16:18 | Fix ALTER TABLE RENAME COLUMN in cases where the column being renamed is an IPK declared with a separate PRIMARY KEY clause - "CREATE TABLE x(y INTEGER, PRIMARY KEY(y))". (check-in: 32ca8418 user: dan tags: alter-table-rename-column) | |
2018-08-13
| ||
22:50 | Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. (check-in: e3ea43da user: drh tags: trunk) | |
20:46 | Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. (check-in: 8b1e0010 user: drh tags: trunk) | |
17:14 | Edit the WHEN and UPDATE OF clauses of trigger programs as part of ALTER TABLE RENAME COLUMN. (check-in: 5fdb6b0a user: dan tags: edit-trigger-wrapper) | |
17:02 | Make the sqlite_rename_column() SQL function resistant to problems caused by OOMs and/or malformed parameters submitted by hostile application code. Also add additional comments to the RENAME COLUMN logic. (check-in: 87743dde user: drh tags: alter-table-rename-column) | |
15:09 | Fix legacy comments on Token. Begin commenting the new ALTER TABLE RENAME COLUMN code. Fix a memory leak in the sqlite_rename_column() SQL function. (check-in: 32edc892 user: drh tags: alter-table-rename-column) | |
13:43 | Fix issues with ALTER TABLE RENAME COLUMN associated with OOM errors. (check-in: 0b28dd5c user: drh tags: alter-table-rename-column) | |
12:58 | Fix a heap-corruption causing race condition in os_unix.c that could occur when one thread wal opening a database file while another is unlocking the same file. Edit: Let's go in a slightly different direction with this fix. (Closed-Leaf check-in: 2447e0fd user: dan tags: unix-lock-fix-attempt) | |
11:32 | Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. (check-in: 90f7c193 user: drh tags: trunk) | |
2018-08-11
| ||
20:46 | Add the "atrc" test program. "Atrc" is short for "ALTER TABLE RENAME COLUMN". See the header comment on the program itself for further information. (check-in: ed64a55a user: drh tags: alter-table-rename-column) | |
20:38 | If the new column name in an ALTER TABLE RENAME COLUMN statement is quoted, then also use quotes for the column name in the edited SQL statements. (check-in: ca5184a2 user: dan tags: alter-table-rename-column) | |
18:34 | Avoid an assert() sometimes triggered by ALTER TABLE RENAME COLUMN in non-debug builds. (check-in: 520c1c75 user: dan tags: alter-table-rename-column) | |
17:49 | Fix a bug causing ALTER TABLE RENAME COLUMN to fail when renaming an IPK column that is used in a CHECK constraint. (check-in: 6595c881 user: dan tags: alter-table-rename-column) | |
17:34 | Fix a bug causing all ALTER TABLE RENAME COLUMN commands to fail if ANALYZE had been run on the database. Also prevent the user from renaming the columns of system tables. (check-in: ca644a28 user: dan tags: alter-table-rename-column) | |
13:40 | Reload the entire schema after renaming a column in order to ensure that the schema for any tables for which parent key definitions were changed are reloaded. (check-in: f4497b01 user: dan tags: alter-table-rename-column) | |
2018-08-10
| ||
20:19 | Ensure the schema cookie is changed when a column is renamed. (check-in: 2dec9ea4 user: dan tags: alter-table-rename-column) | |
19:33 | Fix harmless compiler warnings. (check-in: 9564d700 user: drh tags: alter-table-rename-column) | |
19:19 | When a column is renamed, update any references to it in REFERENCES clauses that belong to other tables. (check-in: 191079bd user: dan tags: alter-table-rename-column) | |
15:27 | Merge latest trunk changes with this branch. (check-in: c355a837 user: dan tags: alter-table-rename-column) | |
14:23 | Fix a problem with renaming columns on tables with REFERENCES clauses that specify a large number of columns. (check-in: d48f7bbd user: dan tags: alter-table-rename-column) | |
2018-08-09
| ||
21:45 | Fix the isLikeOrGlob() routine in the WHERE clause processing logic so that it avoids signed/unsigned character comparisons, as that can lead to an incorrect answer if the ESCAPE clause is an invalid UTF8 string. Problem found by OSSFuzz. (check-in: 4195a3f8 user: drh tags: trunk) | |
20:47 | Experimental implementation of ALTER TABLE ... RENAME COLUMN. Still buggy. (check-in: fa0fc01e user: dan tags: alter-table-rename-column) | |
18:36 | When a column must be a constant due to WHERE clause and the value of that column is being coded as a constant, make sure the affinity is correct. (check-in: 7404ea83 user: drh tags: trunk) | |
2018-08-08
| ||
20:46 | Minor style improvements. (check-in: 60bbca2b user: mistachkin tags: trunk) | |
2018-08-06
| ||
17:12 | Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. (Closed-Leaf check-in: 051ac015 user: dan tags: exp-snapshot-open) | |
02:08 | Enhance the edit() function so that it converts text from \r\n back into \n only if the original unedited copy contained no \r\n values. (check-in: 20c995d3 user: drh tags: trunk) | |
01:39 | Add the --info option to the fuzzcheck test utility. (check-in: 1caaaaa7 user: drh tags: trunk) | |
01:21 | Fix an overzealous assert() statement discovered by OSSFuzz. (check-in: d9c9fe9f user: drh tags: trunk) | |

20:30 | Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7 user: drh tags: trunk) | |
20:12 | Remove a testcase() that is no longer reachable without the column cache. Provide an assert() to help prove that the testcase is no longer reachable. (Closed-Leaf check-in: a500893b user: drh tags: omit-column-cache) | |
17:15 | Fix comments that were made obsolete by the removal of the column cache. (check-in: 2041231d user: drh tags: omit-column-cache) | |
16:54 | Remove more column-cache residue: The OP_SetColTab and OP_VerifyColTab opcodes and the associated SQLITE_DEBUG_COLUMNCACHE logic. (check-in: 80236e81 user: drh tags: omit-column-cache) | |
