2009-05-13
07:52
When locking a database file, check if any backup objects need to be restarted even if the page cache is empty. Ticket #3858. (CVS 6632) check-in: 90309008 user: danielk1977 tags: trunk
2009-05-12
18:00
Remove debugging comments left in the prior check-in by mistake. (CVS 6631) check-in: 82070560 user: drh tags: trunk
17:46
Move the sqlite3MinimumFileFormat() routine from build.c over to alter.c since alter.c is the only code that uses it. Additional changes and cleanup to build.c to facility coverage testing. (CVS 6630) check-in: 6fe3750a user: drh tags: trunk
13:35
Make sure the SQLITE_OPEN_EXCLUSIVE flag is ignored by sqlite3_open_v2(). That flag is to be used by the VFS interface only. Ticket #3855. (CVS 6629) check-in: c37f0279 user: drh tags: trunk
00:40
Tweaks to build.c to facilitate coverage testing. (CVS 6628) check-in: 6572b438 user: drh tags: trunk

23:38
If a virtual table constructor returns SQLITE_NOMEM, set the mallocFailed flag in the corresponding database connection to insure that the error is propagated back to the top layer. (CVS 6627) check-in: 5635666f user: drh tags: trunk
20:53
Rework the logic that generates a schema for tables created using "CREATE TABLE ... AS SELECT ...". Instead of trying to copy the raw datatype string from the right-hand side, just make the type one of TEXT, INT, REAL, NUM, or nothing. This is much simpler than trying to parse and quote datatype strings. Other minor implifications to build.c are bundled with this change. (CVS 6626) check-in: 33cf8359 user: drh tags: trunk
18:22
Enhance the parser to allow nested parentheses in the module argument of a CREATE VIRTUAL TABLE statement. (CVS 6625) check-in: 93772bd7 user: drh tags: trunk

15:17
Change sqlite_blob_open() so that it zeros the output pBlob pointer when it fails. The other sqlite3_blob interfaces accept a NULL pointer as input. (CVS 6622) check-in: 999d507b user: drh tags: trunk
00:18
Changes to the trigger.c module that facilitate full coverage testing. (CVS 6621) check-in: 567ccc68 user: drh tags: trunk

2009-05-03
20:23
Changes to facility full coverage testing of util.c. (CVS 6597) check-in: a6122990 user: drh tags: trunk

Simplifications to the uniqueness constraint failure error message generation code. (CVS 6595) check-in: 8f3cac76 user: drh tags: trunk
13:29
Remove the aFKey hash table, which was not being used. Simplify the FKey object. Simplify the hash.c module since the copyKey parameter formerly used only by aFKey is now no longer required. (CVS 6594) check-in: 80c43a35 user: drh tags: trunk
12:02
Reduce the size of an integer literal in rowhash.tcl so that the test is able to run with the default TCL installation on Mac OS 10.5. (CVS 6593) check-in: 2229acce user: drh tags: trunk
10:03
When a cursor points at the last entry of an intkey btree after an insert, leave it there (instead of moving it to the tree root node). This speeds up statements of the form "INSERT INTO ... SELECT ..." that use auto-generated rowids. (CVS 6592) check-in: 9950c0a7 user: danielk1977 tags: trunk
07:36
Do not reset the cursor before seeking it in sqlite3BtreeInsert(). This speeds up INSERT operations that use auto-generated rowid values. (CVS 6591) check-in: 20c4acc2 user: danielk1977 tags: trunk
00:28
When checking indices for xfer compatibility, compare collating sequences by string, not by pointer. (CVS 6590) check-in: 7d2b80c7 user: drh tags: trunk
2009-05-01
21:13
Record within the Token structure itself whether or not the token has been dequoted. This steals one bit from the length of a token and thus limits the size of tokens to 1GiB. (CVS 6589) check-in: 12bcb03d user: drh tags: trunk
15:17
Fix an error message that is generated if the number of columns do not match on an INSERT into a virtual table with hidden columns. (CVS 6588) check-in: 795b453c user: drh tags: trunk
13:16
Update PRAGMA integrity_check so that it treats SQLITE_IOERR_NOMEM errors from underlying components the same as SQLITE_NOMEM errors. (CVS 6587) check-in: 26444f2a user: drh tags: trunk
10:55
Change lock2.test so that it does not enter a busy loop if the child process exists unexpectedly. (CVS 6586) check-in: 164a7f5a user: danielk1977 tags: trunk

Documentation updates for sqlite3_set_authorizer(). No changes to code. (CVS 6579) check-in: 41f39c31 user: drh tags: trunk
13:30
Disallow attaching the same database multiple times to the same db connection in shared cache mode, since doing so leads to deadlock. (CVS 6578) check-in: 715f14f1 user: drh tags: trunk
12:25
Fix apparent typo on exclusive.test in the (6575) check-in. (CVS 6577) check-in: 95d22405 user: drh tags: trunk
12:25
Changes sqlite3TempInMemory() to take a const parameter. (CVS 6576) check-in: aa29a14c user: drh tags: trunk
09:10
When SQLite is configured to use in-memory temp files (either by setting SQLITE_TEMP_STORE during compilation or using the temp_store pragma at run time), store statement/savepoint journals in memory also. Ticket #3825. (CVS 6575) check-in: 38f8c5a1 user: danielk1977 tags: trunk
05:40
Fix a memory leak introduced in the previous check-in. (CVS 6574) check-in: f082bf36 user: drh tags: trunk
05:19
Take care not to leave a zombie attached database if the attachment fails due to an encoding mismatch. Update attach logic to always use dynamically allocated error message strings. (CVS 6573) check-in: a6cb4002 user: drh tags: trunk
01:22
Remove always-true tests from attach.c. In btree.c, always test the return from sqlite3PagerSetPagesize() since it might return SQLITE_NOMEM. (CVS 6572) check-in: 8bf60b24 user: drh tags: trunk
00:11
Remove an always-true test from delete.c. Move the sqlite3OpenTable() routine from delete.c to insert.c since it is not used in delete.c. (CVS 6571) check-in: 71756dc8 user: drh tags: trunk
2009-04-29
18:12
Fixed compile for MSVC; removed compiler warnings; changes for NDEBUG build; minor code tweaks. (CVS 6570) check-in: e98b1242 user: shane tags: trunk

11:50
Fix a case in where.c where a crash can follow a malloc failure. Also modify test code in test8.c to check a return code that was being dropped (causing a test in vtab_err.test to fail). (CVS 6567) check-in: 9664e2b6 user: danielk1977 tags: trunk
11:31
Add a version of cellSizePtr() that is faster than using sqlite3BtreeParseCellPtr(). This speeds up balance_nonroot(). (CVS 6566) check-in: e8f7f7b7 user: danielk1977 tags: trunk
06:27
Simplify a conditional expression in btree.c. (CVS 6565) check-in: fc3a5ac2 user: danielk1977 tags: trunk
2009-04-28
18:00
Fix an out-of-order test number in blob.test. Cosmetic change. No changes to code. Ticket #3830. (CVS 6564) check-in: e8556542 user: drh tags: trunk

Fix asserts in hash.c so that zero-length symbols can be used. (CVS 6563) check-in: fe9f00aa user: drh tags: trunk
16:37
When testing with TEMP_STORE=3 and the test pcache, only run 20 iterations in trans.test. Otherwise the test pcache runs out of memory. (CVS 6562) check-in: 0799b729 user: danielk1977 tags: trunk
16:35
Remove an unused function declaration from hash.h. (CVS 6561) check-in: fcf70bb8 user: drh tags: trunk
15:48
Further adjustment to rowhash.test to account for rowid collisions. (CVS 6560) check-in: 94a23f99 user: danielk1977 tags: trunk
15:43
Simplifications to the symbol table implementation in hash.c. For very small symbol tables (less than 10 entries) a simple linked list is used instead of a hash table. Number of hash table buckets is limited to prevent large allocations. (CVS 6559) check-in: 5c737835 user: drh tags: trunk
15:35
Have sqlite3_create_collation() return MISUSE if passed an encoding value other than SQLITE_UTF8, SQLITE_UTF16LE, SQLITE_UTF16BE, SQLITE_UTF16 or SQLITE_UTF16_ALIGNED. (CVS 6558) check-in: 7975b6f2 user: danielk1977 tags: trunk

12:08
Another fix to the same assert as in (6555). It can also fail after a malloc error. (CVS 6556) check-in: e096f90a user: danielk1977 tags: trunk
11:10
Fix an assert that could fail after a parse error in expr.c. (CVS 6555) check-in: a37d1174 user: danielk1977 tags: trunk
05:27
Avoid changing the pager journal-mode once a write-transaction is open, even if no database pages have been modified. (CVS 6554) check-in: ad8aba3e user: danielk1977 tags: trunk
04:51
Add test cases for sqlite3_complete with an EXPLAIN QUERY PLAN on a CREATE TRIGGER statement. Ticket #3828. (CVS 6553) check-in: 6b86b40e user: drh tags: trunk
04:47
Make sure sqlite3_open16() always zeros the db return pointer if SQLite initialization fails. (CVS 6552) check-in: 057c7d17 user: drh tags: trunk
04:46
Enhance sqlite3_complete() so that it understands EXPLAIN QUERY PLAN. Ticket #3828. Testing is done in TH3. (CVS 6551) check-in: 3ac1b15f user: drh tags: trunk
2009-04-27
18:46
Bring the documenation and implementation of sqlite3_collation_needed() into agreement. Use a more efficient implementation of sqlite3ErrStr(). sqlite3_result_error_code() now calls sqlite3ErrStr() if no prior error string was set. (CVS 6550) check-in: cb9af829 user: drh tags: trunk
2009-04-25
08:39
Tests for the new asynchronous IO API. (CVS 6549) check-in: 11b2564e user: danielk1977 tags: trunk
2009-04-24
20:32
Add another test case for the "x IS NULL" uniqueness problem of ticket #3824. No changes to code. This just double-checks that everything is working now. (CVS 6548) check-in: 3ceae357 user: drh tags: trunk
18:06
Dequote the "from" table in a FOREIGN KEY definition (affects the output of "pragma foreign_key_list). Fix for #3800. (CVS 6547) check-in: 600482d1 user: danielk1977 tags: trunk
15:46
Get rid of the special RowSet processing in where.c and move that into clients. Added the WHERE_DUPLICATES_OK option to eliminate an unnecessary RowSet during DELETE with a WHERE clause containing ORs. (CVS 6546) check-in: 98606bee user: drh tags: trunk
14:51
Make sure that the optimizer realizes that an "x IS NULL" contraint does not necessarily give a single-row result even on a UNIQUE index. Ticket #3824. (CVS 6545) check-in: 207335fd user: drh tags: trunk
10:13
Make selecting the asynchronous IO file-locking mode a runtime operation. Still untested. (CVS 6544) check-in: 577277e8 user: danielk1977 tags: trunk
09:27
Improve comments and documentation of the asynchronous IO VFS module. (CVS 6543) check-in: 92bc6be2 user: danielk1977 tags: trunk
2009-04-23
19:08
os_win.c, winOpen(), changed to handle the SQLITE_OPEN_EXCLUSIVE flag and sharing modes in the same manner as os_unix.c. Ticket #3821. (CVS 6542) check-in: 18fef3fc user: shane tags: trunk
18:42
Updated misc. test scripts for Windows testing with gcc/cygwin; (CVS 6541) check-in: 1e2c7159 user: shane tags: trunk
18:41
Remove some incorrect async tests; (CVS 6540) check-in: 03af25b3 user: shane tags: trunk
14:58
Move the asynchronous IO code from src/test_async.c to ext/async/. Refactor it to be a standalone module and to support windows. (CVS 6539) check-in: e71fb0fb user: danielk1977 tags: trunk
13:22
Rework the column-cache mechanism to be more robust (and more correct). The column-alias cache is currently disabled, (CVS 6538) check-in: dd4d67a6 user: drh tags: trunk
2009-04-22
17:15
Eliminate the OP_VRowid opcode. The regular OP_Rowid now work for both regular and virtual tables. (CVS 6537) check-in: ecbef450 user: drh tags: trunk
15:32
Change the OP_Rowid opcode so that a deferred OP_Seek is pending, it simply pulls the rowid from the deferred seek target and does not actually move the cursor or do a seek. Other where.c cleanups. (CVS 6536) check-in: 1c508a99 user: drh tags: trunk
02:15
Remove the rowhash object from the code. Rowset now fills its role. (CVS 6535) check-in: e963bed0 user: drh tags: trunk
00:47
Extend the Rowset object to contain all the capabilities of Rowhash in addition to its legacy capabilities. Use Rowset to replace Rowhash. In addition to requiring less code, This removes the 2^32 result row limitation, uses less memory, and gives better bounds on worst-case performance. The Rowhash implementation has yet to be removed. (CVS 6534) check-in: b101cf70 user: drh tags: trunk
2009-04-21
18:20
Move RowHashBlock.nUsed to RowHash.nUsed. Fix a typo in a comment in test_async.c. (CVS 6533) check-in: 799d31d9 user: danielk1977 tags: trunk
