48 check-ins using file main.mk version 488af865

2016-11-30
14:47
Fix then handling of the (oversized) integer literal -0x8000000000000000. (check-in: 3816bb41 user: drh tags: trunk)
05:08
Change the OP_DecrJumpZero opcode back to its old behavior of always decrementing, except top the decrementing when it reaches the largest negative number. (check-in: 9d0d8c2e user: drh tags: trunk)
04:07
More improvements to boundary cases in the date/time functions, flowing out of branch coverage testing. (check-in: 1218005a user: drh tags: trunk)
01:05
Prevent a warning about integer overflow when using a very large negative LIMIT. (check-in: 96106d56 user: drh tags: trunk)
00:48
Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. (check-in: dc453b34 user: drh tags: trunk)
2016-11-29
20:39
The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31. Change the actually implementation so that the answer given is really NULL. This also avoids unnecessary hand-wringing over an signed integer overflow that might otherwise occur when processing out-of-bound dates. (check-in: d410a839 user: drh tags: trunk)
2016-11-28
21:22
Fix broken hyperlinks to the sqlite3_snapshot objection definition in the documentation. No changes to code. (check-in: 9021f687 user: drh tags: trunk)
14:52

2016-11-26
19:44
Add the sqlite3_snapshot_recover() interface and related functionality. (check-in: b70c85ce user: drh tags: trunk)
2016-11-25
20:20
Clarification of the behavior of sqlite3_stmt_readonly() on BEGIN IMMEDIATE statements. The is comment changes only - no changes to code. (check-in: a4205a83 user: drh tags: trunk)
19:32
Remove the OP_RowKey opcode. Use OP_RowData in its place. (check-in: 6ac7b07a user: drh tags: trunk)
19:18
Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively. This is a continuation of the optimization started by check-in [2d831074cf]. The result is a slightly smaller and faster binary. (check-in: 49ebc219 user: drh tags: trunk)
17:03
Small performance increase and size reduction in the OP_Column opcode. (check-in: a9498407 user: drh tags: trunk)

Performance enhancement to sqlite3_snprintf(). (check-in: c53dca7f user: drh tags: trunk)
15:11
Performance improvement in sqlite3StrAccumFinish() for the common case where no memory allocation is required. (check-in: b6acf5d4 user: drh tags: trunk)
14:30
Add a comment to help clarify the EP_FromJoin hack in exprCodeBetween(). (check-in: 6df7c574 user: drh tags: trunk)
2016-11-23
23:18
Fix the error message for invalid ".mode" arguments in the command-line shell, so that it mentions the new "quote" mode. (check-in: 9a603a18 user: drh tags: trunk)
19:31
Code constant vector components outside of any loops in CASE and BETWEEN expressions. Fix for [1a684656]. (check-in: c08aff13 user: dan tags: trunk)
14:19
Correctly display the names of SQL functions in the VDBE_PROFILE output. (check-in: 161192f1 user: drh tags: trunk)
2016-11-22
22:23
Merge bug fixes and enhancements from trunk. (Closed-Leaf check-in: e2c4bdf5 user: drh tags: serializable-snapshot)
21:11
Enclose the sqlite3WalSnapshotRecover() routine within (check-in: e7be3183 user: drh tags: serializable-snapshot)
20:29
Add a new requirement mark for CAST expressions. (check-in: bee2859b user: drh tags: trunk)
19:15
Update requirement marks to reflect changes in wording in the documentation. No changes to code. (check-in: f5ac98ef user: drh tags: trunk)
01:26
Remove unnecessary OP_Close opcodes for a size reduction and performance increase. (check-in: 32be7aae user: drh tags: trunk)
2016-11-21
21:33
Remove unnecessary OP_Close opcodes at the end of INSERT operations, resulting in smaller and faster code. (check-in: abeddb6d user: drh tags: trunk)
18:15
Enhance speedtest1.c so that is works on older versions of SQLite, before the introduction of the group_concat() aggregate function. (check-in: 9979ba80 user: drh tags: trunk)
2016-11-20
17:59
Fix harmless compiler warnings. (check-in: b3b7b42d user: drh tags: trunk)
12:00
Prevent a possible use-after-free bug in the query optimizer. (check-in: 0a98c8d7 user: drh tags: trunk)
2016-11-19
18:31
Remove the requirement to open the wal file before sqlite3_snapshot_recover() is called. Also add some comments to new functions. (check-in: 28393c41 user: dan tags: serializable-snapshot)
17:30
Test some extra error conditions in sqlite3_recover_snapshot(). (check-in: db314213 user: dan tags: serializable-snapshot)
17:20
Add another fault-injection test for sqlite3_snapshot_recover(). (check-in: 7e040406 user: dan tags: serializable-snapshot)
16:35
Fix a problem causing sqlite3_snapshot_recover() to return SQLITE_IOERR_SHORT_READ. (check-in: 525f75fa user: dan tags: serializable-snapshot)
14:53

2016-11-18
20:49
Add experimental sqlite3_snapshot_recover() API. (check-in: 174a6076 user: dan tags: serializable-snapshot)
18:43
Require that the database handle be in autocommit mode for sqlite3_snapshot_get() to succeed. This is because it may open a read transaction on the database file. (check-in: 83b658da user: dan tags: serializable-snapshot)
18:22
Add tests for snapshot interfaces. (check-in: 1f7ee7af user: dan tags: serializable-snapshot)

2016-11-17
21:52
Experimental changes for faster in-memory DB operation for large databases. (Closed-Leaf check-in: 4fe94b0f user: drh tags: memdb-opt)
20:05
Fix a problem in rtreeD.test causing it to fail in OMIT_BUILTIN_TEST builds. (check-in: d6b3779e user: dan tags: trunk)
13:54
Change the --enable-debug option on configure so that it enables the ".selecttrace" and ".wheretrace" commands in the command-line shell. (check-in: 2331192b user: drh tags: trunk)
13:13
Disable the query flattener optimization for SELECT statements that are on the RHS of vector IN operators. This is a hack that fixes the bug described in ticket [da7841375186386c]. A better solution that does not disable the query flattener is needed, but this will server for the time being. (check-in: 005d5b87 user: drh tags: trunk)
2016-11-15
21:17
Add a needed #include to speedtest1.c. (check-in: 77aeb705 user: drh tags: trunk)

02:46
Make the VACUUM command about 9% faster by avoiding unnecessary calls to sqlite3BtreeMovetoUnpacked() while copying rowid tables. (check-in: 5ed0bd38 user: drh tags: trunk)
2016-11-14
20:47
Add 8794 new test cases received from the OSS-FUZZ project. (check-in: 03f75a67 user: drh tags: trunk)
20:08
Fix a potential use-after-free error during parsing of malformed CREATE TABLE statement. (check-in: c5dbc599 user: drh tags: trunk)
18:27
Enhance fuzzcheck.c to accept database-specific configuration parameters in the option CONFIG table. Add the fuzzdata5.db fuzz database containing test cases from OSS-FUZZ. (check-in: a71fad45 user: drh tags: trunk)
