Best way to stop processing from slaves

ROOT
#1

Hi,
I wonder what would be the recommended way to stop processing from a slave when a given (wrong) condition is found in a selector.

Thanks,

Hi Isidro,

You can call the TSelector::Abort(…) functions inside the TSelector, either to stop processing

    Abort("Stop full processing", kAbortProcess);

or to skip the file

    Abort("Skip this file", kAbortFile);

Hope it helps.

HI Gerri,

Thanks a lot. I think this is what I was looking for. Will this stop all slaves or just the one “aborting”?

Cheers,

Only the one aborting, as it is now. The slave will be gone, but in the PROOF spirit processing continues with the others.
Not sure how difficult wouldbe to add an option to stop the full query if one slave goes.
