27 check-ins using file src/sqliteInt.h version 29ac7a59

2018-09-27
17:33
Another minor tweak to memstat.c so that it may be built against older versions of SQLite. (check-in: 4c1fed60 user: dan tags: trunk)
17:15
Modify the memstat virtual table so that it works with SQLite version 3.9.2. (check-in: 7171d8ae user: drh tags: trunk)
17:03
Add the sqlite_memstat extension - an eponymous virtual table that shows memory usages statistics for SQLite. (check-in: 954ef61f user: drh tags: trunk)
16:57
Enhancements to sqlite_memstat: (1) Add an extra "schema" column to show the schema name for ZIPVFS stats. (2) Only show ZIPVFS stats to schema that use ZIPVFS (3) Put a NULL in unused columns of the output. (Closed-Leaf check-in: 9351135b user: drh tags: memstat-vtab)
15:45
Add initial ZIPVFS support for the "main" database to the sqlite_memstat virtual table. (check-in: 9cd27350 user: drh tags: memstat-vtab)
15:21
Initial prototype of a eponymous virtual table that accesses sqlite3_status64() and sqlite3_db_status(). (check-in: 0b44e1f6 user: drh tags: memstat-vtab)
14:24
Minor enhancement to the pager so that it remembers if the underlying database files is immutable. (Leaf check-in: 64db614e user: drh tags: immutable-pager)
12:14
Disallow the use of window functions in the recursive part of a recursive CTE. Fix for ticket [e8275b415a2f03bee]. (check-in: 7fc29944 user: dan tags: trunk)
00:04
Minor simplification: In OP_ParseSchema, read the p1 register once. (check-in: bd250533 user: mistachkin tags: trunk)
2018-09-26
18:02
Further improvements to the ".help" command in the CLI. (check-in: edc3d18e user: drh tags: trunk)
16:53
Begin revamping the ".help" command in the command-line shell so that it can accept an argument and will do a search for commands that match that argument. (check-in: 209afb8d user: drh tags: trunk)
16:05
Tweak spellfix.c so that if SQLITE_SPELLFIX_5BYTE_MAPPINGS is defined at compile time the Transliteration structure has space for 5 byte (instead of 4 byte) mappings. (check-in: cbaf5b6c user: dan tags: trunk)
03:43
Fix typos in the header comment for the sha1 and sha3 hash extensions in the ext/misc folder. (check-in: 4ed9d83a user: drh tags: trunk)
2018-09-25
13:51
Fix a problem in releasetest.tcl causing configuration "Fast-One" to fail. (check-in: 42e04fef user: dan tags: trunk)
2018-09-24
15:39
Slightly smaller and faster alternative to [507d892c3a40a0bacbd47] that fixes a problem with views that use window function as part of complex expressions. (check-in: d7c816ae user: drh tags: trunk)
14:51
Fix a problem with views that use window functions as part of complex expressions. (check-in: 507d892c user: dan tags: trunk)
14:10
Allow a writable virtual table to have a schema with an INTEGER PRIMARY KEY and WITHOUT ROWID. This fixes ticket [f25d5ceebe1d710ff61a571e395356869d8272ef]. Test case in TH3. (check-in: 5a38d928 user: drh tags: trunk)
12:37
Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. (check-in: 903e5018 user: drh tags: trunk)
10:47
Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. (check-in: 3dd35f51 user: drh tags: trunk)
2018-09-23
02:01
Fix a faulty assert() in the validation logic for the LEFT JOIN strength reduction optimization. Problem found by OSSFuzz. (check-in: 2fd62fcc user: drh tags: trunk)
2018-09-22
15:05
Enhance WhereLoopBuilder.iPlanLimit to handle a case involving the OR optimization discovered overnight by OSSFuzz. (check-in: 7b59930a user: drh tags: trunk)
2018-09-21
23:41
Fix harmless compiler warning when compiled with SQLITE_OMIT_AUTHORIZATION. (check-in: 50f2fa19 user: mistachkin tags: trunk)
19:06
Comment typo fixed. No code changes. (check-in: 7e68cdab user: drh tags: trunk)
18:43
Put a limit counter on the query planner that restricts the number of index+constraint options that can be considered for each table in a join. This prevents certain pathological queries from taking up too much time in the query planner. (check-in: 8690b5a0 user: drh tags: trunk)
13:07
Optimization to the OP_MakeRecord opcode makes speed-check.sh run about 1.1 million cycles faster, and results in a slightly smaller library. (check-in: d10e6362 user: drh tags: trunk)
2018-09-20
20:43
Minor code simplification. (check-in: 22ae8a52 user: drh tags: trunk)
20:15
Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. (check-in: 7edd26ed user: drh tags: trunk)
