Extra comments on the sqlite3OsShmMap() call in walBeginUnlocked(). No changes to code. check-in: 033ee92b user: drh tags: readonly-wal-recovery
17:51
Turns out that SQLITE_READONLY_CANTLOCK is an historical name that must be preserved. So make a new SQLITE_READLOCK_CANTINIT name instead. check-in: 04974a8b user: drh tags: readonly-wal-recovery
17:32
Change the name of SQLITE_READONLY_CANTLOCK to SQLITE_READONLY_CANTINIT. check-in: 6d7f94fa user: drh tags: readonly-wal-recovery

Update an assert in wal.c. check-in: 94527b89 user: dan tags: readonly-wal-recovery
21:15
Handle the race condition that may occur if another process connects and then checkpoints and truncates the wal file while a readonly-shm client is building its heap-memory wal-index. check-in: 5a6703fc user: dan tags: readonly-wal-recovery
15:43
On unix, if the *-shm file cannot be opened for read/write access, open it read-only and proceed as if the readonly_shm=1 URI option were specified. check-in: ba718754 user: dan tags: readonly-wal-recovery
09:08
Add fault-injection tests for the code on this branch. check-in: a7d949fb user: dan tags: readonly-wal-recovery

2017-11-04
21:06
Add further tests for the code added on this branch. check-in: a6716fcd user: dan tags: readonly-wal-recovery
18:10
In cases where a readonly_shm client cannot take the DMS lock on the *-shm file, have it parse the wal file and create a wal-index to access it in heap memory. check-in: 18b26843 user: dan tags: readonly-wal-recovery
2017-11-02
18:57

11:12
Avoid locking shm-lock WAL_READ_LOCK(0) during recovery. Doing this allows recovery to proceed while a readonly_shm connection in unlocked mode has an ongoing read transaction. check-in: 5190d84a user: dan tags: readonly-wal-recovery
2017-11-01
20:59
If a readonly_shm connection cannot map the *-shm file because no other process is holding the DMS lock, have it read from the database file only, ignoring any content in the wal file. check-in: ce5d13c2 user: dan tags: readonly-wal-recovery
07:06
Merge latest trunk changes into this branch. check-in: 985bfc99 user: dan tags: readonly-wal-recovery

2017-10-31
14:56
Update the built procedures for the sqlite3_analyzer utility to allow it to be linked with an external sqlite3.o library. Automatically detect a missing dbstat extension and report the compile-time error. check-in: bb39744f user: drh tags: trunk

Increase the version number for the next release - which is still months away but there have been significant query planner enhancements since the previous release. check-in: 457eedfa user: drh tags: trunk
20:51
Reactivate query flattening when the result set of the outer query has no function calls or subqueries. This is a partial reversal of check-in [c9104b59]. Co-routines are still preferred if the outer query has a complex result set, but for simple results sets, query flattening is used. Check-in [4464f40ccd7] is completely backed out due to this change. check-in: d17ef7d1 user: drh tags: trunk
12:20
Add test cases from OSSFuzz to prevent a regression in co-routine processing. check-in: 689743d8 user: drh tags: trunk

16:14
Do not reference the ioctl() system call in the unix backend unless it is actually needed by the Batch Atomic Write extension. This should allow the build to work on VxWorks. check-in: adfa7ed2 user: drh tags: trunk
01:34
Add the sqlite_btreeinfo eponymous-only table for introspecting the schema and estimating the sizes of various btrees. check-in: 1e30f477 user: drh tags: trunk
