substitute: Rework connection error handling.prepare-to-move-guix-scripts-substitute-code
This is part of trying to reduce the interdependency of code within the substitute module. This commit addresses some of the error handling that was performed through open-connection-for-uri/maybe. The new approach is to use call-with-connection-error-handling, and wrap calls to http-multiple-get and http-fetch with that procedure, which takes care of handling connection errors. I think this is even slightly more rigerous than the previous setup, because this approach handles connection errors that occur when http-multiple-get reconnects to a host. * guix/scripts/substitute.scm (open-connection-for-uri/maybe): Transform in to call-with-connection-error-handling. (fetch-narinfos): Use call-with-connection-error-handling. (process-query): Replace open-connection-for-uri/maybe with open-connection-for-uri/cached. (open-connection-for-uri/cached): Set a default timeout, matching the behaviour in open-connection-for-uri/maybe. (process-substitution): Use call-with-connection-error-handling.
