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

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.

20:58
Add tests for creating temp schema objects with SQLITE_OPEN_REUSE_SCHEMA connections. check-in: 8c07b609fc user: dan tags: reuse-schema

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

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
2019-02-07

00:17
In the fuzzcheck test program, make sure the isspace() and related routines are not given values outside the range of -1 to 255. check-in: f298328771 user: drh tags: trunk
2019-02-06
20:49
Ensure all bytes of the PgHdr1 structure are initialized. This avoids a valgrind error when running corruptI.test. check-in: a505e34d4e user: dan tags: trunk
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. check-in: 0e6249cb95 user: dan tags: trunk
