Summary: D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`. That has nasty problems if both `import mercurial` and `import edenscm.mercurial` are used, because Python would think `mercurial.foo` and `edenscm.mercurial.foo` are different modules so code like `try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)` would fail to handle the `edenscm.mercurial` version. There are also some module-level states (ex. `extensions._extensions`) that would cause trouble if they have multiple versions in a single process. Change imports to use the `edenscm` so ideally the `mercurial` is no longer imported at all. Add checks in extensions.py to catch unexpected extensions importing modules from the old (wrong) locations when running tests.

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/*"
