Have sqlite3ota.c use grave accents instead of double-quotes to enclose identifiers in generated SQL. To avoid having the SQL engine substitute a literal string if a column reference cannot be resolved. check-in: 79f24184 user: dan tags: ota-update
14:59
Remove the EXPENSIVE_ASSERTS in pcache.c having to do with the pSynced field of the Pcache object, as they are incorrect, as revealed by recent pcache enhancements. check-in: 69a64560 user: drh tags: trunk
14:54
Ensure the correct collation sequences are used when sorting data in sqlite3ota.c. check-in: 473a72d7 user: dan tags: ota-update

Do not flatten aggregate subqueries that contain min() or max() functions so that if the min()/max() are discarded by the outer query, they still function and cause non-aggregate expression to be evaluated on the minimal or maximal row. check-in: 0bdf1a08 user: drh tags: trunk
12:18
Have the sqlite3_index_writer() VMs check that the final values of records inserted into indexes on rowid tables are integers. check-in: cca376bf user: dan tags: ota-update
11:14
Adjust comments to show that subquery flattening restriction (10) was removed from the code back in 2005. This is a comment change only. check-in: 4ff0eb96 user: drh tags: trunk
10:44
Add OP_Affinity opcodes to the VMs generated by sqlite3_index_writer(). check-in: b9b38cb8 user: dan tags: ota-update

Fix the sqlite3_user_change() interface so that it does allow a non-admin user to change their own password. check-in: 52d440c7 user: drh tags: user-auth
14:01
Move user authentication blocking from sqlite3_prepare() over to the table lock generator, thus allowing SQL statements (like "PRAGMA locking_mode") that do not touch database content to run prior to authentication. check-in: 70121e7c user: drh tags: user-auth
13:44
Add support for the extra parameter on the sqlite3_set_authorizer() callback and support for failing an ATTACH with an authentication-required database using bad credentials. The extension is now feature complete, but much testing and bug-fixing remains. check-in: 596e728b user: drh tags: user-auth
00:27
Reorder parameters on the sqlite3_user_*() interfaces for consistency. Add the first TCL test cases. check-in: 2f6d8f32 user: drh tags: user-auth
2014-09-10

18:41
Add new interfaces to the loadable extension mechanism. check-in: 18d80cbc user: drh tags: 64-bit-lengths
17:27
Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_texte64(), sqlite3_result_blob64(), and sqlite3_result_texte64(). Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface.

03:16
Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle.

Closed-Leaf check-in: c41df393 user: drh tags: omit-fstat-after-unlink
13:11
Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list.

2014-06-06
20:49
Add a test case to ensure that estLog() works for negative numbers. check-in: 813469d9 user: drh tags: trunk

Make sure the estLog() routine in the query planner handles negative values correctly (always returning 1). Prior to this change, estLog(-1) would return a large number which could throw off the cost computations in the query planner in obscure circumstances. check-in: 75437bee user: drh tags: trunk
17:09
Fix an obsolete comment on the whereRangeScanEst() routine. No changes to code. check-in: b16bf851 user: drh tags: trunk
