Change the OP_Rowid opcode so that a deferred OP_Seek is pending, it simply pulls the rowid from the deferred seek target and does not actually move the cursor or do a seek. Other where.c cleanups. (CVS 6536) (check-in: 1c508a99 user: drh tags: trunk)

Get the behavior of SQLITE_HAVE_ISNAN right. It was reversed in check-in (6517). Ticket #3809. (CVS 6518) (check-in: 97c6ea23 user: drh tags: trunk)
11:57
Add the SQLITE_HAVE_ISNAN compile-time option which, if present, causes SQLite to use the math library isnan() function rather than its own homebrew implementation of isnan(). (CVS 6517) (check-in: 54d23521 user: drh tags: trunk)
11:56
Check-in (6514) did not completely remove the obsolete test, resulting in a segfault. This check-in finishes the job. Ticket #3802. (CVS 6516) (check-in: c29b37ea user: drh tags: trunk)

nMax can be zero and subtracting 1 from an unsigned zero produces undesirable results (CVS 6506) (check-in: a117d82d user: aswift tags: trunk)
12:58
Change the sqlite3_bind_value() implementation to use a default branch on the type switch so that there are no untested jumps in the switch. (CVS 6505) (check-in: d0a8bd6a user: drh tags: trunk)

2009-04-11
19:09
Fix malloc5.test so it work on both 64-bit and 32-bit systems. The ::tcl_platform(wordSize) variable has to be used to adjust some memory sizes. (CVS 6499) (check-in: ea20f78e user: drh tags: trunk)

11:38
Increase the hard upper bound on the number of pcache pages in test_pcache when the test harness is compiled for in-memory temp tables. Some of the test cases need to extra memory to avoid unplanned out of memory errors. (CVS 6494) (check-in: 7f2d6a0b user: drh tags: trunk)
10:25
Replace invocation of (really_finish_test) from async.test with (finish_test). Otherwise a tcl exception may be thrown when running permutations. (CVS 6493) (check-in: e6465e9d user: danielk1977 tags: trunk)
09:51
In sqlite3PagerMovepage(), avoid holding a reference to page number X when calling sqlite3PcacheRekey() to move another page to page number X. (CVS 6492) (check-in: 4447c94f user: danielk1977 tags: trunk)

18:32
Do not run io.test as part of the inmemory_journal permutation. io.test uses the tcl API to test for journal files in the file-system (which of course never exist when running with in-memory journals). (CVS 6487) (check-in: 493f03bd user: danielk1977 tags: trunk)

14:02
Remove misuse detection from the deprecated sqlite3_transfer_bindings() interface. The code was hard to test and was simply taking up space. (CVS 6476) (check-in: 4cd82910 user: drh tags: trunk)
01:23
Enhance sqlite3_shutdown() so that it automatically invokes sqlite3_reset_auto_extension(). This is a harmless no-op if applications are already calling sqlite3_reset_auto_extension() prior to sqlite3_shutdown(). And it prevents possible memory corruption if they do not. So it works either way. Most of the changes are to the test cases. (CVS 6475) (check-in: 0c41f7cf user: drh tags: trunk)
2009-04-08
23:05
Simplify the implementation of the columnName() function in vdbeapi.c. This is a code cleanup only - no behavior changes. (CVS 6474) (check-in: 0628f586 user: drh tags: trunk)
23:04
Add an assert() to the implementation of count(*) that checks the correct operation of the sqlite3_aggregate_count() function. (CVS 6473) (check-in: f322be38 user: drh tags: trunk)

13:51
Minor refactoring of the expression-compaction logic for clarity of presentation. New comments added. The EXPRDUP_DISTINCTSPAN flag is removed as obsolete. (CVS 6470) (check-in: 44ded2ea user: drh tags: trunk)
12:21

11:49
Add a comment to printf.c - no changes to code. (CVS 6468) (check-in: ee5a4a0e user: drh tags: trunk)
2009-04-07
22:06

09:16
Have OP_IdxRowid handle the case where the index entry it is reading from is deleted. (CVS 6461) (check-in: cdad29b5 user: danielk1977 tags: trunk)

00:43

00:35

11:11
Check-in (6450) introduced the possibility of calling memset() with a negative 3rd argument. This fixes that bug. Ticket #3777. (CVS 6452) (check-in: 8ca612c4 user: drh tags: trunk)
2009-04-05
15:18

2009-04-03
12:12
Remove a blank line in sqlite.h.in that was preventing the SQLITE_LOCKED_SHAREDCACHE constant appears in the automatically-generated documentation. Ticket #3775. (CVS 6446) (check-in: 65f9d3b9 user: drh tags: trunk)
12:04
