83 check-ins using file src/os_win.c version 1b21af72c5

2014-06-17
15:13
Small tweaks to the query planner to get it to try harder to use an index for sorting and to avoid using automatic indexes on constant terms. (Leaf check-in: 2d9de154f8 user: drh tags: branch-3.8.3)
2014-02-11
14:52
Version 3.8.3.1 (check-in: ea3317a480 user: drh tags: release, version-3.8.3.1, branch-3.8.3)
03:55
Increase the version number to 3.8.3.1. (check-in: 3111df71b2 user: drh tags: branch-3.8.3)
03:50
Make sure that virtual WHERE-clause terms do not get transformed into real terms when processing set of OR-connected terms. Fix for ticket [4c86b126f22ad]. (check-in: de635e0960 user: drh tags: branch-3.8.3)
2014-02-08
13:22

2014-02-04
23:45
Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. (check-in: f2504089df user: drh tags: trunk)
20:46
Remove the SF_Materialize flag from the SELECT object as it does not accomplish anything useful. (check-in: 65d5dcddbd user: drh tags: trunk)

Do not run test script mmapfault.test as part of the "inmemory_journal" permutation test. (check-in: b222b61a98 user: dan tags: trunk)
11:12
Enhance the MSVC makefile for better debugging symbol support. (Closed-Leaf check-in: c723ec2784 user: mistachkin tags: msvcDebug)

14:05
Bring in all the latest trunk changes, including the Common Table Expressions implementation. (check-in: 9b43e55919 user: drh tags: sessions)
11:16
Add test cases showing the use of ORDER BY on a recursive query to control depth-first versus breath-first search of a tree. (check-in: 83b0b29165 user: drh tags: trunk)
2014-01-23
14:44
Modifications to test files to omit any tests that intentionally access out-of-bounds locations in clang -fsanitize=address builds. (check-in: f4a701d55f user: dan tags: trunk)
2014-01-22
19:23
Avoid an extra seek when inserting records into the epheremal index used to ensure that rows returned by UNION recursive queries are unique. (check-in: 72c4b3f07a user: dan tags: trunk)
18:31
Fix harmless compiler warnings. (check-in: dea2ca6a15 user: drh tags: trunk)
18:16
Change the WITH RECURSIVE implementation to use a queue instead of a pair of tables. Add support for ORDER BY, LIMIT, and OFFSET on recursive queries. (check-in: b6cea42006 user: drh tags: trunk)
18:07
Add support for LIMIT and OFFSET in a recursive query. (Closed-Leaf check-in: 1945484e6b user: drh tags: cte-via-queue)
17:43
Update the spellfix virtual table to optimize queries of the form "SELECT ... FROM tbl WHERE rowid=?". (check-in: a0ba55ff05 user: dan tags: trunk)
17:28
Get ORDER BY working for recursive queries. (check-in: 37b343b018 user: drh tags: cte-via-queue)
13:35
Add new SelectDest codes, SRT_Queue and SRT_DistQueue in anticipation of adding ORDER BY support on recursive queries. Factor out the recursive query code generator into a separate procedure. (check-in: 3eb5f9f8d6 user: drh tags: cte-via-queue)
10:22
Fix a typo in a comment. No changes to code or tests. (check-in: cceacc0e79 user: dan tags: cte-via-queue)

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: b2671e1133 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: 5e43bf0132 user: dan tags: trunk)
01:13
Fix a couple comment typos and one overly long line. No functional changes. (Closed-Leaf check-in: c57deced09 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. Actual columns named "level" can still be accessed by including the table name qualifier. (check-in: cc1cb32178 user: drh tags: level-pseudocolumn)
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: 7d9e22187d user: dan tags: trunk)
18:25
Handle a few obscure problems that could manifest if a database corrupted in a certain way was written by a connection in the middle of a SELECT statement on the same db. (check-in: eba8a564e6 user: dan tags: trunk)
14:58
Remove an unused #define and add an assert(), both associated with WITH logic. (check-in: a06235e0f6 user: drh tags: trunk)
14:17
Do not run the tests in with2.test with SQLITE_OMIT_CTE builds. (check-in: 8a973912e9 user: dan tags: trunk)
2014-01-18
18:33
Add a sudoku solver to the recursive query tests in with1.test. (check-in: 679eff8759 user: drh tags: trunk)
15:59
Add extra test cases. No changes to code. (check-in: d38d485e58 user: dan tags: trunk)
15:22
Add asserts() for a couple of unreachable conditions. Add the Mandelbrot Set query as a test case. (check-in: 2ad4583c0c user: drh tags: trunk)
08:27
Avoid spurious "no such table" errors in statements of the form "INSERT INTO tbl WITH xxx AS (...) SELECT * FROM xxx". (check-in: cccff8a0b4 user: dan tags: trunk)
2014-01-17
20:36
Add extra tests to with2.test. (check-in: eecc325afd user: dan tags: trunk)
18:34
Minor simplification of error message text for a couple of errors associated with WITH clause processing. (check-in: 2031004d96 user: drh 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: a7323838bb 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: 9ca18a0191 user: drh tags: trunk)
15:27
Fix a compiler warning in selectPopWith(). (check-in: c8eb11635a user: drh tags: trunk)
15:15
Add support for common table expressions (WITH clauses). (check-in: 0171e3bb4f user: dan tags: trunk)
14:59
Fix some problems to do with WITH clauses and name resolution. (Closed-Leaf check-in: 6a549187ed user: dan tags: common-table-expr)
11:48
Remove some code from resolve.c that was only required for recursive cte references in sub-queries. Also a stray "finish_test" command in pagerfault.test. (check-in: f68c6c4d36 user: dan tags: common-table-expr)
2014-01-16
22:40
Add the ability for the authorizer callback to disallow recursive queries. (check-in: 9efc120a15 user: drh tags: common-table-expr)
21:59
Tweaks to error message text. (check-in: 090a77d978 user: drh tags: common-table-expr)
21:02
Improve the error messages used to report illegal recursive cte references. (check-in: 54eee9fe99 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: a296b73360 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: 16bd54783a 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: 6bfa387e82 user: dan tags: common-table-expr)
04:37
Merge trunk changes. Fix a possible NULL-pointer deference in WITH clause name resolution. (check-in: 7f953b568b user: drh tags: common-table-expr)
2014-01-15
00:24
Merge recent fixes from trunk. Cherrypick of [c43b59dac1], [a221aa82bb], [e1eba1fb09], and [1e131094b5]. (check-in: c697d2f83c user: mistachkin tags: branch-3.8.2)
2014-01-14
10:17
Fix harmless compiler warning in LEMON. (check-in: f61a70589a user: mistachkin tags: trunk)
10:17
For the Win32 VFS, defining winShmMutexHeld should be controlled by NDEBUG, not SQLITE_DEBUG. (check-in: 1e131094b5 user: mistachkin tags: trunk)
