In kvtest.c, use stat() instead of fseek()/ftell() to determine the size of a BLOB to be read directly from disk. This makes the pile-of-files database more competative against SQLite. check-in: a7dca29f user: drh tags: trunk
16:58

Enable ossfuzz.c to build even if SQLITE_OMIT_PROGRESS_CALLBACK is defined. check-in: a37c00dc user: drh tags: trunk
01:41
Remove an incorrect ALWAYS() macro from balance_nonroot(), which could result in corrupt databases if it were optimized out. This ALWAYS was added only two weeks ago (check-in [f9f2e23bbd68a]) and has never appeared in an official release. check-in: e447b23c user: drh tags: trunk
00:18
Add the built-in affinity() SQL function. check-in: 57e40e1c user: drh tags: affinity-sql-func
00:15

2016-12-24
21:32
Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. check-in: def29333 user: drh tags: trunk
19:37
The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. check-in: 2f481b85 user: drh tags: trunk
18:18

18:04
In the command-line shell, improve the formatting to the ".databases" command and on the ".tables" command, only show the schema prefix for databases past the first ("main") database. check-in: c0d5626e user: drh tags: trunk
2016-12-23
16:05
Fill in missing opcode documentation entries for OP_SorterNext and OP_SorterSort. check-in: 2940661b user: drh tags: trunk

2016-12-21
21:26
Change the default lookaside configuration from 500 slots of 128 bytes each to 125 slots of 512 bytes each. This uses the same amount of memory (64,000 bytes) but seems to perform much better in test applications. check-in: 52a12e47 user: drh tags: trunk
19:45
Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. check-in: f7ab01f2 user: drh tags: trunk
2016-12-18
17:42
Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. check-in: 165c0446 user: drh tags: trunk
2016-12-17
21:07
Refinements to the new dbfuzz test program. check-in: 50325abe user: drh tags: trunk

08:18
Fix a problem in the shell tools readfile() command causing blobs to be truncated at the first embedded 0x00 byte in release builds, or an assert() to fail in a debug build. check-in: 8dedd6ad user: dan tags: trunk
2016-12-16
21:29
Merge recent enhancements from trunk, and especially the pragma-as-vtab change. check-in: 4b1e7804 user: drh tags: apple-osx
