|
2011-12-06
| ||
| 19:44 | Begin adding the data-structure explaining subsystem. All is contained within (check-in: 79ae51c5 user: drh tags: tree-explain) | |
| 13:46 | Add file tkt-3a77c9714e.test, containing tests to verify that the problem documented by ticket [3a77c9714e] has been fixed. (check-in: 162421da user: dan tags: trunk) | |
| 13:24 | Do not reuse temp registers originally allocated to a subroutine within the main body of the program logic, since if the subroutine is called while the reused temp registers are in use, their values will get clobbered. Candidate fix for ticket [3a77c9714e63330] (check-in: 092d5331 user: drh tags: trunk) | |
| 00:47 | Merge the winGetLastError fixes into trunk. (check-in: 5b03ba9d user: drh tags: trunk) | |

| 18:44 | Add stdio-like I/O interfaces to the test_quota VFS. This is a prototype change for discussion and is mostly untested. This is an alternative to adding stdio-like I/O interfaces in the core. There is no guarantee that this code will make it into the trunk. If it does get to trunk, there could be many changes to the interface first. (check-in: bd3ce723 user: drh tags: quota-stdio) | |
| 02:32 | Add a prototype implementation of stdio-like routines for accessing the VFS. This is intended as documentation. The code is untested. There is no guarantee that any of this will ever make it into trunk. Substantial revision is possible prior to reaching trunk, if it ever does.

| 18:08 | Merge the PCACHE2 changes into trunk. (check-in: 457513f2 user: drh tags: trunk) | |

| 16:23 | Remove code made obsolete by the changes to index processing that allow range search on the rowid. (check-in: a5418c7f user: drh tags: trunk) | |
| 15:41 | Fix an invalid assert() statement added by [3b58f5f066]. (check-in: 888b09dd user: dan tags: trunk) | |
| 15:27 | Where possible, take advantage of the rowid at the end of index records to optimize range constraints (<, >, <=, >=) on the rowid column. (check-in: 3b58f5f0 user: dan tags: trunk) | |

2011-11-14
| ||
| 12:34 | Further work on mmap(). Still does not work right - autovacuum tests are the first to fail. (Closed-Leaf check-in: 638a39bb user: drh tags: mmap-experimental) | |
| 03:00 | Forward port the 8-byte alignment fix from branch-3.7.9. (check-in: ebf6eb6e user: drh tags: trunk) | |
| 02:53 | Fix a 8-byte alignment problem that causes a SIGBUS on Sparc. (check-in: 54cc1198 user: drh tags: branch-3.7.9) | |
| 01:55 | Begin making experimental changes to use mmap() for reading content from a database. The code compiles, but crashes on the test suite. (check-in: 09be42d5 user: drh tags: mmap-experimental) | |
|
2011-11-13

| 21:44 | Add a version number to the sqlite3_pcache_methods2 object. Other PCACHE2 documentation improvements. (Closed-Leaf check-in: 9f839ac0 user: drh tags: experimental-pcache) | |
|
2011-11-12
| ||
| 23:10 | Attempt to modify btree.c so that it assumes that calls to sqlite3PagerWrite() will reallocate the page buffer. As there is not good way to test this assumption yet, probably a few spots were missed. (check-in: ceee03c7 user: drh tags: experimental-pcache) | |
| 16:46 | Remove a couple of incorrect assert statements so that the test suite will run with -DSQLITE_DEFAULT_CACHE_SIZE=0. (check-in: 87614b62 user: drh tags: trunk) | |
| 15:41 | Merge the windows xSyscall enhancements into trunk. (check-in: c1fab9ac user: drh tags: trunk) | |

Support an experimental --match option to the test suite that will run only those tests matching the specified pattern. (Closed-Leaf check-in: 76dec8aa user: mistachkin tags: winSyscall) | |
|
2011-11-11

|
2011-11-10

| 20:21 | In winAccess, save the Win32 last error value prior to invoking user logging callback. Also, explicitly pass the Win32 last error value to winLogError in order to keep it accurate. Fixes a problem reported on the mailing list. (check-in: 32ab3657 user: mistachkin tags: trunk) | |
| 02:39 | Follow-on to the previous check-in to prevent a division by zero if the lookahead slot size is something goofy like 6 on a 32-bit machine. (check-in: 6bda711f user: drh tags: experimental-pcache) | |
| 02:24 | Use sqlite3MallocSize() to get the actual size of the memory allocation used for lookaside cache and increase the size of the cache to use the full allocation. (check-in: 0e53ecad user: drh tags: experimental-pcache) | |

| 01:53 | For the mem1.c system malloc implementation, use the malloc_usable_size() function if the HAVE_MALLOC_USABLE_SIZE macro is defined. Update autoconf to look for that function when configuring. (check-in: 2e8ab3ce user: drh tags: experimental-pcache) | |
| 00:06 | Update the API documentation for the new pcache2 interface. Change the order of parameters on the xCreate method of pcache2. (check-in: 4da70956 user: drh tags: experimental-pcache) | |
|
2011-11-08
| ||

| 13:05 | Change the default file format from 1 to 4. This means that, unless PRAGMA legacy_file_format=ON is used first, new databases will not be readable by versions prior to 3.3.0 (2006-01-10). (check-in: a35f52b1 user: drh tags: trunk) | |

| 10:37 | Add a missing va_end() macro to fts3.c. (check-in: e6f82574 user: dan tags: trunk) | |
| 02:24 | Use mkdir() and rmdir() rather than open() and unlink() to create the lock files with the unix-dotlock VFS. The change is backwards compatible and, we are told, works better on some network filesystems. (check-in: e2f08426 user: drh tags: trunk) | |
| 00:35 | Enhance the shell so that the ".schema" command works with case insensitive LIKE patterns even with PRAGMA cache_sensitive_like=ON. (check-in: b06bf3b3 user: drh tags: trunk) | |

2011-10-27
| ||
| 15:19 | If an error occurs within sqlite3_step() on a statement prepared using sqlite3_prepare_v2(), transfer both the error code and error message to the database handle before sqlite3_step() returns (so that they are available via sqlite3_errcode() and sqlite3_errmsg(). Prior to this commit, only the error code was transfered. The error message was not available until after either sqlite3_reset() or sqlite3_finalize() had been called on the statement handle.

| 14:27 | If an error occurs while writing to the database file during a VACUUM, discard the contents of the in-memory cache. This is required as if the database is a zipvfs database, the contents of the cache may be inconsistent with respect to the database as stored on disk. (check-in: 07159e84 user: dan tags: trunk) | |

| 21:01 | Formerly, we enabled fdatasync() on linux only. But now we learn that fdatasync() is not supported on Android. So we disable fdatasync() on Linux too. It can be reenabled at compile-time for those who really need it. (check-in: 70b5b309 user: drh tags: trunk) | |
| 20:47 | Add the SQLITE_MAX_SCHEMA_RETRY compile-time option to the set of options understood by "PRAGMA compile_options;" and by the "sqlite_compileoption_used()" function. (check-in: 1b124af4 user: drh tags: trunk) | |
