54 check-ins using file ext/misc/regexp.c version c1fb4f06

2022-07-16
18:08
Fixes for the generated "mallocs.tcl" and "leaks.tcl" scripts generated by running tcl tests with the --malloctrace=1 option. (check-in: 449799e2 user: dan tags: trunk)
2022-07-15
20:39
In the query planner, restore the former aggressiveness in reordering of FROM clause terms that existed prior to version 3.39.0 for queries that contain no RIGHT or FULL JOINs. (check-in: 92d60b64 user: drh tags: trunk)
15:08
Fix a memory leak in fts3 that could occur when processing a corrupt database. (check-in: d74f6f6d user: dan tags: trunk)
12:16
Fix the whereKeyStats() routine (part of STAT4 processing only) so that it is able to cope with row-value comparisons against the primary key index of a WITHOUT ROWID table. Forum post 3607259d3c. (check-in: 0620e419 user: drh tags: trunk)
11:34
Update some faulty assert() statements in fts3. (check-in: b072851b user: dan tags: trunk)
2022-07-14
21:17
Ensure all testrunner.tcl processes use the same pending-byte value when accessing testrunner.db. Otherwise locking doesn't work and the db is corrupted. (check-in: b6522565 user: dan tags: trunk)
18:09
Update testrunner.tcl so that it can run the test suites defined in permutation.test. (check-in: 15ce937e user: dan tags: trunk)
01:48
When applying the omit-ORDER-BY optimization, defer deleting the AST of the deleted ORDER BY clause until after code generation ends. (check-in: f22f95b8 user: drh tags: trunk)
2022-07-13
21:28
Fix testrunner.tcl so that it can detect the number of logical cores on osx. (check-in: 14918f28 user: dan tags: trunk)
21:10
Minor change to help message in testrunner.tcl. (check-in: e4f9cb01 user: dan tags: trunk)
21:02
Add new script test/testrunner.tcl. For running a set of test scripts using multiple processes. (check-in: 0122e93d user: dan tags: trunk)
20:26
Fix a problem preventing "testrunnter.tcl all" from working. (Leaf check-in: 0ed1e83c user: dan tags: testrunner)
19:57
Update testrunner.tcl to allow the user to specify which tests to run on the command line. (check-in: 900febcf user: dan tags: testrunner)
17:46
Fix testrunner.tcl so that it checks for memory leaks. (check-in: 106f6724 user: dan tags: testrunner)
15:52
The query flattener should not run if the subquery is a compound that contains a RIGHT JOIN in any arm and the subquery is not the first element of the outer query. Otherwise, prior elements of the outer query will not have the JT_LTORJ flag set. Fix for the problem reported in forum post 174afeae5734d42d. (check-in: 274e244c user: drh tags: trunk)
2022-07-12
20:31
Add test/testrunner.tcl, an experimental script for distributing the work of veryquick.test between multiple processes. (check-in: ef229cbb user: dan tags: testrunner)
15:53
Renamed the SQLITE_SHELL_WASM_WEB_MODE to SQLITE_SHELL_FIDDLE, which seems to be more in line with project convensions and indicates that that flag is only intended for /fiddle mode, as opposed to arbitrary wasm-on-the-web use. (check-in: d1d019bf user: stephan tags: trunk)
15:17
Fix another test case error message similar to those fixed in [b3d6b3c3]. (check-in: 6d0f6772 user: dan tags: trunk)
15:10
Update makefiles to fix building the non-amalgamation testfixture with SQLITE_DEBUG. (check-in: d9c4a9d0 user: dan tags: trunk)
10:46
Fix a bug in wapptest.tcl introduced by [51255bad4c1fb607]. (check-in: b26d097e user: drh tags: trunk)
09:40
Renamed SQLITE_SHELL_WASM_MODE to SQLITE_SHELL_WASM_WEB_MODE and no longer automatically enable it if __EMSCRIPTEN__ is defined, in order to facilitate using Emscripten to build the shell for CLI-based WASM runtimes (which cannot make use of the web-specific user input changes). The fiddle build now explicitly passes the new flag on at compile-time. (check-in: ee059ad5 user: stephan tags: trunk)
07:13
Back out the pager performance enhancement at [a1c090e08139f99d3], because it turns out we should never allow a zero key into the pcache interface according to the design specs, even if that page is immediately released without ever being used. (check-in: ec96293e user: drh tags: trunk)
2022-07-11
22:20
Add the --config option to wapptest.tcl. The argument is a glob pattern. All configurations must match the glob pattern in order to run. The default value is "*". (check-in: 51255bad user: drh tags: trunk)
21:40
Update the expected error messages in some OOM test cases to account for [44d77a7f807]. (check-in: b3d6b3c3 user: dan tags: trunk)
19:47
Use 64-bit memory allocation APIs in the sqlite_stmt virtual table, to avoid harmless compiler warnings. (check-in: afb9e60e user: drh tags: trunk)
19:12
In the sqlite_stmt extension, store the result of strlen() in a 64-bit integer to avoid a compiler warning, even though we know that the length will always fit comfortably in 32 bits. (check-in: 3fe19452 user: drh tags: trunk)
18:26
Fix harmless compiler warnings about unused debugging functions in treeview.c. (check-in: 4d6f9077 user: drh tags: trunk)
18:11
Back out the optimization at [1a8c2e54375ee2cf7] because there are some cases where it does not work. (check-in: fe39c8d5 user: drh tags: trunk)
14:36
Ensure that the Parse.nErr flag is set following an SQLITE_TOOBIG error on a nested parse. Fix for the problem identified by forum post d5a82ba9eedee30c. Also, remove unnecessary clearing of the Parse.zErrMsg field following a nested parse. (check-in: 44d77a7f user: drh tags: trunk)
14:26
Fix a problem in fts3 to do with deferred tokens and OR expressions. (check-in: d0bfe5c5 user: dan tags: trunk)
2022-07-10
21:12
When an OOM occurs and sets the Parse.nErr value, also set the Parse.nErr value for all outer Parse objects. dbsqlfuzz d33f60aaa67733aa700cd69dacf8e0e23a327a29 (check-in: 9a494d25 user: drh tags: trunk)
2022-07-08
20:03
Performance optimizations in the WHERE clause processing of the query planner. (check-in: 50c8e8de user: drh tags: trunk)
18:23
Omit an unnecessary structure initialization in whereLoopAddAll(), replacing it with an assert() to show that the initialization has already occurred, for a small performance increase and size reduction. (check-in: 27be9e96 user: drh tags: trunk)
17:57
Size reduction and performance optimization in whereLoopAddBtreeIndex(). (check-in: 64d2312c user: drh tags: trunk)
16:56
In wherePathSolver(), defer initializing variables until they are actually needed, in case they are not needed. This gives a small performance increase. (check-in: 6f28a965 user: drh tags: trunk)
15:06
Upgrade the TEA build system used to build the Tcl package. (check-in: ace65da8 user: dan tags: trunk)

Upgrade the TEA build system in autoconf/tea/. To match tclconfig commit 20fe9e6f59 and Tcl Sample Extension be47fb0446. (check-in: 1531f739 user: dan tags: tea-upgrade)
20:29
Size reduction and performance increase in the pageFindSlot() routine of btree.c. (check-in: 5d247e38 user: drh tags: trunk)
20:11
Size reduction and performance increase in the freeSpace() routine of btree.c. (check-in: 7d7aed05 user: drh tags: trunk)
2022-07-06
23:50

15:44
Avoid ignoring the last line of a csv file if the final field is empty and there is no trailing CFLS. Also have the csv extension treat the last line of a file in the same way as any other line if it is short fields. (check-in: 587795d4 user: dan tags: trunk)
13:59
Avoid dropping error codes in the xBegin() method of virtual table sqlite_dbpage. (check-in: 570e2bce user: dan tags: trunk)

10:40
Fix an assert() in btree to be more precise, as the previous form of that asser might fail due to recent performance optimizations. (check-in: 47749381 user: drh tags: trunk)
2022-07-04
15:14
Size reduction and performance optimization in sqlite3WalFindFrame(). (check-in: 1a8c2e54 user: drh tags: trunk)
09:41
