59 check-ins using file src/vdbe.c version 75da79cd

2012-08-28
14:45
Fix a case where SQLite was failing to detect a syntax error in queries like "SELECT ... FROM (<select-1> UNION ALL <select-2>)" when <select-1> and <select-2> return different numbers of result columns. (check-in: 200a8135 user: dan tags: trunk)
04:20
Issue a log message if the temporary directory has not been set when running on WinRT. (check-in: 9ee39102 user: mistachkin tags: trunk)
01:44
Enable the use of a simpler command line when cross-compiling in the MSVC build environment. (check-in: 8ade136a user: mistachkin tags: trunk)
00:17
Formatting changes to the C code example in the documentation for sqlite3_temp_directory(). No changes to code. (check-in: 5b4b3978 user: drh tags: trunk)
00:09
Update API docs to include notes about the WinRT temporary directory. No changes to code. (check-in: eaeeb069 user: mistachkin tags: trunk)
2012-08-27
21:19
Add to #undef statements to the command-line shell, go make sure that the macros definitions that follow do not collide with system definitions. (check-in: 24420d6d user: drh tags: trunk)
14:39
Fix an incorrect assert in the virtual table logic - it could fire following an I/O error after sqlite3_close_v2() was added. (check-in: 4ccc18e9 user: drh tags: trunk)
2012-08-25
10:01
Fix all known instances of 'repeated the' style typos in comments. No changes to code. (check-in: 9b19b847 user: mistachkin tags: trunk)
02:11

2012-08-24
23:56
When the same index is used for all OR-terms in a WHERE clause, then try to use that index as a covering index. (check-in: 62678be3 user: drh tags: trunk)
23:24
Move field WhereLevel.pCovidx inside the union to WhereLevel.u.pCovidx. (Closed-Leaf check-in: b722143d user: drh tags: multi-or-covering-index)
21:54
Remove a NEVER() that is in fact reachable on an OOM. This probably has nothing to do with the multi-or-covering-index change but just happened to be found while testing that change. (check-in: 5499af53 user: drh tags: multi-or-covering-index)
19:58
Another test for whereD.test. (check-in: 29d58617 user: dan tags: multi-or-covering-index)

17:52
More test cases for OR-optimization covering indices. (check-in: e5c3190c user: drh tags: multi-or-covering-index)
15:29
Additional test cases for OR-optimization with covering indices, including one test case that currently fails. (check-in: d8b7ab37 user: drh tags: multi-or-covering-index)
10:52
Experimental change to support the covering index optimization for queries with OR terms in the WHERE clause that search a single index more than once. (check-in: 1dc8c7c7 user: dan tags: multi-or-covering-index)
01:07
Merge the nested aggregate query enhancements into trunk. (check-in: d4cd6017 user: drh tags: trunk)

00:18
Add assert to check that the memory block for the previous directory value was allocated via sqlite3_malloc or related function. (Closed-Leaf check-in: 1246f15b user: mistachkin tags: win32SetDir)
2012-08-21
23:33
Added sqlite3_win32_set_directory API to assist in portability to WinRT. (check-in: 600de08d user: mistachkin tags: win32SetDir)
17:46
Merge in all the latest trunk changes. (check-in: 45cdc32f user: drh tags: threads-sort-ex1)
17:44
Update the spellfix virtual table so that all OOM errors are reported out to the application. (check-in: 573770f5 user: drh tags: trunk)
17:36
Cherry-pick [555fc07]: Changes to the thread routines to disable them when threading is turned off using sqlite3_config(). Also merge all recent trunk changes. (check-in: c92b0fe1 user: drh tags: threads)
13:08
Update the spellfix virtual table so that all OOM errors are reported out to the application. ERROR: A single edit was missed in spellfix1 which means that this particular check-in won't build "make test". (Closed-Leaf check-in: c2cf4985 user: drh tags: mistake)
2012-08-20
17:24
Add the SQLITE_DISABLE_FTS4_DEFERRED compile time option. (check-in: e799222f user: dan tags: trunk)

Remove tab characters from source code files. Replace them with spaces. (check-in: 7edd10a9 user: drh tags: trunk)
15:46
Add a command-line program to tool/ that will check source code files for the presence of tabs, carriage-returns, whitespace at the ends of lines, and blank lines at the ends of files. (check-in: 656a9c8b user: drh tags: trunk)
12:36
Changes to the thread routines to disable them when threading is turned off using sqlite3_config(). (check-in: 555fc07e user: drh tags: threads-sort-ex1)
2012-08-17
13:44
Clarify that the number-of-bytes parameter to sqlite3_bind_blob() must be non-negative. (check-in: b1b01c4c user: drh tags: trunk)
12:13
Fix MSVC compiler warning in the spellfix module. Also, add an assert. (check-in: e66cf040 user: mistachkin tags: trunk)
11:47
Skip defining some WAL specific things in the Win32 VFS code when compiling without WAL support. Also, fix an example command line in the MSVC makefile. (check-in: 61b1ae12 user: mistachkin tags: trunk)
2012-08-16
20:05
Attempt to use two cores to do sorting. Unfortunately, instead of making sorts go faster as was hoped, this changes slows sorting down by about 10%. (Later:) The previous measurement was compiled using -pg. When compiled using -Os, this new code is roughly 10% faster than the original. (check-in: 11dd05e5 user: drh tags: threads-sort-ex1)
11:24
Update the threads branch to include all the latest trunk changes. (check-in: f4125771 user: drh tags: threads)

Changes to the spellfix test script to make the results deterministic. (check-in: 31c07db2 user: drh tags: trunk)
16:06
Change autoconf so that the --with-tcl=DIR option will override the TCL configuration that is found using tclsh. (check-in: 772d0de3 user: drh tags: trunk)
2012-08-14
19:04
Silence three harmless compiler warnings in vdbesort.c. (check-in: a5431c86 user: drh tags: trunk)
18:43
Add an assert() to the btree rebalancer in order to silence a clang/scan-build warning. (check-in: 6730579c user: drh tags: trunk)
17:29
Update the spellfix virtual table to the latest development code. (check-in: 6954fef0 user: drh tags: trunk)
01:45
Refer to the file mapping Win32 API functions only when absolutely necessary. (check-in: 1de2237d user: mistachkin tags: trunk)
2012-08-13
22:05
Refer to the WaitForSingleObjectEx and SetFilePointerEx Win32 functions only for platforms where they are going to be used. (check-in: 9888ce92 user: mistachkin tags: trunk)
2012-08-08
14:04
When populating an index b-tree as part of a CREATE INDEX or REINDEX statement, distribute cells between up to three siblings in balance_nonroot() instead of four. This produces identical database files, but is slightly faster. (check-in: b0d31e77 user: dan tags: trunk)
11:55
When building a b-tree as part of a CREATE INDEX or REINDEX statement, attempt to pack keys into pages as tightly as possible. (check-in: efea62b9 user: dan tags: trunk)
10:14
Change to securedel2.test so that it works even if SQLITE_DEFAULT_AUTOVACUUM=1 is defined. (check-in: 1e6f5ea4 user: dan tags: trunk)
2012-08-07
22:53
Simplifications to the sorter to support full-coverage testing. (check-in: de804f4c user: drh tags: trunk)
17:41
Add extra tests for secure-delete mode. (check-in: e380cd3c user: dan tags: trunk)
15:19
Fix a bug in hash.c introduced by [305b66672653]. (check-in: 17cb5e95 user: dan tags: trunk)
14:18
Do not run test script spellfix.test if SQLITE_OMIT_VIRTUAL_TABLE is defined. Fix walro.test so that it works if DEFAULT_AUTOVACUUM is defined. (check-in: 26428b45 user: dan tags: trunk)
13:55
Fix a bug in walthread.test causing intermittent failures. (check-in: a192a718 user: dan tags: trunk)
2012-08-06
22:29
Modify VSIX package generation tool to put the PDB files in the Debug directory. (check-in: 9d072083 user: mistachkin tags: trunk)
19:28
Merge the sorter-coalesce-writes branch into the trunk. This improves CREATE INDEX performance on some platforms. (check-in: e1e9cb08 user: dan tags: trunk)
19:12
Fix a crash that could follow an OOM condition. (Closed-Leaf check-in: 2e5741f7 user: dan tags: sorter-coalesce-writes)
18:50
When reusing pages as part of creating a new index, allocate the leaves from each free-list trunk page in ascending order, instead of trying to maximize localization for each individual allocation. This increases the chance that pages will be written to disk in ascending order by a large CREATE INDEX statement, improving overall performance. (check-in: d045f8b2 user: dan tags: sorter-coalesce-writes)
