0.23.24	Change the code so that we can pass in multiple sources to m... Change the code so that we can pass in multiple sources to match against. At the moment, we only use a single source, but that will soon change.	John Arbash Meinel	16 years ago
0.23.23	Merge the gc for pyrex 0.9.6.4 updates Merge the gc for pyrex 0.9.6.4 updates	John Arbash Meinel	16 years ago

0.23.21	Rename the extension to _pyx, since Robert prefers that form Rename the extension to _pyx, since Robert prefers that form	John Arbash Meinel	16 years ago
0.23.20	For now, use _FAST=True For now, use _FAST=True This could be a reasonable 'autopack' configuration, if DeltaIndex.extend() ends up being too difficult to implement.	John Arbash Meinel	16 years ago
0.23.19	Implement a 'FAST' mode. Implement a 'FAST' mode. If we insert a text and get a 'decent' delta, then we just keep using that delta_index until we get a bad insert. (delta > 1/2 size). In this mode 'bzr pack' drops from 2m41s => 53s. Inventory pages are barely effected in size, while Text pages go from 8.2MB => 9.6MB.	John Arbash Meinel	16 years ago
0.23.18	Add some profiling comments. Add some profiling comments.	John Arbash Meinel	16 years ago

0.23.16	Properly restore the label functionality. Properly restore the label functionality.	John Arbash Meinel	16 years ago
0.23.15	Handle when self._index is NULL, mostly because the source t... Handle when self._index is NULL, mostly because the source text was the empty strig. Start using DeltaIndex as part of the stardard compressing.	John Arbash Meinel	16 years ago
0.23.14	Implement a DeltaIndex wrapper. Implement a DeltaIndex wrapper. This splits out the create_delta_index from the create_delta code. Which should also help for profiling purposes.	John Arbash Meinel	16 years ago
0.23.13	Factor out the ability to have/not have labels. Factor out the ability to have/not have labels. It turns out that labels now cost overall 10% increase in repo size. A rather large 40% increase for inventory pages. Perhaps since label == sha1 we could get away doing something differently. Note also that repository-details doesn't take into account the indexes. The .cix index for a conversion is approx 380kB, which starts to be an important factor when you consider the total content for all chk pages is less than 1.5MB.	John Arbash Meinel	16 years ago
0.23.12	Add a 'len:' field to the data. Add a 'len:' field to the data. With this field, we can now fully populate an index from expanding the group-compress pages. There might be an issue with expanding the zlib pages, though if we switched to using gzip pages that would certainly go away. (perhaps zlib would have a 'trailing bytes', though, that would make it ok.) Checking to see how much this impacts final compressed size. Next step is to try removing all labels, and see what that final size becomes.	John Arbash Meinel	16 years ago
0.23.11	Insert a fulltext if the delta is more than half the total s... Insert a fulltext if the delta is more than half the total size. Also, gcr deltas are more pithy, they probably are approx the same after compression, but decrease the range limits since the copy instructions are effectively pre-compressed.	John Arbash Meinel	16 years ago
0.23.10	Allowing the source bytes to be longer than expected. Allowing the source bytes to be longer than expected. This makes a huge difference for extraction speed. 10s versus 45s. Versus 17s for the original groupcompress code. Also, the compiled version in _groupcompress_c seems ~ the same speed as the patch-delta.c version. At the very least, the extra memory copy overhead negates any benefit.	John Arbash Meinel	16 years ago
0.23.9	We now basically have full support for using diff-delta as t... We now basically have full support for using diff-delta as the compressor. Will still need some tuning/tweaking to see how we want to proceed.	John Arbash Meinel	16 years ago
0.23.8	Add another test text. Add another test text.	John Arbash Meinel	16 years ago
0.23.7	Add a apply_delta2 function, just in case it matters. Add a apply_delta2 function, just in case it matters.	John Arbash Meinel	16 years ago
0.23.6	Start stripping out the actual GroupCompressor Start stripping out the actual GroupCompressor in preparation for using the diff-delta code. Add some tests that we can generate and apply diff deltas. We need to start adding some exceptions, and consider moving the core of the patch-delta loop back into a pure C function, as the generated code is very messy.	John Arbash Meinel	16 years ago
0.23.5	Minor changes to get diff-delta.c and patch-delta.c to compi... Minor changes to get diff-delta.c and patch-delta.c to compile. This includes bringing in 'delta.h'	John Arbash Meinel	16 years ago
