| 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) | |

2017-03-12
| ||
| 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) | |

|
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
| ||

| 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) | |

| 11:44 | Add the --preserve-rowids option to the ".dump" command in the CLI. (check-in: c60aee2471 user: drh tags: trunk) | |
|
2017-03-07
| ||
| 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].

| 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) | |
| 20:43 | Fix another corner-case for the 'start of ...' modifier in the date/time functions. Related to ticket [6097cb92745327a1]. (check-in: 8831f4393d user: drh tags: trunk) | |
