Description

When I run two almost same copy calls it has very different impact on performance. First (a) is creating correct query on all-content repo. It means it contains filters. If I call second one (b), pulp somehow leave out filters and queries everything in all-content. It fetches all and then call file by file queries. As in my repo is quite a lot of files, apache soon eats all memory (30GB) and crashes. Difference is just in querying more unit types in one call. Of course there is a workaround to split it to more calls, but in first place it is not expected behaviour.

This behaviour is present in 2.3 release, not sure if it is fixed in newer releases.

from pulp_rpm.common.ids import UNIT_KEY_RPM
filters = {'checksum': {'$in': ['abc', 'def', ghi']}, 'checksumtype': 'sha256'}
fields = list(UNIT_KEY_RPM) + ['filename', 'signature']
a = repo_unit_api.copy('all-content', 'test-rpm', type_ids = ['rpm'], filters=filters, fields=fields).response_body.task_id
b = repo_unit_api.copy('all-content', 'test-rpm', type_ids = ['rpm', 'iso'], filters=filters, fields=fields).response_body.task_id
