3735.38.5	A bit of testing showed that _FAST=True was actually slower... A bit of testing showed that _FAST=True was actually slower*. Now that the delta index has gaps for growth, adding a delta source costs us very little. And seems to not affect make_delta time. And the improved deltas save time spent in zlib.

3735.38.4	Another disk format change. Another disk format change. We have pretty much settled on no-labels, at least until we implement a gc+chk index (and then we can decide whether we want a fatter index or to have more content in the group). As such, we don't need to track the size of the header in the disk bytestream anymore. I decided to stick with ascii lengths in the outer wrapper. Even large repositories have a small number of groups, so there isn't many bytes that are actually wasted at that level. And it means if you 'vim foo.pack' there are bits that can actually be interpreted.	John Arbash Meinel	15 years ago
3735.38.3	Bump the repository format strings since the data stream is ... Bump the repository format strings since the data stream is now incompatible.	John Arbash Meinel	15 years ago
3735.38.2	Make the text for key4 slightly longer, rather than include ... Make the text for key4 slightly longer, rather than include key3. We were running into the 'rebuild because not enough bytes used' check, so we just needed a few more bytes on the wire to be used.	John Arbash Meinel	15 years ago
3735.38.1	Change the delta byte stream to remove the 'source length' e... Change the delta byte stream to remove the 'source length' entry. This should generally remove ~3.5 bytes from delta records. The groupcompress tests at least pass again.	John Arbash Meinel	15 years ago
3735.36.13	max() shows up under lsprof as more expensive than creating ... max() shows up under lsprof as more expensive than creating an object. timeit also says if x < y is faster than y = max(x, y). Small win, but I'll take it.	John Arbash Meinel	15 years ago
3735.36.12	Add some direct tests for CHKInventory._entry_to_bytes Add some direct tests for CHKInventory._entry_to_bytes and _bytes_to_entry. Also, add a new function _bytes_to_utf8name_key. I wanted to just add _bytes_to_key, but it seems we have code that uses the name field to check if this is a root key that should not be transmitted. Anyway, by having this function, item_keys_introduced_by avoids a bunch of .decode() calls, as well as not building up InventoryEntry objects. Also use this when gathering text_refs in GCPacker. Hopefully, we could turn it on all the time, if it got cheap enough. And it points us in the right directory for a StreamSource that sends CHK pages.	John Arbash Meinel	15 years ago

3735.36.10	type(node) is InternalNode is supposedly better than isinsta... type(node) is InternalNode is supposedly better than isinstance(node, InternalNode)	John Arbash Meinel	15 years ago
3735.36.9	Simple fix to avoid using small.difference_update(large) Simple fix to avoid using small.difference_update(large) It seems the obvious thing to do, but Python's implementation scales poorly. small = small.difference(large) scales much better [O(small) rather than O(large)].	John Arbash Meinel	15 years ago
3735.36.8	Merge bzr.dev 4208. Merge bzr.dev 4208. This brings in some more smart-server improvements, as well as the iter_files_bytes as chunked, and multi-file and directory logging.	John Arbash Meinel	15 years ago
3735.36.7	Get rid of inline and const, to reduce warnings and errors. Get rid of inline and const, to reduce warnings and errors. It seems compilers don't like it if you pass &(unsigned char ) to (const unsigned char ), and pyrex doesn't let you define 'const unsigned char', (it doesn't like const at all), so for now, just remove it, because it doesn't hurt anything. Removing inline because MSVC doesn't understand it, and causes compile failures. It wasn't really important anyway.	John Arbash Meinel	15 years ago
3735.36.6	get inventory filtering working for CHKInventory get inventory filtering working for CHKInventory	Ian Clatworthy	15 years ago
3735.36.5	iter_interesting_nodes really is a culprit causing us to hol... iter_interesting_nodes really is a culprit causing us to hold on to a record after iterating to the next record. We should try to fix that code first.	John Arbash Meinel	15 years ago
3735.36.4	Fix the GPL and copyright statements in the pyrex files Fix the GPL and copyright statements in the pyrex files	John Arbash Meinel	15 years ago
3735.36.3	Add the new address for FSF to the new files. Add the new address for FSF to the new files.	John Arbash Meinel	15 years ago

3735.36.1	Fix InternalNode._iter_nodes to split the key filter based o... Fix InternalNode._iter_nodes to split the key filter based on matches. Update LeafNode.iteritems() to use a dict lookup when the key width is correct. Shaves a reasonable amount of time off of stuff that wants to look at large portions of the inventory.	John Arbash Meinel	15 years ago
3735.2.165	fix iter_just_entries() in CHKInventories fix iter_just_entries() in CHKInventories	Ian Clatworthy	15 years ago
3735.2.164	Fix a critical bug that caused problems with the index entri... Fix a critical bug that caused problems with the index entries. We were grabbing the 'start_point' but not using it, and we weren't resetting basis_end correctly. So we ended up recording the end of the previous record as the start of the next.	John Arbash Meinel	15 years ago
