Breezy does not require a specialised server because it operates over HTTP, FTP
5
or SFTP. There is an optional smart server that can be invoked over SSH, from
6
inetd, or in a dedicated mode.
11
We describe HTTP, FTP, SFTP and HTTP-WebDAV as "dumb" servers because they do
12
not offer any assistance to Breezy. If you make a Breezy repository available
13
over any of these protocols, Breezy will allow you to read it remotely. Just
14
enter the URL to the branch in the Breezy command you are running.::
16
brz log http://bazaar.launchpad.net/~brz-pqm/brz/brz.dev
18
Breezy supports writing over FTP, SFTP and (via a plugin) over HTTP-WebDAV.

High-performance smart server
21
-----------------------------
23
The high-performance smart server (hpss) performs certain operations much faster
24
than dumb servers are capable of. In future releases, the range of operations
25
that are improved by using the smart server will increase as we continue to
28
To maintain the highest security possible, the current
29
smart server provides read-only access by default. To
30
enable read-write access, run it with ``--allow-writes``. When using
31
the SSH access method, brz automatically runs with the
32
``--allow-writes`` option.
34
The alternative ways of configuring a smart server are explained below.
39
Using Breezy over SSH requires no special configuration on the server; so long
40
as Breezy is installed on the server you can use ``bzr+ssh`` URLs, e.g.::
42
brz log bzr+ssh://host/path/to/branch
44
If `brz` is not installed system-wide on the server you may need to explicitly
45
tell the local `brz` where to find the remote `brz`::
47
BZR_REMOTE_PATH=~/bin/brz brz log bzr+ssh://host/path/to/branch
49
The ``BZR_REMOTE_PATH`` environment variable adjusts how `brz` will be
50
invoked on the remote system. By default, just `brz` will be invoked,
51
which requires the `brz` executable to be on the default search path. You can
52
also set this permanently per-location in ``locations.conf``.
54
Like SFTP, paths starting with ``~`` are relative to your home directory, e.g.
55
``bzr+ssh://example.com/~/code/proj``. Additionally, paths starting with
56
``~user`` will be relative to that user's home directory.
61
This example shows how to run `brz` with a dedicated user `brzuser`
62
for a shared repository in ``/srv/brz/repo`` which has a branch at
63
``/srv/brz/repo/branchname``.
65
Running a Breezy server from inetd requires an inetd.conf entry::
67
4155 stream TCP nowait brzuser /usr/bin/brz /usr/bin/brz serve --inet --directory=/srv/brz/repo
69
When running client commands, the URL you supply is a `bzr://` URL relative to
70
the ``--directory`` option given in inetd.conf::
72
brz log bzr://host/branchname
74
If possible, paths starting with ``~`` and ``~user`` will be expanded as for
75
``bzr+ssh``. Home directories outside the ``--directory`` specified to ``brz
76
serve`` will not be accessible.
81
This mode has the same path and URL behaviour as the inetd mode. To
82
run as a specific user, you should use ``su`` or login as that user.
84
This example runs brz on its official port number of `4155` and listens on all
85
interfaces. This allows connections from anywhere in the world that can reach
86
your machine on port `4155`.
90
brz serve --directory=/srv/brz/repo
94
brz log bzr://host/branchname
96
This example runs ``brz serve`` on `localhost` port `1234`.
100
brz serve --listen=localhost --port=1234 --directory=/srv/brz/repo
104
brz log bzr://localhost:1234/branchname
