18:47
Corrections to comments on the whereScanInit() interface. check-in: ab7ab415 user: drh tags: trunk
16:49
For DELETE operations, make sure that seeks on the main table are not deferred, since if they are and none of the indexes reference columns of the table, the seek might never occur until the OP_Delete opcode, which is too late. Fix for ticket [16c9801ceba49]. check-in: 93a2bace user: drh tags: trunk
16:30
Fix an error in main.mk causing testfixture to use individual fts5 source code files instead of fts5.c. check-in: 933a1c81 user: dan tags: trunk
16:06
In the WHERE generator, when building code for a DELETE operation, make sure that seeks to the main table are not deferred. This is a better fix for the [16c9801ceba49] bug than the previous. Closed-Leaf check-in: 150dd09e user: drh tags: ticket-16c9801ce
15:16
Fix a bug in sqlite_analyzer causing it report (slightly) incorrect values for the number of entries in indexes or WITHOUT ROWID tables. check-in: dc37750d user: dan tags: trunk
11:31

2016-05-05
23:59
Additional error reporting. Open the source database read/write so that it can delete the WAL file when done. check-in: d2efd3c1 user: drh tags: scrub-backup

Fix typo in comment. No changes to code. check-in: 6c43ba1c user: mistachkin tags: trunk
14:45
Only disable the one-pass DELETE optimization if the WHERE clause contains a correlated subquery. Uncorrelated subqueries are allowed. This is a refinement of check-in [3f221f592a9a1] that is the fix for ticket [dc6ebeda9396087]. check-in: aae38969 user: drh tags: trunk
14:20
Portability enhancements to the configure script on the amalgamation tarball. check-in: 7184c4b8 user: drh tags: trunk

2016-05-03
19:40
Minor style tweaks in the MSVC makefile. check-in: 1b43358f user: mistachkin tags: trunk

The session extension is disabled by default. To enable it using --enable-session on ./configure on unix and add SESSION=1 to the nmake on Windows. Or add -DSQLITE_ENABLE_SESSION and -DSQLITE_ENABLE_PREUPDATE_HOOK to build manually. check-in: bcaa650e user: drh tags: trunk
13:14
Turn the session extension off by default. Enable using --enable-session on configure scripts, or using the SESSION=1 argument to nmake on Windows. Closed-Leaf check-in: e462cde2 user: drh tags: session-make

Remove some randomness from test script temptable2.test. check-in: 5830cf72 user: dan tags: trunk
16:59
Fix a test case in temptable2.test so that it works on systems that lack a coherient cache (ex: OpenBSD) and thus do not support the "PRAGMA mmap_size" command. check-in: 088cf838 user: drh tags: trunk
13:57
Fix harmless LLVM compiler warnings in the srcck1.c utility program used during the build process. check-in: e4af9675 user: drh tags: trunk
12:18
Disable the multi-row one-pass DELETE optimization when the WHERE clause contains a subquery. Fix for ticket [dc6ebeda9396087]. check-in: 3f221f59 user: drh tags: trunk

Change the way tester.tcl handes $argv so that in "permutations.test <permutation> <filename>" <filename> may be the name of any file in the test/ directory. check-in: 820c57bb user: dan tags: trunk
18:10
Remove an unnecessary branch from the OP_String8 opcode. check-in: 459a0b45 user: drh tags: trunk

10:13
Fix an almost entirely harmless buffer overread in the sessions module. Closed-Leaf check-in: 89b0ee33 user: dan tags: permutations-fix
02:55

Remove an unnecessary conditional from the sqlite3DecOrHexToI64() routine. check-in: fcf85bfe user: drh tags: trunk
00:32
Change the sqlite3Atoi64() routine so that it returns failure if not all of the input characters are consumed, even if it consumed all characters up to the first 0x00. This has no impact on external APIs as far as I can tell. check-in: 46d4ffff user: drh tags: trunk
2016-04-27
18:54
Modify the permutations.test script so as to set any permutation specific configuration values before running each individual test script. check-in: 2662d8fe user: dan tags: permutations-fix
15:24
More simplification of the sqlite3AtoF() routine. Add special comments to indicate branches that are for optimization purposes only and that give the correct answer even if always or never taken. check-in: 0065fe97 user: drh tags: trunk
11:24
Fix a couple of test script problems on this branch. Both related to the fact that temp database page sizes can no longer be changed by VACUUM or the backup API after the temp db is populated. check-in: 6bb5aa2b user: dan tags: tempfiles-25
02:35
Remove still more unnecessary branches from sqlite3AtoF(). check-in: 3adfe9f3 user: drh tags: trunk

18:13
Add the sqlite3rbu_vacuum() API, to create an RBU handle that can be used to rebuild a database in the same way as the VACUUM command. check-in: bd4a6f83 user: dan tags: trunk
16:44
If a call to sqlite3rbu_close() on an rbu handle opened by sqlite3rbu_vacuum() returns other than SQLITE_OK, delete the contents of the rbu_state table. This ensures that if an RBU vacuum operation either completes successfully or encounters an error, the next call to sqlite3rbu_vacuum() with the same parameters starts a new RBU vacuum operation. Closed-Leaf check-in: 6e4ac704 user: dan tags: rbu-vacuum

01:58
Test cases for SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION. Closed-Leaf check-in: debafa5e user: drh tags: load-ext-security
01:30
Revert sqlite3_enable_load_extension() to its original long-standing behavior. Add SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION which will enable only the C-API and leave the SQL function disabled. check-in: b2ae5bfa user: drh tags: load-ext-security
2016-04-20
20:08
Add a documentation comment for sqlite3rbu_vacuum() to sqlite3rbu.h. check-in: da5c753d user: dan tags: rbu-vacuum

When an error occurs while transitioning out of WAL mode, make sure the locking state is not left at EXCLUSIVE. check-in: 3340f086 user: drh tags: trunk
18:31
Fix a locking race condition in Windows 10 that can occur when two or more processes attempt to recover the same hot journal at the same time. check-in: 38a4e9d9 user: drh tags: trunk
17:47
Add fault injection tests for rbu vacuum. Fix some problems revealed by the same. check-in: f042fdd1 user: dan tags: rbu-vacuum
00:30
API Change: Modify sqlite3_enable_load_extension() so that it only enables/disables the load_extension() SQL function, and leaves the C-APIs enabled at all times. In this way, applications can enable extension loading for the C interface without having to expose that capability to the SQL. check-in: edb454e4 user: drh tags: load-ext-security
2016-04-19
19:27
Updates to ensure the values of PRAGMA settings like "page_size", "auto_vacuum", "user_version" and "application_id" are not lost when a database is RBU vacuumed. check-in: 74ffea76 user: dan tags: rbu-vacuum
17:11
When an RBU vacuum is started on a db identified using a URI filename, pass the same URI parameters when creating the new version of the db. This ensures that RBU vacuum works with password protected databases. check-in: ca021ba8 user: dan tags: rbu-vacuum
16:20
Detect attempts to use rbu vacuum on a wal mode database (not allowed). And attempts to write to a database in the middle of an rbu vacuum (which prevents the vacuum from resuming). check-in: 00b2f4b0 user: dan tags: rbu-vacuum
2016-04-18
21:00
Another fix to rbu vacuum for a zipvfs case. check-in: 29407d70 user: dan tags: rbu-vacuum

13:09
The last parameter to pread64() and pwrite64() should be off64_t, not off_t. check-in: 3a7d7298 user: drh tags: trunk
09:17
Add the -vacuum switch to the "rbu" demonstration program. check-in: 9a0078a5 user: dan tags: rbu-vacuum

Changes so that rbu vacuum works with zipvfs databases. check-in: bae7f875 user: dan tags: rbu-vacuum
17:53
Avoid creating any extra files ("<target>-vacuum") when running an RBU vacuum. Ensure that the OAL file created is "<target>-oal", not "<target>-vacuum-oal". check-in: dc19aacc user: dan tags: rbu-vacuum
15:03

16:27
Skip-ahead is now just an optimization. If it gets confused, it falls back to an incremental scan with redundancy elimination. check-in: 6fac0b92 user: drh tags: skip-ahead-distinct
16:17
Skip-ahead does not always work. So we still have to check for redundancy. check-in: db5a2364 user: drh tags: skip-ahead-distinct
15:54
Fixes to the skip-ahead distinct logic. More issues remain. check-in: 45a70b2b user: drh tags: skip-ahead-distinct

15:38
Add some missing testcase() macros to the pushDownWhereTerms() routine. check-in: 67d7f79c user: drh tags: trunk
13:35
Rename WhereInfo.pResultSet to pDistinctSet to more accurately reflect what it represents. check-in: 53179614 user: drh tags: trunk
13:16
Since the return value of sqlite3OsClose() is always ignored, we might as well make it "void" instead of "int", and thereby save 50 bytes in the compiled binary. check-in: 7ee570e7 user: drh tags: trunk
13:06
Additional ".selecttrace" debugging output when the query is transformed from a DISTINCT into a GROUP BY. check-in: 5a469145 user: drh tags: trunk
2016-04-13
