# Hey, what's this?
#
# 'checksetup.pl' is a script that is supposed to run during installation
# time and also after every upgrade.
#
# The goal of this script is to make the installation even more easy.
# It does so by doing things for you as well as testing for problems
# early.
#
# And you can re-run it whenever you want. Especially after Bugzilla
# gets updated you SHOULD rerun it. Because then it may update your
# SQL table definitions so that they are again in sync with the code.
#
# So, currently this module does:
#
#     - check for required perl modules
#     - set defaults for local configuration variables
#     - create and populate the data directory after installation
#     - set the proper rights for the *.cgi, *.html ... etc files
#     - check if the code can access MySQL
#     - creates the database 'bugs' if the database does not exist
#     - creates the tables inside the database if they don't exist
#     - automatically changes the table definitions of older BugZilla
#       installations
#     - populates the groups
#     - put the first user into all groups so that the system can
#       be administrated
#     - changes already existing SQL tables if you change your local
#       settings, e.g. when you add a new platform
#
# People that install this module locally are not supposed to modify
# this script. This is done by shifting the user settable stuff into
# a local configuration file 'localconfig'. When this file get's
# changed and 'checkconfig.pl' will be re-run, then the user changes
# will be reflected back into the database.
#
# Developers however have to modify this file at various places. To
# make this easier, I have added some special comments that one can
# search for.
#
#     To                                               Search for
#
#     add/delete local configuration variables         --LOCAL--
#     check for more prerequired modules               --MODULES--
#     change the defaults for local configuration vars --LOCAL--
#     update the assigned file permissions             --CHMOD--
#     add more MySQL-related checks                    --MYSQL--
#     change table definitions                         --TABLE--
#     add more groups                                  --GROUPS--
#     create initial administrator account             --ADMIN--
#
# Note: sometimes those special comments occur more then once. For
# example, --LOCAL-- is at least 3 times in this code!  --TABLE--
# also is used more than once. So search for every occurence!
#
# To operate checksetup non-interactively, run it with a single argument
# specifying a filename with the information usually obtained by
# prompting the user or by editing localconfig. Only information
# superceding defaults from LocalVar() function calls needs to be
# specified.

# This is quite tricky. But fun!

# First we read the file 'localconfig'. Then we check if the variables we

#
# Why do it this way around?
#
# Assume we will enhance Bugzilla and eventually more local configuration
# stuff arises on the horizon.
#
# But the file 'localconfig' is not in the Bugzilla CVS or tarfile. You

# we can't put it into the CVS/tarfile, can we?
#
# Now, when we need a new variable, we simply add the necessary stuff to
# checksetup. When the user gets the new version of Bugzilla from CVS and
# runs checksetup, it finds out "Oh, there is something new". Then it adds

WARNING! You have not entered a value for the "webservergroup" parameter
in localconfig. This means that certain files and directories which need
to be editable by both you and the webserver must be world writable, and
other files (including the localconfig file which stores your database
password) must be world readable. This means that _anyone_ who can obtain
local access to this machine can do whatever they want to your Bugzilla
installation, and is probably also able to run arbitrary Perl code as the
user that the webserver runs as.

You really, really, really need to change this setting.

# Here we use --CHMOD-- and friends to set the file permissions

# scripts should not be writable for apache, otherwise someone may be possible
# to change the cgi's when exploiting some security flaw somewhere (not
# necessarily in Bugzilla!)
#
# Also, some *.pl files are executable, some are not.

# This abstracts out what files are executable and what ones are not.  It makes

# Not all directories have permissions changed on them.  i.e., changing ./CVS
