200 most recent check-ins using file test/func4.test version 6beacdfc

2023-11-29
16:26
Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (Leaf check-in: f10d4fc4 user: drh tags: branch-3.28)
16:07
Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a7 user: drh tags: branch-3.28)
2023-10-19
21:05
Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28)
2023-09-15
20:04
Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28)
2023-02-26
11:52
In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e user: drh tags: branch-3.28)
2023-02-16
21:01
Fix an #ifdef that uses a different macro name from the main branch. (check-in: ad6ac5d3 user: drh tags: branch-3.28)
19:04
Back-port omit-unused-subquery-column enhancements into the 3.28 branch. (check-in: 57a4e91f user: drh tags: branch-3.28)
14:29
Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 0163b697 user: drh tags: branch-3.28)
01:29
Do not compute unused result columns of subqueries. This optimization will potentially resolve the performance optimization request of [ticket baa5bb76c35a124c]. (Closed-Leaf check-in: 0c21b6a5 user: drh tags: branch-3.26)
01:21
Update test cases so that they work with TCL 8.7 and later. (check-in: e9b762de user: drh tags: branch-3.26)
2023-02-15
13:00
Update the configure script so that it contains the correct version number. (check-in: a7cbf308 user: drh tags: branch-3.26)
2022-10-24
13:50
Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de user: drh tags: branch-3.28)
2022-10-19
11:22
If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)
2022-09-27
17:00
Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14)
2022-09-01
10:41
In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)
2022-08-10
17:03
Merge the branch-3.28a fixes into branch-3.28. (check-in: ba6bf331 user: drh tags: branch-3.28)
2022-08-09
20:22
Fix a rounding error caused by scalar->logarithm->scalar conversion when using stat4 data to estimate some range scans. (check-in: 68d86f2b user: drh tags: branch-3.28)
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. (Closed-Leaf check-in: d2e67220 user: dan tags: branch-3.28a)
2021-07-12
14:38
Fix a defect in the query-flattener optimization identified by ticket [8f157e8010b22af0]. This fix is associated with CVE-2020-15358. (check-in: 9e001b63 user: dan tags: branch-3.28a)
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. (check-in: 263293f1 user: drh tags: branch-3.28)
2020-10-02
13:57
Import further corner-case fixes for the in-scan-vs-index or OP_SeekScan optimization from trunk. (check-in: c144d640 user: drh tags: branch-3.28)
12:11
For the OP_SeekScan optimization, the OP_IdxGT does not necessarily come right after the OP_SeekGE. So use the P2 operand of OP_SeekScan to point to the first instruction after OP_IdxGT. Problem found by dbsqlfuzz. (check-in: ec37744c user: drh tags: branch-3.28)
02:07
Disable the OP_SeekScan opcode of the in-scan-vs-index optimization when in PRAGMA reverse_unordered_selects mode, as the OP_SeekScan only works with forwards scans. Thanks to OSSFuzz for pointing out the problem to us. (check-in: 9a1cdf7e user: drh tags: branch-3.28)
2020-09-30
18:22
Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: f07ac3fb user: drh tags: branch-3.28)
2020-09-01
02:02
Improvements to the IN-early-out optimization so that it works more efficiently when there are two or more indexed IN clauses on a single table. (check-in: 49b7631e user: drh tags: branch-3.28)
2020-08-31
19:19
An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. Update: Experiment did not work out. (Closed-Leaf check-in: 8301da31 user: drh tags: branch-3.28-in-early-out-fail)
2020-08-17
21:03
When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. (check-in: 0ecda433 user: dan tags: branch-3.28)
2020-05-06
18:46
Provide the SQLITE_DEFAULT_LEGACY_ALTER_TABLE compile-time option. (check-in: b2325a6e user: drh tags: branch-3.28)
2020-04-04
00:29
In the push-down optimization, do not substitute columns that have previously been identified as being constant by the propagate-constants optimization. Fix for ticket [51166be0159fd2ce]. Also, avoid factoring out constant expressions on the LHS of an IN(...) operator, as the IN(...) operation may affect the affinity of these values. Fix for [fd1bda016d1]. (Leaf check-in: 43612157 user: drh tags: branch-3.31)
2020-04-03
20:14
Restore an #if block inadvertently removed via check-in [9c77bfe41e]. (check-in: bf6bcfc1 user: mistachkin tags: branch-3.31)
13:39
Do not suppress errors when resolving references in an ORDER BY clause belonging to a compound SELECT within a view or trigger within ALTER TABLE. Fix for ticket [a10a14e9b4ba2]. Also, in the event of a semantic error in an aggregate query, early-out the resetAccumulator() function to prevent problems due to incomplete or incorrect initialization of the AggInfo object. Fix for ticket [af4556bb5c285c08]. (check-in: b6467491 user: drh tags: branch-3.31)
13:29
Fix a case when a pointer might be used after being freed in the ALTER TABLE code. Fix for [4722bdab08cb1]. (check-in: 52f800fa user: drh tags: branch-3.31)
2020-03-10
19:23
Prevent the read-only expressions held in the schema from being passed down into code generating subroutines where they might be changed. Pass a copy of the expression instead. (check-in: 2b750b0f user: drh tags: branch-3.31)
2020-02-27
12:33
Backport the change that allows the filename passed into the xFullPathname to be used as an argument to sqlite3_uri_parameter(). (check-in: 9c77bfe4 user: drh tags: branch-3.31)
2020-02-06
11:08

2020-02-01
17:38
Fix the comment display for the OP_Function opcode. And at the same time, improve the comment generating logic to make use of the newer sqlite3_str_appendf() interface. (check-in: 4248980a user: drh tags: trunk)
14:29
Fix a problem in sqlite3CodecQueryParameters() that was introduced by the query parameter encoding changes for the 3.31.1 release. (check-in: 1240ee4f user: drh tags: apple-osx)
14:20
Merge the sqlite3CodecQueryParameters() fix into trunk. (check-in: a812f533 user: drh tags: trunk)
13:30

2020-01-29
15:03
Fix a problem with the processing of IN(...) constraints handled by virtual table implementations that do not set the "omit" flag when the virtual table column contains at least one NULL value. (check-in: dcb48387 user: dan tags: trunk)
13:56
Add a test case for commit [ffd8bb93]. (check-in: bcd5b37b user: dan tags: trunk)
13:50
Remove a NEVER() that is in fact reachable. Test cases in dbsqlfuzz and TH3. (check-in: ffd8bb93 user: drh tags: trunk)

2020-01-28
20:27
Faster decoding of 32-bit variable-length integers in cases were we do not need to know the number of bytes in the encoding. (check-in: 59a31b16 user: drh tags: trunk)
20:09
Small performance improvement to the key-comparision routine for strings. (check-in: 41454499 user: drh tags: trunk)
18:09
Reinstate the optimization of converting "a IN (C)" into "a=C" but only if C is a constant. If the RHS is a table column, the complications of managing affinity and collations become too involved to mess with. (check-in: 8ac26a23 user: drh tags: trunk)
16:55
Fix a 4 byte OOB read in test_multiplex.c. (check-in: 91214891 user: dan tags: trunk)

Version 3.31.1 (check-in: 3bfa9cc9 user: drh tags: trunk, release, version-3.31.1)
17:09
Update the version number to 3.31.1. (check-in: 6fb9a8fb user: drh tags: trunk)
14:40
Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout. Technically, this is a misuse of SQLite by the 3rd-party software, but we want to avoid unnecessary breakage. (check-in: 34ab7606 user: drh tags: trunk)
2020-01-23
15:00

2020-01-21
21:01
Begin adding instrumentation to record and report on the set of key-ranges a concurrent transaction reads from the database. (check-in: c39e3c14 user: dan tags: begin-concurrent-report)
16:31
Update test file exclusive.test so that it works with the "journaltest" permutation. (check-in: 4daf94d8 user: dan tags: trunk)
16:23
Fix a problem with using views in SQLITE_OMIT_VIRTUAL_TABLE builds. Also some test case fixes required for the same builds. (check-in: 934ee8bd user: dan tags: trunk)
15:01
Fix a case in fts3auto.test that fails for SQLITE_DISABLE_FTS4_DEFERRED builds. (check-in: d241055e user: dan tags: trunk)
14:42

13:40
Fix a problem in the userauth extension causing it to occasionally set "PRAGMA count_changes" (and some others) to true. (check-in: 3a62f642 user: dan tags: trunk)
12:29
Fix the series.c and spellfix.c extensions to use SQLITE_VTAB_INNOCUOUS correctly. Fix the documentation on sqlite3_vtab_config() to take into account SQLITE_VTAB_INNOCUOUS and SQLITE_VTAB_DIRECTONLY. (check-in: 9265cb7f user: drh tags: trunk)
01:45
Improvements to the autoconf TEA Makefile for MSVC. (check-in: cffcf12f user: mistachkin tags: trunk)
2020-01-20
15:32
Merge recent fixes from trunk. (check-in: 9c920bba user: drh tags: reuse-schema)
14:42
In the fuzzcheck test program, reduce the default expression depth limit from 1000 to 500 to avoid stack-overflow problems when running stress tests using clang ASAN. (check-in: 63d886f4 user: drh tags: trunk)
2020-01-19
20:37
Enhancement to the CLI to allow the ".parameter init" command to work even if defensive mode is turned on. (check-in: 4d462550 user: drh tags: trunk)
2020-01-18

Documentation improvements. (check-in: 535afe15 user: drh tags: trunk)
22:20
In the TCL interface, add the ability to change the SQLITE_DBCONFIG_TRUSTED_SCHEMA setting using the "db config" method. (check-in: 1accfa8c user: drh tags: trunk)
21:34
Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should not be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526 user: drh tags: trunk)
19:58
Fix a couple of test case issues on this branch. (check-in: 9830a44b user: dan tags: reuse-schema)
19:46
Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. (check-in: cca43778 user: drh tags: trunk)
19:07
Disable a redundant test case that uses a very large stack, and hence is unable to run with -fsanitize=undefined,address. (check-in: 3c63f68e user: drh tags: trunk)
19:02
Fix harmless compiler warning seen with MSVC. (check-in: cd0437ba user: mistachkin tags: trunk)
18:59
Have this branch call sqlite3LockAndPrepare() instead of sqlite3Prepare() when parsing SQL for new schema objects in order to ensure that schemas are released as soon as possible. (check-in: 7a4ec579 user: dan tags: reuse-schema)
14:50
Add extra front margin to the fake empty filename returned by sqlite3PagerFilename() for an in-memory or TEMP database. (check-in: fee94567 user: drh tags: trunk)
13:53
Fix the VDBE so that it correctly handles the sequence of operations OP_OpenEphemeral, OP_OpenDup, OP_OpenEphemeral, and OP_OpenDup in that order on the same cursor. (check-in: a1be6ee0 user: drh tags: trunk)
2020-01-17
23:27
Fix a typo in a comment. No code changes. (check-in: 4363f69c user: drh tags: trunk)
21:12
The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f31490 user: drh tags: trunk)
19:14
Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. (check-in: 7584e4b6 user: drh tags: trunk)
16:47
Improved rounding in the 'unixepoch' feature of the date and time functions. (check-in: c9abf1bd user: drh tags: trunk)
15:45
Update test script instrfault.test to account for the fact that bound blob values cast to text values are now intepreted using the text encoding of the database, instead of always as utf-8. (check-in: 4d6cb288 user: dan tags: trunk)
15:33
More restrictions on changes to shadow tables when in defensive mode. (check-in: b302b260 user: drh tags: branch-3.28)
15:24
Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 3d13fbf2 user: drh tags: branch-3.28)
14:56
Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f user: drh tags: branch-3.28)
14:30
Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c6 user: drh tags: branch-3.28)
14:18
Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22)
11:18
Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e user: dan tags: trunk)
2020-01-16
17:53
New testcase() macros in select.c, for coverage of the change from two check-ins ago. (check-in: 52206488 user: drh tags: trunk)
16:32
Add the SQLITE_FCNTL_CKPT_DONE file-control for the use of custom VFSs. (check-in: 3cc39e50 user: dan tags: trunk)
16:12
Do not allow the constant-propagation optimization to apple to ON/USING clause terms as it does not help and it might cause downstream problems. (check-in: 1bc783da user: drh tags: trunk)
13:02
Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. (Leaf check-in: f8801ffd user: drh tags: close-cursor-faster)
12:25
Fix an SQL syntax error in the comment on the omit-left-join optimization. No changes to code. (check-in: 86b5e5a2 user: drh tags: trunk)
11:51
Clean up the definitions of the TERM_ constants in the code generator. Formatting only - no logic changes. (check-in: af06f80a user: drh tags: trunk)
2020-01-15
17:18
Fix the assert_schema_state_ok() routine so that it correctly ignores ATTACH-ed database that failed to open due to an error. (check-in: 1194a42a user: drh tags: reuse-schema)
16:20
Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. (check-in: 03b003c9 user: drh tags: trunk)
14:26
Merge all recent enhancements and fixes from trunk. (check-in: f7839178 user: drh tags: reuse-schema)

Merge fixes and enhancements from trunk into begin-concurrent. (check-in: 95ba2f50 user: drh tags: begin-concurrent)
12:49
Merge all recent enhancements and fixes from trunk into the apple-osx branch. (check-in: dadedf41 user: drh tags: apple-osx)
2020-01-14

Fix the urifuncs.c extension (used for testing and debugging only) so that the sqlite3_filename_database() SQL function and its siblings correctly handle an invalid schema name passed in as the argument. (check-in: 3d7434a9 user: drh tags: trunk)
16:39
Remove an ALWAYS on a branch for improved database corruption detection in btree.c:freeSpace(). Test case found by dbsqlfuzz. (check-in: 54bf0481 user: drh tags: trunk)
16:33
Add the new noop_nd() debugging function to the noop.c extension. (check-in: 72911fb1 user: drh tags: trunk)
13:24
For the showdb utility program, more accurate detection of when the database is in autovacuum mode for the "pgidx" subcommand. (check-in: 9ce2192b user: drh tags: trunk)

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: 3e3c60d8 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. (check-in: 0e468aa6 user: drh tags: trunk)
22:20
Remove an incorrect assert(). Fix for ticket [614b25314c766238] (check-in: 6a999c5a user: drh tags: trunk)

21:08
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: fd7bcc53 user: drh tags: trunk)
20:27
Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). (Closed-Leaf check-in: 9a70ff43 user: drh tags: enhanced-uri)
16:08
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)

20:33
Fix a harmless compiler warning. (check-in: edbf911f user: drh tags: trunk)
20:11

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)

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)

Merge all fixes and enhancements from trunk. (check-in: b878c30f user: drh tags: new-security-options)
19:14
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)

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)

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)
