| 20:12 | Fix the sqlite3_trace_v2() interface so that it goes disabled if either the callback or mask arguments are zero, in accordance with the documentation. Cherrypick of [37e6c54b1afc6348]. check-in: e9acf616 user: mistachkin tags: branch-3.14 | |
| 19:47 | Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly. Cherrypick of [4d43c4698eef4e3d]. check-in: c844f3da user: mistachkin tags: branch-3.14 | |

| 17:27 | The previous commit could miss an SQLITE_NOMEM error. This commit catches it. Closed-Leaf check-in: 3a9f4750 user: dan tags: mistake | |
| 17:18 | Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. check-in: 7908fc60 user: dan tags: trunk | |
|
2016-09-01
| ||
| 14:03 | Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. check-in: f4ba894a user: dan tags: trunk | |
| 09:35 | If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed.

| 18:34 | Fixes to fts5 snippet() function. check-in: d464a7b1 user: dan tags: trunk | |
| 14:05 | Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly. These changes are already in the rowvalue branch but are added here since they are technically unrelated to rowvalue. check-in: 4d43c469 user: drh tags: trunk | |
|
2016-08-26

| 17:02 | Add a new method to sessions - sqlite3sessions_fullchangeset() - to return a changeset that always contains values for all old.* fields. Update changebatch to use these values to more reliably detect multi-column UNIQUE constraint violations. check-in: efa761b2 user: dan tags: changebatch | |
| 14:42 | Fix the SQLITE_USER_AUTHENTICATION login check so that the SQLITE_AUTH_USER error code correctly propagates and is not overwritten by SQLITE_ERROR. check-in: c640489d user: drh tags: trunk | |
|
2016-08-22
| ||
| 21:01 | Add a couple of extra tests to changebatch1.test. check-in: 207d970b user: dan tags: changebatch | |

| 14:25 | Have the fts5 snippet() function avoid favouring snippets that begin with sentences that do not contain search terms. Add an extra bias in favour of the first sentence in the document. check-in: d8180af2 user: dan tags: fts5-snippet-bias | |
| 14:20 | Add the capability to VACUUM an attached database by specifying the schema name as an argument to the VACUUM command. Since version 2.0, VACUUM has accepted an argument which was silently ignored. Now it has meaning. check-in: 29d63059 user: drh tags: vacuum-attached-db | |

|
2016-08-16
| ||
| 16:46 | Fix a bug in destructor processing of Lemon. That has no impact on the SQLite grammar. The bug was introduced by prior work to optimize the Lemon-generated parser used by SQLite. check-in: f9035b8e user: drh tags: trunk | |

| 12:35 | Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. When enabled, the "unknown function" error is suppressed for EXPLAIN and a no-op function named "unknown()" is substituted.
