Description Neal Gompa 2015-08-13 02:09:11 UTC 
Description of problem:
When using createrepo_c to create repodata that is xz-compressed, it goes ahead and creates gz compressed XML metadata anyway. If I am creating SQLite data too, that data is compressed the way I want it to be, but the XML data is not.

Version-Release number of selected component (if applicable):
createrepo_c-0.9.0-3.fc22

How reproducible:
Always

Steps to Reproduce:
1. Create a folder with some RPMs
2. Run one of the following:
   * createrepo_c --no-database --compress-type=xz <path/to/folder>
   * createrepo_c --database --compress-type=xz <path/to/folder>
   * createrepo_c --no-database --xz <path/to/folder>
   * createrepo_c --database --xz <path/to/folder>

Actual results:
The repodata subfolder contains gz-compressed XML data.

Expected results:
The repodata subfolder contains xz-compressed XML data.

Hi Neal,
this is because of compatibility with createrepo.
I don't like it either, but createrepo does exactly the same thing and because createrepo_c is supposed to be drop-in replacement and thus preserve such illogical behaviour.
Maybe I could add some kind of new command line option or something.
Feel free to open an RFE with ideal of how you would like to see this behave.
