| 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) | |

(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) | |

|
2017-03-11
| ||
| 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) | |
|
2017-03-10
| ||
| 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) | |
|
2017-03-09
| ||
| 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) | |
|
2017-03-08
| ||
| 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) | |

| 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) | |

| 14:45 | When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file.

| 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) | |
| 21:36 | Remove an redundant function call from the date/time function implementation. (check-in: 4a04c48a31 user: drh tags: trunk) | |

| 19:43 | List of MATCH operator names in isMatchOfColumn() should be constant. (check-in: 7319d676aa user: drh tags: trunk) | |
| 18:56 | Performance enhancement in the expression walker. (check-in: ebccbd9609 user: drh tags: trunk) | |
| 15:02 | Tweaks to pcache1TruncateUnsafe() to make it slightly smaller and faster and easier to test. (check-in: 059f4e2efe user: drh tags: trunk) | |
| 14:40 | Rearrange the code inside sqlite3RunParser() routine so that sqlite3Parser() is only called from a single place. This allows sqlite3Parser() to be in-lined, which results in a 0.25% overall performance gain. (check-in: 25d1d02b3e user: drh tags: trunk) | |
| 13:34 | Increment the version number to 3.15. (check-in: 8c2701e70a user: drh tags: trunk) | |
| 13:30 | Improved comments on the lempar.c parser template. Adjust the YY_SHIFT_USE_DFLT constant in the Lemon-generated parser tables so as to guarantee that it is always out of range of the yy_lookahead[] table. (check-in: 83622f3f50 user: drh tags: trunk) | |
| 11:50 | Fix pcache1TruncateUnsafe() run faster for the case where iLimit is very close to iMaxKey. (check-in: b07a26df06 user: drh tags: trunk) | |
| 01:43 | Performance optimization in the yy_find_shift_action() routine of the Lemon-generated parser. (check-in: ba6663beef user: drh tags: trunk) | |

| 21:08 | Prototype for the remember(V,PTR) extension function. (Closed-Leaf check-in: f0942c362f user: drh tags: rememberFunc) | |
| 21:01 | Fix harmless compiler warning. (check-in: 9a5a4f6e3b user: drh tags: trunk) | |

| 20:54 | Have the TEA package build without SQLITE_OMIT_DEPRECATED. As it uses recently deprecated interfaces sqlite3_profile() and sqlite3_trace(). (check-in: 9557889883 user: dan tags: trunk) | |
| 16:16 | Undo commit [f250166bb]. It is required to handle IO and other errors that occur within a VACUUM of a Zipvfs database. (check-in: ae72513af3 user: dan tags: trunk) | |
| 15:34 | Remove an incorrect ALWAYS() statement and add a test case to show when the condition is sometimes false. (check-in: 0f57effa36 user: drh tags: trunk) | |

| 12:35 | Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. When enabled, the "unknown function" error is suppressed for EXPLAIN and a no-op function named "unknown()" is substituted. This facilitiates using the command-line shell to analyze queries from applications that contain many application-defined functions that are not normally available to the shell.

| 09:09 | Make sure the ORDER BY LIMIT optimization is not applied if the inner-most loop can only have a single iteration and is hence not really a loop. (check-in: 13e3bd3de6 user: drh tags: trunk) | |
