2017-02-21
| ||
17:52 | Fix an FTS5 problem that could cause a crash when certain queries were interrupted using sqlite3_interrupt(). (check-in: e400909f user: dan tags: trunk) | |
15:27 | Very small enhancement to dispatch speed for SQL functions. (check-in: 3c3228ed 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: 7a62fc6a 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: 9626b41e user: drh tags: vdbe_cycle_limit) | |
2017-02-20
| ||
23:32 | Correct a harmless typo in the previous check-in. (check-in: 1589db01 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: 96b6a98e user: mistachkin tags: trunk) | |
14:30 | Small grammar simplification. (check-in: 0d8a868a user: drh tags: trunk) | |
13:11 | Merge fixes from trunk. (check-in: ff213f2e user: drh tags: auto-analyze) | |
2017-02-18
| ||
22:52 | Updated comments. No code changes. (check-in: e842ad39 user: drh tags: auto-analyze) | |
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: d386015f 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: 49181427 user: drh tags: trunk) | |
02:42 | Fix errors in the table resize detection. (check-in: 4229caec 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: 882599a4 user: drh tags: auto-analyze) | |
2017-02-17
| ||
23:52 | Fix the #endif location for an #ifndef SQLITE_UNTESTABLE macro in the command-line shell. (check-in: 8cc9d74c user: drh tags: trunk) | |
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: bfbdd074 user: drh tags: auto-analyze) | |
16:26 | Add the "PRAGMA analyze_as_needed" command. (check-in: e93db237 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: fb2b8ae8 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: 85026c8e user: drh tags: auto-analyze) | |
02:07 | Merge fixes from trunk. (Leaf check-in: 662e8ccf 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: 218b2bbb 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: 8a03be1d user: drh tags: trunk) | |
2017-02-16
| ||
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: aa0703e5 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: 9fc5cd50 user: drh tags: trunk) | |
17:18 | Change two MallocZero() calls into MallocRaw() to avoid unnecessary memset(). (check-in: ff5e733c user: drh tags: trunk) | |
16:26 | Fix a comment on a field of the ExprList object. No changes to code. (check-in: bb8e2642 user: drh tags: trunk) | |
15:57 | Increase Table.tabFlags from 8 to 32 bits. (check-in: 7e14044c user: drh tags: trunk) | |
15:06 | Remove two redundant initializations from the virtual table logic. (check-in: 6bd82b95 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: 6affb1c8 user: drh tags: trunk) | |
14:02 | Merge recent enhancements from trunk. (check-in: 325ccfa9 user: drh tags: est_count_pragma) | |
2017-02-15
| ||
22:36 | Query planner optimization to detect empty tables in a join early and bail out without doing excess work. (check-in: 58797e9b user: drh tags: trunk) | |
18:30 | Minor enhancement to mutex tracing on Win32. (check-in: 830b9235 user: mistachkin tags: trunk) | |
17:47 | simple test cases for carray_asc. (Leaf check-in: 1d4759c1 user: drh tags: carray_asc) | |
16:11 | Add the companion "carray_asc" table-valued function to the carray extension. (check-in: a2b4f60b user: drh tags: carray_asc) | |
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: 810d2932 user: drh tags: trunk) | |
04:16 | Further reforms to Tcl_*Alloc() usage. (check-in: ee1e6896 user: mistachkin tags: trunk) | |
01:39 | In the blob test code, avoid crashing on low-memory systems by using Tcl_AttemptAlloc(). (check-in: 1d267757 user: mistachkin tags: trunk) | |
01:02 | Make SQLITE_GET_MUTEX_TIME a proper noop on non-Win32/non-POSIX. (Leaf check-in: 4ca2b2f8 user: mistachkin tags: mutexDbg2) | |
00:52 | Another compilation fix for POSIX. (check-in: 82ef47ea user: mistachkin tags: mutexDbg2) | |
00:45 | Make fine time granularity work on POSIX. (check-in: 79057716 user: mistachkin tags: mutexDbg2) | |
00:02 | Compilation fix for POSIX. (check-in: 9964ad24 user: mistachkin tags: mutexDbg2) | |
2017-02-14
| ||
23:58 | Experimental enhancements to mutex debugging. (check-in: 80481754 user: mistachkin tags: mutexDbg2) | |
21:47 | Clarification of the help text for the command-line shell. (check-in: ca4f1e49 user: drh tags: trunk) | |
20:00 | Enable the SQLITE_ENABLE_NULL_TRIM option for WITHOUT ROWID tables. (check-in: 54836270 user: drh tags: trunk) | |
16:30 | More realistic lengths of string values in speedtest1 with --testset orm. (check-in: e4731fd6 user: drh tags: trunk) | |
15:58 | Fix a testcase number on the ORM testset of speedtest1. (check-in: 58b2f911 user: drh tags: trunk) | |
15:57 | Add the new "--testset orm" to the speedtest1 utility. (check-in: 1836adc1 user: drh tags: trunk) | |
2017-02-13
| ||
13:35 | Change all legacy instances of "#if SQLITE_DEBUG" to "#ifdef SQLITE_DEBUG" for consistency. (check-in: 670f10b2 user: drh tags: trunk) | |
