[RFC PATCH] travis-ci: work around quarantine error during Perforce install on macOS

SZEDER Gábor· Sep 7, 2018, 03:20 UTC · lore

Homebrew recently enabled the quarantine feature, which breaks a lot of things [1], including installing Perforce in our macOS build jobs on Travis CI [2], breaking all those builds in the last couple of days.

The suggested workaround is to install affected packages using the '--no-quarantine' option, but adding it to the current command, i.e. running:

  brew install --no-quarantine caskroom/cask/perforce

doesn't work, because apparently the '--no-quarantine' option is not propagated when the command gets converted to:

  brew cask install perforce

(unlike other options, e.g. '--verbose', '--force', and '--debug', which are propagated properly).

So work around the issue by installing Perforce with this command instead:

  brew cask install --no-quarantine perforce

Note that one option homebrew/cask devs are considering is to roll back quarantine altogether [3]. We might have to revisit this workaround if they eventually end up doing that, as that might remove the '--no-quarantine' options as well. We'll see.

I'm not quite sure how to handle this issue.

First: I don't have a Mac, and this "cute" homebrew talk about pouring
bottles and tappping casks in the caskroom makes my brain hurt; so I
was just following instructions without fully understanding what I was
doing.  Nonetheless, this patch apparently makes the macOS build jobs
work again.

OTOH, this is only an auxillary part of Git, so fast-tracking it is fairly low-risk, and by doing so we might have an all-green CI build before the 2.19 release.

Finally, if we wait long enough, then this whole issue might just solve itself, if the homebrew devs revert this quarantine stuff, and our current 'brew install' command might suddenly work again.

Good, we waited long enough, and this issue apparently did indeed just solve itself :)
