auth: fix nil reference in auth method check
Add @anoninternal support code
This is a slightly better approach to the previous commit.
auth: implement internal anonymous authentication
This is used for meta.sr.ht's GraphQL user registration resolver, which
needs to run prior to the user's information being added to the database.
Fix json struct tag
Found via `go vet`:
auth/middleware.go:259:2: struct field tag `json:"oauth_client_id",omit-empty` not compatible with reflect.StructTag.Get: key:"value" pairs not separated by spaces
Remove %e formatting verbs
%e is not valid for formatting error values:
> %e scientific notation, e.g. -1.234456e+78
Instead, use %w when using fmt.Errorf (for error wrapping) and
%v when using log.Printf (%w is not valid in that context).
auth: improve error response format
This maps more closely onto what normal GQL errors look like.
auth: force webhooks to read-only
auth: harden grants structure
This replaces the Access map with a data type whose default value does
not grant any permissions, so that it's more difficult to create an
insecure auth context by mistake.
webhooks: expand auth configuration
The purpose of this change is to enable internal webhooks to be
configured in GQL webhook tables. A webhook subscription now includes
the auth method field which is appropriate, which is limited to either
OAUTH2 or INTERNAL. In the former case, the previous set of fields will
be valid, and in the latter case, the NodeID field will be valid. This
will allow us to register webhook subscriptions for internal use.
auth: fix /query/api-meta.json route
This route does not need authentication.
webhooks: initial prototype for GQL-native webhooks
auth: s/OAuth2Token/BearerToken/g
This also makes some tweaks to the organization of the crypto module to
make it easier for us to add more keys in the future, which will be
necessary for the internal token redesign.
auth: allow /query/metrics w/o authentication
auth: fix user type on database insert
auth: authenticate all requests under /query
Various bug fixes per pages.sr.ht
crypto: harden API surface
Make it explicit that expiration is not being tested with Decrypt, and
test that the expiration is meaningful with DecryptWithExpiration.
Fetch user PGP key for meta.sr.ht
Correct TODO for context which is invariant
