hghave: allow adding customized features at runtime
Before this patch, there is no way to add customized features to
`hghave` without changing `hghave` and `hghave.py` themselves.
This decreases reusability of `run-tests.py` framework for third party
tools, because they may want to examine custom features at runtime
(e.g. existence of some external tools).
To allow adding customized features at runtime, this patch makes
`hghave` import `hghaveaddon` module, only when `hghaveaddon.py` file
can be found in directories below:
- `TESTDIR` for invocation via `run-tests.py`
- `.` for invocation via command line
The path to the directory where `hghaveaddon.py` should be placed is
added to `sys.path` only while importing `hghaveaddon`, because:
- `.` may not be added to `PYTHONPATH`
- adding additional path to `sys.path` may change behavior of
subsequent `import` for other features
`hghave` is terminated with exit code '2' at failure of `import
hghaveaddon`, because exit code '2' terminates `run-tests.py`
immediately.
This is a one of preparations for issue4677.

""" 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/*" """ # enable importing on demand to reduce startup time from mercurial import demandimport; demandimport.enable() from mercurial import dispatch import sys, os, shlex def main(): 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, 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 = ['-R', repo, 'serve', '--stdio'] if readonly: cmd += [ '--config', 'hooks.pretxnopen.hg-ssh=python:__main__.rejectpush', '--config', 'hooks.prepushkey.hg-ssh=python:__main__.rejectpush' ] dispatch.dispatch(dispatch.request(cmd)) 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("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()
