Just use it as + prefix for your usual command line and it will profile + mutexes used in all child processes. Example: + + mutrace gedit + + matrace traces memory allocation operations in realtime + threads for you. It is of no use in applications that do not + make use of realtime scheduling. Example: + + matrace myrealtimetool + + Both tools understand a --debug-info switch in which case the + backtraces generated will include debugging information such as + line numbers and source file names. This is not enabled by + default since generating those traces is not always safe in + situations where locks are taken or memory allocated as we do + it here. YMMV. + + mutrace cannot be used to profile glibc-internal mutexes. + LICENSE: LGPLv3+ + Exception: + + backtrace-symbols.c is GPLv2+. Which probably means that using + the --debug-info switch for mutrace and matrace might not be + legally safe for non-GPL-compatible applications. However, + since that module is independantly built into a seperate .so + it should still be safe using the profilers without this + switch on such software. + AUTHORS: Lennart Poettering |
