Remove some stale references to the addopcodes.tcl script from documentation. check-in: c0381b0b user: drh tags: trunk
20:56
Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space.

17:45
Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. check-in: bc0fb1c3 user: drh tags: trunk
17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization.

Add an "|| CORRUPT_DB" term to an assert() statement in the btree defragmenter. check-in: 6bfd8655 user: drh tags: trunk

Enable the LIKE optimization when the ESCAPE keyword is present and the PRAGMA case_sensitive_like pragma is ON. check-in: 6ae4b8c5 user: drh tags: trunk

Fix the readfile() UDF so that it returns an empty BLOB, not an OOM error, when reading an empty file. check-in: 0edad533 user: drh tags: trunk

Add the "-returntype" option to the "db function" Tcl method. check-in: 789a492b user: dan tags: trunk

New test cases added to test/fuzzdata8.db. check-in: 61fdfc57 user: drh tags: trunk

16:17
Use unsigned integers to count the number of pages in a freelist during an integrity_check, to avoid any possibility of a signed integer overflow. check-in: 05b87e07 user: drh tags: trunk

Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. check-in: 84162af5 user: dan tags: trunk
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: d3915230 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: 90c5a17c 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: c2d50df8 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: 0d456456 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: 579b66ea user: dan tags: trunk
16:18
In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. check-in: 73056b31 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: e7144ffd user: drh tags: trunk
2019-02-21
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: c13d5639 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: be21a641 user: drh tags: trunk
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. check-in: af84774d user: drh tags: trunk
18:13
Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. check-in: c48f6f39 user: drh tags: trunk
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: 0c5db18d user: drh tags: trunk
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: fa792714 user: drh tags: trunk
2019-02-19

Enhance the xBestIndex method on delta_parse() to return SQLITE_CONSTRAINT if no delta argument is supplied. check-in: f16d127c user: drh tags: trunk
20:19
Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc26 user: drh tags: trunk
18:39
Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. check-in: b80cafa6 user: drh tags: trunk
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: 12517d1b user: drh tags: trunk
16:42
Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db user: drh tags: trunk
13:51
New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a user: drh tags: trunk

Fix an assert() that might be false for a corrupt database. check-in: 0cfb8887 user: drh tags: trunk

Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. check-in: 167b91df 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: 68cce272 user: drh tags: trunk
16:58
Further performance improvements to btreeInitPage(). check-in: 93ae382e user: drh tags: trunk

Defer computing the number of bytes of free space on a btree page until that value is actually needed. check-in: 177f5f40 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: fec071b8 user: drh tags: deferred-free-space
2019-02-11
22:50
Do not invoke btreeComputeFreeSpace() when not necessary. check-in: f11b0ed4 user: drh tags: deferred-free-space

Improvements to comments. No changes to code. check-in: 16eb0fc8 user: drh tags: deferred-free-space
