Following month ↑|
2013-12-24
| ||
| 12:09 | Merge the latest trunk changes into the sessions branch. (check-in: cfd110bf5d user: drh tags: sessions) | |
| 12:04 | Add -I. to the main.mk makefile for building sqlite3.o and speedtest1. (check-in: cc72c5aec7 user: drh tags: trunk) | |
|
2013-12-23
| ||
| 19:09 | Move elements of the Vdbe object that are only used during statement preparation out into the Parse object. (check-in: c289a253c0 user: drh tags: trunk) | |
| 15:35 | Make sure the WhereLoop.aLTerm[] array is large enough when processing the skip-scan optimization. Fix for ticket [520070ec7fbaac]. (check-in: ac5852d640 user: drh tags: branch-3.8.2) | |
| 11:33 | Remove a stray tab character. (check-in: 25b8a1c9ba user: drh tags: trunk) | |
|
2013-12-22
| ||
| 22:45 | Remove a condition that is always in the logic that handles reading default values for columns. (check-in: 895af097e7 user: drh tags: trunk) | |
| 20:44 | Make sure the WhereLoop.aLTerm[] array is large enough when processing the skip-scan optimization. Fix for ticket [520070ec7fbaac]. (check-in: 46d040591f user: drh tags: trunk) | |
|
2013-12-21
| ||
| 17:14 | Fix speedtest1.c so that in --explain mode it only outputs non-explain text for DDL statements. (check-in: 2d2b3c4951 user: drh tags: trunk) | |
| 17:07 | Avoid compiler warnings by only enabling sqlite3ErrName() when SQLITE_TEST is defined. (check-in: 862228e505 user: drh tags: trunk) | |
| 16:06 | Fix harmless compiler warnings in FTS4. This involved corrupting Martin Porter's beautifully written and elegant stemmer code, making it a little less beautiful and a little less elegant. Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. (check-in: df05679838 user: drh tags: trunk) | |
| 15:46 | Fix the ".echo on" dot-command of the shell so that it echos comments in addition to SQL statements and dot-commands. Add the --explain option to speedtest1 so that the output can be piped into the command-line shell to show nicely-formated VDBE code for the entire test. (check-in: 96397263f9 user: drh tags: trunk) | |
| 00:04 | Add a case to speedtest1.c that demonstrates the need to factor OP_Column operators out of inner loops. (check-in: 69a17336fd user: drh tags: trunk) | |
|
2013-12-20
| ||
| 18:57 | Fix compiler harmless warnings in tclsqlite.c that appeared with GCC 4.8.x. (check-in: d93ae6833a user: drh tags: trunk) | |
| 18:44 | Code simplification in sqlite3GenerateIndexKey() by making use of a subroutine found over in expr.c. (check-in: 0026d33553 user: drh tags: trunk) | |
| 15:59 | Combine adjacent single-register OP_Copy instructions into a single multi-register OP_Copy, where possible. Fix the Synopsis comment for multi-register OP_Copy instructions to show the correct register ranges. (check-in: 2ae22dc0cb user: drh tags: trunk) | |
| 14:48 | Allow any arbitrary expression as the filename in an ATTACH statement, including functions and subqueries. (check-in: df70a1f303 user: drh tags: trunk) | |
| 13:11 | Simplify the accumulator reset for aggregate query processing so that it uses a single multi-register OP_Null rather than a separate OP_Null for each register. (check-in: 2c7fd9b043 user: drh tags: trunk) | |
|
2013-12-19
| ||
| 17:04 | Do not inject OOM faults into SQLITE_FCNTL_COMMIT_PHASE_TWO file-control invocations. It causes problems for test scripts. (check-in: 8eb28d23e3 user: dan tags: trunk) | |
| 16:26 | Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. (check-in: ca3fdfd419 user: drh tags: trunk) | |
| 14:34 | Remove an unneeded column-cache flush in aggregate SELECT and an unreachable branch in the INSERT logic. (check-in: ffa092e13b user: drh tags: trunk) | |
| 02:56 | Omit an unnecessary OP_Null opcode from UPDATE. (check-in: 72d111336c user: drh tags: trunk) | |
| 02:23 | Omit one or more pointless instructions that occur in between OP_NoConflict and OP_Halt. (check-in: 61e2f3575c user: drh tags: trunk) | |
|
2013-12-18
| ||
| 18:44 | Remove an unnecessary column-cache flush operation. Add code to trace the column cache when compiled with SQLITE_DEBUG and using PRAGMA vdbe_addoptrace=ON. (check-in: 58704ed1f4 user: drh tags: trunk) | |
| 16:27 | Remove an unnecessary column-cache flush. Add another test case to the speedtest1.c program to accentuate the benefit of not flushing the cache at that point. (Closed-Leaf check-in: 97fdfc6b79 user: drh tags: column-cache-debug) | |
| 15:11 | Show changes to the column cache when PRAGMA vdbe_addoptrace=ON is set. (check-in: 4c6a659c43 user: drh tags: column-cache-debug) | |
|
2013-12-17
| ||
| 16:32 | Add evidence marks and additional test cases for the printf() SQL function. (check-in: 93121d3097 user: drh tags: trunk) | |
| 16:10 | Add the printf() SQL function. (check-in: a1bb62f91a user: drh tags: trunk) | |
| 15:58 | Fix the formatting of %c in the printf() SQL function. (Closed-Leaf check-in: 3375571a5e user: drh tags: printf-sql-function) | |
| 15:03 | Add the printf() SQL function. (check-in: 6db7052eee user: drh tags: printf-sql-function) | |
|
2013-12-14
| ||
| 18:24 | Merge in all recent preformance enhancements from trunk. (check-in: 32477642d7 user: drh tags: sessions) | |
| 13:44 | Allow the SQLITE_DETERMINISTIC flag to be ORed into the preferred text encoding of application-defined functions, to mark the function as deterministic. (check-in: 5716fc2341 user: drh tags: trunk) | |
|
2013-12-13
| ||
| 20:45 | Performance optimizations in the pager_write() routine of pager.c. (check-in: bc5febef92 user: drh tags: trunk) | |
| 19:48 | Reduce the number of calls to the subjRequiresPage() routine inside of pager. (check-in: e50ff39a93 user: drh tags: trunk) | |
| 19:35 | Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. (check-in: e00f37e233 user: drh tags: trunk) | |
| 18:50 | Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. (check-in: a845779cd3 user: drh tags: trunk) | |
| 16:42 | Avoid unnecessary calls to sqlite3_free() from within sqlite3VXPrintf(). (check-in: e2a8b280e8 user: drh tags: trunk) | |
| 16:23 | Simplication and optimization of error message handling. (check-in: 9d347f547e user: drh tags: trunk) | |
|
2013-12-11
| ||
| 15:47 | Add the SQLITE_FCNTL_SYNC and SQLITE_FCNTL_COMMIT_PHASETWO file-controls and have the pager call them at appropriate times. This is needed in order to enable ZIPVFS to do multi-file atomic commits. (check-in: 552f94d50f user: drh tags: trunk) | |
| 14:17 | Merge in the latest trunk changes. (Closed-Leaf check-in: 9ff4dfe1e3 user: drh tags: zipvfs-multifile-commit) | |
| 14:00 | Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. (check-in: 5e239ecda0 user: drh tags: trunk) | |
| 12:02 | Remove an unreachable conditional inserted by the previous check-in. (check-in: 3e1d55f0bd user: drh tags: trunk) | |
| 11:03 | Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests. (check-in: fdc3f3fa3d user: dan tags: zipvfs-multifile-commit) | |
| 11:00 | Fix harmless compiler warnings. (check-in: a7e5fcd666 user: drh tags: trunk) | |
| 02:21 | Fix harmless compiler warning. (check-in: 2525296d91 user: mistachkin tags: trunk) | |
| 00:59 | Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. (check-in: 4d0781473a user: drh tags: trunk) | |
|
2013-12-10
| ||
| 21:38 | Avoid unnecessary calls to sqlite3VdbeSerialType() from within sqlite3VdbeSerialPut(). (check-in: 079c04a501 user: drh tags: trunk) | |
| 20:53 | In the OP_MakeRecord opcode, factor out affinity changes into separate loop, for a slight performance advantage. (check-in: 1c6ee9b85f user: drh tags: trunk) | |
| 19:49 | Simplify and improve the performance of the sqlite3VdbeMemGrow() routine. (check-in: 48ecf18774 user: drh tags: trunk) | |
| 17:34 | Use SQLITE_FCNTL_SYNC instead of SQLITE_FCNTL_SYNC_OMITTED. Add documentation in for FCNTL_SYNC and FCNTL_COMMIT_PHASETWO. (check-in: 46231af985 user: dan tags: zipvfs-multifile-commit) | |
| 16:35 | Merge changes from the trunk. (check-in: 3ee736a39d user: dan tags: zipvfs-multifile-commit) | |
| 16:27 | Fix handling of errors returned by the SQLITE_FCNTL_OMIT_SYNCED file-control. (check-in: d9a5f44f4a user: dan tags: zipvfs-multifile-commit) | |
|
2013-12-09
| ||
| 23:17 | Simplifications to the OP_MakeRecord opcode and the sqlite3VdbeSerialPut() helper function. (check-in: 7277a76969 user: drh tags: trunk) | |
| 21:48 | Correct the VFS name as reported by the file control when explicitly using the 'win32-longpath' VFS. (check-in: c43b59dac1 user: mistachkin tags: trunk) | |
| 21:06 | Reduce the number of times that OP_Column calls sqlite3VdbeMemMakeWriteable(). (check-in: 6b51863553 user: drh tags: trunk) | |
| 20:43 | Simplify the sqlite3BtreeKeyFetch() and sqlite3BtreeDataFetch() interfaces to the storage engine. (check-in: bf97598592 user: drh tags: trunk) | |
| 20:42 | Modify the way some internal file-controls are invoked. In order to support multi-file transactions in the zipvfs extension. (check-in: 32fb1784af user: dan tags: zipvfs-multifile-commit) | |
| 19:25 | Minor performance optimizations in pager.c. (check-in: ba9eef5f52 user: drh tags: trunk) | |
| 19:03 | Performance optimizations for sqlite3VXPrintf(). (check-in: 9227ad48e1 user: drh tags: trunk) | |
| 12:24 | Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. (check-in: fbfc075a5a user: drh tags: trunk) | |
| 03:07 | Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). (check-in: 2d6dd7c2eb user: drh tags: trunk) | |
| 02:32 | Use memmove() rather than a home-made copy loop in insertCell() too. (check-in: a3d796b167 user: drh tags: trunk) | |
| 01:58 | Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. (check-in: 78e1706804 user: drh tags: trunk) | |
| 01:04 | Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. (check-in: 81f5ae13b2 user: drh tags: trunk) | |
| 00:47 | Use putVarint32() instead of putVarint() for a quantity that can never exceed 2GiB - 1. (check-in: 6996fb3444 user: drh tags: trunk) | |
|
2013-12-08
| ||
| 23:33 | Another simplification to the OP_MakeRecord opcode, making it slightly faster and very slightly smaller. (check-in: f2f5a3ce9d user: drh tags: trunk) | |
| 22:59 | Avoid unnecessary calls to sqlite3VarintLen() from the OP_MakeRecord opcode. (check-in: 7a234fc3c5 user: drh tags: trunk) | |
| 19:54 | Interchange two conditions in an "if" statment in sqlite3PagerAcquire() for very slight (0.06%) overall performance increase. (check-in: fbcc1a3ebb user: drh tags: trunk) | |
|
2013-12-07
| ||
| 23:35 | Do not allow cursor hints to use expressions containing subqueries. This change fixes the problem seen in the previous check-in. (check-in: bfefc57554 user: drh tags: cursor-hints) | |
| 20:39 | If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs. (check-in: 3a9bec524e user: drh tags: cursor-hints) | |
| 17:01 | Increase the version number to 3.8.3. (check-in: 23d00f2287 user: drh tags: trunk) | |
| 16:56 | At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. (check-in: 369a23e006 user: drh tags: trunk) | |
| 16:45 | Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. (Closed-Leaf check-in: 9c59f5af7a user: drh tags: detect-moved-db) | |
| 12:29 | Actually look at i-node numbers to determine whether or not the database file has moved. (check-in: 2b1884dc14 user: drh tags: detect-moved-db) | |
|
2013-12-06
| ||
| 23:25 | Performance optimization to the moveToRoot() subroutine in btree.c. (check-in: b5842a70f8 user: drh tags: trunk) | |
| 22:45 | Use memcmp() instead of the BINARY collating function where possible, for a performance boost. (check-in: c5a3a1af3c user: drh tags: trunk) | |
| 22:44 | Remove some commented-out code from sqlite3BtreeMovetoUnpacked() to try to make it more readable. (check-in: 2d62d1131f user: drh tags: trunk) | |
| 19:58 | Add the SQLITE_READONLY_DBMOVED error code to the sqlite3ErrName() function. (check-in: 7789f801d7 user: mistachkin tags: detect-moved-db) | |
| 17:23 | Only error out on a database file move when attempting to start a write transaction. Assume read transactions are still safe. And make the error SQLITE_READONLY_DBMOVED instead of SQLITE_IOERR_NODB. (check-in: 28348f2ada user: drh tags: detect-moved-db) | |
| 15:49 | Update to the 3.8.2 release. (check-in: e579661a79 user: drh tags: sessions) | |
| 15:37 | Add code to detect if the database file is moved or deleted out from under SQLite and return an SQLITE_IOERR_NODB. (check-in: 8759a8e4d8 user: drh tags: detect-moved-db) | |
| 14:53 | Version 3.8.2 (check-in: 27392118af user: dan tags: trunk, release, version-3.8.2) | |
|
2013-12-05
| ||
| 17:12 | Fix harmless compiler warnings and improve the MSVC makefile. (check-in: c632567063 user: drh tags: trunk) | |
| 16:41 | Fix two potential (and apparently harmless) shift overflows discovered by the -fcatch-undefined-behavior option of clang. (check-in: e19eead8c9 user: drh tags: trunk) | |
|
2013-12-03
| ||
| 23:33 | Make use of the CC nmake macro even when cross-compiling (with MSVC). (Closed-Leaf check-in: aae7b30ebd user: mistachkin tags: memTests) | |
| 22:33 | Fix harmless compiler warnings. (check-in: a12d214ecc user: mistachkin tags: memTests) | |
| 22:32 | Add memory subsystem related defines to the compile-time options list. (check-in: 52a44146dd user: mistachkin tags: memTests) | |
| 20:51 | Merge in trunk changes. (check-in: a2914d6b17 user: drh tags: sessions) | |
| 19:49 | Remove a branch in STAT4 logic that is no longer reachable after the previous change. (check-in: eca7d3f161 user: drh tags: trunk) | |
| 19:16 | Fix a possible (and probably harmless) uninitialized variable in STAT3/4. (check-in: 33ad4f9147 user: drh tags: trunk) | |
| 18:26 | Fix an alignment problem in the stat3/stat4 code affecting 32-bit platforms. (check-in: 14f9bc7901 user: dan tags: trunk) | |
| 17:09 | Fix a typo in fts3varint.test preventing the valgrind permutation test from running. (check-in: b654a4ec72 user: dan tags: trunk) | |
| 10:35 | Modify test file conflict2.test so that it works with the "inmemory_journal" permutation. (check-in: e4164fd8f7 user: dan tags: trunk) | |
| 10:14 | Remove an unnecessary branch from the UPDATE logic - one that was also unreachable except following an OOM on x64. (check-in: 72f9727714 user: drh tags: trunk) | |
| 09:49 | Add a "database_may_be_corrupt" directive to test file fuzz3.test. Reformat an assert() statement in vdbeaux.c to make its intent clearer. (check-in: 9d8a0e1321 user: dan tags: trunk) | |
| 02:52 | Change some unreachable test conditions to NEVER(). (check-in: 7d99858bec user: drh tags: trunk) | |
| 00:11 | Fix a harmless compiler warning on MacOS. (check-in: 74328de1d7 user: drh tags: trunk) | |
|
2013-12-02
| ||
| 21:58 | Merge all recent 3.8.2 beta changes from trunk. (check-in: 67c34ccfa9 user: drh tags: sessions) | |
| 21:25 | Another #if SQLITE_VERSION_NUMBER macro in speedtest1.c for compatibility with older versions of SQLite. (check-in: bc8eacc7f7 user: drh tags: trunk) | |
| 01:24 | Still more #if SQLITE_VERSION_NUMBER macros in test/speedtest1.c to enable compilation against older versions of SQLite. (check-in: 4b20cf4206 user: drh tags: trunk) | |
|
2013-12-01
| ||
| 18:10 | Add some #if SQLITE_VERSION_NUMBER macros to test/speedtest1.c in order to make it compatible with older versions of SQLite so that it can be used for historical speed comparisons. (check-in: a9e1627ae7 user: drh tags: trunk) | |
| 01:18 | Fix typos in the header comment on the sqlite3Atoi64() routine. (check-in: c85e0c546e user: drh tags: trunk) | |
