| 19:27 | Improve the performance of ANALYZE when SQLITE_ENABLE_STAT4 is defined. (check-in: 737a824440 user: dan tags: trunk) | |
| 18:53 | Improvements to PRAGMA integrity_check. Verify CHECK constraints. Verify NOT NULL constraints even on table that lack indexes. Verify CHECK and NOT NULL constraints with PRAGMA quick_check. (check-in: aa02bd3c95 user: drh tags: trunk) | |
| 18:04 | Cleanup and simplification of the output row count limit control of PRAGMA integrity_check. (Closed-Leaf check-in: 5af7d72ed9 user: drh tags: integrity-check-improvements) | |
| 15:11 | Fix integrity_check so that it verifies NOT NULL constraints even for tables that have no indexes. Enhance quick_check so that it verifies NOT NULL and CHECK constraints. (check-in: 5264844b06 user: drh tags: integrity-check-improvements) | |
| 14:15 | Enhance "PRAGMA integrity_check" so that it verifies CHECK constraints. (check-in: 549bae0856 user: drh tags: integrity-check-improvements) | |

| 21:24 | In sqlite3VdbeHalt(), return as soon as possible if Vdbe.magic!=VDBE_MAGIC_RUN. This makes sqlite3_reset() slightly faster in some cases. (check-in: 80adc0cb4e user: dan tags: trunk) | |
| 17:52 | Fix an FTS5 problem that could cause a crash when certain queries were interrupted using sqlite3_interrupt(). (check-in: e400909f31 user: dan tags: trunk) | |
| 15:27 | Very small enhancement to dispatch speed for SQL functions. (check-in: 3c3228ed16 user: drh tags: trunk) | |
| 14:04 | The VDBE cycle counts for the sqlite3_progress_handler() callback are now cumulative. Leftovers from the previous statement are applied to the next statement. (Leaf check-in: 7a62fc6abc user: drh tags: cumulative-progress-count) | |
| 13:29 | Proof of concept for a "PRAGMA vdbe_cycle_limit=N" command. When N>0, invoke sqlite3_interrupt() whenever any byte code program uses more than N virtual machine cycles. (Leaf check-in: 9626b41e6e user: drh tags: vdbe_cycle_limit) | |

| 23:32 | Correct a harmless typo in the previous check-in. (check-in: 1589db012e user: mistachkin tags: trunk) | |
| 19:13 | Avoid unsigned integer overflows for SQLITE_WIN32_HEAP_INIT_SIZE when the Win32 heap subsystem is used with very large values of SQLITE_DEFAULT_CACHE_SIZE and/or SQLITE_DEFAULT_PAGE_SIZE. (check-in: 96b6a98e5e user: mistachkin tags: trunk) | |
| 14:30 | Small grammar simplification. (check-in: 0d8a868acd user: drh tags: trunk) | |
| 13:11 | Merge fixes from trunk. (check-in: ff213f2ef5 user: drh tags: auto-analyze) | |

| 22:52 | Updated comments. No code changes. (check-in: e842ad391e user: drh tags: auto-analyze) | |
| 20:05 | Add an optimization to OP_Column to speed up sequential OP_Column instructions that read earlier fields from the same cursor. Attempt to reorder OP_Column opcodes so as to take advantage of this. (Leaf check-in: c1adf95958 user: dan tags: sort-column-opcodes) | |
| 15:58 | Add the OP_SqlExec opcode and use it to implement "PRAGMA analyze_as_needed", invoking ANALYZE subcommands as necessary. This simplifies the implementation. (check-in: d386015f5e user: drh tags: auto-analyze) | |
| 13:47 | Add the SQLITE_BUG_COMPATIBLE_20160819 compile-time option to omit the error message when an unrecognized argument is provided to the VACUUM command. (check-in: 491814272d user: drh tags: trunk) | |
| 02:42 | Fix errors in the table resize detection. (check-in: 4229caec0b user: drh tags: auto-analyze) | |
| 02:19 | In the analyze_as_needed pragma, avoid running unnecessary OP_LoadAnalysis and OP_Expire opcodes. Make the analyze_as_needed pragma responsive to the schema name. (check-in: 882599a4a7 user: drh tags: auto-analyze) | |
|

| 23:52 | Fix the #endif location for an #ifndef SQLITE_UNTESTABLE macro in the command-line shell. (check-in: 8cc9d74c17 user: drh tags: trunk) | |
| 21:23 | Increase the estimated cost of sorting when sorting wide results sets, to account for the extra storage space and I/O required for the external sort. (Leaf check-in: 38298ef923 user: drh tags: apple-increased-sorting-cost) | |
| 19:24 | The analyze_as_needed pragma now responds to table size growth and will automatically rerun the analysis after each 10x size increase. (check-in: bfbdd07409 user: drh tags: auto-analyze) | |
| 16:26 | Add the "PRAGMA analyze_as_needed" command. (check-in: e93db23731 user: drh tags: auto-analyze) | |
| 15:26 | Set the TF_StatsUsed flag on tables when the query planner outcome is affected by the sqlite_stat1 data. Also, change the column names of the "PRAGMA stats" command so that they are not keywords. (check-in: fb2b8ae831 user: drh tags: auto-analyze) | |
| 13:38 | Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats". These are all preliminary steps toward a "PRAGMA analyze_ifneeded;" feature. (check-in: 85026c8ee1 user: drh tags: auto-analyze) | |
| 02:07 | Merge fixes from trunk. (Leaf check-in: 662e8ccf7e user: drh tags: increased-sorting-cost) | |
| 02:04 | Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. (check-in: 218b2bbb0d user: drh tags: trunk) | |
| 01:43 | Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. (check-in: 8a03be1dc4 user: drh tags: trunk) | |

| 21:29 | Increase the estimated cost of sorting when sorting wide results sets, to account for the extra storage space and I/O required for the external sort. (check-in: aa0703e5ce user: drh tags: increased-sorting-cost) | |
| 20:52 | Change the name of WhereInfo.pDistinctSet to pResultSet, since it is now used for more than just DISTINCT processing. (check-in: 9fc5cd505f user: drh tags: trunk) | |
| 17:18 | Change two MallocZero() calls into MallocRaw() to avoid unnecessary memset(). (check-in: ff5e733cbf user: drh tags: trunk) | |
| 16:26 | Fix a comment on a field of the ExprList object. No changes to code. (check-in: bb8e264227 user: drh tags: trunk) | |
| 15:57 | Increase Table.tabFlags from 8 to 32 bits. (check-in: 7e14044c65 user: drh tags: trunk) | |
| 15:06 | Remove two redundant initializations from the virtual table logic. (check-in: 6bd82b95a6 user: drh tags: trunk) | |
| 14:48 | Always use the IsVirtual() macro to determine if a Table object is a virtual table. Slightly smaller and faster code. (check-in: 6affb1c89d user: drh tags: trunk) | |
| 14:02 | Merge recent enhancements from trunk. (check-in: 325ccfa95e user: drh tags: est_count_pragma) | |

| 22:36 | Query planner optimization to detect empty tables in a join early and bail out without doing excess work. (check-in: 58797e9baf user: drh tags: trunk) | |
| 18:30 | Minor enhancement to mutex tracing on Win32. (check-in: 830b923567 user: mistachkin tags: trunk) | |
| 17:47 | simple test cases for carray_asc. (Leaf check-in: 1d4759c17c user: drh tags: carray_asc) | |
| 16:11 | Add the companion "carray_asc" table-valued function to the carray extension. (check-in: a2b4f60b33 user: drh tags: carray_asc) | |
| 16:04 | Bummer. Checked this in as a branch off of the wrong branch.... Was: Add the companion "carray_asc" table-valued function to the carray extension. (Closed-Leaf check-in: 396b9d99ae user: drh tags: mistake) | |
| 15:11 | Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. (check-in: 8d3f485d86 user: drh tags: branch-3.17) | |
| 15:09 | Remove the CLANG_VERSION macro, since we have learned that version numbers in clang are "marketing" and are inconsistent and unreliable. Builds using clang will still use the GCC_VERSION macro since clang works hard to be gcc compatible. (check-in: 810d29320b user: drh tags: trunk) | |
| 04:16 | Further reforms to Tcl_*Alloc() usage. (check-in: ee1e689633 user: mistachkin tags: trunk) | |
| 01:39 | In the blob test code, avoid crashing on low-memory systems by using Tcl_AttemptAlloc(). (check-in: 1d267757a8 user: mistachkin tags: trunk) | |
| 01:02 | Make SQLITE_GET_MUTEX_TIME a proper noop on non-Win32/non-POSIX. (Leaf check-in: 4ca2b2f8f5 user: mistachkin tags: mutexDbg2) | |
| 00:52 | Another compilation fix for POSIX. (check-in: 82ef47ea88 user: mistachkin tags: mutexDbg2) | |
| 00:45 | Make fine time granularity work on POSIX. (check-in: 79057716d9 user: mistachkin tags: mutexDbg2) | |
| 00:02 | Compilation fix for POSIX. (check-in: 9964ad245f user: mistachkin tags: mutexDbg2) | |
