| 23:54 | For in-memory databases, it does not matter if pcache entries are marked "clean" or "writable". Closed-Leaf check-in: ad601c79 user: drh tags: pager-dev | |
| 20:03 | Remove a redundant condition from pcache.c. Add an OPTIMIZATION-IF-TRUE comment to another condition that requires it. check-in: 3bfd2621 user: dan tags: trunk | |
| 18:20 | Remove a redundant condition from pcache.c. Add an OPTIMIZATION-IF-TRUE comment to another condition that requires it. Closed-Leaf check-in: 4533ed35 user: dan tags: mistake | |
| 15:41 | Remove some a small amount of redundant code related to PCache.pSynced from pcache.c. check-in: 9cc8cad7 user: dan tags: trunk | |
| 12:47 | Do not reset the page cache when a rollback journal truncate fails, as doing so can cause loss of information for an in-memory TEMP file. check-in: 345ce1c9 user: drh tags: trunk | |
| 11:04 | Always truncate, rather than persist, the rollback journal of a TEMP database. check-in: 42fb6f1e user: drh tags: trunk | |

|
2016-05-09
| ||

| 18:47 | Corrections to comments on the whereScanInit() interface. check-in: ab7ab415 user: drh tags: trunk | |
| 16:49 | For DELETE operations, make sure that seeks on the main table are not deferred, since if they are and none of the indexes reference columns of the table, the seek might never occur until the OP_Delete opcode, which is too late. Fix for ticket [16c9801ceba49]. check-in: 93a2bace user: drh tags: trunk | |
| 16:30 | Fix an error in main.mk causing testfixture to use individual fts5 source code files instead of fts5.c. check-in: 933a1c81 user: dan tags: trunk | |
| 16:06 | In the WHERE generator, when building code for a DELETE operation, make sure that seeks to the main table are not deferred. This is a better fix for the [16c9801ceba49] bug than the previous. Closed-Leaf check-in: 150dd09e user: drh tags: ticket-16c9801ce | |
| 15:16 | Fix a bug in sqlite_analyzer causing it report (slightly) incorrect values for the number of entries in indexes or WITHOUT ROWID tables. check-in: dc37750d user: dan tags: trunk | |
| 11:31 | Do not scan indexes that have the integer primary key as their left-most column. This fixes the crash of ticket [16c9801ceba] but it seems like the wrong fix. More investigation needed. check-in: 50312273 user: drh tags: ticket-16c9801ce | |

| 23:59 | Additional error reporting. Open the source database read/write so that it can delete the WAL file when done. check-in: d2efd3c1 user: drh tags: scrub-backup | |
| 23:39 | Working when run against sqlite.fossil. check-in: b0bd9dd6 user: drh tags: scrub-backup | |
| 23:09 | Finished implementation compiles, but untested. check-in: aeb88bdf user: drh tags: scrub-backup | |
| 17:15 | Initial check-in of the "scrub.exe" utility program prototype. Not yet fully functional. In particular, no scrubbing is done. check-in: bdf2ec77 user: drh tags: scrub-backup | |

| 14:45 | Only disable the one-pass DELETE optimization if the WHERE clause contains a correlated subquery. Uncorrelated subqueries are allowed. This is a refinement of check-in [3f221f592a9a1] that is the fix for ticket [dc6ebeda9396087]. check-in: aae38969 user: drh tags: trunk | |
| 14:20 | Portability enhancements to the configure script on the amalgamation tarball. check-in: 7184c4b8 user: drh tags: trunk | |
| 11:28 | Disable the PagerDontWrite() optimization for temp tables. It can cause database corruption if a page passed to PagerDontWrite() is dirty at the start of a transaction that is subsequently rolled back. check-in: 6341ab2f user: dan tags: trunk | |
|
2016-05-03
| ||
| 19:40 | Minor style tweaks in the MSVC makefile. check-in: 1b43358f user: mistachkin tags: trunk | |
| 19:36 | Add the experimental SQLITE_FCNTL_WIN32_GET_HANDLE file control. Leaf check-in: b6ddabe1 user: mistachkin tags: win32GetHandle | |
| 14:57 | The session extension is disabled by default. To enable it using --enable-session on ./configure on unix and add SESSION=1 to the nmake on Windows. Or add -DSQLITE_ENABLE_SESSION and -DSQLITE_ENABLE_PREUPDATE_HOOK to build manually. check-in: bcaa650e user: drh tags: trunk | |
| 13:14 | Turn the session extension off by default. Enable using --enable-session on configure scripts, or using the SESSION=1 argument to nmake on Windows. Closed-Leaf check-in: e462cde2 user: drh tags: session-make | |

| 19:05 | Remove some randomness from test script temptable2.test. check-in: 5830cf72 user: dan tags: trunk | |
| 16:59 | Fix a test case in temptable2.test so that it works on systems that lack a coherient cache (ex: OpenBSD) and thus do not support the "PRAGMA mmap_size" command. check-in: 088cf838 user: drh tags: trunk | |
| 15:00 | Merge enhancements and bug fixes from trunk. check-in: f52765ee user: drh tags: apple-osx | |

| 18:10 | Remove an unnecessary branch from the OP_String8 opcode. check-in: 459a0b45 user: drh tags: trunk | |

| 14:15 | Use comments to mark several branches as optimizations. No changes to code. check-in: 33e62747 user: drh tags: trunk | |
| 09:53 | Ensure that quota.test deletes the directory named "test.db" that it creates. check-in: 045edd4b user: dan tags: permutations-fix | |
| 03:52 | Remove an unnecessary conditional from the sqlite3DecOrHexToI64() routine. check-in: fcf85bfe user: drh tags: trunk | |
| 00:32 | Change the sqlite3Atoi64() routine so that it returns failure if not all of the input characters are consumed, even if it consumed all characters up to the first 0x00. This has no impact on external APIs as far as I can tell. check-in: 46d4ffff user: drh tags: trunk | |
|
2016-04-27
| ||
| 18:54 | Modify the permutations.test script so as to set any permutation specific configuration values before running each individual test script. check-in: 2662d8fe user: dan tags: permutations-fix | |
| 15:24 | More simplification of the sqlite3AtoF() routine. Add special comments to indicate branches that are for optimization purposes only and that give the correct answer even if always or never taken. check-in: 0065fe97 user: drh tags: trunk | |
