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)
15:26
Fix a problem in rbu vacuum on tables with a large sqlite_master table. (check-in: 23eac52e user: dan tags: rbu-vacuum)
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
When an error occurs while transitioning out of WAL mode, make sure the locking state is not left at EXCLUSIVE. (check-in: 3340f086 user: drh tags: trunk)
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)
17:47
Add fault injection tests for rbu vacuum. Fix some problems revealed by the same. (check-in: f042fdd1 user: dan tags: rbu-vacuum)
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
Another fix to rbu vacuum for a zipvfs case. (check-in: 29407d70 user: dan tags: rbu-vacuum)
18:18
Fix some zipvfs related problems in RBU vacuum. (check-in: d76f4aaa user: dan tags: rbu-vacuum)
15:46
Remove quotes from identifiers used as datatype names in a CREATE TABLE statement. Fix for ticket [7d7525cb01b68] (check-in: eba27d4d user: drh tags: trunk)
13:36
Merge recent trunk changes. (check-in: d9768de5 user: drh tags: tempfiles-25)
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
Add the -vacuum switch to the "rbu" demonstration program. (check-in: 9a0078a5 user: dan tags: rbu-vacuum)
2016-04-16
19:02
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)
2016-04-15
20:46
Add the experimental sqlite3rbu_vacuum() API function. For opening an RBU handle that rebuilds a database from scratch. (check-in: 0216b48f 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)
15:54
Fixes to the skip-ahead distinct logic. More issues remain. (check-in: 45a70b2b user: drh tags: skip-ahead-distinct)
15:06
Merge enhancements from trunk, especially the ".eqp full" enhancement to the command-line shell. (check-in: 491f0dbd user: drh tags: skip-ahead-distinct)
15:03
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
Work toward improving analysis and code generation for DISTINCT and aggregate queries. (Leaf check-in: 129083bd user: drh tags: better-distinct-agg)
17:29
In the ICU extension toupper() and tolower() SQL functions, avoid calling u_strToUpper() or u_strToLower() a second time if the buffer passed to the first invocation turns out to be large enough. (check-in: d23e5813 user: dan tags: trunk)
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)
