| ||
| 21:01 | Improved fix for ticket [da78413751863] that does not require disabling the query flattener as was done in [005d5b870625]. This also makes the code generator for vector IN operators a little easier to understand. (check-in: 723f1be3d4 user: drh tags: trunk) | |

|
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: 9c6b38b9a9 user: drh tags: readonly-wal-recovery) | |
|
2017-11-11
| ||

| 19:26 | Extra comments on the sqlite3OsShmMap() call in walBeginUnlocked(). No changes to code. (check-in: 033ee92bf4 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: 04974a8b5c user: drh tags: readonly-wal-recovery) | |
| 17:32 | Change the name of SQLITE_READONLY_CANTLOCK to SQLITE_READONLY_CANTINIT. (check-in: 6d7f94faa7 user: drh tags: readonly-wal-recovery) | |
|
2017-11-07

| 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: 5a6703fc3f 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: ba718754fa user: dan tags: readonly-wal-recovery) | |
| 09:08 | Add fault-injection tests for the code on this branch. (check-in: a7d949fb73 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: 18b268433d user: dan tags: readonly-wal-recovery) | |
|
2017-11-02
| ||
| 18:57 | Fix test cases in wal2.test broken by the locking change in the previous commit. (check-in: f569c35172 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: 5190d84a29 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: ce5d13c2de user: dan tags: readonly-wal-recovery) | |

| 06:59 | Fix a race condition in os_unix.c that might allow a client to use a *-shm file corrupted by a power failure if another client fails between locking the *-shm file and truncating it to zero bytes. (check-in: d655bfabd1 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: bb39744f4b user: drh tags: trunk) | |
| 12:20 | Fix redundancies in the makefiles that resulted from moving shell.c over to shell.c.in. (check-in: bf09fa683e user: drh tags: trunk) | |

| 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: 457eedfac0 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: d17ef7d153 user: drh tags: trunk) | |
| 12:20 | Add test cases from OSSFuzz to prevent a regression in co-routine processing. (check-in: 689743d8e3 user: drh tags: trunk) | |
|
2017-10-27

| 17:34 | Fix an error in the previous commit on this branch. (check-in: f71dfee06c user: dan tags: readonly-wal-recovery) | |
| 17:05 | Instead of extra locks, use F_GETLK to ensure that readonly_shm clients cannot connect to a wal-mode database if there are no writers. (check-in: 5492f457dc user: dan tags: readonly-wal-recovery) | |
| 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: e1faa78594 user: dan tags: trunk) | |
|
2017-10-25

| 18:00 | Fix compilation issue (C99-ism) seen with MSVC. (Closed-Leaf check-in: 61870b42b0 user: mistachkin tags: rtree-integrity-check) | |
| 16:38 | Add SQL scalar function rtreecheck() to the rtree module. For running checks to ensure the shadow tables used by an rtree virtual table are internally consistent. (check-in: dde0bb3eab user: dan tags: rtree-integrity-check) | |
| 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: adfa7ed2de 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: 1e30f4772d user: drh tags: trunk) | |
