20 check-ins using file src/os_win.c version 3fca1bfd

2014-08-11
17:37
Add a few more requirements tests. check-in: b5652439 user: drh tags: trunk
15:54
Updates to evidence marks and requirements. No changes to code. check-in: 62d38308 user: drh tags: trunk
14:21
Fix harmless compiler warnings. check-in: 52b03f04 user: drh tags: trunk
13:53
Changes that will perhaps enable SQLite to work better on VxWorks. check-in: de27c742 user: drh tags: trunk
2014-08-08
18:26
Update requirements marks. No changes to code. check-in: 7556bd9a user: drh tags: trunk
17:49
Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. check-in: bdaa6947 user: drh tags: trunk
17:25
Fix a buffer overrun in the previous commit. Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. check-in: 299b9570 user: dan tags: query-planner-fix
15:38
The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. check-in: 36b7c5ce user: drh tags: trunk
12:51
Reworking the documentation on integer result codes. This is a comment and documentation change only. There are no changes to code. check-in: 54f1df7b user: drh tags: trunk
2014-08-07
20:42
When the estimated sorting cost overwhelms the estimated lookup cost, ensure that lookup costs are still taken into account when selecting a lookup algorithm. check-in: 2af630c5 user: drh tags: trunk
20:37
Clarify the computation of compatible isOrdered by in the plan solver of the query planner. Closed-Leaf check-in: b5e8fd57 user: drh tags: query-planner-fix
20:25
Remove the extraneous debugging printf() from the previous check-in. check-in: 8f04d2c0 user: drh tags: query-planner-fix
16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. check-in: ec5d84ba user: drh tags: query-planner-fix
2014-08-06
18:50
A couple more harmless compiler warnings eliminated. check-in: bcf6d775 user: drh tags: trunk
17:49
Fix two more harmless compiler warnings. Make sure the fts3_unicode2.c file is in sync with mkunicode.tcl. check-in: a2a60307 user: drh tags: trunk
14:36
Fix harmless compiler warnings. In the command-line shell, report if the ".system" command returns a non-zero result. check-in: 1202e977 user: drh tags: trunk
12:00
Merge the second InterlockedCompareExchange() fix from trunk. check-in: 69018967 user: drh tags: sessions
11:58
Fix an obsolete comment in the func.c source file. No changes to code. check-in: 5c6bb57d user: drh tags: trunk
11:57
On the windows VFS, do not try to make InterlockedCompareExchange an overloadable function, since sometimes it is a macro. check-in: ab1a751e user: drh tags: trunk
