00:32
Change the sqlite3Atoi64() routine so that it returns failure if not all of the input characters are consumed, even if it consumed all characters up to the first 0x00. This has no impact on external APIs as far as I can tell. check-in: 46d4ffff user: drh tags: trunk
2016-04-27
18:54

15:24
More simplification of the sqlite3AtoF() routine. Add special comments to indicate branches that are for optimization purposes only and that give the correct answer even if always or never taken. check-in: 0065fe97 user: drh tags: trunk
11:24
Fix a couple of test script problems on this branch. Both related to the fact that temp database page sizes can no longer be changed by VACUUM or the backup API after the temp db is populated. check-in: 6bb5aa2b user: dan tags: tempfiles-25
02:35

19:20
Fix some unreachable branches in the pager. check-in: 3ae44770 user: drh tags: tempfiles-25

02:20
When checking for the WHERE-clause push-down optimization, verify that all terms of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket [f7f8c97e97597]. check-in: ec215f94 user: drh tags: trunk
01:43
Fix a typo in the Makefile. check-in: d0a579b3 user: mistachkin tags: trunk

18:13
Add the sqlite3rbu_vacuum() API, to create an RBU handle that can be used to rebuild a database in the same way as the VACUUM command. check-in: bd4a6f83 user: dan tags: trunk
16:44
If a call to sqlite3rbu_close() on an rbu handle opened by sqlite3rbu_vacuum() returns other than SQLITE_OK, delete the contents of the rbu_state table. This ensures that if an RBU vacuum operation either completes successfully or encounters an error, the next call to sqlite3rbu_vacuum() with the same parameters starts a new RBU vacuum operation. Closed-Leaf check-in: 6e4ac704 user: dan tags: rbu-vacuum
15:44
Merge the latest changes from trunk. Closed-Leaf check-in: 8183fa68 user: drh tags: skip-ahead-distinct

01:58
Test cases for SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION. Closed-Leaf check-in: debafa5e user: drh tags: load-ext-security
01:30
Revert sqlite3_enable_load_extension() to its original long-standing behavior. Add SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION which will enable only the C-API and leave the SQL function disabled. check-in: b2ae5bfa user: drh tags: load-ext-security
2016-04-20
20:08
Add a documentation comment for sqlite3rbu_vacuum() to sqlite3rbu.h. check-in: da5c753d user: dan tags: rbu-vacuum
19:30

18:31
Fix a locking race condition in Windows 10 that can occur when two or more processes attempt to recover the same hot journal at the same time. check-in: 38a4e9d9 user: drh tags: trunk

00:30
API Change: Modify sqlite3_enable_load_extension() so that it only enables/disables the load_extension() SQL function, and leaves the C-APIs enabled at all times. In this way, applications can enable extension loading for the C interface without having to expose that capability to the SQL. check-in: edb454e4 user: drh tags: load-ext-security
2016-04-19
19:27
Updates to ensure the values of PRAGMA settings like "page_size", "auto_vacuum", "user_version" and "application_id" are not lost when a database is RBU vacuumed. check-in: 74ffea76 user: dan tags: rbu-vacuum
17:11
When an RBU vacuum is started on a db identified using a URI filename, pass the same URI parameters when creating the new version of the db. This ensures that RBU vacuum works with password protected databases. check-in: ca021ba8 user: dan tags: rbu-vacuum
16:20
Detect attempts to use rbu vacuum on a wal mode database (not allowed). And attempts to write to a database in the middle of an rbu vacuum (which prevents the vacuum from resuming). check-in: 00b2f4b0 user: dan tags: rbu-vacuum
2016-04-18
21:00

16:12
Fix a problem in the code generator for joins on virtual tables where the outer loop of the join uses the IN operator. check-in: a2cf4968 user: drh tags: branch-3.12.0
16:06
Fix the sqlite3BtreeDelete() routine so that it preserves the correct key even when the row being deleted is not on a leaf page. Fix for ticket [a306e56ff68b8fa56] check-in: 368e86c7 user: drh tags: branch-3.12.0
15:59

13:09
The last parameter to pread64() and pwrite64() should be off64_t, not off_t. check-in: 3a7d7298 user: drh tags: trunk
09:17

Changes so that rbu vacuum works with zipvfs databases. check-in: bae7f875 user: dan tags: rbu-vacuum
17:53
Avoid creating any extra files ("<target>-vacuum") when running an RBU vacuum. Ensure that the OAL file created is "<target>-oal", not "<target>-vacuum-oal". check-in: dc19aacc user: dan tags: rbu-vacuum
15:03
Fix a couple of assert() statements that were failing with OOM error tests. check-in: 8eb3d7d8 user: dan tags: rbu-vacuum

16:27
Skip-ahead is now just an optimization. If it gets confused, it falls back to an incremental scan with redundancy elimination. check-in: 6fac0b92 user: drh tags: skip-ahead-distinct
16:17
Skip-ahead does not always work. So we still have to check for redundancy. check-in: db5a2364 user: drh tags: skip-ahead-distinct

CLI enhancement: Add the ".eqp full" option, that shows both the EXPLAIN QUERY PLAN and the EXPLAIN output for each command run. Also disable any ".wheretrace" and ".selecttrace" when showing EQP output. check-in: 3e217d62 user: drh tags: trunk
14:13
Several new test cases that cause failures. check-in: 0379f2cf user: drh tags: skip-ahead-distinct
13:24
Fixed crash bugs. Still sometimes gets the wrong answers. check-in: 2afcb2c7 user: drh tags: skip-ahead-distinct
01:55
Progress toward getting DISTINCT to use a seek to advance to the next distinct row, when driven by an appropriate index. check-in: 9e14aa14 user: drh tags: skip-ahead-distinct
2016-04-14
19:29

16:40
Add the SF_HasAgg constant (currently unused). Also enhance the comments on many other constant definitions to detail constraints on their values. check-in: 7b7a69d0 user: drh tags: trunk
15:44
Correctly interpret negative "PRAGMA cache_size" values when determining the cache-size used for sorting large amounts of data (i.e. the functionality in vdbesort.c). check-in: 79147dca user: dan tags: trunk
15:38
Add some missing testcase() macros to the pushDownWhereTerms() routine. check-in: 67d7f79c user: drh tags: trunk
13:35
Rename WhereInfo.pResultSet to pDistinctSet to more accurately reflect what it represents. check-in: 53179614 user: drh tags: trunk
13:16
Since the return value of sqlite3OsClose() is always ignored, we might as well make it "void" instead of "int", and thereby save 50 bytes in the compiled binary. check-in: 7ee570e7 user: drh tags: trunk
13:06
Additional ".selecttrace" debugging output when the query is transformed from a DISTINCT into a GROUP BY. check-in: 5a469145 user: drh tags: trunk
2016-04-13

17:13
Fix speedtest1 so that it automatically unlinks its test database prior to startup. check-in: b65b69f6 user: drh tags: trunk
