Bug 1083637

My ultimate goal is to also have the erlang package buildable or usable without wxGTK, since it's rather silly to have rabbitmq-server require X and/or OpenGL.

(Obviously comment #1 is not the subject of this bugzilla :) )

*** This bug has been marked as a duplicate of bug 784693 ***

There are two separate optimizations - one is for erlang, which looks like bug 784693 - the other is for rabbitmq-server's .spec file - which does -not- need to include the erlang environment metapackage as it does now.

For example, to run rabbitmq-server, there's no need for the debugger, observer, the release tool, etc. - all of which are pulled in as part of the erlang metapackage.

I'll attach a specfile patch.

Yes, indeed. These are two separate issues.

The patch in comment 5 looks reasonable.  Peter what do you think
about [me or you] adding this?  So far I've only made a few quite
conservative changes to the rabbitmq-server package; this is a bit
larger.

Looks good to me.

The package is quite large and contains plugins which are currently cannot be processed by my own poor-man dependency generator properly. However if considering only core functionality it could be trimmed down even more. Here is my final list of RabbitMQ dependencies:

Requires: erlang-erts%{?_isa}
Requires: erlang-kernel%{?_isa}
Requires: erlang-mnesia%{?_isa}
Requires: erlang-os_mon%{?_isa}
Requires: erlang-public_key%{?_isa}
Requires: erlang-sasl%{?_isa}
Requires: erlang-ssl%{?_isa}
Requires: erlang-stdlib%{?_isa}
Requires: erlang-tools%{?_isa}
Requires: erlang-xmerl%{?_isa}

Note that I added "Requires: erlang-tools". Not sure if we need to add %{?_isa} since the package is noarch.

The following dependencies can be removed since my script failed to recognize dependency on them:

Requires: erlang-inets >= %{erlang_minver}
Requires: erlang-asn1 >= %{erlang_minver}
Requires: erlang-snmp >= %{erlang_minver}
Requires: erlang-otp_mibs >= %{erlang_minver}
Requires: erlang-crypto >= %{erlang_minver}
Requires: erlang-runtime_tools >= %{erlang_minver}

There could be a possibility that some of the plugins depends on them though.

Rich, please go on with the changes - I'm not an active RabbitMQ user these days (however I'll be back in a couple of months - my next project will rely on it) so I can't maintain it properly right now.

So, I tried this in my specfile:

  Requires: erlang-mnesia >= %{erlang_minver}
  Requires: erlang-erts >= %{erlang_minver}
  Requires: erlang-xmerl >= %{erlang_minver}
  Requires: erlang-stdlib >= %{erlang_minver}
  Requires: erlang-public_key >= %{erlang_minver}
  Requires: erlang-ssl >= %{erlang_minver}
  Requires: erlang-kernel >= %{erlang_minver}
  Requires: erlang-sasl >= %{erlang_minver}
  Requires: erlang-os_mon >= %{erlang_minver}
  Requires: erlang-tools >= %{erlang_minver}

I turned on SSL and erased runtime_tools (and tools) and things still work. Forcefully erasing some of the others (for example inets) caused rabbitmq-server to fail on startup:

Error description:
   {error,{"no such file or directory","inets.app"}}

You were right about runtime_tools, it's not needed really.

erlang-snmp-R16B-03.2min.2.el7.x86_64
erlang-asn1-R16B-03.2min.2.el7.x86_64
erlang-inets-R16B-03.2min.2.el7.x86_64
erlang-crypto-R16B-03.2min.2.el7.x86_64
erlang-kernel-R16B-03.2min.2.el7.x86_64
erlang-mnesia-R16B-03.2min.2.el7.x86_64
erlang-otp_mibs-R16B-03.2min.2.el7.x86_64
erlang-ssl-R16B-03.2min.2.el7.x86_64
erlang-public_key-R16B-03.2min.2.el7.x86_64
erlang-stdlib-R16B-03.2min.2.el7.x86_64
erlang-os_mon-R16B-03.2min.2.el7.x86_64
erlang-xmerl-R16B-03.2min.2.el7.x86_64
erlang-erts-R16B-03.2min.2.el7.x86_64
erlang-sasl-R16B-03.2min.2.el7.x86_64

Apart from the packages that require wx, a few extraneous packages get pulled in (that is, they are not required for rabbitmq to run):

  erlang-syntax_tools
  erlang-compiler
  erlang-hipe
  erlang-runtime_tools
  erlang-tools

This should be fine.  This is a big improvement over the previous requirement of the 'erlang' meta package.  Once wx is optional (looks like F21), this will be a -huge- improvement!
