70 check-ins using file main.mk version eab7db27

2016-06-03
13:35
Enhance the sqlite3_load_extension() interface to permit extensions to return SQLITE_OK_LOAD_PERMANENTLY which will prevents unloading when the database connection closes. check-in: 5908aa4d user: drh tags: trunk
2016-06-02
17:44
Add the data= parameter to the CSV virtual table extension. check-in: 76919104 user: drh tags: without-rowid-vtab
16:22
Fix corner cases in the WITHOUT ROWID virtual table logic. check-in: a393bbb9 user: drh tags: without-rowid-vtab

2016-05-31
21:18
An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid. The current check-in almost works, but there are still serious issues. check-in: 49638f18 user: drh tags: without-rowid-vtab
18:44
Add the columns=N parameter to the CSV extension. check-in: 28ebeadd user: drh tags: trunk
18:08
Add the testflags parameter to the csv extension. check-in: b93fb2fe user: drh tags: trunk
16:22
Add the "csv" virtual table for reading CSV files, as an extension in the ext/misc/ subfolder. check-in: 00d3570c user: drh tags: trunk
2016-05-30
08:28
Fix an FTS5 problem (segfault or incorrect query results) with "... MATCH 'x OR y' ORDER BY rank" queries when either token 'x' or 'y' is completely absent from the dataset. check-in: 64ca1a83 user: dan tags: trunk
2016-05-28
18:53
Experimental change to allow virtual tables to take advantage of LIKE, REGEXP and GLOB terms that are part of OR expressions within WHERE clauses. Closed-Leaf check-in: 242507b4 user: dan tags: vtab-experimental
17:45
Remove an unnecessary malloc from the vfsstat extension. check-in: 24f258c2 user: drh tags: trunk
17:23
Enhance the sqlite3_load_extension() interface to permit extensions to return SQLITE_OK_LOAD_PERMANENTLY which will prevent the extensions from unloading when the database connection closes. Closed-Leaf check-in: d3f99a5e user: drh tags: load-permanently
15:22
Enhance "PRAGMA compile_options" so that it shows the version of the compiler used to generate the executable, for common compilers. check-in: 6a0f2009 user: drh tags: trunk
15:09
Update the amalgamation-tarball configure script so that it can use header file "readline/readline.h" with library file "libedit". check-in: cbf72b04 user: dan tags: trunk
15:03
Enhance the sqlite3_load_extension() API so that the first parameter (the "db" parameter) can be NULL. An extension that is not associated with any database connection remains loaded for the life of the process. Closed-Leaf check-in: 3a461043 user: drh tags: persistent-extensions
14:53
Add the vfsstat.c loadable extension - a VFS shim that measures the amount of I/O, and an eponymous virtual table that is used to extract and view the measurements. check-in: 0987487d user: drh tags: trunk
00:13
Clang can define _MSC_VER in some circumstances; therefore, check for Clang first. Closed-Leaf check-in: 3f710bc3 user: mistachkin tags: ctimeCompiler
2016-05-27
21:13
Check for Clang before GCC. check-in: 7c2cd4b0 user: mistachkin tags: ctimeCompiler
20:30
Remove surplus quotation marks from the COMPILER= compile_options setting for Clang. check-in: 5c966f20 user: mistachkin tags: ctimeCompiler
19:34
Remove surplus quotation marks from the COMPILER= compile_options setting for GCC. check-in: 664c132d user: drh tags: ctimeCompiler
18:09
Add basic compiler information to the results of 'PRAGMA compile_options'. check-in: d734e2df user: mistachkin tags: ctimeCompiler
12:30
Improvements to WHERE-clause debug tracing. Show TK_MATCH expressions and show more details on WhereTerm traces. check-in: 71087c12 user: drh tags: trunk
04:10
Fix Lemon so that it actually works with -DYYSTACKDEPTH=0. check-in: a9be4c2d user: drh tags: trunk
01:07
Fix the Lemon-generated parser so that it compiles with -DYYSTACKDEPTH=0. It does compile now, but there are subtle issues still. check-in: 28d439f8 user: drh tags: trunk
2016-05-26
20:56
Add a new OP_SeekRowid opcode, that combines the functions of OP_MustBeInt and OP_NotExists. This makes the code slightly smaller and faster. check-in: ffe80a1b user: drh tags: trunk
2016-05-25
18:53
Add the libvers.c tool in the tool/ subdirectory. check-in: 2a41f098 user: drh tags: trunk
2016-05-24
18:55
Enhance Lemon and the parser template so that it can once again build parsers that have no unreachable branches. check-in: 41fd46e2 user: drh tags: trunk
18:50
Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. check-in: 61e239bc user: drh tags: trunk
16:20
Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. check-in: 37de3eab user: dan tags: trunk
00:40
Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. check-in: 3b28b68e user: drh tags: trunk
2016-05-23
21:56
Use a pointer to the top of the stack rather than an index into the stack in the Lemon-generated parser template, for about 6.6% parser performance gain. check-in: 3c2a7705 user: drh tags: trunk
19:02
Avoid a minor error message when running RTREE without an sqlite_stat1 table. check-in: 276e92f5 user: drh tags: trunk
18:27
Fix the rtreeG.test test case. Closed-Leaf check-in: 9589e937 user: drh tags: tree-stat1-fix
18:12
Fix RTREE so that it does not run queries against the sqlite_stat1 if that table does not exist. check-in: 48526a2f user: drh tags: tree-stat1-fix
18:06
Remove an extra "finish_test" from the end of rtreeC.test. check-in: bfbb6dd8 user: drh tags: tree-stat1-fix
16:16
Improve the error messages generated by the rtree module when a constraint fails. check-in: 3ad2531e user: dan tags: trunk
16:15
Lemon enhancement: avoid unnecessary reduce actions that convert one non-terminal into another but have no side effects. check-in: a86e782a user: drh tags: trunk
14:24
Fix comment typos and improve clarity of presention in Lemon. The output should be identical. check-in: b91a5b82 user: drh tags: trunk
00:10
Update the configure script with additional hints on the location of tclConfig.sh, hints needed by the latest versions of Xcode. check-in: 90411a28 user: drh tags: trunk
2016-05-21
23:25
More tweaks to improve the performance of the insert logic, slightly. check-in: dec13075 user: drh tags: trunk
20:03
Simplify the sqlite3BtreeInsert() interface by gathering the five arguments describing the content to be inserted into the new BtreePayload structure, and thus reducing the number of parameters from eight to four. check-in: 55f348cd user: drh tags: trunk
19:10
Remove some unused legacy code from the btree insert logic. check-in: 2ce11667 user: drh tags: trunk

Add the shell-script used for routine performance testing. check-in: 8e366f18 user: drh tags: trunk
2016-05-20
23:51
Add a simple TCL script for summing cachegrind information for each VDBE opcode. check-in: 96cf821b user: drh tags: trunk
21:40
Another optimization on the OP_Column opcode. check-in: 1765672c user: drh tags: trunk
20:58
Fix typo in comment. check-in: 9db8f214 user: mistachkin tags: trunk
19:51
Slight performance improvement in the OP_Column opcode. check-in: 5c157474 user: drh tags: trunk
18:09
Remove the sqlite3PagerClearCache() routine, which does not accomplish anything useful. check-in: f250166b user: drh tags: trunk
15:53
Performance optimization and size reduction on the freeP4() routine. check-in: 4dc56e86 user: drh tags: trunk
15:24
Increase the version number to 3.14.0 since we are already making significant code changes. check-in: 1a0d0576 user: drh tags: trunk
15:15
Use sqlite3VdbeAddOp0() to code OP_Expire, to save a few bytes. check-in: 3d55d24d user: drh tags: trunk
14:54
Optimizations to link list merge sort code in vdbesort.c, pcache.c, and rowset.c. Resulting binaries are 10 bytes smaller and use 0.03% fewer CPU cycles. check-in: 9033afbb user: drh tags: trunk
14:11
For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. check-in: 559733b0 user: drh tags: trunk
13:44
Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. Closed-Leaf check-in: ed1b30dc user: drh tags: orderby-limit
12:22
Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. check-in: 645bd696 user: drh tags: trunk
00:21
A few simple test cases for the ORDER BY LIMIT optimization. check-in: 08849eab user: drh tags: orderby-limit
2016-05-19
22:40
Appears to work now. Needs test cases, more comments, and code optimization. check-in: 990fe50c user: drh tags: orderby-limit
22:13
In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. check-in: 852d1eda user: drh tags: orderby-limit
19:31
Fixup comments on wctrlFlags value definitions. check-in: 58b516e8 user: drh tags: trunk
18:56

Performance improvement in the OP_Column opcode. check-in: 4737cadc user: drh tags: trunk
16:21
Add test cases to test some fts3/4 edge case behaviour surrounding the '*' character. check-in: 1f577e1f user: dan tags: trunk
11:12
Small size reduction and performance improvement in the OP_Column opcode. check-in: 0d773061 user: drh tags: trunk
2016-05-18
21:03
Add the "scrub" utility program that simultaneously backs-up a live database and erases all deleted content. check-in: c981ab2a user: drh tags: trunk
2016-05-17
21:17
Enhance the scrub utility program so that it does a FULL checkpoint prior to starting the backup, to ensure that the database file content matches what needs to be backed up without having to look at the WAL file. Closed-Leaf check-in: ab1c5ce5 user: drh tags: scrub-backup
17:11
Merge the latest changes from trunk. check-in: 5021dfe1 user: drh tags: scrub-backup
