SpiderMonkey nightly builds

[anba]

spidermonkey/get-latest-version.js currently only supports Beta builds, but it should also be possible to download Nightly builds:

• Nightly binaries are available at https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/.
• The build-id can either be retrieved by scraping https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/ and searching for one of these files:
  • https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-70.0a1.en-US.linux-x86_64.buildhub.json
  • https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-70.0a1.en-US.linux-x86_64.json
  • https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-70.0a1.en-US.linux-x86_64.txt
  • https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-70.0a1.en-US.linux-x86_64_info.txt
• Or a bit more fancy through buildhub2:
  • For example for linux64 nightly builds:

curl -s -X POST https://buildhub.moz.tools/api/search \
  -d '{"size": 1, "sort": {"build.id": "desc"}, "query": {"bool": {"must": [{"term": {"source.product": "firefox"}}, {"term": {"source.tree": "mozilla-central"}}, {"term": {"target.channel": "nightly"}}, {"term": {"target.platform": "linux-x86_64"}}]}}}'
