bug 1442306 added code to generate a buildhub.json file during packaging. Unfortunately it doesn't work for l10n repacks, which is something we do want. I'm splitting this off to a separate bug so I can land the patches on that bug.

Pardon intrusion, but can I ask what the status of this is. In https://bugzilla.mozilla.org/show_bug.cgi?id=1443873 we're waiting for Mihai to wrap up the work of fixing the download.url and making sure the actual buildhub.json file gets uploaded. Is there anything I can do to help on this bug?

I noticed Mihai's update, is buildhub.json now being generated for l10n repacks?

Any progress on this on Ted?

I went around and around on this a few times and couldn't figure out a reasonable place to put this (seemingly simple) logic in the rat's nest that is our l10n repack setup. I know this is blocking useful work on the buildhub side so I talked to Callek today about a potential implementation and he seemed OK with it. We currently have `EN_US_BINARY_URL` defined to point to the en-US package in l10n repack tasks: https://dxr.mozilla.org/mozilla-central/rev/c291143e24019097d087f9307e59b49facaf90cb/taskcluster/ci/l10n/kind.yml#108 We could similarly define an `EN_US_BUILDHUB_URL` there to point to the en-US buildhub.json. Then we would fetch that buildhub.json file when we fetch the en-US package: https://dxr.mozilla.org/mozilla-central/rev/c291143e24019097d087f9307e59b49facaf90cb/testing/mozharness/scripts/desktop_l10n.py#353 I'd just do it directly in the mozharness Python instead of trying to wire it into the build system. Then, somewhere in the `make_upload` function in the mozharness script we'd read the en-US buildhub.json and update the target.locale and download.* keys that differ from en-US: https://dxr.mozilla.org/mozilla-central/rev/c291143e24019097d087f9307e59b49facaf90cb/testing/mozharness/scripts/desktop_l10n.py#444-502 The only finicky bit there would be determining the installer/package filename, since mozharness and the build system are kind of at arm's length here. I think that much is manageable though.
