Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. check-in: ba0ab042f4 user: dan tags: reuse-schema
17:36
Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. check-in: 9a78d89c84 user: dan tags: reuse-schema
2019-02-19
18:00
Improve error messages caused by corrupt database schemas in OPEN_SHARED_SCHEMA mode. check-in: 8ac75b8a88 user: dan tags: reuse-schema
2019-02-18
18:16
Ensure that creating temp schema items does not cause an OPEN_SHARABLE_SCHEMA connection to load all schemas into memory. check-in: 88cbf54eee user: dan tags: reuse-schema
2019-02-15
19:36
Enhance the virtual table in test_schemapool.c so that it can be used to check that SHARED_SCHEMA connections are not allocating and freeing schemas when they should not be. check-in: cb236cb985 user: dan tags: reuse-schema
19:00
Fix a problem with eponymous virtual tables and SHARED_SCHEMA databases. Also, after preparing statements that require all database schemas (REINDEX, ANALYZE, CREATE, DROP and some PRAGMA statements), do not allow the database connection to return more than one schema to each schema-pool. check-in: ecf6251ec0 user: dan tags: reuse-schema
11:54
Revert the rearrangement of VDBE code in [219b39e14] so that vdbe.c matches trunk. Since the new call to sqlite3Init() in OP_ParseSchema was removed, the rearrangement no longer provides any performance advantage. check-in: 03c4f00317 user: dan tags: reuse-schema
2019-02-14
21:04
Fix SQLITE_DBSTATUS_SCHEMA_USED so that it works with SQLITE_OPEN_SHARED_SCHEMA connections. check-in: d43b3c056c user: dan tags: reuse-schema

15:56
Merge latest trunk into this branch. check-in: 577d163836 user: dan tags: reuse-schema
15:47
Add missing comments and fix other code issues in the new functions in callback.c. check-in: 441cabb62f user: dan tags: reuse-schema
15:27
Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). check-in: aa61435a4c user: drh tags: trunk
2019-02-13
19:17
Fix for sqlite3_table_column_metadata() on REUSE_SCHEMA databases. check-in: 53220ad780 user: dan tags: reuse-schema
18:29
Avoid crashing after parsing a corrupt schema with a REUSE_SCHEMA connection. check-in: b102148e71 user: dan tags: reuse-schema
15:51
Fix a problem with the incrblob API and reusable schemas. check-in: 34f0f96f47 user: dan tags: reuse-schema
14:06
Rearrange the code in the VDBE to help out the C-compiler optimizer. And fix a harmless compiler warning. check-in: 219b39e149 user: drh tags: reuse-schema
13:48
Performance optimization in the VDBE, and a fix for a harmless compiler warning. Closed-Leaf check-in: e002666ac7 user: drh tags: reuse-schema-vdbe-opt
08:40
Fix a problem with OPEN_REUSE_SCHEMA connections reloading the temp schema. check-in: 7c2ec2d4cf user: dan tags: reuse-schema
2019-02-12
22:58
Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. check-in: 167b91df77 user: drh tags: trunk
21:04
Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. check-in: 68cce272e7 user: drh tags: trunk
20:58
Add tests for creating temp schema objects with SQLITE_OPEN_REUSE_SCHEMA connections. check-in: 8c07b609fc user: dan tags: reuse-schema
19:20
Share schemas between databases attached to the same database handle. check-in: ea611d7cba user: dan tags: reuse-schema
16:58
Further performance improvements to btreeInitPage(). check-in: 93ae382e97 user: drh tags: trunk
15:51
Increase the version number to 3.28.0 for the next release cycle. check-in: 6eb38c59a8 user: drh tags: trunk
12:25
Register the "vfsstat" virtual table immediately when loading the vfsstat.c extension. check-in: 9bd92afd0c user: drh tags: trunk
01:28
New test cases in test/fuzzdata8.db. check-in: ab2356f580 user: drh tags: trunk
01:04
Defer computing the number of bytes of free space on a btree page until that value is actually needed. check-in: 177f5f40ea user: drh tags: trunk
00:58
Change an assert() into a NEVER(), since the condition is difficult to prove with certainty. Improved comment on the MemPage.nFree field. Closed-Leaf check-in: fec071b89d user: drh tags: deferred-free-space
2019-02-11
22:50
Do not invoke btreeComputeFreeSpace() when not necessary. check-in: f11b0ed474 user: drh tags: deferred-free-space
20:13
Merge latest trunk changes into this branch. check-in: dbedd81bf2 user: dan tags: reuse-schema
19:34
Add eponymous virtual table "schemapool". For inspecting the current contents of the schema-pool. check-in: 2ebeb74783 user: dan tags: reuse-schema
19:27
Improvements to comments. No changes to code. check-in: 16eb0fc8f8 user: drh tags: deferred-free-space
17:22
Fix test cases. Avoid unnecessary tests for MemPage.nFree less than zero. check-in: 480a5090be user: drh tags: deferred-free-space
16:12
Fix another segfault that could occur in fts5 with a corrupted database. check-in: 09e337386b user: dan tags: trunk
13:25
Fix typos in comments in fts5.h. No changes to code. check-in: c19e97bc92 user: dan tags: trunk
12:51
Updates to a comment to keep it in alignment to the changes on this branch. check-in: 7499f74351 user: drh tags: deferred-free-space
11:34
Build and test fixes for SQLITE_OMIT_WINDOWFUNC builds. check-in: 8824115a97 user: dan tags: trunk
11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. check-in: 4a4952d38e user: dan tags: trunk
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. check-in: 7b41222428 user: drh tags: trunk
2019-02-09
22:33
Fix a page-cache reference leak in the btree balancer when there is a corrupt database. check-in: 9285899120 user: drh tags: deferred-free-space
21:06
Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. check-in: 1d43ee4000 user: drh tags: deferred-free-space
19:23
Change a few assert() statements in fts3 that might fail if the database is corrupt. check-in: db74a56af7 user: dan tags: trunk
17:47
Fix virtual table support for SQLITE_OPEN_REUSABLE_SCHEMA connections. check-in: 3ca8856a7b user: dan tags: reuse-schema
2019-02-08
22:34
Small performance improvement and size reduction for pageFindSlot() - the routine in btree.c that locates a free slot for a cell on a btree page. check-in: 1969372ac7 user: drh tags: trunk
19:30
Add test cases and fix problems on this branch. check-in: 2b2e9f81cd user: dan tags: reuse-schema
17:28
Further simplifications to sqlite3VdbeMemSetStr(). check-in: 1d21295707 user: drh tags: trunk
15:59
Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. check-in: 5c499da8a4 user: drh tags: trunk
14:55
Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. check-in: 5c6638040b user: drh tags: trunk
04:15
Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. check-in: 440a7cda00 user: drh tags: trunk
