12 check-ins using file src/test_vfs.c version 7fc397aa

2010-05-20
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)
16:45
Convert the wal-header and frame-header to 24 bytes. Extra information in both headers is designed to enhance robustness after crashes, though the extra information is currently unused. This is a snapshot of a work in progress. (check-in: 66970643 user: drh tags: trunk)

23:41
Merge WIN32 WAL support into trunk. Still some issues with locking to resolve. (check-in: 43377663 user: shaneh tags: trunk)
19:39
Add the SQLITE_FCNTL_SIZE_HINT to the os_win.c VFS. (check-in: 9894118d user: drh tags: trunk)
19:26
Add the SQLITE_FCNTL_SIZE_HINT operator to sqlite3_file_control() and use it to give the VFS hints about the ultimate size of a database file when the file is growing. (check-in: 2b7e3b4a user: drh tags: trunk)
19:09
Fix a bug in the new checkpoint computation. Also update the checkpoint algorithm in the test scripts to align with the new implementation. (check-in: 8b6056f2 user: drh tags: trunk)
18:08
Revise the checksumming algorithm in wal.c. More variable refactoring. (check-in: 542b90eb user: drh tags: trunk)
17:49
Refactoring some variable names in wal.c. (check-in: 1d201ff5 user: drh tags: trunk)
01:53
Add a large comment to wal.c describing the WAL and wal-index file formats. (check-in: a71a22b5 user: drh tags: trunk)
2010-05-18
23:29
Update the wal-index hash format so that hash-table space is reused following a rollback, thus preventing hash table overflows. Add assert()s to verify that hash tables do not overfill. Further refactoring of the wal-index code. (check-in: ada9a8c7 user: drh tags: trunk)
18:01
Refactoring of the WalIterator implementation. (check-in: b5b60fdc user: drh tags: trunk)
13:27
Mark the shared-memory in the WAL implementation as volatile. (check-in: 0a678790 user: drh tags: trunk)
