24 check-ins using file src/where.c version 56948ada

2016-03-05
15:35
Remove the unused journal.c source file (its function have been subsumed into memjournal.c). Refactor some of the names in memjournal.c. No functional changes. (check-in: 5f2a262d user: drh tags: trunk)
15:03
Work around (incorrect) ASAN warnings in memjournal.c. (check-in: 4de09777 user: drh tags: trunk)
14:19
Fix an integer size mismatch problem in test_bestindex.c (check-in: 2e35eb6b user: drh tags: trunk)
14:00
Fix an incorrect #ifdef on sqlite3LogEstToInt(). (check-in: dca7b233 user: drh tags: trunk)
2016-03-04
21:18
Fix an assert() in sqlite3VarintLen(), even though it is impossible to hit in SQLite due to the way sqlite3VarintLen() is used. (check-in: 251424c5 user: drh tags: trunk)
16:42
Merge recent enhancements from trunk. Default page size is 4096. Writes to statement journals are avoided. (check-in: 456df336 user: drh tags: sessions)
14:57
Merge recent enhancements from trunk, and especially the changes that reduce the heap-memory footprint of schemas, and defer opening and writing to statement journals. (check-in: 2f0c195c user: drh tags: apple-osx)
14:43
Defer opening and writing statement journals until the size reaches a threshold (currently 64KiB). (check-in: cb9302cc user: drh tags: trunk)
14:23
Update test cases to taken deferred statement-journal opening into account. (Closed-Leaf check-in: 5b2fe521 user: drh tags: memjournal-exp)
13:08
Merge changes from trunk. (check-in: a87305df user: drh tags: memjournal-exp)
04:01
Change the default cache_size to -2000 (which means 2000*1024 bytes independent of page_size). (check-in: 2682e8e4 user: drh tags: trunk)
03:43
Change the default page size for new database files to 4096 (from 1024). Except, when building the testfixture, preserve the legacy page size. Also fix a comment on SQLITE_MAX_ATTACHED. (check-in: 2e8a9ca9 user: drh tags: trunk)
03:20
Detect the presence of pread()/pwrite() system calls on unix systems and use them if available. (check-in: 82cbf5ad user: drh tags: trunk)
03:14
Further fixes to the pread()/pwrite() enabling logic. (Closed-Leaf check-in: 38fb54e7 user: drh tags: pread)
03:02
Fix the build for cases when pread()/pwrite() are not available. (check-in: 7d67d876 user: drh tags: pread)
02:59
Add the test_bestindex.c file to Makefile.in and Makefile.msc so that "make test" will work again. (check-in: 6ec6b6a9 user: drh tags: trunk)
02:38
Update the configure script to detect pread/pwrite and update os_unix.c to use those routines if they are available. (check-in: 2cffb9e5 user: drh tags: pread)
00:13
Get in-memory subjournals working for builds without SQLITE_ENABLE_ATOMIC_WRITE. (check-in: b5378dce user: drh tags: memjournal-exp)
2016-03-03
21:29
Merge the latest updates from trunk. (check-in: 55c00f71 user: drh tags: memjournal-exp)
21:22
Reduce the amount of heap memory required to store many schemas by storing the column datatype appended to the column name (with a \000 separator), rather than in separate memory allocation. (check-in: 16fbf2e1 user: drh tags: trunk)
20:42
Allow the left-hand side of IN operators on virtual tables to have the aConstraintUsage[].omit flag clear. (check-in: 3eb74342 user: drh tags: trunk)
2016-03-02
17:57
Add new test script bestindex1.test to the utf16 permutation. (Closed-Leaf check-in: 5893e972 user: dan tags: vtab-IN-opt)
16:13
Add an extra test for the change on this branch. (check-in: d2d28251 user: dan tags: vtab-IN-opt)
03:28
Allow the left-hand side of IN operators on virtual tables to have the aConstraintUsage[].omit flag clear. (check-in: 1622623c user: drh tags: vtab-IN-opt)
