# $Id$
# Acknowledgment:
# The following code is a modified version of an original work written by
# Greg Schafer for the "DIY Linux" project and is included here with his

# ref: http://www.diy-linux.org
#
#
# ---------------------------------------------------------------------------- #
# Here are the ICA functions.
# ---------------------------------------------------------------------------- #
#
# Here we prepare for the Iterative Comparison Analysis (ICA). Essentially, we
# copy most of our chroot phase files to a new location then perform some
# manipulations on the copied files to make diff comparisons easier. The steps
# involved are:-
# (1) copy the whole tree (minus the PRUNEPATH defined below) to the CMP_DIR
# location. Use tar as it seems like the most appropriate tool for copying
# large directory trees around.
# (2) delete all symlinks.
# (3) gunzip all `*.gz' files.
# (4) delete all hardlinked files (of course trying to leaving the "master"
# intact)
# (5) convert all `*.a' files (ar archives) into a directory of the same name
# containing the unpacked object files.
# (6) fully strip the whole lot (but being careful to strip only the debug
# symbols from object `*.o' files).

# The following code is a no-modified version (except for this comment

#
# FARCE: Farce Assists Rebuild Comparison Evaluation ;)
#
# to answer the question "can it rebuild itself?"
#
# We expect four arguments - first directory path, filelist
# containing the files in this directory which we wish to compare,
# second directory path, filelist for second directory.
#
# Yes, we could just compare everything in each tree, but the
# filelist script knows about files it can reasonably ignore,
# and this also allows us to build a sytem, boot it and get a
# list of files, build a full desktop environment, and only then
# build and boot the "can it build itself" test system and get
# _its_ filelist.
#
# What this script aims to do:
# ____________________________
#
# First, report files not in both builds.
#
# Then, confirm symlinks point to same targets.
#
# After that, compare individual files -
# if different, run the file name through 'expected'
# to pick out files that are unlikely to match (logs,
# pids, fstab [assumes '/' is a different device each time],
# count these as 'expected'.
#
# For whatever is left, check the file type - ar archives
# have their members extraced and compared (every member has
# a timestamp), gzipped files are compared beyond their
# timestamp, binaries, at least those using shared libs or
# which are shared objects, are copied and subjected to
# --strip-debug. If files match at this stage, count them as
# 'accepted'.
#
# As a last step for any file that doesn't match, copy it
# through some perl regexps to "process" it (convert any
# date, time, kernel-version information from standard formats
# into tokens, then see if the tokensi match.
#
# For details of the regexps, see the tokenize function.
# Those files that match after this are also counted as
# 'accepted'. Note that I don't always start from the kernel
# version that I'm going to build, so this copes with e.g. perl
# files that hardcode the kernel version.
#
# We now have files that don't match. A few of these seem to be
# common to all builds - some (members of) c++ libraries or ar
# archives, a few programs which perhaps use some sort of c++ code).
# The file name # is passed to the 'failure' function - these
# recognized filenames are labelled as 'predictable FAIL:',
# anything else is labelled as 'unexpected FAIL:'.
#
# output:
# stderr - files only in one of the builds, failure messages,
# and totals.
#
# farce-results - more details, including which files were treated
# as expected differences, files where neither copy could be read,
# files treated as accepted, with the reason (and member for ar
# archives). This data is typically up to 100 characters wide -
# sometimes it's a bit more, but it doesn't wrap too badly in a
# 100 character xterm.
#
# farce-extras - diffs for the files, or members, that didn't
# match. This file is to establish new regexps for picking up
# date/time/kernel-version formats.
#
# farce-identical - the names of the files which are identical
#
# farce-substitutions - whenever using tokenizeanddiff results in a
# difference being accepted, for both versions diff the before and
# after versions to show what got changed. If the file is a binary,
# the output may still be hard to read. Note that I _know_ glibc
# version strings pass one of the regexps looking for a kernel version
# - since I expect you to use the same version of glibc for each
# build, this is not a problem.
#
# farce-differ - the names of the files which could not be treated
# as matching (whether or not I regard the failure as predictable)
# for possible input to ICA processing.
