2017-03-11
| ||
| 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: 8b2954dd 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: 7359fcac 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: b5bf2957 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: f8560c60 user: drh tags: trunk) | |
| 16:22 | Add the -DSQLITE_MAX_MEMORY=N compile-time option. The default is no limit. (check-in: eabd4ef4 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: 77dfe2ab 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: 118f5c05 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: b044b152 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: f4fcd46f user: drh tags: trunk) | |
| 18:13 | Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. (check-in: 6c627e50 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: 5dc82a15 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: 50eec5d9 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: aacac906 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: 9b439173 user: drh tags: apple-osx) | |
| 18:06 | Make sure the database connection is open prior to running the ".sha3sum" command. (check-in: 2ea300fb 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: 30f87883 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: fc663799 user: drh tags: trunk) | |
| 15:03 | Improved comments explaining the sha3_query() format. Fix a performance #ifdef error in the sha3 implementation. (check-in: 54ef7abd user: drh tags: trunk) | |
| 13:50 | Add the shathree.c extension for implementing SHA3() and SHA3_QUERY() SQL functions. (check-in: f7ca9193 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: de65f907 user: drh tags: trunk) | |
| 11:44 | Add the --preserve-rowids option to the ".dump" command in the CLI. (check-in: c60aee24 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: 961e79da user: dan tags: trunk) | |
| 14:38 | Performance optimization in the tokenizer/parser loop. (check-in: 2cb71583 user: drh tags: trunk) | |
| 12:18 | Minor comment typo fixes. No changes to code. (check-in: 01cd9fb1 user: drh tags: trunk) | |
| 03:40 | More size and speed improvements in the expression name resolver. (check-in: e0a3d39f user: drh tags: trunk) | |
| 03:25 | Small size reduction and performance increase in the name resolver routine for expressions. (check-in: 1a3554e1 user: drh tags: trunk) | |
|
2017-03-06
| ||
| 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: 73019a8b user: drh tags: trunk) | |
| 20:44 | Fix a typo in a comment. No changes to code. (check-in: ec529bf1 user: drh tags: trunk) | |
| 20:00 | Merge all pending 3.18 enhancements from trunk. (check-in: 1650c3f4 user: drh tags: apple-osx) | |
| 17:33 | Add an initial implementation of the "PRAGMA optimize" command. (check-in: 137aeb2b user: drh tags: trunk) | |
| 11:39 | Merge updates from trunk. (Closed-Leaf check-in: 5f7fc79a user: drh tags: auto-analyze) | |
|
2017-03-02
| ||
| 14:17 | Add an optional bitmask of allowed optimizations on the "PRAGMA optimize" command. The 0x01 bit is Debug Mode. (check-in: a35388ee user: drh tags: auto-analyze) | |
| 13:22 | Merge recent trunk enhancements. (check-in: c60cdb47 user: drh tags: auto-analyze) | |
|
2017-02-23
| ||
| 02:15 | Add two NEVER() operators in the sqlite3BtreeRowCountEst() routine. (check-in: 7a959f6d user: drh tags: auto-analyze) | |
| 00:58 | Do a single OP_Expire at the very end of "PRAGMA optimize", and omit the OP_Expire on ANALYZE commands invoked by the pragma. (check-in: 188300a3 user: drh tags: auto-analyze) | |
|
2017-02-22
| ||
| 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. (check-in: 9fced545 user: drh tags: auto-analyze) | |
| 19:49 | Merge integrity_check and other improvements from trunk. (check-in: fe073905 user: drh tags: auto-analyze) | |
|

| ||
| 13:11 | Merge fixes from trunk. (check-in: ff213f2e user: drh tags: auto-analyze) | |
|
2017-02-18
| ||
| 22:52 | Updated comments. No code changes. (check-in: e842ad39 user: drh tags: auto-analyze) | |
| 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: d386015f user: drh tags: auto-analyze) | |
| 02:42 | Fix errors in the table resize detection. (check-in: 4229caec 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: 882599a4 user: drh tags: auto-analyze) | |
|
2017-02-17
| ||
| 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: bfbdd074 user: drh tags: auto-analyze) | |
| 16:26 | Add the "PRAGMA analyze_as_needed" command. (check-in: e93db237 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: fb2b8ae8 user: drh tags: auto-analyze) | |
