[erlang-bugs] Cover compiling of .beam files inside .ez archives, is it possible?

[Diego Llarrull]

Good day to everyone,

I'm building a riak-core based application which relies con rebar + gnu 
make to generate deployment nodes (i.e: an embedded erts plus all source 
code and dependencies). Each app is stored in an .ez file inside the 
"lib" folder. No unzipping of the files in a special directory occurs in 
runtime because the code server is able to load .beam files from 
archives (tough experimentally, as stated in 
http://www.erlang.org/doc/man/code.html).

The cover server, instead, can't access such files, which makes it 
impossible to perform cover analysis in runtime (something we require 
because the modules to analyse rely on servers which are spawned on 
demand). My question would be the following:

1) Is it possible to cover compile the binaries at compile-time (i.e., 
before generating the node releases) ?
2) Is there any way to access the .ez files without unzipping them, so 
as to pass a reference to that file to cover:compile_beam() ?

(Note to rebar users: rebar eunit doesn't do the job for me, because it 
performs offline, static, coverage analysis).

Any help would be greatly appreciated.

Thanks in advance
