Add testcase() macros to the CHECK constraint avoidance logic. Avoid creating an unused VDBE label during CHECK constraint code generation. (check-in: 970881befd user: drh tags: trunk)
18:24
Fix to previous check-in: Make sure CHECK constraints involving the ROWID are not ignored when the ROWID changes. (check-in: 7782cb1dd5 user: drh tags: trunk)

22:39
Add the new "snapshot-tarball" target to the unix makefiles, for building a tarball similar to "amalgamation-tarball" but named by the SHA1 hash of the current check-out rather than by the version number. (check-in: 4f360b2ae7 user: drh tags: trunk)
22:00

20:31
In the shell, use the appropriate string constant instead of a literal new-line. (check-in: 61951b153d user: mistachkin tags: trunk)
20:11
Enhance the command-line shell to be in auto-explain mode by default. It is no longer necessary to use the ".explain" command to put the shell into a mode where the EXPLAIN output is formatted nicely. That now happens automatically. (check-in: 751915cb7e user: drh tags: trunk)
20:04
Improved auto-detection of EXPLAIN output in the shell. (Closed-Leaf check-in: 6c6d7a6e89 user: drh tags: auto-explain)
18:39
Add auto-explain mode to the command-line shell. Default on. Auto-explain tries to automatically detect EXPLAIN queries and format them appropriately. (check-in: 1d62aa6b31 user: drh tags: auto-explain)
18:28
Fix MSVC makefile options that enable control-flow guard. (check-in: 51b6823f4c user: mistachkin tags: trunk)

16:09
Code simplification: ALTER TABLE ADD COLUMN always upgrades the file_format to 4 if is not there already. No need to upgrade to only 2 or 3 since format 4 has now been supported for over 10 years. (check-in: e1d8ec8554 user: drh tags: trunk)
15:50
Merge recent fixes and enhancements from trunk. (check-in: f073401792 user: drh tags: apple-osx)
15:44

Merge latest trunk changes with this branch. (check-in: 1a4182eedd user: dan tags: schemalint)
02:12
Make sure every co-routines has its own set of temporary registers and does not share temporaries, since a co-routine might expect the content of a temporary register to be preserved across an OP_Yield. Proposed fix for ticket [d06a25c84454a]. (check-in: ca72be8618 user: drh tags: trunk)
2016-02-08

Fix a compiler warning when compiling without SQLITE_ENABLE_FTS3_TOKENIZER. (check-in: 6926f28cd5 user: drh tags: trunk)
19:40
Disable the two-argument form of the fts3_tokenizer() SQL function unless the library is built with -DSQLITE_ENABLE_FTS3_TOKENIZER. (check-in: e0eb217aca user: dan tags: trunk)
19:36
Changes to help the tokenizer run about 33% faster. (check-in: a050e6f096 user: drh tags: trunk)
19:15
Add code to get the tokenizer character-class logic working for EBCDIC. (Closed-Leaf check-in: 04f7da77c1 user: drh tags: tokenizer-char-class)
03:23
Faster keywordCode() implementation by taking advantage of the fact that the input is always pure ASCII alphabetic and underscore and that the keyword table is always upper-case. (check-in: ff406b9701 user: drh tags: tokenizer-char-class)
02:30
Demonstrate a much faster sqlite3GetToken() routine by using a lookup table to map initial token characters into a character class. This check-in does not work for EBCDIC. More optimization needed. (check-in: 9115baa191 user: drh tags: tokenizer-char-class)
2016-02-07
20:39
Fix harmless compiler warning in 'srcck1' tool and add it to the clean targets. (check-in: 852a529a8b user: mistachkin tags: trunk)

Add the sourcetest target to Makefile.msc. (check-in: ab269e7205 user: drh tags: trunk)
2016-02-06
22:32
Add a utility program that looks for assert(), NEVER(), ALWAYS(), and testcase() macros that have side-effects, and reports errors when they are found. Also fix a bug that this utility detected as it was being tested. (check-in: b0b4624fc5 user: drh tags: trunk)
19:48
Make sure variable declarations occur at the beginning of blocks, even with SQLITE_DEBUG enabled. (check-in: 2f7778e64d user: drh tags: trunk)
14:14
Fix an assert() to have a test instead of a side effect (check-in: a2952231ac user: pdr tags: trunk)
2016-02-05
21:09
Add tests for and remove unreachable branches from fts5 in order to restore test coverage. (check-in: 22589018ac user: dan tags: trunk)
19:40
More work on Windows 10 SDK integration. (Closed-Leaf check-in: ebace2c99b user: mistachkin tags: win10sdk)
19:18
Further streamlining of fts5 prefix query code. (check-in: ca91bd8ac7 user: dan tags: trunk)
17:49
Make sure the "bak.db" database file does not actually exist before starting the "quota.test" testing. (check-in: 1cac6c45ee user: drh tags: trunk)
16:46
From test scripts, remove stray "breakpoint" commands and blank lines at the ends of files. (check-in: a6b3527323 user: drh tags: trunk)

14:15
Merge enhancements from trunk. (check-in: a533608cb0 user: drh tags: sessions)
14:11
Improvements to the way out-of-memory conditions are handled, resulting in an almost 1% performance gain in the commmon case where OOM errors do not occur. (check-in: b082538da7 user: drh tags: trunk)
13:38
Add the slightly faster sqlite3DbMallocRawNN(db,n) routine for the majority cases where db is guaranteed to be not NULL. (Closed-Leaf check-in: 0a802e96ab user: drh tags: oom-handling)
04:55
Improve ERRORLEVEL handling in the MSVC batch build tool sub-routine 'fn_UnsetVariable'. (check-in: fe123ab4f1 user: mistachkin tags: trunk)
04:50
OOM failures on sqlite3_errmsg16() in an app-defined function are no longer benign. (check-in: 9efb223f4c user: drh tags: oom-handling)
04:39
Another small tweak to the MSVC batch build tool. (check-in: 76718bbce7 user: mistachkin tags: trunk)
02:50

2016-02-04
19:50
Temporarily back out the 0.5% performance improvement from check-in [632071bac5ff32]. Need a more elaborate solution that works with reentrant virtual tables and SQL functions. (check-in: 42736fb0ad user: drh tags: trunk)
19:45
Further improve performance of unindexed fts5 prefix queries. (check-in: c9c6457d8e user: dan tags: trunk)
17:31
Avoid running some particularly time-consuming tests as part of veryquick.test. (check-in: f465944b75 user: dan tags: trunk)
11:48
Remove unnecessary sets of db->mallocFailed. (check-in: b787165b25 user: drh tags: trunk)
11:15
Use sqlite3_malloc64() instead of sqlite3_malloc() in the spellfix extension. (check-in: 634d008c34 user: drh tags: trunk)
10:28
Escape control characters in JSON. Fix for ticket [ad2559db380abf8]. (check-in: 4f1b5229a3 user: drh tags: trunk)
09:48
Refinements to synchronous logic: (1) Use PAGER_SYNCHRONOUS_FULL rather than the corresponding magic number. (2) Honor SQLITE_NO_SYNC on xDelete calls with sync (3) Count xDelete syncs during testing (4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal unlink are off by default. (check-in: e3157cb5ad user: drh tags: trunk)
02:34
Add and use the sqlite3VdbeZeroRegister() interface for coding the common operation of writing zero into a register. (Leaf check-in: 1c8d300189 user: drh tags: zero-register)
2016-02-03
22:14
In the VDBE loop, only check for OOM errors at jumps rather than after every opcode, for about a 0.5% performance increase. (check-in: 632071bac5 user: drh tags: trunk)
