| 22:51 | Remove possibly stray output from various tests. (check-in: f38e0be56f user: mistachkin tags: testerOutput) | |
| 22:03 | Fix minor typo in the quicktest MSVC makefile target. (check-in: 75b65f9d49 user: mistachkin tags: trunk) | |
| 18:53 | "test" targets on all makefiles use --verbose=file --output=test-out.txt. Add the new "quicktest" target to all makefiles - designed to run in under three minutes. The --quick option on releasetest.tcl now uses quicktest. (check-in: 6ddef2ad35 user: drh tags: trunk) | |
| 14:27 | Avoid passing constraints that are unusable due to LEFT or CROSS joins to virtual table xBestIndex() methods. (check-in: 7b446771ca user: dan tags: trunk) | |
|

| 15:58 | Add the --output=$file and --verbose=(0|1|file) options to tester.tcl. (check-in: f7b2c70362 user: dan tags: trunk) | |
| 10:58 | Remove some repeated lines of source code. Probably introduced by careless cut'n'pasting. (Closed-Leaf check-in: a34cd71c8a user: dan tags: vtab-left-join) | |
|

| ||
| 19:15 | Add the valgrindfuzz target to unix makefile. (check-in: e62aed01f1 user: drh tags: trunk) | |
| 18:48 | If a query contains "FROM t1 LEFT JOIN t2, t3, t4", ensure that tables t3 and t4 are not scanned before t2. The trunk already does this. (check-in: 0d9edfab9f user: dan tags: vtab-left-join) | |
| 18:05 | Avoid passing constraints that are unusable due to LEFT or CROSS joins to virtual table xBestIndex() methods. (check-in: 80ee56dda7 user: dan tags: vtab-left-join) | |
| 17:42 | Fix typo in comment. No changes to code. (check-in: e49c291735 user: mistachkin tags: trunk) | |
| 17:40 | Split out some source code into new files: wherecode.c, whereexpr.c, and treeview.c. Other minor refactoring changes. (check-in: 50f336818c user: drh tags: trunk) | |
| 15:08 | Factor out the TreeView parse tree printing module into a separate file. (check-in: c32ce54ca4 user: drh tags: view-optimization) | |
| 14:23 | Split more subfunctions of where.c out into a new whereexpr.c source file, for improved maintainability. (check-in: 46ef95c108 user: drh tags: view-optimization) | |
|

| 20:12 | Split out the bulk of the actual VDBE code generation logic from where.c into a new file, leaving behind the analysis logic. This makes the original where.c smaller and hopefully easier to edit. (check-in: faa0e420e9 user: drh tags: view-optimization) | |
| 18:30 | Code simplifications in select.c and where.c. (check-in: 4f20ac90bc user: drh tags: view-optimization) | |
| 00:18 | Minor cleanup of the sqlite3Select() procedure. (check-in: f4c90d06bb user: drh tags: view-optimization) | |
|

| ||
| 22:33 | Split FROM-clause subquery flattening and code generation into separate loops. (check-in: be8e3fc70e user: drh tags: view-optimization) | |
| 20:27 | Provide one final Select tree dump prior to WHERE clause analysis when ".selecttrace 0x400" tracing bit is set with SELECTTRACE_ENABLED. Analysis and debug changes only - normal builds are unaffected. (check-in: 283bf0b64d user: drh tags: trunk) | |
|
2015-06-04
| ||
| 12:08 | Change the name of SrcList.a[].zIndex to the more descriptive SrcList.a[0].zIndexedBy. (check-in: 6a9cf06337 user: drh tags: trunk) | |

| 19:36 | Always check for cell overflow before returning a slot from the pageFindSlot routine in btree.c. (check-in: 9f035c45a4 user: drh tags: trunk) | |
| 18:09 | For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e949d user: drh tags: trunk) | |
| 17:25 | Add test cases for type affinity rules. (check-in: 9678646d9a user: drh tags: trunk) | |
| 16:19 | Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB to avoid confusion with "no affinity". (check-in: 29ad9e9173 user: drh tags: trunk) | |
| 15:32 | Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB. (Closed-Leaf check-in: bce3f04186 user: drh tags: blob-affinity-rename) | |
| 14:02 | Fix a faulty assert() in btree.c. Update the database fuzz test file with new test cases. (check-in: 4e621af134 user: drh tags: trunk) | |

| 18:13 | Corrections to comments in expr.c. No code changes. (check-in: f925389eaf user: drh tags: trunk) | |
| 11:10 | Typo fixes and additional background information in README.md. (check-in: 9b8e5823bc user: drh tags: trunk) | |

| 22:57 | Updates to configure.ac to help it find where the TCL libraries hidden on Ubuntu 14.04. (check-in: c864ff912d user: drh tags: trunk) | |
| 22:05 | Fix minor typo in comment. No changes to code. (check-in: 73fc058b3a user: mistachkin tags: trunk) | |

| 18:42 | Ensure that allocateBtreePage() always clears the MemPage pointer when it fails due to an I/O or memory allocation error. (check-in: 09a38bf665 user: drh tags: trunk) | |
| 17:51 | Move two unreachable conditionals inside of NEVER() or assert(). (check-in: db4e9728fa user: drh tags: trunk) | |
| 17:13 | Remove a corruption test in balance_nonroot that is superceded by a prior better check. (check-in: 00693682d8 user: drh tags: trunk) | |
| 15:15 | Omit the rowallock.test script (Read-Only WAL lock) from the inmemory_journal permutation. (check-in: d21db33089 user: drh tags: trunk) | |
| 14:47 | Add support for automatic indexes on FROM-clause subqueries that are implemented via co-routine. (check-in: 020b8b106f user: drh tags: trunk) | |
| 14:36 | Add some extra source-code comments and a test case. (Closed-Leaf check-in: 6d410442fb user: drh tags: coroutine-autoindex) | |
| 13:55 | An attempt to allow automatic index creation on subqueries accessed via co-routine. (check-in: 521345add6 user: drh tags: coroutine-autoindex) | |
| 01:35 | Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d7e user: drh tags: trunk) | |

| 15:14 | Added comments and testcase() macros to error cases in the btree search. (check-in: 7da7dc714b user: drh tags: trunk) | |
| 11:23 | Earlier detection of incompatible sibling pages in balance_nonroot. (check-in: 60a09f17d8 user: drh tags: trunk) | |
| 03:45 | Add new test cases to the fuzzdata3.db set of database fuzz tests. (check-in: 467b13a401 user: drh tags: trunk) | |
| 03:28 | Add the btreeGetUnusedPage() routine to btree.c, and use it to detect content pages on the freelist and to cause that condition to trigger an SQLITE_CORRUPT. (check-in: fe15d1f703 user: drh tags: trunk) | |
| 00:54 | Do not attempt to take any write lock on a read-only database on Windows. (check-in: a47ff0cdab user: drh tags: trunk) | |

| 19:35 | The fuzzoomtest makefile target is no longer supported, so update releasetest.tcl accordingly. (check-in: 06959d4ada user: drh tags: trunk) | |
| 18:19 | Fix a minor and harmless memory leak in fuzzcheck. Adjust the makefiles to run fuzzcheck with --quiet on valgrind tests. (check-in: 8bfe834432 user: drh tags: trunk) | |
| 18:13 | All bytes of a page are initialized, even bytes that follow a 2-byte cell on a malformed page. (check-in: 7373a004ed user: drh tags: trunk) | |
| 15:42 | A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (check-in: 95eaa49f4e user: drh tags: trunk) | |
| 15:10 | Disallow the use of "rowid" in CTEs - it has never worked correctly and it makes no sense, so we might as well make it an explicit error. Also: add the PRAGMA cell_size_check=ON command. (check-in: 19e2cebc12 user: drh tags: trunk) | |
| 14:21 | A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (Closed-Leaf check-in: 7e9e1b6123 user: dan tags: avoid-buffer-overread) | |
| 13:06 | CTEs have never had working rowids. So disallow the use of the "rowid" column within CTEs. (Closed-Leaf check-in: 0055df0445 user: drh tags: no-rowid-in-cte) | |
| 03:46 | Add the "PRAGMA cell_size_check=ON" command. (Closed-Leaf check-in: 2ead43f074 user: drh tags: cell-size-check-pragma) | |
