28 check-ins using file src/sqlite.h.in version 469aed42

2018-05-08
23:17
Correctly format the STAT1 and STAT4 content in the output from the ".fullschema" command in the CLI. Fix for ticket [e63a34a0045832dc850367552]. check-in: 0c3f128f user: drh tags: trunk
22:47
Experiments with routines for processing GeoJSON. check-in: d22fbff2 user: drh tags: geojson
13:03
Fix a harmless compiler warning in fuzzcheck. Add new OSSFuzz test cases to the test case library. check-in: d2619746 user: drh tags: trunk
12:49
Fuzz test cases for UPSERT. check-in: fd11fbd2 user: drh tags: trunk
2018-05-07
18:41
Activate the cell-overwrite optimization for index b-trees. check-in: a68697d1 user: drh tags: trunk
17:27
Improved comments on the cell-overwrite optimization code. check-in: a4fe966d user: drh tags: trunk
11:48
On an UPDATE, try to overwrite an existing btree cell with the modified content, if the old and new cell are the same size. Use memcmp() first to avoid dirtying pages that are unchanged. check-in: 5887d8be user: drh tags: trunk
11:37
Fix harmless compiler warnings associated with the new EXPLAIN QUERY PLAN logic. check-in: 374d8e26 user: drh tags: trunk
11:29
Fix harmless compiler warnings in the cell-overwrite logic. Closed-Leaf check-in: 3e11dc31 user: drh tags: cell-overwrite-prototype
02:50
Backout change [05fee1a21ea398f1e4d6f1cf3] because it does not take into account the LD_LIBRARY_PATH environment variable used by dl_open(). check-in: b348d119 user: drh tags: trunk
2018-05-05
16:50
In an ORDER BY LIMIT, make sure the ORDER BY expression evaluator does not try to reuse values from the result set if the result set has not yet be computed. This fixes a bug in the recent deferred-row loading optimization, check-in [c381f0ea57002a264fd958b28e]. OSSFuzz discovered the problem. check-in: 5d61e75f user: drh tags: trunk
01:23
Fix a slightly incorrect corruption detection branch in the btree logic. check-in: 9191ff67 user: drh tags: trunk
2018-05-04
19:18
Merge enhancements from trunk. check-in: 9650f71b user: drh tags: cell-overwrite-prototype
18:32
Fix requirements marks. No code changes. check-in: 7fdad122 user: drh tags: trunk
04:49
For the amalgamation-tarball, enable FTS5 and JSON1 by default and provide a new --enable-debug option that actives debugging facilities. check-in: 03edecaf user: drh tags: trunk
00:39
Make a separate limb in the EXPLAIN QUERY PLAN output for the various lines associated with the OR-optimization. check-in: 75ac7b4e user: drh tags: trunk
2018-05-03
23:20
In ORDER BY LIMIT queries, try to evaluate the ORDER BY terms first, and it it becomes clear that the row will not come in under the LIMIT, then skip evaluation of the other columns. check-in: c381f0ea user: drh tags: trunk
22:52
Fix a branch that has become unreachable due to recent enhancements. check-in: 81ab5e0d user: drh tags: trunk
21:51
Improved security for VACUUM. This check-in combines the fixes of [ab0d99d0b5ede] and [27754b74ddf646] in a way that is less likely to to be broken by future changes. check-in: 260fc696 user: drh tags: trunk
19:56
Overhaul of EXPLAIN QUERY PLAN. The output is now in the form of a tree. More details of the query plan are shown, and what is shown is truer to what actually happens. check-in: ff01bbda user: drh tags: trunk
16:56
Fix various error handling conditions on the cell overwrite optimization. Fix a test case so that it works with the new optimization. check-in: f89b54f4 user: drh tags: cell-overwrite-prototype
14:07
The BtCursor.info fields are only valid if info.nSize!=0. check-in: 54c537ee user: drh tags: cell-overwrite-prototype
13:56
Add more corruption checking to the cell overwrite logic. check-in: 58d14afe user: drh tags: cell-overwrite-prototype
12:57
Bug fixes in the overwrite optimization. check-in: 0cb6cd2a user: drh tags: cell-overwrite-prototype
03:59
The sqlite3BtreeInsert() routine tries to overwrite an existing cell with modified content if the new content is the same size. Pages are only dirtied if they change. This prototype works some, but still has issues. check-in: 489451b3 user: drh tags: cell-overwrite-prototype
2018-05-02
15:00
Prevent VACUUM from running any commands in sqlite_master.sql other than CREATE statements. That is all that should be there anyhow. This fixes a problem discovered by OSSFuzz. Test cases in TH3. check-in: ab0d99d0 user: drh tags: trunk
08:12
Fix a problem in the xBestIndex method of the closure extension causing it to allocate non-contiguous argvIndex values in some cases (an "xBestIndex malfunction" error). check-in: 0c671507 user: dan tags: trunk
03:01
Add sqlite3_win32_set_directory8() and sqlite3_win32_set_directory16() functions. check-in: 22089ea2 user: mistachkin tags: trunk
