2012-01-11
| ||
| 16:16 | Remove code made unreachable by the enhancement of the previous check-in. check-in: 9e31a275 user: drh tags: trunk | |
| 15:47 | Make the pager less vulnerable to problems caused by shifting sector sizes when rolling back a hot journal. check-in: 629108c8 user: drh tags: trunk | |
| 11:20 | Fix the sqlite3_quota_file() function in test_quota.c so that it adds the second nul-terminator to all file names that will be passed to a VFS xOpen method. check-in: 3013f9a6 user: dan tags: trunk | |
| 01:01 | Prevent winOpenSharedMemory from masking the real return code from its call to winOpen. Also, add asserts to check the double-zero termination of database file names. check-in: 93a65776 user: mistachkin tags: trunk | |
| 00:38 | Make sure filenames handed to the VFS by the fake_big_file test procedure are double-zero terminated. check-in: d0a86860 user: drh tags: trunk | |
|
2012-01-10
| ||
| 23:18 | Only require double-zero terminators on database filenames, not any every files supplied to the xOpen method. This backs out [2544f233f1]. Also refactor the fillInUnixFile() routine in os_unix.c to reduce the number of parameters. check-in: cb774b26 user: drh tags: trunk | |
| 17:59 | Refactor sqlite3OsFileControlNoFail() into sqlite3FileControlHint(). check-in: 722735a4 user: drh tags: trunk | |
| 17:28 | Avoid passing strings with a single nul-terminator (two are required) to the VFS xOpen() method from within the code that checks to see if a master-journal file may be safely deleted. check-in: 2544f233 user: dan tags: trunk | |
| 16:56 | Add function sqlite3OsFileControlNoFail(), which is the same as sqlite3OsFileControl() except that it does not simulate OOM errors. This saves adding calls to the BenignMalloc() functions around each of the invocations of sqliteOsFileControl() that ignore the return code. check-in: af59b182 user: dan tags: trunk | |
| 16:40 | Check the return code from sqlite3OsFileControl() in sqlite3BtreeCopyFile() and report any errors that it generates. check-in: 7f852ac6 user: drh tags: trunk | |
| 00:24 | Remove the BenignMalloc() from around the call to FCNTL_OVERWRITE. Add new ones around sqlite3OsDelete(). Fix an assert that causes problems for the nx-devkit. check-in: 38bc4236 user: drh tags: trunk | |
|
2012-01-09
| ||
| 14:57 | Cherry-pick the fix to surplus overflow files in the multiplexor, check-in [1238619756c0c] in the trunk. check-in: 2f8c62c3 user: drh tags: nx-devkit | |
| 14:19 | Cosmetic changes to lemon. No changes to core functionality nor impact on SQLite. check-in: 393fc78a user: drh tags: trunk | |
| 13:41 | Make sure the multiplexor does not create unnecessary overflow files. check-in: 12386197 user: drh tags: trunk | |
| 11:37 | Have test_multiplex.c add a second nul-terminator byte to the strings that it passes to the xOpen method of the underlying VFS, in case that VFS passes the string to sqlite3_uri_parameter() or similar. check-in: 12f5b8c9 user: dan tags: trunk | |
|
2012-01-08
| ||
| 22:18 | Fix typos in commands. Combine the ExpandBlob and expandBlob macros into one. check-in: fc9179e1 user: drh tags: trunk | |
| 12:32 | Make sure the shared-memory filename sythesized by os_win.c is double-zero terminated, so that it can be used with sqlite3_uri_parameter(). check-in: 429380f9 user: drh tags: trunk | |
| 00:54 | Fix harmless compiler warning seen with MSVC. check-in: 9612bcd6 user: mistachkin tags: trunk | |
|
2012-01-07
| ||
| 15:17 | Fix a bug in lemon in computation of which non-terminals can generate an empty string. This bug and the fix make absolutely no difference for the grammar used by SQLite, but it can make a difference when lemon is used in other grammars. check-in: ce32775b user: drh tags: trunk | |
|
2012-01-06
| ||
| 13:58 | Add missing finish_test to the end of the zerodamage.test module. Disable the zerodamage module if virtual tables are omitted from the build. check-in: d2a5685b user: drh tags: trunk | |
|
2012-01-05
| ||
| 23:32 | Combine various boolean variables in the BtShared structure into a single boolean vector. Also make performance improvement simplifications to sqlite3BtreeMovetoUnpacked(). check-in: 11949331 user: drh tags: trunk | |
| 21:19 | Make sure the name of the shared memory file has two zero-terminators in the UNIX VFS, so that sqlite3_uri_parameter() will work correctly on that name. check-in: 3d088ba5 user: drh tags: trunk | |
| 18:33 | Fix an incorrect assert() on the sqlite3FileSuffix3() function. check-in: 24db54bd user: drh tags: trunk | |
| 16:07 | Change the unix VFS so that it ignores all but the least-significant bit of the syncDir flag to xDelete. Add an assert to prove that the core only ever uses that one bit. check-in: e75fd3b2 user: drh tags: trunk | |
| 13:02 | Merge all of the latest trunk changes into the sessions branch. check-in: a9bcb432 user: drh tags: sessions | |
| 12:38 | Ensure 8-byte alignment of Index.aiRowEst elements even if the size of an Index object is not a multiple of 8 bytes. check-in: 1378f905 user: drh tags: trunk | |
| 11:43 | Remove the SQLITE_FCNTL_SYNC_OMITTED cases from the unix and windows VFSes as they are no longer needed because of check-in [fd3822f1f2]. check-in: 7cf568a1 user: drh tags: trunk | |
|
2012-01-04
| ||
| 12:57 | Fix typos and comments and make minor changes to a few function names, as suggested by readership. check-in: e9d05cbb user: drh tags: trunk | |
|
2012-01-03
| ||
| 21:54 | Pull all the latest trunk changes over into the apple-osx branch. check-in: 8a048423 user: drh tags: apple-osx | |
| 21:33 | Experimental changes to prevent buffer overreads when parsing a corrupt database file. Closed-Leaf check-in: 9e5add51 user: drh tags: no-overread | |
| 14:50 | Make sure filenames passed into sqlite3OsOpen() always have the extra zero-terminators needed by sqlite3_uri_parameter(). check-in: d73e93cf user: drh tags: trunk | |
|
2012-01-02
| ||
| 18:20 | Remove the code that attempts to find the sector size from the OS and hardcode the xSectorSize methods of the unix and windows VFSes to return SQLITE_DEFAULT_SECTOR_SIZE, which is now set to 4096 unless overridden. check-in: 03d8362c user: drh tags: trunk | |
| 18:00 | Change page quantities in pcache1.c to unsigned. check-in: da52e6e8 user: drh tags: trunk | |
| 16:38 | Remove an incorrect assert() in btree.c. check-in: c1691d99 user: drh tags: trunk | |
| 15:45 | Make sure large negative arguments to PRAGMA cache_size do not cause 32-bit signed integer overflow. Also correct a requirements mark. check-in: 17c30634 user: drh tags: trunk | |
| 14:50 | Have SQLITE_FCNTL_SYNC_OMITTED use the normal method of returning an error code. check-in: fd3822f1 user: dan tags: trunk | |
| 12:41 | Fix the build so that it works when SQLITE_ENABLE_8_3_NAMES=1. check-in: d9761f15 user: drh tags: trunk | |
|
2012-01-01
| ||
| 13:58 | Tweaks to improve testability. check-in: e3a929e4 user: drh tags: trunk | |
|
2011-12-31
| ||
| 21:51 | Fix typos in comments. No changes to code. check-in: 6827338e user: drh tags: trunk | |
| 10:18 | Add calls to the BenignMalloc() functions around the SQLITE_FCNTL_OVERWRITE call in backup.c. check-in: 3e0833db user: dan tags: trunk | |
|
2011-12-30
| ||
| 18:16 | Add calls to the BenignMalloc() functions around the SQLITE_FCNTL_SIZE_HINT call in pager.c. check-in: c17a3f5e user: dan tags: trunk | |
| 16:16 | Fix a typo in the documentation for PCACHE2. No changes to code. check-in: 46e7903a user: drh tags: trunk | |
| 16:09 | Change dbstatus.test to account for the fact that the value reported by DBSTATUS_SCHEMA_USED may be slightly lower than the actual memory used on osx check-in: 6f2010c8 user: dan tags: trunk | |
| 16:07 | Fix up requirements marks for syntax diagrams to reflect the new and improved GIF renderings. check-in: 1bb23a3b user: drh tags: trunk | |
| 15:17 | Update the text of requirements associated with sqlite3_pcache_methods2. Update requirements marks embedded in code. All of the above are comment changes only; there are no changes to code in this check-in. check-in: f945c41a user: drh tags: trunk | |
| 11:43 | Hold the database handle mutex for the duration of sqlite3_db_release_memory(). check-in: eeaf2988 user: dan tags: trunk | |
| 10:54 | Minor changes to fix compilation with SQLITE_OMIT_WAL and SQLITE_OMIT_WSD defined. check-in: 26a513a8 user: dan tags: trunk | |
| 09:00 | Change an implicit i64-to-int cast in pager.c to an explicit cast. check-in: 6a71ba9c user: dan tags: trunk | |
| 05:08 | Fix some typos in comments. No code changes. check-in: 4edc5994 user: dan tags: trunk | |
|
2011-12-23
| ||
| 20:49 | Documentation updates. No changes to code. check-in: a8a1a639 user: drh tags: trunk | |
| 13:32 | Avoid excess syncs when padding a transaction in a WAL. check-in: 1f24ae71 user: drh tags: trunk | |
| 11:07 | Fix a problem with [f9c4a7c8f4] as applied to this branch. Leaf check-in: e6a04bf9 user: dan tags: branch-3.7.6 | |
| 02:07 | Merge the POWERSAFE_OVERWRITE features and the use of statvfs() from the statvfs branch into trunk. check-in: 2370d70e user: drh tags: trunk | |
| 01:04 | Change the name ZERO_DAMAGE to the more descriptive POWERSAFE_OVERWRITE. The query parameter used to control this device characteristic is now "psow". Closed-Leaf check-in: 6191c5e4 user: drh tags: statvfs | |
| 00:25 | Merge the latest trunk changes into the statvfs branch. check-in: d5e36327 user: drh tags: statvfs | |
| 00:07 | Add interfaces sqlite3_uri_boolean() and sqlite3_uri_int64() which are wrappers around sqlite3_uri_parameter() combined with internal routines for converting strings to booleans and 64-bit integers. check-in: 83d26b9a user: drh tags: trunk | |
|
2011-12-22
| ||
| 18:44 | Backport the fixes for Coverity-discovered problems in [1c27d84216], [676acce274], and [f9c4a7c8f4] from trunk to the 3.7.6 branch. check-in: a61786e7 user: drh tags: branch-3.7.6 | |
| 17:31 | Fix minor issues with FTS and RTREE discovered by coverity. check-in: 1c27d842 user: drh tags: trunk | |
| 17:10 | Check the return code from sqlite3_initialize() called from within sqlite3_soft_heap_limit64() and return an error from sqlite3_soft_heap_limit64() if sqlite3_initialize() fails. check-in: 676acce2 user: drh tags: trunk | |
| 15:30 | Fix a problem in fts3_write.c causing stack memory to be referenced after it is out of scope. check-in: f9c4a7c8 user: dan tags: trunk | |
| 02:10 | Merge recent trunk changes into the statvfs branch. check-in: 995ec8a4 user: drh tags: statvfs | |

2011-12-21
| ||
| 23:38 | Cherry-pick the SQLITE_DIRECT_OVERFLOW_READ fix for ticket [ac0ff496b7e] of changes [c5256b59ad] and [c723e3e18a] into the nx-devkit branch. check-in: 42f31f19 user: drh tags: nx-devkit | |
| 18:04 | Fix other problems where 32-bit integer overflow may cause a problem. Two that require an improbably large sub-journal and two in test harness code. Ticket [ac0ff496b7e2] check-in: c723e3e1 user: dan tags: trunk | |
| 17:00 | Avoid 32-bit overflow when calculating the byte offset of an overflow page in SQLITE_DIRECT_OVERFLOW_READ code. Fix for [ac0ff496b7]. check-in: c5256b59 user: dan tags: trunk | |
| 14:42 | Add the ability to enable or disable SQLITE_IOCAP_ZERO_DAMAGE using a URI parameter for both unix and windows. Add a file-control to query or disable the ZERO_DAMAGE setting. Add the -uri option to the "sqlite3" TCL command in tclsqlite3.c. Allow the sqlite3_uri_parameter() interface to accept a NULL pointer for its first parameter. check-in: c83627b7 user: drh tags: statvfs | |
|
2011-12-20
| ||
| 22:18 | Remove the code that tries to detect OOO header writes on a WAL recovery. The code is made obsolete by syncing the WAL header. check-in: 7ac713a1 user: drh tags: statvfs | |
| 20:13 | Refactor the sqlite3WalFrames() routine for clarity of presentation. Do the padded transaction sync as the write pointer crosses the final sector boundary instead of at the end, for efficiency. Always sync the WAL header immediately after it is written. check-in: 92c73b42 user: drh tags: statvfs | |
| 13:13 | Assert that the isCommit parameter to sqlite3WalFrames() is zero if and only if the nTruncate parameter is zero. check-in: 979daf92 user: drh tags: trunk | |
|
2011-12-19
| ||
| 15:46 | Add test for WAL mode to unixexcl.test. check-in: 4d518bd4 user: dan tags: trunk | |
| 11:57 | Merge [21b76af6ed] into statvfs branch. check-in: e694f7b1 user: dan tags: statvfs | |
| 11:16 | Fix a couple of test cases to account for the master-journal name related change in [cf3bccc2]. check-in: 21b76af6 user: dan tags: trunk | |
| 10:07 | Modify test cases to account for the ZERO_DAMAGE change. check-in: 68684495 user: dan tags: statvfs | |
| 00:31 | Some fixes to the test suite so that it works with ZERO_DAMAGE set to true. Still lots more problems remain. check-in: 41891b23 user: drh tags: statvfs | |
|
2011-12-17
| ||
| 20:02 | For improved clarity of presentation, refactor some of the code associated with ZERO_DAMAGE and sector-size. check-in: 1dde96c9 user: drh tags: statvfs | |
| 19:49 | Add SQLITE_IOCAP_ZERO_DAMAGE and enable it for both unix and windows. Use this device characteristic to reduce the required work in journaling. A side effect is that this changes the default page exists back to 1024 even with the use of statvfs(). check-in: a0be6ea4 user: drh tags: statvfs | |
| 16:25 | Fix a bad #endif with the previous check-in on this branch. check-in: 915713ff user: drh tags: statvfs | |
| 16:09 | Add support for statvfs() in os_unix.c, for determining the sector size. This causes many TCL test failures under Linux. check-in: e0d44450 user: drh tags: statvfs | |
| 13:45 | Merge in changes that cause the first sector of the WAL file to be synced when the WAL restarts. This is a fix for the power-loss corruption problem described in ticket [ff5be73dee086] check-in: 44ca4d12 user: drh tags: trunk | |
| 08:10 | Add tests to walcrash3.test. check-in: d7688042 user: dan tags: trunk | |
| 01:31 | Make sure the Salt-1 value in the WAL file is sequentially numbered at each checkpoint, as it says it should be in the documentation. check-in: 7b63b11b user: drh tags: trunk | |
|
2011-12-16
| ||
| 21:26 | Enhance the WAL header sync so that it honors the various synchronous pragmas, settings, and device characteristics. Closed-Leaf check-in: 9799241f user: drh tags: wal-header-sync | |
| 19:34 | Proposed changes that ensure that the WAL header is written prior to the first commit mark. check-in: 91d0437c user: drh tags: wal-header-sync | |
| 17:01 | Add code for a test that was failing before the persistent-wal related changes of [09ccc4a1be]. check-in: 49d21ce5 user: dan tags: trunk | |
| 15:38 | Merge the fix for [a1fa75cbdd02] from the experimental branch. Also fix the persistent-wal mode feature of truncating the WAL on close so that it always truncates the WAL to zero bytes. check-in: 09ccc4a1 user: drh tags: trunk | |
| 15:11 | Improved logging of master-journal name conflicts. check-in: b1005ef4 user: drh tags: trunk | |
| 13:42 | Merge the nx-devkit changes into trunk. check-in: cf3bccc2 user: drh tags: trunk | |
| 13:24 | Experimental fix for [a1fa75cbdd]. Closed-Leaf check-in: 6492af76 user: dan tags: experimental | |
| 05:50 | Tweaks to the way multiplexSubOpen() works, for backwards compatibility. check-in: bb403388 user: drh tags: nx-devkit | |
| 05:09 | Fix a potential infinite loop (inserted by the previous check-in) on the multiplexWrite() method of the multiplexor. check-in: 022bf427 user: drh tags: nx-devkit | |
| 04:57 | The xTruncate method for the multiplexor now changes surplus overflow files to zero-length by default. Or if the "truncate" query parameter is used, it actually deletes the surplus overflow files. This allows VACUUM to shrink the database again. check-in: 5aefef04 user: drh tags: nx-devkit | |
| 01:30 | Call sqlite3_log() with an appropriate message if unable to find a unique master-journal filename. check-in: e9177f7d user: drh tags: nx-devkit | |
| 01:21 | A better solution to being unable to find a unique master-journal filename: just delete an existing master-journal and reuse it. check-in: 2685c2b9 user: drh tags: nx-devkit | |
| 00:33 | Make sure the antipenultimate character of master-journal filenames is a "9" in order to avoid collisions with other files in 8+3 filename mode. Also, limit the number of attempts at finding a unique master-journal filename. check-in: 34a04836 user: drh tags: nx-devkit | |
|
2011-12-15
| ||
| 17:44 | Add stdio support to the quota VFS. check-in: 322bd15f user: drh tags: trunk | |
| 17:42 | Use _commit() rather than FlushFileBuffers() as a substitute for fsync() on windows. Also cast for C++ and add support for SQLITE_FCNTL_VFSNAME. Closed-Leaf check-in: e85cfe9a user: drh tags: quota-stdio | |
| 17:00 | When deleting a file with the multiplexor VFS, also delete any overflow files that exist. check-in: 3af1feaa user: dan tags: nx-devkit | |
| 13:29 | Make sure the chunksize in test_multiplex does not cause the pending byte to fall near the end of a chunk. Adjust the chunksize upward as necessary to prevent this. check-in: e05f8a29 user: drh tags: nx-devkit | |
| 11:45 | Fix some problems with dropped error codes in multiplexOpen(). check-in: 2d50f781 user: dan tags: nx-devkit | |
| 02:22 | In the multiplexor, do not try to delete overflow files that do not exist. And assume all but the last overflow file is the size of the chunk size. check-in: a822a80d user: drh tags: nx-devkit | |
