Suppress compiler warnings. Fix a bug in IO error detection on windows. (CVS 3564) check-in: daed2bab user: drh tags: trunk
02:00
In the btree.c, when releasing the page1 lock, first make sure the pager has not reset and released the lock already. This fixes a bug introduced by (3549). (CVS 3563) check-in: 36a2db96 user: drh tags: trunk
01:58
Get threadtest2.c working again after being long neglected. (CVS 3562) check-in: 06216d0d user: drh tags: trunk

23:36
Additional changes in the pager and os interface layers to fix problems that might be contributing to recently observed database corruption. (CVS 3549) check-in: a593d574 user: drh tags: trunk
15:34
Make sure that the database size cache in the pager is invalidated whenever the database is unlocked. A stale value in the database size cache can result in database corruption on a heavily loaded system running autovacuum. (CVS 3548) check-in: 6806b9ec user: drh tags: trunk
2007-01-02
18:41
Update the vtab_err test to check for -DSQLITE_MEMDEBUG=1 and skip the tests if missing. Pager is more careful to clear its file size cache. Remove an assert() in VDBE that might fail on a corrupt database file. (CVS 3547) check-in: bf1afd01 user: drh tags: trunk
2006-12-22
20:33
OS/2 change: add safeguard to be able to use SQLite loaded into high memory on OS/2 when compiled with GCC 3.3 or later. Currently, this is only used when building within the Mozilla source tree. (CVS 3546) check-in: 720189b8 user: pweilbacher tags: trunk
2006-12-21
22:38
Disable extension loading by default. At some point we should change the configure script to detect the presence of dlopen() automatically and add the appropriate library to the link. But that requires a working version of autoconf, which I do not have. Ticket #2124. (CVS 3545) check-in: 87a9ee07 user: drh tags: trunk
03:20
More fixes to the microsoft code-page nightmare... (CVS 3544) check-in: 0b47d880 user: drh tags: trunk

01:29
Move the shared-library loading routines into the OS portability layer, thus enabling the os_win.c code to handle the character encoding confusion of win95/nt/ce. Ticket #2023. (CVS 3541) check-in: a1bcc6de user: drh tags: trunk
00:46
Change a parameter type from "int" to "DWORD" in the windows interface. Ticket #2122. (CVS 3540) check-in: cca1eb3d user: drh tags: trunk

Patch to get extension loading working on wince. Ticket #2023. (CVS 3537) check-in: a81f3ddf user: drh tags: trunk
03:24
The query optimizer does a better job of optimizing out ORDER BY clauses that contain the rowid or which use indices that contain the rowid. Ticket #2116. (CVS 3536) check-in: f245f5c2 user: drh tags: trunk
02:15
Allow constraint names on DEFAULT values in a table definition. Ticket #2109. (CVS 3535) check-in: 893d58c2 user: drh tags: trunk
2006-12-19

2006-12-18
18:34
Speed improvement: do not journal or rollback pages that are pulled out of the freelist. (CVS 3531) check-in: 4dffc4c3 user: drh tags: trunk
14:12
Updates to the "Distinctive Features" document. (CVS 3530) check-in: c734585e user: drh tags: trunk
2006-12-16
16:25
Query optimizer enhancement: In "FROM a,b,c left join d" allow the C table to be reordered with A and B. This used to be the case but the capability was removed by (3203) and (3052) in response to ticket #1652. This change restores the capability. (CVS 3529) check-in: 7393c81b user: drh tags: trunk
2006-12-14
01:06
Fix a bug in lemon that leads to an assertion fault given an invalid grammar. The bug and this fix do not effect on SQLite. Ticket #2107. (CVS 3528) check-in: f2ad230f user: drh tags: trunk
2006-11-30
13:06
Change the table_info pragma so that it returns NULL for the default value if there is no default value. Ticket #2078. (CVS 3527) check-in: 5f21c3a5 user: drh tags: trunk
13:06
Improvements to the new performance tests. (CVS 3526) check-in: 27f56c20 user: drh tags: trunk
13:05
Fix indentation typo in btree.c. (CVS 3525) check-in: 5d61486f user: drh tags: trunk
2006-11-29
23:41
Drop a couple variables which are no longer used anywhere. (CVS 3524) check-in: 08c2cc0e user: shess tags: trunk
21:03
Test that terms longer than interior nodes work correctly. A bug prior to fts2.c r1.10 meant that such large terms caused an eventual stack overflow. (CVS 3523) check-in: 66581162 user: shess tags: trunk
20:53
Added the speed1.test script (CVS 3522) check-in: 30355dfb user: drh tags: trunk
05:17
http://www.sqlite.org/cvstrac/tktview?tn=2046    The virtual table interface allows for a cursor to field multiple xFilter() calls. For instance, if a join is done with a virtual table, there could be a call for each row which potentially matches. Unfortunately, fulltextFilter() assumes that it has a fresh cursor, and overwrites a prepared statement and a malloc'ed pointer, resulting in unfinalized statements and a memory leak.    This change hacks the code to manually clean up offending items in fulltextFilter(), emphasis on "hacks", since it's a fragile fix insofar as future additions to fulltext_cursor could continue to have the problem. (CVS 3521) check-in: 18142fdb user: shess tags: trunk
01:02
Delta-encode terms in interior nodes. While experiments have shown that this is of marginal utility when encoding terms resulting from regular English text, it turns out to be very useful when encoding inputs with very large terms. (CVS 3520) check-in: c8151a99 user: shess tags: trunk
2006-11-23
21:09
Improvements to the speed tests recently added to the test suite. (CVS 3519) check-in: 272c1a6e user: drh tags: trunk
11:59
Fix a typo in the OMIT_AUTORIZATION in expr.c. (CVS 3518) check-in: 3dea7fbe user: drh tags: trunk
11:58
Make the pager sector size configurable at compile-time. (CVS 3517) check-in: 6221cf4f user: drh tags: trunk
09:39
Add performance tests to the test suite. (CVS 3516) check-in: 270c745d user: drh tags: trunk
2006-11-20
16:21
Fix the ".dump" command in the shell. Ticket #2072. Also ticket #2065. (CVS 3515) check-in: 9fdc2496 user: drh tags: trunk
2006-11-18
20:20
Make sure VACUUM cleans up after itself. Ticket #2071. (CVS 3514) check-in: 2fdc147d user: drh tags: trunk
00:12
Store minimal terms in interior nodes. Whenever there's a break between leaf nodes, instead of storing the entire leftmost term of the rightmost child, store only that portion of the leftmost term necessary to distinguish it from the rightmost term of the leftmost child. (CVS 3513) check-in: f6e0b080 user: shess tags: trunk
2006-11-17
21:12
Refactoring groundwork for coming work on interior nodes. Change LeafWriter to use empty data buffer (instead of empty term) to detect an empty block. Code to validate interior nodes. Moderate revisions to leaf-node and doclist validation. Recast leafWriterStep() in terms of LeafWriterStepMerge(). (CVS 3512) check-in: f30771d5 user: shess tags: trunk
2006-11-13
21:09
Delta-encode docids. This is good for around 22% reduction in index size with DL_POSITIONS. It improves performance about 5%-6%. (CVS 3511) check-in: 9b6d413d user: shess tags: trunk
21:00
Require a minimum fanout for interior nodes. This prevents cases where excessively large terms keep the tree from finding a single root. A downside is that this could result in large interior nodes in the presence of large terms, which may be prone to fragmentation, though if the nodes were smaller that would translate into more levels in the tree, which would also have that problem. (CVS 3510) check-in: 64b7e340 user: shess tags: trunk
20:15
Allow backing tables to be missing on dropping fts table. Fixes http://www.sqlite.org/cvstrac/tktview?tn=1992,35 . (CVS 3509) check-in: 9628a61a user: shess tags: trunk
2006-11-11
01:31
The uninitialized file descriptor from the unixFile structure is passed to sqlite3DetectLockingStyle in allocateUnixFile rather than the file descriptor passed in. This was causing the locking detection on NFS file systems to behave somewhat randomly and the result was locks were not respected and data loss could occur. (CVS 3508) check-in: b9dd16ef user: aswift tags: trunk
2006-11-09
15:18
Update the documentation to talk about the new sqlite3_prepare_v2() API. (CVS 3507) check-in: d9e14b61 user: drh tags: trunk
00:24
First cut at adding the sqlite3_prepare_v2() API. Test cases added, but more testing would be useful. Still need to update the documentation. (CVS 3506) check-in: f1efae92 user: drh tags: trunk
2006-11-08
12:25
Make the .exit and .quit commands work again in the shell. Ticket #2056. (CVS 3505) check-in: f39978ef user: drh tags: trunk
2006-11-07
15:02
Fix a typo in os_win.c. Ticket #2055. (CVS 3504) check-in: d309680e user: drh tags: trunk
2006-11-06
21:20
Use the difference between the SQLITE_IOERR_SHORT_READ and SQLITE_IOERR_READ returns from sqlite3OsRead() to make decisions about what to do with the error. (CVS 3503) check-in: 6324ea81 user: drh tags: trunk
15:10
Fix a bug in the optimizer that was causing it to miss an OR optimization opportunity. (CVS 3502) check-in: 9bf153b5 user: drh tags: trunk
2006-11-01
12:20
Modify Makefile.in to install sqlite3ext.h. (CVS 3501) check-in: 35c8c478 user: drh tags: trunk

Remove dead code from btree.c. Ticket #2050. (CVS 3500) check-in: dbd0125c user: drh tags: trunk
2006-10-31
21:27
Change the default temp file prefix to be "sqlite" spelled backwards. Tickets #2049 et al. (CVS 3499) check-in: a19ce5c1 user: drh tags: trunk
21:16
Change the default prefix for temporary files so that it no longer contains the text "sqlite". In this way, perhaps we will not get so many false bug reports such as ticket #2049, #1989, and #1841. (CVS 3498) check-in: 7ce48000 user: drh tags: trunk
18:13
Fix a pair of memory leaks. These were turned up by running valgrind memcheck with various 10k doc insert, update, delete, and query tests. (CVS 3497) check-in: 3cd9b64b user: shess tags: trunk
18:08
Make the command-line shell ".dump" command more resilient in the face of database corruption. (CVS 3496) check-in: ebd44f0b user: drh tags: trunk
2006-10-30
13:37
Changes to support non-ASCII characters in win95 filenames. Ticket #2047. (CVS 3495) check-in: 9fa3ae58 user: drh tags: trunk
2006-10-28
00:28
Enhance the optimizer so that IS NULL can use an available index. (CVS 3494) check-in: 64762a9d user: drh tags: trunk
2006-10-27
14:21
Fix the ".dump" command in the command-line shell so that it shows TRIGGERs and VIEWs. Ticket #2044. (CVS 3493) check-in: 58171a41 user: drh tags: trunk
14:06
Changes directed toward optimizing IS NULL terms in WHERE clauses. (CVS 3492) check-in: 4d336e9e user: drh tags: trunk
2006-10-26
18:15
Bring CVS output into more commonly accepted practice. Tickets #2030, #1573. Add command-line options -bail and ".bail" commands. Default behavior is to continue after encountering an error. Ticket #2045. (CVS 3491) check-in: 517712d6 user: drh tags: trunk
14:25
Command-line shell enhancements. Bail out when errors are seen in non-interactive mode. Override isatty() using -interactive or -batch command-line options. Report line number in error messages. Tickets #2009, #2045. (CVS 3490) check-in: 3baa04cf user: drh tags: trunk
00:41
Empty queries should get no results. My recent change ( http://www.sqlite.org/cvstrac/chngview?cn=3486 ) broke test fts2a-5.3. This change should make the expected result more obvious. (CVS 3489) check-in: cde383eb user: shess tags: trunk
00:04
Make memset() uses less error-prone. http://www.sqlite.org/cvstrac/tktview?tn=2036,35 describes some cases where we were passing memset() a length which was the sizeof a pointer, rather than the structure pointed to. Instead, wrap this idiom up in CLEAR() and SCRAMBLE() macros. (CVS 3488) check-in: 5878add0 user: shess tags: trunk
2006-10-25
23:22
Remove unreferenced local variable. (CVS 3487) check-in: 2d3b2219 user: shess tags: trunk
21:00
Replace the DocList and DocListReader structures. The new structures distinguish reading from a static buffer from writing to a dynamic buffer. This allows n-way doclist merging, and in-place merging of segment leaf nodes, which together cut segment merge times in half. (CVS 3486) check-in: af5bfb98 user: shess tags: trunk
20:27
Test to force edge cases in query logic. Basically, exercise code to handle lack of hits correctly. (CVS 3485) check-in: 2cb59033 user: shess tags: trunk
05:21
Don't store empty segments. When inserting empty strings, the code was writing out a segment made up of a single leaf node containing the \0 header. LeafReader assumed that leaf nodes always contained at least one term, so assertions would fail.    While it would be possible to support reading and merging empty segments, there's no reason to do so. While this change could have been done in writeZeroSegment(), I put it in leafWriterFlush() so that it would work right if segmentMerge() created an empty segment, which could happen with future changes to how deleted documents are handled. (CVS 3484) check-in: fed79bee user: shess tags: trunk
2006-10-19
23:36
dup fts1 tests and edit for fts2. fts1porter.test omitted because it depends on being able to poke through to %_term table. (CVS 3482) check-in: 2806c341 user: shess tags: trunk
23:28
Add tests for delete and update in fts1. (CVS 3481) check-in: b01c4371 user: shess tags: trunk
20:27
fts2 support for testing. These are a prelude to adding some test scripts. (CVS 3480) check-in: 004ad194 user: shess tags: trunk
01:58
When converting UTF8 or UTF16 strings, change overlong strings and other illegal codes to 0xFFFD. Ticket #2029. (CVS 3479) check-in: 0c6736df user: drh tags: trunk

Fix a problems that arise if malloc() fails while compiling SELECT statements within a TRIGGER. (CVS 3478) check-in: ee4894b4 user: drh tags: trunk
2006-10-13
15:34
Make sure the names of all expressions in compound SELECT statements used as subqueries are correctly resolved. Ticket #2018. (CVS 3477) check-in: b886eaa3 user: drh tags: trunk
12:25
Avoid expanding %d contained in the action of a lemon parser rule. Ticket #1063. This is a fix for lemon only. It does not effect SQLite. (CVS 3476) check-in: 81daedcf user: drh tags: trunk
11:55
Removing debugging printf from the porter stemmer code. Ticket #2016. (CVS 3475) check-in: 7a08c627 user: drh tags: trunk
2006-10-12
23:15
Convert fts2 to store data in a way which allows for much faster updates. Groups of documents form segments which are encoded in a btree layered over a table of blocks, with various tricks to make merges fast. This performs 20x-25x faster than fts1 when loading the Enron corpus, and is only slightly slower for queries. (CVS 3474) check-in: 85272b2f user: shess tags: trunk
2006-10-11
17:19
Bug fix: named local variable lockStyle as lockingStyle in SQLITE_ENABLE_LOCKING_STYLE block in allocateUnixFile (CVS 3473) check-in: aa0b96c3 user: aswift tags: trunk
2006-10-10
23:22
Fix leaky symbols. With this change, fts1 and fts2 can both be statically linked. (CVS 3472) check-in: 5e8bbb85 user: shess tags: trunk

Fix incorrect doclist initialization in term_select_all(). docListRestrictColumn() generates a DL_POSITIONS doclist, which means that after the first doclist is processed, the second doclist is initialized as DL_POSITIONS, but with DL_POSITIONS_OFFSETS data. (Note that DL_DEFAULT is now DL_POSITIONS, which masks this bug.) (CVS 3467) check-in: 144e3f11 user: shess tags: trunk

Fix a build problem around sqlite3_overload_function. Only affects so/dll builds. (CVS 3435) check-in: 791d7093 user: shess tags: trunk
00:06
Implemented UPDATE for full-text tables.    We handle an UPDATE to a row by performing an UPDATE on the content table and by building new position lists for each term which appears in either the old or new versions of the row. We write these position lists all at once; this is presumably more efficient than a delete followed by an insert (which would first write empty position lists, then new position lists). (CVS 3434) check-in: 757fa224 user: adamd tags: trunk
2006-09-21
20:56
When gathering a doclist for querying, don't discard empty position lists until the end; this allows empty position lists to override non-empty lists encountered later in the gathering process. This fixes #1982, which was caused by the fact that for all-column queries we weren't discarding empty position lists at all. (CVS 3433) check-in: 111ca616 user: adamd tags: trunk

02:12
Modify FTS1 so that the "magic" column has the same name as the virtual table. Offsets are retrieved using a special "offsets" function whose first argument is the magic column. Snippets will ultimately be retrieved in the same way. (CVS 3427) check-in: 5e35dc1f user: drh tags: trunk

The FTS1 tables have a new automatic column named "offset" that returns a string containing byte offset information for all matching terms. Also added a large test case based on SQLite mailing list entries. (CVS 3417) check-in: f25cfa1a user: drh tags: trunk

Implementation of "column:" modifiers in FTS1 queries. (CVS 3411) check-in: 820634f7 user: drh tags: trunk
15:20
Module spec parser enhancements for FTS1. Now able to cope with column names in the spec that are SQL keywords or have special characters, etc. Also added support for additional control lines. Column names can be followed by a type specifier (which is ignored.) (CVS 3410) check-in: adb780e0 user: drh tags: trunk

Fix the FTS1 test cases and add new tests. Comments added to the FTS1 code. (CVS 3409) check-in: 528036c8 user: drh tags: trunk
02:18
Allow virtual tables to contain multiple full-text-indexed columns. Added a magic column "_all" which can be used for querying all columns in a table at once.    For now, each posting list stores position/offset information for multiple columns. We may implement separate posting lists for separate columns at some future point. (CVS 3408) check-in: 366a70b0 user: adamd tags: trunk

23:45
Add support for IF EXISTS on CREATE/DROP TRIGGER/VIEW. Ticket #1899. (CVS 3406) check-in: e4fe736c user: drh tags: trunk
21:39
Re-use deleted rowids for new segments. This has a somewhat surprising impact on performance, I believe because it keeps the index smaller (by keeping rowids smaller), and also because it improves locality in the table (deleting a row means we've already touched the pages leading to that rowid). (CVS 3405) check-in: 2f5f6290 user: shess tags: trunk
11:13
Get VACUUM working with virtual tables. (CVS 3404) check-in: d5ffef38 user: drh tags: trunk

2006-09-10
17:31
Add pzErr parameters to the xConnect and xCreate methods of virtual tables in order to provide better error reporting. This is an interface change for virtual tables. Prior virtual table implementations will need to be modified and recompiled. (CVS 3402) check-in: f44b8bae user: drh tags: trunk
17:08
Add a new zErrMsg field to the sqlite3_vtab structure to support returning error messages from virtual table constructors. This change means that virtual table implementations compiled as loadable extensions for version 3.3.7 will need to be recompile for version 3.3.8 and will not be usable by both versions at one. The virtual table mechanism is still considered experimental so we feel justified in breaking backwards compatibility in this way. Additional interface changes might occurs in the future. (CVS 3401) check-in: 36693a5c user: drh tags: trunk
03:34
Add some simple test cases for the OR and NOT logic of the fts1 module. Fix lots of bugs discovered while developing these test cases. (CVS 3400) check-in: 70bcff02 user: drh tags: trunk

Add support for OR and NOT terms in fts1. (CVS 3399) check-in: ae502657 user: drh tags: trunk
2006-09-08
17:00
Write doclists using a segmented technique to amortize costs better. New items for a term are merged with the term's segment 0 doclist, until that doclist exceeds CHUNK_MAX. Then the segments are merged in exponential fashion, so that segment 1 contains approximately 2*CHUNK_MAX data, segment 2 4*CHUNK_MAX, and so on. (CVS 3398) check-in: b6b93a33 user: shess tags: trunk
12:49
Add HAVE_GMTIME_R and HAVE_LOCALTIME_R flags and use them if defined. Unable to modify the configure script to test for gmtime_r and localtime_r, however, because on my SuSE 10.2 system, autoconf generates a configure script that does not work. Bummer. Ticket #1906 (CVS 3397) check-in: 862302ea user: drh tags: trunk
