| 23:02 | Improvements to the logic for adding the "noskipscan" flag to stat1 entries. (check-in: 421b5b54 user: drh tags: analyze-worst-case) | |
| 21:27 | The ANALYZE command automatically appends "noskipscan" to sqlite_stat1 entries that have large worst-case repeat estimates but small average repeat estimates. (check-in: 6326ba58 user: drh tags: analyze-worst-case) | |
| 18:30 | Modify the ANALYZE command to store worst-case statistics in sqlite_stat1, rather thn average case. (check-in: 5a0143c9 user: drh tags: analyze-worst-case) | |
| 15:53 | Reduce the amount of heap required to store many schemas by storing each column datatype appended to the column name, rather than as a separate allocation. (Closed-Leaf check-in: 842b2116 user: drh tags: schema-storage) | |
| 13:44 | Very minor improvement to the performance and reduction in size to the parser by capturing the name and datatype of table columns in a single grammar rule reduction. (check-in: 4b55c520 user: drh tags: trunk) | |
| 13:37 | Further simplifications to the grammar. (Closed-Leaf check-in: 519fd03b user: drh tags: schema-storage) | |
|
2016-02-27
| ||
| 23:25 | Update the parser so that it pulls out the column name and type all in one go, rather than using separate reductions. (check-in: ad3ffe2e user: drh tags: schema-storage) | |
| 21:16 | Eliminate the need for the Column.zDflt (using Column.pDflt instead) to reduce the amount of memory needed to hold the schema. (check-in: d8c94a46 user: drh tags: trunk) | |
| 19:19 | Tighter description of I/O stats in the shell. Show I/O stats on speedtest1.c. (check-in: f681d800 user: drh tags: trunk) | |
| 19:03 | More compact implementation of PRAGMA onconflict, and some test cases. (Leaf check-in: 3e5d38f5 user: drh tags: pragma-onconflict) | |
| 17:16 | Experimental "PRAGMA onconflict=FAIL" statement to change the default ON CONFLICT algorithm to something other than ABORT. (check-in: 3a0c347c user: drh tags: pragma-onconflict) | |
| 17:12 | Enhance the ".stats" command in sqlite3.exe to show one-time stats information if invoked with one argument. Also show /proc/PID/io information if run on Linux. (check-in: 3c36948f user: drh tags: trunk) | |
| 14:04 | Fix a requirement mark to conform to a typo fix in the documentation. (check-in: d1392c62 user: drh tags: trunk) | |
| 14:00 | Enhance documentation of sqlite3_snapshot_open() to explain that the database connection must have participated in at least one read operation prior to the beginning of the transaction for which the snapshot is to be opened. Add test cases for this fact. (check-in: 33dd671c user: drh tags: trunk) | |
| 00:07 | Make sure the Replace.cs file is included in the autoconf tarball. (check-in: b850df48 user: drh tags: trunk) | |
|
2016-02-26
| ||
| 21:20 | Fix a potential buffer overflow in the ICU upper() function. (check-in: b8dc1b9f user: drh tags: trunk) | |
| 16:14 | Merge all recent enhancements from trunk, and in particular the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER change. (check-in: 4fb4aee8 user: drh tags: apple-osx) | |
| 15:38 | Provide the new SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER option to sqlite3_db_config() that can be used to activate the two-argument version of fts3_tokenizer() for a specific database connection at run-time. (check-in: 374b5108 user: drh tags: trunk) | |
| 13:22 | Fix a typo in a comment (though an important comment in that it is used to generate documentation). (check-in: ff3d7f84 user: drh tags: trunk) | |
| 04:15 | • Edit [beda0b8c76c2c732|beda0b8c]: Edit check-in comment. (artifact: 4e9daad8 user: drh) | |
| 04:13 | Ephemeral tables used to hold manifested views may not be unordered since they might be subject to an ordered comparison if they are part of a join. (check-in: 3ef6a315 user: drh tags: trunk) | |
| 04:04 | Remove a debugging "exit" command mistakenly left in the "where.test" module. (check-in: beda0b8c user: drh tags: trunk) | |
|
2016-02-25
| ||
| 23:21 | Fix an incorrect cost computation for sorting (introduced just a few check-ins ago). Should be NlogN, not NloglogN. (check-in: 2459d323 user: drh tags: trunk) | |
| 21:27 | Change the srcck1.c utility program to use only unsigned characters. (check-in: d64d005e user: drh tags: trunk) | |
| 21:19 | Change the "PRAGMA stats" command to report size values in LogEst units. The eliminates the need for sqlite3LogEstToInt() unless non-standard compile-time options are used, so leave it out except in those cases. (check-in: 832c237f user: drh tags: trunk) | |
| 19:54 | • Edit [82470d1c3a41221c|82470d1c]: Mark "Closed". (artifact: 2019414f user: drh) | |
| 18:54 | Merge all the latest changes from trunk. (check-in: b8659004 user: drh tags: sessions) | |
| 18:40 | Query planner improvements: Take the LIMIT into account when estimated the cost of an ORDER BY. Avoid automatic indexes on query loops that are expected to run less than twice. See [9e2b2681] for a later enhancement. (check-in: bf46179d user: drh tags: trunk) | |
| 18:22 | Improvement on the previous check-in: disallow automatic indexes for any loop that is expected to run less than twice. (Closed-Leaf check-in: aab53a21 user: drh tags: planner-improvements) | |
| 18:03 | Do not use an automatic index on an outer loop that only runs once. (check-in: 5957e793 user: drh tags: planner-improvements) | |
| 16:04 | Take the LIMIT clause into account when estimating the cost of sorting. (check-in: d491745c user: drh tags: planner-improvements) | |
| 13:33 | In the command-line shell: When the ".import" command is creating a new table using column names from the first row of CSV input, make sure double-quotes in the name are properly escaped. (check-in: 2e67a1c8 user: drh tags: trunk) | |
|

| 17:18 | When an index completely covers a table, it can be used as a covering index even if columns past the 63rd column are indexed and accessed. (check-in: 3e9ed1ae user: drh tags: trunk) | |
| 15:49 | • Edit [71d488b599cbde81|71d488b5]: Edit check-in comment. (artifact: b41e3f2c user: drh) | |
| 15:43 | Identify indexes that completely cover their table. (Closed-Leaf check-in: 71d488b5 user: drh tags: covering-index) | |
| 13:35 | LSM1: Fix the integer key encoding so that negative keys are in numeric order. (check-in: f92dc418 user: drh tags: lsm-vtab) | |
|
2016-02-23
| ||
| 16:28 | Add the SQLITE_BITMASK_TYPE compile-time option. (check-in: 0064a8c7 user: drh tags: trunk) | |
| 01:41 | Merge trunk enhancements. (check-in: fac4f4ec user: drh tags: lsm-vtab) | |
| 01:37 | Add support for (variable length) integer keys in LSM1. (check-in: 32f3daec user: drh tags: lsm-vtab) | |

| ||
| 23:44 | Remove code not needed now that synchronous=OFF database files no longer trigger the use of a master journal. (check-in: aa9f4c62 user: drh tags: trunk) | |
| 23:14 | Avoid an unnecessary seek operation some corner-case skip-scan operations. (check-in: 2a6003a9 user: drh tags: trunk) | |
| 21:19 | Clearer presentation of the logic. No functional changes. (Closed-Leaf check-in: a3dcf6db user: drh tags: skip-scan-improvement) | |
| 20:52 | Avoid an unnecessary seek operation on some corner-case skip-scans. (check-in: 38e837e6 user: drh tags: skip-scan-improvement) | |
| 16:32 | Merge the master-journal optimization and other recent changes from trunk. (check-in: 18c3ab47 user: drh tags: apple-osx) | |
| 16:04 | Always use the sqlite3VdbeDeleteAuxdata() routine for clearing auxdata on function parameter, rather than having a separate deleteAuxdataFromFrame() for doing the job for trigger frames. (check-in: 64386fa3 user: drh tags: trunk) | |
| 14:57 | Avoid creating a master journal unless two or more databases in the transaction can actually benefit from that master journal. (check-in: 3ed18906 user: drh tags: trunk) | |
| 13:23 | Change magic numbers associated with synchronous settings to named constants. (check-in: 9230ba6c user: drh tags: trunk) | |

| ||
| 14:53 | Merge the tokenizer buffer overrun bug-fix from trunk. (check-in: 82e7e31b user: drh tags: apple-osx) | |
| 14:49 | Avoid a potential buffer overrun if an SQL statement being parsed ends with an illegal "!" token. (This problem was detected by fuzzcheck running under valgrind. The problem was introduced by check-in [9570b6b43df3], two days ago and has not appeared in a release.) (check-in: 2a8d97e7 user: drh tags: trunk) | |
| 14:03 | Improved handling of the -v option on the fuzzcheck test program. (check-in: c8cd7804 user: drh tags: trunk) | |

|
2016-02-17
| ||
| 20:47 | When VDBE opcodes fail, they cause an immediate exit from the loop, rather than depending on the rc==SQLITE_OK test at the top of the loop. This is faster and smaller. (check-in: 24c7151c user: drh tags: trunk) | |
| 18:44 | Fix up all VDBE opcodes so that they cause an immediate exit on any kind of error, and thereby eliminate the need to test "rc" at the top of the loop. Resulting code is a little smaller and faster. (Closed-Leaf check-in: a444633a user: drh tags: vdbe-performance) | |
| 15:01 | Bump the version number to 3.12.0. (check-in: c17d7276 user: drh tags: trunk) | |
| 13:24 | Enhance Lemon to generate more compact and efficient code for yy_reduce(). Update the main SQL grammar to take advantage of the new capabilities. (check-in: 53fd040c user: drh tags: trunk) | |
| 12:34 | More agressive use of /*A-overwrites-X*/ in the parser. Fix an off-by-one error in parser stack overflow detection. (Closed-Leaf check-in: 417e7777 user: drh tags: parser-performance) | |
| 11:13 | Documentation typo on sqlite3_wal_hook(). No changes to code. (check-in: fc2043eb user: drh tags: trunk) | |
| 04:33 | Enhance Lemon so that if reduce code contains a comment of the form "/*A-overwrites-X*/" then a LHS label A is allowed to overwrite the RHS label X. (check-in: 5cfe9545 user: drh tags: parser-performance) | |
| 01:46 | Further improvements to the Lemon-generated code for yy_reduce(). (check-in: ef95a7d6 user: drh tags: parser-performance) | |
| 01:18 | In Lemon, add the ability for the left-most RHS label to be the same as the LHS label, causing the LHS values to be written directly into the stack. (check-in: 4bb94c7c user: drh tags: parser-performance) | |
|
2016-02-16
| ||
| 21:19 | Experimental changes to Lemon for improved parser performance. (check-in: a65d583c user: drh tags: parser-performance) | |
| 13:04 | Minor simplification to the tokenizer. Slightly smaller and faster. (check-in: 9570b6b4 user: drh tags: trunk) | |
| 01:01 | Improve the Lemon parser template (lempar.c) so that it avoids unnecessary work when the grammer defines YYNOERRORRECOVERY (as SQLite does). Slightly smaller and faster code results. (check-in: 9235b0cf user: drh tags: trunk) | |
|
2016-02-15
| ||
| 23:46 | Fix a harmless compiler warning in FTS5. (check-in: e52c9075 user: drh tags: trunk) | |
| 21:31 | On windows systems when rand_s() is available, use it to obtain additional seed material in winRandomness(). (check-in: 139081be user: drh tags: trunk) | |
| 20:41 | Improved entropy gathering for the implementation of winRandomness(). (check-in: fea3705e user: drh tags: trunk) | |
| 19:38 | Add working -q and --help options to testfixture. (check-in: 404494e5 user: drh tags: trunk) | |
| 18:58 | In the tool/warning.sh script, disable Android-specific compiler warning tests when not running on Linux. (check-in: 153f01a8 user: drh tags: trunk) | |
| 18:47 | Fix harmless compiler warnings previously seen in 64-bit MSVC builds. (check-in: 70262463 user: drh tags: trunk) | |
| 18:15 | Add the SQLITE_NOMEM_BKPT macro to enhance the ability to debug OOM errors. Only effective with compiling with SQLITE_DEBUG. (check-in: 9b345476 user: drh tags: trunk) | |
| 18:02 | • Edit [a863729ccb75a563|a863729c]: Mark "Closed". (artifact: 29e3a3a0 user: drh) | |
| 18:02 | Minor code simplifications. (check-in: c3b38efd user: drh tags: trunk) | |

| 00:34 | Improvements to the application-defined function mechanism so that it is more compact and runs faster, especially when the application defines thousands of new SQL functions. (Closed-Leaf check-in: 3201fbcc user: drh tags: many-app-functions) | |
|
2016-02-13
| ||
| 18:54 | Provide Sqlite3_SafeInit() and Sqlite3_SafeUnload() entry points on the TCL interface, but have the always return TCL_ERROR, because the non-standard TCL builds on Macs require this. (check-in: 37ec3015 user: drh tags: trunk) | |

2016-02-12
| ||
| 17:30 | Fix a documentation typo. No changes to code. (check-in: d9c98587 user: drh tags: trunk) | |
| 17:27 | Enhance mptester so that it takes great care to delete its test database prior to start-up, including checking the return code from unlink() and retrying after a delay if unlink() fails. Hopefully this will clear intermittant startup problems on Windows. (check-in: 6ea84ec1 user: drh tags: trunk) | |
| 00:13 | Remove an unused parameter from whereSortingCost(). (check-in: b5d77199 user: drh tags: trunk) | |
|
2016-02-11

| 22:41 | Automatically disable FTS3 and FTS4 when building with SQLITE_OMIT_VIRTUALTABLE. (check-in: 0beb32d2 user: drh tags: trunk) | |
| 21:55 | Remove the unexplained extra 3.0 cost factor for the B-tree sorting that is done to implement DISTINCT in the absence of an index to help. (check-in: 52571991 user: drh tags: trunk) | |
| 21:53 | Remove the unused fts5BlobCompare() routine. (check-in: defc762d user: drh tags: trunk) | |
| 15:37 | Add JSON1 and FTS5 to the set of extensions subject to close compiler warning analysis. Fix some warnings in each. More (harmless) warnings still exist in FTS5. (check-in: cfe2eb88 user: drh tags: trunk) | |

|
2016-02-10
| ||
| 19:10 | Add testcase() macros to the CHECK constraint avoidance logic. Avoid creating an unused VDBE label during CHECK constraint code generation. (check-in: 970881be user: drh tags: trunk) | |
| 18:24 | Fix to previous check-in: Make sure CHECK constraints involving the ROWID are not ignored when the ROWID changes. (check-in: 7782cb1d user: drh tags: trunk) | |
| 16:52 | Omit unnecessary CHECK constraints in UPDATE statements, when none of the columns referenced in the CHECK constraint are modified. (check-in: 02fbdbc7 user: drh tags: trunk) | |
| 16:03 | Omit NOT NULL checks on unchanging columns in an UPDATE. (check-in: 6a3aaedf user: drh tags: trunk) | |
| 13:36 | When generating the snapshot-tarball, truncate the date/time in the name to 12 significant digits (YYYYMMDDhhmm) omitting the seconds and fractional seconds. (check-in: 604f7775 user: drh tags: trunk) | |
| 13:17 | Updates to the autoconf tarball README.txt file. (check-in: a3e911e3 user: drh tags: trunk) | |
|
2016-02-09
| ||
| 22:54 | Update the snapshot tarball name to use the date (ISO8601 format) instead of the SHA1 hash in its name. (check-in: 070ec66f user: drh tags: trunk) | |
| 22:39 | Add the new "snapshot-tarball" target to the unix makefiles, for building a tarball similar to "amalgamation-tarball" but named by the SHA1 hash of the current check-out rather than by the version number. (check-in: 4f360b2a user: drh tags: trunk) | |
| 20:37 | Fix the makefiles in the autoconf-tarball so that they build the command-line shell with SQLITE_ENABLE_EXPLAIN_COMMENTS. (check-in: 1135ad01 user: drh tags: trunk) | |
| 20:11 | Enhance the command-line shell to be in auto-explain mode by default. It is no longer necessary to use the ".explain" command to put the shell into a mode where the EXPLAIN output is formatted nicely. That now happens automatically. (check-in: 751915cb user: drh tags: trunk) | |
| 20:04 | Improved auto-detection of EXPLAIN output in the shell. (Closed-Leaf check-in: 6c6d7a6e user: drh tags: auto-explain) | |
| 18:39 | Add auto-explain mode to the command-line shell. Default on. Auto-explain tries to automatically detect EXPLAIN queries and format them appropriately. (check-in: 1d62aa6b user: drh tags: auto-explain) | |
| 17:12 | Fix the top-level makefiles to always include SQLITE_ENABLE_EXPLAIN_COMMENTS when building the shell. Still need to fix main.mk and the amalgamation tarball. (check-in: 99228239 user: drh tags: trunk) | |
| 16:09 | Code simplification: ALTER TABLE ADD COLUMN always upgrades the file_format to 4 if is not there already. No need to upgrade to only 2 or 3 since format 4 has now been supported for over 10 years. (check-in: e1d8ec85 user: drh tags: trunk) | |
| 15:50 | Merge recent fixes and enhancements from trunk. (check-in: f0734017 user: drh tags: apple-osx) | |

| 14:12 | • Fixed ticket [d06a25c8]: Incorrect result from a UNION with an ORDER BY plus 6 other changes (artifact: 1ef35260 user: drh) | |
| 02:12 | Make sure every co-routines has its own set of temporary registers and does not share temporaries, since a co-routine might expect the content of a temporary register to be preserved across an OP_Yield. Proposed fix for ticket [d06a25c84454a]. (check-in: ca72be86 user: drh tags: trunk) | |

| 03:23 | Faster keywordCode() implementation by taking advantage of the fact that the input is always pure ASCII alphabetic and underscore and that the keyword table is always upper-case. (check-in: ff406b97 user: drh tags: tokenizer-char-class) | |
| 02:30 | Demonstrate a much faster sqlite3GetToken() routine by using a lookup table to map initial token characters into a character class. This check-in does not work for EBCDIC. More optimization needed. (check-in: 9115baa1 user: drh tags: tokenizer-char-class) | |

| 14:11 | Improvements to the way out-of-memory conditions are handled, resulting in an almost 1% performance gain in the commmon case where OOM errors do not occur. (check-in: b082538d user: drh tags: trunk) | |
| 13:38 | Add the slightly faster sqlite3DbMallocRawNN(db,n) routine for the majority cases where db is guaranteed to be not NULL. (Closed-Leaf check-in: 0a802e96 user: drh tags: oom-handling) | |
| 04:50 | OOM failures on sqlite3_errmsg16() in an app-defined function are no longer benign. (check-in: 9efb223f user: drh tags: oom-handling) | |
| 02:50 | Minor simplification of schema error reporting. (check-in: a8846aee user: drh tags: oom-handling) | |
| 02:42 | Further performance improvements that fall out of the mallocFailed changes. (check-in: d94416dd user: drh tags: oom-handling) | |
| 01:55 | Improvements to the way that OOM errors are processed. (check-in: c3ef0347 user: drh tags: oom-handling) | |

| 19:50 | Temporarily back out the 0.5% performance improvement from check-in [632071bac5ff32]. Need a more elaborate solution that works with reentrant virtual tables and SQL functions. (check-in: 42736fb0 user: drh tags: trunk) | |
| 11:48 | Remove unnecessary sets of db->mallocFailed. (check-in: b787165b user: drh tags: trunk) | |
| 11:15 | Use sqlite3_malloc64() instead of sqlite3_malloc() in the spellfix extension. (check-in: 634d008c user: drh tags: trunk) | |
| 10:28 | • Fixed ticket [ad2559db]: JSON does not properly escape control characters plus 5 other changes (artifact: 0134f388 user: drh) | |
| 10:28 | Escape control characters in JSON. Fix for ticket [ad2559db380abf8]. (check-in: 4f1b5229 user: drh tags: trunk) | |
| 10:14 | • New ticket [ad2559db] JSON does not properly escape control characters. (artifact: 9f98f001 user: drh) | |
| 09:48 | Refinements to synchronous logic: (1) Use PAGER_SYNCHRONOUS_FULL rather than the corresponding magic number. (2) Honor SQLITE_NO_SYNC on xDelete calls with sync (3) Count xDelete syncs during testing (4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal unlink are off by default. (check-in: e3157cb5 user: drh tags: trunk) | |
| 02:34 | Add and use the sqlite3VdbeZeroRegister() interface for coding the common operation of writing zero into a register. (Leaf check-in: 1c8d3001 user: drh tags: zero-register) | |

| 22:14 | In the VDBE loop, only check for OOM errors at jumps rather than after every opcode, for about a 0.5% performance increase. (check-in: 632071ba user: drh tags: trunk) | |
| 19:52 | Fix markup errors in comments used to generate the documentation - specifically in the documentation on the OP_Seek opcode. (check-in: ef252bc4 user: drh tags: trunk) | |
| 19:20 | Add "PRAGMA synchronous=EXTRA" which syncs the directory containing the rollback journal when the rollback journal is deleted in order to commit a transaction in DELETE mode. (check-in: af924018 user: drh tags: trunk) | |
| 01:55 | Enhance the internal sqlite3VdbeAddOpList() interface to automatically update jump destinations. Use this feature to simplify the AUTOINCREMENT code generator. (check-in: ae8b9d2e user: drh tags: trunk) | |

| 02:04 | Enhance the comment on the sqlite3_index_constraint object to bring attention to the fact than iColumn field can be negative for a rowid. (check-in: d8b7b199 user: drh tags: trunk) | |
| 00:59 | Add the SQLITE_DBCONFIG_REQUIRE_WRITE_TXN connection setting, which if enabled requires all write operations to be enclosed within BEGIN ... COMMIT. (Leaf check-in: 7453790c user: drh tags: require-write-txn) | |

| 21:48 | Change the OP_SetCookie instruction to write the literal P3 value, not the value in register P3. (check-in: 6d7d4703 user: drh tags: trunk) | |
| 17:20 | Number VDBE opcodes starting with 0 instead of 1, as this obviates the lower-bound test on "switch(opcode){...}", making the code smaller and faster. (check-in: 4c9222f7 user: drh tags: trunk) | |
| 13:21 | Minor simplification to the OP_AutoCommit opcode. Fix some code comments related to transaction control. (check-in: a9b6a067 user: drh tags: trunk) | |
| 00:21 | Fix an assert() that might fail on a corrupt database. (check-in: 22eaced7 user: drh tags: trunk) | |
