| 22:40 | Add the ability for the authorizer callback to disallow recursive queries. check-in: 9efc120a user: drh tags: common-table-expr | |
| 21:59 | Tweaks to error message text. check-in: 090a77d9 user: drh tags: common-table-expr | |
| 21:02 | Improve the error messages used to report illegal recursive cte references. check-in: 54eee9fe user: dan tags: common-table-expr | |
| 18:34 | Allow only a single recursive reference in a recursive CTE. Also require that this reference is not part of a sub-query. check-in: a296b733 user: dan tags: common-table-expr | |
| 15:31 | Always use available indices to optimize LIKE operators even if the pattern of the LIKE operator has a COLLATE modifier. This fixes an ineffiency that was introduced into 3.7.15 by check-in [8542e6180d4] on 2012-12-08. check-in: 16bd5478 user: drh tags: trunk | |
| 10:58 | Disable the flattening optimization if the parent query is the recursive part of a recursive CTE and the sub-query is a compound query. check-in: 6bfa387e user: dan tags: common-table-expr | |
| 04:37 | Merge trunk changes. Fix a possible NULL-pointer deference in WITH clause name resolution. check-in: 7f953b56 user: drh tags: common-table-expr | |

| 20:10 | Remove an ALWAYS() that is no longer always true. check-in: c95823cd user: drh tags: common-table-expr | |
| 19:42 | Fixes so that SQLITE_OMIT_CTE builds work. check-in: 3908e2ea user: dan tags: common-table-expr | |
| 18:35 | Further comments on WITH-clause processing routines in select.c. check-in: c948384d user: drh tags: common-table-expr | |
| 18:23 | Add a header comment to the searchWith() routine. check-in: d9ae0f5d user: drh tags: common-table-expr | |
| 18:21 | Disable automatic indices on recursive CTE references. check-in: 28aa6db8 user: dan tags: common-table-expr | |
| 18:12 | When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context. This ensures that correlated sub-queries are correctly identified as such. check-in: 61be2da0 user: dan tags: common-table-expr | |
| 15:27 | Return an error if a CTE specifies a different number of columns than its SELECT statement returns. check-in: 9a514b50 user: dan tags: common-table-expr | |
| 14:40 | Don't try to verify the schema of transient table (such as generated inside a WITH clause) when generating code for "IN table" operators. check-in: 860aa936 user: drh tags: common-table-expr | |
| 14:17 | Disable the flattening optimization if the sub-query is a recursive CTE. check-in: 9472f6d8 user: dan tags: common-table-expr | |
| 02:40 | Use the user-supplied table name in WITH RECURSIVE tables as the internal name of the table and the name of the table in VDBE comments. check-in: a2933023 user: drh tags: common-table-expr | |

| 20:38 | In the command-line shell, defend against a NULL-pointer dereference in the case where sqlite3_column_name() returns NULL (as might happen following an OOM error). check-in: ac15455a user: drh tags: trunk | |
| 20:32 | For statements of just an unadorned VALUES clause, assign column names as "columnN" for increasing whole numbers N. check-in: 260587d2 user: drh tags: trunk | |
| 16:36 | Fix some memory leaks and crashes that could follow an OOM condition during WITH clause parsing. check-in: 8839850c user: dan tags: common-table-expr | |
| 15:12 | Add code to handle non-recursive CTEs in the same way as SQL views. check-in: a26f399b user: dan tags: common-table-expr | |

| 19:19 | Update the parser so that sub-queries and CTEs may have WITH clauses. check-in: 704d3931 user: dan tags: common-table-expr | |
| 13:22 | Parse common table expressions. But do not do anything with them (yet). check-in: da98b720 user: drh tags: common-table-expr | |
| 12:52 | In LEMON, limit the size of the grammar file to 100MB. This ensures that the program will never experience integer overflow. To be doubly sure, use calloc() instead of malloc() when allocating arrays. check-in: 29ba458d user: drh tags: trunk | |
| 03:54 | Optimizations to the SQL language grammar that result in a small size reduction and speed increase. check-in: cb5d1f83 user: drh tags: trunk | |
| 03:27 | Add the "%token_class" directive to the LEMON parser generator. This opens up the possibility of simplifying the parser. Also remove all calls to sprintf(), strcpy(), and strcat() from LEMON to avoid compiler warnings on OpenBSD. (Aside: It is this change to avoid harmless compiler warnings that was the cause of the reason spat of bugs.) check-in: 8eb48c04 user: drh tags: trunk | |
| 03:06 | In LEMON, fix a bug in the text formatter introduced by the previous commit. Also add the new "%token_class" directive for defining symbolic names that stand any one of a collection of tokens. Closed-Leaf check-in: da7890ca user: drh tags: lemon-updates | |

| 20:00 | Fix an typo that breaks the build when SQLITE_ENABLE_TREE_EXPLAIN is defined. check-in: f461e2b3 user: drh tags: trunk | |
| 19:58 | Add the usual "fts3" prefix to new static method setEstimatedRows() in fts3.c. This fixes a problem when compiling the amalgamation, as the r-tree module also contains a static method named setEstimatedRows. check-in: d6fcfc88 user: dan tags: trunk | |
| 19:27 | Avoid redundant register loads during index key generation when doing a DELETE or INTEGRITY_CHECK on a table with multiple indices. check-in: 8f6e6149 user: drh tags: trunk | |
| 16:49 | Omit OP_Close operations that occur immediately prior to OP_Halt and which cannot be jumped over. check-in: 874b7e99 user: drh tags: trunk | |
| 15:17 | Improvements to the column-cache for nested AND/OR operators. check-in: 4e725f53 user: drh tags: trunk | |
| 14:46 | Have FTS assign extremely high costs to plans that feature unusable MATCH constraints. This discourages the planner from choosing such plans, which lead to "unable to use function MATCH in the requested context" errors. check-in: fa8be488 user: dan tags: trunk | |
| 14:42 | Instead of having the planner ignore plans with unusable MATCH constraints, have FTS assign extremely high costs to such plans in order to discourage the planner from using them. Closed-Leaf check-in: 24f84b38 user: dan tags: avoid-unusable-match | |
| 14:16 | Have the planner detect cases where a MATCH constraint is applied to a virtual table, and ignore any plans that do not allow the virtual table implementation to implement the MATCH filtering. check-in: 19f3208b user: dan tags: avoid-unusable-match | |

| 15:18 | Try to detect process ID changes due to fork() calls in os_unix.c and reset the PRNG when a process ID change is detected. check-in: e1eba1fb user: drh tags: trunk | |
| 14:00 | Enhance sqlite3_randomness(N,P) such that it resets the internal PRNG if N is less than 1. Subsequent calls to sqlite3_randomness() will reinitialize the internal PRNG by calling the xRandomness() method of the default VFS. check-in: a221aa82 user: drh tags: trunk | |

| 17:14 | Fix speedtest1.c so that in --explain mode it only outputs non-explain text for DDL statements. check-in: 2d2b3c49 user: drh tags: trunk | |
| 17:07 | Avoid compiler warnings by only enabling sqlite3ErrName() when SQLITE_TEST is defined. check-in: 862228e5 user: drh tags: trunk | |
| 16:06 | Fix harmless compiler warnings in FTS4. This involved corrupting Martin Porter's beautifully written and elegant stemmer code, making it a little less beautiful and a little less elegant. Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. check-in: df056798 user: drh tags: trunk | |
| 15:46 | Fix the ".echo on" dot-command of the shell so that it echos comments in addition to SQL statements and dot-commands. Add the --explain option to speedtest1 so that the output can be piped into the command-line shell to show nicely-formated VDBE code for the entire test. check-in: 96397263 user: drh tags: trunk | |
| 00:04 | Add a case to speedtest1.c that demonstrates the need to factor OP_Column operators out of inner loops. check-in: 69a17336 user: drh tags: trunk | |

| 17:04 | Do not inject OOM faults into SQLITE_FCNTL_COMMIT_PHASE_TWO file-control invocations. It causes problems for test scripts. check-in: 8eb28d23 user: dan tags: trunk | |
| 16:26 | Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. check-in: ca3fdfd4 user: drh tags: trunk | |
| 14:34 | Remove an unneeded column-cache flush in aggregate SELECT and an unreachable branch in the INSERT logic. check-in: ffa092e1 user: drh tags: trunk | |
