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)

    CGIWrap 
        http://cgiwrap.unixtools.org/
        http://sourceforge.net/projects/cgiwrap/

    sbox: Put CGI Scripts in a Box 
        http://stein.cshl.org/software/sbox/

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.
