changelog: move branchinfo to changelogrevision
The function parses the extra dictionary after looking up the
changelogrevision. To avoid duplicated look up, it is better to provide
it as property of changelogrevision instead. Keep the function for a
release cycle as at least the topic extension depends on it.

""" hg-ssh - a wrapper for ssh access to a limited set of mercurial repos To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8): command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ... (probably together with these other useful options: no-port-forwarding,no-X11-forwarding,no-agent-forwarding) This allows pull/push over ssh from/to the repositories given as arguments. If all your repositories are subdirectories of a common directory, you can allow shorter paths with: command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2" You can use pattern matching of your normal shell, e.g.: command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}" You can also add a --read-only flag to allow read-only access to a key, e.g.: command="hg-ssh --read-only repos/*" """ from __future__ import absolute_import import os import shlex import sys # enable importing on demand to reduce startup time import hgdemandimport hgdemandimport.enable() from mercurial import ( dispatch, pycompat, ui as uimod, ) def main(): # Prevent insertion/deletion of CRs dispatch.initstdio() cwd = os.getcwd() readonly = False args = sys.argv[1:] while len(args): if args[0] == '--read-only': readonly = True args.pop(0) else: break allowed_paths = [ os.path.normpath(os.path.join(cwd, os.path.expanduser(path))) for path in args ] orig_cmd = os.getenv('SSH_ORIGINAL_COMMAND', '?') try: cmdargv = shlex.split(orig_cmd) except ValueError as e: sys.stderr.write('Illegal command "%s": %s\n' % (orig_cmd, e)) sys.exit(255) if cmdargv[:2] == ['hg', '-R'] and cmdargv[3:] == ['serve', '--stdio']: path = cmdargv[2] repo = os.path.normpath(os.path.join(cwd, os.path.expanduser(path))) if repo in allowed_paths: cmd = [b'-R', pycompat.fsencode(repo), b'serve', b'--stdio'] req = dispatch.request(cmd) if readonly: if not req.ui: req.ui = uimod.ui.load() req.ui.setconfig( b'hooks', b'pretxnopen.hg-ssh', b'python:__main__.rejectpush', b'hg-ssh', ) req.ui.setconfig( b'hooks', b'prepushkey.hg-ssh', b'python:__main__.rejectpush', b'hg-ssh', ) dispatch.dispatch(req) else: sys.stderr.write('Illegal repository "%s"\n' % repo) sys.exit(255) else: sys.stderr.write('Illegal command "%s"\n' % orig_cmd) sys.exit(255) def rejectpush(ui, **kwargs): ui.warn((b"Permission denied\n")) # mercurial hooks use unix process conventions for hook return values # so a truthy return means failure return True if __name__ == '__main__': main()
