10 check-ins using file src/os_common.h version aa3ef569
|15:22||In os_unix.c, make a distinction between pread() and pread64(). Add a new compile-time macro USE_PREAD64 to select the latter. (CVS 3709) (check-in: 177cd929 user: drh tags: trunk)|
|15:20||Call sqlite3_free() instead of free() to release a buffer allocated by sqlite3_vmprintf() in test_async.c (test suite bug only). (CVS 3708) (check-in: b078f09b user: danielk1977 tags: trunk)|
|00:14||Refactor PLWriter to remove owned buffer. DLCollector (Document List Collector) now handles the case where PLWriter (Position List Writer) needed a local buffer. Change to using the associated DLWriter (Document List Writer) buffer, which reduces the number of memory copies needed in doclist processing, and brings PLWriter operation in line with DLWriter operation. (CVS 3707) (check-in: d04fa3a1 user: shess tags: trunk)|
Refactor PLWriter in preparation for buffered-document change.
Currently, PLWriter (Position List Writer) creates a locally-owned
DataBuffer to write into. This is necessary to support doclist
collection during tokenization, where there is no obvious buffer to
write output to, but is not necessary for the other users of PLWriter.
This change adds a DLCollector (Doc List Collector) structure to
handle the tokenization case.
Also fix a potential memory leak in writeZeroSegment(). In case of error from leafWriterStep(), the DataBuffer dl was being leaked. (CVS 3706)(check-in: 1b9918e2 user: shess tags: trunk)
|17:44||Modify the interface to the pager sub-system in preparation for performing IO in blocks based on sector-size, not database page-size. (CVS 3705) (check-in: 7dc76588 user: danielk1977 tags: trunk)|
|15:04||Add some test cases simulating crashes with various storage medium sector sizes. (CVS 3704) (check-in: c3c5f658 user: danielk1977 tags: trunk)|
|13:53||Fix some problems with test cases in shared_err.test. Also a real bug causing a segfault after an IO error in pager.c. (CVS 3703) (check-in: 9f62ef1e user: danielk1977 tags: trunk)|
|11:54||Fix a comment in btree.c (CVS 3702) (check-in: 05700c11 user: drh tags: trunk)|
|11:25||Changes to support medium sector sizes larger than the database page size. (CVS 3701) (check-in: 3a3e8eb2 user: danielk1977 tags: trunk)|
|05:54||Add new OS file method to return the sector-size of the underlying storage: sqlite3OsSectorSize() (CVS 3700) (check-in: 5752d84d user: danielk1977 tags: trunk)|
