| 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: 177cd92910 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: b078f09bff 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: d04fa3a13a 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: 1b9918e207 user: shess tags: trunk) | |

| 10:28 | Add crash2.test, for robustness testing with variable disk block size. (CVS 3696) (check-in: b0f8203dbb user: danielk1977 tags: trunk) | |

| 18:30 | Out-of-memory cleanup in tokenizers. Handle NULL return from malloc/calloc/realloc appropriately, and use sizeof(var) instead of sizeof(type) to make certain that we don't get a mismatch between them as the code rots. (CVS 3693) (check-in: fbc53da8c6 user: shess tags: trunk) | |
