revlog: move file writing to a separate function Moves the code that actually writes to a file to a separate function in revlog.py. This allows extensions to intercept and use the data being written to disk. For example, an extension might want to replicate these writes elsewhere. When cloning the Mercurial repo on /dev/shm with --pull, I see about a 0.3% perf change. It goes from 28.2 to 28.3 seconds.

discovery: prefer loop to double-for list comprehension in changegroupsubset The double-for form of list comprehensions gets particularly unreadable when you throw in an 'if' condition. This expands the only remaining instance of the double-for syntax in our codebase into a loop.

fileset, revset: do not use global parser object for thread safety parse() cannot be called at the same time because a parser object keeps its states. This is no problem for command-line hg client, but it would cause strange errors in multi-threaded hgweb. Creating parser object is not too expensive. original: % python -m timeit -s 'from mercurial import revset' 'revset.parse("0::tip")' 100000 loops, best of 3: 11.3 usec per loop thread-safe: % python -m timeit -s 'from mercurial import revset' 'revset.parse("0::tip")' 100000 loops, best of 3: 13.1 usec per loop
