RPM Support

When one publishes an RPM repository, a number of metadata files are created. These files should be cleaned up at some point. Otherwise, metadata files from various publishes will pile up and consume resources such as disk space and inodes. RPM distributors offer a pair of options to control this behaviour:

• remove_old_repodata defines whether old metadata should be cleaned up at some point.
• remove_old_repodata_threshold defines how old metadata should be before it's cleaned up.

The most aggressive possible combination is {"remove_old_repodata": true, "remove_old_repodata_threshold": 0}. This combination of values should produce the following apparent publish-time behaviour:

# Pseudocode
if remove_old_repodata:
  for metadata_file in metadata_files:
    if age(metadata_file) >= remove_old_repodata_threshold:
      delete(metadata_file)
generate_new_metadata()

However, the Pulp 2 master code that will become Pulp 2.17 produces the following apparent publish-time behaviour:

# Pseudocode
generate_new_metadata()
if remove_old_repodata:
  for metadata_file in metadata_files:
    if age(metadata_file) >= remove_old_repodata_threshold:
      delete(metadata_file)

The underlying cause of the bug could be something else, of course. Notably, setting remove_old_repodata_threshold to 1 fixes the problem. Regardless of the exact reason, the end result is that one can publish an RPM repository that has absolutely no metdata. No repomd.xml, no ...-comps.xml, nothing.

The easiest way to reproduce is to execute a Pulp Smash test: python -m unittest pulp_smash.tests.pulp2.rpm.api_v2.test_republish.RemoveOldRepodataTestCase.test_cleanup_now. To reproduce in a more manual fashion, create an RPM repository with a request like the following, then add content to Pulp and publish the repository:

{'distributors': [{'auto_publish': False,
                   'distributor_config': {'generate_sqlite': True,
                                          'http': True,
                                          'https': True,
                                          'relative_url': '73d25e9e-24d7-4953-98bb-ebe055be3050/',
                                          'remove_old_repodata_threshold': 0},
                   'distributor_id': 'e4cbd2ed-626c-4dc0-acde-7125fef8373e',
                   'distributor_type_id': 'yum_distributor'}],
 'id': '653a3067-1d57-4114-bf5a-49b4fc08e3ff',
 'importer_config': {},
 'importer_type_id': 'yum_importer',
 'notes': {'_repo-type': 'rpm-repo'}}

Here's some logs from a target VM while the aforementioned Pulp Smash test is running. Notice the two "Removed outdated" blocks in the log. This is from the two publishes.
