Changes In Branch api-armor Excluding Merge-Ins
This is equivalent to a diff from 9762ad06 to 1c220b80
2014-10-27
| ||
18:34 | Add the SQLITE_ENABLE_API_ARMOR compile-time option for extra API parameter validation. Enhance sqlite3_stricmp(), sqlite3_strnicmp(), and sqlite3_uri_parameter() for improved NULL parameter handling. (check-in: ffb9d814 user: drh tags: trunk) | |
2014-10-24
| ||
14:32 | Get the likelihood() functions working on operators like BETWEEN that create virtual terms in the WHERE-clause analysis. (check-in: 03d0498d user: drh tags: trunk) | |
12:37 | Fix two problems. Tests now passing. (Closed-Leaf check-in: 1c220b80 user: drh tags: api-armor) | |
00:35 | Add the SQLITE_ENABLE_API_ARMOR compile-time option. This is a work in progress and is not yet completely functional. (check-in: c297a84b user: drh tags: api-armor) | |
2014-10-23
| ||
01:01 | Implement sqlite3_create_collation() by invoking sqlite3_create_collation_v2() with a NULL destructor argument. This saves a little space. (check-in: 9762ad06 user: drh tags: trunk) | |
2014-10-22
| ||
20:07 | Disable the use of strchrnul() unless specifically enabled by compile-time options. (check-in: e580470d user: drh tags: trunk) | |
