subrepo: fix a crash when archiving an svn or git subrepo
Only hgsubrepos have a repository attribute. This is pretty hacky, but probably
the best we can do on stable. Pushing the lfstatus check down into the wrapper
for hgsubrepo (and dropping the check for lfstatus at the top of
`hgsubrepoarchive()`) resulted in various test failures because:
1) hgsubrepoarchive isn't returning the number of files archived at the
bottom, resulting in an error about += NoneType
2) These copypasta archive wrappers don't use progress bars
3) Largefiles are *not* currently archived when using extdiff (68822b7cdd01),
but pushing this context manager down into the subrepo resulted in it
apparently doing so (as evidenced by progress bars being dropped)
The other uses of `lfstatus()` are not in the substate processing loop, so they
shouldn't be an issue.
I initially put testcases in this test for largefiles-{on,off}, and it flagged
a bunch of exit code differences for `cat` and `diff`, so I backed that off.

""" 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()
