478332 - Expose profiler information in shell

Status: RESOLVED WONTFIX

(Tamarin Graveyard :: Profiler, enhancement)

Description

[Jeff Dyer]

The player uses a "PreloadSwf" to install Flex Builder "profiler agent" swf that uses the flash.sampler.* API's to serialize profile information to a socket.   avmshell doesn't have anything.    Basic thoughts:

1) have a command line argument -Dprofile to turn on profiling (basically means calling AvmCore::sampler()->startSampling()) before running any script
2) write a profiler.as script that uses getSamples and present some nice formatted data
3) if -Dprofile is specified load and run profiler.abc after running the users script after calling stopSampling
4) extra credit: compile profile.abc into avmshell using asc -builtin (new precedent, builtin w/o natives, might cause problems)

I attached Flex builder' ProfilerAgent.as as a guide, note that the player doesn't call start/stop sampling so the agent does that.

The sampling API's are available but they are actionscript, if more of the shell was written in actionscript like TT it would be trivial to add a -profile flag to turn this on.  I'd like to see it built into the shell rather than be a separate abc.

Tamarin is a dead project now. Mass WONTFIX.
