Is it possible to prevent DUCC from publishing?

Publisher / Stratum 0

Hi,

weird question. Would it be possible to have DUCC just to create the new content, place it in the right directory for that repo, but not run “cvmfs_server publish”?
Idea is to be able to run DUCC on a separate host, and issuing the publishing in a separate asynchronous process.

Thanks,
Jose

Hi Jose,

It would require changing the DUCC sources. But you might be able to do this with a workaround. DUCC simply calls cvmfs_server ... so you could provide an executable (script) with that name that does nothing. At least for experimenting.

Cheers,

Hmm, yeah, that should work :slight_smile:

Hmm. Thinking twice, I guess it wouldn’t be as simple as having a fake cvmfs_server executable that does nothing. I assume DUCC also calls “cvmfs_server transaction”, right?
So the script should only ignore “cvmfs_server publish”, for example. However, that would leave the transaction open until the content is published… I can foresee a lot of problems with that :slight_smile:

Thanks anyways.
Cheers,
Jose
