remctl 3.4

remctl is the client/server protocol that we use for basically all our middleware connections at Stanford. It uses Kerberos GSS-API for authentication and privacy and is designed to be as simple as possible, just running a command on the server with the provided arguments. We've found this design to be extremely effective and a significant improvement over trying to put web servers everywhere to use something like REST.

The primary feature in this release is a new Net::Remctl::Backend Perl module that automates a lot of the work of creating remctl backend scripts written in Perl. Over the years, we've developed a lot of conventions for things like help output and command-line processing, and this rolls those conventions into a module that handles a lot of the work of formatting help output and handling command dispatch. This is just the first cut, but it already supports argument validation, handling standard input, formatting help output, and handling per-option command-line flags. Later versions will feature better integration with Kerberos and hopefully better integration into the new remctl help and summary features.

Also in this release are new C APIs contributed by Jeffrey Hutzelman that allow one to start a remctl connection over an existing sockaddr, a list of struct addrinfo results, or an open socket.

In the bug fix department, this release removes all the prototypes from Net::Remctl functions following current Perl best practices (prototypes cause weird context issues and behave in surprising ways), and rejects the empty command to remctl_command rather than trying to malloc 0 bytes.

You can get the latest version from the remctl distribution page.
