Running a Bazaar Server
3
=======================

Bazaar does not require a specialised server because it operates over HTTP, FTP
6
5
or SFTP. There is an optional smart server that can be invoked over SSH, from
7
6
inetd, or in a dedicated mode.
12
11
We describe HTTP, FTP, SFTP and HTTP-WebDAV as "dumb" servers because they do
13
12
not offer any assistance to Bazaar. If you make a Bazaar repository available
14
13
over any of these protocols, Bazaar will allow you to read it remotely. Just
15
14
enter the URL to the branch in the Bazaar command you are running.::
17
bzr log http://bazaar-vcs.org/bzr/bzr.dev
19
Bazaar supports writing over FTP, SFTP and via a plugin over HTTP-WebDAV.
21
High-performance server
22
=======================
26
The high-performance server is currently in development. The version of Bazaar
27
that accompanies this documentation is able to use the servers underlying
28
protocol as a dumb server. This is the first stage high-performance server
29
functionality to be delivered.
16
bzr log http://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev

Bazaar 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
31
28
To maintain the highest security possible, the current
32
high-performance server provides read-only access by default. To
29
smart server provides read-only access by default. To
33
30
enable read-write access, run it with ``--allow-writes``. When using
34
the SSH access method, bzr automatically runs with with the
31
the SSH access method, bzr automatically runs with the
35
32
``--allow-writes`` option.
37
The server can be configured to run in three different ways:
34
The alternative ways of configuring a smart server are explained below.
42
Using Bazaar over SSH requires no special configuration on the server::
39
Using Bazaar over SSH requires no special configuration on the server; so long
40
as Bazaar is installed on the server you can use ``bzr+ssh`` URLs, e.g.::
42
bzr log bzr+ssh://host/path/to/branch
44
If `bzr` is not installed system-wide on the server you may need to explicitly
45
tell the local `bzr` where to find the remote `bzr`::
44
47
BZR_REMOTE_PATH=~/bin/bzr bzr log bzr+ssh://host/path/to/branch
46
49
The ``BZR_REMOTE_PATH`` environment variable adjusts how `bzr` will be
47
50
invoked on the remote system. By default, just `bzr` will be invoked,
48
which requires the `bzr` executable to be on the default search path.
51
which requires the `bzr` executable to be on the default search path. You can
52
also set this permanently per-location in ``locations.conf``.
50
The ``bzr+ssh://`` URL scheme only supports absolute paths from the
51
root of the filesystem. Future versions are expected to support ``~``
52
in the same way as ``sftp://`` URLs.
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.
57
61
This example shows how to run `bzr` with a dedicated user `bzruser`
58
62
for a shared repository in ``/srv/bzr/repo`` which has a branch at
61
65
Running a Bazaar server from inetd requires an inetd.conf entry::
63
1234 stream tcp nowait bzruser /usr/bin/bzr serve --inet --directory=/srv/bzr/repo
67
4155 stream TCP nowait bzruser /usr/bin/bzr /usr/bin/bzr serve --inet --directory=/srv/bzr/repo
65
69
When running client commands, the URL you supply is a `bzr://` URL relative to
66
70
the ``--directory`` option given in inetd.conf::
68
bzr log bzr://host:1234/branchname
72
bzr 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 ``bzr
76
serve`` will not be accessible.
73
81
This mode has the same path and URL behaviour as the inetd mode. To
74
82
run as a specific user, you should use ``su`` or login as that user.
84
This example runs bzr 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
bzr serve --directory=/srv/bzr/repo
94
bzr log bzr://host/branchname
75
96
This example runs ``bzr serve`` on `localhost` port `1234`.
79
100
bzr serve --port=localhost:1234 --directory=/srv/bzr/repo
83
bzr log bzr://host:1234/branchname
104
bzr log bzr://localhost:1234/branchname
