ERROR HANDLING FIXES
- use raise_for_status() to pass through response code
- handle exceptions where no response object is passed through
INSTANCE ACTOR
- models.User.objects.create_user function cannot take an ID
- allow instance admins to determine username and email for instance actor in settings.py
These errors in resolve_remote_id aren't really errors, they're
routine problems that we can expect from dealing with the outside world,
like a connection timeout, a server being down, a server being blocked,
et cetera. It's cluttering up the logs and causing unnecessary worry.
- uppercase ISBN before checking it's a number to account for trailing 'x'
- check maybe_isbn for search_identifiers search. Without this we are only searching external connectors, not locally!
ISBNs are always numeric except for when the check digit in ISBN-10s is a ten, indicated with a capital X.
These changes ensure that ISBNs are always upper-case so that a lower-case 'x' is not used when searching.
Additionally some ancient ISBNs have been printed without a leading zero (i.e. they only have 9 characters on the physical book). This change prepends a zero if something looks like an ISBN but only has 9 chars.
The parser was extracting the list of search results from the json
object returned by the search endpoint, and the formatter was converting
an individual json entry into a SearchResult object. This just merged
them into one function, because they are never used separately.
Instead of having individual search functions that make individual
requests, the connectors will always be searched asynchronously
together. The process_seach_response combines the parse and format
functions, which could probably be merged into one over-rideable
function.
The current to-do on this is to remove Inventaire search results that
are below the confidence threshhold after search, which used to happen
in the `search` function.
This is the untest first pass at re-arranging remote search to work in
parallel rather than sequence. It moves a couple functions around
(raise_not_valid_url, for example, needs to be in connector_manager.py
now to avoid circular imports). It adds a function to Connector objects
that generates a search result (either to the isbn endpoint or the free
text endpoint) based on the query, which was previously done as part of
the search.
I also lowered the timeout to 8 seconds by default.
