2019-02-25
14:25
Fix a typo in the documentation for sqlite3_total_changes(). check-in: 4febdfb37b user: drh tags: branch-3.27
14:16
Fix a typo in the documentation for sqlite3_total_changes(). check-in: 8474c1560e user: drh tags: trunk
2019-02-23
20:48
Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. check-in: 84162af521 user: dan tags: trunk
00:56
Import from trunk the new fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. check-in: 0e64ac122a user: drh tags: branch-3.27
00:21
Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. check-in: d3915230e3 user: drh tags: trunk
00:08
Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. Closed-Leaf check-in: 90c5a17cd5 user: drh tags: tkt-df46dfb631
2019-02-22
23:29
Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. check-in: c2d50df8fd user: drh tags: tkt-df46dfb631
21:33
Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. check-in: 0d456456da user: drh tags: tkt-df46dfb631
19:24
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. check-in: 579b66eaa0 user: dan tags: trunk
17:44
Merge latest trunk changes into this branch. check-in: 001771afd0 user: dan tags: reuse-schema
16:18
In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. check-in: 73056b314b user: drh tags: trunk
15:42
Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. check-in: e7144ffd21 user: drh tags: trunk
2019-02-21
18:11
Fix OOM handling in sqlite3NestedParse(). Leaf check-in: e6e9dd5c17 user: dan tags: nested-parse-oom
16:41
Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. check-in: c13d563925 user: drh tags: trunk
2019-02-20
19:20
Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. check-in: be21a6416d user: drh tags: trunk
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. check-in: af84774d1e user: drh tags: trunk
18:44
Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. check-in: ba0ab042f4 user: dan tags: reuse-schema
18:13
Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. check-in: c48f6f39c5 user: drh tags: trunk
17:36
Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. check-in: 9a78d89c84 user: dan tags: reuse-schema
13:55
Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. check-in: 0c5db18d79 user: drh tags: trunk
13:23
Merge the latest performance enhancements and fixes from trunk. check-in: be71d1e24c user: drh tags: apple-osx
13:14
Increment the version number to 3.27.2. check-in: a70d67d8af user: drh tags: branch-3.27
13:12
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. check-in: 55e38d53ad user: drh tags: branch-3.27
12:52
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. check-in: fa792714ae user: drh tags: trunk
03:38
Back off the optimization of check-in [e130319317e76119] slightly so that it only applies to IN operators that are used for membership tests. Proposed fix for ticket [df46dfb631f75694]. Closed-Leaf check-in: b5f90bfe62 user: drh tags: tkt-df46dfb631
2019-02-19
20:29
Enhance the xBestIndex method on delta_parse() to return SQLITE_CONSTRAINT if no delta argument is supplied. check-in: f16d127c3b user: drh tags: trunk
20:19
Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc267b user: drh tags: trunk
18:39
Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. check-in: b80cafa6f8 user: drh tags: trunk
18:00
Improve error messages caused by corrupt database schemas in OPEN_SHARED_SCHEMA mode. check-in: 8ac75b8a88 user: dan tags: reuse-schema
17:45
Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. check-in: 12517d1b15 user: drh tags: trunk
16:42
Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db4d user: drh tags: trunk
13:51
New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a7a user: drh tags: trunk
13:08
Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. check-in: 55d43adc89 user: drh tags: trunk
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
12:16
Fix an assert() that might not be true if the %_segdir table of FTS3 contains corrupt entries. check-in: a6509ca3dc user: drh tags: trunk
2019-02-16
22:45
Fix an assert() that might be false for a corrupt database. check-in: 0cfb888723 user: drh tags: trunk
17:27
Add support for chaining of WINDOW definitions. check-in: c155125fd5 user: dan tags: window-functions
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
18:38
Change the name of the SQLITE_OPEN_REUSE_SCHEMA flag to SQLITE_OPEN_SHARED_SCHEMA. check-in: 7257fcc8c9 user: dan tags: reuse-schema
17:59
Fix a typo in shared_schema.md. check-in: e47a5aea76 user: dan tags: reuse-schema
17:51
Add documentation file doc/shared_schema.md to describe the change on this branch. check-in: a5f8067dde 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
