4679.8.10	quick patch to allow bencode to handle StaticTuple objects. quick patch to allow bencode to handle StaticTuple objects.	John Arbash Meinel	15 years ago
4679.8.9	Cast objects back to tuples for 'dump-btree' Cast objects back to tuples for 'dump-btree' This gives a nicer representation in the output.	John Arbash Meinel	15 years ago
4679.8.8	I think I know where things are going wrong, at least with t... I think I know where things are going wrong, at least with tuple concatenation. However, of the 800+ failing tests on PQM, I can't reproduce the failures here (yet)	John Arbash Meinel	15 years ago
4679.8.7	A couple more locations that should use StaticTuple A couple more locations that should use StaticTuple but we need the 'from_sequence' form first.	John Arbash Meinel	15 years ago
4679.8.6	NEWS entry about StaticTuple performance. NEWS entry about StaticTuple performance. And some small comments about btree using it.	John Arbash Meinel	15 years ago
4679.8.5	Merge bzr.dev 4736 Merge bzr.dev 4736 This includes the updates to StaticTuple, etc, to build using Pyrex 0.9.6.4	John Arbash Meinel	15 years ago
4679.8.4	Comment about compiled code quality. Comment about compiled code quality.	John Arbash Meinel	15 years ago
4679.8.3	Expose bzrlib.static_tuple.StaticTuple as a thunk Expose bzrlib.static_tuple.StaticTuple as a thunk which selects between the C or pure-python version. Note a couple of places where I would like to start using it.	John Arbash Meinel	15 years ago
4679.8.2	A bit of tweaking to _flatten_node. A bit of tweaking to _flatten_node.	John Arbash Meinel	15 years ago
4679.8.1	Merge in the 2.1-static-tuple-btree branch, and restore the ... Merge in the 2.1-static-tuple-btree branch, and restore the string intern tweaks. The tweaks basically involve not interning 'sha1:' chk strings, which we can be reasonably confident are only accessed as tuples, and thus get interned into the more efficient SimpleSet. Even further, we know that we won't be combining them into larger tuples [like we do with (file_id, revision_id)]. This saves quite a bit of space in the string interned dict, since chk keys actually make up the bulk of our keys.	John Arbash Meinel	15 years ago
4679.5.1	Interning the most common 'value' entries saves about 1-2% o... Interning the most common 'value' entries saves about 1-2% of peak memory. Namely, interning the '0' content values. Note that most values have a common prefix now, and an uncommon suffix...	John Arbash Meinel	15 years ago
4679.3.84	Remove 2 more mallocs per line by using a fixed-width Static... Remove 2 more mallocs per line by using a fixed-width StaticTuple for reflists. Note that 'ref_list' is arbitrary width (think parent pointers), so we can't pre-allocate that. I suppose we could count the occurences of the separator in the memory buffer, though. That may be more efficient...	John Arbash Meinel	15 years ago
4679.3.83	Since we changed the repr() for StaticTuple, go ahead and Since we changed the repr() for StaticTuple, go ahead and wrap it back into a pure 'tuple' object so we get the easier-to-read debug info from _dump_tree.	John Arbash Meinel	15 years ago
4679.3.82	Remove a bogus 'print' statement in the tests Remove a bogus 'print' statement in the tests	John Arbash Meinel	15 years ago
4679.3.81	Fix up _simple_set_pyx.pyx to be compatible with pyrex again... Fix up _simple_set_pyx.pyx to be compatible with pyrex again. Surprisingly not as easy as I expected, but things seem to be working. Found an actual bug in the dealloc code...	John Arbash Meinel	15 years ago
4679.3.80	import_static_tuple_c() is defined as except -1, so the impo... import_static_tuple_c() is defined as except -1, so the import code knows to propogate the exception.	John Arbash Meinel	15 years ago
4679.3.79	Change the repr to print out 'StaticTuple' Change the repr to print out 'StaticTuple'	John Arbash Meinel	15 years ago
4679.3.78	Change the pure-python version of StaticTuple Change the pure-python version of StaticTuple wrather than 'has_a(tuple)' it now 'is_a(tuple)'. Making use of inheritance to avoid wasting memory on having 2 objects.	John Arbash Meinel	15 years ago
4679.3.77	Some code cleanup passes. Some code cleanup passes.	John Arbash Meinel	15 years ago
4679.3.76	Rename StaticTupleInterner => SimpleSet. Rename StaticTupleInterner => SimpleSet. This is a bit more appropriate, because the internal data type is not specialized into StaticTuple objects only. Partially because I didn't see a specific memory/speed tradeoff to caching the hash, and that accessing said hash was siginficantly faster than just calling PyObject_Hash().	John Arbash Meinel	15 years ago
