util: add an interpolate() function to for replacing multiple values
util.interpolate can be used to replace multiple items in a string all at once
(and optionally apply a function to the replacement), without worrying about
recursing:
>>> import util
>>> s = '$foo, $spam'
>>> util.interpolate(r'\$', { 'foo': 'bar', 'spam': 'eggs' }, s)
'bar, eggs'
>>> util.interpolate(r'\$', { 'foo': 'spam', 'spam': 'foo' }, s)
'spam, foo'
>>> util.interpolate(r'\$', { 'foo': 'spam', 'spam': 'foo' }, s, lambda s: s.upper())
'SPAM, FOO'
The patch also changes filemerge.py to use this new function.

#!/bin/sh # # revlog.parseindex must be able to parse the index file even if # an index entry is split between two 64k blocks. The ideal test # would be to create an index file with inline data where # 64k < size < 64k + 64 (64k is the size of the read buffer, 64 is # the size of an index entry) and with an index entry starting right # before the 64k block boundary, and try to read it. # # We approximate that by reducing the read buffer to 1 byte. # hg init a cd a echo abc > foo hg add foo hg commit -m 'add foo' -d '1000000 0' echo >> foo hg commit -m 'change foo' -d '1000001 0' hg log -r 0: cat >> test.py << EOF from mercurial import changelog, util from mercurial.node import * class singlebyteread(object): def __init__(self, real): self.real = real def read(self, size=-1): if size == 65536: size = 1 return self.real.read(size) def __getattr__(self, key): return getattr(self.real, key) def opener(*args): o = util.opener(*args) def wrapper(*a): f = o(*a) return singlebyteread(f) return wrapper cl = changelog.changelog(opener('.hg/store')) print len(cl), 'revisions:' for r in cl: print short(cl.node(r)) EOF python test.py
