|
2013-02-23
| ||
| 16:40 | [0b8d2108a1] part of check-in [b73847f17b] If a rollback mode transaction reduces the size of the database file, avoid actually truncating the file until after the transaction has been committed (but before the db has been unlocked). This means pages that are removed from the database by truncating the file need not be journalled. (check-in: [b73847f17b] user: dan branch: incr-vacuum-opt, size: 26703) | |

|
2012-10-13
| ||
| 19:58 | [cab40f2c1f] part of check-in [af5c9ee4a4] Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients. (check-in: [af5c9ee4a4] user: dan branch: zero-byte-backup-fix, size: 25882) | |
|
2012-09-28
| ||
| 20:23 | [afc067b9a9] part of check-in [89b8c377a6] Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use. (check-in: [89b8c377a6] user: dan branch: trunk, size: 25659) | |

2012-06-21
| ||
| 15:51 | [5524df3681] part of check-in [fb8893abee] Add the sqlite3_close_v2() interface (from the deferred-close branch) that allows close operations to happen out-of-order in bindings to garbage-collected langauges. (check-in: [fb8893abee] user: drh branch: trunk, size: 25445) | |
|
2012-06-02
| ||
| 14:32 | [641eab30db] part of check-in [e276a02b7f] The sqlite3_close() interface returns SQLITE_OK even if there are outstanding sqlite3_stmt and sqlite3_backup objects. The connection becomes a zombie. Resource deallocation is deferred until the last sqlite3_stmt or sqlite3_backup object closes. This is intended to help SQLite play nicer with garbage collectors. (check-in: [e276a02b7f] user: drh branch: deferred-close, size: 25422) | |
|
2012-05-15
| ||
| 18:28 | [d7fb4c6d2a] part of check-in [aa0c3493d3] The former sqlite3ResetInternalSchema() routine was really two different routines, selected by parameter, each with a confused mission. So split this routine up into three separate smaller routines, calling each separately as needed. Hopefully this will make further refactoring and schema reset collateral damage containment easier. (check-in: [aa0c3493d3] user: drh branch: shared-schema, size: 25457) | |

Note: This causes separate shared-cache connections in read_uncommitted mode to abort as well. (check-in: [9b66c79e05] user: drh branch: nonblocking-rollback, size: 25453) | |

| 14:27 | [4368158da7] part of check-in [07159e84b4] If an error occurs while writing to the database file during a VACUUM, discard the contents of the in-memory cache.

Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others.
