| 13:39 | [6d2f6727] part of check-in [7da617e9] Enhance the sqlite3_normalize_sql() interface so that it works even if the prepared statement was not initially compiled using SQLITE_PREPARE_NORMALIZED. Enhance the ".trace" command in the CLI so that it is able to access the full scope of functionality provided by sqlite3_trace_v2() and in particular so that it is able to show normalized SQL output using the newly enhanced sqlite3_normalize_sql() interface.

| ||
| 15:16 | [a3dc015f] part of check-in [17349a49] Changes to help ensure that a multiplication does not overflow when computing the number of bytes needed for a memory allocation, and cause a malfunction.

|
2014-01-24
| ||
| 16:36 | [d1393199] part of check-in [b1824344] Use an unsigned integer to accumulate the string hash. Avoids compiler warnings. (check-in: [b1824344] user: drh branch: trunk, size: 8171) | |

2009-05-09
| ||
| 23:29 | [ebcaa921] part of check-in [42372999] Convert an always-true condition in hash.c into an assert(). (CVS 6624) (check-in: [42372999] user: drh branch: trunk, size: 7912) | |

| 15:43 | [407e5ca1] part of check-in [5c737835] Simplifications to the symbol table implementation in hash.c.

|
2008-06-15
| ||

|
2008-05-13
| ||
| 13:27 | [fd8cb06f] part of check-in [a9d1d931] Make the benign-fault setting recursive. Make all malloc failures during a rollback benign since there is nothing we can do about them. (CVS 5128) (check-in: [a9d1d931] user: drh branch: trunk, size: 12884) | |
|
2008-04-02

|
2008-01-22
| ||
| 21:30 | [2dc6afe7] part of check-in [1a335e18] Add the fault injector module in fault.c. Use it as a basis for memory allocation failure testing. (CVS 4742) (check-in: [1a335e18] user: drh branch: trunk, size: 12796) | |

| 04:30 | [05ebefb8] part of check-in [deb7ecd6] Half-way through a major refactoring of the memory allocation. I have not even attempted to compile so I am certain there are countless errors. (CVS 4231) (check-in: [deb7ecd6] user: drh branch: trunk, size: 11916) | |
|
2007-03-31
| ||
| 03:59 | [67b23e14] part of check-in [2aae1964] Fix a long-standing memory leak in the hash table. The leak only appears following a malloc failure of a hash that copies its keys, which rarely happens and so we have not previously noticed it. (CVS 3777) (check-in: [2aae1964] user: drh branch: trunk, size: 11942) | |
|
2006-02-14
| ||

| ||
| 08:23 | [440c2f8c] part of check-in [8af6474c] Change lots of internal symbols from sqliteXXX to sqlite3XXX so that the library links again.
