[issue38739] pyperformance html5lib cannot import Mapping (and fails)

2019-11-07 Thread Karthikeyan Singaravelan



Karthikeyan Singaravelan  added the comment:

Sorry, I misread the traceback itself as if it's from pip. It's from html5lib 
being incompatible with 3.9 as per the latest release on 1.0.1 (Dec 7, 2017) . 
There is an issue to request new release with the fix at 
https://github.com/html5lib/html5lib-python/issues/419 . Maybe you can try 
building html5lib from their master branch to be used in pyperformance. I would 
propose closing it as third party.

[issue38729] mock.create_autospec generates incorrect signature for some decorated methods

2019-11-07 Thread Karthikeyan Singaravelan



Karthikeyan Singaravelan  added the comment:

If I understand this correctly, when an autospec of a class is created the 
attributes themselves of the given class are autospecced. During autospec of 
attributes it's modelled upon __call__'s signature for the given attributes 
[0]. Here you are wrapping the method's inside a class with Wrapper with a 
custom __call__ implementation. During actual calls the chain goes through 
__call__ and executes __get__ where bound method is called. But in mock I am 
not sure of a way where it can figure out __call__ and then look more into the 
body to see if there are actual calls being made to be mocked with current 
implementation just going through signature of __call__.

New submission from Mark :

in example header is "[i love [python] lang]"
parse as "i love [python", only up to the first character ']'.

now saving works correctly, but reading does not

[issue38740] Line count mis match between open() vs sys.stdin api calls

2019-11-07 Thread Thamme Gowda



New submission from Thamme Gowda :

I ran into a line count mismatch bug and I narrowed it down to 9 lines where 
the line break handling is causing an issue. Please find the attachment named 
line_break_err.txt to reproduce the below. 


$ md5sum line_break_err.txt
5dea501b8e299a0ece94d85977728545  line_break_err.txt

# wc says there are 9 lines
$ wc -l line_break_err.txt
9 line_break_err.txt

# if I read from sys.stdin, I get 9 lines
$ python -c 'import sys; print(sum(1 for x in sys.stdin))' < line_break_err.txt

# but... if I use a open() call, i get 18 
$ python -c 'import sys; print("Linecount=", sum(1 for x in 
open(sys.argv[1])))' line_break_err.txt
Linecount= 18

# changing encoding or error handling has no effect
$ python -c 'import sys; print("Linecount=", sum(1 for x in open(sys.argv[1], 
"r", encoding="utf-8", errors="replace")))' line_break_err.txt
Linecount= 18

$ python -c 'import sys; print("Linecount=", sum(1 for x in open(sys.argv[1], 
"r", encoding="utf-8", errors="ignore")))' line_break_err.txt
Linecount= 18
# but, not just wc, even awk says there are only 9 lines
$ awk 'END {print "Linecount=", NR}' line_break_err.txt
Linecount= 9

# let's see python 2 using io
# python2 -c 'import sys,io; print("Linecount=", sum(1 for x in 
io.open(sys.argv[1],  encoding="ascii", errors="ignore")))' line_break_err.txt
('Linecount=', 18)

# But this one which we no longer use somehow gets it right
$ python2 -c 'import sys; print("Linecount=", sum(1 for x in 
open(sys.argv[1])))' line_break_err.txt
('Linecount=', 9)


Tested it on 
1. Linux 
Python 3.7.3 | packaged by conda-forge | (default, Jul  1 2019, 21:52:21)
[GCC 7.3.0] :: Anaconda, Inc. on linux


2. OSX
Python 3.7.3 (default, Mar 27 2019, 16:54:48)
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin

3. python 2 on OSX
Python 2.7.16 (default, Jun 19 2019, 07:40:37)
[GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.46.4)] on darwin

 

P.S. 
this is my first issue created. If this issue is a duplicate, I am happy to 
close it.

Questions on working with unittest.IsolatedAsyncioTestCase

2019-11-07 Thread Mond Wan

Hello all,

I would like to ask for helps on working with
**unittest.IsolatedAsyncioTestCase**.

Q1: How to handle asyncio.CancelledError inside IsolatedAsyncioTestCase.

My test is hanging up if there are futures being cancelled some how. Is there a
way for me to configure IsolatedAsyncioTestCase to throw any exceptions
to crash the main program such that I can read the line number?

I have also issue a post on stackoverflow, which include the codes I have
written for explaining the question.

Stackoverflow:
https://stackoverflow.com/questions/58744043/how-to-handle-cancellederror-with-python-3-8-unittest-isolatedasynciotestcase

Q2: addAsyncCleanup vs asyncTearDown?

In the py3.8 manual, there is a method **addAsyncCleanup** for cleaning up
stuff in async way. Why we need this instead of merging them altogether
into **asyncTearDown** at all?

Q3: Is it possible to configure a timeout mechanism for IsolatedAsyncioTestCase?

During my development, my tests always pending in somewhere. I cannot located
them until I add print statements line by line. Is it possible to
configure the IsolatedAsyncioTestCase to crash the test, with line number,
after specific period if such future is not resolved?

Thanks for your time
