Update

Formula	CI Failure	Version	Status
cucumber-cpp	test	10.14	Unable to install Ruby Gems, cf #66450
boost-python	test	10.15,11.0	Not due to boost version bump, see below

boost-python doesn't have a Big Sur bottle (#65000), so I suspect this just isn't compatible with Xcode 12.

I verified this by testing boost-python against the existing boost formula (pre-version bump) on a GitHub macOS 10.15 runner here: https://github.com/carlocab/homebrew-personal/pull/21/checks?check_run_id=1580808244

The reported error is the same, so the boost-python breakage is not due to the boost version bump.

Non-deterministic Failures (CI-induced?)

These failures sometimes emerge, and sometimes don't. I suspect they are mariadb-type CI failures (ref #66450).

Formula	CI Failure	Version	Error Message
cucumber-cpp	test	10.15,11.0	Unable to contact the wire server at localhost:3902.
freeling	bottle	11.0	gzip: write: No space left on device
widelands	install --build-bottle	11.0	Write failed

For example, in this test run cucumber-cpp errored for 11.0 but not for 10.15. It errored out for both versions with the same error in the previous run. (Neither produced errors on the third-to-the-last run.)

See also fn and frugal failures at #66355.

10.14:

Error: 6 failed steps!
brew test --retry --verbose cucumber-cpp
brew fetch --retry mapnik
brew test --verbose libbitcoin-protocol
brew test --verbose libbitcoin-client
brew test --verbose libbitcoin-explorer
brew test --verbose libbitcoin-server

10.15, 11.0:

Error: 7 failed steps!
brew test --retry --verbose cucumber-cpp
brew fetch --retry mapnik
brew test --verbose libbitcoin-protocol
brew test --verbose libbitcoin-client
brew test --verbose boost-python
brew test --verbose libbitcoin-explorer
brew test --verbose libbitcoin-server

10.14:

Error: 2 failed steps!
brew fetch --retry mapnik
brew test --verbose cucumber-cpp

Ok, guess I wasn't able to fix cucumber-cpp.

[carlocab]

This is the boost-python error:

==> python
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ImportError: dlopen(./hello.so, 2): no suitable image found.  Did find:
	file system relative paths not allowed in hardened programs

[carlocab]

Ok, I don't get why cucumber-cpp got broken on 10.15 and 11.0 again. It already tested fine on those versions on the last full testing run.

[carlocab]

I think this might be ready, @fxcoudert. Test result summary in the first post.

[carlocab]

On a separate note, is there a way to specify depends_on xcode but requiring a maximum xcode version? Because I think that's what boost-python needs.

[fxcoudert]

Thanks @carlocab, merged!
I think we could do a maximum Xcode version with fails_with

[carlocab]

Huh, I thought fails_with was just for build requirements. Let me look into it.
