| 19:03 | Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. (Closed-Leaf check-in: 3a5860d86f user: drh tags: left-join-view) | |
| 17:30 | When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) (check-in: f489b5bb6b user: drh tags: trunk) | |
| 17:18 | An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. (check-in: 1838a59c8a user: drh tags: left-join-view) | |
| 14:50 | Make USE_FULLWARN=1 the default for MSVC and fix harmless compiler warnings. (check-in: 6bf673767b user: mistachkin tags: trunk) | |
| 14:02 | Enhance the sqlite3TreeView() display for Expr objects so that it shows the iRightJoinTable value for Expr nodes that have the EP_FromJoin property. (check-in: 5159cb8f2b user: drh tags: trunk) | |
| 12:39 | Simplify the interface to the subst() routines that are part of the query flattener by collecting common parameters into the SubstContext object and passing around a pointer to that object. (check-in: e651074be2 user: drh tags: trunk) | |
| 12:27 | Remove an incorrect ALWAYS(). (check-in: f956f6ae6b user: drh tags: trunk) | |

| 21:29 | Fix the skip-ahead-distinct optimization so that it works with indexes that have repeated columns with different collating sequences. (check-in: ce1e2b8877 user: drh tags: skip-ahead-distinct) | |
| 19:48 | Simplification of the skip-ahead-distinct logic. There is still an issue with handling COLLATE. (check-in: 57c5173b63 user: drh tags: skip-ahead-distinct) | |

| 15:51 | Reinstate the SQLITE_API qualifier on the sqlite3_delete_database() method in test_delete.c. Accidentally removed by the previous commit. (check-in: 59c70108fd user: dan tags: trunk) | |
| 15:36 | Update the code in test_delete.c to use the "win32" VFS if SQLITE_OS_WIN is defined. (check-in: fa9bb7b768 user: dan tags: trunk) | |
| 13:01 | Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. (check-in: 0cf16decd5 user: drh tags: skip-ahead-distinct) | |
| 09:45 | Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd151 user: dan tags: trunk) | |
| 01:19 | Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (check-in: 132339a1fb user: drh tags: skip-ahead-distinct) | |
| 00:12 | Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (check-in: 8e7b611863 user: drh tags: trunk) | |
|
2017-04-12
| ||

| 11:52 | Fix a segfault that could occur if an indexed expression was used in a comparison operation within the result-set of a SELECT statement. (check-in: d6bb7c42ff user: dan tags: trunk) | |
| 01:30 | When evaluating a query that uses an index on an expression, try to use the expression values read directly from the index rather than reevaluating the expression. (check-in: a47efb7c85 user: drh tags: trunk) | |
| 01:01 | Improved comments. Fix a problem when an indexed expression is used in an ORDER BY clause. (Closed-Leaf check-in: c59eaf2b7c user: drh tags: covering-index-on-expr) | |

| 14:11 | Expand on the comment above OP_Destroy to explain why it throws an error if there are any active reader VMs. (check-in: b9a8c2b9be user: dan tags: trunk) | |
| 13:52 | Have the rtree module close any open blob-handle within the xSavepoint method. This prevents such an open blob handle from interfering with DROP TABLE operations. (check-in: fa4416adc2 user: dan tags: trunk) | |
| 13:42 | Fix the quoting mechanism for ".dump" so that it is not applied for the ".mode quote" output. (check-in: 78c1e90305 user: drh tags: trunk) | |
| 09:12 | Have fts5 close any open blob-handle when a new savepoint is opened. This ensures that fts5 does not prevent DROP TABLE statements (which always open a savepoint) from succeeding. (check-in: a921ada890 user: dan tags: trunk) | |

| 23:08 | Fix an error in the newly revised documentation for SQLITE_LIMIT_VDBE_OP. No changes to code. (check-in: f4cf8635e6 user: drh tags: trunk) | |
| 22:51 | Set a reasonable limit on the number of opcodes in a prepared statement for ossfuzz.c. This should prevent timeouts in OSS-Fuzz when it generates totally unreasonable queries. (check-in: f74899ed2c user: drh tags: trunk) | |
| 22:50 | Begin enforcing the SQLITE_LIMIT_VDBE_OP. The documentation warned that this day might come. (check-in: ef59146170 user: drh tags: trunk) | |
| 14:59 | Add the --show-errors and --show-max-delay command-line options to the ossshell test program. (check-in: 626bdca98e user: drh tags: trunk) | |
| 14:15 | Fix the Makefile.in so that it builds the ossshell test program correctly. (check-in: 36f5602ec9 user: drh tags: trunk) | |
| 13:59 | Fix a buffer overread in debugging routine sqlite3VdbeMemPrettyPrint(). Problem discovered by OSS-Fuzz. (check-in: f336fba7d7 user: dan tags: trunk) | |
| 03:21 | Fix a problem in the enhanced PRAGMA integrity_check where it verifies CHECK constraints: Do not be confused by the reuse of the Table.pCheck field by VIEWs with named columns. Problem discovered by OSS-Fuzz. (check-in: 019dd3d5ba user: drh tags: trunk) | |

| 18:55 | If the user has not set it explicitly, set the "PRAGMA synchronous" setting to SQLITE_DEFAULT_SYNCHRONOUS when a database connection changes from wal to rollback journal mode. (check-in: 5c604479fd user: dan tags: trunk) | |
| 18:54 | Fix a typo causing the build to fail if SQLITE_DEFAULT_SYNCHRONOUS==SQLITE_DEFAULT_WAL_SYNCHRONOUS. (Closed-Leaf check-in: df39adeaa4 user: dan tags: default-synchronous-fix) | |
| 18:14 | If the user has not set it explicitly, set the "PRAGMA synchronous" setting to SQLITE_DEFAULT_SYNCHRONOUS when a database connection changes from wal to rollback journal mode. (check-in: 78030c0f52 user: dan tags: default-synchronous-fix) | |
| 14:28 | Simplified OOM detection in the instr() SQL function. (check-in: 6d85eb5736 user: drh tags: trunk) | |
| 13:30 | Fix an uninitialized variable reference in the text generator for "PRAGMA vdbe_trace=ON" output. Problem discovered by OSS-Fuzz. (check-in: e3d487162d user: drh tags: trunk) | |
| 13:14 | Fix a problem in the "showdb" utility that prevents it from correctly decoding cells with no content beyond the record header. (check-in: eb7680a1c0 user: drh tags: trunk) | |
| 12:11 | Fix a crash that could follow an OOM condition in the instr() SQL function. Problem discovered by OSS-Fuzz. (check-in: 6e59e903e4 user: dan tags: trunk) | |

| 20:27 | Updates to README files under the ext/ hierarchy. No changes to code. (check-in: 029bc5d224 user: drh tags: trunk) | |
| 19:11 | Add the "Obtaining The Code" subsection in the top-level README.md file. No changes to code. (check-in: b1b1aa8b69 user: drh tags: trunk) | |
| 14:20 | Mention the ".selftest" command in the ".help" output of the CLI. (check-in: 37f766dbad user: drh tags: trunk) | |
| 14:04 | Make "PRAGMA temp.synchronous=N" a no-op to ensure that the TEMP schema always has synchronous=OFF. This fixes an issue discovered by OSS-Fuzz. (check-in: bcf6bb08d8 user: drh tags: trunk) | |
| 13:47 | Improved header comment on the shathree.c extension. No changes to code. (check-in: 84f2e3d5f6 user: drh tags: trunk) | |

| 22:10 | Add the dbdump.c extension that implements functionality similar to the ".dump" command of the CLI, though in a separate library. (check-in: 2b9980a292 user: drh tags: trunk) | |
| 22:02 | Add dbdump.exe to the MSVC makefile. (Closed-Leaf check-in: 59241a50ad user: drh tags: dbdump) | |
| 21:49 | Fixes to the dump logic. All appears to be working in preliminary tests. (check-in: 007b11e301 user: drh tags: dbdump) | |
| 21:26 | First draft of the complete dbdump.c library. (check-in: 84ea4fcc52 user: drh tags: dbdump) | |
| 19:26 | Infrastructure for an extension C-library to implement sqlite3_db_dump() and a corresponding "dbdump" command-line utility - both of which do the same work as the ".dump" command of the CLI. (check-in: 74c5ace498 user: drh tags: dbdump) | |
| 18:31 | Merge all recent changes from trunk. (check-in: 3d04b2cd7a user: drh tags: apple-osx) | |
| 18:24 | In the output of the ".dump" command in the CLI, quote newline and carriage-return characters using the char() function, so that they do not get eaten by end-of-line processing logic in the OS or in other command-line utilities and/or libraries. (check-in: 68f6dc7af1 user: drh tags: trunk) | |
| 17:37 | Fix the sqlite3TreeViewSelect() routine so that it works with a null pointer to the Select object. (check-in: 9034cf7efc user: drh tags: trunk) | |
| 14:30 | Fix a segfault that could occur following an OOM error in the flattenSubquery() routine. (check-in: c6dda3f752 user: dan tags: trunk) | |
| 13:45 | In the OSSFuzz test module, invoke the progress handler much more frequently so that timeouts are detected punctually even if the test script is running opcodes that individually take a long time (for example, an OP_Function opcode that invokes "randomblob(1.5e6)"). (check-in: f3b6959c04 user: drh tags: trunk) | |

| 20:28 | Fix a possible NULL pointer dereference in following an OOM error in sqlite3ExprIsInteger(). Problem found by OSS-Fuzz. (check-in: 5ec655e8e8 user: drh tags: trunk) | |
| 19:39 | Remove an obsolete assert() in the IN operator code generation. (check-in: 18bf6aca2a user: drh tags: trunk) | |
|

| 13:02 | Make sure the translateColumnToCopy() routine in the query planner does not try to access an array that failed to be fully allocated due to a prior OOM. This fixes an issue discovered by OSSFuzz. (check-in: 3299a26160 user: drh tags: trunk) | |
| 01:56 | The output of the ".dump" command in the CLI quotes newline and carriage-return characters using "char(10)" and "char(13)". (Closed-Leaf check-in: 8b2954dd83 user: drh tags: string-quoting-dump) | |
| 00:46 | Increase the number of significant digits in floating point literals on ".dump" output from the shell. (check-in: 7359fcacaa user: drh tags: trunk) | |
|

| 18:36 | Remove the rbu_round_trip.tcl script. It is now part of project "test-dbs". (check-in: b5bf295767 user: dan tags: trunk) | |
| 17:03 | Fix an error in the SQLITE_MAX_MEMORY implementation resulting from a bad merge. Update the OSSFuzz interface so that it times out after running the byte-code engine for 10 seconds. (check-in: f8560c60d1 user: drh tags: trunk) | |
| 16:22 | Add the -DSQLITE_MAX_MEMORY=N compile-time option. The default is no limit. (check-in: eabd4ef498 user: drh tags: trunk) | |
| 15:55 | Add the SQLITE_MAX_MEMORY compile-time option that provides a hard upper bound on the amount of memory that SQLite will use, per process. (Closed-Leaf check-in: 77dfe2abda user: drh tags: max-memory-option) | |
| 14:36 | Enhance the ".stats" dot-command in the CLI to use sqlite3_status64() instead of sqlite3_status(). (check-in: 118f5c0564 user: drh tags: trunk) | |
| 01:05 | Improvements to ".selftest --init". Tests are number in increments of 10 starting with 100. The tests are generated inside a SAVEPOINT. Errors are reported during test generation. Tests can be appended to existing tests. Add a test case to verify the schema. (check-in: b044b152aa user: drh tags: trunk) | |

| 22:00 | Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old. (check-in: f4fcd46f08 user: drh tags: trunk) | |
| 18:13 | Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. (check-in: 6c627e5062 user: drh tags: trunk) | |
| 16:32 | Add the --recovery-mode option to the CLI ".dump" command. This involves enhancing the "PRAGMA reverse_unordered_selects" command to accept a "TOGGLE" option. Recovery mode used to be always on. Now it is opt-in. Not sure this is the correct approach. Also not sure if TOGGLE is a good feature to have on boolean PRAGMA statements. (Closed-Leaf check-in: 5dc82a155d user: drh tags: dump-recovery) | |
| 13:50 | Begin moving separate boolean variables in the ShellState object of the CLI into the shellFlgs bitmask. (check-in: 50eec5d9aa user: drh tags: trunk) | |

| 23:29 | Refactor the output logic in the CLI. Not sure we want to go this way. Just saving the work for historical reference, or in case I decide to come back to it. (Leaf check-in: aacac90663 user: drh tags: shell-print-refactor) | |
| 18:37 | Merge recent enhancements from trunk, including the --preserve-rowids option to .dump and the .sha3sum commands of the CLI. (check-in: 9b43917380 user: drh tags: apple-osx) | |
| 18:06 | Make sure the database connection is open prior to running the ".sha3sum" command. (check-in: 2ea300fb8f user: drh tags: trunk) | |
| 17:56 | In the ".sha3sum" command, if there is a LIKE pattern, show the hashes for each table separately. Without a LIKE pattern, show a single hash over the entire database. (check-in: 30f8788328 user: drh tags: trunk) | |
| 16:10 | Add the ".sha3sum" command to the CLI - used to compute a cryptographic hash of the content of a database file or of individual tables with in that file. (check-in: fc66379907 user: drh tags: trunk) | |
| 15:03 | Improved comments explaining the sha3_query() format. Fix a performance #ifdef error in the sha3 implementation. (check-in: 54ef7abd7f user: drh tags: trunk) | |
| 13:50 | Add the shathree.c extension for implementing SHA3() and SHA3_QUERY() SQL functions. (check-in: f7ca9193dd user: drh tags: trunk) | |
| 12:25 | In the CLI, avoid unnecessary identifier quoting in the ".dump" output. Also add new ".dump" test cases. (check-in: de65f90761 user: drh tags: trunk) | |
| 11:44 | Add the --preserve-rowids option to the ".dump" command in the CLI. (check-in: c60aee2471 user: drh tags: trunk) | |

| 20:03 | Add test script ext/rbu/rbu_round_trip.tcl. Uses "dbselftest" to test that "rbu" and "sqldiff" work together. (check-in: 961e79da73 user: dan tags: trunk) | |
| 14:47 | Before beginning an incremental checkpoint in RBU, sync the directory containing the target database file. This ensures that the new directory entry created by renaming the *-oal file to *-wal is synced to disk. Cherrypick of [915a9a28]. (Leaf check-in: 694fe0b22b user: dan tags: version-3.17.0-rbu-fixes) | |
| 14:46 | Fix another RBU case similar to the previous. This one for systems where the sector-size is larger than the page-size. Cherrypick of [4012bb3a]. (check-in: 59a11b7f1f user: dan tags: version-3.17.0-rbu-fixes) | |
| 14:45 | When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file. Otherwise, if a power failure occurs and the RBU update resumed following system recovery, the database may become corrupt. Cherrypick of [edee6a80]. (check-in: 811a559967 user: dan tags: version-3.17.0-rbu-fixes) | |
| 14:38 | Performance optimization in the tokenizer/parser loop. (check-in: 2cb71583d6 user: drh tags: trunk) | |
| 12:18 | Minor comment typo fixes. No changes to code. (check-in: 01cd9fb176 user: drh tags: trunk) | |
| 03:40 | More size and speed improvements in the expression name resolver. (check-in: e0a3d39f51 user: drh tags: trunk) | |
| 03:25 | Small size reduction and performance increase in the name resolver routine for expressions. (check-in: 1a3554e1d7 user: drh tags: trunk) | |

| 23:51 | Make the default MASK argument for "PRAGMA optimize" be 0xfffe, to allow for future expansion of up to 14 new default-on optimizations. (check-in: 73019a8bba user: drh tags: trunk) | |
| 20:44 | Fix a typo in a comment. No changes to code. (check-in: ec529bf11b user: drh tags: trunk) | |
| 20:00 | Merge all pending 3.18 enhancements from trunk. (check-in: 1650c3f468 user: drh tags: apple-osx) | |

| 21:51 | If a reprepare is needed after binding to a variable with a number larger than 32, set only the high-order bit of the Vdbe.expmask rather than setting all bits. This could potentially result in fewer false-positive reprepares. (check-in: 45797feefe user: drh tags: trunk) | |
