Changes In Branch oom-handling Excluding Merge-Ins
This is equivalent to a diff from 42736fb0ad to 0a802e96ab
2016-02-05
| ||
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) | |
04:50 | 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) | |
01:55 | Improvements to the way that OOM errors are processed. (check-in: c3ef03478a user: drh tags: oom-handling) | |
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) | |
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) | |
