16:50
Avoid attempting to call the xFetch() method of an sqlite3_io_methods object with a version number less than 3. (check-in: dedaa6fb user: dan tags: trunk)
15:34
Merge latest trunk changes with this branch. (check-in: 55b8011d user: dan tags: ota-update)
15:22
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)
14:46
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)
2014-09-12
20:30
Small performance improvement to the dirty list handling in the pager. (check-in: b332a84d user: drh tags: trunk)
17:41
Simplify the way the column cache is managed around OP_Move instructions. (check-in: 32055623 user: drh tags: trunk)
04:28
Fix a problem with parser memory allocation on 32-bit systems. (check-in: 2f69a1fa user: drh tags: trunk)
2014-09-11
23:34
Fix an issue with sqlite3_bind_text64() with the SQLITE_UTF16 encoding parameter. Remove some unreachable code from the text64() and blob64() implementation. (check-in: 34292b08 user: drh tags: trunk)
18:44
Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_text64(), sqlite3_result_blob64(), and sqlite3_result_text64(). Add the sqlite3_msize() interface. Internal memory allocation routines now use 64-bit unsigned length parameters for safety. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 7e4978c0 user: drh tags: trunk)
17:27
Add the SQLITE_USER_AUTHENTICATION extension to the trunk. This extension is disabled by default. Special compilation procedures are need to enable it. (check-in: 65884d4f user: drh tags: trunk)
17:14
Clean up some #includes in the extension API implementation. (Closed-Leaf check-in: b149ef5c user: drh tags: user-auth)
16:36
Suppress the potential schema error that occurs when a non-user-auth SQLite library tries to parse the sqlite_user table definition in a user-auth database. (check-in: cda33c1e user: drh tags: user-auth)
16:19
Enhance the sqlite3_user_add() interface to initialize the user authentication logic. Add test cases for the extra argument on the end of the authorizer callback. (check-in: 842c6da8 user: drh tags: user-auth)
15:25
All interfaces working and tested. (check-in: 96ea5c0b user: drh tags: user-auth)
14:56
Get the sqlite3_user_delete() interface working. (check-in: 974a9c65 user: drh tags: user-auth)
14:40
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
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
20:30
Change the name of the _texte64() interfaces to just _test64(), without the "e". (Closed-Leaf check-in: 6ab76c5f user: drh tags: 64-bit-lengths)
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. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. (check-in: 27e3ca3e user: drh tags: trunk)
02:00
Fix a couple of typos in comments. No changes to code. (check-in: a758465e user: mistachkin tags: trunk)
01:35
Query planner heuristic update: When doing a full table scan on a table that has an equality constraint on an unindexed column, do not allow the estimated number of output rows to be greater than half the total number of rows in the table. (check-in: 73954f93 user: drh tags: trunk)
2014-09-05

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)
2014-09-02
19:59
Add an experimental extension for applying bulk updates to databases. (check-in: 2954ab50 user: dan tags: ota-update)

2014-09-01
23:06

22:34
Avoid a confusing (though correct) argument to the sqlite3_result_blob() function in the implementation of ANALYZE. (check-in: 4cae93f8 user: drh tags: trunk)
19:29
For sqlite3_win32_is_nt(), assume WinRT is NT-based and revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. (check-in: be0a0372 user: mistachkin tags: trunk)
18:21

The SQLITE_MAX_WORKER_THREADS and SQLITE_DEFAULT_WORKER_THREADS compile-time options and the SQLITE_LIMIT_WORKER_THREADS argument to sqlite3_limit() and the "PRAGMA threads=N" pragma are added. (check-in: b1c0f0bc user: drh tags: trunk)
2014-08-29
19:06
Disable worker threads when SQLITE_THREADSAFE=0. Set the default compile-time maximum number of worker threads to 8 and honor the SQLITE_DEFAULT_WORKER_THREADS compile-time constant (which defaults to 0). (Closed-Leaf check-in: 33fa0410 user: drh tags: threads)
18:06
Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (check-in: 2ab4b5ad user: drh tags: threads)
16:20
Add SQLITE_LIMIT_WORKER_THREADS for controlling the maximum number of worker threads. (check-in: 1b598c68 user: drh tags: threads)

2014-08-25
23:44
Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. (check-in: e3305d4b user: drh tags: threads)
22:43
Merge the CAST operator enhancements from trunk. (check-in: 6c8f86e4 user: drh tags: threads)
