Rev	Summary	Authors	Date
0.23.52	Use the max_delta flag. Use the max_delta flag. Prefer to extract and compress bytes rather than chunks/lines. This has a fairly positive impact on the 'bzr pack' times. We still do a ''.join([bytes]), but we know that doesn't have to do any memory copying.	John Arbash Meinel	15 years ago
0.23.51	Remove the debug printing. Remove the debug printing.	John Arbash Meinel	15 years ago
0.23.50	Change the code to do the copies in bigger chunks. Change the code to do the copies in bigger chunks. We should be able to get a small number of memcopies, rather than having to copy each record individualy, or copy each hash range individually.	John Arbash Meinel	15 years ago
0.23.49	When adding new entries to the delta index, use memcpy When adding new entries to the delta index, use memcpy rather than copying them one by one.	John Arbash Meinel	15 years ago
0.23.48	Remove bogus line. Remove bogus line.	John Arbash Meinel	15 years ago
0.23.47	Use the new add_delta_source. Use the new add_delta_source. It shaves off a small amount of time, and improves the compression slightly. Next step is to work on optimizing the code. It feels like the include_entries_from_index is wasting a lot of time double copying all of the previous matches.	John Arbash Meinel	15 years ago
0.23.46	Fix a bug in create_delta_index_from_delta when inserting in... Fix a bug in create_delta_index_from_delta when inserting into a already filled hash location.	John Arbash Meinel	15 years ago
0.23.45	Add a function that updates the index for delta bytes. Add a function that updates the index for delta bytes. This avoids indexing control bytes, and helps to align the actual index pointers to the real data.	John Arbash Meinel	15 years ago
0.23.44	Remove the multi-index handling now that we have index combi... Remove the multi-index handling now that we have index combining instead.	John Arbash Meinel	15 years ago
0.23.43	Change the internals to allow delta indexes to be expanded w... Change the internals to allow delta indexes to be expanded with new source data. Now when adding a new source, the old index entries are included in the new structure. This generally seems to be better than having multiple indexes, as it improves the efficiency of the internal hash map, and avoids extra iterating. Bring back the _FAST flag. At the moment, with _FAST=True, doing bzr pack is about 37s rather than 1min, and gives 9.7MB texts, rather than 8.2MB or so. So at the moment, it is still a useful flag to have.	John Arbash Meinel	15 years ago
0.23.42	Change the code around again. Change the code around again. This time, the information about sources is maintained in the DeltaIndex object. And we pass that info down into create_delta_index, et al. Next step is to actually combine the delta indexes.	John Arbash Meinel	15 years ago
0.23.41	Start moving the information about source buffers into the a... Start moving the information about source buffers into the actual index_entry. This leads the way for combining indexes for multiple sources together.	John Arbash Meinel	15 years ago
0.23.40	Add a comment why we aren't using the list type for _sources Add a comment why we aren't using the list type for _sources	John Arbash Meinel	15 years ago
0.23.39	Merge the setup.py changes so that it actually fails if an e... Merge the setup.py changes so that it actually fails if an extension fails to build.	John Arbash Meinel	15 years ago
0.23.38	fix the local offset problem in a slightly different way. fix the local offset problem in a slightly different way. Leave moff in local offsets until encoding, and then convert. This allows us to skip the extra local variable, and just looks a bit cleaner, IMO.	John Arbash Meinel	15 years ago
0.23.37	If you are going to join the bytes anyway, use sha_string in... If you are going to join the bytes anyway, use sha_string instead of sha_strings.	John Arbash Meinel	15 years ago
0.23.36	Track down a memory leak in the refactored diff-delta.c code... Track down a memory leak in the refactored diff-delta.c code. We weren't deallocating the unpacked hash array in all code paths.	John Arbash Meinel	15 years ago
0.23.35	Add a rich-root compatible gcr+chk255+rich-root format. Add a rich-root compatible gcr+chk255+rich-root format.	John Arbash Meinel	15 years ago
0.23.34	Update groupcompress to allow it to read older conversions. Update groupcompress to allow it to read older conversions. This will be removed, but I needed it for testing.	John Arbash Meinel	15 years ago
0.23.33	Fix a bug when handling multiple large-range copies. Fix a bug when handling multiple large-range copies. We were adjusting moff multiple times, without adjusting it back.	John Arbash Meinel	15 years ago
