From Revision 5365.5.8 to 5354

Rev	Summary	Authors	Date
5365.5.8	Add tests that we handle sizes close to and >2GB properly. Add tests that we handle sizes close to and >2GB properly. We can't use %llu because that wasn't added until python 2.7, but we can use str(PyLong).	John Arbash Meinel	14 years ago
5365.5.7	Document some perf decisions. Document some perf decisions.	John Arbash Meinel	14 years ago
5365.5.6	For a single page test, we parse() still takes 47us For a single page test, we parse() still takes 47us parse().all_keys() takes 66.6us if we don't intern, and 86.9us if we do. (10us is hash() time) We'll need to think about whether interning is worthwhile. For some cases we are optimizing for, it will bloat. However, if we only do keys that we actually return, then likely we are ok, and ahead to intern. Because those keys will then get used to read chk maps, or have been read from them. So I'll leave intern() in for now.	John Arbash Meinel	14 years ago
5365.5.5	Found some more bugs. I wasn't incrementing one of the point... Found some more bugs. I wasn't incrementing one of the pointers, so I was parsing all the records, but not saving them correctly.	John Arbash Meinel	14 years ago
5365.5.4	Some direct tests of the hex and unhex functions. Some direct tests of the hex and unhex functions. As they say, untested code is broken code. And my code was broken. (I didn't actually init the array, I had bugs in my init strings, etc.)	John Arbash Meinel	14 years ago

5365.5.2	Parse times are dramatically improved. Parse times are dramatically improved. using _LeafNode directly, the total parse time is actually 369us. Putting all the items into a 'dict' ends up costing 250us by itself, and a minor overhead to put that into the _LeafNode object itself. Switching it around to call parsed(buffer...).all_items() to actually construct the items again, and we see that it costs another 120us for the _LeafNode implementation (which has to sort), while the Pyrex implementation goes from 50us to parse, to just 120us to create all the objects and return them. It doesn't have to sort, because they are stored in sorted order. all_keys() is even better at 94us vs 454us. I'm rather impressed that PyString_FromFormat is actually pretty reasonable. Certainly inefficient overall (since we'll eventually parse back into ints again), but does a good job.	John Arbash Meinel	14 years ago
5365.5.1	Implement a custom parser for chk btree leaves. Implement a custom parser for chk btree leaves. The basic parsing is actually quicker (47us to build this new structure vs 110us) Most likely because we have 1 malloc rather than N per leaf. Memory size is also much smaller. We'll lose a little bit if we convert back and forth from keys, etc.	John Arbash Meinel	14 years ago
