2015-04-21
20:13
Fix a problem in fts5fault1.test. (check-in: a21d60cb user: dan tags: fts5)

2015-04-15
18:49
Logically store updates as (insert+delete) within the FTS tree. This allows keys to be annihilated more quickly under some circumstances. (check-in: 50fae1f0 user: dan tags: fts5)
16:01
Fix a problem preventing doclist indexes from being loaded. (check-in: b29109a0 user: dan tags: fts5)

2015-04-11
18:25
Have fts5 integrity check verify that prefix indexes contain the same values as returned by prefix queries on the main terms index. (check-in: bdb8e82a user: dan tags: fts5)
16:23
Improve fts5 integrity-check so that it checks that DESC queries return the same as ASC. Change the poslist format slightly to make room for a delete-flag. (check-in: 49c1e745 user: dan tags: fts5)
2015-04-07
21:17
Correct typo in new test numbering. (check-in: d176c9fa user: mistachkin tags: expShell)

19:55
Track total memory usage using a 64-bit integer on 64-bit systems. Add the sqlite3_status64() interface. Make the sqlite3_status() and sqlite3_status64() interfaces atomic using mutexes and verify correct mutex operation using assert() statements. (check-in: 6fc4e79a user: drh tags: trunk)
19:16
Fix a non-C89 variable declaration that causes problems for MSVC. (Closed-Leaf check-in: 3de085ea user: drh tags: status64)
19:03
Fix datetype size asserts in btree.c. (check-in: ff4812d0 user: drh tags: trunk)
18:52
Add the SQLITE_PTRSIZE macro. Use it to help sqlite3_status() run faster on 32-bit systems. (check-in: c742bd60 user: drh tags: status64)
17:25
Add the sqlite3_status64() interface. Make the new interface and the legacy sqlite3_status() both atomic and threadsafe. Check threadsafety using assert()s. (check-in: 1ce8e8fa user: drh tags: status64)
14:39

Increase the debugging level for the debug configuration in the MSVC batch build tool. (check-in: 041484ff user: mistachkin tags: trunk)

16:40
Change walblock.test to block an external process for 10 seconds, not 5. 5 seconds is not long enough to tell the difference between a blocking lock and a series of retries. (check-in: 717335fc user: dan tags: trunk)
16:36
Fix the blocking WAL lock so that it works and so that it compiles on a Mac. (check-in: 67d69d21 user: drh tags: trunk)

12:22
Avoid an integer overflow in fts3 causing gcc 4.7.1 with -O2 to behave counter-intuitively (perhaps because the behaviour is undefined). Add an "ifcapable trace" to a test in shell4.test. (check-in: e3e23464 user: dan tags: trunk)
12:22
Remove an unreachable branch from the OP_VCreate opcode. (check-in: 5fca41a3 user: drh tags: trunk)

Where possible insert the set of new keys for each index in sorted order within "INSERT INTO ... SELECT" statements. (check-in: 0a7f2051 user: dan tags: insert-select-opt)
16:54
Provide the BTREE_SEEK_EQ hint to the b-tree layer. (check-in: 3c367004 user: drh tags: trunk)

19:59
Fix a crash that can occur following an OOM condition within a CREATE VIRTUAL TABLE statement on a utf-16 database. (Closed-Leaf check-in: 9453e7da user: dan tags: malformed-vtab-name)

16:25
Fix an FTS3/4 problem with handling empty tokenizer declarations (e.g. "CREATE VIRTUAL TABLE t(tokenize=);"). (check-in: 26d2def8 user: dan tags: trunk)
15:52
Silently ignore any attempt to add a prefix index for prefixes zero bytes in size to an fts3/4 table. Or any prefix index size so large that it overflows a 32-bit signed integer. (check-in: ad4b19d2 user: dan tags: trunk)
15:04

Fix typo of test prefix in the new WHERE test file. (check-in: 34779c52 user: mistachkin tags: trunk)
17:48
When the WHERE clause contains two OR-connected terms with identical operands but different operators, try to combine them into a single term. Example: (X=A OR X>A) becomes (X>=A). (check-in: 8bdda827 user: drh tags: trunk)
17:07
Modify the fts3query.test script so that it works even when testfixture is built using a version of TCL that is unable to sort the integer -9223372036854775808 (check-in: f61fd24b user: drh tags: trunk)
