#!/bin/bash

# PURPOSE
# This is not a nightly script. You use it to regenerate the model-collections
# if Greenstone has changed fundamentally, such as what HASH OIDs get assigned
# to documents or something that changes the contents of the index and 
# archives folders. This has happened now with the commits 
# http://trac.greenstone.org/changeset/28022 and 
# http://trac.greenstone.org/changeset/28021
# These commits generate new stable HASH OIDs for the existing documents.


# USAGE
# Put this file in the toplevel of the Greenstone 2 binary/compiled SVN installation
# that you want to generate the model collections with.
# You can provide a list of collection names or none, in which case all the collections
# are processed.

# Pass in --svnupdate to copy across the contents of archives and index in the
# rebuilt collection, overwriting their equivalents in the svn model collection,
# but not removing any extraneous HASH folders already present.
# !!!!! IMPORTANT: if you pass in svnupdate, it leaves you to do the final commit on 
# the (svn) model-collect folder!

# Pass in --svndelete to remove the archives and index from svn in the model-collect
# and replace this with the rebuilt archives and index 
# The --svndelete is useful for when the HASH directory naming has changed and everything
# in archives and index has to be wiped out and moved back in from the rebuilt col.
# Passing in --svndelete will do the final commits on the model-collect folder.

# If neither flag is passed in, then the collections are rebuilt but the svn model-collect
# is not updated and the repository is not updated.

# Examples of usage:
# ./gen-model-colls.sh
# ./gen-model-colls.sh --svndelete
# ./gen-model-colls.sh --svnupdate Tudor-Basic Tudor-Enhanced

# The first just rebuilds all the collections in a new folder called collect and stops there

# The second rebuilds all the collections in collect and svn removes the archives and the index 
# folders in model-collect. Then it copies across the rebuilt archives and index into model-collect 
# and svn adds them.

# The third example checks out all the model-collections again, but rebuilds only the 2 collections 
# specified in the new collect folder. Then it copies across the *contents* of the archives and 
# index folders of those 2 collections into their model-collect equivalents. You then still have to 
# do the final svn commit on the model-collect folder after looking over the differences.

# Also valid examples:
# ./gen-model-colls.sh Tudor-Basic Tudor-Enhanced
# ./gen-model-colls.sh --svndelete Tudor-Basic Tudor-Enhanced
# ./gen-model-colls.sh --svnupdate

# PSEUDOCODE
# This script:
# Checks out the model-collections folder from SVN 
# Makes a copy
# In the copy: gets rid of their .svn folders, and builds each collection in turn, moving building to index once done
# If --svndelete was passed in: svn removes model-collect/archives and model-collect/index, copies over collect/index
# and collect/archives into model-collect and svn adds model-collect/archives and model-collect/index. Then SVN COMMITS
# model-collect/archives and model-collect/index.
# If --svnupdate was passed in: copies collect/archives/* into model-collect/archives/*, and copies collect/index/*
# into model-collect/index/*, overwriting files that already existed but have now been updated upon rebuild. However, 
# --svnupdate will leave untouched any files and folders unique to model-collect. No SVN commit, that's LEFT UP TO YOU.

# See earlier version of this script:
# To svn remove what's unique to model-collect and svn add what's been rebuilt in index and archives
