Fix code for Python3 #11

No description provided.

Could you explain what it is that you're trying to fix? All I see is some style and default args changes.

szymonlipinski · 2020-12-18T17:06:21Z

Sure. I get lots of TypeError: a bytes-like object is required, not 'str' in my code. My first idea was wrong. The current implementation fixes problems in my code. However, the tests for the magicbus are not happy with exactly the same error now.

webknjaz · 2020-12-18T17:08:00Z

@szymonlipinski sounds like you pass the wrong data types when calling magicbus APIs.

@webknjaz I think that the issue is in magicbus.

StdoutLogger and StderrLogger work on top of sys.stdout and sys.stderr, both of them are text mode files, not binary files, thus you can't encode to bytes the output you want to send to them

The issue can be replicated with a very short snippet:

>>> from magicbus.plugins.loggers import StdoutLogger
>>> StdoutLogger(bus=mock.Mock(id=5)).log("hello", 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/amol/wrk/crunch/venv/lib/python3.7/site-packages/magicbus/plugins/loggers.py", line 34, in log
    self.stream.write(complete_msg)
TypeError: write() argument must be str, not bytes

I think that the PR is wrong as it changes too many things (it changes also StreamLogger and FileLogger which instead is ok they work using bytes) but for StdoutLogger and StderrLogger we surely want to change encoding='utf-8' to be encoding=None as the encoding is managed by sys.stdout and sys.stderr themselves.

webknjaz · 2021-01-26T14:53:53Z

Fair enough

szymonlipinski · 2021-02-03T09:50:52Z

It looks like the tests hang on python 2.7 even if I reverted all changes from this PR: https://travis-ci.org/github/cherrypy/magicbus/jobs/757368941

-
+            else:
+                if not isinstance(complete_msg, unicodestr):
+                    complete_msg = complete_msg.decode("utf-8")


I wonder if in this case we might want to add errors="backslashreplace" given that we are mostly guessing utf-8 might be a good choice.

PPS: This can probably just become

if isinstance(complete_msg, unicodestr): encoding = self.encoding or "utf-8" complete_msg = complete_msg.encode(encoding, errors="backslashreplace")

Sorry, I misread the two if branches o_O
You are encoding in one and decoding in the other, my suggestion of squashing the two branches was totally wrong :D

Yea, you're right. I haven't noticed that too :) I have reverted the changes. I think it's fine now.

-                    complete_msg = complete_msg.decode("utf-8")
+                if isinstance(complete_msg, unicodestr):
+                    encoding = self.encoding or "utf-8"
+                    complete_msg = complete_msg.encode(encoding, errors="backslashreplace")


no, I meant, both ifs can be removed :D

if self.encoding is not None: if isinstance(complete_msg, unicodestr): complete_msg = complete_msg.encode(self.encoding) else: if isinstance(complete_msg, unicodestr): encoding = self.encoding or "utf-8" complete_msg = complete_msg.encode(encoding, errors="backslashreplace")

VS

if isinstance(complete_msg, unicodestr): encoding = self.encoding or "utf-8" complete_msg = complete_msg.encode(encoding, errors="backslashreplace")

szymonlipinski · 2021-02-04T14:34:42Z

@webknjaz Hey, could you take a look at the failing test? It failed also when I reverted all the changes made by this PR. It looks like there is some bigger problem somewhere. All the tests pass on my computer for python2 and python3.

magicbus/plugins/loggers.py

webknjaz · 2021-02-11T13:44:51Z

It looks like there is some bigger problem somewhere.

Since it is only happening in CIs and hang on the tests that have TTY in their name, my best guess is that the CIs don't allocate a TTY when running these tests and that's what's causing the problem. I wonder if we could allocate a TTY on our own in such envs...

webknjaz · 2021-02-11T13:47:41Z

magicbus/plugins/loggers.py


            self.stream.write(complete_msg)
            self.stream.flush()


 class StdoutLogger(StreamLogger):

-    def __init__(self, bus, level=None, format=None, encoding='utf-8'):
+    def __init__(self, bus, level=None, format=None, encoding=None):


I don't see how this is related to the problem in question. Could you drop changing the defaults too? It is a behavior change at best (and a public interface change at worst. This does not seem to be fixing bugs.

I think that the default change is actually the fix, otherwise you would have to explicitly pass encoding=None everywhere to make sure this works at all on PY3, as there is no way you can have StdoutLogger work on PY3 if it's encoding.

See

>>> StdoutLogger(mock.Mock(id=5), encoding="utf8").log("HI", level=20) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/amol/wrk/crunch/venv/lib/python3.7/site-packages/magicbus/plugins/loggers.py", line 34, in log self.stream.write(complete_msg) TypeError: write() argument must be str, not bytes

VS

>>> StdoutLogger(mock.Mock(id=5), encoding=None).log("HI", level=20) [b'2021-02-11T15:51:15.308588'] (Bus 5) HI

This looks like a bytes vs unicode py2/3 issue. It's usually better to always have this normalized internally.

I don't personally consider this a string encoding/decoding issue.

The problem is related to the fact that sys.stdout and sys.stderr are text mode files, so you can't send bytes to them at all in PY3. The whole "encoding" option doesn't make much sense for sys.stdout/err in my opinion.
If you want to change the encoding of them you are meant to do sys.stdout.reconfigure(encoding='utf-8')

In PY2 sys.stdout/sys.stderr like most io, were mostly agnostic to what you throw at them and thus tried to do their best with whatever they received, but you were still in theory meant to send unicode to them and get it printed according to sys.stdout.encoding like on PY3.

I think that it was mostly an hack the fact that magicbus allowed you to send bytes to sys.stdout at all totally ignoring what was sys.stdout.encoding

Yeah. Honestly, it'd be great to integrate stdlib logging across all CherryPy projects instead of reinventing the wheel.

webknjaz · 2021-02-11T17:02:54Z

This all looks like a lack of proper text compat functions. See some examples:

A common technique is to either convert most of the stuff to "native" strings or unicode/text with exceptions for passing them as args to certain stdlib interfaces (that require "native" most of the time). In general, it's a good idea to always accept text and "native" from external calls because with bytes we cannot (shouldn't) automatically assume the encoding.

webknjaz · 2021-02-11T19:59:01Z

It looks like there is some bigger problem somewhere.

This is reproducible (gets stuck) for me locally with

$ tox -e py27 -- magicbus/test/test_signals.py::TestSignalHandling::test_SIGHUP_tty

But it passes if I tell pytest not to capture stdin/stdout:

$ tox -e py27 -- magicbus/test/test_signals.py::TestSignalHandling::test_SIGHUP_tty -s

(same with py36)

webknjaz · 2021-02-11T20:08:34Z

Looking further, I now remember that it's #7 that I attempted to fix with #8.

When I add --full-trace, I see that magicbus.plugins.opsys.PIDFile.join() is what enters into an infinite loop:

@szymonlipinski so I hacked that those annoying unrelated failing tests and it should be fine now. Although, I've added an excessive GHA matrix that is flaky at times.

Could you rebase this PR so we could see how it goes?

This reverts commit 28e9064.
