#
# Perl script to convert a GNATS database to a Bugzilla database.
# This script generates a file that contains SQL commands for MySQL.
# This script DOES NOT MODIFY the GNATS database.
# This script DOES NOT MODIFY the Bugzilla database.
#
# Usage procedure:
#   1) Regenerate the GNATS index file.  It sometimes has inconsistencies,
#      and this script relies on it being correct.  Use the GNATS command:
#        gen-index --numeric --outfile=$GNATS_DIR/gnats-db/gnats-adm/index
#   2) Modify variables at the beginning of this script to match
#      what your site requires.
#   3) Modify translate_pr() and write_bugs() below to fixup mapping from
#      your GNATS policies to Bugzilla.  For example, how do the
#      Severity/Priority fields map to bug_severity/priority?
#   4) Run this script.
#   5) Fix the problems in the GNATS database identified in the output
#      script file gnats2bz_cleanup.sh.  Fixing problems may be a job
#      for a custom perl script.  If you make changes to GNATS, goto step 2.
#   6) Examine the statistics in the output file gnats2bz_stats.txt.
#      These may indicate some more cleanup that is needed.  For example,
#      you may find that there are invalid "State"s, or not a consistent
#      scheme for "Release"s.  If you make changes to GNATS, goto step 2.
#   7) Examine the output data file gnats2bz_data.sql.  If problems
#      exist, goto step 2.
#   8) Create a new, empty Bugzilla database.
#   9) Import the data using the command:
#      mysql -uroot -p'ROOT_PASSWORD' bugs < gnats2bz_data.sql
#   10) Update the shadow directory with the command:
#       cd $BUGZILLA_DIR; ./processmail regenerate
#   11) Run a sanity check by visiting the sanitycheck.cgi page.
#   12) Manually verify that the database is ok.  If it is not, goto step 2.
#
# Important notes:
#   Confidential is not mapped or exported.
#   Submitter-Id is not mapped or exported.
#
# Design decisions:
#   This script generates a SQL script file rather than dumping the data
#     directly into the database.  This is to allow the user to check
#     and/or modify the results before they are put into the database.
#   The PR number is very important and must be maintained as the Bugzilla
#     bug number, because there are many references to the PR number, such
#     as in code comments, CVS comments, customer communications, etc.
#   Reading ENUMERATED and TEXT fields:
#     1) All leading and trailing whitespace is stripped.
#   Reading MULTITEXT fields:
#     1) All leading blank lines are stripped.
#     2) All trailing whitespace is stripped.
#     3) Indentation is preserved.
#   Audit-Trail is not mapped to bugs_activity table, because there
#     is no place to put the "Why" text, which can have a fair amount
#     of information content.
#
# 15 January 2002 - changes from Andrea Dell'Amico <adellam@link.it>
#
#     * Adapted to the new database structure: now long_descs is a 
#       separate table.
#     * Set a default for the target milestone, otherwise bugzilla
#       doesn't work with the imported database if milestones are used.
#     * In gnats version 3.113 records are separated by "|" and not ":".
#     * userid "1" is for the bugzilla administrator, so it's better to
#       start from 2.
