Add an onerror="ignore" option to the attach command.

[Stefan Ruppert <stefan.ruppert@…>]

Is it possilbe to extend the attach command with an attribute onerror="ignore"?

I want to attach a tar archive of log files of all failed tests. If no tests failed I don't want to attach an empty tar archive!

(Copied in my alternative implementation notes from the mailing list:)

The common way of handling such a use case is to add the attach into its own step after running your test step, and then ignore any errors for this step - that way you wrap the command in an "ignore" handler. I'm a bit hesitant about adding such features at command-level, but rather think that if there was limitations at step-level it should be resolved there for the benefit of running any command. As a suggestion it may be that we implement an onerror="strip" type argument for step that just completely ignores the step if errors occur - nothing gets reported.

If you then add your attachment in such a step you can first try to attach and then echo a line like "Failures uploaded".

• if no file, nothing gets reported.
• if file, the file is uploaded and your echo is written to the log.
