27 check-ins using file src/test_vfs.c version a2d320ea

2010-05-31
06:38
Changes to the way one of the WAL/OOM tests works. (check-in: 15abbc34 user: dan tags: trunk)
2010-05-29
08:40
Add tests to fkey2.test to check that ON CONFLICT clauses do not affect SQLite's behaviour when an FK constraint is violated. (check-in: e9e5b100 user: dan tags: trunk)
06:18
Minor changes to checksum related test cases. (check-in: 60c22bde user: dan tags: trunk)
2010-05-28
11:16
Add a test to walcksum.test to stress the checksum calculation. (check-in: 778d0c17 user: dan tags: trunk)
2010-05-26
17:31
Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. (check-in: 42705bab user: drh tags: trunk)
15:06
Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de0073 user: drh tags: trunk)
2010-05-25
15:53
Updated header comments in wal.c. No functional code changes. (check-in: 687632a6 user: drh tags: trunk)
15:23
Add a busy-handler to a test case in walthread.test to prevent errors. (check-in: d3d348aa user: dan tags: trunk)
13:49
Modify walcrash2.test so that it works with DEFAULT_AUTOVACUUM=1. (check-in: 77438882 user: dan tags: trunk)
13:40
Update header comments in wal.c to correctly describe the WAL file format. Update the locking region offsets in os_unix.c and os_win.c and add assert() statement to verify that the locking region offsets are correct. (check-in: 40030c07 user: drh tags: trunk)
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)
2010-05-24
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)
