# Bugzilla: Create a new bug via email
###############################################################
# The email needs to be feeded to this program on STDIN. 
# This is usually done by having an entry like this in your 
# .procmailrc:
# 
#     BUGZILLA_HOME=/usr/local/httpd/htdocs/bugzilla
#     :0 c
#     |(cd $BUGZILLA_HOME/contrib; ./bug_email.pl)
# 
#
# Installation note:
#
# You need to work with bug_email.pl the MIME::Parser installed.

###############################################################

# 02/12/2000 (SML)
# - updates to work with most recent database changes to the bugs database
# - updated so that it works out of bugzilla/contrib
# - initial checkin into the mozilla CVS tree (yay)

# 02/13/2000 (SML)
# - email transformation code.  
#   EMAIL_TRANSFORM_NONE does exact email matches
#   EMAIL_TRANSFORM_NAME_ONLY matches on the username 
#   EMAIL_TRANSFORM_BASE_DOMAIN matches on the username and checks the domain of
#    to see that the one in the database is a subset of the one in the sender address
#    this is probably prone to false positives and probably needs more work.

# 03/07/2000 (SML)
# - added in $DEFAULT_PRODUCT and $DEFAULT_COMPONENT.  i.e., if $DEFAULT_PRODUCT = "PENDING",
#    any email submitted bug will be entered with a product of PENDING, if no other product is
#    specified in the email.

# 10/21/2003 (Ludovic)
# - added $DEFAULT_VERSION, similar to product and component above
# - added command line switches to override version, product, and component, so separate
#   email addresses can be used for different product/component/version combinations.
#   Example for procmail:
#    # Feed mail to stdin of bug_email.pl
#    :0 Ec
#    * !^Subject: .*[Bug .*]
#    RESULT=|(cd $BUGZILLA_HOME/contrib && ./bug_email.pl -p='Tier_3_Operations' -c='General' )

# Next round of revisions :
# - querying a bug over email
# - appending a bug over email
# - keywords over email
# - use the globals.pl parameters functionality to edit and save this script's parameters
# - integrate some setup in the checksetup.pl script
# - gpg signatures for security

# 
# 0 - Its an error, but bugzilla can process the bug. The user should
#     handle that as a warning.

# 1 - Its a real bug. Bugzilla cant store the bug. The mail has to be
#     resent.
