a "DDL" mark on SrcList and Expr nodes that derive from a non-TEMP schema. (check-in: fe7472fd user: drh tags: new-security-options)
13:08
Merge recent changes from trunk. (check-in: 5962921f user: drh tags: new-security-options)
12:17
When doing a text-to-double conversion on a BLOB with an odd number of bytes and assuming a UTF16 encoding, ignore the last byte. Ticket [9eda2697f5cc1aba]. (check-in: 1c76f1d8 user: drh tags: trunk)
11:36
Fix a minor formatting error in the display of BLOB values during VDBE tracing. (check-in: 29544288 user: drh tags: trunk)
10:57
Improvements to the documentation of sqlite3_create_collation(). (check-in: fa866aec user: drh tags: trunk)
04:36
Simplification of the logic in the constant-propagation optimization. (check-in: 1c3e5c20 user: drh tags: trunk)
01:43
Fix the constant propagation optimization so that it does not try to propagate constant expressions that have affinity. Ticket [82ac75ba0093e5dc] (check-in: 6db1c349 user: drh tags: trunk)
00:39
Fix a misworded comment. No code changes. (check-in: ee0bc7ed user: drh tags: trunk)
2020-01-07
19:45
Create the "trusted_schema" pragma. Add sqlite3_vtab_config() calls to set the risk rank for many virtual tables. (check-in: 4c21373c user: drh tags: new-security-options)
18:10
Enforce SQLITE_VTABRISK restrictions. (check-in: 3d87ff31 user: drh tags: new-security-options)

13:32
Add an "|| CORRUPT_DB" term to an assert() statement inside of btree. (check-in: 03c1d75d user: drh tags: trunk)
09:06
Fix an instance of an undefined behaviour (a left-shift of a 64-bit unsigned integer by a value greater than 64) that could occur in fts3. (check-in: e1f12978 user: dan tags: trunk)
2020-01-06
20:48
In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. (check-in: e1154c39 user: drh tags: trunk)
19:30
Merge enhancements from trunk. (check-in: 9c50f6c2 user: drh tags: new-security-options)
19:23
Rewrite the (debugging use only) sqlite3VdbeMemPrettyPrint() function to use the safer StrAccum interface rather than writing directly into a static string buffer. Perhaps this will address ticket [bbd55a97e66ff50d], which we are unable to reproduce. (check-in: 69f6a7e4 user: drh tags: trunk)
18:59
Backout change [4d0b9109f7a5312d4e1] because the conditional it added is no longer reachable due to check-in [1409758f72c0206c]. (check-in: b3f26967 user: drh tags: trunk)
18:44
Move variable declaration to start-of-block for MSVC. (check-in: 55c136ef user: mistachkin tags: trunk)

17:06
Ensure the SF_Aggregate flag on a SELECT statement is set if a DISTINCT is transformed to a GROUP BY. Ticket [9c944882]. (check-in: 1409758f user: dan tags: trunk)

Fix DBSTAT so that it returns no rows, rather than an error when the WHERE clause is "schema=NULL". (check-in: 5b246b47 user: drh tags: trunk)
19:12
Fix harmless compiler warnings. (check-in: 8452fe03 user: drh tags: trunk)
18:38

Record when the OP_IfNotOpen branch is and is not taken. (check-in: 182a898b user: drh tags: trunk)
17:55
Remove another NEVER added by check-in [7b62555e285f32d3]. Dbsqlfuzz found another test case. (check-in: 481f4956 user: drh tags: trunk)
17:42
New test cases in test/in4.test require rtree, so disable those tests on builds that lack the rtree extension. (check-in: b5900914 user: drh tags: trunk)
16:55
Fix a problem where the loop for the RHS of a LEFT JOIN uses values from an IN() clause as the second or subsequent field of an index. (check-in: 95ef6896 user: dan tags: trunk)
15:37
Merge the latest fixes from trunk. (check-in: 26ef709a user: drh tags: new-security-options)
15:21
Fix a false-positive in the register validity tracking logic by moving the temporary register release call before the jump that uses that temporary register. (check-in: 9da48a5c user: drh tags: trunk)
14:57
Improve a testcase in test/fuzzdata8.db to make it more resilient. (check-in: 139aefe6 user: drh tags: trunk)
14:50
Back out another NEVER added by check-in [7b62555e285f32d3] - the test case was already in test/fuzzdata3.db, but it only occurs if compiled without SQLITE_ENABLE_PREUPDATE_HOOK. (check-in: 61f873b1 user: drh tags: trunk)
14:00
Omit the omit flag from eq constraints on column "aggregate" of dbstat virtual tables. Fix for [727074e2]. (check-in: 74ef6f2b user: dan tags: trunk)
12:34
Restore a NEVER and an assert in btree that was removed by check-in [7b62555e285f32d3]. Dbsqlfuzz found test cases. (check-in: 04a05c83 user: drh tags: trunk)
01:43
Enhance PRAGMA function_list so that it shows all instances of each FuncDef, the number of arguments, the encoding, the type, and the flags. Use this capability to locate and fix incorrect function flags in the standard build. (check-in: 9ca906d2 user: drh tags: new-security-options)
2020-01-03
21:57
Invert the SQLITE_FUNC_SAFE bit to be SQLITE_FUNC_UNSAFE. The external bit is still SQLITE_INNOCUOUS. It gets inverted as the appdef function is registered. (check-in: 1c266cb3 user: drh tags: new-security-options)
20:57
When UNSAFE_IN_VIEW is disabled, only allow functions in views that are tagged with SQLITE_INNOCUOUS. (check-in: 9ee79b25 user: drh tags: new-security-options)
20:16
In fts3, avoid making a very large memory allocation if the merge-hint record is corrupt. (check-in: 9add58fe user: dan tags: trunk)
17:40
Add NEVER macros to error-detection branches that were made unreachable (as far as I can tell) by check-in [ceacc28b03580334]. (check-in: 7b62555e user: drh tags: trunk)
16:38
Improvement to check-in [7405e98225761180] so that missing or null filenames given to the zipfile extension throw an immediate error. (check-in: 523e09bd user: drh tags: trunk)
15:51
Improve a specific case of early database corruption dectecion in the b-tree layer. (check-in: ceacc28b user: dan tags: trunk)
15:22
Merge fixes from trunk. (check-in: 002406df user: drh tags: new-security-options)
14:34
Remove an over-zealous ALWAYS() macro and add a test case that shows that the conditional can sometimes be false. (check-in: 536e9a9d user: drh tags: trunk)
14:27
Fix a possible NULL pointer dereference caused by using a "VALUES(...)" as a component of a compound SELECT with non-integer ORDER BY clause terms. (check-in: 9d791116 user: dan tags: trunk)
14:16
Fix the OP_Copy-coalesce optimization so that if the previous row happens to end with OP_Copy but is not a candidate for the optimization due to jumps, then the optimization is correctly bypassed. (check-in: b36126c1 user: drh tags: trunk)
13:55
Ensure that when a Select object is reset a new, empty, SrcList is allocated. (check-in: 4889cbf8 user: dan tags: trunk)
02:20
When generating the name of a view (or common table expression) because the SQL does not specify a name, avoid the names "true" and "false" which might be confused for the boolean literals of the same name, leading to an inconsistent abstract syntax tree. (check-in: ff9492d3 user: drh tags: trunk)
00:28
Fix a problem in sqlite3TreeViewBareExprList() in which the routine was not interpreting the new ExprList format correctly. (check-in: cd56872a user: drh tags: trunk)
2020-01-02
23:50
Merge enhancements from trunk. (check-in: 091403a6 user: drh tags: new-security-options)
22:28
Add the two-size lookaside memory allocator. Also, reduce the per-entry size of the ExprList object. (check-in: 51665bf0 user: drh tags: trunk)
22:23
NEVER() and ALWAYS() macros tagging unreachable branches. (Closed-Leaf check-in: 34b87774 user: drh tags: two-size-lookaside)
21:41
Merge the latest enhancements from trunk. (check-in: bd57e6d9 user: drh tags: two-size-lookaside)
21:30
Do not allow the zipfile virtual table to start a transaction if no filename has been specified. (check-in: 7405e982 user: drh tags: trunk)
19:50
Fix some test logic in the OP_Delete opcode so that it works after a cursor-trip. (check-in: 28900e5c user: drh tags: trunk)
18:37
Ifdef-out code that is only possible with the sessions extension. (check-in: 4fcf07f7 user: drh tags: trunk)
17:46
Have the OP_ReleaseReg opcode also invalidate the registers if P5 is non-zero. (check-in: 937be221 user: drh tags: trunk)
16:24
Handle blobs that are the return values of functions being cast to text in utf16 databases in the same way as blobs read directly from the database. Fix for [771fe617]. (check-in: e782096a user: dan tags: trunk)
15:02
Fix the OP_Move opcode so that it correctly manages dependency tracking. This change impacts debugging builds only. (check-in: 5377add4 user: drh tags: trunk)
14:42
Enhancements to aid testing and debugging: In PRAGMA vdbe_trace=on output, show pScopyFrom dependencies on register values. Add the sqlite3VdbeRegisterDump() procedure, callable from a debugger, that shows the values of all registers. Pass the VDBE pointer into test_trace_breakpoint() so that sqlite3VdbeRegisterDump() is callable from the breakpoint. (check-in: 9886cb4b user: drh tags: trunk)
13:26
Add the test_trace_breakpoint() subroutine that is invoked after each instruction is printed while running PRAGMA vdbe_trace=on. Only works for SQLITE_DEBUG builds. Also add parameters "pc" and "pOp" to test_addop_breakpoint() to make it easier to set conditionals. (check-in: 49a6368c user: drh tags: trunk)
02:50
Use OP_Copy instead of OP_SCopy to move the results of a scalar subquery. (check-in: 435c272d user: drh tags: trunk)
00:45
The sqlite3WhereEnd() call now unwinds all Expr modifications made by the sqlite3WhereBegin(). (check-in: 7bfd42f1 user: drh tags: trunk)
2020-01-01
23:02
Provide the -DSQLITE_ENABLE_INTERNAL_FUNCTIONS=1 compile-time option. Fix the ".testctrl internal_function" command in the CLI so that it does not signal an error on a valid input. (check-in: 8ee2ce92 user: drh tags: trunk)
21:14
When generating code for a subquery, make a copy of the Select object and generate the code out of the copy, in case the code generator makes modifications to expression and the Select object needs to be reused. (check-in: 4edddcc0 user: drh tags: trunk)
20:17
Ensure that when code for a scalar SELECT featuring window functions is generated more than once by the planner, separate ephemeral tables are opened for each instance. (check-in: ce141732 user: dan tags: trunk)
16:43
Fix the sqlite3ExprImpliesNonNullRow() routine so that it correctly handles a numeric comparison of two AND subexpressions. (check-in: 07e504d5 user: drh tags: trunk)
15:43
New test-only SQL functions: implies_nonnull_row(), expr_compare(), and expr_implies_expr(). The SQLITE_TESTCTRL_INTERNAL_FUNCTIONS test-control is modified to toggle internal function access on and off for a single database connection. (check-in: 473892a8 user: drh tags: trunk)
13:55
Factor out code generation for in-line SQL functions into a separate routine inside of expr.c. (check-in: 586a65a2 user: drh tags: trunk)
01:26
Issue OP_ReleaseReg opcodes against the array of registers used to compute index records after the index record has been computed. (check-in: e3330861 user: drh tags: trunk)
2019-12-31
23:17
Remove an incorrect assert() statement. Ticket [46fcd700b855e6d1] (check-in: eca7ec9c user: drh tags: trunk)
22:52
Experimental branch with new sqlite3_db_config() options that could possible enhance security for applications reading potentially compromised database files. (check-in: 96a2db26 user: drh tags: new-security-options)
18:39
Also set the SQLITE_DIRECTONLY flag on the load_extension() function. (check-in: 3bd095a5 user: drh tags: trunk)
18:12
Set the SQLITE_DIRECTONLY flag on the fts3_tokenizer() function of FTS3, thus preventing that function from being called from within a trigger or view. (check-in: f3171dc2 user: drh tags: trunk)
15:12
Refactor names. Use "small" instead of "mini" to describe the smaller of the two lookaside memory allocation sizes. (check-in: 88d24498 user: drh tags: two-size-lookaside)
14:49
Merge recent enhancements from trunk. (check-in: 39d55579 user: drh tags: two-size-lookaside)
12:18
The OP_ResultRow opcode releases the SCopy dependences on all its registers, as the values in those registers will not be reused. (check-in: 1dc83c5d user: drh tags: trunk)
2019-12-30
23:50
Back out the NEVER() from check-in [40d10e7aad5b8992] because it is reachable after all. Ticket [892575cdba4e1e36] (check-in: f481636f user: drh tags: trunk)
23:41
Add an ALWAYS() to a conditional which is apparently always true. (check-in: ea44c607 user: drh tags: trunk)
20:42
Put a NEVER() on a defensive branch. (check-in: 40d10e7a user: drh tags: trunk)
20:42
Fix a typo in a comment. No changes to code. (check-in: d4813a8d user: drh tags: trunk)
14:32
Do not use HIDDEN columns for NATURAL joins. Fix for [7c0e06b16]. (check-in: ab09ef42 user: dan tags: trunk)
06:55
In ALTER TABLE, rename columns and tables in expressions that are optimized out by the "AND 0" optimization. Doing this also fixes an otherwise harmless assert() failure. (check-in: a9e0354c user: dan tags: trunk)
2019-12-29
22:08
Do not allow triggers that run as part of REPLACE conflict resolution during an UPDATE to modify the the table being updated. Otherwise, those triggers might delete content out from under the update operation, leading to all kinds of problems. Ticket [314cc133e5ada126] (check-in: db4b7e1d user: drh tags: trunk)
00:52
Add the OP_FinishSeek opcode which completes an OP_DeferredSeek if the seek has not already completed. Also add the sqlite3WhereUsesDeferredSeek() interface to the query planner. The UPDATE implementation adds an OP_FinishSeek before running the final OP_Insert if one is needed. Ticket [ec8abb025e78f40c] and also an assertion fault reported by Yongheng. (check-in: 21ef6e99 user: drh tags: trunk)
2019-12-28
18:25
Do not attempt to flatten compound sub-queries in a FROM clause into the parent if any component of the sub-query uses a window function. (check-in: eeb76f62 user: dan tags: trunk)
18:08
Change an assert() in where.c to a testcase() macro, since the condition may be false. This was a problem with the assert() only, there is no bug in release builds that omit assert(). (check-in: 82be135d user: dan tags: trunk)
16:20
Disable early coding of transitive constraints at the end of each loop in the WHERE clause processing if the loop being coded is for a LEFT JOIN, even if the loop is part of an OR-clause optimization for virtual tables. Test cases in TH3. (check-in: 9421b442 user: drh tags: trunk)
15:24
Fix an instance where the planner might choose to use the OR-optimization when it adds no benefit. The same quirk causes an assert() to fail. This is not a bug in released versions - without the assert() the library still gets the right answer, it just does so less efficiently than it should. (check-in: f4bed1d7 user: dan tags: trunk)
14:33
Further improvements to .wheretrace during loop code generation. (check-in: c4d5b75c user: drh tags: trunk)
14:07
New enhancements to .wheretrace. The 0x20000 flag shows the WHERE clause before and after coding each loop. The 0x800 flag shows status at the start and at the end of each loop. An extra "C" tag is shown on coded terms. (check-in: 59cc46e5 user: drh tags: trunk)
13:39
Expose some of the Where data structure debug printing routines to the entire WHERE-clause processing module. (check-in: 85e76887 user: drh tags: trunk)
13:17
Add the --enable-all option to the main configure script as a short-hand to enable FTS4, FTS5, Geopoly/Rtree, JSON, and Sessions. In the amalgamation-autoconf, the --enable-rtree option (which is enabled by default) also now activates Geopoly. (check-in: 52ea0672 user: drh tags: trunk)
13:01
Simplifications to the initialization of the sqlite3_index_info structure that is used to communicate with virtual table modules. Avoid adding unused constraints to the sqlite3_index_info structure. Extra constraints are harmless, but might be confusing to people trying to understand the code. (check-in: 5e6357fc user: drh tags: trunk)
12:33
If the ".wheretrace 0x10000" bit is set, print WhereTerm.prereqAll and .prereqRight fields in the WhereTerm trace output. (check-in: a4f330b1 user: drh tags: trunk)
11:55
Two new test cases added to test/fuzzdata8.db. (check-in: 1be2c18f user: drh tags: trunk)
09:08
Second attempt to fix a problem with unwinding the WITH stack of the Parse object following an error. (check-in: 315d1f1a user: dan tags: trunk)
08:33
Merge latest trunk changes with this branch. (Closed-Leaf check-in: d693be37 user: dan tags: better-error-handling-1)
08:26
Fix an assert() failure in altertable3-22.4. (check-in: c566a91d user: dan tags: better-error-handling-1)
03:55
Fix a faulty assert() associated with query search limiting query plans. (check-in: 0d743585 user: drh tags: trunk)
02:40
Convert an assert() back into a conditional. The conditional was converted into an assert() by check-in [6ae4ad6ebee4db88] (2009-05-28) because we were unable to find a test case for it. Yongheng's fuzzer just now found that test case. (check-in: 4d0b9109 user: drh tags: trunk)

13:30
Follow-up to check-in [c8c6dd0e6582ec91] - change the xAccess() method to return true if the file exists and it is anything other than a regular file, or if it is a regular file with a non-zero file size. (check-in: 8a39803e user: drh tags: trunk)
08:57
When determining if an aggregate within a sub-query should be processed as part of the sub-query or an outer query, consider any FILTER clause in the same way as the arguments to the aggregate. (check-in: 1ffc045d user: dan tags: trunk)

If an UPSERT can cause an Abort due to a constraint failure, make sure the query planner knows this. Ticket [7c13db5c3bf74001]. (check-in: f14ce948 user: drh tags: trunk)
23:16
An UPDATE of a table that is indexed by a constant virtual column that uses the one-pass optimization might cause the table seek to be omitted before reaching row DELETE/INSERT. Fix this by coding an extra OP_Column in that circumstance. Ticket [ec8abb025e78f40c] (check-in: e5456049 user: drh tags: trunk)

When the sqlite3WindowRewrite() routine detects and error, have it convert the SELECT statement into just "SELECT null" so that it does not leave the parse tree in a goofy state that can cause problems with subsequent code before the stack has a chance to unwind and report the error. Ticket [d87336c81c7d0873] (check-in: fa58aad4 user: drh tags: trunk)

20:41
Thoroughly reset the rtree cursor at the start of each VFilter operation, including clearing its cache. This prevents left over pages in the cache which can cause problems on shutdown after a LEFT JOIN. Ticket [5eadca17c4dde90c] (check-in: 4c50afaf user: drh tags: trunk)
20:07
Remove an extra deflateInit2() call accidently left in check-in [f5ee30426e8876e7] (check-in: 953e6aa6 user: drh tags: trunk)

Fix a case in which SQLite could fail to identify "x BETWEEN ? AND ?" being true as implying that x is not null. Ticket [dfd66334]. (check-in: 2f179749 user: dan tags: trunk)
14:20
For expressions like (x, y) IN (SELECT ...) where the SELECT uses window-functions, require that all columns on the LHS be indexed before an index can be used. Fix for [d9ed4ebe]. (check-in: 0b1dbd60 user: dan tags: trunk)
13:24
Fix a shift-overflow problem in yesterday's check-in [36fdeb4f0a66970a] that OSSFuzz helpfully discovered overnight. Thanks Google. (check-in: bff38e2b user: drh tags: trunk)
03:37
Fix the OP_Cast operator so that when casting to TEXT, it always leaves the result in the encoding of the database. Ticket [0911b5d161b039c6]. Test cases in TH3. (check-in: f347744e user: drh tags: trunk)
02:43
Change the assert() back into a testcase(). See also check-ins [9ab985a9c8160b90] and [ddb17d92df194337] and other check-ins that those reference. Fix for ticket [9d708e474201c001] (check-in: 2c44c734 user: drh tags: trunk)
02:18
Enhance the sqlite3VdbeMemAboutToChange() shallow-copy validation mechanism by adding the new OP_ReleaseReg opcode to tell MemAboutToChange() that a range of registers is no longer needed so that the source register can be freely changed. This is a change to debugging and test builds only and does not impact release builds. Fix for ticket [c62c5e58524b204d] and [5ad2aa6921faa1ee]. The previous fix to ticket [5ad2aa6921faa1ee] is backed out by this change since this change is a better fix. (check-in: 36fdeb4f user: drh tags: trunk)
2019-12-22
23:48
Change the code generator for the IN operator so that it avoids creating OP_Eq and OP_Ne opcode with the same P1 and P3 arguments. This enables us to back out check-in [ddb17d92df194337] and also fix ticket [188f912b51cd802]. (check-in: 9ab985a9 user: drh tags: trunk)
20:29
Make a hard copy of strings in constraint checks prior to applying OP_RealAffinity, to avoid problems with a pointer accounting assert. This change is not strictly necessary - the correct answer is obtained without it and no UB occurs - however the pointer accounting asserts are useful to prevent other problems so it is a simple matter to bring this piece into compliance. Ticket [5ad2aa6921faa1ee] (check-in: 89a9dad6 user: drh tags: trunk)
20:03
When constructing the virtual MATCH term of the WHERE clause for a virtual table that is in a LEFT JOIN, be sure to set the correct Expr.iRightJoinTable value. This value does not appear to ever be used, except inside of a single assert(). But it is good to set it correctly, nevertheless. This fixes ticket [7929c1efb2d67e98], which as far as I can tell is completely harmless. (check-in: ef604882 user: drh tags: trunk)
19:41
In the WHERE clause debugging output (the .wheretrace output) show the parent index of any WhereTerm that is a child. (check-in: 7fc73332 user: drh tags: trunk)
18:55
Fix to the optimization of check-in [a47efb7c8520a011] that reads the values of expressions used in an index-on-expression directly from the index rather than recomputing the value. If the expression has a top-level COLLATE or unlikely() operator, be sure to clear the corresponding flags prior to converting it into a TK_COLUMN expression. Failure to do this is most likely harmless in production, but might cause an assertion fault in debugging builds. Ticket [b0cb8aff561a6dcd]. Test cases in TH3. (check-in: 56539e1c user: drh tags: trunk)
18:23
Back out the asserts of check-ins [a500893b6f64aced] and [d9c9fe9f5ad3fc91] as ticket [1b06916e01c82b66] demonstrates a case that refutes them. (check-in: ddb17d92 user: drh tags: trunk)
18:06
When parsing a CREATE TABLE from the sqlite_master table, delete the CHECK constraints if there are any errors, since there might otherwise be attempts to use those CHECK constraints if PRAGMA writable_schema=ON is set. This undoes the fix in check-in [ea721b34477ab8b4] for a more general solution. (check-in: a982e643 user: drh tags: trunk)
17:32
Ensure sqlite3WindowRewrite() is called on a SELECT statement before any terms aremoved from it as part of IN() clause processing. Fix for [f00d096ca]. (check-in: 8c856404 user: dan tags: trunk)
14:29
Fix "PRAGMA data_version" so that it works the same way with locking_mode=PERSIST and journal_mode=PERSIST configured. Fix for 7a458c2a5f. (check-in: 45748e2d user: dan tags: trunk)

Fix a spurious report of corruption from the fts3/4 integrity-check triggered by using the languageid option. (check-in: 70815e27 user: dan tags: trunk)
19:37
When creating a new virtual table, ensure that the OP_ParseSchema opcode processes the correct entry in the sqlite_master table even if there is a second entry with the same name and table values due to database corruption and the use of writable_schema=ON. Dbsqlfuzz find. (check-in: 4dbb6e1c user: drh tags: trunk)
14:09
When a corrupt schema is loaded using writable_schema=ON, the CHECK constraints (or other expressions in the table definition) might not be fully resolved.

Fix harmless compiler warnings. (check-in: 2bbd014c user: drh tags: trunk)
13:24
Ensure fts5 consistently calls sqlite3_value_text() before sqlite3_value_bytes(). This matters when storing blobs in fts5 tables within utf-16 databases. Fix for [cf36cb4e02]. (check-in: c16305eb user: dan tags: trunk)

Fix the regexp extension so that it correctly translates all over-length 3-byte UTF8 sequences into 0xfffd. (check-in: 3d4c0bf8 user: drh tags: trunk)
20:37
When an error occurs while rewriting the parser tree for window functions in the sqlite3WindowRewrite() routine, make sure that pParse->nErr is set, and make sure that this shuts down any subsequent code generation that might depend on the transformations that were implemented. This fixes a problem discovered by the Yongheng and Rui fuzzer. (check-in: e2bddcd4 user: drh tags: trunk)
17:42
Detect the invalid use of NULLS LAST on an INTEGER PRIMARY KEY definition of a WITHOUT ROWID table. (check-in: 4417c5bf user: drh tags: trunk)

21:22
Change an unreachable testcase() into an assert() (check-in: 062e00c4 user: drh tags: trunk)
20:51
Continue to back away from the LEFT JOIN optimization of check-in [41c27bc0ff1d3135] by disallowing query flattening if the outer query is DISTINCT. Without this fix, if an index scan is run on the table within the view on the right-hand side of the LEFT JOIN, stale result registers might be accessed yielding incorrect results, and/or an OP_IfNullRow opcode might be invoked on the un-opened table, resulting in a NULL-pointer dereference. This problem was found by the Yongheng and Rui fuzzer. (check-in: 86297431 user: drh tags: trunk)
13:42
Add the --vdbe-debug option to fuzzcheck. (check-in: 289158aa user: drh tags: trunk)

Correctly unwind the savepoint stack if the database goes read-only in the middle of a savepoint. (check-in: a96d02b4 user: drh tags: trunk)
01:31
Remove an assert() in the code generator that can fail due to an invalid INSERT statement. The same assert() appears again in the VDBE and will fire there if the problem persists in an SQL statement that does not contain errors. Gramfuzz find. (check-in: 9bdd57cb user: drh tags: trunk)
00:05
When processing constant integer values in ORDER BY clauses of window definitions (see check-in [7e4809eadfe99ebf]) be sure to fully disable the constant value to avoid an invalid pointer dereference if the expression is ever duplicated. This fixes a crash report from Yongheng and Rui. (check-in: 1ca0bd98 user: drh tags: trunk)
2019-12-17

16:52
When a table is part of a LEFT JOIN and should be a completely NULL row due to the semantics of a LEFT JOIN, make sure any generated columns on that row evaluate to NULL. Ticket [3b84b42943644d6f] (check-in: 02714914 user: drh tags: trunk)
2019-12-15
02:49
Ensure that all ON CONFLICT REPLACE indexes are sorted to the end of the list of indexes for a table, even for weird cases where the same UNIQUE constraint occurs twice with the ON CONFLICT REPLACE clause only on the second one. This avoids an out-of-order contraint processing problem that can arise due to the optimization of check-in [469a62ca33081854]. (check-in: 1e3918ca user: drh tags: trunk)
00:36
Abort the OP_Savepoint opcode early if a virtual table xSync method fails, perhaps due to an interrupt. (check-in: 672e749a user: drh tags: trunk)
2019-12-14
19:55
When a generated column expression is initially parsed, if it contains errors convert the expression to a simple NULL. This prevents additional pieces of the expression tree that are allocated from lookaside from leaking into the schema, where lookaside allocations are not allowed. (check-in: a89b3860 user: drh tags: trunk)
18:08
Due to the previous change, the p5 parameter to OP_VColumn no longer ever contains extraneous bits, so change a testcase() into an assert() to show as much. (check-in: 5b4a88cd user: drh tags: trunk)
17:43
Do not set OP_Column flags on the instructions generated by sqlite3ExprCodeGetColumn() if the opcode generated is not really an OP_Column, which might happen if the column is virtual. Fix for ticket [b439bfcfb7deedc6] (check-in: 2401e047 user: drh tags: trunk)
15:01

Patch to the page cache to avoid harmless pointer arithmetic that due to bugs in the STD-C spec is technically UB. This is to fix a harmless UBSAN complaint that OSSFuzz is hitting. (check-in: c29fc212 user: drh tags: trunk)
16:04
Change the default lookaside configuration to 40 slots of 1200-bytes each. This actually works out to 30 big slots and 93 small slots using the mini-lookaside allocator. We get the same (or better) lookaside coverage but with 72KB less memory per connection. (check-in: 47b71a84 user: drh tags: two-size-lookaside)

Tie up the loose ends in the ExprList size reduction. (Leaf check-in: 59d0f3af user: drh tags: two-size-lookaside, exprlist-size-reduction)
2019-12-12
22:11
Work toward reducing the incremental size of an ExprList object to 24-byte per entry, from 32-bytes (on a 64-bit machine). This helps the new mini-lookaside allocator to run better by avoiding excessive reallocs. The current change mostly works, but still has a few loose ends to tie up. This check-in is merely a snapshot to save my work. (check-in: fdda76cf user: drh tags: two-size-lookaside, exprlist-size-reduction)

Fix an issue where malloc could be used to fulfill a small allocation when a large lookaside slot could have beeen used instead. (check-in: 611020e3 user: numist tags: two-size-lookaside)
20:22
Change the name of the Expr.a.zName field to zEName, so that it has a name that is distinct from other fields and variables and is hence easier to grep for. (check-in: d3783357 user: drh tags: two-size-lookaside)
17:17
Change the size of a mini-lookaside allocation to a macro (MINI_SZ) rather than a magic number (128). (check-in: 5e1949bc user: drh tags: two-size-lookaside)

Merge enhancements from trunk. (check-in: 6cb053f9 user: drh tags: two-size-lookaside)
15:19
Factor out the conditional (which is only true for rare errors) from the notValid() function in resolve.c, for a performance improvement and size reduction. Also cause failures to set the Expr node to a NULL operator so that it does not cause problems later in case PRAGMA writable_schema=ON has been set. Test cases in TH3. (check-in: c6af9f65 user: drh tags: trunk)

Improved tracing output from the LEMON-generated parser. (check-in: 4d6d2fc0 user: drh tags: trunk)
16:22
Strengthen check-in [83da4d4104ee1870] by ignoring *all* WHERE-clause constraints for a virtual table that is the right table of a LEFT JOIN, as such constraints are never useful. This fixes an issue discovered by Manuel Rigger. (check-in: 840de36d user: drh tags: trunk)
15:07
When trying to drop a virtual table that has no xDestroy method, invoke the xDisconnect method rather than doing nothing, to avoid a memory leak. (check-in: 1fa29a5f user: drh tags: trunk)

Fix the NOT NULL verification logic in PRAGMA integrity_check so that it works for generated columns whose value is the result of a comparison operator. Ticket [bd8c280671ba44a7] (check-in: f3b39c71 user: drh tags: trunk)
14:34
Fix a gramfuzz find. If a partial index that does not reference any column of its table is used by an UPDATE statement in one-pass mode, then avoid the use of OP_DeferredSeek since the seek might not be resolved prior to the OP_Delete and OP_Insert that implement the UPDATE. (check-in: e3398c5f user: drh tags: trunk)

In the rtree extension, actively suppress extra tokens on the column names, and be pedantic about column affinities. Ticket [367a86e28859f1ff] (check-in: 97fb5a72 user: drh tags: trunk)
11:48
The check-in [b7810062ec2489e1] was not quite right in that it allowed an oversized shift operation (which is UB in C) on some obscure inputs. OSSFuzz found the problem for us overnight. (check-in: 62f2235a user: drh tags: trunk)
01:38
Further enhancements to RTREE, following up to check-in [f898d04cf272ef01] so that constraints are allowed to be compared to strings that look like numbers. Ticket [aa573a787b8f1fdf] (check-in: 32772dfd user: drh tags: trunk)

21:46
Fix to the rowvalue logic that avoids disabling rowvalue inequality contraints on a virtual table when the virtual table sets the omit flag. The logic has been incorrect since row-values were added. However, this does not come up often as very few virtual tables implement inequality constraints using the omit flag. Ticket [f096d191b6641daa] (check-in: b7810062 user: drh tags: trunk)
18:29
Documentation update: Clarify that the sqlite3_index_info.aConstraintUsage.omit flag is a hint only and that the code generator is not obligated to follow the hint. (check-in: 7d3e3f6e user: drh tags: trunk)

Revise the SQLITE_OPEN_NOFOLLOW so that it actually uses O_NOFOLLOW in the open() system call. This backs out the SQLITE_ACCESS_SYMLINK value but adds the new SQLITE_OK_SYMLINK return code from the xFullPathname method of sqlite3_vfs when that routine resolves symbolic links.

15:08
Remove the "fastfuzztest" makefile target. Use only "fuzztest". (check-in: e17571c7 user: drh tags: trunk)

2019-10-05
19:53
Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis.

The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] (check-in: dd661348 user: drh tags: trunk)
15:11
The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] (check-in: 057fb8b1 user: drh tags: trunk)
13:07
The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] (check-in: 45ff2b1f user: drh tags: trunk)

Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. (check-in: 616f5663 user: dan tags: trunk)
15:06
Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. (check-in: 84ae41fd user: dan tags: trunk)
14:25
Fix a potential buffer overrun in fts5 caused by corrupted database records. (check-in: c465d0eb user: dan tags: trunk)

Improve Lemon so that it enlarges some of its tables slightly in order to avoid having to index range checks on table lookups for a performance increase. (check-in: 4be6a23a user: drh tags: trunk)
2019-08-28
11:49
Fix an unreachable branch in sqlite3ParserFallback() (Closed-Leaf check-in: e059178b user: drh tags: lemon-optimization)

Further improvements to parser speed by enlarging lookup tables to eliminate the need to do range checking on the index prior to lookup. (check-in: 47d3e091 user: drh tags: lemon-optimization)
02:09
Increase the size of the yy_lookahead table so that it is never necessary to down bounds checking on the index. (check-in: bafd8723 user: drh tags: lemon-optimization)
2019-08-27
19:59
Add support for "ORDER BY ... NULLS FIRST" and "ORDER BY ... NULLS LAST". Use this to fix ticket [f8a7060e]. (check-in: 94085fb3 user: dan tags: trunk)

The ALWAYS() added by the previous check-in was incorrect. Take it back out. (check-in: 336235db user: drh tags: trunk)
17:28
Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. (check-in: aff20980 user: drh tags: trunk)
17:01
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)

If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] (check-in: 069c2f4c user: drh tags: trunk)

Fix the built-in edit() SQL function in the CLI so that it works with zero-length blobs. (check-in: e3249012 user: drh tags: trunk)
21:11
Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. (Closed-Leaf check-in: 12d2cf88 user: drh tags: dead-end)
20:33
Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. (check-in: d26fdfa3 user: dan tags: nulls-last)

Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f49 user: drh tags: nulls-last)
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)

16:36
Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. (check-in: 07babb0f user: dan tags: nulls-last)
16:25
For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. (check-in: 636ca447 user: drh tags: trunk)

Fix harmless compiler warnings. (check-in: 1eef4dde user: drh tags: trunk)
19:19
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)

2019-08-06
21:16
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)

Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. (check-in: 846d2d2d user: drh tags: trunk)
18:40
Add "PRAGMA foreign_keys=OFF;" to the start of the script output by ".recover", just as is done for ".dump". (check-in: bfc29e62 user: dan tags: trunk)
15:32
Ensure that columns of views and sub-queries that are expressions with no affinity are comparied without any type conversions, as required in the documentation. Tickets [61c853857f40da49] and [d52a29a9e6bc55c5]. (check-in: 9c8c1092 user: drh tags: trunk)

15:02
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)
11:45
Add an assert() to the code on this branch. (check-in: fdd44bbb user: dan tags: reuse-schema)
2019-08-05
20:53
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)

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)

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)

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. 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].

Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. (check-in: d612fb78 user: drh tags: trunk)

17:10
Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes). This avoids corner cases of comparing integers against real values that are beyond the resolution of an IEEE 754 double. Fix for ticket [6c1d3febc00b22d457c78c2] (check-in: 9b091527 user: drh tags: trunk)

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.

Test case changes so that they work with both Tcl8.6 and Tcl8.7. (check-in: 7b771405 user: drh tags: trunk)
13:40
Tweaks to wapptest.tcl: Ensure that the "Debug" checkbox is disabled unless the app is in "config" state, and have Debug variants run "test" instead of "fulltest". (check-in: dd248c18 user: dan tags: trunk)
12:10
Fix minor problems in tcl test scripts. (check-in: 56b66418 user: dan tags: trunk)

17:06
Remove the vfslog.c extension from the testfixture target in main.mk, as that extension has no TCL bindings and is inaccessible. (check-in: d71f8bbc user: drh tags: trunk)
16:54
Fix RBU so that it does not write rows that should be excluded into partial indexes (corrupting the database). (check-in: 31eb27f4 user: dan tags: trunk)
06:50
Fix the checksymbols target in Makefile.in. (check-in: 1956eb34 user: dan tags: wapptest)
2019-04-10

Update the list of OMIT options in the omittest.tcl script. (check-in: f294cfc1 user: drh tags: trunk)
13:24
Further refinement of the sqlite3VdbeMEmExpandBlob() fix of check-in [df58774e994bd] to prevent a reference to an unused variable - problem discovered by Valgrind. (check-in: 09435b57 user: drh tags: trunk)

21:17
Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0b 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: d2728192 user: drh tags: trunk)
20:47
Add further tests so that veryquick.test covers all vdbe branches. (check-in: cbc67de5 user: dan tags: trunk)

Add the ability to override the new corruption detection logic of the previous checkin, in order to exercise downstream corruption detection during testing. (check-in: e859d318 user: drh tags: trunk)
15:44
In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. (check-in: af1e5873 user: drh tags: trunk)
2019-04-04
22:05
Add the vtab enable/disable options to the sqlite3_db_config TCL command in the testfixture. (Leaf check-in: c7052428 user: drh tags: disable-vtab)

18:20
Minor fixes to requirements marks. (check-in: 02ebc60b user: drh tags: trunk)
17:58
Add test cases to improve coverage of VDBE branches. Still some to go. (check-in: 4cef609d user: dan tags: trunk)

Correctly initialize the loadable extension thunk. (check-in: 4fca46de user: drh tags: trunk)
15:25
Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. (check-in: 9cac5ac1 user: drh tags: trunk)
14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb4 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: 13a0ea64 user: drh tags: trunk)
2019-04-03
17:54
Add a defense-in-depth NEVER() test to the WAL cleanup code. (Leaf check-in: 1109942a user: drh tags: branch-3.27)

2019-04-02
18:12
Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. (check-in: bce01d95 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: bc0fb1c3 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: 10aedce3 user: drh tags: trunk)
13:10
Put the list of keywords in mkkeywordhash.c into alphabetical order. (check-in: ac98b23b user: drh tags: trunk)
01:00
Merge fixes from trunk. (check-in: 20372906 user: drh tags: apple-osx)
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)
00:48
Add new APIs to the extension loading mechanism. (check-in: 6f122faf user: drh tags: trunk)
00:34

17:24
If the library is built with SQLITE_VDBE_COVERAGE defined, have the Tcl tests generate a vdbe coverage report in file testdir/vdbe_coverage.txt. (check-in: f0ed7146 user: dan tags: trunk)
16:23
Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. (check-in: fa37cf9a user: drh tags: trunk)
15:55
Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. (check-in: a69bb4f2 user: drh tags: trunk)

19:17
Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. (check-in: bb643bac 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: fb125bd3 user: drh tags: trunk)
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56d user: drh tags: trunk)
17:07
Add an extra IO-error test to windowfault.test. (check-in: 5b8c44cd user: dan tags: trunk)
2019-03-29
17:26
Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. (check-in: 27160df7 user: drh tags: value_frombind)
15:21
Remove the unused P5 flag from the OP_Rewind opcode. (check-in: c2edbf3b user: drh tags: trunk)
13:17
Fix a fairly obscure problem causing the planner to sometimes choose sub-optimal plans for a query with a single virtual table in the FROM clause, and at least one IN(...) constraint in the WHERE clause. (check-in: f5752517 user: dan tags: trunk)
11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. (check-in: 040d5d51 user: drh tags: trunk)
11:39
The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. (check-in: ab76e3a9 user: drh tags: value_frombind)
11:13
Initial implementation of the sqlite3_value_frombind() interface. (check-in: 98da62df user: drh tags: value_frombind)

Show the pointer address for Window objects in the TreeView display. (check-in: 1ae70ad2 user: drh tags: trunk)
13:35
More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. (check-in: d6a07433 user: drh tags: trunk)
13:03
Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. (check-in: ec2f207d user: drh tags: trunk)
04:03
If the string formatter in sqlite3NestedParse() fails due to an over-length string, make sure this error is recorded by the parser so that it knows to fail. (check-in: 85e53ff1 user: drh tags: trunk)

Fix a problem with window frames that use "BETWEEN <start> AND 0 PRECEDING". (check-in: 7927b6b0 user: dan tags: trunk)
16:21
Fix harmless compiler warnings. (check-in: a063f7c4 user: drh tags: trunk)
14:04
Use the mutex-free PRNG in this branch, since anybody using this branch is probably interested in high concurrency. (check-in: e88fc6d0 user: drh tags: begin-concurrent)
13:28
Bring this branch into closer alignment with begin-concurrent. (check-in: 6433d366 user: drh tags: begin-concurrent-pnu)

22:05
Fix an obsolete comment in the CLI. No code changes. (check-in: fade103c 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)
11:38
Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. (check-in: b99f8512 user: drh tags: trunk)

Remove assert() statements based on the counter-factual proposition that 0 is not a valid cursor number. (check-in: c7b33618 user: dan tags: window-functions)
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)
20:02
Use the IsReuseSchema() macro more consistently. Also, rename it to IsSharedSchema(). (check-in: c1be211c user: dan tags: reuse-schema)

11:16
Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. (check-in: 90acdbfc user: drh tags: trunk)
05:45
Fix various harmless compiler warnings seen with MSVC. (Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings)

Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af5 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: 0e64ac12 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: d3915230 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: 90c5a17c 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: c2d50df8 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: 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)

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)
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: be21a641 user: drh tags: trunk)

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)

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)
2019-02-14

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)

11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. (check-in: 4a4952d3 user: dan tags: trunk)
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. (check-in: 7b412224 user: drh tags: trunk)
2019-02-09
22:33
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)
2019-02-07

2019-02-06
20:49
Ensure all bytes of the PgHdr1 structure are initialized. This avoids a valgrind error when running corruptI.test. (check-in: a505e34d user: dan tags: trunk)
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. (check-in: 0e6249cb user: dan 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

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)

01:39
Improvements to "PRAGMA parser_trace=ON": Make it a flag pragma, and then use the flag to show the complete SQL text at the beginning of the parse. (check-in: 507c4353 user: drh tags: trunk)

Improvements to the ".eqp trace" command in the CLI so that it ensures that the schema has been read prior to activing the tracing feature, to avoid cluttering the output with a trace of the schema parse. (check-in: 42687d45 user: drh tags: trunk)
02:45
New test cases form dbsqlfuzz (check-in: 9cf8ebd1 user: drh tags: trunk)
