| 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) | |

| 20:00 | Enable the SQLITE_ENABLE_NULL_TRIM option for WITHOUT ROWID tables. (check-in: 54836270c9 user: drh tags: trunk) | |
| 16:30 | More realistic lengths of string values in speedtest1 with --testset orm. (check-in: e4731fd65f user: drh tags: trunk) | |
| 15:58 | Fix a testcase number on the ORM testset of speedtest1. (check-in: 58b2f911ee user: drh tags: trunk) | |
| 15:57 | Add the new "--testset orm" to the speedtest1 utility. (check-in: 1836adc1d1 user: drh tags: trunk) | |

| 13:35 | Change all legacy instances of "#if SQLITE_DEBUG" to "#ifdef SQLITE_DEBUG" for consistency. (check-in: 670f10b242 user: drh tags: trunk) | |
| 13:26 | Fix typos in using the MSVC_VERSION macro. (check-in: f3b65926b1 user: drh tags: trunk) | |
| 13:20 | Avoid a duplication #define in FTS5 (check-in: c447441cff user: drh tags: trunk) | |

| 15:02 | Ensure that indexed expressions with collating sequences are handled correctly. Fix for ticket [eb703ba7b50c1a5] backported from trunk. (check-in: b2e49ae36b user: drh tags: branch-3.17) | |
| 14:59 | Fix indexes on expressions so that they can be actually used with a COLLATE clause. (check-in: e464b919f7 user: drh tags: trunk) | |
