03:52
Remove an unnecessary conditional from the sqlite3DecOrHexToI64() routine. check-in: fcf85bfe user: drh tags: trunk
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
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
02:35
Remove still more unnecessary branches from sqlite3AtoF(). check-in: 3adfe9f3 user: drh tags: trunk
2016-04-26
23:14
Further simplifications to sqlite3AtoF() to remove unneeded branches. check-in: dd69e53c user: drh tags: trunk
21:02
Remove an unnecessary line from the sqlite3AtoF() routine. check-in: a9d00749 user: drh tags: trunk
18:58
The pcache and the built-in VFSes should not use mutexes when SQLITE_CONFIG_SINGLETHREAD is set. check-in: 12418b10 user: drh tags: trunk
13:13
Fix the "checksymbols" target in Makefile.in to be able to deal with the sqlite3changegroup family of interfaces. check-in: d819bfbd user: drh tags: trunk
2016-04-25
19:25
Update the RBU vacuum code so that databases that use custom collation sequences can be vacuumed. check-in: 7dd48c10 user: dan tags: trunk
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
2016-04-23
20:59
Fix the fix to the temporary directory search algorithm so that it continues to return "." as a fallback if that directory has the correct permissions. check-in: b38fe522 user: drh tags: trunk
2016-04-21
23:37
Change the temporary directory search algorithm on unix so that directories with only -wx permission are allowed. And do not allow "." to be returned if it lacks -wx permission. check-in: 67985761 user: drh 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
15:26
Fix a problem in rbu vacuum on tables with a large sqlite_master table. check-in: 23eac52e user: dan tags: rbu-vacuum
02:27
Add the SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION method for enabling sqlite3_load_extension() while leaving the load_extension() SQL function disabled. check-in: c4f165c4 user: drh tags: trunk
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

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

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

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
2016-04-14
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
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
