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

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: 56869f54f3 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: 4b73e151cd user: dan tags: rbu-replace-hack)
2021-07-13
15:30
Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. This allows the SQL associated with CVE-2020-13871 (ticket [c8d3b9f0a750a529]) to be tested. (Closed-Leaf check-in: 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)
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: 0c3838d951 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. (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)
2020-05-25
12:02
Make sure variable declarations are at start of scope even when SQLITE_ENABLE_SNAPSHOT is used. (check-in: a77ceaf6ba user: drh tags: trunk)
01:31
Attempt to work around a false-positive warning in the CGo compiler. (Closed-Leaf check-in: d4bf60f464 user: drh tags: cgo-warning-workaround)
2020-05-24
12:36
Version number to 3.32.1. (check-in: 56e5063c32 user: drh tags: trunk)
03:38
When rewriting a query for window functions, if the rewrite changes the depth of TK_AGG_FUNCTION nodes, be sure to adjust the Expr.op2 field appropriately. Fix for ticket [7a5279a25c57adf1] (check-in: ad7bb70af9 user: drh tags: trunk)
03:01
Move some utility Walker callbacks into the walker.c source file, as they seem to belong there better. (check-in: dac438236f user: drh tags: trunk)
02:05
Improvements to parse-tree tracing logic. No changes in deliverable code. (check-in: f7e5a68a7e user: drh tags: trunk)
00:30
Minor fix to a comment. No code changes. (check-in: efdbb2b499 user: drh tags: trunk)
2020-05-23
19:58
Limit the "precision" of floating-point to text conversions in the printf() function to 100,000,000. Fix for ticket [23439ea582241138]. (check-in: d08d340587 user: drh tags: trunk)
17:56

2020-05-20
15:02
Back out the change from [7fab1393c2b22b1f] that tries to convert invalid surrogate characters in UTF16 into the replacement character 0xfffd, as we find that this breaks some software. (check-in: 4218c7b71f user: drh tags: trunk)
2020-05-19
15:51

11:36
Fix SQLITE_OMIT_VIRTUALTABLE testfixture builds. (check-in: 3d9780c5f6 user: dan tags: trunk)

19:54
The only known path to a corruption detection branch was cut off by the previous commit implementing earlier index corruption. So make the branch NEVER. Maybe a fuzzer will find a new path. (check-in: 9a84d8eb44 user: drh tags: trunk)
18:42
Earlier detection of index corruption caused by missing index entries. (check-in: f339f31f9e user: drh tags: trunk)

Do not factor out constant functions into the initialization section of a prepared statement, because even though they are constant, they can still throw exceptions. Instead, put such functions in an OP_Once block. This fixes ticket [3c9eadd2a6ba0aa5] and causes COALESCE() and CASE...END to be short-circuit. (check-in: c5f96a085d user: drh tags: trunk)

Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc].

Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] (check-in: 3e3c60d812 user: drh tags: trunk)
22:25
Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner.

New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal(). Also sqlite3_uri_key(). And the other sqlite3_uri functions now work using the journal or wal filename in addition to the database file. And the sqlite3_db_filename() result is guaranteed to work as an argument to the sqlite3_uri functions. (check-in: fd7bcc5352 user: drh tags: trunk)

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: e1154c39ba user: drh tags: trunk)
19:30
Merge enhancements from trunk. (check-in: 9c50f6c28a user: drh tags: new-security-options)

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: 69f6a7e42f 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: b3f2696705 user: drh tags: trunk)

When UNSAFE_IN_VIEW is disabled, only allow functions in views that are tagged with SQLITE_INNOCUOUS. (check-in: 9ee79b254e 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: 9add58fe96 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: 7b62555e28 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: 523e09bd22 user: drh tags: trunk)
15:51
Improve a specific case of early database corruption dectecion in the b-tree layer. (check-in: ceacc28b03 user: dan tags: trunk)
15:22
Merge fixes from trunk. (check-in: 002406df22 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: 536e9a9d1b 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: 9d79111642 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: b36126c188 user: drh tags: trunk)
13:55
Ensure that when a Select object is reset a new, empty, SrcList is allocated. (check-in: 4889cbf898 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: ff9492d3ff 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: cd56872afb user: drh tags: trunk)

23:50
Merge enhancements from trunk. (check-in: 091403a670 user: drh tags: new-security-options)

Fix some test logic in the OP_Delete opcode so that it works after a cursor-trip. (check-in: 28900e5cab user: drh tags: trunk)
18:37
Ifdef-out code that is only possible with the sessions extension. (check-in: 4fcf07f796 user: drh tags: trunk)

Have the OP_ReleaseReg opcode also invalidate the registers if P5 is non-zero. (check-in: 937be22106 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: e782096aa0 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: 5377add4b8 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: 9886cb4b79 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: 49a6368c38 user: drh tags: trunk)
02:50
Use OP_Copy instead of OP_SCopy to move the results of a scalar subquery. (check-in: 435c272dcf user: drh tags: trunk)
00:45
The sqlite3WhereEnd() call now unwinds all Expr modifications made by the sqlite3WhereBegin(). (check-in: 7bfd42f1dc 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: 8ee2ce92c0 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: 4edddcc0bc 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: ce14173252 user: dan tags: trunk)
16:43
Fix the sqlite3ExprImpliesNonNullRow() routine so that it correctly handles a numeric comparison of two AND subexpressions. (check-in: 07e504d517 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: 473892a8ec 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: 586a65a28f user: drh tags: trunk)

Remove an incorrect assert() statement. Ticket [46fcd700b855e6d1] (check-in: eca7ec9cda 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: 96a2db2612 user: drh tags: new-security-options)
18:39
Also set the SQLITE_DIRECTONLY flag on the load_extension() function. (check-in: 3bd095a531 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: f3171dc22e 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: 88d2449838 user: drh tags: two-size-lookaside)
14:49
Merge recent enhancements from trunk. (check-in: 39d5557937 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: 1dc83c5d54 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: f481636f1a user: drh tags: trunk)
23:41
Add an ALWAYS() to a conditional which is apparently always true. (check-in: ea44c607b8 user: drh tags: trunk)
20:42
Put a NEVER() on a defensive branch. (check-in: 40d10e7aad user: drh tags: trunk)

Do not use HIDDEN columns for NATURAL joins. Fix for [7c0e06b16]. (check-in: ab09ef4271 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: a9e0354c99 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: db4b7e1dc3 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: 21ef6e9933 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: eeb76f621d 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: 82be135dee 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: 9421b442ca 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: f4bed1d7af user: dan tags: trunk)
14:33
Further improvements to .wheretrace during loop code generation. (check-in: c4d5b75c93 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: 59cc46e5a6 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: 85e7688776 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: 52ea0672d7 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: 5e6357fc95 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: a4f330b133 user: drh tags: trunk)
11:55
Two new test cases added to test/fuzzdata8.db. (check-in: 1be2c18f40 user: drh tags: trunk)

Fix an assert() failure in altertable3-22.4. (check-in: c566a91d5c user: dan tags: better-error-handling-1)
03:55
Fix a faulty assert() associated with query search limiting query plans. (check-in: 0d743585c2 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: 4d0b9109f7 user: drh tags: trunk)
01:52
When an INSERT is receiving content from a SELECT, run an OP_ReleaseReg opcode at the top of each iteration of the loop in order to prevent spurious OP_SCopy misuse complaints. Ticket [de4b04149b9fdeae] (check-in: 6afadd3b3a user: drh tags: trunk)
00:36
Recompute the values for all generated columns after NOT NULL ON CONFLICT REPLACE constraints fire. Tickets [37823501c68a09f9] and [5fbc159eeb092130]. (check-in: 4cc12c1886 user: drh tags: trunk)
2019-12-27
20:54
Do not attempt to unwind the WITH stack in the Parse object following an error. This fixes a separate case to [de6e6d68], but also causes an assertion fault at select.c:4666 for test case altertab3-22.4. (check-in: d29edef934 user: dan tags: better-error-handling-1)
20:06
Remove a NEVER() that is no longer true. Fix for [36ffedcb9]. (check-in: 597896ed0a user: dan tags: trunk)

Fix a problem involving window function aliases being referenced from sub-selects. (check-in: e3b5fc05c0 user: dan tags: trunk)
18:15
Add a missing "ifcapable rtree {...}" line to the window1.test test module. (check-in: 4e6fbb1a51 user: drh tags: trunk)

Fix a problem with window functions in aggregate queries that do not have GROUP BY clauses. (check-in: 99609786f4 user: dan tags: trunk)
15:31
Do not mistake constant integers in a PARTITION BY expression for references to ORDER BY style references to values returned by the SELECT statement. (check-in: 45c64d39d5 user: dan 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: 8a39803ef8 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: 1ffc045d2b user: dan tags: trunk)
01:50
Ensure that the Pager.changeCountDone flag is cleared whenever dropping the write lock, even when transitioning from EXCLUSIVE locking mode into NORMAL locking mode while in WAL mode. Ticket [fb3b3024ea238d5c]. (check-in: 846b1de6e5 user: drh tags: trunk)
00:19
Fix buffer underflows in the zipfile extension associated with zero-length or NULL filename in the ZIP archive. But report on the mailing list by Yongheng and Rui. (check-in: 465a15c5c2 user: drh tags: trunk)
2019-12-26
23:40
If an UPSERT can cause an Abort due to a constraint failure, make sure the query planner knows this. Ticket [7c13db5c3bf74001]. (check-in: f14ce94866 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: e545604959 user: drh tags: trunk)
14:36
Fix an assert() in fts5 that could fail if an xSavepoint() call on another vtab fails. Fix for [167b2aac] . (check-in: a5d7f5d24a user: dan tags: trunk)
01:10
Makefile.in fix so that it works on systems that require a .EXE suffix on executables. (check-in: f482a4cdfa user: drh tags: trunk)
01:02
Add two new fuzzer test cases from dbsqlfuzz. (check-in: f8d5586a8c user: drh tags: trunk)
00:56
In the xAccess() method of the unix VFS, return true if the named object is a directory, regardless of what stat() reports as the st_size for the object. Different filesystems report st_size differently for directories. Problem reported on the mailing list by Stefan Brüns. (check-in: c8c6dd0e65 user: drh tags: trunk)
00:54
Fix an FTS3 test case that depends on the ICU extension so that it only runs if SQLite is compiled with ICU. (check-in: 19c6240bdb user: drh tags: trunk)
00:53
Fix an incorrect assert() added by check-in [fa58aad48a788802]. Problem found by dbsqlfuzz. (check-in: a17b29f08c user: drh tags: trunk)
00:20
Disable the optimization that tries to pull the value of an expression from an index on that expression if the expression is a constant. (check-in: e5fd8b5050 user: drh tags: trunk)
2019-12-25
23:54
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: fa58aad48a user: drh tags: trunk)
2019-12-24
21:42
Fix a minor performance regression from check-in [401c9d30e06191d9] (check-in: 76f54ee867 user: drh tags: trunk)
21:01
Backout the early VTable cursor close change from yesterday, as Yongheng and Rui have found a test case for which it fails. The new test case is added to fuzzcheck. (check-in: ddb10f0374 user: drh tags: trunk)
20:51
Fix a problem causing fts5 integrity-check failures if numeric values are inserted into a table within a utf-16 database. Fix for [752fdbf6]. (check-in: bae060f382 user: dan tags: trunk)
18:53
Make the zipfile() extension function more robust against zero-length filenames. (check-in: b9c2005f02 user: drh tags: trunk)

Fix another case where malformed utf-8 was being mishandled in fts5. Fix for [df46a6f3]. (check-in: 1c0a05b09a user: dan tags: trunk)
15:35
Fix an assert() added as part of commit [a11b393dc] that can fail if fts5 database records are corrupt. (check-in: 4630c1ec01 user: dan tags: trunk)
15:01
Extra defense against problems following an OOM. dbsqlfuzz find. Also import the latest dbsqlfuzz test cases. (check-in: 0a70f5ddaf user: drh tags: trunk)
14:27
Fix a spurious report of corruption that could be made by the fts5 integrity-check in SQLITE_DEBUG builds if the fts5 index contains malformed utf text. Ticket [d62981b76de521e3] (check-in: a11b393dc2 user: dan tags: trunk)
13:41
Convert an ALWAYS() into an assert() with an extra error term. Dbsqlfuzz find, with test case in TH3. (check-in: b473ad35c5 user: drh tags: trunk)

Allow comparison operators of a register against itself. Ticket [188f912b51cd802a], (check-in: 401c9d30e0 user: drh tags: trunk)
2019-12-23
21:11
Test case for the zipfile-extension bug fix of the previous check-in. (check-in: bc8bfc7fcd user: drh tags: trunk)
21:04
Fix the zipfile() function in the zipfile extension so that it is able to deal with goofy filenames that contain embedded zeros. (check-in: cc0fb00a12 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: 4c50afafce user: drh tags: trunk)
20:07
Remove an extra deflateInit2() call accidently left in check-in [f5ee30426e8876e7] (check-in: 953e6aa6d9 user: drh tags: trunk)
19:28
Do an early close of virtual table cursors to avoid unnecessary cursor contention in UPDATE for some virtual table implementations. Ticket [56a74875be799b85] (check-in: eb95dac7f6 user: drh tags: trunk)
18:02
Early detection of database corruption in balance_deeper(). (check-in: 61c2233654 user: drh tags: trunk)
15:17
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: 2f17974912 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: 0b1dbd60f5 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: bff38e2b53 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: f347744e0d 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: 2c44c73499 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: 36fdeb4f0a 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: 9ab985a9c8 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: 89a9dad633 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: ef604882a2 user: drh tags: trunk)
19:41

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: 56539e1c13 user: drh tags: trunk)

Back out the asserts of check-ins [a500893b6f64aced] and [d9c9fe9f5ad3fc91] as ticket [1b06916e01c82b66] demonstrates a case that refutes them. (check-in: ddb17d92df 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: a982e6434c 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: 8c856404b4 user: dan tags: trunk)

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: 4dbb6e1cb0 user: drh tags: trunk)

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: e2bddcd4c5 user: drh tags: trunk)

Change an unreachable testcase() into an assert() (check-in: 062e00c4d7 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: 862974312e 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.

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: 1e3918ca2f user: drh tags: trunk)

Abort the OP_Savepoint opcode early if a virtual table xSync method fails, perhaps due to an interrupt. (check-in: 672e749aef 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: a89b386056 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: 5b4a88cd3b 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: 2401e04730 user: drh tags: trunk)

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: c29fc21288 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: 47b71a84d1 user: drh tags: two-size-lookaside)

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: fdda76cfb0 user: drh tags: two-size-lookaside, exprlist-size-reduction)

Merge enhancements from trunk. (check-in: 6cb053f99b 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: c6af9f655b user: drh tags: trunk)

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: b7810062ec user: drh tags: trunk)

18:27
Add the SQLITE_SUBTYPE flag, which may be passed to sqlite3_create_window_function() to indicate that the window function uses sqlite3_value_subtype() to check the sub-type of its arguments. (check-in: ba2ebc3a34 user: dan tags: trunk)
17:36
Change the meaning of the SQLITE_SUBTYPE flag so that it indicates that the function may use sqlite3_value_subtype() on its arguments. (Closed-Leaf check-in: 7f424ec9a3 user: dan tags: window-functions-subtype-fix)

14:27
When we play games with COLLATE in order to commute an operator in the WHERE clause processing, be sure not to use the commuted operator to qualify a partial index, as insufficient COLLATE information is preserved to verify that the expression will correctly qualify the index. Ticket [767a8cbc6d20bd68] (check-in: 5351e920f4 user: drh tags: trunk)
2019-09-02

Fix an obsolete comment that defines the meaning of one of the parameters to the sqlite3FindInIndex() subroutine. No changes to code. (check-in: 0c946f0846 user: drh tags: trunk)
00:58
When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression.

2019-08-30
23:56
When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] (check-in: e0d909c740 user: drh tags: trunk)

Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. (check-in: 616f5663b3 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: 84ae41fd2f user: dan tags: trunk)

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: 7f5168a76a user: drh tags: trunk)
10:05
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: 069c2f4c61 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: 12d2cf8871 user: drh tags: dead-end)
20:33

Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d92 user: drh tags: nulls-last)
16:12
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: e3ed2f496f 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: bf875e1a25 user: drh tags: nulls-last)

Early detection out-of-bounds page numbers on the direct-overflow-read optimization gives consistent error messages regardless of whether or not the optimization is enabled. (check-in: b517a52fa3 user: drh tags: trunk)
2019-08-14

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: 07babb0f89 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: 636ca4472c user: drh tags: trunk)

15:06
Fix the sqliteExprImpliesExpr() routine so that it recognizes that "(NULL IS FALSE) IS FALSE" doe not imply "NULL NOT NULL". Ticket [9080b6227fabb466] (check-in: da01ba4fa4 user: drh tags: trunk)
14:35
Add extra test cases related to the previous commit. (check-in: 3c690b2b05 user: dan tags: trunk)

2019-08-09
20:26
Allow the RHS of a row-value IN operator to use a compound query with an ORDER BY clause. (check-in: eaf15d9bae user: drh tags: trunk)
14:54
In shared-schema mode, handle the case where a connection has created a virtual-table object, but is later assigned a different shared-schema object for which the virtual-table schema has not yet been initialized. (check-in: e30c7414fe user: dan tags: reuse-schema)
01:59
Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. (check-in: 68b7f2acf4 user: mistachkin tags: trunk)

19:40
Fix harmless compiler warnings. (check-in: 1eef4ddea9 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: f1cd234c98 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: 83450d1070 user: drh tags: trunk)
16:23
More legacy STAT3 code removed. (Closed-Leaf check-in: 845d2f17de 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: edf45cd7c6 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: 1e17ea2fd1 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: 111e2c73cf user: dan tags: reuse-schema)
01:39
Remove a NEVER() that is reachable from a corrupt database. (check-in: 30e6ee27a9 user: drh tags: trunk)
2019-08-07
19:57
Remove use of the affinity() function from view.test, as it is only available in SQLITE_DEBUG builds. (check-in: 7f2246a17b 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: f5d0436d8d user: dan tags: trunk)
17:45
Eliminate some more cases of redundant sorting in window-function queries. (check-in: 8158d2aca6 user: dan tags: trunk)
13:25
Do not make SQLITE_READ authorizer calls for tables without names, as all such tables will be internal-use-only tables for subqueries and whatnot. (check-in: 193c87fc96 user: drh 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: 17b3d2218c user: dan tags: trunk)
20:55
Improved reuse of file descriptors for which close() is delayed to prevent clearing of posix advisory locks. (check-in: 509c1ba26a user: drh tags: trunk)
20:26
Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. (check-in: 846d2d2d2f 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: bfc29e62ef 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: 9c8c1092a8 user: drh tags: trunk)
15:18
Performance optimization to the new affinity handling logic. (Closed-Leaf check-in: c9724e761b user: drh tags: pending)
15:02
Add a multi-threaded test to threadtest3.c for the feature on this branch. (check-in: 62557fab0d 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: e8234f6939 user: drh tags: pending)
11:45
Add an assert() to the code on this branch. (check-in: fdd44bbb50 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: e15a0977dd user: dan tags: pending)
20:45
Add test cases to this branch. (Closed-Leaf check-in: f37317d81c user: dan tags: tkt-61c853-A)
19:44
Fix the patch on this branch so that it works with sub-queries, as well as views. (check-in: 7480db307c user: dan tags: tkt-61c853-A)
19:34
The second option for [61c853857f40da49]: In this mode, columns of VIEWs and subqueries that are formed by expressions have affinity BLOB rather than affinity none, as has usually been the case for a while. But this mode fixes a couple of corner cases involving query flattening and the push-down optimization where that rule was violated. (Closed-Leaf check-in: 470ac8d50c 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: 09cd0c0c6e user: drh tags: tkt-61c853-A)
18:01
Refactor field Expr.affinity into Expr.affExpr to avoid confusion with other fields and variables named "affinity" and display affExpr it in sqlite3TreeViewExpr() output. (check-in: a29f2a7d07 user: drh tags: trunk)
16:22
Improved detection of corruption on the freeblock list of a btree page. (check-in: 4b00799bdf user: drh tags: trunk)
13:19
Fix a problem with renaming a table when a view or trigger within the schema uses a FILTER with an aggregate function that is not currently registered with the database. (check-in: 2ac0e42f8a user: dan tags: trunk)
12:55
Prevent an fts5 table from being its own content table, or part of a view that is the content table. (check-in: b6d52c9364 user: dan tags: trunk)

Strengthen an assert() in the WHERE clause code generator for the min/max optimization. (check-in: 1bd4b97d64 user: drh tags: trunk)
16:37
Fix a problem with queries of the form "SELECT min(<expr>) ... WHERE <expr>=?" where there is an index on <expr>. Fix for [71e183ca]. (check-in: d465c3eef4 user: dan tags: trunk)
16:17
In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. (check-in: fd598e475d user: drh tags: trunk)
01:40
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: 2660e9292a 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: 49aa344806 user: drh tags: prng-seed-test-control)
2019-08-02

18:43
If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Possible fix for ticket [41866dc37]. (Closed-Leaf check-in: a7277ed062 user: dan tags: tkt-41866dc37)
2019-08-01
22:48
The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. (check-in: 961e2f08c3 user: drh tags: trunk)
15:18
Add new release tests for windows to releasetest_data.tcl. (check-in: 1b330ec24c user: dan tags: trunk)

Update "releasetest_data.tcl" so that it is a standalone script that generates sh or batch scripts to run each tcl test run at release time. Update wapptest.tcl to use it. (check-in: 559c2dd672 user: dan tags: trunk)

Fix the build for when -DSQLITE_SMALL_STACK is used. (check-in: b9eda2249a user: drh tags: trunk)
14:22
Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. (check-in: 89bf0399e8 user: drh tags: trunk)
01:17
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] (check-in: a871d69c6d 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)

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

Fix harmless compiler warning in the session extension. (check-in: dff823ca8b user: mistachkin tags: trunk)
01:22
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: d612fb7873 user: drh tags: trunk)
2019-05-15
18:42

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: 9b0915272f user: drh tags: trunk)
16:57

Ensure that the sqlite3BtreeLast() interface initializes the *pRes return to zero if the cursor is already sitting on the last entry of the table. Manuel Rigger found the obscure test case for which this makes a difference. (check-in: ebe4845cd0 user: drh tags: trunk)
23:53

Remove an ALWAYS() that was previously added by check-in [a0819086] but which turns out can sometimes be false. (check-in: ad8fc5d8b4 user: drh tags: trunk)
03:34
Remove a NEVER() that was added in the previous check-in [a0819086a521f] because it is in fact reachable. (check-in: 74eba2558a user: drh tags: trunk)
00:17

2019-05-07
20:06
Generate all records for INSERT or UPDATE prior to running foreign key constraint checks, since the FK checks might modify the datatype of registers used to generate the records. Fix for ticket [e63cbcfd3378afe6980d6]. (check-in: 3c75605b46 user: drh tags: trunk)
19:44

In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. (check-in: 5a8a23ee5f user: drh tags: trunk)
01:29
New testcase macros to ensure that MEM_IntReal is fully tested. (Closed-Leaf check-in: 8b8ef445cc user: drh tags: int-real)
2019-05-03
21:17
Add the SQLITE_TESTCTRL_RESULT_INTREAL test-control and use it to create the intreal() SQL function in testfixture. Write a few simple tests to prove this all works. TH3 will hold most of the INTREAL tests, probably. (check-in: c983873132 user: drh tags: int-real)
19:34
Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. (check-in: 3a16ddf91f user: drh tags: trunk)

2019-05-02
21:36
Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. (check-in: dba836e31c user: drh tags: int-real)
17:45

Correctly initialize the loadable extension thunk. (check-in: 4fca46ded7 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: 9cac5ac145 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)

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)

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)
00:48
Add new APIs to the extension loading mechanism. (check-in: 6f122faf8a user: drh 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: fa37cf9a6a 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)
17:07
Add an extra IO-error test to windowfault.test. (check-in: 5b8c44cd39 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: 27160df7b3 user: drh tags: value_frombind)

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: f5752517f5 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: 040d5d515b user: drh tags: trunk)

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: ab76e3a90e user: drh tags: value_frombind)

Show the pointer address for Window objects in the TreeView display. (check-in: 1ae70ad2ff 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: d6a0743342 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: ec2f207ded user: drh tags: trunk)

22:05
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)

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
Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. (check-in: b99f8512c0 user: drh tags: trunk)

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

20:46
Implement the EXCLUDE clause for window frames. (check-in: 9b43c3ee2e user: dan tags: window-functions)

Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af521 user: dan tags: trunk)
00:21
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

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)
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)

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)

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)
2019-02-16
22:45
Fix an assert() that might be false for a corrupt database. (check-in: 0cfb888723 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)
18:38
Change the name of the SQLITE_OPEN_REUSE_SCHEMA flag to SQLITE_OPEN_SHARED_SCHEMA. (check-in: 7257fcc8c9 user: dan tags: reuse-schema)
17:59

Add documentation file doc/shared_schema.md to describe the change on this branch. (check-in: a5f8067dde user: dan tags: reuse-schema)
15:56
Merge latest trunk into this branch. (check-in: 577d163836 user: dan tags: reuse-schema)
15:27
Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). (check-in: aa61435a4c user: drh tags: trunk)
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)
16:58
Further performance improvements to btreeInitPage(). (check-in: 93ae382e97 user: drh tags: trunk)
15:51
Increase the version number to 3.28.0 for the next release cycle. (check-in: 6eb38c59a8 user: drh tags: trunk)
12:25
Register the "vfsstat" virtual table immediately when loading the vfsstat.c extension. (check-in: 9bd92afd0c user: drh tags: trunk)
