Tune a bit the extdiff toplevel comments/samples.
* Capitalize the first letter of all sentences
* Add an example for GNU diff(1) 'context diff' mode.
* Explain the requirement for separate cmd.xxx and opts.xxx
options in .hgrc, which hopefully will guard against users
trying to add:
[extdiff]
# Add a new Mercurial command called `cdiff', which calls
# GNU diff(1) in 'context diff' mode.
cmd.cdiff = diff -Nprc5
which fails for recent crew builds with:
$ hg cdiff .
making snapshot of 1 files from rev 07dc4a569f4e
making snapshot of 1 files from working dir
diff -Nprc5: not found
The correct way to do this is by separating the cmd.cdiff and
opts.cdiff parts like this:
[extdiff]
# Add a new Mercurial command called `cdiff', which calls
# GNU diff(1) in 'context diff' mode.
cmd.cdiff = diff
opts.cdiff = -Nprc5
so add it as a new example and explicitly describe it in the
extdiff comments.

#!/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')) print cl.count(), 'revisions:' for r in xrange(cl.count()): print short(cl.node(r)) EOF python test.py
