The trace no longer contains the failed execs of execvp() trying various paths. - Add global filter support to trace-cmd read. If the -F filter is placed before any -i file, it will be applied to all files. Otherwise the -F filter will only be applied to the last file specified. - Added new "attach" command that can take a trace.dat file created from the host at the same time a trace.dat file was created on one of its guests, and be able to set the meta data to hook them together like if it was done via trace-cmd agent. This is useful for boot time tracing. Fixes since 3.1.6 - Fix the way filters were applied to trace-cmd report with multiple trace.dat files. - Fixed trace-cmd extract to not extract the top level buffer unless specifically asked to. That is, "trace-cmd extract -B foo" will only extract the data from foo and not the top level buffer. - Fixed record and extract to not destroy specified instances if they were not created by the record or extract. - Add memory (valgrind) testing to utest. - Add meson build support (although it's not the default yet). https://git.kernel.org/pub/scm/utils/trace-cmd/trace-cmd.git/ Enjoy! -- Steve
