add support for streaming clone.
existing clone code uses pull to get changes from remote repo. is very
slow, uses lots of memory and cpu.
new clone code has server write file data straight to client, client
writes file data straight to disk. memory and cpu used are very low,
clone is much faster over lan.
new client can still clone with pull, can still clone from older servers.
new server can still serve older clients.

""" 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)
