* Add GOPATH to PATH in find-lint.sh.
The user doesn't necessarily have it in PATH.
* Refactor LoginTypePassword and Type to support m.login.token and m.login.sso.
For login token:
* m.login.token will require deleting the token after completeAuth has
generated an access token, so a cleanup function is returned by
Type.Login.
* Allowing different login types will require parsing the /login body
twice: first to extract the "type" and then the type-specific parsing.
Thus, we will have to buffer the request JSON in /login, like
UserInteractive already does.
For SSO:
* NewUserInteractive will have to also use GetAccountByLocalpart. It
makes more sense to just pass a (narrowed-down) accountDB interface
to it than adding more function pointers.
Code quality:
* Passing around (and down-casting) interface{} for login request types
has drawbacks in terms of type-safety, and no inherent benefits. We
always decode JSON anyway. Hence renaming to Type.LoginFromJSON. Code
that directly uses LoginTypePassword with parsed data can still use
Login.
* Removed a TODO for SSO. This is already tracked in #1297.
* httputil.UnmarshalJSON is useful because it returns a JSONResponse.
This change is intended to have no functional changes.
* Support login tokens in User API.
This adds full lifecycle functions for login tokens: create, query, delete.
* Support m.login.token in /login.
* Fixes for PR review.
* Set @matrix-org/dendrite-core as repository code owner
* Return event NID from `StoreEvent`, match PSQL vs SQLite behaviour, tweak backfill persistence (#2071)
