40 check-ins using file src/vdbeaux.c version 8fb978eb

2011-08-24
01:25
Changes to test_quota.c to make quota groups persistent even after files are closed. Files remain a part of the quota group until they are deleted. (check-in: 04111ce9 user: drh tags: trunk)
2011-08-23
23:41
Simplifications to the SQLITE_PAGECACHE_BLOCKALLOC logic. Reduce the number of difficult-to-reach branches. (check-in: d5d835fe user: drh tags: trunk)
20:11
If the application-defined openDirectory() function returns SQLITE_CANTOPEN, then silently ignore the error. This allows the chromium sandbox to disallow opening of directories without causing errors. (check-in: 880b5115 user: drh tags: trunk)
19:46
Change the way the "crash" VFS (test6.c) handles SQLITE_FCNTL_SIZE_HINT. (check-in: 40dd8a60 user: dan tags: trunk)
18:06
Merge latest trunk changes into the apple-osx branch. (check-in: c5f7977b user: dan tags: apple-osx)
16:41
Have the "crash" VFS used by the tcl tests (test6.c) handle SQLITE_FCNTL_SIZE_HINT internally, instead of passing it directly through to the underlying VFS. This is important if the crash VFS is simulating non-default device characteristics such as SQLITE_DEVCAP_SEQUENTIAL or ATOMIC. (check-in: fac8bc8f user: dan tags: trunk)
13:27
Ifdef out routines in pcache1.c that are used only when SQLITE_PAGECACHE_BLOCKALLOC is defined. (check-in: 0da292da user: drh tags: trunk)
12:50
Merge the PAGECACHE_BLOCKALLOC changes into trunk. (check-in: 768c1846 user: drh tags: trunk)
11:47
When copying a rollback mode database over a WAL database using the backup API, leave the destination database in WAL mode (instead of switching it to rollback mode). Fix for [af95b8c609]. (check-in: 35e6ac18 user: dan tags: trunk)
05:10
Change to test instrumentation of os_unix.c: Regard IO errors that occur within SQLITE_FCNTL_SIZE_HINT requests as benign. (This check-in was intended for trunk and went onto the branch accidentally.) (Closed-Leaf check-in: ca47da2a user: dan tags: pager-blockalloc)
00:01
Remove a branch that is always true. (check-in: a6568192 user: drh tags: trunk)
2011-08-22
20:33
Remove an unreachable branch in the FK code. (check-in: 6c227cc8 user: drh tags: trunk)
14:55
Modify test cases so that veryquick.test passes with PAGECACHE_BLOCKALLOC defined. (check-in: c6100070 user: dan tags: pager-blockalloc)
09:54
Fix for [b1d3a2e531]. (check-in: 3f3acee4 user: dan tags: trunk)
2011-08-19
18:15
Experimental change: If SQLITE_PAGECACHE_BLOCKALLOC is defined, instead of allocating pages one at a time, allocate blocks of between 15 and 63 pages in a single allocation. (check-in: 63597097 user: dan tags: pager-blockalloc)
14:54
When retrying a write() after an EINTR error on unix, be sure to also rerun the previous lseek(). Ticket [e59bdf6116036a] (check-in: 21452f3a user: drh tags: trunk)
2011-08-18
17:47
Ensure that the Tcl "db onecolumn" command returns an empty string if the SELECT statement returns zero rows. (check-in: 928bcaf0 user: dan tags: trunk)
2011-08-17
07:46
Properly process x64 DLL exports, which do not contain a leading underscore, in the MSVC makefile. (check-in: d5936324 user: mistachkin tags: trunk)
02:19
Add vdbesort.c to the MSVC makefile. (check-in: 8eaa2cd3 user: mistachkin tags: trunk)
00:40
Use OP_Sort rather than OP_Rewind in order to sort the content of a new index on the CREATE INDEX statement. Add an ALWAYS() to the merge sort logic to document an unreachable branch. (check-in: f01766f4 user: drh tags: trunk)
2011-08-15
19:44
Updated comments on the multiplexor extension. No changes to code. (check-in: 0f42ef69 user: drh tags: trunk)
15:37
Fix an assert() in the merge-sort logic to account for I/O errors. (check-in: c1daa809 user: drh tags: trunk)
15:27
New makefile target "sqlite3-debug.c" builds an amalgamation that include appropriate "#line" macros relating the code back to the original source files. (check-in: 26f2da24 user: drh tags: trunk)
14:41
When opening a temporary file to use in a merge-sort, pass SQLITE_OPEN_TEMP_JOURNAL instead of SQLITE_OPEN_TEMP_DB. This is a better fit, as merge-sort files are written and read sequentially like journal files. (check-in: bd04756b user: dan tags: trunk)
2011-08-13
10:47
Fix the header comment on the implementation of the file_control_sizehint_test TCL command in test1.c. (check-in: 30919808 user: drh tags: trunk)
2011-08-12
16:47
Merge the experimental changes to use a merge-sort when creating an index into the trunk. (check-in: 346a453d user: dan tags: trunk)
16:34
Update Makefile.in and configure to account for new source file vdbesort.c. (Closed-Leaf check-in: 69e4b41d user: dan tags: experimental)
16:30
Merge latest trunk changes into experimental branch. (check-in: 7e515055 user: dan tags: experimental)
16:11
Remove an unused parameter from a function in vdbesort.c. Fix some comments and other details in the same file. (check-in: 1a8498d8 user: dan tags: experimental)
15:02
Add the SQLITE_OMIT_MERGE_SORT pre-processor directive. To omit the code in vdbesort.c. (check-in: 4ced2394 user: dan tags: experimental)
11:59
Add tests to improve coverage of vdbesort.c. (check-in: 87a15917 user: dan tags: experimental)
2011-08-08
19:26
Remove redundant parameter from vdbeSorterInitMerge() in vdbesort.c. (check-in: eec8c0df user: dan tags: experimental)
16:44
Add fault-injection and other tests (and fixes) to improve coverage of vdbesort.c. (check-in: 0e6defa6 user: dan tags: experimental)
2011-08-06
15:09
Fix a problem with building large indexes introduced by the previous commit. (check-in: 038ec9ea user: dan tags: experimental)
12:01
In temp files used for merge sorting, store the size of each packed-memory-array at the start of the array itself. This is to avoid having to store the offsets of all arrays in the (potentially very large) file in main-memory. (check-in: 8051c176 user: dan tags: experimental)
2011-08-05
11:49
Minor internal changes to vdbesort.c. Also, default to merging lists together 16 at a time. (check-in: 9ddc324a user: dan tags: experimental)
2011-08-04
18:43
Fix a comment in vdbesort.c. (check-in: db8518ca user: dan tags: experimental)
12:14
Change to using packed-memory-arrays instead of b-trees when performing an offline merge-sort for CREATE INDEX. This makes it easier to control the number of disc seeks required when merging. (check-in: a4770d07 user: dan tags: experimental)
2011-08-02
10:56
Minor fixes to vdbesort.c code in preparation for a major rework. (check-in: 7f339c0e user: dan tags: experimental)
2011-07-12
14:28
Experimental support for speeding up CREATE INDEX commands using an offline merge sort. (check-in: 30dbf0fe user: dan tags: experimental)
