11:43 | Cut over the next generation query planner. Increase the version number to 3.8.0. (check-in: 0fe31f60 user: drh tags: trunk) | |
00:34 | Fix an uninitialized variable detected by valgrind. Unclear whether or not this should apply to trunk. (Closed-Leaf check-in: 19ab4811 user: drh tags: nextgen-query-plan-exp) | |
2013-06-21
| ||
18:32 | Merge updates from trunk. (check-in: fa2a91e6 user: mistachkin tags: toTypeFuncs) | |
18:29 | Merge the fts4-notindexed branch with the trunk. (check-in: 361084e1 user: dan tags: trunk) | |
17:30 | Add the "notindexed" option to fts4. (check-in: 8ff2b8f5 user: dan tags: fts4-notindexed) | |
2013-06-20
| ||
18:53 | VSIX tooling changes to support Visual Studio 2013. (check-in: c5954c58 user: mistachkin tags: vsix2013) | |
17:32 | Add a NEVER() macro and an explanation comment around an unreachable branch in the STAT3 logic. (check-in: 604c3c5d user: drh tags: nextgen-query-plan-exp) | |
14:17 | Pull in the posix_fallocate() change from trunk. (check-in: d94db3fd user: drh tags: nextgen-query-plan-exp) | |
14:07 | Disable posix_fallocate() for all systems, all the time, unless the HAVE_POSIX_FALLOCATE compile-time macro is supplied. (check-in: b6744622 user: drh tags: trunk) | |
2013-06-19
| ||
14:49 | Only default HAVE_POSIX_FALLOCATE on for linux, and then only if it is not previously defined. (check-in: 2b2ade92 user: drh tags: trunk) | |
