Hi there, If you remember from quite a while ago, I proposed some changes to the attach functionality to make it quite a bit better:
http://thread.gmane.org/gmane.linux.kernel.containers.lxc.devel/3429 A few initial patches were already applied back then, some others I wanted to redo with the result of some discussion in mind. I did actually do all the heavy lifting back then immediately after the discussion, but then other things got in the way of me polishing the patches and making them ready for release. I have now actually done that and will post the patches to the mailing list. They consist of a rewrite of the attach functionality that increases flexibility but at the same time reduces complexity a bit. Also, full C and Python API support is now available. (Since I don't personally use Lua, I leave adding Lua support to other people more knowledgeable in that area. But it should be relatively straight-forward.) I'd be in favor of having those things in 1.0alpha1, especially since the general implementation idea itself had been approved way back then and I just didn't have time to send these patches earlier. There are some minor things that are still on my TODO list that could probably come after 1.0alpha1: - unify environment variable treatment within execute and attach; we decided even longer ago that for 1.0 attach should clear the environment by default (for compatibility we decided in 0.9 that it would keep it); also execute should probably rely on the same functions attach uses to allow the user to force it to keep the environment and/or specific variables - signal handling in attach: while attaching, for the thread that tries to start the attached process, block all signals save SIGCHLD until attach has completed and the attached process is actually running, then reset the thread's signal mask. -- Christian ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
