| 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) | |

| 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) | |

| 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.

|
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

| 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) | |

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

| 16:51 | 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. (check-in: 915a9a2878 user: dan tags: trunk) | |
|
2017-03-02
| ||
| 23:40 | Fix a bug in the 'start of ...' date/time modifiers when they follow a julian day number. Fix for ticket [6097cb92745327a1]. (check-in: 081dbcfb6d user: drh tags: trunk) | |
| 16:56 | Fix another RBU case similar to the previous. This one for systems where the sector-size is larger than the page-size. (check-in: 4012bb3aa9 user: dan tags: trunk) | |
| 14:51 | 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. (check-in: edee6a80e1 user: dan tags: trunk) | |
| 14:17 | Add an optional bitmask of allowed optimizations on the "PRAGMA optimize" command. The 0x01 bit is Debug Mode. (check-in: a35388eef4 user: drh tags: auto-analyze) | |

| 20:24 | Change the name of the analyze_as_needed pragma to "optimize". Enhance the comment (which will become documentation, assuming these changes land on trunk) to explain that the optimize pragma is likely to be enhanced in various ways in future releases and that applications should not depend upon the current behavior.

| 23:32 | Correct a harmless typo in the previous check-in. (check-in: 1589db012e user: mistachkin tags: trunk) | |
| 19:13 | Avoid unsigned integer overflows for SQLITE_WIN32_HEAP_INIT_SIZE when the Win32 heap subsystem is used with very large values of SQLITE_DEFAULT_CACHE_SIZE and/or SQLITE_DEFAULT_PAGE_SIZE. (check-in: 96b6a98e5e user: mistachkin tags: trunk) | |
| 14:30 | Small grammar simplification. (check-in: 0d8a868acd user: drh tags: trunk) | |

| 22:52 | Updated comments. No code changes. (check-in: e842ad391e user: drh tags: auto-analyze) | |
| 20:05 | Add an optimization to OP_Column to speed up sequential OP_Column instructions that read earlier fields from the same cursor. Attempt to reorder OP_Column opcodes so as to take advantage of this. (Leaf check-in: c1adf95958 user: dan tags: sort-column-opcodes) | |
| 15:58 | Add the OP_SqlExec opcode and use it to implement "PRAGMA analyze_as_needed", invoking ANALYZE subcommands as necessary. This simplifies the implementation. (check-in: d386015f5e user: drh tags: auto-analyze) | |
| 13:47 | Add the SQLITE_BUG_COMPATIBLE_20160819 compile-time option to omit the error message when an unrecognized argument is provided to the VACUUM command. (check-in: 491814272d user: drh tags: trunk) | |
| 02:42 | Fix errors in the table resize detection. (check-in: 4229caec0b user: drh tags: auto-analyze) | |
| 02:19 | In the analyze_as_needed pragma, avoid running unnecessary OP_LoadAnalysis and OP_Expire opcodes. Make the analyze_as_needed pragma responsive to the schema name. (check-in: 882599a4a7 user: drh tags: auto-analyze) | |

| 23:52 | Fix the #endif location for an #ifndef SQLITE_UNTESTABLE macro in the command-line shell. (check-in: 8cc9d74c17 user: drh tags: trunk) | |
| 19:24 | The analyze_as_needed pragma now responds to table size growth and will automatically rerun the analysis after each 10x size increase. (check-in: bfbdd07409 user: drh tags: auto-analyze) | |
| 16:26 | Add the "PRAGMA analyze_as_needed" command. (check-in: e93db23731 user: drh tags: auto-analyze) | |
| 15:26 | Set the TF_StatsUsed flag on tables when the query planner outcome is affected by the sqlite_stat1 data. Also, change the column names of the "PRAGMA stats" command so that they are not keywords. (check-in: fb2b8ae831 user: drh tags: auto-analyze) | |
| 13:38 | Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats". These are all preliminary steps toward a "PRAGMA analyze_ifneeded;" feature. (check-in: 85026c8ee1 user: drh tags: auto-analyze) | |
| 02:07 | Merge fixes from trunk. (Leaf check-in: 662e8ccf7e user: drh tags: increased-sorting-cost) | |
| 02:04 | Fix a test case that was made to fail by the LIKE optimization enhancement in check-in [158290c0ab] but which went unnoticed because test builds were running with ICU enabled and ICU disables the LIKE optimization. (check-in: 218b2bbb0d user: drh tags: trunk) | |
| 01:43 | Enable the ".wheretrace" and ".selecttrace" extensions in the command-line shell when compiled on Windows using DEBUG=3 or higher. Fix a harmless warning in the shell that comes up when compiled this way. (check-in: 8a03be1dc4 user: drh tags: trunk) | |

| 21:29 | Increase the estimated cost of sorting when sorting wide results sets, to account for the extra storage space and I/O required for the external sort. (check-in: aa0703e5ce user: drh tags: increased-sorting-cost) | |
| 20:52 | Change the name of WhereInfo.pDistinctSet to pResultSet, since it is now used for more than just DISTINCT processing. (check-in: 9fc5cd505f user: drh tags: trunk) | |
| 17:18 | Change two MallocZero() calls into MallocRaw() to avoid unnecessary memset(). (check-in: ff5e733cbf user: drh tags: trunk) | |
| 16:26 | Fix a comment on a field of the ExprList object. No changes to code. (check-in: bb8e264227 user: drh tags: trunk) | |
| 15:57 | Increase Table.tabFlags from 8 to 32 bits. (check-in: 7e14044c65 user: drh tags: trunk) | |
| 15:06 | Remove two redundant initializations from the virtual table logic. (check-in: 6bd82b95a6 user: drh tags: trunk) | |
| 14:48 | Always use the IsVirtual() macro to determine if a Table object is a virtual table. Slightly smaller and faster code. (check-in: 6affb1c89d user: drh tags: trunk) | |
