| 13:20 | New test case for the HAVING fix of check-in [f62f983b56623f0e]. (check-in: 45f46317 user: drh tags: trunk) | |
| 13:10 | New test cases for cursor renumbering in the UNION ALL query flattener. (check-in: 270babf2 user: drh tags: trunk) | |
| 13:04 | • Edit [5774318e7329ca47|5774318e]: Move to branch mistake. Mark "Closed". Edit check-in comment. (artifact: 6ae610af user: drh) | |

|
2020-12-29
| ||
| 16:48 | Add an ALWAYS on an always-true conditional in the cursor renumbering logic of the UNION ALL flattener. Edit: turns out this change is incorrect and the conditional is reachable after all. See the nearby trunk check-in for test cases. (Closed-Leaf check-in: 5774318e user: drh tags: mistake) | |
| 15:06 | Do not set the P3 parameter on OP_RowCell when copying an index btree, as P3 is not used in that case. (check-in: eef070a4 user: drh tags: trunk) | |
|
2020-12-28
| ||
| 21:42 | Fix missing comma in ctime.c that would cause the ENABLE_MATH_FUNCTIONS output rw to merge with whatever row followed. Problem reported in forum post aacac97680. (check-in: 328bc4a0 user: drh tags: trunk) | |
|
2020-12-22
| ||
| 14:54 | Simplification to the aggregate-function analysis error detection logic at the end of sqlite3Select(). (check-in: 82884438 user: drh tags: trunk) | |
|
2020-12-21
| ||
| 14:51 | Enhance documentation to show that "ro" is the correct way to say "readonly" in the mode= query parameter. (check-in: 788b9685 user: drh tags: trunk) | |
| 12:14 | Add the --timer option to fuzzcheck. Get the --timeout option working in fuzzcheck when running dbsql tests. (check-in: 3b0c9b41 user: drh tags: trunk) | |
|
2020-12-20
| ||
| 14:51 | Always declare the sqlite3WhereTrace variable, even for non-debug builds. (check-in: 88d93ee3 user: drh tags: trunk) | |
|
2020-12-19
| ||
| 13:58 | Allow UNION ALL sub-queries to be flattened even if the parent query is a join. (check-in: df1d6482 user: drh tags: trunk) | |
|
2020-12-17
| ||
| 15:17 | In the CLI, add the ".filectrl data_version" command. And put the various ".filectrl" subcommands in alphabetical order. (check-in: 34344521 user: drh tags: trunk) | |
|
2020-12-16
| ||
| 21:09 | Enhance the sqlite3BtreeTransferRow() routine so that it does more careful checks for corrupt database pages. (check-in: 85952e71 user: drh tags: trunk) | |
| 14:20 | Remove an unnecessary and incorrect #ifdef. Fix harmless compiler warnings. (check-in: 31cd1bbf user: drh tags: trunk) | |
| 13:20 | Fix a typo in the sqlite3_free_filename() documentation. (check-in: 7316ee19 user: drh tags: branch-3.34) | |
| 13:17 | Fix a typo in the sqlite3_free_filename() documentation. (check-in: 48301edc user: drh tags: trunk) | |
|
2020-12-14
| ||
| 16:50 | Merge the latest trunk enhancements into the begin-concurrent-pnu branch. (check-in: daf04650 user: drh tags: begin-concurrent-pnu) | |
| 16:26 | Merge recent trunk enhancements into the begin-concurrent branch. (check-in: a1708e84 user: drh tags: begin-concurrent) | |
| 15:39 | Enhance UPSERT so that it allows multiple ON CONFLICT clauses and does not require a conflict target for DO UPDATE. (check-in: 6b01a24d user: drh tags: trunk) | |
| 13:52 | Minor changes for test coverage. (Closed-Leaf check-in: e5a8fa50 user: drh tags: generalized-upsert) | |
|
2020-12-12
| ||
| 00:43 | More test cases. No new problems discovered. (check-in: f34dd67e user: drh tags: generalized-upsert) | |
| 00:28 | New test cases with corresponding bug fixes. (check-in: f22c21a9 user: drh tags: generalized-upsert) | |
|
2020-12-11
| ||
| 19:36 | Begin adding test cases. Fix one bug found so far. More are pending. (check-in: aadd67dd user: drh tags: generalized-upsert) | |
| 17:11 | Small performance tweaks. (check-in: 5321d60c user: drh tags: generalized-upsert) | |
| 16:49 | Bug fixes so that legacy tests pass. New tests for new functionality have not yet been added. (check-in: aa76790e user: drh tags: generalized-upsert) | |
| 14:34 | Fix the configure script on the autoconf distribution so that the --disable-threadsafe option works. See FreeBSD bug 244459. (check-in: e64ff2cc user: drh tags: trunk) | |
| 01:17 | Logic is in place to handle multiple ON CONFLICT clauses, but it does not work. Any use of ON CONFLICT will likely lead to memory faults. This is an incremental check-in to save my place. (check-in: 15514231 user: drh tags: generalized-upsert) | |
|
2020-12-10
| ||
| 20:31 | Use an iterator for the index loop in sqlite3GenerateConstraintChecks(). The idea is that this iterator can be enhanced to traverse the indexes in any order, as required by multi-index UPSERT. (check-in: 64a4a91e user: drh tags: generalized-upsert) | |
| 13:49 | Add an optional function to the chsumvfs extension. When activated by the SQLITE_CKSUMVFS_INIT_FUNCNAME macro, this function will invoke the file-control that sets the number of reserved bytes to 8. This can be used to initialize a cksumvfs database file by programming languages that do not have access to the sqlite3_file_control() interface. (check-in: 01841fb4 user: drh tags: trunk) | |
| 12:49 | The DO UPDATE code generator searches for the correct ON CONFLICT clause to use. (check-in: a47e35ee user: drh tags: generalized-upsert) | |
| 11:38 | • Edit [3194c00c2c6a32bd|3194c00c]: Move to branch generalized-upsert. (artifact: 5e906933 user: drh) | |
|
2020-12-09
| ||
| 20:30 | For upsert, the constraint check code generator uses a copy of the index list for the target table, which can potentially be reordered. (check-in: 3194c00c user: drh tags: generalized-upsert) | |
| 13:11 | Improved comments in sqliteInt.h. No changes to code. (check-in: 8ccb8d1d user: drh tags: generalized-upsert) | |
| 01:34 | Initialize all terms in the ON CONFLICT clause stack. (check-in: 5e683fd1 user: drh tags: generalized-upsert) | |
|
2020-12-08
| ||
| 21:14 | • Changes to wiki page "StrictMode" (artifact: e444a88b user: drh) | |
| 21:00 | • Changes to wiki page "StrictMode" (artifact: 7fbb9eea user: drh) | |
| 14:29 | Enhance UPSERT parsing to allow multiple ON CONFLICT clauses. Only the very last clause may omit the conflict target, but the conflict target may now be omitted for the DO UPDATE resolution. (check-in: 2ca62f4c user: drh tags: generalized-upsert) | |
|
2020-12-07
| ||
| 23:14 | Fix a bad assert() in math1Func(). (check-in: 4b286129 user: drh tags: trunk) | |
| 21:19 | Fix to the --disable-math option to ./configure. (check-in: 99ff6418 user: drh tags: trunk) | |
| 21:13 | Many more math functions. Semantics follows PG wherever possible. (check-in: 6b93627b user: drh tags: trunk) | |
| 17:15 | Begin adding new SQL functions that depend on -lm: ceil(), ceiling(), floor(), ln(), log(), and log10() so far. More to follow. (check-in: 4db5f2f7 user: drh tags: trunk) | |
|
2020-12-04
| ||
| 17:05 | Fix harmless compiler warnings associated with the recent FTS5 enhancements. (check-in: 1db7c751 user: drh tags: trunk) | |
| 16:58 | Fix a bug in the ".eqp" command of the shell that was introduced by the recent sqlite3SelectTrace/SQLITE_TESTCTRL_TRACEFLAGS changes. (check-in: fd02dffc user: drh tags: trunk) | |
| 16:25 | Fix an incorrect datatype no the sqlite3WhereTrace variable in test1.c. (check-in: 4e6dab30 user: drh tags: trunk) | |
| 16:09 | Eliminate the sqlite3_unsupported_selecttrace global variable by creating a new test-control to control SELECT tracing. Note that SELECT tracing is only available on debug builds. (check-in: fb07c4e3 user: drh tags: trunk) | |
| 16:04 | Further changes to the trace variables to try to eliminate (harmless) compiler warnings in all configurations. (Closed-Leaf check-in: 3a4c98b9 user: drh tags: traceflags-test-control) | |
| 01:17 | Alternative implementation of ".selecttrace" and ".wheretrace" that uses a test-control rather than global variables. (check-in: d36d6f29 user: drh tags: traceflags-test-control) | |
|
2020-12-03
| ||
| 19:25 | Do not simulate OOM faults on the SQLITE_FCNTL_CKPT_START and SQLITE_FCNTL_CKPT_DONE file-controls, as those are write-only and the return value is always ignored. (check-in: 62a2d394 user: drh tags: trunk) | |
| 14:21 | Enhance the generate_series() table-valued function to support negative step values. (check-in: 9b60fc48 user: drh tags: trunk) | |
|
2020-12-02
| ||
| 20:52 | • Changes to wiki page "StrictMode" (artifact: 6a4d4273 user: drh) | |
| 20:39 | • Changes to wiki page "ToDo" (artifact: 09d9dbe6 user: drh) | |
| 18:27 | Fix the ".open" command in the CLI so that it accepts command-line options both before and after the filename. (check-in: d330bf0c user: drh tags: trunk) | |
| 02:58 | Parameterize the hash function in mkkeywordhash.c. This was an attempt to find a better hash function, which turned out to not be successful. (check-in: 2195d731 user: drh tags: trunk) | |
| 00:22 | Increase the version number to 3.35.0 to begin the next development cycle. (check-in: edbabaa3 user: drh tags: trunk) | |
| 00:20 | Slightly faster tokenization of non-keyword identifiers. (check-in: 55fa22bd user: drh tags: trunk) | |
|
