With HOMEBREW_CASK_OPTS="--require-sha", brew bundle exits 0 even if installation is not successful

[weakish]

Provided that HOMEBREW_CASK_OPTS="--require-sha",
even if installation is not successful due to checksum not defined,
brew bundle still exists 0 and not reporting any error.

For example: (chromium cask defines its sha256 checksum as :no_check)

export HOMEBREW_CASK_OPTS="--require-sha"
echo 'cask "chromium"' | brew bundle --file=-

From the output, it seems everything is okay and chromium is installed:

Installing chromium
Homebrew Bundle complete! 1 Brewfile dependency now installed.

Also, the status code is 0.

; echo $?
0

However, in fact chromium is not installed:

; brew info chromium | fgrep 'Not installed'
Not installed

Strangely, running brew bundle with the verbose option, brew exists 1 correctly:

; echo 'cask "chromium"' | brew bundle --file=- --verbose

Error: Cask 'chromium' does not have a sha256 checksum defined and was not installed.
This means you have the --require-sha option set, perhaps in your HOMEBREW_CASK_OPTS.

Wow, what timing — I was just about to file a very similar issue, although in my case the cask install failed due to a pre-existing .app rather than --require-sha. My guess is that both of these have the same root cause, since the same --verbose behavior applies too.

brew bundle check appears unaffected, it reports brew bundle can't satisfy your Brewfile's dependencies. whether run with --verbose or not.

Edit: possibly introduced by fe11409 ?

I can report the same symptoms - brew bundle reports a successful install although one of the packages failed to install for completely unrelated reasons. Manual brew install fails properoy.

[Mike McQuaid]

I expect this should now be resolved. Please verify and respond if not!

[Ian Chamberlain]

Confirmed, after a brew update it seems to be failing as expected, without --verbose:

$ echo 'cask "emacs"' | brew bundle install --file=-; echo $?
