RPM Support

**** Troubleshooting Steps **

**** adding a rpdb on the process_main() of PublishRpmStep we can see the following:

/usr/lib/python2.7/site-packages/pulp_rpm/plugins/distributors/yum/publish.py
-----
  482     def process_main(self, item=None):
  483         """
  484         Link the unit to the content directory and the package_dir
  485 
  486         :param item: The item to process or none if this get_iterator is not defined
  487         :type item: pulp_rpm.plugins.db.models.RPM or pulp_rpm.plugins.db.models.SRPM
  488         """
  489         import rpdb; rpdb.set_trace()
  490         unit = item
  491         source_path = unit._storage_path
  492         relative_path = file_utils.make_packages_relative_path(unit.filename)
  493         destination_path = os.path.join(self.get_working_dir(), relative_path)
  494         plugin_misc.create_symlink(source_path, destination_path)
  495         for package_dir in self.dist_step.package_dirs:
  496             destination_path = os.path.join(package_dir, unit.filename)
  497             plugin_misc.create_symlink(source_path, destination_path)
  498 
  499         for context in (self.file_lists_context, self.other_context, self.primary_context):
  500             context.add_unit_metadata(unit)

Running the code we will have:

**** source_path is pointing correct to the content unit file

    (Pdb) source_path 
    u'/var/lib/pulp/content/units/rpm/40/a9bfdeba456727e151d53adc41cc688d4360a71dde8e73a18150d72d6d300b/tigervnc-license-1.8.0-13.el7.noarch.rpm'

**** relative_path has the correct and expected location from that file

    (Pdb) relative_path
    u'Packages/t/tigervnc-license-1.8.0-13.el7.noarch.rpm'

**** destination_path has the temporary worker location

    (Pdb) destination_path
    u'/var/cache/pulp/reserved_resource_worker-2@pulp.mmello.local/c8c776b9-71a5-418c-8b20-bdcb2aa55016/Packages/t/tigervnc-license-1.8.0-13.el7.noarch.rpm'

The looking at the temporary worker directory, nothing was placed yet in the Packages directory:

        [root@pulp c8c776b9-71a5-418c-8b20-bdcb2aa55016]# tree

When the `plugin_misc.create_symlink(source_path, destination_path)` is called, the symlink is created as expected:

        Every 1.0s: tree Packages/                                                                                                                                                                         Thu Mar 14 00:10:57 2019

        Packages/
        └── t
            └── tigervnc-license-1.8.0-13.el7.noarch.rpm -> /var/lib/pulp/content/units/rpm/40/a9bfdeba456727e151d53adc41cc688d4360a71dde8e73a18150d72d6d300b/tigervnc-license-1.8.0-13.el7.noarch.rpm

       1 directory, 1 file

At this point, a loop is performed which will be calling again the create_symlink method for all members from `self.dist_step.package_dirs`. This case, that list thas the following:

        (Pdb) self.dist_step.package_dirs 
        [u'/var/cache/pulp/reserved_resource_worker-2@pulp.mmello.local/c8c776b9-71a5-418c-8b20-bdcb2aa55016/Packages']

    ** So running the loop we have:

        495              for package_dir in self.dist_step.package_dirs:
        496  ->                destination_path = os.path.join(package_dir, unit.filename)
        497                  plugin_misc.create_symlink(source_path, destination_path)

Then on this loop is where the problem happens:

        (Pdb) destination_path
        u'/var/cache/pulp/reserved_resource_worker-2@pulp.mmello.local/c8c776b9-71a5-418c-8b20-bdcb2aa55016/Packages/tigervnc-license-1.8.0-13.el7.noarch.rpm'

        Every 1.0s: tree Packages/                                                                                                                                                                         Thu Mar 14 00:14:29 2019

        1 directory, 2 files

To a quick test, commenting out the for loop on the self.dist_step.package_dirs, the repository got created corretly.

        [root@pulp ~]# pulp-admin  rpm repo  publish run  --repo-id centos-7-base --force-full

Then the repo got published as expected:

Basically the fix we need to validate if that loop is still necessary or to add a method to verify if the file already exists to avoid duplication.
