If you are looking to run Bugzilla, you should see
https://github.com/bugzilla/bugzilla.
If you want to contribute to BMO, you can fork this repo and get a local copy
of BMO running in a few minutes using Vagrant.
Using Vagrant (For Development)
===============================
You will need to install the following software:
* Vagrant 1.9.1 or later
Doing this on OSX can be accomplished with homebrew:
.. code-block:: bash
brew install vagrant
For Ubuntu 16.04, download the vagrant .dpkg directly from
https://vagrantup.com. The one that ships with Ubuntu is too old.
Setup Vagrant VMs
-----------------
From your BMO checkout run the following command:
.. code-block:: bash
vagrant up
Depending on the speed of your computer and your Internet connection, this
will take from a few minutes to much longer.
If this fails, please file a bug `using this link <https://bugzilla.mozilla.org/enter_bug.cgi?assigned_to=nobody%40mozilla.org&bug_file_loc=http%3A%2F%2F&bug_ignored=0&bug_severity=normal&bug_status=NEW&cf_fx_iteration=---&cf_fx_points=---&component=Developer%20Box&contenttypemethod=autodetect&contenttypeselection=text%2Fplain&defined_groups=1&flag_type-254=X&flag_type-4=X&flag_type-607=X&flag_type-791=X&flag_type-800=X&flag_type-803=X&form_name=enter_bug&maketemplate=Remember%20values%20as%20bookmarkable%20template&op_sys=Unspecified&priority=--&product=bugzilla.mozilla.org&rep_platform=Unspecified&target_milestone=---&version=Production>`__.
Otherwise, you should have a working BMO developer machine!
To test it, you'll want to add an entry to /etc/hosts for bmo-web.vm pointing
to 192.168.3.43.
After that, you should be able to visit http://bmo-web.vm/ from your browser.
You can login as vagrant@bmo-web.vm with the password "vagrant01!" (without
quotes).
Making Changes and Seeing them
------------------------------
After editing files in the bmo directory, you will need to run
.. code-block:: bash
vagrant rsync && vagrant provision --provision-with update
to see the changes applied to your vagrant VM. If the above command fails
or db is changed, do a full provision:
.. code-block:: bash
vagrant rsync && vagrant provision
Technical Details
-----------------
This Vagrant environment is a very complete but scaled-down version of
production BMO. It uses roughly the same RPMs (from CentOS 6, versus RHEL 6
in production) and the same perl dependencies (via
https://github.com/mozilla-bteam/carton-bundles).
It includes a couple example products, some fake users, and some of BMO's
real groups. Email is disabled for all users; however, it is safe to enable
email as the box is configured to send all email to the 'vagrant' user on the
web vm.
Most of the cron jobs and the jobqueue daemon are running. It is also
configured to use memcached.
The push connector is not currently configured, nor is the Pulse publisher.
Perl Shell (re.pl, repl)
------------------------
Installed on the vagrant vm is also a program called re.pl.
re.pl an interactive perl shell (somtimes called a REPL (short for Read-Eval-Print-Loop)).
It loads Bugzilla.pm and you can call Bugzilla internal API methods from it, an example session is reproduced below:
.. code-block:: plain
re.pl
$ my $product = Bugzilla::Product->new({name => "Firefox"});
Took 0.0262260437011719 seconds.
$Bugzilla_Product1 = Bugzilla::Product=HASH(0x7e3c950);
$ $product->name
Took 0.000483036041259766 seconds.
Firefox
It supports tab completion for file names, method names and so on. For more information see `Devel::REPL`_.
You can use the 'p' command (provided by `Data::Printer`_) to inspect variables as well.
.. code-block:: plain
$ p @INC
[
[0] ".",
[1] "lib",
[2] "local/lib/perl5/x86_64-linux-thread-multi",
[3] "local/lib/perl5",
[4] "/home/vagrant/perl/lib/perl5/x86_64-linux-thread-multi",
[5] "/home/vagrant/perl/lib/perl5",
[6] "/vagrant/local/lib/perl5/x86_64-linux-thread-multi",
[7] "/vagrant/local/lib/perl5",
[8] "/usr/local/lib64/perl5",
[9] "/usr/local/share/perl5",
[10] "/usr/lib64/perl5/vendor_perl",
[11] "/usr/share/perl5/vendor_perl",
[12] "/usr/lib64/perl5",
[13] "/usr/share/perl5",
[14] sub { ... }
]

Docker Container
================
This repository is also a runnable docker container.
Container Arguments
-------------------
Currently, the entry point takes a single command argument.
This can be **httpd** or **shell**.
httpd
This will start apache listening for connections on ``$PORT``
shell
This will start an interactive shell in the container. Useful for debugging.
Environmental Variables
-----------------------
PORT
This must be a value >= 1024. The httpd will listen on this port for incoming
plain-text HTTP connections.
Default: 8000
BMO_db_driver
What SQL database to use. Default is mysql. List of supported databases can be
obtained by listing Bugzilla/DB directory - every module corresponds to one
supported database and the name of the module (before ".pm") corresponds to a
valid value for this variable.
BMO_db_host
The DNS name or IP address of the host that the database server runs on.
BMO_db_name
The name of the database.
BMO_db_user
The database user to connect as.
BMO_db_pass
The password for the user above.
BMO_site_wide_secret
This secret key is used by your installation for the creation and
validation of encrypted tokens. These tokens are used to implement
security features in Bugzilla, to protect against certain types of attacks.
It's very important that this key is kept secret.
BMO_inbound_proxies
This is a list of IP addresses that we expect proxies to come from.
This can be '*' if only the load balancer can connect to this container.
Setting this to '*' means that BMO will trust the X-Forwarded-For header.
BMO_memcached_namespace
The global namespace for the memcached servers.
BMO_memcached_servers
A list of memcached servers (ip addresses or host names). Can be empty.
BMO_shadowdb
The database name of the read-only database.
BMO_shadowdbhost
The hotname or ip address of the read-only database.
BMO_shadowdbport
The port of the read-only database.
BMO_apache_size_limit
This is the max amount of unshared memory (in kb) that the apache process is
allowed to use before Apache::SizeLimit kills it.
HTTPD_StartServers
Sets the number of child server processes created on startup.
As the number of processes is dynamically controlled depending on the load,
there is usually little reason to adjust this parameter.
Default: 8
HTTPD_MinSpareServers
Sets the desired minimum number of idle child server processes. An idle
process is one which is not handling a request. If there are fewer than
MinSpareServers idle, then the parent process creates new children at a
maximum rate of 1 per second.
Default: 5
HTTPD_MaxSpareServers
Sets the desired maximum number of idle child server processes. An idle
process is one which is not handling a request. If there are more than
MaxSpareServers idle, then the parent process will kill off the excess
processes.
Default: 20
HTTPD_MaxClients
Sets the maximum number of child processes that will be launched to serve requests.
Default: 256
HTTPD_ServerLimit
Sets the maximum configured value for MaxClients for the lifetime of the
Apache process.
Default: 256
HTTPD_MaxRequestsPerChild
Sets the limit on the number of requests that an individual child server
process will handle. After MaxRequestsPerChild requests, the child process
will die. If MaxRequestsPerChild is 0, then the process will never expire.
Default: 4000
Persistent Data Volume
----------------------
This container expects /app/data to be a persistent, shared, writable directory
owned by uid 10001. This must be a shared (NFS/EFS/etc) volume between all
nodes.
