Combine the OP_Column and OP_DfltValue opcodes. (CVS 4664) check-in: c30f8206 user: danielk1977 tags: trunk
07:54
Change OP_OpenRead and OP_OpenWrite so that the database number is read from the P3 operand, not the stack. (CVS 4663) check-in: 35da261d user: danielk1977 tags: trunk

Add opcodes OP_ResultRow and OP_RegMakeRec which are register-based equivalents to OP_Callback and OP_MakeRecord. Use the new opcodes. (CVS 4656) check-in: 4c7f35da user: drh tags: trunk
13:05
Remove a surplus OP_Close from delete.c. Fixes a problem with (4654). (CVS 4655) check-in: 03cc91b3 user: drh tags: trunk

04:41
Add some extra tests for the recent trigger compilation optimization. (CVS 4653) check-in: de54dad8 user: danielk1977 tags: trunk
00:34
Begin setting a foundation on which to convert the VM from a stack-based to a register-based machine. Everything is still mostly stack based with this check-in.

2008-01-01
19:02
Optimize trigger compilation to avoid populating the OLD.* and NEW.* pseudo-tables with data that will never be used. Some testing to come. (CVS 4651) check-in: e08a33ed user: danielk1977 tags: trunk

05:49
Define SQLITE_CORE=1 at the start of the amalgamation file for the benefit of any extension source code (i.e. fts3) appended to it. Ticket #2858. (CVS 4649) check-in: 6dea8c16 user: danielk1977 tags: trunk

13:39
Add experimental pragma "quick_check", a reduced version of integrity_check that runs without most of the overhead of the full integrity_check. (CVS 4645) check-in: 2ddc8d72 user: danielk1977 tags: trunk
13:18
Mem3.c enhanced so that an allocation of N bytes only requires (N+11)&~7 bytes instead of (N+15)&~7 bytes of heap storage. Minimum heap usage per allocation is still 16 bytes. 8-byte alignment is preserved. (CVS 4644) check-in: d027f91c user: drh tags: trunk
2007-12-27
15:12
Fix a race condition that can occur when reloading the database schema in shared-cache mode. (CVS 4643) check-in: b37babef user: danielk1977 tags: trunk

2007-12-19
09:20

2007-12-17
16:20
When SQLITE_MAX_SQL_LENGTH is 0, disable the limit. Make the default 0. Once again build the sqlite3 CLI from individual source files so that it can be built on systems that lack tclsh. Tickets #2845 and #2846. (CVS 4636) check-in: 07aeca3b user: drh tags: trunk

Change to the crash simulator to give better diagnostics in case it runs out of memory while using the mem3.c allocator. (CVS 4632) check-in: 0d5747db user: drh tags: trunk
16:11
Fix a typo in the previous check-in. Also simplify a line in select.c. (CVS 4631) check-in: 86f45d7b user: drh tags: trunk

21:54
Change all instances of "it's" in comments to either "its" or "it is", as appropriate, in case the comments are ever again read by a pedantic grammarian. Ticket #2840. (CVS 4629) check-in: 4e91a267 user: drh tags: trunk

Adjust the test suite to account for recent changes related to #2822. Most changes are related to English language error messages only. (CVS 4622) check-in: 2f88b9b3 user: danielk1977 tags: trunk
03:45
ORDER BY in a compound SELECT will first match against the left-most SELECT. If there is no match there, it begins working its way to the right. (CVS 4621) check-in: 56063ec8 user: drh tags: trunk
02:45
Towards getting ORDER BY to match against the correctin columns. This version only looks at the left-most column in a compound SELECT. That is the correct thing to do, but not what SQLite has historically done. (CVS 4620) check-in: bbddf16a user: drh tags: trunk
2007-12-12
22:24

Fix some problems similar to #2832, but caused by triggers instead of an OR REPLACE clause. (CVS 4615) check-in: ee98ae17 user: danielk1977 tags: trunk
14:46
Test file containing minimal example of bug #2832. (CVS 4614) check-in: ed2e61a9 user: danielk1977 tags: trunk
12:25
Fix database corrupting code generation error for UPDATE OR REPLACE. ticket #2832. Still need to add test cases and additional defensive logic to avoid future occurrences of similar problems. (CVS 4613) check-in: 18e10f81 user: drh tags: trunk
12:00
Add a new OP_StackDepth opcode to help detect VDBE stack leaks early, before they cause damage. For diagnostics in ticket #2832. (CVS 4612) check-in: 3fd6a267 user: drh tags: trunk
04:38
Fix test numbering in tkt2822.test. Ticket #2830. (CVS 4611) check-in: 8fe8e9c4 user: danielk1977 tags: trunk
2007-12-11

18:51
Further modifications to do with ORDER BY and compound SELECT queries. Related to ticket #2822. (CVS 4606) check-in: 0d9b0e6e user: danielk1977 tags: trunk
18:07
Fix a macro in func.c that causes problems for the amalgamation. (CVS 4605) check-in: 6adbe91e user: drh tags: trunk
17:55
Fix a bug in the compilation procedures for the Linux shared library that includes the TCL bindings. (CVS 4604) check-in: d384810a user: drh tags: trunk

21:10
Better resolution of ORDER BY terms in compound queries. Candidate solution for ticket #2822. Needs more testing and documentation before going final. (CVS 4602) check-in: 62a78d21 user: drh tags: trunk
18:01
Strengthen the tests for aggregate functions in GROUP BY clauses. Changes to test cases only. No changes to code. (CVS 4601) check-in: 4be8e676 user: drh tags: trunk
17:55
Fix a bug in the debugging printf logic. (CVS 4600) check-in: 1d6a9f5f user: drh tags: trunk
2007-12-07
23:47
Change prefix search from O(N*M) to O(NlogM). The previous code linearly merged the doclists, so as the accumulated list got large, things got slow (the M term, a fucntion of the number of documents in the index). This change does pairwise merges until a single doclist remains. A test search of 't*' against a database of RFC text improves from 1m16s to 4.75s. (CVS 4599) check-in: feef1b15 user: shess tags: trunk
18:55

13:26
Use the specified buffer length, not the maximum buffer length in unixFullPathname() and related functions. (CVS 4595) check-in: f015a387 user: drh tags: trunk
02:42
Continuing work on the C/C++ interface requirements that appears as comments in sqlite.h.in. (CVS 4594) check-in: 2130e712 user: drh tags: trunk
2007-12-05
18:05
Begin adding requirements numbers to the C/C++ interface documentation. (CVS 4593) check-in: ae1936aa user: drh tags: trunk
01:38

2007-12-04
16:54
Make sure statement journals are initiated when doing DROP operations (since the DROP might fail after sqlite_master changes). Also make sure statement journals are initiated if there are pending SELECT statements. Ticket #2820. (CVS 4591) check-in: bf34284f user: drh tags: trunk
13:41
Fix a bug in the TCL code for sqlite3_analyzer. (CVS 4590) check-in: 7c2cf454 user: drh tags: trunk
13:22
Clarify the operation of sqlite3_blob_close() in the API documentation. Ticket #2815. (CVS 4589) check-in: 78f359df user: drh tags: trunk
2007-12-03
21:52
Do not require os_other.h if compiling with -DOS_OTHER=1. (CVS 4588) check-in: 96ec3903 user: drh tags: trunk
2007-12-02
11:46
When parsing CREATE INDEX statements from the sqlite_master table, do not search the temp database schema for the corresponding table. Only consider the database for which the schema is being parsed. Ticket #2817. (CVS 4587) check-in: e6f02aa5 user: danielk1977 tags: trunk
2007-12-01
19:25
Another fix to Makefile.in for mingw. (CVS 4586) check-in: cfaeb025 user: drh tags: trunk
19:23
Beginning attempts at casting the sqlite.h.in documentation into formal requirements. (CVS 4585) check-in: 2ea78d2c user: drh tags: trunk
