Previous to this change, repositories were looked up unfiltered in six different queries, and then filtered using the permissions model, which issued a query per repository found, making search incredibly slow. Instead, we now lookup a chunk of repositories unfiltered and then filter them via a single query to the database. By layering the filtering on top of the lookup, each as queries, we can minimize the number of queries necessary, without (at the same time) using a super expensive join.
Other changes:
- Remove the 5 page pre-lookup on V1 search and simply return that there is one more page available, until there isn't. While technically not correct, it is much more efficient, and no one should be using pagination with V1 search anyway.
- Remove the lookup for repos without entries in the RAC table. Instead, we now add a new RAC entry when the repository is created for *the day before*, with count 0, so that it is immediately searchable
- Remove lookup of results with a matching namespace; these aren't very relevant anyway, and it overly complicates sorting
Adds the missing field on the query_user calls, updates the external auth tests to ensure it is returned properly, and adds new end-to-end tests which call the external auth engines via the *API*, to ensure this doesn't break again
Before this change, external auth such as Keystone would fail if a user without an email address tried to login, even if the email feature was disabled.
It appears the recent migration of the LDAP code and add of a check for the admin username/password being invalid *broke the LDAP password check*, allowing any password to succeed for login. This fixes the problem, add unit tests to verify the fix and add some tests to our other external auth test suite.
A release will be needed immediately along with an announcement
