# mkgroovy.sh - create a groovymame diff, if possible.
|
|
|
|
# Since the groovymame author switched to github, there are no more
|
|
# groovymame diffs to download (the ones that used to be hosted on
|
|
# google drive). This rather ugly script just uses the github API to
|
|
# get a diff we can apply.
|
|
|
|
# Note: in my testing, requesting the same diff repeatedly from
|
|
# the API results in identical files, but I'm not sure this is
|
|
# guaranteed. It only matters if you're repeatedly test-running
|
|
# this script, really.
|
|
|
|
# The github 'compare' API is basically just a wrapper for the git
|
|
# command, run on a remote repo. We can use it to download a diff
|
|
# between 2 tags, without having to clone the repo (save a ton of
|
|
# time and bandwidth).
|
|
|
|
# To understand this, see the github API docs: https://docs.github.com/en/rest/
|
|
|
|
# to see info on the repo:
|
|
# curl -H "Accept: application/vnd.github.v3+json" 'https://api.github.com/users/antonioginer/repos'
|
|
|
|
# to get a list of releases:
|
|
# curl -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/antonioginer/GroovyMAME/releases
|
|
# looks like these are in chronological order, newest first.
|
|
|
|
# DIFFURL should end up looking like this:
|
|
# curl -H "Accept: application/vnd.github.v3.diff" 'https://api.github.com/repos/antonioginer/GroovyMAME/compare/{mame0237}...{gm0237sr002e}'
|
|
|
|
# Note: 'git diff' doesn't include timestamps in its output,
|
|
# and there's no way to make the gh API include them. To
|
|
# get ccache to play nice, I have to add the timestamps to
|
|
# the context headers in the diff myself. AFAICT, that's the
|
|
# only way to get ccache to play nice with this patch. Even with
|
|
# CCACHE_SLOPPINESS=include_file_mtime, it complains that the headers
|
|
# have a different modification time than what was expected, on the
|
|
# 2nd (cached) build. I'm pretty sure this only happens because mame
|
|
# uses a precompiled header, and ccache's precompiled header support
|
|
# isn't quite perfect yet. The timestamps I put in the patch are just
|
|
# the release date of the tag. They're not quite in the same format
|
|
# 'diff' produces, but 'patch' accepts them just fine.
