01:08
Begin implementing a new system of upper bounds on the capabilities of SQLite. By clearly defining the upper bounds, we make those upper bounds explicitly testable. This check-in is just infrastructure. The upper bounds are not yet enforced. (CVS 3941) check-in: 93b623b2 user: drh tags: trunk
2007-05-07

Fix compilation and testing with OMIT_INCRBLOB defined. (CVS 3923) check-in: a0f8adc6 user: danielk1977 tags: trunk
18:36
Test interaction of incremental io and other database writes. (CVS 3922) check-in: 4516416b user: danielk1977 tags: trunk
18:30
Change incremental vacuum to be triggered by a pragma rather than a command. We have a lot to learn about this yet and we do not want to paint ourselves into a corner by commiting to specific syntax too early. (CVS 3921) check-in: b13e497a user: drh tags: trunk
17:07
Tighter compression of the keyword hash table. (CVS 3920) check-in: 68121676 user: drh tags: trunk
16:14
Optional parameter in the INCREMENTAL VACUUM statement specifies how many pages to vacuum from the database. (CVS 3919) check-in: ed713f9c user: drh tags: trunk
14:36
Get tests working with SQLITE_OMIT_AUTOVACUUM=1. (CVS 3918) check-in: b94d39e4 user: drh tags: trunk
14:14
Make "incremental" a fallback token so that you can set "auto_vacuum=incremental" without having to quote the "incremental". (CVS 3917) check-in: 9d7a2e2b user: drh tags: trunk
13:15
Eliminate all uses of sprintf() and strcpy(). These were not being misused. But getting rid of them removes a library dependency. And it avoids warnings from the OpenBSD compiler. Ticket #2336. (CVS 3916) check-in: ba4845b3 user: drh tags: trunk
12:05
Test cases and corrections to IO and malloc() error handling in incremental blob IO functions. (CVS 3915) check-in: 641e5528 user: danielk1977 tags: trunk
12:01
Fix a formatting errror in I/O logging. (CVS 3914) check-in: 2d37687a user: drh tags: trunk
11:59
Add compile-time option -DSQLITE_MIXED_ENDIAN_64BIT_FLOAT=1 that uses mixed-endian doubles. This is needed on ARM7 to make database file formats compatible with all other processors. Tickets #2278 and #2335. (CVS 3913) check-in: 2a178d0c user: drh tags: trunk
08:32
Rework accessPayload() function for clarity. (CVS 3912) check-in: 42d07c70 user: danielk1977 tags: trunk
2007-05-03
20:06
fix from Gentoo for allowing TCLLIBDIR to be overridden in env (CVS 3911) check-in: e54a49e2 user: vapier tags: trunk

Test some more incremental IO error cases. (CVS 3910) check-in: 64705410 user: danielk1977 tags: trunk
17:18
Improvements to I/O tracing output. Require -DSQLITE_ENABLE_IOTRACE when compiling shell.c in order to link in the I/O tracing capability. (CVS 3909) check-in: 8a43e167 user: drh tags: trunk
16:55
Get the amalgamation builder working with incremental I/O. (CVS 3908) check-in: 92b53601 user: drh tags: trunk
16:31
Test cases and minor bugfixes for incremental blob APIs. (CVS 3907) check-in: e12c5223 user: danielk1977 tags: trunk
13:11
Fix a bug where accessPayload() was calling PagerWrite() on the wrong page handle. Ticket #2332. (CVS 3906) check-in: cf9eeba7 user: danielk1977 tags: trunk
13:02
Use memmove() instead of memcpy() when moving between memory regions that might overlap. Ticket #2334. (CVS 3905) check-in: 678d672b user: drh tags: trunk
11:43
Minor bugfixes for incrblob mode. (CVS 3904) check-in: b84d597c user: danielk1977 tags: trunk
11:43
Minor bugfixes for incrblob mode. (CVS 3903) check-in: db54a946 user: danielk1977 tags: trunk
2007-05-02
17:54
Allow CREATE TABLE to occur while other queries are running. DROP TABLE is still prohibited, however, since we do not want to delete a table out from under an running query. (CVS 3902) check-in: 5b4bf1fc user: drh tags: trunk
17:48
Combine the internal btree functions BtreePutData() and getPayload(). (CVS 3901) check-in: a100a530 user: danielk1977 tags: trunk
16:51
More fixes and improvements to the zeroblob() mechanism. (CVS 3900) check-in: 83ab2501 user: drh tags: trunk
16:48
Cache the location of overflow pages in cursors used for incremental blob IO. (CVS 3899) check-in: 349f1ea7 user: danielk1977 tags: trunk
15:36
Fix an invalid UTF8 encoding in the tests for the trim function. (CVS 3898) check-in: 4dbbfff4 user: drh tags: trunk
13:30
Add support for zero-blobs to the OP_MakeRecord opcode. First test cases of zeroblob functionality. (CVS 3897) check-in: e6d560dd user: drh tags: trunk
13:16
Use the pointer-map pages to make the incremental blob API more efficient. (CVS 3896) check-in: 93a3bf71 user: danielk1977 tags: trunk
02:08
Fix some compiler warnings. Add the (untested) zeroblob() SQL function. (CVS 3895) check-in: 6f4f8ba7 user: drh tags: trunk
01:34
Begin adding the zeroblob API to support incremental blob i/o. (CVS 3894) check-in: 7a01836d user: drh tags: trunk
2007-05-01
18:25
Enable prefix-search in query-parsing and snippet generation. If the character immediately after the end of a term is '*', that term is marked for prefix matching. Modify term comparison in snippetOffsetsOfColumn() to respect isPrefix. fts2n.test runs prefix searching through some obvious test cases. (CVS 3893) check-in: 7c4c6592 user: shess tags: trunk
17:49
First approximation of incremental blob IO API. (CVS 3892) check-in: c444836e user: danielk1977 tags: trunk
17:14
Modify loadSegmentLeavesInt() to correctly handle prefix searching. The new function docListUnion() is used to accumulate a union of the hits for the matching terms, which will be merged across segments using docListMerge(). (CVS 3891) check-in: 72c79630 user: shess tags: trunk
16:59
The pager takes the sector size to be the larger of the sector size reported by sqlite3OsSectorSize() and the page size. (CVS 3890) check-in: e5e6af55 user: drh tags: trunk
2007-04-30
22:09
Propagate prefix flag through implementation of doclist query code. Also implement correct prefix-handling for traversal of interior nodes of segment tree. A given prefix can span multiple children of an interior node, and from there the branches need to be followed in parallel. (CVS 3889) check-in: cae844a0 user: shess tags: trunk
21:39
Fix a potential segfault following a malloc() failure during a call to sqlite3_prepare() where the nBytes parameter is positive but less than the length of the input SQL string. (CVS 3888) check-in: 27bf3fc3 user: drh tags: trunk
17:52
Lift docListMerge() call out of loadSegmentLeavesInt() for prefix search. Doclists from multiple prefix matches will need a union merge function, which will have to logically happen across a segment before doclists are merged between segments. (CVS 3887) check-in: 7ddb8266 user: shess tags: trunk
16:55
Try to avoid reading pages when moving overflow chains to the free-list. (CVS 3886) check-in: 8cccec68 user: danielk1977 tags: trunk
2007-04-28
15:47
Add some tests (and 2 resulting bug fixes) to incr vacuum mode. (CVS 3885) check-in: 89b1b3f8 user: danielk1977 tags: trunk
2007-04-27
22:02
Break interior-node and leaf-node readers apart in loadSegment(). Previously, the code looped until the block was a leaf node as indicated by a leading NUL. Now the code loops until it finds a block in the range of leaf nodes for this segment, then reads it using LeavesReader. This will make it easier to traverse a range of leaves when doing a prefix search. (CVS 3884) check-in: 9466367d user: shess tags: trunk
21:59
Internationalize the TRIM functions. Ticket #2323. (CVS 3883) check-in: ff1f4e74 user: drh tags: trunk
21:24
Lift code to traverse interior nodes out of loadSegment(). Refactoring towards prefix searching. (CVS 3882) check-in: 25935db7 user: shess tags: trunk
21:02
Refactor fts2 loadSegmentLeaf() in preparation for prefix-searching. Prefix-searching will want to accumulate data across multiple leaves in the segment, using LeavesReader instead of LeafReader is the first step in that direction. (CVS 3881) check-in: 22ffdae4 user: shess tags: trunk
17:16
Make sure sqlite3_value_bytes() does not reformat the content after a call to sqlite3_value_blob(). Add documentation to explain this hazard. Add many new tests. Ticket #2321. (CVS 3880) check-in: e92bd97a user: drh tags: trunk
07:55
Extra tests for incremental vacuum. (CVS 3879) check-in: 40ba6493 user: danielk1977 tags: trunk
07:05
Modifications to btree integrity check so that it can be run inside a transaction after an incr vacuum. (CVS 3878) check-in: 4d4180d6 user: danielk1977 tags: trunk
01:18
The replace() function should return NULL if the second argument is an empty string. Ticket #2324. (CVS 3877) check-in: e6a0c90d user: drh tags: trunk
2007-04-26
14:42
Add largely untested code for the incremental vacuum function. (CVS 3876) check-in: f6a6d2b8 user: danielk1977 tags: trunk
12:11
In the pager, load the content of pages which were initialized with noContent==1 if they are subsequently requested with noContent==0. (CVS 3875) check-in: d0745a43 user: drh tags: trunk
2007-04-25
18:23
Fix segfaults that can occur if a malloc failure happens just before a built-in function calls sqlite3_value_text(). (CVS 3874) check-in: 9cb0ed6e user: drh tags: trunk
15:42
Disable tests in misc7 that do not work on windows due to limitations of the windows file system. (CVS 3873) check-in: 66646d6f user: drh tags: trunk
12:07
Version 3.3.17 (CVS 3872) check-in: 16979f45 user: drh tags: trunk
12:06
Fix a file descriptor leak in the exclusive2 test script. (CVS 3871) check-in: 2d2e68da user: drh tags: trunk
11:42
Preparing for the release of 3.3.17. (CVS 3870) check-in: e278c4ef user: drh tags: trunk
11:32
Fix duplicate test IDs in the test suite. No changes to code. Ticket #2319. (CVS 3869) check-in: 0935cdf8 user: drh tags: trunk
11:28
Fix a bug in the sqlite3_changes() function reported on the mailing list. (CVS 3868) check-in: 58ea768c user: drh tags: trunk
2007-04-24
17:35
This fixes a missed case in check-in (3866). Do not apply patch (3866) without also applying this patch. (CVS 3867) check-in: 66c2fa08 user: drh tags: trunk
17:27
When the write_version flag in the database header is larger than what the library understands, make the database read-only. The old behavior was to make the database unreadable. (CVS 3866) check-in: 10648e99 user: drh tags: trunk
2007-04-23
23:56
Get the build working with -DSQLITE_OMIT_UTF16=1. Ticket #2314. (CVS 3865) check-in: 25c1c7aa user: drh tags: trunk
2007-04-21
16:37
Add the ability to turn the FTS2 module into an amalgamation. (CVS 3864) check-in: 94374654 user: drh tags: trunk
2007-04-20
12:22

2007-04-19
18:36
Fix bug in fts2 handling of OR queries. When one doclist ends before the other, the code potentially tries to read past the end of the doclist. http://www.sqlite.org/cvstrac/tktview?tn=2309 (CVS 3862) check-in: dfac6082 user: shess tags: trunk
14:48
Better fix than (3860) for the same problem. (3860) could leave file-handles open in some circumstances. (CVS 3861) check-in: 5ad64533 user: danielk1977 tags: trunk
14:28
Fix a crash that can occur if an error happens in a virtual table xSync() function. (CVS 3860) check-in: d1afdd8c user: danielk1977 tags: trunk
12:30
Comment changes in the ioerr tests. No changes to code. (CVS 3859) check-in: b7ed0e1e user: drh tags: trunk
11:09
Fix a bug whereby sqlite3_prepare_v2() could return both an out-of-memory error and a valid statement handle. (CVS 3858) check-in: 8795d11c user: danielk1977 tags: trunk
00:24
Get the build working with SQLITE_OMIT_SHARED_CACHE. Ticket #2307. (CVS 3857) check-in: b623538c user: drh tags: trunk
2007-04-18
17:07
Fix a && where & was intended. This is a real problem, but it would be very difficult to devise a test case where it might lead to an unexpected result. Ticket #2306. (CVS 3856) check-in: 7f9f0444 user: drh tags: trunk
17:04
Better handle malloc() failures in the "echo" virtual table test module. (CVS 3855) check-in: 6881f921 user: danielk1977 tags: trunk
16:45
The sqlite3_step() routine reports SQLITE_ERROR after a commit failure, not SQLITE_DONE. This fix only effects the legacy sqlite3_prepare() interface. It already worked correctly with sqlite3_prepare_v2(). (CVS 3854) check-in: 165dc72d user: drh tags: trunk
15:33
Version 3.3.16 (CVS 3853) check-in: 8c6b5adb user: drh tags: trunk
14:47
Fix an assertion failure caused by (3851). (CVS 3852) check-in: 24683f1d user: danielk1977 tags: trunk
14:24
Minor changes (mainly to assert() macros) to handle malloc failure in vtab operations. (CVS 3851) check-in: 175156d1 user: danielk1977 tags: trunk
13:49
Bump the version number and update documents in preparation for 3.3.16. (CVS 3850) check-in: 852100a3 user: drh tags: trunk
2007-04-17
08:32
Avoid reloading the db schema after a failed OP_VerifyCookie if the in-memory schema cookie already matches the database file. (CVS 3849) check-in: 61c1d06d user: danielk1977 tags: trunk
