# Test that the parsing of the .yml metadata format didn't change from last
# released version. This uses the commit ID of the release tags,
# rather than the release tag itself so that contributor forks do not
# need to include the tags in them for this test to work.
#
# This is for running manual tests when changing the metadata format.
# The idea is to test changes using all of the files in
# fdroiddata.git. To run it, do:
#
# cd fdroidserver
# git checkout <latest tag>
# cd ../fdroiddata
# ../fdroidserver/tests/dump_internal_metadata_format.py
# cd ../fdroidserver
# git checkout master
# cd ../fdroiddata
# ../fdroidserver/tests/dump_internal_metadata_format.py
# diff -uw metadata/dump_*
