I'm going to speak at the next Moscow Golang User Group this November and will describe some of Fedora Golang SIG plans. Here are the slides (in Elglish and in Russian): * http://peter.fedorapeople.org/presentations/Moscow%20Golang%20Users%20Meetup%202013-11-20%20Fedora%20and%20Golang.en.pdf * http://peter.fedorapeople.org/presentations/Moscow%20Golang%20Users%20Meetup%202013-11-20%20Fedora%20and%20Golang.pdf I won't talk about Docker (my fellow golangers from Yandex will do), and won't tell anything about etcd (we still don't decide what to do with it). Instead I'll describe my effords to fix long-standing issue with systemd and multiple Erlang nodes running in parallel. I did few attempts to fix that issue with different success, and finally switched over to golang-powered solution which fixes it (and makes a room for further improvements). This will have an interesting consequence for the secondary arches, such as s390/s390x and PowerPC. In the future all Erlang services in Fedora, namely CouchDB, Ejabberd, RabbitMQ, Riak, will *want* service written in golang (I wouldn't use word "*require*" here). Since golang is available only for x86/x86_64 and ARM, this could be an annoyance. Technically it will still be possible to run Erlang daemons on the secondary arches, but it will require some painful manual intervention, and lead to inevitable race conditions. Beware! Also I hope we'll see some progress on porting Golang on these achitectures.Is there a strict dependency on golang or just on go? Because "GCC 4.8.2 provides a complete implementation of the Go 1.1.2 release." citing from gcc 4.8.2 release notes and we build gccgo on all our secondary arches.
gccgo will compile on any arch it is available, while the golang compiler has a more limited scope. So far the golang libraries that are packaged are source only, so anyone wanting to build with gccgo, need only set up their compile flags to -I the directories of the libraries needed. This is left as somewhat of an exercise for those interested. Since some projects will have tuned their resulting executable/binary builds to using the golang compiler instead of the gccgo. Take care, vb
