| 16:02 | Consolidate the two sqlite3SchemaToIndex() routines. file: [786ad531] check-in: [dfab7170] user: dan branch: reuse-schema1, size: 9395 | |
|
2018-11-17
| ||
| 18:11 | Fix further problems with the feature on this branch. file: [aeee7f04] check-in: [6d7a7e5f] user: dan branch: reuse-schema1, size: 9396 | |
|
2018-04-25
| ||
| 12:01 | Avoid many unnecessary calls to sqlite3ReadSchema() and sqlite3Init() when the schema is known to be valid already. file: [8acc2f46] check-in: [58cf812f] user: drh branch: trunk, size: 9320 | |
|
2017-01-02
| ||
| 18:19 | Avoid unnecessary calls to sqlite3BtreeEnterAll() and sqlite3BtreeLeaveAll() when no btree is using shared-cache. file: [0e9ce2d5] check-in: [cfb31582] user: drh branch: trunk, size: 9323 | |
|
2016-01-07
| ||
| 16:06 | Have the vdbe layer call sqlite3BtreeEnter() on all b-trees in use from within sqlite3VdbeExec() even in SQLITE_THREADSAFE=0 builds. This ensures that BtShared.db is set correctly. file: [bc87dd3b] check-in: [d0214602] user: dan branch: shared-cache-fix, size: 9014 | |
|
2015-03-19
| ||
| 15:04 | Add an assert() to check that the database mutex is held in sqlite3BtreeLeave(). file: [45a968cc] check-in: [31f54d7b] user: dan branch: trunk, size: 9047 | |
|
2014-09-06
| ||
| 16:39 | Fix typos in comments. No code changes. file: [49ca6625] check-in: [e62aab5e] user: peter.d.reid branch: trunk, size: 9001 | |
|
2014-08-22
| ||
| 21:58 | Performance enhancements in the b-tree mutex logic. file: [ec9d3f12] check-in: [89145306] user: drh branch: trunk, size: 9002 | |
|
2011-04-06
| ||
| 22:05 | Fix a performance regression: Keep two btree masks in each prepared statement; one for btrees used and another for btrees that require locks. Only try to lock the btrees identified by the second mask. file: [976f45a1] check-in: [614de91a] user: drh branch: trunk, size: 8531 | |
|
2011-04-05
| ||
| 19:27 | Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. file: [7907af20] check-in: [51039b35] user: drh branch: trunk, size: 8339 | |
| 17:31 | Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. file: [1f951523] check-in: [242ce7cf] user: drh branch: trunk, size: 9128 | |
|
2011-04-04
| ||
| 18:22 | Add a description of access rules for the Schema object and lots of asserts to verify that the access rules are followed. file: [b8106222] check-in: [ae8374af] user: drh branch: schema-parse-refactor, size: 10166 | |
| 00:14 | Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. file: [3e595ee1] check-in: [d81708f7] user: drh branch: trunk, size: 9439 | |
|
2011-04-03

|
2009-11-10
| ||
| 01:30 | Remove the obsolete "$Id:$" RCS identifier strings from the source code. file: [96a12f50] check-in: [f6c045f6] user: drh branch: trunk, size: 10471 | |
|
2009-07-20
| ||
| 12:33 | Use an ALWAYS() on a conditional in btmutex.c that is always true. (CVS 6910) file: [0f43a75b] check-in: [609022ca] user: drh branch: trunk, size: 10529 | |
|
2009-07-17
| ||
| 11:44 | Code simplifications in support of structural testing. (CVS 6900) file: [f7b059a9] check-in: [fb1b955d] user: drh branch: trunk, size: 10366 | |
|
2009-04-10
| ||
| 12:55 | Changes to ensure that when running in shared-cache mode with a non-threadsafe build, the correct busy-handler callback is always invoked. (CVS 6481) file: [9b899c0d] check-in: [683e4bd7] user: danielk1977 branch: trunk, size: 10275 | |
| 09:47 | Always set BtShared.db when entering the BtShared mutex. Ticket #3793. (CVS 6480) file: [527b63e2] check-in: [ed6620ba] user: danielk1977 branch: trunk, size: 10040 | |
|
2009-03-05
| ||
| 04:20 | Corrected typos and misspellings. Ticket #3702. (CVS 6336) file: [341502bc] check-in: [6404afa0] user: shane branch: trunk, size: 9248 | |

2008-11-17
| ||
| 19:18 | Modifications to avoid unsigned/signed comparisons in various files. (CVS 5914) file: [63c5cc4a] check-in: [8009220c] user: danielk1977 branch: trunk, size: 9254 | |
|
2008-10-07
| ||
| 15:25 | Remove the SQLITE_MUTEX_APPDEF compile-time option. The SQLITE_THREADSAFE=0 option always removes all mutex code. For application-defined mutexes only, use SQLITE_THREADSAFE=1 with SQLITE_MUTEX_NOOP=1. Ticket #3421. (CVS 5779) file: [3a90096c] check-in: [02a12eb1] user: drh branch: trunk, size: 9269 | |
|
2008-07-14
| ||
| 19:39 | Add a new test script to exercise the deadlock avoidance code in the btree mutex logic. (CVS 5412) file: [709cad2c] check-in: [7d5e1c43] user: drh branch: trunk, size: 9326 | |
|
2008-01-23
| ||
| 12:52 | Improvements to test coverage in the lemon-generated parser and in the sqlite3_get_table() interface. (CVS 4745) file: [483ced3c] check-in: [9f95d79d] user: drh branch: trunk, size: 9350 | |
|
2007-12-07
| ||
| 18:55 | In shared-cache mode, make sure the busy hander invoked is the busy handler associated with the database connection that caused the lock contention in the first place. (CVS 4598) file: [5d39da37] check-in: [c9eb6591] user: drh branch: trunk, size: 9293 | |
|
2007-08-30

|
2007-08-29
| ||
| 17:43 | Improvements to mutex asserts. The quick test runs to completion without assertion faults. (CVS 4324) file: [abc2eda0] check-in: [2732af0e] user: drh branch: trunk, size: 9315 | |
| 04:00 | Better asserts(). But now some of the tests are busted again. (CVS 4320) file: [c04e67d9] check-in: [e8060f85] user: drh branch: trunk, size: 8835 | |
| 00:33 | More locking fixes. Now makes it all the way through quick.test. There are errors but no assertion faults. Progress. (CVS 4319) file: [0abcf98b] check-in: [844d40b8] user: drh branch: trunk, size: 7832 | |
|
2007-08-28

| 23:28 | The shared_err test runs with no errors. But a potential deadlock has been discovered and is still unfixed. (CVS 4317) file: [fc9d8316] check-in: [f84550be] user: drh branch: trunk, size: 6248 | |
| 16:44 | Fix locking bug in btshared.c. (CVS 4313) file: [3a19fcb3] check-in: [af24e7d0] user: drh branch: trunk, size: 6230 | |
| 02:27 | Work toward correct btree locking in a multithreaded environment. (CVS 4307) file: [e11c59a7] check-in: [b8cc493b] user: drh branch: trunk, size: 6171 Added | |
