Dependencies during boostrapping (R1 tasks)

Cylc Cylc 8 Migration

Hi @fredw

OK, the expire trigger is currently broken, sorry. It has already been fixed as part of the manual intervention enhancements to be released soon in 8.3.0.

Expire triggers are pretty niche at my site, but your case for extensive use makes good sense. If you have a desperate need for it, before 8.3.0 comes out, I could tell you how to patch your current version.

Here’s a standalone test workflow to show the problem:

 $ cat flow.cylc
[scheduling]
    initial cycle point = previous(T00)
    [[special tasks]]
        clock-expire = foo(PT0S)
    [[graph]]
        R1 = """
           foo => bar
           foo:expired? => baz
        """
[runtime]
    [[foo, bar, baz]]

The task foo expires immediately, which should trigger baz, but at the moment it does not:

[I] (venv) ~/c/exp $ cylc vip --no-detach --no-timestamp
$ cylc validate /home/oliverh/cylc-src/exp
Valid for cylc-8.2.3
$ cylc install /home/oliverh/cylc-src/exp
INSTALLED exp/run7 from /home/oliverh/cylc-src/exp
$ cylc play --no-detach --no-timestamp exp/run7
