2017-11-13
05:51
Remove some branches in walTryBeginRead() that were added by check-in [ce5d13c2de] but became unreachable with the addition of logic in check-in [18b26843] that enabled read-only clients to parse the WAL file into a heap-memory WAL-index, thus guaranteeing that the WAL-index header is always available. check-in: 9c6b38b9 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

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

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

18:31
Add the "sqlite3_imposter DB SCHEMA ROOT SQL" command to sqlite3_checker. Use it to fix the checkindex01.test module. There are still errors reported by the checkfreelist01.test module. check-in: 0593a2ba user: drh tags: checkindex
18:05
Move the test scripts for checkfreelist and checkindex over into the ext/repair/test directory. Run them now using the sqlite3_checker utility with the --test option.

01:05
When sqlite3_checker finds a problem, show the row key as part of the error message, not the row index number. check-in: 6ffe917d user: drh tags: checkindex

08:04
Fix an issue in incremental_index_check with indexes that use non-default collation sequences. check-in: 3ebb2351 user: dan tags: checkindex
2017-10-28
20:54
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
20:31
Fix "after" parameter handling in the incremental_index_check code. check-in: c40c3c62 user: dan tags: checkindex

Add test cases from OSSFuzz to prevent a regression in co-routine processing. check-in: 689743d8 user: drh tags: trunk
2017-10-27
23:28
I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down. Closed-Leaf check-in: 0926df09 user: drh tags: mistake
20:53
Add the start of the "incremental_index_check" virtual table in ext/repair/checkindex.c. For incremental verification of index contents. check-in: d5b9dada user: dan tags: checkindex

17:34
Fix an error in the previous commit on this branch. check-in: f71dfee0 user: dan tags: readonly-wal-recovery
17:05

15:21
Fix a bug causing "make amalgmation-autoconf" to create an invalid package if either the current or parent directory contains a file named install.sh or install-sh. check-in: e1faa785 user: dan tags: trunk
2017-10-25
23:28

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
