Tasks

• Create common guidelines for erlang-related applications and libraries
• Ensure that all packages are built with +debug_info (slightly increase the size of beam-files, but won't hurt performance at all)
• Allow parallel installation of packages (similar to kernel)
• Retire compat-erlang in Rawhide. Would it be better to update it to R12 or R13?
• Provide pre-built plt images
• Narrow Build Requires - only list packages which are required for building and not the whole erlang stack.
• Remove "soft" dependencies. Some package dependencies are not strictly required - application tries to "dlopen" it (it starts to use it only in case of success; in case of failure it fallbacks to some default scenario). Notable one is a debugger which tries to download GUI interface and fallbacks to cli in case of failure.
• Fix installation of jinterface - it doesn't use %{_javadir} for storing jar-file now.
• All man-pages should be marked as docs. Consider also installing them to system-default paths (very likely will produce a conflicts and namespace clashes).
• pgsql needs patching for R11B due to missing lists:keymember/3 function. Seems to be a very simple task.

1. ↑ No ets:delete/2, ets:insert/2, ets:lookup/2, ets:match_object/2, ets:new/2 and ets:update_counter/3 functions in R11B.
2. ↑ No erlang:function_exported/3, lists:keysearch/3 and lists:member/2 functions available in R11B
3. ↑ No lists:keymember/3, lists:keysearch/3 and string:to_lower/1 functions available in R11B
4. ↑ No public_key module and base64:decode/1, base64:encode_to_string/1, httpc:request/4, re:split/3 and string:to_lower/1 functions available in R11B

6. ↑ No erlang:get_stacktrace/0, erlang:list_to_existing_atom/1, erlang:make_fun/3, lists:keysearch/3 and lists:member/2 functions available in R11B. It seems to be a doable task.

Potential packages

• erlyweb
• Yxa
• erlang-mysql-driver - A native Erlang MySQL client library. One of the runtime dependencies for ejabberd. Please, not that there are two forks - one from P1 and another one from Yariv Sadan. All these three projects are based on the original work by Magnus Ahltorp.
• Jungerl is also contains some very interesting libraries and applications, however not all of them are in good shape.
• User contributions page at trapexit contains some handy user-submitted utilities.
• Nitrogen Web Framework.
• egssapi - Erlang GSSAPI and SPNEGO API (one of the runtime requirements for Yaws).
• eldap - Erlang LDAP API. A patched copy is bundled with ejabberd.
• Riak - a Dynamo-inspired key/value store.

Rejected packages

• Jabberlang - a client Jabber library for Erlang. Obsoleted by exmpp
• erlmedia - Erlang library for parsing different media formats. One of the requirements for erlyvideo. Abandoned by upstream authors.
• erlang-rtmp - Erlang RTMP library. One of the requirements for erlyvideo. Abandoned by upstream authors.
• erlang-fd_server. Similar functionality (binding to privileged ports) may be obtained with kernel > 2.6.24 with capabilities.
