rhg: implement checkexec to support weird filesystems
In particular, some of our repos are stored on a fileserver that simulates
POSIX permissions poorly, in such a way that prevents the removal
of execute permission.
This causes rhg show a spurious unclean status, even though python
hg reports the repo as clean.
We fix this by making rhg implement the ~same checkexec logic
that python hg does.
#!/usr/bin/env python3
#
# An example FastCGI script for use with flup, edit as necessary
# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = b"/path/to/repo/or/config"
# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
# import sys; sys.path.insert(0, "/path/to/python/lib")
# Uncomment to send python tracebacks to the browser if an error occurs:
# import cgitb; cgitb.enable()
