Stefan Benten	492731e31f	server: propagate context to storage layer (#455 ) This change propagates the context of the actual user request through. Additionally it configures the Storj Backend to do in memory buffering instead of relying on temporary files in /tmp/ folders. Fixes #448	2021-12-26 17:17:28 +01:00
Stefan Benten	f062af9fc5	server/handlers.go,storage.go: smaller fixes (#452 ) This change moves a couple of defers in order to prevent them from not being executed since we have returned in error cases early. It also fixes a couple of smaller linting issues, like error messages not starting with a capital letter and variable name collisions with imported packages.	2021-12-26 14:37:22 +01:00
