=======================
Running a Bazaar Server
=======================
Bazaar does not require a specialised server because it operates over HTTP, FTP
or SFTP. There is an optional smart server that can be invoked over SSH, from
inetd, or in a dedicated mode.
Dumb servers
============
We describe HTTP, FTP, SFTP and HTTP-WebDAV as "dumb" servers because they do
not offer any assistance to Bazaar. If you make a Bazaar repository available
over any of these protocols, Bazaar will allow you to read it remotely. Just
enter the URL to the branch in the Bazaar command you are running.::
bzr log http://bazaar-vcs.org/bzr/bzr.dev
Bazaar supports writing over FTP, SFTP and (via a plugin) over HTTP-WebDAV.
High-performance server
=======================
The high-performance server is currently in development. It provides a dumb
server facility as well as additional capabilities which allow the version of
bzr that accompanies this documentation to perform some operations much faster
than via dumb servers. In future releases of bzr the range of operations that
are improved by using the high-performance server will increase.
To maintain the highest security possible, the current
high-performance server provides read-only access by default. To
enable read-write access, run it with ``--allow-writes``. When using
the SSH access method, bzr automatically runs with with the
``--allow-writes`` option.
The server can be configured to run in three different ways:
SSH
---
Using Bazaar over SSH requires no special configuration on the server::
BZR_REMOTE_PATH=~/bin/bzr bzr log bzr+ssh://host/path/to/branch
The ``BZR_REMOTE_PATH`` environment variable adjusts how `bzr` will be
invoked on the remote system. By default, just `bzr` will be invoked,
which requires the `bzr` executable to be on the default search path.
The ``bzr+ssh://`` URL scheme only supports absolute paths from the
root of the filesystem. Future versions are expected to support ``~``
in the same way as ``sftp://`` URLs
(https://bugs.launchpad.net/bzr/+bug/109143).
inetd
-----
This example shows how to run `bzr` with a dedicated user `bzruser`
for a shared repository in ``/srv/bzr/repo`` which has a branch at
``/srv/bzr/repo/branchname``.
Running a Bazaar server from inetd requires an inetd.conf entry::
4155 stream tcp nowait bzruser /usr/bin/bzr /usr/bin/bzr serve --inet --directory=/srv/bzr/repo
When running client commands, the URL you supply is a `bzr://` URL relative to
the ``--directory`` option given in inetd.conf::
bzr log bzr://host/branchname
Dedicated
---------
This mode has the same path and URL behaviour as the inetd mode. To
run as a specific user, you should use ``su`` or login as that user.
This example runs bzr on its official port number of `4155` and listens on all
interfaces. This allows connections from anywhere in the world that can reach
your machine on port `4155`.
server::
bzr serve --directory=/srv/bzr/repo
client::
bzr log bzr://host/branchname
This example runs ``bzr serve`` on `localhost` port `1234`.
server::
bzr serve --port=localhost:1234 --directory=/srv/bzr/repo
client::
bzr log bzr://localhost:1234/branchname
