[jira] [Commented] (DAFFODIL-2461) Intermittant test failure in schematron CLI tests

["John Wass (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DAFFODIL-2461?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17270164#comment-17270164 ] 

John Wass commented on DAFFODIL-2461:
-------------------------------------

Looks like an extra command prompt sneaks in there sometimes.  Undefined behavior based on the timing of the output stream reading thread.

Intermittently reproducible locally, should be able to clean it up.

The currently logic was structured to be portable without having to check on the platform.  If nothing else will just add a couple checks in to specific the windows command prompt.

> In a recent GitHub Actions tests, there was a failure with checking the error code of a test:
> https://github.com/apache/incubator-daffodil/pull/477/checks?check_run_id=1745505882#step:10:200
> Based on the output, it's looks like Daffodil did the right thing, but then failed to detect the correct error code. The error makes this clear:
> {quote}
> Error:  Test org.apache.daffodil.schematron.TestEmbedded.extends2 failed: unparseable ec, D:\a\incubator-daffodil\incubator-daffodil>
> {quote}
> This "unparseable ec" is expecting an integer, but instead it got the command prompt. Looking at the output, we can see that we are sending the "echo %errorlevel%" command before we get to the prompt, and our code seems to be accepting the command prompt as a match for the error code.
> Perhaps we need to have an expect that looks for the prompt before sending new line?
