6 check-ins using file src/os_unix.c version 559f9f18

2010-05-01
11:33
Fix a typo in the walmode.test test script introducted yesterday. (check-in: dcabc90c user: drh tags: wal)
11:19
Fix the sqlite3_mutex_alloc() interface to return NULL (not segfault) when operating in threadsafe mode. (This is a general-purpose bug fix which really ought to be ported to trunk.) (check-in: 64840a3c user: drh tags: wal)
08:30
Add test case demonstrating deadlock during recovery of very large log files. No fix yet. (check-in: 63ea318e user: dan tags: wal)
00:59
Do not allow journal_mode=WAL if the underlying VFS does not support xShmOpen. (check-in: d1fcccec user: drh tags: wal)

Merge in changes from the trunk. (check-in: 76bf0eee user: drh tags: wal)
17:47
Change the SHM VFS logic in os_unix.c so that it does not hold an exclusive lock n the mapped memory when also holding a CHECKPOINT lock. This improves concurrency between readers and checkpointers. (check-in: 8660cda6 user: drh tags: wal)
