Thibaut CHARLES ec30d143cd User registration return M_USER_IN_USE when username is already taken (#372) ... When registering a new user using POST `/_matrix/client/r0/register`, the server was returning a 500 error when user name was already taken. I added a check in `completeRegistration` to verify if the username is available before inserting it, and return a 400 `M_USER_IN_USE` error if there is a conflict, as [defined in matrix-doc](https://matrix.org/speculator/spec/HEAD/client_server/unstable.html#post-matrix-client-r0-register) Signed-off-by: Thibaut CHARLES cromfr@gmail.com		2017-12-19 09:49:42 +00:00
