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. Some tests are currently failing due to an incomplete port. This is an incremental check-in. check-in: 17f8d5e1 user: drh tags: checkindex
13:09
Minor cleanup in checkindex.c. Add progress displays when checking a single index in the top-level TCL script for sqlite3_checker. check-in: 3ca31cc3 user: drh tags: checkindex

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: d655bfab user: dan tags: readonly-wal-recovery
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
12:20
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

Extra ".selecttrace" output following aggregate analysis. No changes to production builds. check-in: 6fbf74ab user: drh tags: trunk
17:34
Fix an error in the previous commit on this branch. check-in: f71dfee0 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: 5492f457 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: 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

Do not flatten subqueries that contain an ORDER BY or GROUP BY clause and can be implemented using a co-routine. check-in: 042d655d user: drh tags: prefer-coroutine-sort-subquery
17:29
Remove the (undocumented) query-planner control that prevents a "SELECT ALL" subquery in FROM clause from being implemented as a co-routine. This control was added by [a29e117d7ec], where it was called a "stop-gap". check-in: ff2f5a31 user: drh tags: trunk
16:56
Fix over-length source code lines in select.c. No logic changes. check-in: fd3267ef user: drh tags: trunk
13:47
Fix an issue introduced by check-in [4cd2a9672c59] (2017-03-03) that could allow a negative value in the 3rd parameter to memmove() when defragmentPage() is called on a btree page with a corrupted freeblock list. The corruption is now detected early and results in an SQLITE_CORRUPT return before the memmove() is reached. check-in: 5b9ae693 user: drh tags: trunk
01:58

2017-09-27
16:51
Disable tests for the LIKE optimization when ICU is enabled, since the LIKE optimization only works for the built-in LIKE operator and ICU overrides the built-in. check-in: f5ef2e1b user: drh tags: trunk
2017-09-25
09:37
Add an extra snapshot related test case. check-in: 24a95e14 user: dan tags: trunk

12:52
Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. check-in: 403b88a8 user: drh tags: trunk
00:24
Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. check-in: 0a12915b user: drh tags: trunk

In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. check-in: 5d03c738 user: drh tags: trunk
20:03
In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. check-in: fa3f5bcc user: drh tags: trunk

Fix a potential use of an uninitialized pointer in RTree following an OOM error. check-in: fd4ec0cd user: drh tags: trunk
10:24
Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. check-in: 65765222 user: drh tags: trunk
01:04
Revert one performance improvement changes from check-in [3b3e32d4cd07] as it was causing a reference to an uninitialized value. check-in: f8b1c64d user: drh tags: trunk

13:16
Minor simplification of error message generation during compound query code generation. check-in: a9447193 user: drh tags: trunk
09:40
The out-of-bounds read on recovery fix of check-in [378afa16381a222a] caused problems for some corner-case error conditions. This alternative fix appears to work better. check-in: 74f399d8 user: drh tags: trunk

Fix the CSV virtual table extension so that it works when the default character is unsigned. check-in: 42f07775 user: drh tags: trunk
2017-09-17
19:45
Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. check-in: 29227d00 user: drh tags: trunk
2017-09-16
