Byteman README -------------- Byteman supports injection of side effects into Java programs for the purpose of tracing and testing application behaviour. Installation ------------ If you have downloaded a binary release then unzip it into a target install directory. This directory contains everything you need to use byteman. You should set environment variable BYTEMAN_HOME so that it points to the target install directory. If you have downloaded a full release then unzip into a target release directory. The release includes a subdirectory called install which contains everything you need to use byteman. You should set environment variable BYTEMAN_HOME so that it points to the install subdirectory. If you execute command 'ant install' in the target release directory then this will rebuild the byteman release from the sources overwriting the original contents of directory install. The install directory contains the following subdirectories bin -- contains Unix scripts to simplify: using Byteman (bmjava.sh); typechecking Byteman rule scripts (bytemancheck.sh); communicating with the Byteman agent listener (bmsubmit.sh); and installing the agent into a running JVM (bminstall.sh). You will need to change the permissions of these files in order to execute them directly from the command line. docs -- contains the Byteman Programmer's guide and license information for Byteman plus the third-party software it uses lib -- contains the Byteman agent and rule engine (byteman.jar); the subset of this code needed to compile/run the submit client (byteman-submit.jar); the subset of this code needed to compile/run the install client (byteman-install.jar). sample/lib -- contains helper code for the sample scripts sample/scripts -- contains example rule scripts showing how to use Byteman contrib -- contains software contributed by other Byteman users Using Byteman ------------- Please consult the Programmer's Guide for details of how Byteman operates, how to write Byteman rule scripts and how to run a Java program with the Byteman agent in place. Take a look at the sample scripts directory to see some examples of how you can use Byteman to trace application and JVM execution or to gather and present statistics detailing the operation of JVM or application code. (n.b. these examples still need extending to show how to use Byteman for fault injection based testing). Copyright --------- See the copyright file in the docs directory for details of the open source license under which this code is released. Note that this code employs the ObjectWeb ASM package to do bytecode manipulation and the JFlex and JavaCUP tokeniser and parser genereators to generate and provide runtime support for the rule parser which are also released under open source licenses.
