remove: avoid a bogus warning about no tracked files when removing '.' Previously, any files relative to the root of the repo that match the -I patterns would be deleted, but the command exited with 1 after printing a warning: $ hg remove -S -I 're:.*.txt' . removing sub1/sub2/folder/test.txt removing sub1/sub2/test.txt not removing .: no tracked files

remove: support remove with explicit paths in subrepos

remove: recurse into subrepositories with --subrepos/-S flag Like 'forget', git and svn subrepos are currently not supported. Unfortunately the name 'remove' is already used in the subrepo classes, so we break the convention of naming the subrepo function after the command.

cmdserver: protect pipe server streams against corruption caused by direct io Because pipe-mode server uses stdio as IPC channel, other modules should not touch stdio directly and use ui instead. However, this strategy is brittle because several Python functions read and write stdio implicitly. print 'hello' # should use ui.write() # => ch = 'h', size = 1701604463 'ello', data = '\n' This patch adds protection for such mistakes. Both stdio files and low-level file descriptors are redirected to /dev/null while command server uses them.

cmdserver: postpone creation of pipe server until run() This makes it easy to swap file descriptors while running command server.

cmdserver: use given streams as pipe channels like other commands Because commandserver itself is an hg subcommand, it shouldn't use stdio directly in principle.
