Add a couple of missing methods to test_osinst.c.. (check-in: 5c9e9c06 user: dan tags: trunk)
00:55
Add several EXPENSIVE_ASSERT code blocks to validate the wal-index hash table. Fix the bugs that these code blocks fine. Rename walClearHash() to walCleanupHash() and simplify its interface. (check-in: 7aade899 user: drh tags: trunk)
2010-05-21
19:15
Fix another bug in walClearHash(). (check-in: 40f80ffe user: dan tags: trunk)
18:24
Comment out the SQLITE_FCNTL_SIZE_HINT from os_unix.c since it does not seem to provide any performance gain there. (check-in: 7d01309d user: drh tags: trunk)
16:23
Correct an off-by-one bug in the previous commit. (check-in: 75a1130d user: dan tags: trunk)
15:31
Remove entries from wal-index hash tables when a rollback or savepoint rollback occurs. (check-in: 36795c2b user: dan tags: trunk)
13:16
Fix the wal-index header read routine so that it correctly detects a zero header as being malformed and in need of a wal-index rebuild. (check-in: 1a4eb3a3 user: drh tags: trunk)
2010-05-20
23:51
Add a new xShmBarrier method to the VFS - a shared-memory fence operation. Implement the same in both unix and win32. Use it to make the WAL subsystem more robust. (check-in: 1bd011c9 user: drh tags: trunk)
21:21
Make use of the extra information in the WAL header and frame header to enhance robustness. (check-in: 9580ecb7 user: drh tags: trunk)
