2014-01-21
22:25
Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. check-in: b2671e11 user: drh tags: cte-via-queue
15:04
Remove the undocumented requirement for applications that use an SQLITE_ENABLE_SQLLOG build to define a sqlite3_init_sqllog() function. check-in: 5e43bf01 user: dan tags: trunk

Fix a couple comment typos and one overly long line. No functional changes. Closed-Leaf check-in: c57deced user: mistachkin tags: level-pseudocolumn
00:19
Add support for the LEVEL pseudo-column in the recursive part of a common table expression. LEVEL has the value of 1 on the first iteration and successively larger integer values of subsequent iterations. It cannot have a table qualifier.

2014-01-20
19:55
In where.c, do not allocate space in sqlite3_index_info structures for the internal WHERE clause "terms" generated to record column equivalencies. Fix for ticket [1a1a194d1e5f8]. check-in: 7d9e2218 user: dan tags: trunk

17:40
Resolve table names within CTEs in the context in which the CTE is declared, not the context in which it is used. check-in: a7323838 user: dan tags: trunk
16:19
Add tests that verify that keywords WITH, WITHOUT, and RECURSIVE can still be used as table and column names. check-in: 9ca18a01 user: drh tags: trunk
15:27
Fix a compiler warning in selectPopWith(). check-in: c8eb1163 user: drh tags: trunk

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

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

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
03:13
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. Closed-Leaf check-in: 4e4483b2 user: drh tags: buggy-lemon
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
2014-01-10
23:21

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

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
2014-01-03
16:03

2014-01-01
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
2013-12-24
12:04
Add -I. to the main.mk makefile for building sqlite3.o and speedtest1. check-in: cc72c5ae user: drh tags: trunk
2013-12-23

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

Allow any arbitrary expression as the filename in an ATTACH statement, including functions and subqueries. check-in: df70a1f3 user: drh tags: trunk
13:11
Simplify the accumulator reset for aggregate query processing so that it uses a single multi-register OP_Null rather than a separate OP_Null for each register. check-in: 2c7fd9b0 user: drh tags: trunk
2013-12-19
17:04

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

2013-12-18
18:44
Remove an unnecessary column-cache flush operation. Add code to trace the column cache when compiled with SQLITE_DEBUG and using PRAGMA vdbe_addoptrace=ON. check-in: 58704ed1 user: drh tags: trunk
16:27
Remove an unnecessary column-cache flush. Add another test case to the speedtest1.c program to accentuate the benefit of not flushing the cache at that point. Closed-Leaf check-in: 97fdfc6b user: drh tags: column-cache-debug
15:11
Show changes to the column cache when PRAGMA vdbe_addoptrace=ON is set. check-in: 4c6a659c user: drh tags: column-cache-debug

19:35
Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. check-in: e00f37e2 user: drh tags: trunk
18:50
Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. check-in: a845779c user: drh tags: trunk

Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests. check-in: fdc3f3fa user: dan tags: zipvfs-multifile-commit

Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. check-in: 4d078147 user: drh tags: trunk

Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. check-in: fbfc075a user: drh tags: trunk
03:07
Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). check-in: 2d6dd7c2 user: drh tags: trunk
02:32
Use memmove() rather than a home-made copy loop in insertCell() too. check-in: a3d796b1 user: drh tags: trunk
01:58
Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. check-in: 78e17068 user: drh tags: trunk
01:04
Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. check-in: 81f5ae13 user: drh tags: trunk

17:01
Increase the version number to 3.8.3. check-in: 23d00f22 user: drh tags: trunk
16:56
At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. check-in: 369a23e0 user: drh tags: trunk
16:45
Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. Closed-Leaf check-in: 9c59f5af user: drh tags: detect-moved-db
12:29
Actually look at i-node numbers to determine whether or not the database file has moved. check-in: 2b1884dc user: drh tags: detect-moved-db

Add the SQLITE_READONLY_DBMOVED error code to the sqlite3ErrName() function. check-in: 7789f801 user: mistachkin tags: detect-moved-db
17:23
Only error out on a database file move when attempting to start a write transaction. Assume read transactions are still safe. And make the error SQLITE_READONLY_DBMOVED instead of SQLITE_IOERR_NODB. check-in: 28348f2a user: drh tags: detect-moved-db
15:37
Add code to detect if the database file is moved or deleted out from under SQLite and return an SQLITE_IOERR_NODB. check-in: 8759a8e4 user: drh tags: detect-moved-db
