Add compile time switch SQLITE_ENABLE_ICU_COLLATIONS. For enabling ICU collations without also enabling the tokenizer, the LIKE operator, the REGEXP operator, or the unicode aware upper()/lower() scalar functions. (check-in: a079f914 user: dan tags: trunk)
14:07
Make sure the bComplex variable in sqlite3DeleteFrom() is initialized when compiling with -DSQLITE_OMIT_TRIGGER. (check-in: e526d0c4 user: drh tags: trunk)
2017-12-07
22:10
When doing a table scan using an index, do not error out if collating functions used by that index are unavailable, since they will not be used. (check-in: bbd69fa6 user: drh tags: trunk)

21:01
Improved fix for ticket [da78413751863] that does not require disabling the query flattener as was done in [005d5b870625]. This also makes the code generator for vector IN operators a little easier to understand. (check-in: 723f1be3 user: drh tags: trunk)

2017-11-16
20:48
In the LSM extension, ensure that empty space on pages is zeroed before they are written to disk. This helps with compressed databases, and stops valgrind complaining about uninitialized bytes and write(). (check-in: 5ffec5db user: dan tags: trunk)

2017-11-13
05:51
Remove some branches in walTryBeginRead() that were added by check-in [ce5d13c2de] but became unreachable with the addition of logic in check-in [18b26843] that enabled read-only clients to parse the WAL file into a heap-memory WAL-index, thus guaranteeing that the WAL-index header is always available. (check-in: 9c6b38b9 user: drh tags: readonly-wal-recovery)
2017-11-11
20:11
In wal.c: improved comments, new assert() and testcase() macros, and replace some magic numbers with appropriate symbolic constants. (check-in: 13ec8a77 user: drh tags: readonly-wal-recovery)

15:43
On unix, if the *-shm file cannot be opened for read/write access, open it read-only and proceed as if the readonly_shm=1 URI option were specified. (check-in: ba718754 user: dan tags: readonly-wal-recovery)
09:08
