# This script converts a Slash DB from old-style (pre-June 2004)
# to new-style (June 2004), commonly called the "section-topics"
# rewrite.

# Running this script outputs the SQL necessary to do this.
# The suggested procedure for updating a pre-June-2004 Slash site
# to a post-June-2004 version of the code is this:
#
#  1. back everything up! see the "Back up" directions in the
#     "UNINSTALLING" section of the INSTALL file
#  2. do a 'cvs update' to tag T_2_3_0_156, the last T_2_3_* tag
#  3. do the usual update to a tag:  shut down slashd/apache,
#     apply sql/mysql/upgrades files, restart slashd/apache
#  4. do a 'cvs update' to tag T_2_5_0_4, the first bugfixed
#     T_2_5_* tag
#  4. run this script and pipe its output to a file
#  5. read that file over and try to make sure it makes sense for
#     your site (yes, this is pretty subjective)
#  6. shut down slashd and apache
#  7. pipe the file with this script's output to mysql
#  8. errors? resolve them (again, subjective, sorry)
#  9. 'make install'
# 10. run utils/convertDBto200406_suggest, which will offer
#     suggestions for making your topic tree simpler, which you
#     should do but can ignore if you prefer
# 11. run utils/convertDBto200406_render
# 12. start up slashd and apache and make sure the site works OK
#
# After that's done, you can continue along the usual upgrade
# path in the T_2_5_* series.
#
# However, since these instructions were only added to this file
# around T_2_5_0_46, you probably want to save a copy of them so
# when you cvs update this file to T_2_5_0_4 they don't go away :)
#
# As of T_2_5_0_46, there are still bugs in this upgrade process.
# I'm not sure what they are though.  If someone wants to give me
# a detailed description of difficulties encountered, I'll do my
# best to fix them as time permits.  - Jamie

# The steps above created new tables.  The steps below modify your
# existing tables in place.  Only proceed if you are ready.

# All done.  Look over the above SQL, execute it into your DB, and
# check for errors.  If you're certain it's right, then doublecheck
# that you have a valid mysqldump of your existing DB, then:

# RENAME TABLES accesslog TO accesslog_old, accesslog_admin TO accesslog_admin_old, blocks TO blocks_old, discussions TO discussions_old, stories TO stories_old, story_param TO story_param_old, story_text TO story_text_old, story_topics TO story_topics_old, submissions TO submissions_old, templates TO templates_old, topics TO topics_old, topic_images TO topic_images_old, stats_daily TO stats_daily_old, menus TO menus_old, story_files TO story_files_old, pollquestions TO pollquestions_old, auto_poll TO auto_poll_old;
# RENAME TABLES accesslog_admin_new TO accesslog_admin, accesslog_new TO accesslog, blocks_new TO blocks, discussions_new TO discussions, skin_colors_new TO skin_colors, skins_new TO skins, stories_new TO stories, story_dirty_new TO story_dirty, story_param_new TO story_param, story_text_new TO story_text, story_topics_chosen_new TO story_topics_chosen, story_topics_rendered_new TO story_topics_rendered, submissions_new TO submissions, templates_new TO templates, topic_nexus_extras_new TO topic_nexus_extras, topic_nexus_new TO topic_nexus, topic_nexus_dirty_new TO topic_nexus_dirty, topic_parents_new TO topic_parents, topics_new TO topics, stats_daily_new TO stats_daily, menus_new TO menus, story_files_new TO story_files, pollquestions_new TO pollquestions, auto_poll_new TO auto_poll;

# If you encounter any errors related to FOREIGN KEYs, you should
# ALTER TABLE to remove those keys from the relevant tables.
# (Various issues, mostly related to MyISAM being required for
# FULLTEXT indexing but not supporting FOREIGN KEYs, have led us
# to remove all FOREIGN KEYs from Slash.)

# The next two commands should only be issued on your search DB,
# which may or may not be the same as the master DB you've
# been issuing the other commands on:
# ALTER TABLE story_text TYPE=MyISAM, ADD FULLTEXT title (title), ADD FULLTEXT intro_body (introtext,bodytext);
# ALTER TABLE submissions TYPE=MyISAM, ADD FULLTEXT subj (subj,story);

# If you don't want to do error checking
# ALTER TABLE stories DROP COLUMN writestatus;

# Then 'make install' the June 2004 code.

# Then run utils/convertDBto200406_render to convert story_topics_chosen
# to story_topics_rendered.
#
# To compare number of stories in each section pre and post conversion run utils/compareSecPrePost200406
# This will help verify you have your topic tree set up in a sensible manner
#
# Once you're REALLY happy with everything, DROP TABLE *_old
