Changes In Branch winSyscall Excluding Merge-Ins
This is equivalent to a diff from 8f28797984 to 76dec8aa9d
2011-11-12
| ||
15:41 | Merge the windows xSyscall enhancements into trunk. (check-in: c1fab9aca1 user: drh tags: trunk) | |
03:17 | Make sure to flag benign malloc failures in the Windows VFS as such. Expand use of the DO_OS_MALLOC_TEST to cover the VFS functions that can now return an out of memory error. Support an experimental --match option to the test suite that will run only those tests matching the specified pattern. (Closed-Leaf check-in: 76dec8aa9d user: mistachkin tags: winSyscall) | |
2011-11-11
| ||
23:31 | Remove use of malloc and free from the Windows VFS. Also, prevent sqlite3BtreeOpen from assuming that sqlite3OsFullPathname cannot fail. (check-in: 8966ec1797 user: mistachkin tags: winSyscall) | |
22:08 | Work in progress to implement the 'syscall' functionality for Windows. (check-in: ed88fb0024 user: mistachkin tags: winSyscall) | |
00:27 | Make sure a corrupt index does not cause a buffer overread in sqlite3VdbeRecordCompare(). (check-in: 471cf0d8e7 user: drh tags: trunk) | |
2011-11-10
| ||
21:45 | Expand passing of a last error argument to the getLastErrorMsg function. Also, remove unused SQLITE_W32_THREADS define. (check-in: 8f28797984 user: mistachkin tags: trunk) | |
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: 32ab365715 user: mistachkin tags: trunk) | |
