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
22:46
Complete the implementation of the various APIs. Fix several problems. This is another incremental check-in that does not completely work. check-in: 4eaaa7fa user: drh tags: user-auth
19:01
Add the ".user" shell command and implement the sqlite3_user_add() routine. Incremental check-in. The code compiles but does not work. check-in: a0455f9d user: drh tags: user-auth
17:34
Further ideas on user authentication. Not yet working code. check-in: c8171ecd user: drh tags: user-auth
2014-09-09

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. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. check-in: 94954850 user: drh tags: 64-bit-lengths
14:47
Non-working preliminary implementation attempts on user authentication. check-in: 8440f093 user: drh tags: user-auth

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

02:00
Fix a couple of typos in comments. No changes to code. check-in: a758465e user: mistachkin tags: trunk

2014-09-03
19:30
Split part of "PRAGMA ota_mode" off into "PRAGMA pager_ota_mode". This allows some specialized custom VFS implementations to intercept and implement the expected pager-related effects of this pragma. check-in: 209f672e user: dan tags: ota-update
08:25
Add a command line program that uses the extension. This serves as example code and is also useful for performance testing. check-in: ffa1524e user: dan tags: ota-update

18:11
Fix a problem in calculating the costs of "OR" scans. check-in: 9bbca48b user: dan tags: trunk

15:00
Add text to the header comment of whereLoopAddBtree() describing how the costs of various b-tree loops are estimated. Closed-Leaf check-in: 05e6e16c user: dan tags: experimental-costs

19:34
The trunk assumes that an open range constraint on an indexed term (col>?) term matches 1/4 of the indexed rows, and that a closed constraint (col BETWEEN ? AND ?) matches 1/64. Change this branch to do the same. check-in: 4047ac75 user: dan tags: experimental-costs

Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. check-in: 88a5758d user: dan tags: experimental-costs
08:49
Fix an error in estimating of the number of rows visited by a range scan. check-in: d491de62 user: dan tags: experimental-costs
