21:17
More fixes for different window frame types. (check-in: 2c85668a user: dan tags: exp-window-functions)
20:04
Merge the ability to plan virtual table queries using overloaded functions. (check-in: 2c2a202c user: drh tags: rtree-geopoly)
18:03
Experimental change that allows overloaded functions to be analyzed by the xBestIndex method and used by the xFilter method of a virtual table. (Leaf check-in: a353b1d7 user: drh tags: vtab-func-constraint)
16:00
Store application-defined function names as lower-case to avoid the need for case conversions before calling xFindFunction on virtual tables. Avoid using lookaside to store the destructors for application defined functions, as lookaside should be reserved for transient allocations. (check-in: 777189ce user: drh tags: trunk)
13:55
Add a single sentence of documentation about the virtual table scan flags. No changes to code. (check-in: 27b4fa5d user: drh tags: trunk)
12:21
Minor correction. (check-in: f20d9a99 user: drh tags: rtree-geopoly)

18:18
Adjust the bitvec related sqlite3_log messages added by [9527089b]. (check-in: a7e0e7a4 user: dan tags: begin-concurrent)
16:51
Add extra test cases for deferred page allocation. (check-in: 9df01957 user: dan tags: begin-concurrent)
16:15
Fix a problem with deferred page allocation in transactions that revert page allocations by savepoint rollbacks. (check-in: a4a3bbe6 user: dan tags: begin-concurrent)

2016-05-26
20:56
Add a new OP_SeekRowid opcode, that combines the functions of OP_MustBeInt and OP_NotExists. This makes the code slightly smaller and faster. (check-in: ffe80a1b user: drh tags: trunk)
20:52
Add further instrumentation to the bc_test1.c test app. (check-in: 5528de4a user: dan tags: begin-concurrent)

20:31
Avoid a buffer overread when comparing against a corrupt record that spans at least one overflow page. (check-in: 62a5b363 user: dan tags: trunk)
20:07
Avoid branching on an uninitalized variable when comparing SQL values with the undefined serial types 10 and 11 (which only appear in corrupt databases). (check-in: b4a45d3b user: dan tags: trunk)
19:08
The "make fuzztest" target now uses fuzzcheck instead of fuzzershell. Test data is added for database fuzz testing. (check-in: 5e3e410b user: drh tags: trunk)
19:01
Merge accidental fork. (Closed-Leaf check-in: e85628e3 user: dan tags: test-using-fuzzcheck)
18:58
Fix a one-byte buffer overread that may follow a syntax error while preparing an SQL statement. (check-in: 07500393 user: dan tags: test-using-fuzzcheck)
18:58
Fix fuzzcheck so that it responds correctly to the TEST_FAILURE environment variable. (check-in: 76770c9e user: drh tags: test-using-fuzzcheck)
18:22
Simplifications and minor optimizations to fts5 prefix queries that cannot use a prefix index. (check-in: aef89d9f user: dan tags: fts5)
18:15
The "make fuzztest" target now uses fuzzcheck instead of fuzzershell. (check-in: 4a5f6f1f user: drh tags: test-using-fuzzcheck)
17:57
Enhance fuzzcheck with the ability to store descriptions in each source database and to run multiple source databases in a single invocation. (check-in: 193364c8 user: drh tags: trunk)
17:33
Add a cast to one side of the test added by [97806a78] in order to avoid a signed/unsigned comparison warning. (check-in: 5b46d2a7 user: dan tags: trunk)
17:29
Avoid using a zero-sized array within a struct in fts3 code. (check-in: b05cae36 user: dan tags: trunk)
16:12
Fix another bug in the in-memory VFS for fuzzcheck. (check-in: 16878a31 user: drh tags: trunk)
14:57
Update test cases in corruptI.test so that they work with both SQLITE_ENABLE_OVERSIZE_CELL_CHECK and SQLITE_DEFAULT_AUTOVACUUM builds. (check-in: 22a14663 user: dan tags: trunk)
12:18
Return SQLITE_CORRUPT to the user if an attempt is made to add database page 1 to the free page list. (check-in: 68876003 user: dan tags: trunk)
11:53
Fix a problem with ignoring UNIQUE constraints on WITHOUT ROWID tables rendered redundant by the PRIMARY KEY. (check-in: 3b936913 user: dan tags: trunk)
03:31
Silence harmless compiler warnings when building the command line utilities with MSVC. (check-in: d26060c4 user: mistachkin tags: trunk)
03:24
Add fuzzcheck to makefile clean targets. Also, for consistency, replace a few tabs with spaces. (check-in: eda2a437 user: mistachkin tags: trunk)
00:28
Add the --result-trace option to fuzzcheck, and other interface enhancements. (check-in: c415bb7b user: drh tags: trunk)

Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. (check-in: 42705bab user: drh tags: trunk)
15:06
Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de0073 user: drh tags: trunk)

15 Years Ago (more context)

2005-05-26
16:23

14:41
If SSE is enabled, set the P1 field of OP_AggInit instructions to the number of arguments that will be passed to the aggregate function. (CVS 2484) (check-in: 7f67b9f0 user: danielk1977 tags: trunk)
12:37
Fix minor problems with the SSE hooks. (CVS 2483) (check-in: 3516ca29 user: danielk1977 tags: trunk)
