O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH 1/1] trace: update qemu-trace-stap to Python 3

Bugzilla: 1787395

|
|
qemu-trace-stap does not support Python 3 yet:
|
||
|
|
|
||
|
|
$ scripts/qemu-trace-stap list path/to/qemu-system-x86_64
|
||
|
|
Traceback (most recent call last):
|
||
|
|
File "scripts/qemu-trace-stap", line 175, in <module>
|
||
|
|
main()
|
||
|
|
File "scripts/qemu-trace-stap", line 171, in main
|
||
|
|
args.func(args)
|
||
|
|
File "scripts/qemu-trace-stap", line 118, in cmd_list
|
||
|
|
print_probes(args.verbose, "*")
|
||
|
|
File "scripts/qemu-trace-stap", line 114, in print_probes
|
||
|
|
if line.startswith(prefix):
|
||
|
|
TypeError: startswith first arg must be bytes or a tuple of bytes, not str
|
||
|
|
|
||
|
|
Now that QEMU requires Python 3.5 or later we can switch to pure Python
|
||
|
|
3. Use Popen()'s universal_newlines=True argument to treat stdout as
|
||
|
|
text instead of binary.
|
||
|
|
|
||
|
|
Fixes: 62dd1048c0bd ("trace: add ability to do simple printf logging via systemtap")
