17 check-ins using file src/os_win.c version 1e44ee84

2010-05-25
10:50
If a writer exits unexpectedly in the middle of a transaction, have the following writer remove any wal-index hash-table entries left by the interrupted transaction. (check-in: ed77556a user: dan tags: trunk)
02:24
Remove unreachable code associated with WAL from the pager. (check-in: 54c1718e user: drh tags: trunk)

20:27
OOM errors during an auto-checkpoint are benign. (check-in: 3d252ce5 user: drh tags: trunk)
20:24
Remove the walmode.test case from the inmemory_journal test of permutations.test. (check-in: 27ba9c21 user: drh tags: trunk)
17:00
Fix the wal2.test script so that it works in auto_vacuum mode. (check-in: 6a818afb user: drh tags: trunk)
13:57
Change the checksum used in WAL files so that each frames checksum depends on the content of the WAL header and all frame headers and content up to and including the frame to which the checksum is attached. (check-in: 8a53f12c user: dan tags: trunk)
13:28
Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4 user: drh tags: trunk)
12:34
Fix up test_osinst.c to work with SQLITE_OMIT_VIRTUALTABLE. (check-in: 51fd3815 user: drh tags: trunk)
10:39
Change the WAL file format to support two kinds of checksums - one that is fast to calculate on little-endian architectures and another that is fast on big-endian architectures. A flag in the wal-header indicates which the file uses. (check-in: 65ba804d user: dan tags: trunk)
2010-05-22
08:22
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)
