[HTCondor-users] Dataflow job skips when executable is updated

[Marco van Zwetselaar <zwets@xxxxxxxxxx>]

Dear all,

I just discovered the massively useful "skip_if_dataflow" submit option 
(how did I miss this before?). Its docs say that the job will be skipped 
only if its outputs are newer than either its inputs or executable. This 
works correctly for the inputs, but when I touch the executable the job 
still skips.

A related one for the wish list: when "transfer_output_files = dir", 
then if directory 'dir' already exists, its timestamp isn't updated when 
Condor transfers it back (at least on my file system), hence the job 
will never be skipped.

I'm aware that directory timestamp updates depend on file system and 
transfer mechanism, but for dataflow jobs it would be desirable if 
Condor explicitly touched the items in transfer_output_files upon return.

Cheers
Marco
