graph parser: expire-all ?

[oliver-sanders]

The expire-all trigger (valid at Cylc 7) appears to be missing from Cylc 8:

cylc-flow/cylc/flow/graph_parser.py

Lines 105 to 116 in 76762bb

	QUAL_FAM_SUCCEED_ALL = "succeed-all"
	QUAL_FAM_SUCCEED_ANY = "succeed-any"
	QUAL_FAM_FAIL_ALL = "fail-all"
	QUAL_FAM_FAIL_ANY = "fail-any"
	QUAL_FAM_FINISH_ALL = "finish-all"
	QUAL_FAM_FINISH_ANY = "finish-any"
	QUAL_FAM_START_ALL = "start-all"
	QUAL_FAM_START_ANY = "start-any"
	QUAL_FAM_SUBMIT_ALL = "submit-all"
	QUAL_FAM_SUBMIT_ANY = "submit-any"
	QUAL_FAM_SUBMIT_FAIL_ALL = "submit-fail-all"
	QUAL_FAM_SUBMIT_FAIL_ANY = "submit-fail-any"

I'm not sure whether expire-all was "officially supported" or just a side-effect of the way the logic worked, however, it seems like a sensible trigger condition to me. I'm not sure whether its removal was intentional, nothing springs to mind.

At Cylc 8 such a trigger would probably required a ? modifier (as succeeded and expired are orthogonal), but should still work.

Pull requests welcome!

Would be helpful in my use case, so thanks for raising this issue @oliver-sanders.

Even worse: #5364

[oliver-sanders]

Bumping back until #5364 is sorted.

[hjoliver]

PR done, bumping the milestone forward again.

This can now be attempted, however, won't necessarily work until #5364
