Subject: [PATCH v2] perf scripts python: Add Python 3 support to powerpc-hcalls.py

Support both Python 2 and Python 3 in powerpc-hcalls.py.
``print`` is now a function rather than a statement. This should
have no functional change.

The "has_key()" method is deprecated in favor of the "in" operator.
So incorporate those changes here.

Subject: [PATCH v2] perf scripts python: Add Python 3 support to syscall-counts.py

Support both Python 2 and Python 3 in syscall-counts.py. ``print``
is now a function rather than a statement. This should have no
functional change.

Fix lambda syntax error

hum, could you please add some info about testing those changes?
(or even some global into 0/.. patch)

this is working for me on python2:

[root@krava perf]# perf script rec check-perf-trace
^C
[root@krava perf]# perf script -s scripts/python/check-perf-trace.py
trace_begin

unhandled events:


event count

but fails for python3:

Yes I'm seeing the same error with check-perf-trace.py.

I think the issue happens only when we use 'perf script -s path/to/script.py'
instead of 'perf script report script_name':

Ex:

# PERF_EXEC_PATH=`pwd` ./perf.python3 script record stackcollapse
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.263 MB perf.data (497 samples) ]

# PERF_EXEC_PATH=`pwd` ./perf.python3 script report stackcollapse
migration/21 1
migration/41 1
perf 9
rngd 1
sshd 1
swapper 482
xfsaild/sda5 2

# PERF_EXEC_PATH=`pwd` ./perf.python3 script -s scripts/python/stackcollapse.py
Traceback (most recent call last):
File "scripts/python/stackcollapse.py", line 31, in <module>
from perf_trace_context import *
ModuleNotFoundError: No module named 'perf_trace_context'
Error running python script scripts/python/stackcollapse.py

So, it seems, this is not the script issue. Something is wrong when we build perf
with python3?


Here is my test summary on Powerpc Fedora 29:

I'd been simultaneously working on a patch set to fix up Python3.

It's actually already in our Factory and SLE15-SP1 releases as we had a deadline to kill Python2 usage for internal rpms.

I was going to post once I'd fixed the last remaining issue ('import perf' is still failing [test #18]).

I guess "you snooze you lose" :-)

https://build.opensuse.org/package/view_file/devel:tools/perf/perf.changes?expand=1

Anyhow, the fix for the above is: 'add-trace_context-extension-module-to-sys-modules.patch' from above.

Attached below. Verified with PYTHON=python2 and PYTHON=python3

Tony

---------------------------------

In Python3, the result of PyModule_Create (called from
scripts/python/Perf-Trace-Util/Context.c) is not automatically added to
sys.modules. See: https://bugs.python.org/issue4592

Below is the observed behavior without the fix.

pickle is already in Python2.

Is the 'print (x),' [trailing comma] syntax valid for function syntax?

Print "x", in Py2 means suppress the trailing newline.

You need to actually run the scripts (old, new PYTHON=python2, new PYTHON=python3) and compare the output.

This:
print "%-40s %10s\n" % ("comm [pid]/syscalls", "count"),

can be reworked as:
print ("%-40s %10s" % ("comm [pid]/syscalls", "count"))

Again, check the trailing comma usage:

$ echo 'print "abc", ; print "def"' | python2
abc def
$ echo 'print ("abc"), ; print ("def")' | python2
abc def
$ echo 'print ("abc"), ; print ("def")' | python3

They are best handled via conversion to sys.stderr.write() since sys is already imported.

You don't need this unless you're actually requiring functionality that only exists in v3.
For example, you need it to handle the suppress newline functionality such as "end=".

Same feedback as all the other patches applies.

In addition:

$ git annotate tools/perf/scripts/python/netdev-times.py | grep "all_event_list.sort"
359d5106a2ff4 (Koki Sanagi 2010-08-23 18:47:09 +0900 175) all_event_list.sort(lambda a,b :cmp(a[EINFO_IDX_TIME],

I didn't think the above was valid with Python3.

In my version (https://build.opensuse.org/package/view_file/devel:tools/perf/port-failed-syscalls-by-pid-script-to-python3.patch?expand=1)
I reworked it as:

from functools import cmp_to_key
all_event_list.sort(key=cmp_to_key(lambda a,b :a[EINFO_IDX_TIME] < b[EINFO_IDX_TIME]))

Did you test any of these changes with Python3?

If you run 'ldd /usr/bin/perf | grep python' when you've built with PYTHON=python3, what do you see?

$ ldd /usr/bin/perf | grep python
libpython3.6m.so.1.0 => /usr/lib64/libpython3.6m.so.1.0 (0x00007fea66701000)

As I said in a different post, I'd not yet posted my series as I was still trying to fix the failure of the "import perf" testcase (aka tools/perf/python) and (apologies) I'd missed your V1 but maybe I should post them as they've been thoroughly integrated into perf and tested with python2 and python3.

The full patchset is in SLE15-SP1 beta2 which I know IBM has access to. A backport is also in Factory.

Seeteena, I'm than happy to forward my patches via email. Alternatively, as I said in another post, the full series is in SLE15-SP1/beta2 (should apply to tip) which IBM has access to and they've been backported to v4.19 (Factory) at https://build.opensuse.org/package/show/openSUSE:Factory/perf. Everything has been tested against python2 and python3.

Also, in this series there are patches to:
- port tests/attr.py to Python3
- remove shebangs from the .py scripts and change to mode 644 as IMO it makes no sense to explicitly have #!/usr/bin/python since per pep-0394 this refers to version2 and the system may only have python3 installed
- remove the shebang from setup.py since it's explicitly invoked via call to ${PYTHON_WORD}

Also I found in testing that the following fix is also needed. I'm not 100% sure on it and was going to revisit before posting but _PyUnicode_FromStringAndSize() is definitely unsafe to use on attr.

----

Fixes: 66dfdff03d196e51322c6a85c0d8db8bb2bdd655

With Python3. PyUnicode_FromStringAndSize is unsafe to call on attr and will
return NULL. Use _PyBytes_FromStringAndSize (as with raw_buf).

Also, it brings up a question I had. What python versions are expected to be supported with PYTHON=python2?

https://python-future.org/imports.html So importing from future (for end='' support) implies >= 2.6.

The base release of 2.6 was October 2008 so maybe this is fine. Otherwise it may be preferable to use sys.stdout.write which has more consistent semantics (see
tools/perf/scripts/python/compaction-times.py)

Did you mean in Python3? I would agree that using it is better than
importing the semi-hidden _pickle module.

That said, I'll echo the questions about testing. Pickle works in
Python3, but it is fraught with all kinds of bytes/str and encoding
issues; I've found it sufficiently fragile in practice that I really just
try to avoid it. How have you verified that this script works under both
versions of Python?

Thanks,

jon

No. I meant Python2 :)

pickle in Python2 is the python implementation
cPickle in Python2 is the C implementation.

Read: https://docs.python.org/3.1/whatsnew/3.0.html#library-changes
A common pattern in Python 2.x is to have one version of a module implemented in pure Python, with an optional accelerated version implemented as a C extension; for example, pickle and cPickle. This places the burden of importing the accelerated version and falling back on the pure Python version on each user of these modules. In Python 3.0, the accelerated versions are considered implementation details of the pure Python versions. Users should always import the standard version, which attempts to import the accelerated version and falls back to the pure Python version.

I my patchset "import pickle" was sufficient for Python2 and Python3 The question I suppose is whether this script, for Python2, needs the accelerated C implementation. I decided it didn't.

Thanks Tony. added changes to handle the conversion of "print >>

well.  revised patch posted.
