Split GUI from core about xprof HOT 4 CLOSED

Building and packaging investigation (ongoing)

• both rebar3 and mix support umbrella projects where there are multiple OTP applications under apps/ dir within the same repo
• it is possible to create multiple hex packages, one from each app
• it is also possible to include "anything" in a hex package with files setting. (A list of files and directories to include in the package.) So theoretically even multiple apps can be included
• it is possible to build multiple releases from an umbrella project which include different set of apps. (However this is not too relevant as xprof is a library app which is mostly to be included in the users release. There is only one standalone release candidate: xprof_gui)

Open question:

• if a user would like to depend on the git repo and not a hex package, how to do that?
  rebar3 by default does not really like an umbrella project as dependency
  (Dependency failure: Application xprof_umbrella not found at the top level of directory)

target release already contains conflicting version of cowboy

We have this problem when we try to profile Zotonic 1.x (which relies on Cowboy 2) with XProf.

• if a user would like to depend on the git repo and not a hex package, how to do that?

Would this be necessary? What about two apps: xprof_tracer and xprof_gui? The umbrella repository would then simply be the combination of the two, which each of them independently published to Hex.

thanks for your input, David.

I pushed branch cowboy_2.0 based on latest XProf release. It shouldn't be merged to master but it can serve as a temporary solution for those who would like to use XProf in a project with cowboy 2.0, until this task is properly addressed.

XProf is now split into 3 applications #101 and published separately to hex.pm #129 (since 2.0.0-rc.0)
