2017-09-09
| ||
| 08:03 | Use a mutex-free PRNG for the random() and randomblob() SQL functions and for the randomness used during checkpoint operations. file: [f27af409] check-in: [e63d1a7c] user: drh branch: mutex-free-randomness, size: 4591 | |
|
2016-12-07
| ||
| 15:49 | Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE. file: [80f5d666] check-in: [f3608187] user: drh branch: trunk, size: 3908 | |
|
2014-10-27
| ||
| 20:14 | Remove a small amount of unnecessary #ifdeffery from random.c. file: [ba2679f8] check-in: [2b9340c8] user: drh branch: trunk, size: 3922 | |
| 19:58 | Fix compilation issue with MSVC due to a misplaced variable declaration. file: [f88232b9] check-in: [9588b345] user: mistachkin branch: trunk, size: 3951 | |
|
2014-10-24
| ||
| 12:37 | Fix two problems. Tests now passing. file: [b8a05813] check-in: [1c220b80] user: drh branch: api-armor, size: 3883 | |
| 00:35 | Add the SQLITE_ENABLE_API_ARMOR compile-time option. This is a work in progress and is not yet completely functional. file: [689c95a5] check-in: [c297a84b] user: drh branch: api-armor, size: 3817 | |
|
2014-01-01
| ||
| 14:00 | Enhance sqlite3_randomness(N,P) such that it resets the internal PRNG if N is less than 1. Subsequent calls to sqlite3_randomness() will reinitialize the internal PRNG by calling the xRandomness() method of the default VFS. file: [d10c1f85] check-in: [a221aa82] user: drh branch: trunk, size: 3798 | |
|
2013-08-21
| ||
| 22:09 | Refactor the sqlite3_randomness() implementation for improved performance. file: [0b2dbc37] check-in: [4144dffb] user: drh branch: trunk, size: 3785 | |
|
2009-11-10

|
2008-12-10
| ||
| 19:26 | Never use strlen(). Use our own internal sqlite3Strlen30() which is guaranteed to never overflow an integer. Additional explicit casts to avoid nuisance warning messages. (CVS 6007) file: [676b9d7a] check-in: [c872d554] user: drh branch: trunk, size: 4730 | |
|
2008-12-08
| ||
| 18:19 | The amalgamation now compiles cleanly on GCC with options -pedantic-errors -Wno-long-long. (CVS 5991) file: [67bf41b2] check-in: [73c7302c] user: drh branch: trunk, size: 4727 | |
|
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: [a87afbd5] check-in: [02a12eb1] user: drh branch: trunk, size: 4745 | |
|
2008-09-02
| ||
| 00:52 | Continuing work on adding full support for the SQLITE_OMIT_WSD compile-time option. (CVS 5658) file: [11bbdf7d] check-in: [ef26ea5c] user: drh branch: trunk, size: 4749 | |
|
2008-06-19
| ||

|
2008-06-18
| ||
| 17:09 | Implement the 'CONFIG_SINGLETHREAD' and 'CONFIG_MULTITHREAD' configuration modes. (CVS 5234) file: [362b62e2] check-in: [5059644c] user: danielk1977 branch: trunk, size: 3978 | |
|
2008-03-21
| ||
| 16:45 | Add a completely new testing system for the Bitvec object. The new testing system uses sqlite3_test_control() instead of unpublished APIs. Now provides 100% condition/decision coverage. Obscure bugs in Bitvec found and fixed as a result of the enhanced coverage. (CVS 4902) file: [2b2db2de] check-in: [2498d3ea] user: drh branch: trunk, size: 4016 | |
|
2008-03-19
| ||
| 14:15 | Add a new api sqlite3_randomness() for providing access to SQLite's internal PRNG. Add sqlite3_test_control() verbs for controlling the PRNG. (CVS 4882) file: [8b6ab541] check-in: [15110ea0] user: drh branch: trunk, size: 4010 | |

| ||
| 13:51 | Remove the obsolete static mutexes. Use only the lastest static mutex code. (CVS 4259) file: [4a227465] check-in: [6225cd46] user: drh branch: trunk, size: 3218 | |
| 10:44 | Remove unnecessary #includes of "os.h". New mutex implementations. (CVS 4255) file: [89b2c5a9] check-in: [fbbd5bda] user: drh branch: trunk, size: 3168 | |
|
2007-08-20
| ||
| 22:48 | Work toward multithreading support. Currently crashes quickly on a test. (CVS 4253) file: [af7264b4] check-in: [1315bd8e] user: drh branch: trunk, size: 3184 | |
|
2007-08-17
| ||
| 15:53 | Begin migration to using sqlite3_vfs interface. (CVS 4240) file: [00b30565] check-in: [af3e3c7a] user: danielk1977 branch: trunk, size: 3192 | |

2006-01-06
| ||
| 14:32 | Change the OS interface layer to use traditional direct function call implementations instead of the more complicated virtual function table. Omit the asynchronous I/O demo. (CVS 2870) file: [d40f8d35] check-in: [2529c2e1] user: drh branch: trunk, size: 3078 | |
|
2005-11-30
| ||
| 03:20 | Restructure the OS interface yet again. This time make the OsFile object a virtual base class which is subclassed for unix, windows, and the crash test simulator. Add the new file "os.c" for common os layer code. Move all OS-specific routines into the sqlite3Os structure. (CVS 2795) file: [ff5e9a8c] check-in: [bd8740d1] user: drh branch: trunk, size: 3084 | |
|
2005-06-12
| ||
| 21:35 | Update older opcode names to be more meaningful in light of the latest code design. (CVS 2506) file: [90adff4e] check-in: [36f2da1f] user: drh branch: trunk, size: 3078 | |
|
2004-05-08
| ||
| 08:23 | Change lots of internal symbols from sqliteXXX to sqlite3XXX so that the library links again. It doesn't work yet, due to changes in the btree layer calling convention. (CVS 1324) file: [eff68e3f] check-in: [8af6474c] user: danielk1977 branch: trunk, size: 2945 | |

|
2002-01-16
| ||

|
2001-10-09
| ||

|
2001-09-23

|
2001-09-19

|
2001-09-16

|
2001-09-14
| ||
| 03:24 | All tests now pass. But there are still issues. For example, inserts are way too slow. And additional tests are needed for new features. (CVS 243) file: [b626726c] check-in: [e7b65e37] user: drh branch: trunk, size: 4160 | |
|
2001-09-13
| ||
| 21:53 | Many problems fixed. Many problems yet to go. (CVS 242) file: [55775802] check-in: [62c7bd11] user: drh branch: trunk, size: 3927 | |
|
2001-01-31
| ||
| 13:28 | Working better with Win95. Continued work on the new db.c backend. (CVS 1714) file: [b36c3f57] check-in: [df0ff304] user: drh branch: trunk, size: 3913 | |
