15:55
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. (check-in: a21ffcd8 user: drh tags: branch-3.27)
15:43
This was originally intended to be the 3.27.2 release, but then I realized that I left out an important patch. (Closed-Leaf check-in: 6c5e5e2e user: drh tags: mistake)

2019-02-23
00:56
Import from trunk the new fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: 0e64ac12 user: drh tags: branch-3.27)
2019-02-20
13:14

21:06
Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. (check-in: 1d43ee40 user: drh tags: deferred-free-space)

22:34
Small performance improvement and size reduction for pageFindSlot() - the routine in btree.c that locates a free slot for a cell on a btree page. (check-in: 1969372a user: drh tags: trunk)
20:55
Use a fast compiler-provided memory barrier exclusively, if such a memory barrier is available. (Leaf check-in: df66fec9 user: drh tags: faster-memory-barrier)

Add test cases and fix problems on this branch. (check-in: 2b2e9f81 user: dan tags: reuse-schema)
17:28
Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d212957 user: drh tags: trunk)
15:59
Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. (check-in: 5c499da8 user: drh tags: trunk)
14:59
Merge the fix for ticket [4e8e4857d32d401f], so that this branch now contains release 3.27.1 plus the extra patch to preserve ROWID values on VACUUM. (check-in: 0cdae60e user: drh tags: apple-osx)
14:55
Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. (check-in: 5c663804 user: drh tags: trunk)
13:17
Version 3.27.1 (check-in: 0eca3dd3 user: drh tags: release, branch-3.27, version-3.27.1)
12:46
Cherrypick the fix for ticket [4e8e4857d32d401f] from trunk. (check-in: d5d944d7 user: drh tags: branch-3.27)
12:44
Increase the version number to 3.27.1. (check-in: b94d5428 user: drh tags: branch-3.27)
04:15
Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. (check-in: 440a7cda user: drh tags: trunk)
2019-02-07
19:28
Pull in the change that causes VACUUM to preserve rowid values. (check-in: c9af2f71 user: drh tags: apple-osx)
19:07
Change VACUUM so that it preserves ROWID values. (check-in: 49e5d11d user: drh tags: trunk)
18:49
Merge the offical 3.27.0 release. (check-in: 62829164 user: drh tags: apple-osx)
17:02
Version 3.27.0 (check-in: 97744701 user: drh tags: trunk, release, version-3.27.0)
15:09
Experimental change to VACUUM so that it preserves existing ROWID values. (Closed-Leaf check-in: f264015f user: drh tags: vacuum-preserves-rowid)
00:17
In the fuzzcheck test program, make sure the isspace() and related routines are not given values outside the range of -1 to 255. (check-in: f2983287 user: drh tags: trunk)
2019-02-06
20:49
Ensure all bytes of the PgHdr1 structure are initialized. This avoids a valgrind error when running corruptI.test. (check-in: a505e34d user: dan tags: trunk)
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. (check-in: 0e6249cb user: dan tags: trunk)
19:42
Avoid attempting to delete a file while it is still open in walfault2.test. (check-in: 9d54a63d user: dan tags: trunk)
18:08
Update test file dbfuzz001.test so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK builds. (check-in: 4371a0c4 user: dan tags: trunk)
15:23
Add -DSQLITE_ENABLE_DESERIALIZE to the default testing configuration in test/releasetest.tcl. (check-in: 433d6ef6 user: dan tags: trunk)
13:48
Do not attempt to test the shell ".trace" command in SQLITE_OMIT_TRACE builds. (check-in: 3839e909 user: dan tags: trunk)
13:41
Fix a problem preventing testfixture from being built with SQLITE_OMIT_VIRTUALTABLE. (check-in: d2cca36a user: dan tags: trunk)
01:18
When extending the size of SrcList objects, do not attempt to use extra space on the end of the allocation, as that provides scarcely any performance benefit but does greatly complicate cross-platform testing. (check-in: 3087a0c3 user: drh tags: trunk)
00:55
If the query flattener detects an error, cause the SELECT code generator to abort immediately. (check-in: 3d3b142f user: drh tags: trunk)
00:11
Back out check-in [008112bcef561a8], reenabling deprecated PRAGMAs when the SQLITE_OMIT_DEPRECATED compile-time option is used, because way too many TH3 tests depend on those deprecated PRAGMAs. (check-in: 9dbf512d user: drh tags: trunk)
2019-02-05
20:51
Omit the ".progress" command from the shell if it is compiled with the SQLITE_OMIT_PROGRESS_CALLBACK option. (check-in: 4d0a949f user: drh tags: trunk)
19:52

14:36
The IS NOT NULL operator does not imply that the operand is never NULL. Fix for ticket [5948e09b8c415bc45da5cf] (check-in: d840e9bb user: drh tags: trunk)
12:16
Keep the temp_store_directory and data_store_directory pragmas even when compiling with SQLITE_OMIT_DEPRECATED. (check-in: 93386a7c user: drh tags: trunk)
08:55
Update test file "resetdb.test" so that it works with the "prepare" permutation. (check-in: 95d33812 user: dan tags: trunk)
2019-02-04
21:10
Early detection of implausibly sized records to avoid unnecessary large memory allocations. (check-in: 2c8769c6 user: drh tags: trunk)
19:52
Mention the new -memtrace command-line option in the -help output of the CLI. (check-in: ada91aef user: drh tags: trunk)
19:50
Add the -memtrace option to dbfuzz2. (check-in: 67fecbc7 user: drh tags: trunk)
19:45
Enhance dbfuzz2 so that with the -v option it shows the return code and error message for any failing SQL statements. (check-in: 3a127ef9 user: drh tags: trunk)
19:12
Ensure that the sqlite3_exec() callback gets the correct number of columns for a query, even if the schema changes out from under it. (check-in: a16ffb5a user: drh tags: trunk)
16:42
Do not run shmlock.test as part of the inmemory_journal permutation. (check-in: d3fea69c user: dan tags: trunk)
16:36
