2011-04-05
22:08
Suppress many harmless compiler warnings, mostly signed/unsigned comparisons within asserts or unused parameters in extensions. (check-in: 3eeb0ff7 user: drh tags: trunk)
19:27
Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. (check-in: 51039b35 user: drh tags: trunk)
19:26
Simplifications to the sqlite3ResetInternalSchema() logic to eliminate unreachable branches. (check-in: a4c3ac98 user: drh tags: trunk)

Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. (check-in: a89f24e2 user: drh tags: trunk)
17:31
Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. (check-in: 242ce7cf user: drh tags: trunk)

When committing a WAL transaction, do not write any pages to the WAL file with page numbers greater than the size of the database image in pages. (check-in: 311d0b61 user: dan tags: trunk)
14:22
Fix a documentation typo. (check-in: d25c17ef user: drh tags: trunk)
13:12
Merge the scheme-parse-refactor changes into trunk: (1) added sqlite3SchemaMutexHeld() asserts, (2) Use -1 instead of 0 to mean "all" in sqlite3ResetInternalSchema(), and other cosmetic changes. (check-in: 5db4511d user: drh tags: trunk)
12:25
Fix the P4_TRANSIENT constant so that it works correct - so that it really makes a copy of the string for the P4 argument. Use P4_TRANSIENT wherever appropriate. Change P4_STATICs of schema names to P4_TRANSIENT. (check-in: bf664b20 user: drh tags: trunk)
11:26
Improved comment on the sqlite3SrcListLookup function. (check-in: bcbc9ff5 user: drh tags: trunk)

Add a description of access rules for the Schema object and lots of asserts to verify that the access rules are followed. (check-in: ae8374af user: drh tags: schema-parse-refactor)
15:38
Add the "--start=[permutation:][testfile]" option to tester.tcl. For starting quick.test or all.test at the nominated permutation and/or test file. (check-in: a97e8505 user: dan tags: trunk)
14:05
Merge test_syscall.c fix from the trunk. (check-in: 1e1a23cc user: dan tags: schema-parse-refactor)
14:03
Have test_syscall.c include "sqliteInt.h". Otherwise the SQLITE_OS_UNIX symbol may not be defined correctly. (check-in: fda8fadd user: dan tags: trunk)
13:40
Rename sqlite3SchemaFree() to sqlite3SchemaClear() to more accurately reflect its function. (check-in: 71d74400 user: drh tags: schema-parse-refactor)

07:05
Changes to oserror.test and syscall.test so that they work with the in-memory journal permutation test. (check-in: 4e996f36 user: dan tags: trunk)
03:27
Suppress unused parameter warnings in sqlite3VdbeEnter() and related routines. (check-in: f8e98ab3 user: drh tags: trunk)
00:14
Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk)
2011-04-03
18:19
Make sure that the constant 1 is cast to yDbType before shifting to create an attached database mask. This check-in is a follow-up and fix to the [7aaf8772274422] change that increases the maximum number of attached databases from 30 to 62. (check-in: e2a09ea7 user: drh tags: trunk)

Change the name of the "tAttachMask" datatype to "yDbMask". (check-in: 3d6f2e82 user: drh tags: trunk)
17:00
Avoid returning SQLITE_NOTFOUND when the unix xSetSystemCall interface is invoked with NULL passed as the second argument, even if all the default system calls are already installed. (check-in: 3b91eaaa user: dan tags: trunk)
16:50
When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. (check-in: 211d5dde user: drh tags: schema-parse-refactor)
16:28
Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. (check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor)
09:44
Fix a race condition in OP_ParseSchema. (check-in: 71a799b0 user: dan tags: trunk)

18:12
Add a script that will break the amalgamation source file up into 4 or 5 smaller source files, each 32K lines or fewer, and a single "sqlite3-all.c" source file that #includes the others. (check-in: 5d34e64d user: drh tags: trunk)
17:53
Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk)
16:50
When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk)
15:15
Ensure that it is not possible to add a column to a system table using ALTER TABLE. (check-in: d9707ef8 user: dan tags: trunk)

14:04
Test cases for ANALYZE-index. (Closed-Leaf check-in: 365896cb user: drh tags: analyze-idx)
13:29
Move a variable declaration inside an #ifdef to avoid a compiler warning. (check-in: 7a6d05df user: drh tags: trunk)
11:56
In os_unix.c, do not return SQLITE_BUSY to SQLite following an error in fcntl(F_UNLCK), regardless of the value of errno. (check-in: ff6dfe6e user: dan tags: trunk)

Add tests and fixes for SELECT multiplex_control(op, val); (check-in: fee9734c user: shaneh tags: multiplex-enhancements)
05:31
Additional test cases; Round chunk size up to a multiple of max page size; (check-in: 36e364a3 user: shaneh tags: multiplex-enhancements)
02:03
Change the ANALYZE command so that it will accept an index name as its argument and only reanalyze that one index. A quick smoke-test works. Need to study the implications to the query planner and test corner cases. (check-in: c8f9edd9 user: drh tags: analyze-idx)
2011-03-30
21:03
Updates to multiplex.test script; misc. bug fixes; (check-in: c41ff235 user: shaneh tags: multiplex-enhancements)

The first simple test-case appears to be working now. (check-in: dd41155b user: drh tags: word-fuzzer)
15:40
Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk)
14:08
Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer)
10:04
Fix a problem in the unix VFS implementation of xNextSystemCall(). Also some typos that prevent compilation when HAVE_POSIX_FALLOCATE is defined. (check-in: bc6cce81 user: dan tags: trunk)
05:06
In-progress changes - do not use; Removed prefix support; Added file control interface to enable/disable and adjust chunk size; added app-def function for same; (check-in: bc02d0c1 user: shaneh tags: multiplex-enhancements)
01:47
Fix the documentation for the sqlite3_column_*_name() functions to describe that the information can be invalidated when a prepared statement is reprepared by the first invocation of an sqlite3_step() for a particular execution cycle. (check-in: 7270f80a user: drh tags: trunk)
2011-03-28
19:10

Added most of the logic. Simple test runs without segfaulting but does not give the correct answer. (check-in: fb4c31ea user: drh tags: word-fuzzer)
15:05
Skeleton code for the word-fuzzer virtual table. (check-in: ea3a4ee1 user: drh tags: word-fuzzer)
2011-03-24
17:43
Minor change to sqlite3Utf8Read() to make consistent with READ_UTF8() usage and avoid implementation defined usages of <<. Added some additional UTF-8 test cases. (check-in: 7173b392 user: shaneh tags: trunk)
17:37
Fix problem with tableapi.test on Windows. (check-in: 69fe0c87 user: shaneh tags: trunk)
01:34
The changes to fix [f7b4edece25c9948] mean that the schema is always loaded whenever a prepared statement is running. This means that a couple of branches can be eliminated and one operand of OP_ParseSchema can be removed. (check-in: b6e268fc user: drh tags: trunk)
2011-03-23
22:54
Fix a signed/unsigned comparison compiler warning. (check-in: c81da6f9 user: drh tags: trunk)

2011-03-17
16:45
Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. (check-in: 54bacb95 user: drh tags: trunk)
01:58
Comment enhancement to better explain the logic in the "x IS NULL" optimization. (check-in: 869f8947 user: drh tags: trunk)
01:34
Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. (check-in: 23531768 user: drh tags: trunk)
2011-03-16
18:54
Additional interpretation of flags and constants in the VFS trace output. (check-in: 3e984195 user: drh tags: trunk)

Add the -vfstrace option to the usage error message in the shell. (check-in: baca45c5 user: drh tags: trunk)
16:56
Add the VFS-trace shim. (check-in: f49a9ef3 user: drh tags: trunk)
2011-03-15

Make the "unix-excl" VFS work exactly like "unix" if the database file is read-only. (check-in: d9846834 user: drh tags: trunk)
18:35
Fix an out-of-order variable declaration in shell.c. (check-in: 72570846 user: drh tags: trunk)
04:45
Allow multiplex file names to be preceeded by prefix of the form ":multiplex:chunksize:maxchunks:" Still work to be done, though it compiles and prefixes are ignored. (check-in: cfa4a2f7 user: shaneh tags: multiplex-enhancements)
02:55

2011-03-14
13:54
Merge the unix-excl VFS into the trunk. This merge also adds the -vfs option to the command-line shell. (check-in: 3934b004 user: drh tags: trunk)
2011-03-12
18:10
In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl)
17:02
Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c32 user: drh tags: unix-excl)
04:58
More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. (check-in: b8699943 user: shaneh tags: trunk)
2011-03-11
16:15

2011-03-10
21:48
Simplification of tests and more added for SQLITE_OMIT_UNIQUE_ENFORCEMENT tests. (check-in: 75a38411 user: shaneh tags: trunk)
21:13
Skip unique constraint enforcement if compiled with SQLITE_OMIT_UNIQUE_ENFORCEMENT. (check-in: ba85bf8c user: shaneh tags: trunk)
03:54
Minor clean-up of previous mem5 allocator fix. (check-in: 36438423 user: shaneh tags: trunk)
2011-03-09
21:36
Fix issue with mem5 allocator when min request size is larger thatn 2^30. (check-in: d7dae06f user: shaneh tags: trunk)
21:02
Omit unnecessary OP_Next and OP_Prev operators when uniqueness constraints guarantee that the code will only make one pass through the loop. (check-in: f000c9b2 user: drh tags: trunk)
11:04
Updates to the OS/2 implementation from Rich Walsh. (check-in: dc46156a user: drh tags: trunk)
2011-03-08
16:39
Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk)
14:05
Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d3 user: drh tags: trunk)
13:06
Fix two compiler warnings. No functional code changes. (check-in: c829868a user: drh tags: trunk)
02:38
Fix additional cases of possible signed integer overflow, especially with regard to negation. (check-in: 2d5800bd user: drh tags: trunk)

21:54
Another minor simplification brought to light by clang. (check-in: 3bfbf026 user: drh tags: trunk)
21:28
Remove dead code identified by the clang static analyzer. (check-in: 01a79d5a user: drh tags: trunk)
2011-03-05
21:41
Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fd user: drh tags: trunk)
20:59
Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk)
13:54
Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk)
2011-03-04
15:43

Fix the ANALYZE command so that it takes collating sequences into account when gathering index statistics. (check-in: a5867cfc user: drh tags: trunk)
17:57
The ANALYZE command now counts at all rows of an index, even those containing NULL values. A valid sqlite_stat1 entry is created even if the index contains nothing but NULLs. (check-in: 824c8dd3 user: drh tags: trunk)
2010-12-29
18:24
Have testfixture invoke C routine Zipvfs_Init() when creating a new interpreter if SQLITE_ENABLE_ZIPVFS is defined. (check-in: 430635da user: dan tags: trunk)

Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined and the constant folding optimization is disabled using sqlite3_test_control(). Problem introduced by [ad8bc68197f2b4] but we missed it prior to the 3.7.4 release due to taking shortcuts and skipping tests in the release checklist. (check-in: 70a3d817 user: drh tags: trunk)
02:06
Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database. This prevents a concurrent write to the database from resetting the wal-index out from under the WalIterator of the checkpoint as it is initializing. (check-in: cf86affc user: drh tags: trunk)
2010-12-15
21:02

2010-12-03
18:57
Remove an over-zealous call to memAboutToChange() from OP_MustBeInt. OP_MustBeInt will never invalidate the Mem.z pointer so the memAboutToChange() call is not necessary. (check-in: 841cf7a7 user: drh tags: trunk)
15:41
Version 3.7.4 release candidate 1 (check-in: 2e800cb8 user: drh tags: trunk)

Remote the SQLITE_OMIT_GLOBALRECOVER macro - it is subsumed by SQLITE_OMIT_DEPRECATED. Add support to sqlite3_compileoption_used() for SQLITE_OMIT_WAL. (check-in: 21a2db90 user: drh tags: trunk)
2010-07-06

11:26
Do not do the *-closeallfiles test for notify2.test. It uses multiple threads. (check-in: fb09152d user: dan tags: trunk)
10:55
Before calling Tcl_ExitThread() in a multi-threaded test, call Tcl_DoOneEvent() as many times as necessary to handle any queued events. (check-in: b3399b40 user: dan tags: trunk)
09:29

2010-07-05
21:00
Modify the VFS xAccess() method on winNT so that it returns false for an exists test of a zero-length file. This makes the windows VFS work the same as the unix VFS. (check-in: ec35f254 user: drh tags: trunk)
19:13
Simplify the previous commit by removing the pagerCheckForOrDeleteWAL() wrapper. (check-in: a1324d12 user: dan tags: trunk)
19:03
Allocate a buffer containing the full path-name to the associated WAL file when a pager is created. This saves having to construct a new buffer each time a new read-transaction is opened and SQLite checks for the existance of a WAL file. (check-in: 3053a4ad user: dan tags: trunk)
17:43
When rolling back page 1 from a journal, restore the "nReserve" setting in case it has been corrupted by a prior crash. (check-in: c0d124da user: drh tags: trunk)
14:54

12:54
Call Tcl_ExitThread() from within threads created using Tcl_CreateThread(). Not doing so causes notifier related errors on OSX. (check-in: 684eae66 user: dan tags: trunk)
05:54
Add any files specified as part of the QUICKTEST_INCLUDE environment variable to the set of test files run as part of "make test". Release testing uses this trick. (check-in: a40a6e7d user: dan tags: trunk)

05:56
Change code in OP_Rewind to avoid a valgrind warning following an error in the btree layer. This change does not fix any bug, just a warning. (check-in: 4f62dbcf user: dan tags: mistake)
01:44
Fix a buffer overrun in the where.c. Problem detected by valgrind. (check-in: 15bb6233 user: drh tags: mistake)

2010-07-01
19:45
If you delete a database file but not its *-wal file, then open the database (thus creating a new empty database file) the *-wal file is automatically deleted. (check-in: 95c69dfb user: drh tags: trunk)

11:06
Remove debugging code from test script. (check-in: a85ae332 user: dan tags: trunk)
10:15
Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.). (check-in: 4932f228 user: dan tags: trunk)
2010-06-26

Reduce the average (but not maximum) size of the allocations made as part of a checkpoint. (check-in: 4a7fd91b user: dan tags: trunk)
15:16
Reduce the size of the large allocation (approx 8KB for every 4000 frames in the log) that occurs during checkpoint. Use the 'scratch' memory for this allocation instead of the general purpose allocation. (check-in: 29887487 user: dan tags: trunk)
14:17

15:55
Add a version number to the wal-index header. If SQLite encounters a version number in either the wal or wal-index files that it does not understand, the operation is abandoned and SQLITE_CANTOPEN returned. (check-in: 8d0f8a7f user: dan tags: trunk)
15:18

Fix an assert() failure that could occur if compiling with OMIT_SHARED_CACHE. (check-in: 3e76a9f2 user: dan tags: experimental)
18:12
Change the name of IOCAP_SAFE_DELETE to IOCAP_UNDELETABLE_WHEN_OPEN. Have the xDeviceCharacteristics() method of the win32 VFS return this flag. (check-in: 5a5ff4e3 user: dan tags: experimental)
17:26
Add tests to pager1.test and pagerfault.test. (check-in: f5df83fd user: dan tags: experimental)
15:10
Change the unix VFS to always allocate shared-memory using a file in the same directory as the database. Otherwise, a chroot might cause different processes to use different shared memory files resulting in database corruption. (check-in: 2241788b user: drh tags: trunk)
11:30
Add tests to pager1.test and pagerfault.test. (check-in: 58c0b5bf user: dan tags: experimental)
2010-06-18
18:59
Add tests to pager1.test. (check-in: 582fca89 user: dan tags: experimental)
16:13
Rearrange some code in OP_JournalMode to avoid incorrect returns from subsequent invocations of "PRAGMA journal_mode" following an IO error. (check-in: ce0a4a9b user: dan tags: experimental)
11:10
Change the implementation of the unix implementation of xAccess() so that it returns 0 (does not exist) to an SQLITE_ACCESS_EXISTS query on a file that exists but is zero bytes in size. (check-in: 077b0e5b user: dan tags: experimental)
2010-06-17
17:05
Apply [b9b11855e8] (the alternate fix to [fc62af4523]) to the trunk. (check-in: 9a949a3a user: dan tags: trunk)
16:44
Merge trunk change [7c3a86b9c7]. (check-in: bd7bc4e0 user: dan tags: experimental)
16:44
A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. (check-in: b9b11855 user: dan tags: experimental)
16:08
Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. (check-in: 7c3a86b9 user: drh tags: trunk)
11:36
Fix bug in journal2.test. (check-in: c1e04f1d user: dan tags: experimental)
10:52
Merge trunk updates with experimental branch. Also add tests to journal2.test. (check-in: 9f6ea1de user: dan tags: experimental)
10:42
Do not delete the journal file in "PRAGMA journal_mode" commands. This fixes [fc62af4523]. (check-in: 1ec74591 user: dan tags: trunk)
10:24
Add test case for [fc62af4523]. (check-in: cccd32c6 user: dan tags: trunk)
06:19
Merge fix [f80c3f922a] with experimental changes. (check-in: 20133e9c user: dan tags: experimental)
02:13
Bug fix: Only trust the database size number at offset 28 if the change counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version. (check-in: f80c3f92 user: drh tags: trunk)
2010-06-16
19:04
Experimental change: On systems where it is not possible to unlink a file while one or more processes has it open (i.e. not unix), avoid closing the journal file each time the database is unlocked and reopening it at the start of each transaction. (check-in: bede8c8a user: dan tags: experimental)
12:30
Add extra test cases to pager1.test. (check-in: ad320957 user: dan tags: trunk)
10:55
Fix a memory leak that can occur in os_unix.c if an IO error occurs within the xUnlock method. (check-in: 6c5c04ee user: dan tags: trunk)
2010-06-15

Run extra iterations in wal3.test to ensure test coverage. (check-in: ea80cbe5 user: dan tags: trunk)
14:06
Merge in [2c5e48a485]. Merge in [2c5e48a485]. Merge in [2c5e48a485]. (check-in: 03c0f4fd user: dan tags: trunk)
13:56
Changes to the way tcl test scripts work. No changes to production code. (Closed-Leaf check-in: 2c5e48a4 user: dan tags: experimental)
12:09
Minor tweaks to the interface documentation - adding hyperlinks. (check-in: 07b2fdd1 user: drh tags: trunk)
11:21
Updates to comments and testcase() macros in wal.c. (check-in: 4d90cc0b user: drh tags: trunk)
2010-06-14
18:06
Fix an error in the walfault.test script introduced by the previous check-in. (check-in: a2b9374f user: drh tags: trunk)
18:01
Move the xShmMap method to in between xShmLock and xShmBarrier, since it seems to fit in there logically. (check-in: 58dfd83d user: drh tags: trunk)
17:09
Merge the experimental shared-memory mmap-by-chunk changes into the trunk. (check-in: f295e7ed user: drh tags: trunk)
16:16
Add the new xShmMap (formerly xShmPage) to os_win.c. (check-in: 13e7a824 user: dan tags: experimental)
14:07
Remove xShmGet/Size/Release from the sqlite3_vfs structure. Change the name of xShmPage to xShmMap. Remove some code that is now unused from os_unix.c and some of the test VFS implementations. (check-in: fc0cabc1 user: dan tags: experimental)
11:49
Update some comments in wal.c. No code changes. (check-in: 1ce9c92b user: dan tags: experimental)
11:18
Change the interface to internal function walGetHash() to make it easier to follow. (check-in: 5e8e2e97 user: dan tags: experimental)
10:30
Add the xShmPage method to the "crash" vfs in test6.c. (check-in: 1008f536 user: dan tags: experimental)
07:53
Add some fault-injection tests to improve coverage. (check-in: 37b26d12 user: dan tags: experimental)

Fix some problems with handling IO errors on the experimental branch. (check-in: eade8bc2 user: dan tags: experimental)
2010-06-11
19:04
Experimental change to the xShmXXX parts of the VFS interface. (check-in: ca68472d user: dan tags: experimental)
17:01
Refactor and simplify the logic used to change journalmode. (check-in: 95cc3f6f user: drh tags: trunk)
2010-06-10
16:25
Adding original art for the new SQLite logo. (check-in: af353bd8 user: drh tags: trunk)
14:07
Add the SQLITE_TESTCTRL_PGHDRSZ verb for sqlite3_test_control() used to get the size of pcache headers for testing purposes. (check-in: 5d694f04 user: drh tags: trunk)
10:51
Update the test VFS in test_journal.c so that it implements the xCurrentTimeInt64 method. (check-in: ec3b4a7e user: drh tags: trunk)
06:53
Store the MemPage structure in memory following, instead of preceding, the page data for cached pages. This reduces the likelihood of a corrupt database page image causing SQLite to read past the end of a buffer. (check-in: 0ce42e76 user: dan tags: trunk)
01:07
Remove a condition that must always be true. Replace it with an assert(). (check-in: 7abcd54e user: drh tags: trunk)
2010-06-09
19:01
Fix test script problems causing errors in the "inmemory_journal" permutations. (check-in: ea05b7f9 user: dan tags: trunk)
16:58
When restarting (wrapping) a log file, set all unused aReadMark[] slots to READMARK_NOT_USED instead of 0. Setting them to 0 does not cause a problem, but may cause SQLite to obtain and release a few more file locks than would otherwise be necessary. (check-in: 0797b10c user: dan tags: trunk)
15:47
Fix for ticket [f973c7ac31]. (check-in: 6eb058dd user: dan tags: trunk)
14:45
Shift the meaning of aReadMark[] back so that +1 offset from mxFrame is removed. Add the new READMARK_NOT_USED value (0xffffffff) instead of zero to signal an aReadMark[] that is not in use. (check-in: c576827d user: drh tags: trunk)
11:28
Simpler fix for the race condition also fixed by [7c102c7b5f] (check-in: 3c2de820 user: dan tags: trunk)
2010-06-08
15:50
Close database opened by tester.tcl when it is sourced in all.test. Because test scripts are now run in slave interpreters, this connection was not being closed by the first script run as it was previously. (check-in: b072e9f6 user: dan tags: trunk)
15:16
Changes to wal3.test to support small default cache size settings. And builds that create autovacuum databases by default. (check-in: ac4cc257 user: dan tags: trunk)
2010-06-07
19:26
In os_unix.c, call munmap() to unmap a shared-memory region prior to closing the associated file descriptor. (check-in: 95cc976f user: dan tags: trunk)
17:47
Change all.test, quick.test and permutations.test so that they use a separate interpreter for each test file. (check-in: 7c33eb5a user: dan tags: trunk)
14:28
Refactor some of the global variables and commands used by tester.tcl. (check-in: c2edf8e1 user: dan tags: trunk)
06:11
Add a couple of extra coverage tests for wal.c. (check-in: cfe60254 user: dan tags: trunk)
2010-06-05
19:18
Add further test cases for the logic in sqlite3WalBeginReadTransaction(). (check-in: a49713db user: dan tags: trunk)
18:34
Clarify the purpose of a test for a race-condition in sqlite3WalBeginReadTransaction(). (check-in: c041c6a9 user: dan tags: trunk)
18:12
Remove a condition from sqlite3WalRead() that is unreachable as of the changes to clear entries out of the wal-index hash tables on transaction or savepoint rollback. (check-in: 39420473 user: dan tags: trunk)
14:42
Mark a condition in wal.c as ALWAYS(). (check-in: 3fe0cc78 user: dan tags: trunk)
11:53
Add extra coverage test cases for wal.c. No changes to production code. (check-in: f9d4ae0e user: dan tags: trunk)
2010-06-04
18:38
Clarify an assert in sqlite3WalExclusiveMode(). (check-in: 25585069 user: dan tags: trunk)
17:16
Remove an unnecessary branch from wal.c. (check-in: 8e54786c user: dan tags: trunk)
15:59
Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". (check-in: ca327e32 user: dan tags: trunk)
12:22
Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. (check-in: 157feba1 user: dan tags: trunk)
11:56
If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. (check-in: b813233d user: dan tags: trunk)
10:37
Fix a problem where an SQLITE_BUSY in the checkpoint code was being treated as an IO error (abandoning, instead of just limiting, the checkpoint). (check-in: 02c4040c user: dan tags: trunk)
2010-06-03
19:10
Fix another problem in test_vfs.c. (check-in: df7d5989 user: dan tags: trunk)
18:20
Have test_vfs.c simulate IO errors in xShmLock. (check-in: fcbf7cf1 user: dan tags: trunk)
18:02
Performance fix for winShmClose(). (check-in: ed7774de user: drh tags: trunk)
16:58
Add extra tests for removing elements from wal-index hash tables as part of a rollback. (check-in: af3e598a user: dan tags: trunk)
12:35
Delay opening the sub-journal until SQLite actually needs to write data to it. (check-in: c43deb33 user: dan tags: trunk)
12:09
Remove global variables when compiled with SQLITE_OMIT_WSD (check-in: dd10a547 user: drh tags: trunk)
09:25
Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f3 user: dan tags: trunk)
09:17
If an error (OOM or SQLITE_FULL error) occurs while executing an SQL statement and a statement-transaction is automatically rolled back as a result, if a second error occurs during the statement rollback do a full transaction rollback instead. Otherwise the client can be left with an inconsistent cache. This can affect both WAL and rollback modes. (check-in: eb80ddc6 user: dan tags: trunk)
09:01
If a malloc fails while allocating a savepoint object at the pager level, do not try to roll that savepoint back later on. (check-in: 91cb08ff user: dan tags: trunk)
2010-06-02
20:38
When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpoint should fail. (check-in: c6eb0a27 user: drh tags: trunk)
18:59
Fix a problem with rolling back to a savepoint opened before the writer decided to wrap the log file. (check-in: 6b4aed6a user: dan tags: trunk)
17:15
If an error occurs while writing frames to the log to commit a transaction, do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk). (check-in: cb571c1b user: dan tags: trunk)
16:40
Added implementation of vfslog_time() for Windows testing. (check-in: b3109f85 user: shaneh tags: trunk)
16:39
Updated wal2.test for windows testing. (check-in: c3606f39 user: shaneh tags: trunk)
15:59
Make sure the directory used by os_unix.c for shared-memory files is always the same, regardless of individual client permissions and environment variable settings. (check-in: f97bd520 user: drh tags: trunk)
15:43
When walTryBeginRead() encounters an I/O error trying to set a lock (as opposed to SQLITE_BUSY) be sure to propagate that error back up the call stack. (check-in: aa2c2b67 user: drh tags: trunk)
14:45
Changes to make WAL more robust against SHM locking failures and OOM errors. (check-in: ebf40413 user: drh tags: trunk)
14:43
In the rowhash.test, make sure global variables are cleared prior to use. (check-in: 28efe0a4 user: drh tags: trunk)
12:58
Undo one of the "const" markers from the previous check-in because the value needs to be changable, even if it is not actually ever changed in the current implementation. (check-in: c24ac356 user: drh tags: trunk)
05:53
Add some 'const' markers to static data that is really constant. (check-in: e7073e23 user: dan tags: trunk)
2010-06-01
21:02
The shared-memory used by WAL on linux now really is shared memory in /dev/shm. On other unix flavors, the file is in a temporary directory rather than in the same directory as the database. (check-in: fc18c4aa user: drh tags: trunk)
19:15
Changes to the way faults are injected into xShmXXX VFS calls. (check-in: 716d99f3 user: dan tags: trunk)
17:46
Change the OOM and IO error test cases in walfault.test so that each test case runs both types of error simulation. (check-in: b627e153 user: dan tags: trunk)
15:44
Delay the decision to restart the log file until data is actually ready to be written to the log file (instead of at the start of a write transaction). (check-in: b1abfaaf user: dan tags: trunk)
15:24
The incremental checkpoint feature is not perfect yet, but it is working well enough to merge it into the trunk. (check-in: 1d3e569e user: drh tags: trunk)
14:30
Merge with [15abbc3416]. (Closed-Leaf check-in: f4b9003a user: dan tags: wal-incr-ckpt)
14:12
If an attempt to get a read-lock on the WAL fails with SQLITE_BUSY_RECOVER, call the busy-handler at the btree level. (check-in: ce644965 user: dan tags: wal-incr-ckpt)
13:17
Fix a bug introduced by the previous check-in but only seen if SQLITE_ENABLE_EXPENSIVE_ASSERTS is turned on. (check-in: 9c9ec899 user: drh tags: wal-incr-ckpt)
12:58
Fix an off-by-one boundary-value issue in walCleanupHash(). (check-in: f039552e user: drh tags: wal-incr-ckpt)
11:08
Do not hold the shared-memory mutex in os_unix.c if returning NULL. (check-in: 9622dd46 user: dan tags: wal-incr-ckpt)
10:44
If the checkpoint fails to obtain an exclusive lock on one of the read-lock bytes, do not consider this an error. (check-in: 9e95e357 user: dan tags: wal-incr-ckpt)
07:51
Fixes to the test cases in wal2.test. (check-in: cd5fbcbc user: dan tags: wal-incr-ckpt)
01:08
Comment edits and cleanup in wal.c. No functional code changes. (check-in: e8e666ab user: drh tags: wal-incr-ckpt)
00:28
Attempt to get the filectrl.test script running. (check-in: e46a8f2b user: drh tags: wal-incr-ckpt)
00:03
Fix os_unix.c so that it will compile and build on a Mac. (check-in: bc707c83 user: drh tags: wal-incr-ckpt)
2010-05-31
20:28
Fix issues with locking_mode=EXCLUSIVE in WAL. (check-in: 8deba0ce user: drh tags: wal-incr-ckpt)
18:24
Add an "isInit" field in the wal-index header that must be non-zero for a valid header. Use this to detect an uninitialized wal-index. (check-in: a16fde19 user: drh tags: wal-incr-ckpt)
16:56
Fix an inconsistent #ifdef in wal.c. Fix os_unix.c so that it does not allow moving an SHM lock directly exclusive to shared without going through unlocked. (check-in: 552658da user: drh tags: wal-incr-ckpt)
16:41
Avoid dropping the checkpoint lock after a recovery run as a precursor to a checkpoint operation. (check-in: cc25cfa0 user: dan tags: wal-incr-ckpt)
16:17
Zero the checkpoint header as the last step of successful WAL recovery. Avoid an unnecessary lock/unlock in WalBeginReadTransaction. (check-in: db3509c5 user: dan tags: wal-incr-ckpt)
16:10
Get the new xShmLock interface design working on os_win.c. (check-in: 149a7082 user: drh tags: wal-incr-ckpt)
14:39
Make sure WAL alway requests enough shared-memory space. (check-in: 138f1283 user: drh tags: wal-incr-ckpt)
14:28
Remove the tests that enable tracing based on the existance of the "vdbe_*" files when in SQLITE_DEBUG mode. (check-in: cdbb4e7c user: drh tags: wal-incr-ckpt)
14:18
Update another test case in wal.test. (check-in: 99fde69e user: dan tags: wal-incr-ckpt)
13:11
Change WAL test cases to account for the improved concurrency in the new checkpoint logic. (check-in: 2d6f2485 user: drh tags: wal-incr-ckpt)
12:30
Do not fail a checkpoint just because active readers prevent backfill. (check-in: 9aa4243e user: drh tags: wal-incr-ckpt)
12:15
Add WALTRACE() macros to help with debugging and analysis. (check-in: 765c3318 user: drh tags: wal-incr-ckpt)
12:02
Another minor fix to checkpoint on the WAL branch. (check-in: 853f1e3f user: dan tags: wal-incr-ckpt)

Fix some asserts and other things in the new WAL branch. (check-in: 181ceb32 user: dan tags: wal-incr-ckpt)
06:38
Changes to the way one of the WAL/OOM tests works. (check-in: 15abbc34 user: dan tags: trunk)
01:41
WAL runs but quickly deadlocks. (check-in: ace58acb user: drh tags: wal-incr-ckpt)
2010-05-30
19:55
Initial code for incremental checkpoint in WAL mode. This check-in compiles on unix and runs as long as you do not engage WAL mode. WAL mode crashes and burns. Consider this check-in a baseline implementation for getting the new capability up and running. (check-in: ef3ba7a1 user: drh tags: wal-incr-ckpt)
2010-05-29
08:40
Add tests to fkey2.test to check that ON CONFLICT clauses do not affect SQLite's behaviour when an FK constraint is violated. (check-in: e9e5b100 user: dan tags: trunk)
06:18
Minor changes to checksum related test cases. (check-in: 60c22bde user: dan tags: trunk)
2010-05-28
11:16
Add a test to walcksum.test to stress the checksum calculation. (check-in: 778d0c17 user: dan tags: trunk)
2010-05-26
17:31
Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. (check-in: 42705bab user: drh tags: trunk)
15:06
Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de0073 user: drh tags: trunk)
2010-05-25
15:53
Updated header comments in wal.c. No functional code changes. (check-in: 687632a6 user: drh tags: trunk)
15:23
Add a busy-handler to a test case in walthread.test to prevent errors. (check-in: d3d348aa user: dan tags: trunk)
13:49
Modify walcrash2.test so that it works with DEFAULT_AUTOVACUUM=1. (check-in: 77438882 user: dan tags: trunk)
13:40
Update header comments in wal.c to correctly describe the WAL file format. Update the locking region offsets in os_unix.c and os_win.c and add assert() statement to verify that the locking region offsets are correct. (check-in: 40030c07 user: drh tags: trunk)
10:50
If a writer exits unexpectedly in the middle of a transaction, have the following writer remove any wal-index hash-table entries left by the interrupted transaction. (check-in: ed77556a user: dan tags: trunk)
02:24
Remove unreachable code associated with WAL from the pager. (check-in: 54c1718e user: drh tags: trunk)
2010-05-24
20:27
OOM errors during an auto-checkpoint are benign. (check-in: 3d252ce5 user: drh tags: trunk)

17:00
Fix the wal2.test script so that it works in auto_vacuum mode. (check-in: 6a818afb user: drh tags: trunk)
13:57
Change the checksum used in WAL files so that each frames checksum depends on the content of the WAL header and all frame headers and content up to and including the frame to which the checksum is attached. (check-in: 8a53f12c user: dan tags: trunk)
13:28
Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4 user: drh tags: trunk)
12:34

If recovery is run before a checkpoint, change back to a CHECKPOINT lock before performing the actual checkpoint. (check-in: dc98ee16 user: dan tags: trunk)
18:04
Only pass -1 as the size parameter to xShmGet when the caller does not care what size mapping is returned. Only call xShmSize when the underlying allocation (not the mapping) should be resized. (check-in: 637f51dd user: dan tags: trunk)
17:28
Fix a bug whereby an old snapshot could be checkpointed (and subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header. (check-in: d0c0034b user: dan tags: trunk)

2010-05-05
20:00
Change the behavior of the sqlite3_wal_hook() callback. It should now return SQLITE_OK or an error code and the error code is propagated back up the stack. If a checkpoint is desired, the callback should invoke sqlite3_wal_callback() itself. (check-in: 1b14195e user: drh tags: trunk)
19:09
Further simplifications to the SHM locking logic. Remove the SQLITE_SHM_QUERY option. Unify the WRITE to READ and RECOVER to READ transitions. (check-in: e9bfa6e4 user: drh tags: trunk)

00:05
When the in single-threaded mode, the sqlite3_mutex_alloc() interface still returns a non-NULL value. The mutex doesn't do anything, but it tests non-NULL. This way, extensions (or VFSes) that use sqlite3_mutex_alloc() can tell the difference between an OOM error and mutexes being disabled. (check-in: 451fd175 user: drh tags: trunk)
2010-05-04

11:19
Fix the sqlite3_mutex_alloc() interface to return NULL (not segfault) when operating in threadsafe mode. (This is a general-purpose bug fix which really ought to be ported to trunk.) (check-in: 64840a3c user: drh tags: wal)

2010-04-12
20:54
Add e_fts3.test to the set of tests excluded from the inmemory_journal exclusion list, since it does simulated OOM errors which trigger I/O errors and SQLite is unable to recover from I/O errors without a persistent journal. (check-in: e7e7127f user: drh tags: trunk)
19:44
Recent changes cause the xSync method of the memory journal implementation to be used, so remove the assert(0). (check-in: 1f2cb940 user: drh tags: trunk)

19:36
Fix issues with the io.test script. There is still a problem with a ROLLBACK TO not working on an initially empty database files. And much more testing is needed. (check-in: 09786e2a user: drh tags: experimental)
2010-03-27
17:12
Experimental changes that cause SQLite to use bytes 28..31 of the database header to determine the database size, rather than using the actual database size. This allows database space to be preallocated. (check-in: b844ac6f user: drh tags: experimental)
09:44
Increase the estimated cost of using a virtual table as the outer loop of a join when there exists an ORDER BY clause that is not satisfied by the virtual table. Fix for [775b39dd3c]. (check-in: 9e075e70 user: dan tags: trunk)

04:32
Change the formatting of the preprocessor macros surrounding the compileoption interface in sqlite.h.in. This is so the documentation produced by parsing this part of sqlite.h.in is formatted similarly to the docs for the deprecated interfaces (with the #ifndef visible on the webpage). (check-in: 161958d1 user: dan tags: trunk)
2010-03-19

Store the SQLite version number of the last writer in bytes 96..99 of the header. (check-in: 146d4f5d user: drh tags: trunk)
16:52
Make sure the in-journal boolean vector is cleared and released when ending a transaction. This fixes an obscure problem with the previous check-in. (check-in: 69d749d9 user: drh tags: trunk)
15:48
Do not create, open, or initialize the rollback journal until something actually needs to be written into the journal. That way, expensive filesystem operations are avoided if the transaction ends up being a no-op. (check-in: b78e58ae user: drh tags: trunk)
13:59
Rewrite a couple of queries used internally by FTS3 to take advantage of the "SELECT max(x) FROM ..." optimization. (check-in: b7e42ae7 user: dan tags: trunk)

2010-03-12
16:32
Add assert()s to mem2.c (activated by SQLITE_MEMDEBUG) which verify that memory alloctions that might have come from lookaside are always freed using a lookaside-aware free routine. (check-in: c2af2164 user: drh tags: trunk)
2010-03-10
23:13
Move the ctime.c source module near the beginning of the list of files inserted into the amalgamation so that #defines that are overridden in other modules will not effect the values returned by sqlite3_compiletime_used(). (check-in: bb591802 user: drh tags: trunk)
21:42
Add the SQLITE_DBSTATUS_CACHE_SIZE verb for sqlite3_db_status(). The highwater mark does not yet work on this verb. (check-in: 418c6d81 user: drh tags: trunk)

18:46
Change a condition in sqlite3VdbeMemShallowCopy() to avoid accessing an unitialized variable (doing so was not dangerous, but caused a valgrind error). (check-in: 4793c381 user: dan tags: trunk)
17:27
Fix a one byte buffer overread in fts3. (check-in: 6e3e014a user: dan tags: trunk)
16:32
Modify the vdbe so that the comparison operator opcodes do not modify the data type of operands. Fix for [aa92c76cd4]. (check-in: 8858042f user: dan tags: trunk)
13:53
Adjustments to #ifdefs so that the #include of <sys/mount.h> is not included twice, because that confuses the amalgamation builder. (check-in: 27413fc8 user: drh tags: trunk)
13:41
Adjust some #ifdefs so that the build works on Mac both with and without SQLITE_ENABLE_LOCKING_STYLE. (check-in: 0cc981f1 user: drh tags: trunk)
2010-03-04
17:58
Fix for [9abd6aa831]. Do not overread a buffer used for an %q or %w conversion with a precision specifier. (check-in: 5e472896 user: dan tags: trunk)

Expire pragma statements when reset, even if they were not run to completion. (check-in: 78351d28 user: drh tags: trunk)
04:15
Make sure the ON clause of a LEFT JOIN does not cause an index to be used to speed access to a table to the left of the join. Ticket [ebdbadade5] (check-in: f0ae251a user: drh tags: trunk)
2010-02-24
21:44
Add testcase() macros beside each sqlite3_log() call to make sure it is tested with both logging enable and disabled. (check-in: 1168763d user: drh tags: trunk)
19:36
Changes to compile time option diags to report values for some defines. Added test cases to TCL test suite (ctime.test). (check-in: dd480f62 user: shaneh tags: trunk)
19:23
Add a sqlite3_log() call on anonymous constraint failures. Fix the output of test cases having to do with improved reprepare reporting. Fix the VACUUM command to report more helpful error messages when things go wrong. (check-in: 69a49318 user: drh tags: trunk)
18:40
Fix an incorrect ALWAYS() macro in vdbeapi.c. Fix the output of a few test cases that changed due to better error propagation out of reprepare. (check-in: a8c984c1 user: drh tags: trunk)

Fix the stmt.test test script so that it works with SQLITE_TEMP_STORE=3. (check-in: 8bf710ce user: drh tags: trunk)
20:32
Merge the compile-time option introspection interfaces into the trunk. (check-in: 9f429434 user: drh tags: trunk)
20:11
Continuing improvements to error reporting and the sqlite3_log() routine. (check-in: edea3bb7 user: drh tags: trunk)
20:08
Refactored compile time option diagnostic support to use strings identifiers instead of bitmask. (Closed-Leaf check-in: 76a0294a user: shaneh tags: compile_opts)
18:05
Fix a segfault that can occur if a malloc fails in ATTACH in shared-cache mode. (check-in: e3713737 user: dan tags: trunk)

Test new api to report which options (defines) were used to compile SQLite. (check-in: 84c97569 user: shaneh tags: compile_opts)
01:47
Add the ".log" command to the shell. This shows that some errors are logged multiple times and other errors are never logged at all. (check-in: 6d910245 user: drh tags: trunk)
01:01
Remove the ".genfkey" command from the shell. We've had foreign-key support in the core since 3.6.19. Anyone who still needs the simulated foreign-key triggers can always generate them with an older version of the shell. (check-in: c4401fc9 user: drh tags: trunk)
2010-02-22
23:17
Fix an assertion-fault/segfault problem that comes up when trying to VACUUM an auto-vacuumed database with a large schema. Ticket [da1151f97df244]. (check-in: 86d50ce5 user: drh tags: trunk)
19:37
Merge in the massive clean-up and ANSI-fication of Lemon carried out by Ryan Gordon. There are no functional changes to SQLite itself - Lemon still generates exactly the same parsing automaton from exactly the same grammar. (check-in: 1e8b8420 user: drh tags: trunk)
19:32
Log all error messages if logging is enabled. (check-in: a8076aed user: drh tags: trunk)
2010-02-19

Fixed % formatting in some printf-style strings. (check-in: f96add89 user: icculus tags: lemon-update-2010)
20:19
Corrected error message (cut-and-paste bug). (check-in: b3839f2a user: icculus tags: lemon-update-2010)
17:48
Consistent use of #ifdef for SQLITE_HAS_CODEC to avoid confusion. (check-in: 34a3413a user: shaneh tags: trunk)
05:40
Removed unused variables. (check-in: ca570a02 user: icculus tags: lemon-update-2010)
04:19
Avoid using the internal printf routine for round(x,y) in the common case where y==0. (check-in: d76ad8b3 user: shaneh tags: trunk)
03:57
More rounding tests. (check-in: 3863638b user: shaneh tags: trunk)
2010-02-16
22:06
Remove duplicated assignment in realloc. (check-in: c419955d user: shaneh tags: trunk)
22:00
Added additional rounding tests. (check-in: b8ee76bc user: shaneh tags: trunk)
16:09
Removed %expect directive, on drh's advice. (check-in: b43ac330 user: icculus tags: lemon-update-2010)
16:07
Patched to compile. Accidentally removed va_list declaration. (check-in: 673d470c user: icculus tags: lemon-update-2010)
12:18
Change a C++ style comment in os_unix.c to use normal C style commenting. (check-in: 7a193309 user: dan tags: trunk)
10:59
Fix for [e9a9fde1f4]. When opening an existing rtree, determine the node size by inspecting the root node of the r-tree structure (instead of assuming it is a function of the page-size). (check-in: ebc9433f user: dan tags: trunk)
2010-02-15
18:03
Fix the ALTER TABLE RENAME command so that it converts FOREIGN KEY constraints in ATTACH-ed and in TEMP tables as well as in the main database. Ticket [13336e9c3c8c3f]. (check-in: ab197d0a user: drh tags: trunk)
16:54
When creating a trigger on a main database table when there is a TEMP table with the same name, make sure the trigger is bound to the main table. Ticket [985771e11612]. (check-in: ec914af3 user: drh tags: trunk)
15:47
Fix a compiler warning in shell.c. Updates to comments in trigger.c. (check-in: c727601e user: drh tags: trunk)

2010-02-14
17:14
Make Lemon able to compile as C++ code. (check-in: 75a1060b user: icculus tags: lemon-update-2010)
05:42
Added option to not clip error output.

This is useful for IDEs and other tools that benefit from full path information, so they can jump directly to the error line in the source code. (check-in: 90602030 user: icculus tags: lemon-update-2010)

05:34
Delete output files if this is a failed run.

Otherwise, the fail will stop a Makefile from progressing, but if you immediately run the build again, Make will think the output files are up to date, since they are newer (albeit incomplete/incorrect). (check-in: e38c08d9 user: icculus tags: lemon-update-2010)

05:19
Added %expect directive, to consider a certain number of conflicts "correct."

This has the side effect of changing the process exit code to never overflow. (check-in: d8bab8cf user: icculus tags: lemon-update-2010)

00:48

If there is a hot-journal in the file-system, a connection with journal_mode=memory set may have to open it to effect rollback. Account for this in pager_end_transaction(). This prevents an assert from failing in the in-memory journal permutation test. (CVS 6947) (check-in: 224bc69a user: danielk1977 tags: trunk)
11:41
Do not simulate OOM conditions in the sqlite3OsXXX() calls if the underlying file is an in-memory journal file. (CVS 6946) (check-in: d4868117 user: danielk1977 tags: trunk)
10:05
When extracting values from a record to use in an UPDATEd version of that record, apply OP_RealAffinity if required. Fix for #3992. (CVS 6945) (check-in: 3616766a user: danielk1977 tags: trunk)

19:31
Remove obsolete assert and testcase macros related to ticket #2565 (CVS 6943) (check-in: f0024b31 user: drh tags: trunk)
17:42

17:39
Change an unreachable condition in PagerSharedLock to a NEVER(...). Add an assert to pager_error() to show that it is never called to put an in-memory pager to the error-state. (CVS 6941) (check-in: 1d931f77 user: danielk1977 tags: trunk)
17:33
Change a condition to a '%' operator in bitvec.c. (CVS 6940) (check-in: 10250fe5 user: drh tags: trunk)

14:18
Add a NEVER() on an always-false conditional in pager.c. Make sure the text of the master journal file is zero-terminated before trying to process it - to prevent a buffer overrun in strlen(). (CVS 6937) (check-in: cc9430e3 user: drh tags: trunk)
13:42
Remove the "proc zeroblob" implementation from incrvacuum2.test. It is no longer required as of (6906) and, as #3988 points out, unreliable. (CVS 6936) (check-in: 03153831 user: danielk1977 tags: trunk)
11:46
Add files that should have gone in with the previous checkin. (CVS 6935) (check-in: 64c7afc7 user: danielk1977 tags: trunk)
11:40
Add a complex assert() that checks a pager invariant. (CVS 6934) (check-in: 2e08ad7b user: danielk1977 tags: trunk)
04:12
Add assert() statements to more tightly constrain the state of pager.c. Remove the three pager*.test scripts since they violate the constraints asserted above by modifying the state of the system in ways that it cannot be modified in a live system. (CVS 6933) (check-in: 3b6d370e user: drh tags: trunk)
00:13
Remove two more overzealous assert() statements. (CVS 6932) (check-in: 788aa9dd user: drh tags: trunk)

00:35
Further simplifications to btree.c, especially the sqlite3BtreeKey() and sqlite3BtreeData() functions. New assert() statements added to verify that these routines are called correctly. (CVS 6917) (check-in: 96cfd079 user: drh tags: trunk)
2009-07-21
19:25

17:11
Modify various routines inside btree.c to take a pointer to the return-code as a parameter and to no-op if the return-code storage location already contains a non-zero code. (CVS 6911) (check-in: 7dcf2a78 user: drh tags: trunk)
12:33
Use an ALWAYS() on a conditional in btmutex.c that is always true. (CVS 6910) (check-in: 609022ca user: drh tags: trunk)

Add some code to sqlite3VdbeMemSetZeroBlob() so that it works (less efficiently) even when OMIT_INCRBLOB is defined. Ticket #3977. (CVS 6906) (check-in: f5f7259d user: danielk1977 tags: trunk)
11:52
When the asynchronous IO backend opens a file with the EXCLUSIVE flag set, make sure only a single file-descriptor is opened (not one for reading and one for writing). This change fixes #3978. (CVS 6905) (check-in: 630e669b user: danielk1977 tags: trunk)
08:30
Changes to test scripts so that (make test) works when OMIT_INCRBLOB is defined. (CVS 6904) (check-in: 1dd834a3 user: danielk1977 tags: trunk)

2009-07-15
18:15
Fix a potential database corruption following DROP TABLE when the pending byte page corresponds to a ptrmap page. This situation cannot happen in a real deployment - but it still needs to be fixed. (CVS 6897) (check-in: 6242db39 user: drh tags: trunk)
17:25

2009-07-13
15:52
Remove the SQLITE_CommitBusy flag. This was an attempt to block recursion on the sqlite3_commit_hook() interface. But such recursion is explicitly disallowed, so the flag is pointless. (CVS 6889) (check-in: 1c2bfc43 user: drh tags: trunk)
13:18
Change an unreachable condition in btree.c to a NEVER(). (CVS 6888) (check-in: 9f800e11 user: danielk1977 tags: trunk)

06:55
Modify the integrity-check code so that each b-tree page inspected is reinitialized while doing so, even if an initialized copy exists in the cache. This prevents an assert from failing when running integrity_check on a corrupt database. (CVS 6877) (check-in: 709576c6 user: danielk1977 tags: trunk)
05:06
Remove unreachable condition from btree.c. (CVS 6876) (check-in: 47b40fef user: danielk1977 tags: trunk)

Remove an unused branch from btree.c. (CVS 6871) (check-in: 45efb78a user: danielk1977 tags: trunk)
08:27
In btree.c, have setSharedCacheLock() assume that the b-tree is sharable instead of checking to see if it is. The caller has already performed this check. (CVS 6870) (check-in: 3190eefd user: danielk1977 tags: trunk)
05:07
Restore (btree_set_cache_size) to test3.c. This is used on unix for the tcl "crash tests". Make some functions no longer used outside of btree.c static. (CVS 6869) (check-in: 1d96ce8c user: danielk1977 tags: trunk)

15:47
Do not load the root-page of a b-tree table/index when opening a cursor. Instead, allow it to be loaded when the cursor is first used (in function moveToRoot()). Also move the root-page flags sanity checks that were a part of the OP_OpenRead/OpenWrite opcodes into the moveToRoot() function. (CVS 6856) (check-in: 06dcfe72 user: danielk1977 tags: trunk)
13:56

Fix the pager so that it remembers the name of the journal for an in-memory database as an empty string. This is important when committing a multi-database transaction that includes one or more attached memory databases. (CVS 6852) (check-in: 31a5e819 user: drh tags: trunk)
19:03
Fix the backup logic so that it detects a failure to sqlite3BtreeUpdateMeta() and reports that failure back up to the top level. (CVS 6851) (check-in: 471b92f2 user: drh tags: trunk)
18:56
Make the sqlite3BtreeMoveto function static, since it is only used from within btree.c. Remove unused function lockBtreeWithRetry from btree.c. (CVS 6850) (check-in: 30d5ec62 user: danielk1977 tags: trunk)

Remove an unused variable from the test code in test3.c. (CVS 6843) (check-in: 9e35bec9 user: drh tags: trunk)
17:09
Add a version of the Lemon parser template "lempar.c" to the src/ subfolder. This new parser template contains a couple of NEVER() macros that disable tests that are needed for general grammars but not for the specific grammar used by SQLite. SQLite builds with the modified lempar.c. (CVS 6842) (check-in: d426cc64 user: drh tags: trunk)

17:21
When a b-tree transaction is committed when there are open cursors, downgrade shared-cache write-locks to read-locks instead of relinquishing all locks. Fix for #3942. (CVS 6837) (check-in: 611e704f user: danielk1977 tags: trunk)
07:47
Cause opening a transaction on a sharable b-tree module automatically obtain a read-lock on page 1. This means there is no way for sqlite3BtreeGetMeta() to fail. (CVS 6836) (check-in: e3c055f1 user: danielk1977 tags: trunk)
05:23
Fix for compilation with OMIT_AUTOVACUUM defined. Ticket #3940. (CVS 6835) (check-in: 8f0591ae user: danielk1977 tags: trunk)

Do not ignore alias "a" in a query of the form "SELECT ... FROM (...) AS a" Fix for #3935. Also expand upon (6751) to fix some similar obscure memory leaks. (CVS 6831) (check-in: 42f9d1e5 user: danielk1977 tags: trunk)
2009-06-29
06:00
Cause incremental-blob read/write operations lock shared-cache tables in the same way as normal SQL read/writes. Add complex assert statements to make sure tehe correct shared-cache locks are held when accessing the database. Eliminate some redundant checks from btree.c. (CVS 6830) (check-in: f17ef378 user: danielk1977 tags: trunk)
2009-06-27
14:10
Version 3.6.16 (CVS 6829) (check-in: ff691a6b user: drh tags: trunk, release)
11:17
Fix an instance where sqlite3JumpHere() might be called with a negative address following an OOM fault. (CVS 6828) (check-in: 49f22e55 user: drh tags: trunk)
00:48
Fix a bug in sqlite3_realloc() - if called with a size of more than 2147483392 it returns 0 but it also releases the prior allocation. (CVS 6827) (check-in: 653df0af user: drh tags: trunk)
2009-06-26
18:35
Remove incorrect NEVER() macros from malloc.c. The allocations can be exceeded using sqlite3_malloc() and sqlite3_realloc(). (CVS 6826) (check-in: 0d345e59 user: drh tags: trunk)
16:32
Removed a few compiler warnings under MSVC. (CVS 6825) (check-in: f01a9fc3 user: shane tags: trunk)
15:14
Remove the priorNewRowid field from the sqlite3 structure. Use the last_insert_rowid as the initial value when searching for a new random rowid in the OP_NewRowid opcode. (CVS 6824) (check-in: 96729b2d user: drh tags: trunk)
14:17
Skip a couple tests requiring working 64bit int support on platforms without that support. Test code change only. (CVS 6823) (check-in: d8c8145c user: shane tags: trunk)
14:04
When sqlite3VdbeAddOp() fails due to an OOM fault, return an address of 1 rather than zero so that there appears to always be a prior instruction. This prevents a negative jump-to address computation in where.c following an OOM fault. (CVS 6822) (check-in: fe02339c user: drh tags: trunk)
12:30
Fix a test script problem in exclusive.test. (CVS 6821) (check-in: a52ef5a4 user: danielk1977 tags: trunk)
12:15
Fix the new pager.c changes so that they compile with IOTRACE defined. Fix an out-of-order variable definition in vdbeaux.c. (CVS 6820) (check-in: ac145028 user: drh tags: trunk)
10:39
Another change to test_journal.c to account for (6817). Again, only test code has changed. (CVS 6819) (check-in: 58884b6c user: danielk1977 tags: trunk)
09:01
Update test_journal.c to account for (6817). Changes to test code only. (CVS 6818) (check-in: 542ee8cc user: danielk1977 tags: trunk)
07:12
Avoid writing the 8-byte journal-header magic until the journal-header is synced. In persistent journal-mode, this prevents any old content that follows an unsynced journal-header from being interpreted as part of the rollback journal. (CVS 6817) (check-in: a5ecffcf user: danielk1977 tags: trunk)
2009-06-25
16:11
Fix a problem with a return code being ignored in insertCell(). (CVS 6816) (check-in: bb5f1c01 user: danielk1977 tags: trunk)
11:50
Get the notify2.test running again by removing an ALWAYS() that was mistakenly inserted and by taking care not to report corruption following an SQLITE_LOCKED failure during schema parsing. (CVS 6815) (check-in: 6e9140a7 user: drh tags: trunk)
09:40
Replace an "if" condition that is always true in btree.c with an assert(). (CVS 6814) (check-in: daadbd9a user: danielk1977 tags: trunk)
01:47
Improved handling of oversize string and blob errors. Other simplifications in support of full coverage testing. (CVS 6813) (check-in: 8b340766 user: drh tags: trunk)
2009-06-24
13:16
Remove an ALWAYS() macro from vdbe.c that sometimes fails on thread tests. (CVS 6812) (check-in: 52eac078 user: drh tags: trunk)
13:13
Disable the new malloc-37 test when locking_mode==exclusive. The test basically works, but sometimes reports "database is locked" instead of "out of memory" and that messes up the error reporting. (CVS 6811) (check-in: 3b8f9dec user: drh tags: trunk)
11:08
Remove a declaration of the sqlite3Assert() function that was deleted by the previous check-in. (CVS 6810) (check-in: ee20b6a2 user: drh tags: trunk)
10:26
Remove the sqlite3Assert() function. The ALWAYS() and NEVER() macros call assert() directly when compiled with SQLITE_DEBUG. (CVS 6809) (check-in: d8fc373f user: drh tags: trunk)
05:40
Simplify things by rolling the functionality of balance_shallower() into balance_nonroot(). (CVS 6808) (check-in: 11750c6a user: danielk1977 tags: trunk)
2009-06-23
20:28
Enhance autoincrement so that it works with triggers that also do autoincrement inserts, even multiple inserts into the same table. Ticket #3928 (CVS 6807) (check-in: 1330993d user: drh tags: trunk)
16:40
Remove a condition from balance_nonroot() that is always true. (CVS 6806) (check-in: c5dc80e6 user: danielk1977 tags: trunk)
15:43
Call balance_shallower() from balance_nonroot() instead of from balance(). This simplifies coverage testing a bit. (CVS 6805) (check-in: da9893e2 user: danielk1977 tags: trunk)
14:39
Update the configure script for version 3.6.16 (CVS 6804) (check-in: b614e554 user: drh tags: trunk)
14:18
Update the version number in preparation for the next release. (CVS 6803) (check-in: 207c4a02 user: drh tags: trunk)
14:15
Simplifications to vdbe.c to promote better test coverage. (CVS 6802) (check-in: 3ffc93d7 user: drh tags: trunk)
11:53
Add a test to verify that #3929 is fixed. (CVS 6801) (check-in: 16c1ae9b user: danielk1977 tags: trunk)
11:22
Fix a failing assert in btree.c. The same bug was causing a spurious SQLITE_CORRUPT return when compiled without SQLITE_DEBUG. (CVS 6800) (check-in: 47ec8749 user: danielk1977 tags: trunk)
2009-06-22
19:05
Simplifications to vdbe.c and it service routines in support of coverage testing. (CVS 6799) (check-in: 308f2e61 user: drh tags: trunk)
18:03
Remove a condition that is always true from btree.c. (CVS 6798) (check-in: 3ec8b37a user: danielk1977 tags: trunk)
12:05
Make sure sqlite3BtreeCreateTable() returns an error code if the largest rootpage field is invalid in auto_vacuum mode. Update file-format comments to describe all of the "meta" values. (CVS 6797) (check-in: bda38f5e user: drh tags: trunk)
11:10
More simplifications to vdbe.c. Remove a NEVER() from vdbe.c that is possible after all. (CVS 6796) (check-in: c8f009bd user: drh tags: trunk)
05:43
If an OOM error occurs just after obtaining a shared lock on the database file, release the lock before returning. (CVS 6795) (check-in: 971a9650 user: danielk1977 tags: trunk)
00:55
Simplifications to vdbe.c in support of coverage testing. (CVS 6794) (check-in: 16680f05 user: drh tags: trunk)
2009-06-20
18:52
When recovering from the error-state in pagerSharedLock(), do not search for a hot-journal in the file-system if the pager is configured to use an anonymous temp file as the journal. (CVS 6793) (check-in: 4b46805c user: danielk1977 tags: trunk)
11:54
If after obtaining an exclusive lock to rollback a hot-journal file it is found that the journal file has been deleted, do not return an SQLITE_BUSY error. Just downgrade the lock and continue with the current operation. This eliminates a spurious SQLITE_BUSY error caused by a race condition. (CVS 6792) (check-in: 9a066600 user: danielk1977 tags: trunk)
2009-06-19
22:50
Improved documentation on the VFS methods. Ticket #3925. (CVS 6791) (check-in: f66fc771 user: drh tags: trunk)
22:23
Do now allow a COMMIT to occur while even a single write operating is in progress. (CVS 6790) (check-in: 605520ec user: drh tags: trunk)
18:32
Fix the comment on the sqlite3PExpr() subroutine. Ticket #3924. (CVS 6789) (check-in: 4bb96db6 user: drh tags: trunk)
17:50
If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point. Previously this was only attempted if the pager was configured to use exclusive mode. (CVS 6788) (check-in: 62db08bc user: danielk1977 tags: trunk)
16:44
Make sure group_concat() ignores initial NULL values. (CVS 6787) (check-in: 90c3b23c user: drh tags: trunk)
14:06
Reorganize and cleanup the prepared statement object. Remove code that has been commented out for ages and is no longer relevant to anything. (CVS 6786) (check-in: 37ae5f5e user: drh tags: trunk)
02:25
Fix a possible segfault when backing up an encrypted database. (CVS 6785) (check-in: 7d8f178c user: drh tags: trunk)
00:33
Make sure the sqlite3VdbeGetOp() subroutine works even when SQLite is compiled with SQLITE_OMIT_TRACE. (CVS 6784) (check-in: 1c8ec2a6 user: drh tags: trunk)
2009-06-18
20:52
Changes to the backup functionality so that it works better with codecs. (CVS 6783) (check-in: 87d6796d user: drh tags: trunk)
17:22
Move codec management from database connections into the pager so that it will work together with shared cache. (CVS 6782) (check-in: ed08b53c user: drh tags: trunk)
11:34
Update the filefmt.test test script to conform to the previous check-in. (CVS 6781) (check-in: 40a40e81 user: drh tags: trunk)
11:29
Reduce the minimum usable page space to 480 byte from 500 bytes. (CVS 6780) (check-in: db4fb835 user: drh tags: trunk)
00:41
Remove the P3 operand from OP_IsNull since it was not being used. (CVS 6779) (check-in: 767ef1e4 user: drh tags: trunk)
2009-06-17
22:50
Avoid an assertion fault if an out-of-memory error occurs while trying to run the string-concatentation operator on a zero-blob. (This is an absurd thing to do, but even so, we still should not fault.) (CVS 6778) (check-in: 0def0b76 user: drh tags: trunk)
21:42
Fix a problem in vdbe.c that could cause a double-free of memory if the SQLITE_LIMIT_LENGTH is changed after a statement is prepared but before it is run. Also remove debugging statements from tkt3841.test. (CVS 6777) (check-in: 3d7327fd user: drh tags: trunk)
16:20
Use caution to avoid integer overflow when doing real to integer affinity operations. Ticket #3922. (CVS 6776) (check-in: 39255946 user: drh tags: trunk)
13:57
Fix a potential segfault following database corruption. Problem made visible by check-in (6772). (CVS 6775) (check-in: 69eb0ff8 user: drh tags: trunk)
13:09
Suppress some -Wextra compiler warnings from GCC. (CVS 6774) (check-in: 59ec937c user: drh tags: trunk)
11:49
Fix a bug affecting secure-delete mode introduced by (6768). (CVS 6773) (check-in: a433ca82 user: danielk1977 tags: trunk)
11:13
Fix for #3918. Also, fix the TRACE macros in balance_nonroot(). (CVS 6772) (check-in: 368e44ec user: danielk1977 tags: trunk)
01:17
A minor simplification to the tokenizer. (CVS 6771) (check-in: 18f2076a user: drh tags: trunk)
00:35
Changes to prepare.c and callback.c to promote better test coverage. (CVS 6770) (check-in: 08cca219 user: drh tags: trunk)
2009-06-16
17:49
Changes sqlite3_prepare_v2() (and related routines) so that if it fails due to a missing table and the schema is out of date, it retries once before returning SQLITE_SCHEMA. Other changes to prepare.c to facilitate coverage testing. (CVS 6769) (check-in: 256ec3c6 user: drh tags: trunk)
16:50
Changes to balance_nonroot() and BtreeDelete() to simplify delete operations and reduce stack/heap usage while balancing b-tree structures. (CVS 6768) (check-in: 092b276e user: danielk1977 tags: trunk)
14:15
Fix a link error and warning that can occur in where.c when compiling under MSVC with SQLITE_OMIT_VIRTUALTABLE defined. Ticket #3914. (CVS 6767) (check-in: 793c93be user: shane tags: trunk)
04:35
Leave out a redundant line in build.c. Ticket #3916. (CVS 6766) (check-in: d9f997ae user: danielk1977 tags: trunk)
04:31
Remove a duplicate assert from btree.c. Ticket #3915. (CVS 6765) (check-in: d89542cd user: danielk1977 tags: trunk)
2009-06-15
23:15
Additional updates to the symbol resolver and expression tree walker to facilitate test coverage. (CVS 6764) (check-in: a49c2d4b user: drh tags: trunk)
20:45
Changes to allow a clean compile with no floating-point instructions generated when SQLITE_OMIT_FLOATING_POINT is used. (CVS 6763) (check-in: 1591b832 user: drh tags: trunk)
18:32
Updates to resolve.c to facilitate full coverage testing. (CVS 6762) (check-in: c50f0f28 user: drh tags: trunk)
16:27
Fix compiler warnings with MSVC build. (CVS 6761) (check-in: e1e64307 user: shane tags: trunk)

Version 3.6.15 (CVS 6760) (check-in: aff34826 user: drh tags: trunk, release, version-3.6.15)
00:04
Update the configuration script for version 3.6.15. (CVS 6759) (check-in: 14df65dc user: drh tags: trunk)
2009-06-14
12:47
Detect database corruption and abort balance_nonroot() before the corruption causes problems. (CVS 6758) (check-in: 3448b39d user: drh tags: trunk)
2009-06-12
17:46
Change lemon so that it does not generate yytestcase() macros on destructor cases since destructors are commonly unreachable in a reasonable grammar. For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757) (check-in: caebfe82 user: drh tags: trunk)
15:47
The previous check-in ((6755)) put in more yytestcase() macros than are called for. This check-in addresses that problem. (CVS 6756) (check-in: a5b182f9 user: drh tags: trunk)
13:53
The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include. (CVS 6755) (check-in: fe9c9177 user: drh tags: trunk)
12:50
In lemon: omit unused entries from the end of the yyFallback array. (CVS 6754) (check-in: 9cfbe2ba user: drh tags: trunk)
12:04
Enable the SQLITE_LIMIT_FUNCTION_ARG limiter. (CVS 6753) (check-in: a17e3317 user: drh tags: trunk)
11:42
Remove a C++-ism from the code. Ticket #3912. (CVS 6752) (check-in: bc729bc3 user: drh tags: trunk)
03:47
An additional memory leak in the parser fixed. Ticket #3911. (CVS 6751) (check-in: 6197b492 user: drh tags: trunk)
03:27
Make sure nested queries with USING clauses do not leak memory. Preliminary fix for ticket #3911. (CVS 6750) (check-in: bd341a10 user: drh tags: trunk)
02:27
Modifications to the parser to eliminate unreachable code. (CVS 6749) (check-in: 457e0b24 user: drh tags: trunk)
2009-06-11
17:32
Honor the SQLITE_OPEN_READONLY flag even on a :memory: or temporary database, even though such a database is pointless. Ticket #3908. (CVS 6748) (check-in: 73ba841a user: drh tags: trunk)
17:04
Add an ALWAYS() to a conditional in where.c. (CVS 6747) (check-in: 1fdb3e1e user: drh tags: trunk)
00:47
Changes to reenable codec operation and to handle memory allocation failures within a codec. (CVS 6746) (check-in: 43a6ca98 user: drh tags: trunk)
2009-06-10
19:33
Do not let the reverse_unordered_selects pragma force the use of an index that would not otherwise be used. Ticket #3904. Also: remove an test which is always true. (CVS 6745) (check-in: 78a391dc user: drh tags: trunk)
11:07
Remove a NEVER() that can sometimes occur on an OOM error. (CVS 6744) (check-in: c27f23bb user: drh tags: trunk)
09:11
Minor tweak to balance_quick() to save a few instructions. (CVS 6743) (check-in: 9ace9959 user: danielk1977 tags: trunk)
2009-06-09
19:53
Remove the actual checks that verify that memory pools (such as set up using SQLITE_CONFIG_HEAP) are 8-byte aligned. But document that 8-byte alignment is required. (CVS 6742) (check-in: e9b55ccc user: drh tags: trunk)
18:58
Fix compiler warnings with MSVC build. (CVS 6741) (check-in: 0bd84e73 user: shane tags: trunk)
18:14
Avoid a false failure report in the test scripts caused by the vdbe stack "compression" script. (CVS 6740) (check-in: 9d332989 user: shane tags: trunk)
18:02
Require that the buffer specified by SQLITE_CONFIG_HEAP be 8-byte aligned. (CVS 6739) (check-in: 18b78068 user: drh tags: trunk)
18:01
Changes to tokenize.c to facilitate full coverage testing. (CVS 6738) (check-in: 5e8c48cf user: drh tags: trunk)
