Subject [jira] [Issue Comment Edited] (DAEMON-240) Undocumented and inconsistent behaviour of multi-valued registry entries
Date Mon, 06 Feb 2012 18:19:59 GMT

    [ https://issues.apache.org/jira/browse/DAEMON-240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13201358#comment-13201358

------------------------------------------------------------

Resolved by ensuring that --option rests the parser state.
1. In case --option ++option ... is used the resulting
   value will be overwritten with those command line (combined)
2. In case ++option ++option ... is used the resulting
   value will be appended to existing one.
3. ++option=a --option=b will cause that any options on
   the command line before last -- are dropped.
   No error or no warning is reported in that case.

                
      was (Author: mturk@apache.org):
    Resolved by disabling intermixing -- and ++ options on the same command line.
This means that either --option or any number of ++option can be used, but not together

> The behaviour of option processing for multi-valued registry entries is partly undocumented,
and inconsistent.
> --Option and ++Option are only documented in the context of a single invocation of procrun.
> The documentation should be updated to clarify that ++Option can be used in a separate
invocation of procrun (update service) to append values to the registry.
> ==
> The documentation implies that --Option resets the value.
> This is only true if the ++Option is not used at the same time - if the ++Option is used
anywhere on the command-line, then all the options are appended to any existing value in the
registry.
> The behaviour of mixed --Option and ++Option should either be fixed so that --Option
clears any existing settings, or the existing behaviour should be documented.
