49 check-ins using file Makefile.in version 6b572807

2016-11-30
16:39
Merge all the latest changes from trunk. check-in: 7ca58a07 user: drh tags: est_count_pragma
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
Simplify some code in fts5_expr.c. Add some extra test cases for the same. check-in: 7cc2d60d user: dan tags: trunk
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 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

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

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
Fix a bug in sqlite3_snapshot_recover() that could cause subsequent read transactions to use out-of-data cache entries. check-in: 9abeb798 user: dan tags: serializable-snapshot
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

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
