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)
2021-02-11
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)
2020-04-04
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].

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

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)
02:57
The sqlite3ExprCodeFactorable() routine should make a copy of non-factorable expressions, as they might be coming from a DEFAULT or generated column in a table constraint. (check-in: a2d6f108 user: drh tags: trunk)
01:24
Background work for experiments trying to enhance ANALYZE so that it runs off of samples of the entire index and does not need to read the entire index. (check-in: 29d1cc5c user: drh tags: approximate-analyze)
2020-03-09
21:00
Report on pages, as well as keys, read and written by BEGIN CONCURRENT transactions. (check-in: b661ccc8 user: dan tags: begin-concurrent-report)

16:13
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]. (check-in: 4a585189 user: drh tags: trunk)
14:19
When printing the OP_CollSeq opcode for EXPLAIN listings, include the text encoding with the name of the collating sequence. (check-in: eb5c1b77 user: drh tags: trunk)

20:04
Remove an invalid assert() on the debugging logic that checks to ensure that register values are not used after they go stale. Ticket [d165ad781b39d574]. (check-in: bd94d7d0 user: drh tags: trunk)
01:16

15:53
In the CLI, add the ".oom" command for debugging builds. (check-in: 9c3136a7 user: drh tags: trunk)
2020-02-28
16:04
The RTREE extension behaves as if data columns have type REAL, so we should actually declare them as REAL so that automatic indexes handle them correctly. Ticket [e63b4d1a65546532] (check-in: 85a9b6a9 user: drh tags: trunk)
2020-02-27
17:16
In sqlite3changeset_apply(), ensure that DELETE and UPDATE changes are always executed on main database tables, not similarly named temp tables, as documented. INSERT statements are already being handled correctly. (check-in: f71a13d0 user: dan tags: trunk)
16:21
Fix harmless compiler warnings from MSVC. (check-in: 951b39ca user: drh tags: trunk)

Merge latest trunk changes into this branch. (check-in: 3f5650aa user: dan tags: reuse-schema)
15:07
Optimization for "SELECT min(x) FROM tbl" where "x" is indexed and NOT NULL. This also allows similar queries on NOT NULL virtual table columns to be optimized. (check-in: 59726777 user: dan tags: trunk)
13:54
Extra zero terminators on the end of the blank filename returned by sqlite3PagerFilename() for an in-memory database. This helps the result work better with sqlite3_filename_journal() and similar functions. (check-in: 63e533d2 user: drh tags: trunk)
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)
11:32
Ensure that the filename passed into the xFullPathname method of the VFS is acceptable as an argument to sqlite3_uri_parameter(). The interface spec does not guarantee this, but it has been so historically and some applications have come to depends on it. (check-in: bfb09371 user: drh tags: trunk)
2020-02-25
20:05
Update the fuzzcheck test module so that it avoids inserting text values that contain embedded NULs in the XSQL table. Fix some legacy entries in the test/fuzzdata8.db that had embedded NULs. Add in new dbsqlfuzz cases that have accumulated over on the dbsqlfuzz project for a while. (check-in: 47d4240c user: drh tags: trunk)
2020-02-24
17:05
If STAT4 determines that a WHERE clause term that is not used by an index has very high probability of being true, then do not use that term to reduce the estimated output row count. (check-in: 40739c79 user: drh tags: trunk)
16:46
Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term. (Closed-Leaf check-in: 4558163b user: drh tags: stat4-truthprob)
13:35

2020-02-22
18:27
Do not activate the truthProb adjustment mechanism if the truth probability is less than the heuristic value, as there could be correlations unknown to stat4. Also add additional tracing output to make truthProb adjustments more visible. (check-in: c535fea1 user: drh tags: stat4-truthprob)
17:32
Add new test file analyzeG.test, containing a test for the change on this branch. (check-in: 243ab185 user: dan tags: stat4-truthprob)
16:58
When stat4 information is available, try to use it to improve the truth probability of WHERE clause terms that do not participate in the index. (check-in: 1babd6ec user: drh tags: stat4-truthprob)
13:01
In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set. Ticket [aa4378693018aa99] (check-in: f02030b3 user: drh tags: trunk)
2020-02-20
14:11

Increase the default upper bound on the number of parameters in a single SQL statement to 32766 (from 999). (check-in: 2def7569 user: drh tags: trunk)
11:57
When determining whether an == or IS constraint in a WHERE clause makes an ORDER BY term redundant, consider the collation sequence used by the == or IS comparison, not the collation sequence of the comparison expression itself.

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.

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

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)

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)

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

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

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)

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)

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)

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)
