Remove atomicfile class.
The interface provided by opener(atomic=True) is inherently unsafe:
if an exception is raised in the code using the atomic file, the
possibly incomplete file will be renamed to its final destination,
defeating the whole purpose of atomic files.
To get around this, we would either need some bad hacks involving
sys.exc_info (to make sure things work in except: blocks), or an
interface to say "file is complete; rename it".
This is the exact interface provided by atomictempfile. Since there
are no remaining users of the atomicfile class, just remove 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 to 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}" """ from mercurial import commands import sys, os cwd = os.getcwd() allowed_paths = [os.path.normpath(os.path.join(cwd, os.path.expanduser(path))) for path in sys.argv[1:]] orig_cmd = os.getenv('SSH_ORIGINAL_COMMAND', '?') if orig_cmd.startswith('hg -R ') and orig_cmd.endswith(' serve --stdio'): path = orig_cmd[6:-14] repo = os.path.normpath(os.path.join(cwd, os.path.expanduser(path))) if repo in allowed_paths: commands.dispatch(['-R', repo, 'serve', '--stdio']) else: sys.stderr.write("Illegal repository %r\n" % repo) sys.exit(-1) else: sys.stderr.write("Illegal command %r\n" % orig_cmd) sys.exit(-1)
