2013-08-07
| ||
| 14:18 | Add a guard #ifndef to test_intarray.h to prevent harm if it is #included more than once. Add a comment on the closing #endif of the guards on sqlite3.h and test_multiplex.h. (check-in: 0ad83ceb79 user: drh tags: trunk) | |
| 01:18 | Fix typos and add clarification to comments in where.c. No code changes. (check-in: f8d8790ede user: drh tags: trunk) | |

| 20:15 | Fixes for builds without SQLITE_ENABLE_STAT4. (check-in: 84999e27cc user: dan tags: sqlite_stat4) | |
| 20:01 | When possible, use the multi-column samples in sqlite_stat4 to estimate the number of index rows scanned by a query plan. (check-in: 2973f5ca73 user: dan tags: sqlite_stat4) | |
| 19:18 | Fix a test case related to partial indices so that it works even if STAT3 is disabled. (check-in: 153c645025 user: drh tags: trunk) | |
| 18:35 | Adjust #ifdefs in test_autoext.c so that it compiles with SQLITE_OMIT_LOAD_EXTENSION. Fix compiler warnings in two other test modules. No changes to the core. (check-in: 89930ea3c3 user: drh tags: trunk) | |
| 18:21 | Update the configure script to use the latest version number (3.8.0). (check-in: 52e8ec5e24 user: drh tags: trunk) | |
| 17:24 | Add a testcase() macro to verify OOM coverage. (check-in: d43dcbc488 user: drh tags: trunk) | |
| 16:56 | Remove unreachable branches in expr.c, replacing them with assert() and testcase() statements. (check-in: 9103c27ceb user: drh tags: trunk) | |
| 14:52 | Merge in the latest changes from trunk. (check-in: 69d5bed017 user: drh tags: sessions) | |
| 14:36 | For the ".import" command of the command-line shell, start a transaction if there is not one active already. (check-in: 5dcc2d91bd user: drh tags: trunk) | |
| 14:01 | Clean up the input reader in the command-line shell for improved legibility and performance. (check-in: 2b1743d601 user: drh tags: trunk) | |
| 07:45 | More than double the speed of the resolveP2Values() routine in vdbeaux.c by moving from an extended if-else on every opcode to a switch. Opcodes are reordered in mkopcodesh.awk to put the switched opcodes close together, for additional performance and to reduce code footprint. (check-in: 924f7e4d7a user: drh tags: trunk) | |

2013-08-05
| ||
| 22:05 | Performance optimization: Avoid calling convertCompoundSelecctToSubquery() on queries that do not use the UNION, EXCEPT, or INTERSECT operators. (check-in: c589b2fed7 user: drh tags: trunk) | |
| 21:54 | For the vtshim module, always zero out the xChildDestroy function pointer after calling it. (check-in: 240f7252c6 user: mistachkin tags: trunk) | |
| 19:11 | Factor all KeyInfo object allocations into a single function: sqlite3KeyInfoAlloc(). Always allocate enough space so that sqlite3VdbeRecordCompare() can avoid checking boundaries and hence run faster. (check-in: 7301bedd94 user: drh tags: trunk) | |
| 19:04 | Modify the vdbe code generated by ANALYZE to use fewer memory cells and cursor slots. (check-in: 4a51cf289f user: dan tags: sqlite_stat4) | |
| 18:00 | Use N separate cursors when scanning an index with N columns to collect sqlite_stat4 data. This fixes a problem with collecting incorrect nEq values from multi-column indexes. (check-in: 3a71afe674 user: dan tags: sqlite_stat4) | |
| 15:32 | Improve performance of sqlite3VdbeRecordCompare() by using an approximation that might give false negatives and only running the more expensive exact subexpression if the approximation fails. (check-in: 28979dcd16 user: drh tags: trunk) | |
| 12:31 | Add a missing '#include "tcl.h"' to test_rtree.c. (check-in: 4b8b426f10 user: drh tags: trunk) | |
| 05:34 | Fix a couple of problems in code related to sqlite_stat4. (check-in: badd24d987 user: dan tags: sqlite_stat4) | |
|
2013-08-03
| ||
| 20:24 | Begin adding experimental sqlite_stat4 table. This commit is buggy. (check-in: 2beea303a1 user: dan tags: sqlite_stat4) | |
|
2013-08-02
| ||
| 23:40 | Updates to requirements marks. No code changes. (check-in: 213020769f user: drh tags: trunk) | |
| 20:44 | Merge in the latest trunk changes, including partial indexes, the MAX_PATH fix in os_win.c, and the sqlite3_cancel_auto_extension() API. (check-in: 7e1acb3907 user: drh tags: sessions) | |
| 20:11 | Add NEVER() and ALWAYS() macros on some unreachable yet prudent branches. (check-in: c5c0a8ab6c user: drh tags: trunk) | |
| 16:41 | Add support for partial indices. (check-in: 478113f18b user: drh tags: trunk) | |
| 14:18 | Silently ignore database name qualifiers in CHECK constraints and in partial index WHERE clauses. (Closed-Leaf check-in: 2e8c845eb5 user: drh tags: partial-indices) | |
| 13:31 | Fix typos in documentation for SQLITE_DBSTATUS_DEFERRED_FKS . No changes to code. (check-in: f3efbfcd51 user: drh tags: trunk) | |
|
2013-08-01
| ||
| 22:27 | Fix the CREATE INDEX statement so that trying to create a TEMP index on a non-TEMP table throws an error rather than segfaulting. (check-in: e3c8935f87 user: drh tags: trunk) | |
| 22:26 | Fix an incorrect expected result in a test case in corruptG.test. (check-in: 6913831ad2 user: drh tags: trunk) | |
| 20:26 | Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a serial_type specifies a field that starts in bounds but is much too large for the allocated buffer. Mostly harmless. The overread is unlikely to go more than one or two bytes past the end of the buffer. (check-in: e436b2f4e5 user: drh tags: trunk) | |
| 19:17 | Make sure signed integer overflow does not cause a segfault while attempting to read a corrupt database where the header size varint on a record is larger than the maximum 32-bit signed integer. (check-in: c3baca99f4 user: drh tags: trunk) | |
| 17:43 | Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718b5 user: dan tags: trunk) | |
| 17:21 | An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b776d user: drh tags: trunk) | |
| 16:52 | Avoid using left-most column STAT3 samples if the left-most column has an equality constrain and there are inequality constraints on the second column. (check-in: 31b4e63b3c user: drh tags: trunk) | |
| 16:02 | Fix bug in the logic that determines the end of a CREATE INDEX statement. Added a VACUUM test case that exposed the bug. (check-in: 2e3df0bc90 user: drh tags: partial-indices) | |
| 15:09 | More test cases and corresponding bug fixes. (check-in: 0c8cfdfae2 user: drh tags: partial-indices) | |
| 13:04 | Fill out an initial implementation of the sqlite3ExprImpliesExpr() function. (check-in: 8e07aa2ad5 user: drh tags: partial-indices) | |
| 12:21 | Refactor internal function name sqlite3VdbeGetValue() to sqlite3VdbeGetBoundValue(). (check-in: 81834c3023 user: drh tags: partial-indices) | |
| 04:39 | Fix the ANALYZE command to work with partial indices. (check-in: 60353124f4 user: drh tags: partial-indices) | |
| 03:36 | Test cases and bug fixes for the partial index logic. (check-in: 6b73ae7c12 user: drh tags: partial-indices) | |
| 01:14 | Add the logic to keep partial indices up to date through DML statements and when new partial indices are created. This new logic is untested except to verify that it does not interfere with full indices. (check-in: fb9044d15a user: drh tags: partial-indices) | |
|
2013-07-31
| ||
| 23:28 | Limit the number of memset() calls used when determining a temporary file name on Windows. Also, fix a harmless compiler warning. (check-in: 136fc2931b user: mistachkin tags: trunk) | |
| 23:22 | Add logic to the query planner to only use partial indices if the WHERE clause constrains the search to rows covered by the partial index. This is just infrastructure. The key routine, sqlite3ExprImpliesExpr(), is currently a no-op so that partial indices will never be used. (check-in: 8ca3eac111 user: drh tags: partial-indices) | |
| 22:39 | Slight modifications to path name translation handling for Cygwin. (check-in: 33ba1f4c5d user: mistachkin tags: trunk) | |
| 22:27 | Use a new error code to represent a failure to get the configured temporary directory on Windows. (check-in: c93d891b03 user: mistachkin tags: trunk) | |
| 19:55 | The MAX_PATH constant in windows is measured in characters, so multiple by 3 to get the number of bytes assuming worst-case UTF8 pathnames. (check-in: bb06e15790 user: drh tags: trunk) | |
| 19:05 | Resolve names in CREATE INDEX WHERE clauses and detect errors. Disallow expressions that contain variables, subqueries, or functions. The expression is still not used for anything, however. still unused. (check-in: f2aa7842c8 user: drh tags: partial-indices) | |
| 18:12 | Here begins an experimental branch for exploring the idea of a partial index. This check-in is able to parse a WHERE clause on a CREATE INDEX statement, but does not actually do anythingn with that WHERE clause yet. (check-in: 6794b2dcb4 user: drh tags: partial-indices) | |
|
2013-07-30
| ||
| 15:10 | Reduce the size of the stack required by the codeOneLoopStart() function in where.c. (check-in: eb6d4278b8 user: drh tags: trunk) | |
|
2013-07-29
| ||
| 19:03 | For the MSVC makefile, recompile vdbe.lo and parse.lo first. (check-in: 9e819f0f12 user: mistachkin tags: trunk) | |
| 15:54 | Comment and preprocessor macro cleanup. (check-in: c0809b5e32 user: drh tags: trunk) | |
| 13:51 | In main.mk, always recompile vdbe.o and parse.o first, since changes to either parse.y or vdbe.c will cause all files to be recompiled and if there are syntax errors in vdbe.c or parse.y we want to hit them early in the compile process. (check-in: a94a66d10f user: drh tags: trunk) | |
|
2013-07-25
| ||
| 17:07 | In the command-line shell, work around the fact that popen() and pclose() are not defined in stdio.h. in C89 and later. (check-in: 8bcbb33fd0 user: drh tags: trunk) | |
| 16:41 | Fix a typo in main.c: SQLITE_DEAULT_AUTOMATIC_INDEX -> SQLITE_DEFAULT_AUTOMATIC_INDEX (check-in: cc78e21c77 user: dan tags: trunk) | |
| 16:27 | Enhance the progress handler so that it keeps track of the number of VDBE cycles across sqlite3_step() calls and issues callbacks when the cumulative instruction count reaches threshold. (check-in: 4698a82ef8 user: drh tags: trunk) | |
|
2013-07-24
| ||
| 14:54 | Another attempt at generalizing the URI parsing so that it works with a wider variety of file URIs and yet remains backwards compatible. (check-in: de05eb75ec user: drh tags: uri-enhancement) | |
|
2013-07-23
| ||
| 22:28 | Get the new URI logic working for Windows. (Closed-Leaf check-in: 0165789f08 user: drh tags: uri-enhancement) | |
| 20:54 | Update the URI filename parser to allow (and ignore) authority names in unix and to pass the authority through to the OS on windows, as this appears to be what web-browsers are doing. (check-in: 74c12dee17 user: drh tags: uri-enhancement) | |
|
2013-07-20
| ||
| 00:39 | Merge updates from trunk. (check-in: dd4b77c82a user: mistachkin tags: toTypeFuncs) | |
| 00:34 | Add 'queryplantest' target to the MSVC makefile. (check-in: ad0551e039 user: mistachkin tags: trunk) | |
|
2013-07-19
| ||
| 23:58 | Fixes to test numbering. (check-in: f755b4b21c user: mistachkin tags: trunk) | |
|
2013-07-18
| ||
| 20:28 | Remove unused "codec" code from the command-line shell. (check-in: 37abfe0c1e user: drh tags: trunk) | |
| 18:45 | Improved documentation for sqlite3_set_auxdata(). Ticket [406d3b2ef91c]. (check-in: 62465ecba7 user: drh tags: trunk) | |
| 18:29 | Ensure that all auxiliary data registered by calls to sqlite3_set_auxdata() is destroyed when the VM is halted. (check-in: 153deac8fa user: dan tags: trunk) | |
| 18:28 | Fix a typo in the previous commit. (Closed-Leaf check-in: cd9096e64b user: dan tags: typo) | |
| 17:12 | Ensure that all auxiliary data registered by calls to sqlite3_set_auxdata() is destroyed when the VM is halted. Partial fix for [406d3b2ef9]. DRH adds: Stray text accidentally inserted into vdbe.c just prior to the commit breaks the build. (check-in: 71effa59c9 user: dan tags: typo) | |
| 14:50 | Fix a 8-byte alignment problem in the query planner that might cause problems on sparc when compiled with -m32. (check-in: 5dcffa671f user: drh tags: trunk) | |
| 14:16 | Documentation changes to warn that sqlite3_set_auxdata() might call the destructor even before it returns. Also fix the regexp extension to deal with that case. Ticket [406d3b2ef91c]. (check-in: 7acc8cd32d user: drh tags: trunk) | |
|
2013-07-17
| ||
| 21:08 | Fix copy/paste errors in comments in the transitive_closure virtual table. No changes to code. (check-in: b1b0de29fd user: drh tags: trunk) | |
| 18:12 | Enhance the sqlite3_analyzer tool to give reports on the sizes of individual indices. (check-in: 3b4096cc8a user: drh tags: trunk) | |
| 11:54 | Clear the error string pointer in sqlite3_vtab object after the error string is transferred to SQLite. Ticket [78588b938a11]. (check-in: 64bf8148b8 user: drh tags: trunk) | |
|
2013-07-16
| ||
| 23:26 | Make sure the sqlite3_prepare16 and sqlite3_prepare16_v2 interfaces do not read past a zero-terminator if the nBytes parameter is too large. (check-in: 20dba3a7fb user: drh tags: trunk) | |
| 21:31 | Enhance the query planner so that it looks at multiple solutions to OR expressions in the WHERE clause. (check-in: 5e19d05410 user: drh tags: trunk) | |
|
2013-07-15
| ||
| 17:02 | Add the sqlite3_cancel_auto_extension(X) interface which will undo a prior call to sqlite3_auto_extension(X). (check-in: cdce87eb88 user: drh tags: trunk) | |
|
2013-07-12
| ||
| 21:09 | Make sure the shell does not try to put a zero terminator on the end of an unallocated zero-length string when running ".import" on an empty file. (check-in: 92adaee5bd user: drh tags: trunk) | |
|
2013-07-11
| ||
| 19:04 | Change the description of how sqlite3_progress_handler() works so that the N parameter is "approximate". This aligns with the current implementation. This is a documentation change only. No changes to code. (check-in: 7d829bdea3 user: drh tags: trunk) | |
| 15:31 | Merge recent trunk changes (such as the query_only PRAGMA, the defer_foreign_keys PRAGMA, and the SQLITE_DBSTATUS_DEFERRED_FKS parameter to sqlite3_db_status()) into the sessions branch. (check-in: 8dfc0b78c3 user: drh tags: sessions) | |
| 15:22 | Add the experimental "query_only" pragma. (check-in: 6557c40798 user: drh tags: trunk) | |
| 15:03 | Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. (check-in: 527121ac3c user: drh tags: trunk) | |
| 13:49 | Remove the undocumented sqlite3_foreign_key_check() API and replace it with sqlite3_db_status(db, SQLITE_DBSTATUS_DEFERRED_FKS, ...). Add test cases for the new functionality. (check-in: d39e65fe70 user: drh tags: sessions) | |
| 12:19 | Rename the SQLITE_DeferForeignKeys macro to shorter SQLITE_DeferFKs. Move the "defer_foreign_keys" pragma into the flagPragma() routine. (check-in: 3a2ab74c85 user: drh tags: sessions) | |
| 03:09 | Environment variable names in nmake must be in all uppercase. (check-in: 0328e873f2 user: mistachkin tags: vsix2013) | |
|
2013-07-10
| ||
| 21:33 | More corrections to VS 2013 integration. (check-in: 7a8b0e362b user: mistachkin tags: vsix2013) | |
| 19:53 | Use the VisualStudioVersion variable instead of _MSC_VER. (check-in: 603e9db817 user: mistachkin tags: vsix2013) | |
| 19:39 | More changes to support MSVC 18. (check-in: 29c458e2c2 user: mistachkin tags: vsix2013) | |
| 18:14 | Fix harmless compiler warnings in the progress callback logic. (check-in: 908141d5bf user: drh tags: trunk) | |
| 13:33 | Experimental "PRAGMA query_only=BOOLEAN" statement that is able to turn write capabilities on and off. (Closed-Leaf check-in: ece960c496 user: drh tags: query_only) | |
| 03:05 | Run progress callback checks less frequently in the main VDBE evaluation loop. This makes up for the extra CPU cycles used to increment the cycle counter for SQLITE_STMTSTATUS_VM_STEP. (check-in: 3e8b02011d user: drh tags: trunk) | |
|
2013-07-09
| ||
| 15:56 | Adjust the costs in the xBestIndex function of the spellfix1 virtual table to force the use of the MATCH term if it is available. (check-in: f003bea9fe user: drh tags: trunk) | |
| 13:05 | Pull in all the latest changes from trunk. (check-in: af3ca4c6e5 user: drh tags: sessions) | |

| 03:04 | Make sure the schema is verified prior to processing a "WHERE 0" on the first term of a compound SELECT statement. Fix for ticket [490a4b723562429] (check-in: 52a49cbc16 user: drh tags: trunk) | |
|
2013-07-08
| ||
| 22:33 | Make sure an adequate number of digits are shown for binary-to-text rendering of very small floating point values. (check-in: 776e65f98c user: drh tags: trunk) | |
| 21:12 | Fix an adverse interaction between the IS NOT NULL optimization (available only with SQLITE_ENABLE_STAT3) and the transitive constraint processing. Fix for ticket [d805526eae253] (check-in: 3b30b75b34 user: drh tags: trunk) | |
| 01:27 | Add an optional 5th parameter to the next_char() function that is the collating sequence to use for comparison. (check-in: 9415db6ef2 user: drh tags: trunk) | |
|
2013-07-06
| ||
| 18:07 | Fixes for test cases running in the "mmap" permutation. (check-in: cdb97d41ab user: dan tags: trunk) | |
| 17:57 | Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made). (check-in: 0ae7e75b21 user: dan tags: trunk) | |
