18:34
A proposed fix for the DESC ORDER BY bug of ticket [4dd95f6943fbd18]. Seems to work, but lots more testing is needed prior to moving to trunk. check-in: 614a038a user: drh tags: desc-orderby-fix-1

2013-03-08
18:16
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. check-in: f2fecfb2 user: dan tags: trunk
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: 69746ef7 user: dan tags: experimental

Failed merge experimental branch with trunk. check-in: 4e6e07a6 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: d7343558 user: drh tags: trunk
2013-02-26
18:54
In the incrvacuum3 test, add missing call to the Tcl close command. check-in: cd806723 user: mistachkin tags: trunk

Fix off-by-one bug in [c3939d2491] uncovered by th3. check-in: 66f9faa9 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: b73847f1 user: dan tags: incr-vacuum-opt
2013-02-22
20:57
Fix a problem with the previous commit. check-in: 720a3cea user: dan tags: incr-vacuum-opt

2013-02-12
22:20
Improve memory allocation error handling on WinCE. check-in: cdbca259 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: b7222a2b user: drh tags: trunk

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: b016b754 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: f78395c8 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: a917c1f0 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: 98bf668a 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: 497ee36c 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: ae565ff3 user: drh tags: trunk
2013-01-28
22:52
Fix an issue with the SQLITE_TESTCTRL_EXPLAIN_STMT and compound queries with multiple terms. check-in: a6499c25 user: drh tags: trunk
19:00

2013-01-25
19:11

18:33
Enhance the command-line shell so that adding a non-zero numeric argument to the ".exit" command causes an immediate exit without cleaning up. This can be used (for example) to cause journal files to be left behind. check-in: 8ba951d1 user: drh tags: trunk
15:59
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: 93b159da user: drh tags: trunk
15:31
Further improvements to showwal.c: Reset the checksum after each frame so that only individual checksum failures are shown. And only show failures, not correct checksums. check-in: 4e2bf575 user: drh tags: trunk
15:09
Enhance the "showwal" utility program to show checksum failures on frames. check-in: a7f6d198 user: drh tags: trunk

Fix the activate_extensions pragma so that it is a no-op when the required argument is omitted. check-in: 6195ebd8 user: drh tags: trunk
17:08
Enhance the query planner to exploit transitivity of join constraints in a multi-way join. check-in: 13171eb5 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: d5ebb787 user: drh tags: trunk
2013-01-15

11:27
Fix the date on the new orderby3.test test case. check-in: 7249bfc2 user: drh tags: trunk

Remove superfluous text from a comment. check-in: e9ac5339 user: mistachkin tags: trunk

Do not use umask() since it change the umask for the entire process, not just the thread using SQLite. Make whatever permission changes are needed using fchmod() after the file is created, instead. check-in: 6c4c2b7d user: drh tags: trunk
19:22
Fix an out-of-order local variable declaration in test_regexp.c. check-in: 8285b15a 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: 7fecced4 user: drh tags: trunk

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: 8183d8d7 user: dan tags: trunk

Generalize the min/max optimization so that if an appropriate index exists, the index it can be used by any aggregate query that contains only a single max() or min() and does not contain a GROUP BY clause. check-in: 52e75594 user: drh tags: trunk

Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object. The COLLATE operator now becomes a separate instance of Expr in the expression tree. The code generator looks up the correct collating function as needed, rather than referring to Expr.pColl. check-in: 8542e618 user: drh tags: trunk
