Ensure that CREATE VIEW, TRIGGER or INDEX statements can be edited by ALTER TABLE RENAME COLUMN even if they use collation-sequences or user-defined-functions that are not available. check-in: 540014efd6 user: dan tags: edit-trigger-wrapper
2018-08-16
19:49
Further progress on updating trigger programs as part of ALTER TABLE RENAME COLUMN. check-in: 3f47222b6e user: dan tags: edit-trigger-wrapper

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: 32ca8418df user: dan tags: alter-table-rename-column
15:12
Fix UPSERT so that it checks the target-constraint first and fires the DO UPDATE if that constraint is violated regardless of whether or not other constraints are in violation. This aligns SQLite behavior with what PostgreSQL does. Fix for ticket [908f001483982c43cdb476dfb590a1a]. check-in: 529fb55e3d user: drh tags: trunk
2018-08-13
22:50
Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. check-in: e3ea43dabf user: drh tags: trunk
20:46
Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. check-in: 8b1e0010b9 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: 5fdb6b0aaf 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: 87743ddef1 user: drh tags: alter-table-rename-column
15:09

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: ed64a55a22 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: ca5184a25f 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: 520c1c75da 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: 6595c8811f 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: ca644a2877 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: f4497b0136 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: 2dec9ea4ab user: dan tags: alter-table-rename-column
19:33
Fix harmless compiler warnings. check-in: 9564d7008c 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: 191079bd4f user: dan tags: alter-table-rename-column
15:27
Merge latest trunk changes with this branch. check-in: c355a83707 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: d48f7bbdf4 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: 4195a3f8b5 user: drh tags: trunk
20:47
Experimental implementation of ALTER TABLE ... RENAME COLUMN. Still buggy. check-in: fa0fc01eb4 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: 7404ea8316 user: drh tags: trunk
2018-08-08
20:46
Minor style improvements. check-in: 60bbca2b9a user: mistachkin tags: trunk
2018-08-06
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: 20c995d3f0 user: drh tags: trunk
01:39
Add the --info option to the fuzzcheck test utility. check-in: 1caaaaa70f user: drh tags: trunk
01:21
Fix an overzealous assert() statement discovered by OSSFuzz. check-in: d9c9fe9f5a user: drh tags: trunk
2018-08-04
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: cdff3af7be 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: a500893b6f user: drh tags: omit-column-cache
17:15
Fix comments that were made obsolete by the removal of the column cache. check-in: 2041231d56 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: 80236e81ce user: drh tags: omit-column-cache
15:53
Further logic simplifications that flow out of the omission of the column cache. check-in: 7d9072b027 user: drh tags: omit-column-cache
15:28
Add test cases for the constant expression fix of the previous check-in. check-in: 95db5bd9fe user: drh tags: trunk
15:16
Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. check-in: 8bc7f84c39 user: drh tags: trunk
14:30
Remove additional traces of the column cache. check-in: db6052e972 user: drh tags: omit-column-cache
2018-08-03
23:04
Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. check-in: 3f5f60cd75 user: drh tags: omit-column-cache
20:19
Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. check-in: 21235d9a41 user: dan tags: trunk
15:58
Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. check-in: fa94b49e02 user: drh tags: trunk
13:56
Improve "PRAGMA vdbe_trace=ON" to always show the key values for the OP_IdxGT and related opcodes. check-in: 0f881955ed user: drh tags: trunk
2018-07-29
18:56
In the command-line shell, always exit if realloc() fails. check-in: e390023c8e user: drh tags: trunk
