= Proposed Self Contained Change: Erlang 19 = https://fedoraproject.org/wiki/Changes/Erlang_19 Change owner(s): * Peter Lemenkov <lemenkov@xxxxxxxxx> * Fedora Erlang SIG <erlang@xxxxxxxxxxxxxxxxxxxxxxx> * Randy Barlow <rbarlow@xxxxxxxxxxxxxxxxx> * Jeremy Cline <jcline@xxxxxxxxxxxxxxxxx> == Detailed Description == Upgrade Erlang to version 19 which brings a lot of good stuff. Just a few highlights: * A new state machine behavior - gen_statem. * An experimental plugin to mnesia which allows using expernal storage solutions (leveldb, for example) - mnesia_ext. * Cryptographic functions speedups. * Even better dirty NIF schedulers [1]. * Experimental support for Unix Domain Sockets which opens a door for native Journald, systemd-notify, D-Bus implementations. Aside from this, we plan to improve quality of Erlang and related packages. These are shortcomings we want to address: * We should enable so-called dirty NIF scheduler [1] which is still disabled currently. * Every daemon written in Erlang has its own logging solution which doesn't use neither syslog nor Journald. We should start switching them to Journald. * We should add ability to use D-Bus via erlang-dbus library. * Further improve Erlang Packaging Guidelines [2]. == Scope == * Proposal owners: ** Upgrade Erlang to the latest version (19.0.1) [3]. ** We must rebuild every package which requires NIF or Driver version (listed below in the [[#Dependencies|Dependencies]] section) against Erlang 19.x.y. ** Every Erlang daemon's systemd unit must require epmd.socket. ** Consider allowing EPMD implementation switching. Erlang is about choice! ** We need to fill new review request for erlang-ejournald [4] *** We have to fill new review request for erlang-lager_journald_backend [5] ** We need to fill new review request for erlang-dbus [6] ** Add another default directory to look for Erlang *.beam files. ** Upgrade outdated packages: *** Riak [7] **** Riak has has been retired. We have to re-add it back. * Other developers: N/A * Release engineering: N/A * Policies and guidelines: ** We should promote officially Erlang Packaging Guidelines [2].
