13 check-ins using file src/sqlite.h.in version 29bda4be

2017-01-09
07:00
Merge the "changebatch" functionality into this branch. (check-in: 50fb1eb3 user: dan tags: begin-concurrent)
06:53
Disable the optimization from [8cb8516d] (omit TableLock instructions for non-sharable databases) on this branch. This branch uses the TableLock instructions to ensure that the db schema is not written from within a BEGIN CONCURRENT transaction. (check-in: c8ca3e0a user: dan tags: begin-concurrent)
06:33
Upgrade this branch to 3.16 plus the various fixes that appeared after its release. (check-in: d0e212d0 user: dan tags: begin-concurrent)
2017-01-07
14:47
Improvements to the iIdxNoSeek optimization of sqlite3GenerateRowDelete() so that it is automatically disabled for BEFORE triggers but works in all other cases. (check-in: 3178ec4c user: drh tags: trunk)
14:26
Critical fix to the previous check-in so that it works when there are BEFORE triggers that move the cursor before the OP_Delete has a chance to be applied. (check-in: db2c0960 user: drh tags: trunk)
03:26
Avoid an unnecessary btree seek while deleting an index entry due to a conflict on a REPLACE operation. (check-in: f0495c51 user: drh tags: trunk)
00:56
Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. (check-in: d577dda0 user: drh tags: trunk)
00:42
This hack illustrates how to use the VDBE_PROFILE mechanism to show which bytecode operators are using resources other than time. In this case, the number of loops through the binary search code in sqlite3BtreeMovetoUnpacked() is measured, for the purpose of helping to identify unnecessary btree searches.

2017-01-06
16:32
Version 3.16.2 (Leaf check-in: a65a6289 user: drh tags: release, branch-3.16, version-3.16.2)
13:53
Clarify the documentation on sqlite3_column_count(). (check-in: 01b4cb26 user: dan tags: branch-3.16)
13:49
Ensure that "PRAGMA case_sensitive_like" and "PRAGMA shrink_memory" set the number of output columns to 0 (as they are statements that return no data). (check-in: 6696cd18 user: dan tags: trunk)
11:55
Improve handling of corrupt data in fts5. (check-in: 609ac1c7 user: dan tags: trunk)
01:09
Clarify the documentation on sqlite3_column_count(). (check-in: 9ea0badd user: drh tags: trunk)
