add: add back forgotten files even when not matching exactly (BC)
I accidentally did 'hg forget .' and tried to undo the operation with
'hg add .'. I expected the files to be reported as either modified or
clean, but they were still reported as removed. It turns out that
forgotten files are only added back if they are listed explicitly, as
shown by the following two invocations. This makes it hard to recover
from the mistake of forgetting a lot of files.
$ hg forget README && hg add README && hg status -A README
C README
$ hg forget README && hg add . && hg status -A README
R README
The problem lies in cmdutil.add(). That method checks that the file
isn't already tracked before adding it, but it does so by checking the
dirstate, which does have an entry for forgotten files (state 'r'). We
should instead be checking whether the file exists in the
workingctx. The workingctx is also what we later call add() on, and
that method takes care of transforming the add() into a normallookup()
on the dirstate.
Since we're changing repo.dirstate into wctx, let's also change
repo.walk into wctx.walk for consistency (repo.walk calls wctx.walk,
so we're simply inlining the call).

""" 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.prechangegroup.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()
