Merge changes from the 3.11.0 release candidate. (check-in: d198a6db user: drh tags: apple-osx)
2016-02-09
15:50
Merge recent fixes and enhancements from trunk. (check-in: f0734017 user: drh tags: apple-osx)
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: ca72be86 user: drh tags: trunk)
2016-02-05
14:29
Merge OOM handling optimizations and PRAGMA synchronous=EXTRA as well as other enhancements from trunk. (check-in: 201fcbee user: drh tags: apple-osx)
