Tinderbox Documentation:
|
|
------------------------
|
|
|
|
* Every directory has a ReadMe file which tells about all the files
|
|
in that directory.
|
|
|
|
* Every executable can be run with --help so that you can see what
|
|
the program does and what its arguments are. If you have trouble
|
|
running the file just look at the file in a text editor and find
|
|
the string "usage".
|
|
|
|
* The top of every file (both code and configuration) has a short
|
|
explanation of what this file does.
|
|
|
|
* The code has lots of documentation so you can read the code if you
|
|
need more details about how something works.
|
|
|
|
|
|
To install:
|
|
-----------
|
|
|
|
NOTE: You will need to ensure that Perl is installed on your web server.
|
|
It would be a good idea to have these modules installed:
|
|
|
|
Storable, Date::Format,
|
|
|
|
You can easily check if these are installed by executing these
|
|
following commands. If the module is installed, you'll get no
|
|
output:
|
|
|
|
perl -e 'use Storable'
|
|
perl -e 'use Date::Format'
|
|
|
|
|
|
Read the Policies and Overview documents found in this directory to
|
|
help you get a feel for the scope of this installation.
|
|
|
|
The process id which receives and process the mail must be the
|
|
same id which runs the Tinderbox cron job to prepare the web pages.
|
|
|
|
A good practice is to configure the web server so that all CGI scripts
|
|
do not run as the same user. Using one user id can cause security
|
|
problems which are hard to detect. If you must run all web applications
|
|
as a single user it would be safer to ensure that this user is a specific
|
|
web user (apache, cgiuser, webuser) so that this is not mixed up with other
|
|
unix system users (daemon, nobody, bin) since this could cause security
|
|
interactions with other programs which use these ids.
|
|
|
|
It may take some thought as to how the user id will be configured to
|
|
run when receiving mail and when receiving web requests and not be a
|
|
user id which will cause security problems.
|
|
|
|
These products will help partition your web application to run as
|
|
different users. (See http://www.w3.org/Security/Faq/wwwsf4.html for
|
|
more info)

|
|
|
|
The Apache Web server comes with its own wrapper script called suEXEC.
|
|
|
|
The src/default_conf directory contains Perl libraries which are
|
|
specific to an individual users site configuration. No two users of
|
|
Tinderbox2 will have the identical sets of files.
|
|
|
|
The files found in default_conf are sample files which are used at
|
|
Mozilla.org. Other users are expected to customize these libraries and
|
|
install the modified libraries in local_conf. Files found in
|
|
local_conf will be used before any file found in default_conf.
|
|
The distribution of Tinderbox2 will never place any files in the
|
|
local_conf directory as this is assumed to be under local control.
|
|
|
|
A quick overview of the files:
|
|
|
|
TinderConfig.pm
|
|
general configuration settings: HTML directories, Log files,
|
|
implementations of libraries to use, etc
|
|
|
|
TreeData.pm
|
|
version control (CVS, Bonsai) configuration
|
|
|
|
Error_Parse.pm
|
|
the regular expressions for identifying errors in build logs.
|
|
|
|
BTData.pm
|
|
bug tracking configuration
|
|
|
|
FileStructure.pm
|
|
filesystem (storage) and global/per-project settings.
|
|
Most users will not have to change this.
|
|
|
|
In particular you will need a TinderConfig.pm and a TreeData.pm which
|
|
describes your local setup. You may need to make local versions of
|
|
the other files depending on how you wish to have Tinderbox configured.
|
|
|
|
1. Run ./configure. When configure is done you will have a Makefile
|
|
and a config.out. Although Tinderbox2 consists entirely of Perl
|
|
scripts we must substitute some values into the source code to make it
|
|
executable. You may wish to change the default directories in
|
|
configure for some of the Makefile variables. Please read config.out
|
|
and make any changes which need to be made for your system. Configure
|
|
also accepts command line options to change some default variables.
|
|
Please look at the configure source code for variable details, but the
|
|
most common changes are:
|
|
|
|
--prefix
|
|
the directory for most of the tinderbox files.
|
|
Defaults to /home/tinderbox2
|
|
|
|
--cgibin-prefix
|
|
The directory where cgi scripts will be run.
|
|
This depends on how your web server is configured.
|
|
For security you may wish to ensure that this directory is
|
|
disjoint from the prefix directory.
|
|
Defaults to /var/www/cgi-bin/tinderbox.
|
|
|
|
--html-prefix
|
|
The directory where html files should be written.
|
|
This depends on how your web server is configured.
|
|
This is where the web server will pick up Tinderbox2 output.
|
|
Defaults to /home/httpd/html/tinderbox.
|
|
|
|
2. Run 'make' to create executable versions of the source code in the
|
|
./build directory.
|
|
|
|
3. Run 'make compile_bin_code' to ensure that the code will compile
|
|
when it is installed. This will not work if your target machine is
|
|
very different from the machine you are running make on.
|
|
|
|
4. If you wish run the test programs as described in /build/test/ReadMe
|
|
to ensure that you have configured the program correctly. This will
|
|
require a TinderConfig.pm file in your local_conf directory.
|
|
|
|
See the ReadMe file in the test directory for detailed information
|
|
on how the tests work.
|
|
|
|
5. Run 'make install' to install Tinderbox2 on your system. You may
|
|
wish to run this with a different 'prefix'
|
|
|
|
make install --prefix=/opt/tinderbox
|
|
|
|
It is currently assumed that the bin directory of your installation
|
|
will be where the web server will run the Tinderbox2 cgi's from.
|
|
You can copy the *.cgi files to another directory if this is not
|
|
the case.
|
|
|
|
5. There are some gifs located in the gif directory which have
|
|
historically been used by Tinderbox2. The installation via
|
|
'make install' does not install these images. Put them
|
|
somewhere in your web server's html directory if you wish to
|
|
use them. Samples of their use are in the configuration files.
|
|
|
|
6. Set up a cron job to run the following every five minutes:
|
|
|
|
$cgi-bin/bin/tinder.cgi --daemon-mode
|
|
|
|
This generates the static tinderbox pages which users see.
|
|
|
|
Set up a cron job to run the following at least once a day:
|
|
|
|
$prefix/bin/rmlogs
|
|
|
|
Six am is a good time to run this as the machine load is usually
|
|
light and will avoids any Daylight Savings problems. This keeps
|
|
the archive of compressed build logs from growing without limit.
|
|
|
|
7. You may receive data into the $prefix/bin/processmail* programs via
|
|
http post. Typically this means that these programs must be installed
|
|
in the $cgi-bin directory and have a name which ends in *.cgi. Instead
|
|
of mailling the logs to these programs, use the HTTPPost program to
|
|
post the data to the correct URL.
|
|
|
|
8. If using the mail system, set up the $prefix/bin/processmail*
|
|
programs to receive the incoming tinderbox mail. The process id which
|
|
receives and process the mail must be the the same id which runs the
|
|
Tinderbox2 cron job to prepare the web pages. Usually this set up is
|
|
accomplished by having the MTA (Sendmail) pass mail for particular
|
|
accounts into a script. This can be configured via a global
|
|
configuration file (Sendmail alias file) or via a .forward file (each
|
|
account gets the same user id but a different home directory, each
|
|
home directory gets a .forward to cause incoming mail to be delivered
|
|
through the correct tinderbox mail processing program).
|
|
|
|
The following configuration has been tested for the mail server
|
|
Postfix. The postfix aliases file /etc/postfix/aliases contains the
|
|
following lines. This file must be processed with a /usr/sbin/postalias
|
|
command which must be run by the same id which will run the Tinderbox2
|
|
cgi scripts.
|
|
|
|
tinderbox_builds: |/home/tinderbox2/bin/processmail_builds
|
|
tinderbox_bugzilla: |/home/tinderbox2/bin/processmail_bugs
|
|
|
|
If it is not possible to have mail delivery on your web machine and to
|
|
have your web machine deliver specific mail through a program then you
|
|
could you use fetchmail to simulate this delivery format.
|
|
|
|
Download fetchmail (from http://tuxedo.org/~esr/fetchmail) and install
|
|
it on your web server. Have the mail sent to any pop/imap mail server
|
|
which is accessible from the web server. Configure fetchmail to gather
|
|
the mail from the mail server and pass it through to the correct mail
|
|
processing program. You should keep the polling interval short
|
|
(30-200 seconds) as long polling intervals will cause delays in the
|
|
Tinderbox2 system and limit how quickly users see the new data. If
|
|
the polling interval is too short then you will overload your pop
|
|
server with needless queries. Fetchmail should run under the same
|
|
id as the Tinderbox2 server. The fetchmail configuration file will
|
|
look something like:
|
|
|
|
poll mail.provider.net with proto pop3:
|
|
user "tinderbox_builds" there has password "u can't krak this"
|
|
is tinder here and wants mda "$prefix/bin/processmail_builds"
|
|
|
|
A common mail address is 'tinderbox_builds' for build information
|
|
destined for the web server. Similarly the bug tracking system should
|
|
send mail to 'tinderbox_bugs'.
|
|
|
|
9. For CVS systems - make sure that when Tinderbox2 runs it has all the
|
|
permissions that it needs to access the Version Control database.
|
|
This usually means having an environment variable set when Tinderbox2
|
|
is run from cron. If you are using VC_CVS.pm then you will need to put
|
|
a ~/.cvspass for the Tinderbox2 server to use.
|
|
|
|
To create this file you will need to Log into the CVS repository
|
|
yourself, once for each tree you have defined. The login command must
|
|
use the hostname/modules exactly as you wrote it in VCData. Then copy
|
|
your ~/.cvspass into the Tinderbox2 server user id's home directory.
|
|
This must be the REAL home of the Tinderbox2 daemon, as listed in
|
|
/etc/passwd/ and set in the $HOME environmental variable for tinder.cgi.
|
|
The file must not be world readable or writable or executable.
|
|
|
|
It is recommended that VC_CVS.pm is only used as an interim step in
|
|
setting up VC_Bonsai. VC_Bonsai is not hard to setup and provided many
|
|
useful features which are absent in VC_CVS.pm.
|
|
|
|
For SVN systems - make sure that the when Tinderbox2 runs it has access
|
|
to the "svn log" command and that command can access the repository as
|
|
defined in TreeData.pm. If the svn repository is local to the Tinderbox2
|
|
server then you can specify the repository using file:/// - if it is
|
|
remote, then use either http:// or svn+ssh:// as required.
|
|
|
|
10. Configure the build machines to mail their build logs (with Tinderbox2
|
|
variables on the top) to the web server machine. New builds must not
|
|
start earlier than 6 minutes after the last build started. Each build
|
|
machine mails the build log of each build and puts some build data at
|
|
the top of the log. Build information includes whether the build was
|
|
a success, which error parsers to use on the log file and what build
|
|
this is.
|
|
|
|
Run 'processmail_builds --help' to learn about how the mail
|
|
processing system works and what the mail messages are expected to
|
|
look like. There is an example mail in the test directory called
|
|
samplelog. The clientbin directory contains code which can be used on
|
|
the buildmachine.
|
|
|
|
See the README to help setup your build machine.
|
|
|
|
http://www.ntsendmail.com/ has a Perl program which can be used to
|
|
send mail on systems where there is no sendmail installed.
|
|
|
|
There is nothing special about sending mail. Any data transport layer
|
|
would work including HTTP Post and SSH the only requirement is that
|
|
the data is sent to the STDIN of the mail processing programs upon
|
|
delivery and that the process which runs this is the same uid as the
|
|
Tinderbox2 server.
|
|
|
|
Alternate delivery mechanisms have not been explored thoroughly but
|
|
they should not be too hard to setup. There is a set of instructions
|
|
for this in lwpcook.pod which suggest you will need to install
|
|
HTTP::Request::Common and LWP::UserAgent;
|
|
|
|
11. Set up the bug tracking system to send mail to 'tinderbox_bugs' on
|
|
the web server machine whenever a Bug ticket changes state. It is not
|
|
interesting to see which tickets are being worked on, so restrict
|
|
mailing to changes in ticket state not updates (edit) of a ticket.
|
|
|
|
12. Check that the time on your web server, your version control
|
|
machine, your bug tracking machine and your build machines are all in
|
|
sync. Check that if build mail bounces on any of the above
|
|
machines that it will be received by someone who can act on it.
