purgedConfiguration

[Chris Saunders]

I've tested the 1.67 release and have many new info messages following the pattern:

"The configuration '" + configuration + "' was not checked because its code equals another one.",

But can't figure out what the trigger criteria are for the subset of pre-processor symbols in our code that trigger this. Is there any additional documentation?

Thanks!

It's not a problem. You don't need to fix this.

Maybe Cppcheck should write which other configuration matches.

But can't figure out what the trigger criteria are

This message is written if configuration X generates the same preprocessor output as configuration Y. Then Cppcheck only checks either X or Y not both. This saves CPU and gives you the same results.

I see, thanks for the explanation!

Wouldn't it be better to rephrase the message then? Today, after upgrading to Cppcheck 1.68, I also see lots if this messages and they are very confusing.

[Daniel Marjamäki]

Yes it sounds like we need to rephraze it. Any suggestions?

Maybe:

Configuration X generates the same preprocessor output as configuration Y. The results would be the same for these configurations. Therefore Cppcheck will skip configuration Y.

How about a way to turn that particular message off?

I suppressed this specific message in the cppcheck project file by adding this lines

    <suppressions>
        <suppression>purgedConfiguration</suppression>
    </suppressions>

This must be done by hand because the GUI doesn't list this warning in

File > Edit Project File... > Tab "Suppressions" > Button [Add]

It is a bug that it is not listed. Probably in our LIB.

However for your information it is in git head possible to right click a message and click on "Suppress selected id(s)".
