20 check-ins using file ext/rtree/geopoly.c version cdf79727

18:17
The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. (Leaf check-in: 857a1b01 user: drh tags: query-planner-debug)

18:05
Add an ALWAYS on an unreachable branch in the ALTER TABLE logic. (check-in: ebcd4523 user: drh tags: trunk)
11:13
Change a type in shell.c.in from "int" to "sqlite3_int64" in order to avoid a compiler warning and possible integer overflow. (check-in: bf0a6634 user: dan tags: trunk)
2018-10-02
20:16
Add an additional assert() verifying mutex invariants on the unixShmSystemLock() routine in the unix VFS. (check-in: cb151106 user: drh tags: trunk)
19:58
Additional field name changes and commit fixes associated with shared-memory locking in the unix VFS, to improve maintainability. No logic changes. (check-in: 9280774a user: drh tags: trunk)
19:36
Fix comments and refactor some names associated with shared-memory locking in the Unix VFS. No logical changes. (check-in: 3e9f1635 user: drh tags: trunk)
2018-10-01
21:41
Add the "PRAGMA table_xinfo" command that works like table_info but also shows hidden columns in virtual tables and adds the "hidden" boolean column. (check-in: defa0515 user: drh tags: trunk)
21:36
Test case for PRAGMA table_xinfo. (Closed-Leaf check-in: 7694b9bc user: drh tags: pragma-table-vinfo)
21:26
Change the name of the pragma to PRAGMA table_xinfo. Improve the mkpragmatab.tcl script to reuse column names where appropriate. (check-in: 2fdd0689 user: drh tags: pragma-table-vinfo)
18:28
Add the extra "hidden" column to the end of the PRAGMA table_vinfo output. (check-in: cf1b7613 user: drh tags: pragma-table-vinfo)
17:33
Speed up xAccess() calls made on an RBU VFS when there are lots of open connections. (check-in: 310b4b65 user: dan tags: trunk)
17:15
Bring the PRAGMA table_vinfo statement up to date with trunk. (check-in: 6f606f99 user: drh tags: pragma-table-vinfo)
13:54
Fix a potential crash that can occur while reading an index from a corrupt database file. The corruption is a record-header-size that is larger than 0x7fffffff. Problem detected by OSSFuzz against GDAL and reported to us (with a suggested fix) by Even Rouault. The test case is in TH3. (check-in: 8ac2cdda user: drh tags: trunk)
07:04
Fix a problem with ALTER TABLE commands when the schema features an INSTEAD of trigger that uses NEW.* or OLD.*. (check-in: c52f457e user: dan tags: trunk)
2018-09-28
23:53
Fix test cases so that they work with ICU. (check-in: d04b2013 user: drh tags: trunk)
21:11
Merge latest begin-concurrent changes into this branch. (check-in: 6f3dd980 user: dan tags: begin-concurrent-pnu)
20:58
Merge latest trunk into this branch. (check-in: 86750c92 user: dan tags: begin-concurrent)
20:46
Have sqlite3changegroup_output_strm() call its output function more regularly. (check-in: 8467c31a user: dan tags: trunk)
18:51
Fix a bug in the sqlite_memstat virtual table that was causing it to report the amount of memory used as zero bytes. (check-in: 8a758a87 user: drh tags: trunk)
14:01
Add the geopoly_regular(X,Y,R,N) function to the geopoly extension. (check-in: 4505bbae user: drh tags: trunk)
