CompareId == 'undefined'

[Joannazhx]

Is your feature request related to a problem? Please describe.
Hi, Richard
I'm using the overrideBuildReleaseId and it works well. The only issue is, it could only be assigned an int to it.
Could you set a condition in overrideBuildReleaseId that could help me turn on/ off overrideBuildReleaseId in YAML template?

if overrideBuildReleaseId = 'undefined' 
    #do nothing (won't overwrite checkstage setting)
else overrideBuildReleaseId = (int)
   get work items between {comparebuild id} and {current build id}

In this case, I could use the pipeline input variable to choose to turn on/off overrideBuildReleaseId option
overrideBuildReleaseId = $(input)
the input could be 'undefined' or build-id we want to compare with

Thanks a lot for your help!

All the best,
Joanna

Sorry I have read this a few times and don't understand the request.

As it stands the the following is true

overrideBuildReleaseId Value	result
Undefined	Old behaviour, looks for last successful build using optional stage and tag filters
Empty string	Old behaviour, looks for last successful build using optional stage and tag filters
A valid build ID (int)	Use the build ID as the comparison
An invalid build ID (int)	If a valid build cannot be found then the task exits with a message
Any other non empty input value	The task exits with an error meesage

The key design guideline here is that this overrideBuildReleaseId is an exceptional value - it is only used with care by an administrator who understands the implications and ONLY wants to compare against a known fixed build/release. If this build/release cannot be found then no processing should occur. I don't want someone to stumble into enabling this feature within intending to.

So can you not switch the feature on or off by passing a value build ID or not ( passing undefined or empty string) ?

Or have you found a case where my actually logic does not match the above?

Thanks, Richard.
This one is what I'm looking for:

overrideBuildReleaseId Value	result
Empty string	Old behavior looks for last successful build using optional stage and tag filters

Didn't know that I could assign an empty string to overrideBuildReleaseId
It just works as I expected! Maybe you could add this information to the wiki page.

Thanks a lot.

I will push out a documentation update to the marketplace and the WIKI today
