#!/bin/bash

# Used to compare sstate checksums between MACHINES.
# Execute script and compare generated list.M files.
# Using bash to have PIPESTATUS variable.

# It's also usefull to keep older sstate checksums
# to be able to find out why something is rebuilding
# after updating metadata

# $ diff \
#     sstate-diff/1349348392/fake-cortexa8/list.M \
#     sstate-diff/1349348392/fake-cortexa9/list.M \
#     | wc -l
# 538

Welcome to utility to compare sstate checksums between different MACHINEs.
$0 <OPTION>

Options:
  -h, --help
        Display this help and exit.

  --tmpdir=<tmpdir>
        Specify tmpdir, will use the environment variable TMPDIR if it is not specified.
        Something like /OE/oe-core/tmp-eglibc (no / at the end).

  --machines=<machines>
        List of MACHINEs separated by space, will use the environment variable MACHINES if it is not specified.
        Default value is "qemuarm qemux86 qemux86-64".

  --targets=<targets>
        List of targets separated by space, will use the environment variable TARGETS if it is not specified.
        Default value is "core-image-base".

  --analyze
        Show the differences between MACHINEs. It assumes:
        * First 2 MACHINEs in --machines parameter have the same TUNE_PKGARCH
        * Third optional MACHINE has different TUNE_PKGARCH - only native and allarch recipes are compared).
        * Next MACHINEs are ignored
