2011-08-18
| ||
| 01:10 | Fix an error with OOM processing in the ANALYZE logic. (check-in: b26ec79c69 user: drh tags: stat3-enhancement) | |
|
2011-08-17
| ||
| 07:46 | Properly process x64 DLL exports, which do not contain a leading underscore, in the MSVC makefile. (check-in: d5936324d2 user: mistachkin tags: trunk) | |
| 02:19 | Add vdbesort.c to the MSVC makefile. (check-in: 8eaa2cd3f4 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: f01766f423 user: drh tags: trunk) | |
|
2011-08-16
| ||
| 17:06 | Fix a few harmless compiler warnings. Add SQLITE_ENABLE_STAT3 to the standard compiler warning script. (check-in: 3d68f9afee user: drh tags: stat3-enhancement) | |
| 02:07 | Allow the sqlite3VdbeJumpHere() routine to accept a negative or zero address if a prior memory allocation error has occurred. The new sqlite_stat3 logic needs this. (check-in: 9650d79628 user: drh tags: stat3-enhancement) | |
| 01:15 | Add the analyze8.test test module for sqlite_stat3. (check-in: 2c83ac89dc user: drh tags: stat3-enhancement) | |
|
2011-08-15
| ||
| 19:44 | Updated comments on the multiplexor extension. No changes to code. (check-in: 0f42ef697e user: drh tags: trunk) | |
| 15:37 | Fix an assert() in the merge-sort logic to account for I/O errors. (check-in: c1daa809a1 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: 26f2da24b0 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: bd04756b66 user: dan tags: trunk) | |
| 12:58 | Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. (check-in: 2504bcfb0c user: drh tags: stat3-enhancement) | |
| 12:02 | Fix a couple of typos in comments in analyze.c. (check-in: ae31dc67aa user: dan tags: stat3-enhancement) | |
|
2011-08-13
| ||
| 19:35 | Further testing and bug fixing for sqlite_stat3. Added the Index.avgEq field to index statistics. Fixed several problems in the query planner associated with stat3. (check-in: 89b2f70884 user: drh tags: stat3-enhancement) | |
| 15:25 | Add the sqlite_stat3.nDLT field. Use an linear congruence PRNG to choose which samples to select from among those with the same nEq field. (check-in: 1dcd24283e user: drh tags: stat3-enhancement) | |
| 10:47 | Fix the header comment on the implementation of the file_control_sizehint_test TCL command in test1.c. (check-in: 309198085f user: drh tags: trunk) | |
| 00:58 | The ANALYZE command picks for 15 samples for sqlite_stat3 with the largest nEq fields, plus 5 other evenly spaced samples. (check-in: 8225924ea0 user: drh tags: stat3-enhancement) | |
|
2011-08-12
| ||

| 16:34 | Update Makefile.in and configure to account for new source file vdbesort.c. (Closed-Leaf check-in: 69e4b41de2 user: dan tags: experimental) | |
| 16:30 | Merge latest trunk changes into experimental branch. (check-in: 7e515055f2 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: 1a8498d803 user: dan tags: experimental) | |
| 15:02 | Add the SQLITE_OMIT_MERGE_SORT pre-processor directive. To omit the code in vdbesort.c. (check-in: 4ced2394b1 user: dan tags: experimental) | |
| 11:59 | Add tests to improve coverage of vdbesort.c. (check-in: 87a15917d7 user: dan tags: experimental) | |
| 01:51 | Begin a branch that experimentally replaces sqlite_stat2 with a new table called sqlite_stat3 that will hopefully facilitate better query planning decisions. (check-in: 52e1d7e8dd user: drh tags: stat3-enhancement) | |
|
2011-08-10
| ||
| 01:52 | Make the openDirectory routine in os_unix.c overrideable so that it can be turned into a harmless no-op for the chromium sandbox. (check-in: 6b236069e1 user: drh tags: trunk) | |
|
2011-08-09
| ||
| 18:14 | Add command-line utilities "offsets.c" and "extract.c" for use in low-level analyzsis of database files. (check-in: dfa22ed438 user: drh tags: trunk) | |
|
2011-08-08
| ||
| 23:48 | In os_unix.c, do not open the directory containing the database file when the database file is opened. Instead, wait until time to fsync() the directory. And do not report an error if the open fails, since some systems (Ex: AIX and a chromium sandbox) are unable to open and fsync directories. (check-in: 713b1b7dc1 user: drh tags: trunk) | |
| 23:18 | Allow the unlink() system call to be overridden in os_unix.c. (check-in: 8d1b5c3ac0 user: drh tags: trunk) | |
| 19:26 | Remove redundant parameter from vdbeSorterInitMerge() in vdbesort.c. (check-in: eec8c0df07 user: dan tags: experimental) | |
| 17:18 | Add code to actually use the sqlite_stat2.cnt field in the query planner. This changes some plans resulting in a few failures in analyze5.test. (Closed-Leaf check-in: d1248165e3 user: drh tags: query-planner-tweaks) | |
| 16:44 | Add fault-injection and other tests (and fixes) to improve coverage of vdbesort.c. (check-in: 0e6defa6aa user: dan tags: experimental) | |
|
2011-08-07
| ||
| 01:31 | Remove relevant elements from the sqlite_stat2 table when doing a DROP INDEX or DROP TABLE. (check-in: 3c8f97ae52 user: drh tags: trunk) | |
| 00:21 | The ANALYZE command adds the sqlite_stat2.cnt column if it does not already exist. (check-in: 794fde6f91 user: drh tags: query-planner-tweaks) | |
|
2011-08-06
| ||
| 19:48 | The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. (check-in: 6d1e2372fe user: drh tags: query-planner-tweaks) | |
| 15:09 | Fix a problem with building large indexes introduced by the previous commit. (check-in: 038ec9ea92 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: 8051c1767c user: dan tags: experimental) | |
| 02:03 | Merge together the fork in the query-planner-tweaks branch. (check-in: 2daab6bd42 user: drh tags: query-planner-tweaks) | |
| 01:22 | Fix a compiler warning when STAT2 is off. More test cases. Fix legacy tests to deal with the new STAT2 logic. (check-in: 7e914aa999 user: drh tags: query-planner-tweaks) | |
|
2011-08-05
| ||
| 22:31 | Bug fixes to the sample-count logic for STAT2. A few test cases added. (check-in: e93c248c84 user: drh tags: query-planner-tweaks) | |
| 21:13 | Add a column to the sqlite_stat2 table that contains the number of entries with exactly the same key as the sample. We do not yet do anything with this extra value. Some tests in analyze2.test are failing. (check-in: eb43422827 user: drh tags: query-planner-tweaks) | |
| 11:49 | Minor internal changes to vdbesort.c. Also, default to merging lists together 16 at a time. (check-in: 9ddc324a34 user: dan tags: experimental) | |
| 01:09 | Allow the sqlite_stat2 table to contain a number of samples other than the default of 10. (check-in: b9d41c3490 user: drh tags: query-planner-tweaks) | |
|
2011-08-04
| ||
| 18:43 | Fix a comment in vdbesort.c. (check-in: db8518cab8 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: a4770d079c user: dan tags: experimental) | |
|
2011-08-03
| ||
| 22:06 | Merge the winopen-retry-logic branch into trunk. The biggest change here is to test scripts, which should now use such as copy_file and delete_file from tester.tcl rather than the raw file commands of TCL. (check-in: b90c28be38 user: drh tags: trunk) | |
| 21:46 | Merge the latest trunk changes into the sessions branch. (check-in: c570903608 user: drh tags: sessions) | |
| 21:32 | Avoid segfaulting on an incremental blob write if SQLITE_ENABLE_PREUPDATE_HOOK set but no pre-update hooks are defined. (check-in: 62c4463404 user: drh tags: sessions) | |
| 16:40 | Update the OP_Move opcode to shift the pScopyFrom pointer of aliases when compiled with SQLITE_DEBUG. Ticket [d63523637517386191]. (check-in: a2135ad130 user: drh tags: trunk) | |
| 01:07 | Adjust the output row estimating logic when using STAT2. (check-in: c8ba8855d8 user: drh tags: query-planner-tweaks) | |
|
2011-08-02
| ||
| 23:45 | Add explanatory comment to the win32lock-2.2 test case. (Closed-Leaf check-in: 4cb17881d9 user: mistachkin tags: winopen-retry-logic) | |
