Allow the script generated by "perf script -g <language>" to be a file
path and the language determined by the file extension.
This is useful in testing so that the generated script file can be
written to a test directory.
Committer testing:
$ perf record ls a.a
ls: cannot access 'a.a': No such file or directory
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.003 MB perf.data (7 samples) ]
$ perf script -g python
generated Python script: perf-script.py
$ perf script -g myscript.py
generated Python script: myscript.py
$ diff -u perf-script.py myscript.py
$ tail myscript.py
def trace_unhandled(event_name, context, event_fields_dict, perf_sample_dict):
print(get_dict_as_string(event_fields_dict))
print('Sample: {'+get_dict_as_string(perf_sample_dict['sample'], ', ')+'}')
def print_header(event_name, cpu, secs, nsecs, pid, comm):
print("%-20s %5u %05u.%09u %8u %-20s " % \
(event_name, cpu, secs, nsecs, pid, comm), end="")
def get_dict_as_string(a_dict, delimiter=' '):
return delimiter.join(['%s=%s'%(k,str(v))for k,v in sorted(a_dict.items())])
