[issue38216] Fix for issue30458 (HTTP Header Injection) prevents crafting invalid requests

[Gregory P. Smith]

Gregory P. Smith  added the comment:

I'd imagine an equivalent of the 3.6 PR would work for 3.5.

Someone should look at how to do similar in 2.7 _if_ the project(s) that 
complained about the problem rely on such behavior in their last 2.7 compatible 
releases.

So, following this recent flurry of activity, all that remains are to sort out 
2.7 and 3.5.  3.5.8 is still in a holding pattern; at this point I think I'm 
going to insert another RC, so I can add the new version of expat.

Will a makes-everyone-happy PR appear for 3.5 soon?

[issue38006] Crash in remove() weak reference callback of weakref.WeakValueDictionary at Python exit

[Tim Peters]

Tim Peters  added the comment:

> call_func and remove are part of a reference cycle. A forced garbage
> collection breaks the cycle and removes the two objects, but they are
> not removed in the expected order:
>
> * first: call_func
> * then: remove
>
> The crash requires to destroy the objects in the reverse order

Victor, I'm not sure what you had in mind there, so please flesh it out if the 
following isn't clear?

In any case "like" the one you constructed, __del__  will always run first, 
with everything needed wholly intact.

Because tp_clear can leave an object in a useless (or worse) state, gc runs all 
finalizers and all weakref callbacks before tp_clear is run on anything.  
tp_clear is used only in delete_garbage, which is the last non-trivial thing gc 
does.  Before then, clears and deallocations happen only as side effects of 
refcounting semantics while running finalizers and callbacks.  So refcount 
precedence order is respected, and nothing will get torn down before its 
refcount hits 0.

At the time gc first calls tp_clear, the intent is that no non-trivial code 
will run again - just tp_clear implementations applying Py_CLEAR to objects' 
members, and deallocations happening as refcounts fall to 0.  No finalizers, no 
callbacks, none, ever ;-)

So what I saw your program doing wasn't just an accident relying on the order 
the objects happened to appear in the list.  Regardless of that order, gc 
forces __del__ to run before tp_clear is applied to anything, and the call_func 
instance is wholly intact when its __del__ runs.

[issue38312] curses: add `set_tabsize` and `set_escdelay`

[Ammar Askar]

Ammar Askar  added the comment:

> I'd like to help with this, but I don't even know where to start with 
> argumentclinic -- any points would be greatly appreciated

Are you asking about argumentclinic in general or something specific to this 
bug? If it's something specific feel free to ignore the following:

You can find a basic tutorial on argumentclinic here 
https://docs.python.org/3/howto/clinic.html#basic-concepts-and-usage

Essentially, you'll be adding something along these lines into _cursesmodule.c

/*[clinic input]
_curses.set_escdelay
size: int
bla bla description for size.
/

One line description.

Extended description. Spanning over
multiple lines.
[clinic start generated code]*/

after which you can run `python3 Tools/clinic/clinic.py _cursesmodule.c` which 
will update the file and place the stub for the method in there.

[issue38296] unittest expectedFailure does not differentiate errors from failures

[Kit Yan Choi]

Kit Yan Choi  added the comment:

I think Python does differentiate "test error" and "test failure" such that a 
test outcome state can be one of these: success, failure, error, skipped. One 
could refine these to six: expected success, unexpected success, expected 
failure, unexpected failure, error, skipped.


For example, in the documentation for failureException:

* failureException: determines which exception will be raised when
the instance's assertion methods fail; test methods raising this
exception will be deemed to have 'failed' rather than 'errored'.


Another evidence: unittest.runner.TextTestResult, there are methods called 
"addSuccess", "addError", "addFailure", "addSkip", "addExpectedFailure" and 
"addUnexpectedSuccess".


For example, this test outcome is marked as "FAILED":

def test(self):
x = 1
y = 2
self.assertEqual(x + y, 4)


==
FAIL: test (test_main.T)
--
Traceback (most recent call last):
  File "test_main.py", line 9, in test
self.assertEqual(x + y, 4)
AssertionError: 3 != 4


But the test outcome for this test is "ERROR":

def test(self):
x = 1
y = 2 + z  # NameError  
self.assertEqual(x + y, 4)


==
ERROR: test (test_main.T)
--
Traceback (most recent call last):
  File "test_main.py", line 8, in test
y = 2 + z  # NameError
NameError: global name 'z' is not defined


The issue here being "expectedFailure" converting "error" to "success", which 
is not expected, and is causing decorated tests to become unmaintained. While 
the rest of unittest differentiates "error" and "failure", expectedFailure does 
not. This is either a bug in the behaviour of expectedFailure, or a bug in the 
documentation for not being clear on the fact that unexpected error will be 
considered as expected failure (which I think is wrong).

[issue38310] Opcode predictions for asserts, class definitions, and some calls.

[Brandt Bucher]

New submission from Brandt Bucher :

This patch adds four new opcode predictions:

BUILD_MAP_UNPACK_WITH_CALL -> CALL_FUNCTION_EX:
 - Emitted whenever more than one map of **kwargs is unpacked into a call.
 - Pair *always* occurs together.

LOAD_BUILD_CLASS -> LOAD_CONST:
 - Emitted whenever a class is defined *without* the use of cell vars.
 - Occurs ~93% of the time, in my analysis.

LOAD_BUILD_CLASS -> LOAD_CLOSURE:
 - Emitted whenever a class is defined *with* the use of cell vars.
 - Occurs the other ~7% of the time

LOAD_ASSERTION_ERROR -> RAISE_VARARGS:
 - Emitted whenever the one-argument form of "assert" is used.
 - Occurs ~91% of the time.

[issue38309] Avoid creating duplicate PATH entries with the macOS installer

[Raymond Hettinger]

New submission from Raymond Hettinger :

The macOS installer updates .bash_profile to add the current python version to 
the PATH.

The problem is that it doesn't check to see if that work has already been done 
in a previous installation.  So, as a person install successive beta releases, 
release candidates, a final release, and then maintenance releases, the PATH 
variable grows and grows.

As it stands now, a manual edit is required every after every update/upgrade.

[issue38296] unittest expectedFailure does not differentiate errors from failures

[Terry J. Reedy]

Terry J. Reedy  added the comment:

A test either passes or fails.  Like a not operator, the expectedFailure 
decorator inverts the result.

https://docs.python.org/3/library/unittest.html#unittest.expectedFailure
@unittest.expectedFailure
Mark the test as an expected failure. If the test fails it will be 
considered a success. If the test passes, it will be considered a failure.

By itself, your 'test' method fails.  Decorated, it should and does pass.

As you suggested, using expectedFailure is a blunt instrument that can be 
misleading if not used carefully and not reviewed when editing the module 
tested.  It is only used 7 times in test_xyz.py modules in the lib/test 
directory and subdirectories.

[issue38308] Add optional weighting to statistics.harmonic_mean()

[Raymond Hettinger]

New submission from Raymond Hettinger :

Currently, harmonic_mean() is difficult to use in real applications because it 
assumes equal weighting.  While that is sometimes true, the API precludes a 
broad class of applications where the weights are uneven.

That is easily remedied with an optional *weights* argument modeled after the 
API for random.choices():

harmonic_mean(data, weights=None)


Examples


Suppose a car travels 40 km/hr for 5 km, and when traffic clears, speeds-up to 
60 km/hr for the remaining 30 km of the journey. What is the average speed?

>>> harmonic_mean([40, 60], weights=[5, 30])
56.0

Suppose an investor owns shares in each of three companies, with P/E 
(price/earning) ratios of 2.5, 3 and 10, and with market values of 10,000, 
7,200, and 12,900 respectively.  What is the weighted average P/E ratio for the 
investor’s portfolio?

>>> avg_pe = harmonic_mean([2.5, 3, 10], weights=[10_000, 7_200, 12_900])
>>> round(avg_pe, 1)
3.9


Existing workarounds


It is possible to use the current API for theses tasks, but it is inconvenient, 
awkward, slow, and only works with integer ratios:

>>> harmonic_mean([40]*5 + [60]*30)
56.0

>>> harmonic_mean([2.5]*10_000 + [3]*7_200 + [10]*12_900)
3.9141742522756826


Algorithm
-

Following the formula at 
https://en.wikipedia.org/wiki/Harmonic_mean#Weighted_harmonic_mean , the 
algorithm is straight forward:

def weighted_harmonic_mean(data, weights):
num = den = 0
for x, w in zip(data, weights):
num += w
den += w / x
return num / den


PR
--

If you're open to this suggestion, I'll work-up a PR modeled after the existing 
code and that uses _sum() and _fail_neg() for exactness and data validity 
checks.

[issue38296] unittest expectedFailure does not differentiate errors from failures

[Kit Yan Choi]

Kit Yan Choi  added the comment:

Pining Chris based on previous discussion in issue16997 ... Hope that's okay.

I notice that the language in my initial message also conflates error and 
failure. My apologies on the carelessness.

Just to clarify:


@unittest.expectedFailure
def test(self):
THIS_VARIABLE_IS_UNDEFINED  # ---> NameError


should give: ERROR (errors=1)
currently gives: OK (expected failures=1)


By fixing this, we can help projects to maintain their tests decorated with 
expectedFailure so that the tests remaining to be meaningful.

[issue38306] High level API for loop.run_in_executor(None, ...)?

[Antoine Pietri]

New submission from Antoine Pietri :

In 3.7 a lot of high level functions have been added to the asyncio API, but 
nothing to start blocking functions as non-blocking threads. You still have to 
call get_event_loop() then await loop.run_in_executor(None, callable). I think 
this pattern is *very* common and could use a higher level interface.

Would an API like this make sense?

async def create_thread(callable, *args, *, kwargs=None, loop=None, 
timeout=None)

Then it could just be used like this:

await asyncio.create_thread(my_blocking_read, 4096, timeout=10)

This API could wrap the run_in_executor in an asyncio.Task, that way
you wouldn't have to await it to start the thread. There's evidence
that this has confused people in the past:

[issue38305] https://2.python-requests.org/ missing TLS certicate

[Tim Laurence]

New submission from Tim Laurence :

I am unsure how to route this given the recent transition of Requests to PSF so 
my apologies if this is the wrong spot.

The page where I think most people look for Requests documentation appears to 
be broken 
  https://2.python-requests.org/

When I look more closely it looks like the server may not have a TLS 
certificate loaded. 

When I connect via http I get a redirection page to 
https://requests.kennethreitz.org/en/master/


Below is a dump of what openssl sees when trying to connect.

[issue38297] Imports at top of module is often not used

[Dominic Littlewood]

Dominic Littlewood <11dlittlew...@gmail.com> added the comment:

I've slightly adjusted the script to check for module-level imports not at the 
top of the file. If we permit things like this:

if condition:
import module
else:
do_something_sensible()

as long as they are at the top of the file, it seems that only one in ten 
modules have a problem. Which is better but not great.

A common pattern which breaks the rules is this:

# Large amounts of code here

if __name__ == '__main__':
import unittest
unittest.main('test/test_thisfile')

although that by no means accounts for all of the problems.
