| 19:16 | Reformat the white-space in a few test cases so that the tests work with Tcl 8.6.9. (check-in: 29d02bf2fa user: dan tags: trunk) | |
| 18:21 | Minor change to dbfuzz2 that allows it to be compiled against older versions of SQLite. (check-in: 6d39d6a68b user: drh tags: trunk) | |
| 17:52 | New test cases added to test/fuzzdata8.db. (check-in: 61fdfc57b9 user: drh tags: trunk) | |
| 17:49 | Allocate a few extra bytes for the pager temp page as an overrun buffer while processing corrupt database files. (check-in: e7aca0714b user: drh tags: trunk) | |
| 16:36 | Update doc/shared_schema.md to describe the shell tool ".shared-schema" dot-command. (check-in: 0ce2092a59 user: dan tags: reuse-schema) | |
| 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: 05b87e0755 user: drh tags: trunk) | |
| 16:13 | Add new test file reuse5.test. For testing the shell tool ".shared-schema" command. (check-in: fa6008d547 user: dan tags: reuse-schema) | |
| 16:11 | Fix a harmless compiler warning that only comes up during debug builds. (check-in: 848869ced9 user: drh tags: trunk) | |
| 15:43 | Add the ".shared-schema check|fix DB1 DB2..." command to the shell tool. For checking if a database is eligible to share an in-memory with the main database, and for fixing small problems that prevent it from being so. (check-in: 7d8e8a9572 user: dan tags: reuse-schema) | |

| ||
| 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) | |
| 00:21 | 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) | |

| 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) | |
| 18:13 | 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) | |
| 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) | |
| 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) | |

| 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) | |
| 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) | |

| 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) | |
| 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) | |

| 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) | |

| 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) | |

| 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) | |
| 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.
