commands: use the new API to access hidden changesets in various commands In previous patches, we have added an internal API to unhide hidden changesets. This patch makes the following command use that api in nowarn mode i.e. there will be no warning while accessing hidden changesets. cat, diff, export, files, heads, identify, log, manifest, parents, status This patch also adds test demonstarting the behaviour. .. feature:: Accessing hidden changesets Set config option 'experimental.directaccess = True' to access hidden changesets from read only commands.

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/*"
