The goal of the frysk project is to create an intelligent,
distributed, always-on system monitoring and debugging tool that
allows developers and system administrators to monitor running
processes and threads (including creation and destruction events),
monitor the use of locking primitives, expose deadlocks, gather data
and debug any given process by either choosing it from a list or by
accepting frysk's offer to open a source code or other window
on a process that is in the process of crashing or that has been
misbehaving in certain user-definable ways.
frysk is free software and so is generally and freely
available as both a research and development platform.

Khanna, Teresa Thomas, Thomas Girard, Tim Moore, Tom Tromey, Wu Zhou,
Yao Qi, Yong Zheng, and Zhao Shujing are pleased to announce our first
official release of Frysk, version 0.2.1.
This initial release includes:
- command line utilities:
fauxv - print the auxiliary vector
fcatch - catch and print the stack of a crashing process
fcore - extract a core file from a running process
fdebuginfo - list debug-info requirements of a process
fdebugrpm - install debug-info requirements of a process
ferror - catch and back-trace error calls
fexe - print the executable path
fmaps - print the address map
fstack - print each thread's stack
fstep - single-step a process
ftrace - trace a processes system and (new) library calls
Known limitations: large resident set size; large executable size.
- Prototype command line debugger: fhpd
For single threaded programs, FHPD can: print the value, type, and
location, and modify the value of, arbitrarily located variable
(complex DWARF location expressions); correctly handle very-large
integers (>64-bit) and large floats (80-bit); display in-line
information in back-traces; control processes with the commands
load, core, dump, run, step, break, go, detach, kill, list, focus.
In addition to the command-line utility restrictions, the HPD has
the following known limitations: disassembler missing; limited
type-cast support in expressions; limited multi-thread support.
- Prototype visual debugging and monitoring tool (frysk)
Known limitations: work-flow limited to live processes (examining
core files, or creating processes is possible but very
non-intuitive).
- Prototype test-suite (funit)
Known limitations: some test that are working in-tree fail when
installed.
