win32: remove useless lstat() fallback in nlinks() The fallback was introduced by 3b4f05ff3130 at the same time than nlinks(). Apparently it only handles the case where target path does not exist. Just raise IOError directly.

win32: correctly break hardlinks on network drives (issue761) win32.nlinks() was often returning 1 instead of the correct hardlinks count when reading from network drives. This made commit or push to a repository on a network share to fail breaking the hardlinks in the datastore, possibly causing integrity errors in repositories linked locally on the remote side. Here is what the MSDN says about GetFileInformationByHandle(): Depending on the underlying network features of the operating system and the type of server connected to, the GetFileInformationByHandle function may fail, return partial information, or full information for the given file. In practice, we never got the correct hardlinks count when reading from and to many combinations of Window XP, 2003, Vista and 7, via network drives or RDP shares. It always returned 1 instead. The only setup returning an accurate links count was a samba on Debian. To avoid this, Mercurial now breaks the hardlinks unconditionally when writing to a network drive.

aliases: provide more flexible ways to work with shell alias arguments This patch changes the functionality of shell aliases to add more powerful options for working with shell alias arguments. First: the alias name + arguments to a shell alias are set as an HG_ARGS environment variable, delimited by spaces. This matches the behavior of hooks. Second: any occurrences of "$@" (without quotes) are replaced with the arguments, separated by spaces. This happens *before* the alias gets to the shell. Third: any positive numeric variables ("$1", "$2", etc) are replaced with the appropriate argument, indexed from 1. "$0" is replaced with the name of the alias. Any "extra" numeric variables are replaced with an empty string. This happens *before* the alias gets to the shell. These changes allow for more flexible shell aliases: [alias] echo = !echo $@ count = !hg log -r "$@" --template='.' | wc -c | sed -e 's/ //g' qqueuemv = !mv "`hg root`/.hg/patches-$1" "`hg root`/.hg/patches-$2" In action: $ hg echo foo foo $ hg count 'branch(default)' 901 $ hg count 'branch(stable) and keyword(fixes)' 102 $ hg qqueuemv myfeature somefeature

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.
