07:10
If SQLITE_OMIT_UTF16 is defined, avoid setting the 'enc' field of Schema objects to any value except SQLITE_UTF8. Otherwise, assert() statements may fail or spurious SQLITE_NOMEM errors may be returned at the vdbe level later on. (Closed-Leaf check-in: 69746ef787 user: dan tags: experimental)

01:41
Fix an operator precedence problem on the [1d8086902e] check-in. (Closed-Leaf check-in: 4f5f3aebe8 user: drh tags: ex-robust-open)

Failed merge experimental branch with trunk. (check-in: 4e6e07a60e user: dan tags: ex-robust-open)

01:07
Always use strncmp() rather than memcmp() when comparing strings where one or other string might be less than the length parameter, since optimized versions of memcmp() might read past the first difference and in so doing generate an access violation. (check-in: d73435587b user: drh tags: trunk)
2013-02-26
18:54
In the incrvacuum3 test, add missing call to the Tcl close command. (check-in: cd80672384 user: mistachkin tags: trunk)
12:57
When comparing names during name resolution, make sure the names match exactly and that one name isn't merely a prefix of the other. Fix for ticket [7a31705a7e6c95d51]. (check-in: c2d5a23b1a user: drh tags: trunk)
06:14
Change the way test script incrvacuum3.test copies database files in order to avoid trying to read the (locked) 512 byte 'pending-byte' region. (check-in: fa1842e462 user: dan tags: trunk)
05:44
Prevent Tcl file encoding issues in the tests for the unicode() and char() functions. (Closed-Leaf check-in: d2e7dfca5a user: mistachkin tags: funcTestEncoding)

Merge the incr-vacuum-opt branch with the trunk. (check-in: 26e235b7a4 user: dan tags: trunk)
12:06
Add test file incrvacuum3.test. No code changes. (Closed-Leaf check-in: bf57534188 user: dan tags: incr-vacuum-opt)

17:49
Fix off-by-one bug in [c3939d2491] uncovered by th3. (check-in: 66f9faa9a9 user: dan tags: incr-vacuum-opt)
16:40
If a rollback mode transaction reduces the size of the database file, avoid actually truncating the file until after the transaction has been committed (but before the db has been unlocked). This means pages that are removed from the database by truncating the file need not be journalled. (check-in: b73847f17b user: dan tags: incr-vacuum-opt)

20:57
Fix a problem with the previous commit. (check-in: 720a3ceafc user: dan tags: incr-vacuum-opt)

2013-02-16
02:41
Fix an unsafe VM register deallocation. (check-in: cfba2c8dad user: drh tags: trunk)
2013-02-15

Check for a NULL handle prior to manually calling winClose. (check-in: 843e1c543a user: mistachkin tags: trunk)
2013-02-14
16:16
Verify that the schema has not changed before running PRAGMA table_info, index_list, index_info, and foreign_key_list. (check-in: 82952d08f3 user: drh tags: trunk)
2013-02-13

Add recent API additions to the extension mechanism. (check-in: 7e10a62d0e user: drh tags: trunk)
01:00
Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. (check-in: 2cef8b68f0 user: drh tags: trunk)
2013-02-12
22:20
Improve memory allocation error handling on WinCE. (check-in: cdbca259da user: drh tags: trunk)
22:09
A bug report coming from from Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=840377) describes an infinite recursion. We are unable to reproduce the problem. Nevertheless, this check-in should prevent the problem from ever occurring again. (check-in: b7222a2bd0 user: drh tags: trunk)
09:46
Improve memory allocation error handling on WinCE. (Closed-Leaf check-in: 09dfc0c915 user: mistachkin tags: wince)
2013-02-11
13:47
Add extended error codes for all SQLITE_CONSTRAINT errors. (check-in: 939d828274 user: drh tags: trunk)
2013-02-09
15:37
Rename SQLITE_CONSTRAINT_RAISE to SQLITE_CONSTRAINT_TRIGGER. Put the extended constraint error codes in alphabetical order. Add many test cases for the extended constraint error codes. (Closed-Leaf check-in: 3f67437536 user: drh tags: constraint-error-codes)
13:58
Add extended error codes for constraint errors. (check-in: 5461104668 user: drh tags: constraint-error-codes)
2013-02-08
23:18
Fix a potential NULL-pointer dereference following an OOM error in the query planner logic for virtual tables with OR-connected terms. (Closed-Leaf check-in: 71b6c26053 user: drh tags: IN-with-ORDERBY)
20:39
Make sure the virtual tables that take advantage of IN operators sort the RHS of the IN operator in the correct order according to the ORDER BY clause. (check-in: b016b7546d user: drh tags: IN-with-ORDERBY)
18:48
Loop through the elements on the RHS of an IN operator in reverse order when the ORDER BY clauses specifies DESC. (check-in: f78395c889 user: drh tags: IN-with-ORDERBY)
16:04
Allow the "a=?1 OR a=?2" to "a IN (?1,?2)" transformation to work on virtual tables again. This was formerly restricted because virtual tables could not optimize IN terms. (See check-in [fad88e71cf195e].) But IN terms are now used by virtual tables (as of check-in [3d65c70343]) so the restriction can now be removed. (check-in: a917c1f092 user: drh tags: IN-with-ORDERBY)
2013-02-07
21:15
Allow an index to be used for sorting even if prior terms of the index are constrained by IN operators. (check-in: 98bf668ab1 user: drh tags: IN-with-ORDERBY)

2013-01-29
23:55
Fix LIMIT and OFFSET so that they work and do not leak memory even on complex queries involving deeply nested views of UNION ALL compounds. Ticket [db4d96798da8]. Secondary to ticket [d58ccbb3f1b7]. (check-in: 497ee36cb8 user: drh tags: trunk)
19:14
New debugging pragmas: PRAGMA vdbe_debug=ON is short-hand for the sql_trace, vdbe_listing, and vdbe_trace pragmas. PRAGMA vdbe_debug enables tracing of sqlite3VdbeAddOp() calls. None of this is active unless compiled with SQLITE_DEBUG. (check-in: ae565ff3e0 user: drh tags: trunk)
2013-01-28
22:52

19:00
Issue an error message and quit (rather than overflowing a reference counter) if the number of references to a table exceeds the maximum due to nested UNION views. Fix for ticket [d58ccbb3f1]. (check-in: c2462a95ed user: drh tags: trunk)
18:18
Cause the command-line shell to issue an error message if you give something that does not look like a boolean value to a dot-command that wants a boolean argument. (check-in: b4d94947fc user: drh tags: trunk)
2013-01-26
19:31
Add a single test case to fts4unicode.test to verify that title-case maps to lower case. (check-in: 955a9459da user: drh tags: trunk)

Add btree-page decoding logic to showwal.c. Commands of the form: "showwal $FILE 123bmc" show the content of the btree page in frame 123. "b" means decode the btree. "c" means show cell content. "m" means give a map of the btree page. (check-in: 93b159da5d user: drh tags: trunk)
15:31

Improved comments explaining the operation of the findTerm() utility routine in where.c. Increase the maximum number of levels of transitivity from 4 to 11. (check-in: fe152f8b04 user: drh tags: transitive-constraints)
2013-01-16
20:33

17:08
Enhance the query planner to exploit transitivity of join constraints in a multi-way join. (check-in: 13171eb5dc user: drh tags: transitive-constraints)
00:46
Improvements to query planning for joins: Avoid unnecessary calls to "optimal scan" checks in cases where table reordering is not possible. Make sure optimal scan checks are carried out for CROSS JOINs and LEFT JOINs. (check-in: d5ebb78778 user: drh tags: trunk)
2013-01-15
18:49
Fix a missing word in a comment. Enhance the "wheretrace" debugging output to show the estimated cost of each table option while planning the join order. (check-in: ac4e119a87 user: drh tags: trunk)

2012-12-18
19:36
Optimize the degenerate case of a FROM clause table name enclosed all by itself inside parentheses. Generate code as if the parentheses did not exist, rather than the old behavior of manifesting the parenthesized table into a transient table. Also, tag every FROM-clause SELECT subquery that is generated by a parenthesized FROM-clause expression using the SF_NestedFrom flag. The new SF_NestedFrom flag is not yet used for anything. (check-in: 7fecced466 user: drh tags: trunk)

11:59
On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb]. (check-in: 8183d8d7ae user: dan tags: trunk)
2012-12-17
22:32

Fix the virtual table IN optimizer so that it work even if the virtual table implementation leaves the sqlite3_index_info.aConstraintUsage[].omit flag clear for an equality constraint that it intends to use. (check-in: d6e045f89c user: drh tags: vtab-IN-opt)
2012-12-13
