After they marked the issue as "resolved" earlier this year I tested a

was still there.

I don't have a workaround. I am forced to stay with 2.7.3.

[issue8722] Documentation for __getattr__

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Before testing, let alone documenting, the status quo, I would like to be sure 
that suppressing the exception is truly the intended behavior.  Is there a way 
to get an annotated listing from git (given which patch, and therefore which 
person, is responsible for each line)?  I will try asking on pydev.

Calling __getattr__ on property failure is a behavior of __getattribute__, not 
of the property, and I would expect object.__getattribute__ to be tested 
wherever object is, but I have not found such tests.  If we do add a test, the 
best model in test_desc.py looks like `def test_module_subclasses(self):`.  The 
test class would only need __getattr__ and the faulty property.

class Foo(object):
def __getattr__(self, name):
print(f'Getattr {name}')
return True
@property
def bing(self):
print('Property bing')
raise AttributeError("blarg")

f = Foo()
print(f.bing)

#prints (which would be the log list in a test)
Property bing
Getattr bing
True

To do that you could enable the faulthandler module: 
https://docs.python.org/3/library/faulthandler.html

Also, it would be nice if you had a simple reproducer to share with us, though 
it may be difficult given the description you gave of your workload.

[issue29249] Pathlib glob ** bug

[Dustin Spicuzza]

Dustin Spicuzza  added the comment:

Because of backwards compatibility (despite a statement saying it's not 
guaranteed for pathlib), I think the best approach would be to create a 
'globmatch' function for PurePath instead of modifying the match function, and 
document that the match function does a different kind of matching. 

This isn't a patch for cpython per se (ironically, don't have time for that 
this month...), but here's a MIT-licensed gist that patches pathlib2 and adds a 
globmatch function to it, plus associated tests extracted from pathlib2 and my 
own ** related tests. Works for me, feel free to do with it as you wish.

[issue11594] 2to3 does not preserve line endings

[Jason R. Coombs]

Jason R. Coombs  added the comment:

This issue affected me today. I'm editing a codebase that has mixed line 
endings in different files. I'd like to patch for Python 3 support without 
changing line endings. Even invoking a single fixer (print), the line endings 
mutate. Since I'm running on macOS, the files with CRLF get LF line endings.

Answers [in this 
question](https://stackoverflow.com/questions/39028517/2to3-how-to-keep-newline-characters-from-input-file)
 suggest the mutation can be suppressed by altering the _to_system_newlines 
function, but the proposed fix has no effect on the Python 3.6 version of this 
routine.

I thought I'd encountered this issue before, but I realized after searching 
that I was thinking of issue10639, which may present a model for retaining the 
newlines when refactoring the code.

I found I was able to work around the issue by putting lib2to3-clean.py in my 
current directory:

import lib2to3.refactor
import runpy
import functools


if __name__ == '__main__':
lib2to3.refactor._open_with_encoding = functools.partial(open, 
newline='')
runpy.run_module('lib2to3')


And invoking `python -m lib2to3-clean` instead of `-m lib2to3`. The addition of 
newline='' follows the [guidance in the 
docs](https://docs.python.org/release/3.2/library/functions.html#open) on how 
to avoid mutating newlines.

I've released this functionality in [jaraco.develop 
4.0](https://pypi.org/project/jaraco.develop) so others can readily invoke it 
with `rwt jaraco.develop -- -m jaraco.develop.lib2to3`.

New protocol may speed up not only `reader.readexactly()`.
Every `reader.feed_data()` appends a new chunk to existing buffer.
We can try to read into unused tail of the buffer instead.

[Yury Selivanov]

Yury Selivanov  added the comment:

> Do you think it's possible to fold BufferedProtocol into Protocol?

It would be a backwards incompatible change :(

Coincidentally, there might be protocols that already implement 'get_buffer()' 
and 'buffer_updated()' methods that do something completely different.


> This would allow StreamReader to implement readinto().

We can easily refactor StreamReader to use 'BufferedProtocol'.  Methods like 
'readexactly()' would benefit from that.

[issue32251] Add asyncio.BufferedProtocol

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Do you think it's possible to fold BufferedProtocol into Protocol?
i.e., either `get_buffer()` returns None (the default) and `data_received()` is 
called with a bytes object, or `get_buffer()` returns a writable buffer and 
`buffer_updated()` is called with the number of bytes received into the buffer.

This would allow StreamReader to implement readinto().

[issue32251] Add asyncio.BufferedProtocol

[Yury Selivanov]

Yury Selivanov  added the comment:

> 1. What happens if size of read data is greater than pre-allocated buffer?

Let's say we have 2Kb of data in the socket's network buffer, and we only 
preallocated 0.5Kb in our buffer.  We will the receive 0.5Kb in our buffer, 
'Protocol.buffer_updated()' will be called with nbytes=512, and 1.5Kb of data 
will be left in the network buffer.  So the loop will call 
get_buffer()/buffer_updated() again, and the cycle will continue until there's 
no data left.


> 2. Is flow control logic changed or not? If I understand correctly 
> pause_reading() / resume_reading() continue to work as earlier.

Flow control will continue working absolutely the same for BufferedProtocols.


> I have another question: what happens if there is a partial read?
> For example, let's says I return a 1024-bytes buffer in get_buffer(), but 
> recv_into() receives data in 512 chunks.  Is it:

It will be as follows:

1. Protocol.get_buffer() is called, returns 1024 bytes buffer
2. recv_into() receives 512 bytes, writes them in buf[0:512]
3. Protocol.buffer_updated() is called with nbytes=512

Now it's the responsibility of the Protocol to return a correct view over 
buffer the next time `get_buffer()` is called.

The general idea is to:

1. allocate a big buffer

2. keep track of how much data we have in that buffer, let's say we have a 
'length' integer for that.

3. when get_buffer() is called, return 'memoryview(big_buffer)[length:]'

4. when buffer_updated(nbytes) is called, do 'length += nbytes; 
parse_buffer_if_possible()'

I've implemented precisely this approach here: 
https://gist.github.com/1st1/1c606e5b83ef0e9c41faf21564d75ad7#file-get_buffer_bench-py-L27-L43

[issue32252] test_regrtest leaves a test_python_* directory in TEMPDIR

[STINNER Victor]

Can you please explain how to reproduce the bug? (Which commands should I type?)

What is your /proc/sys/kernel/core_pattern?

On my Fedora 27, /proc/sys/kernel/core_pattern is 
"|/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %e".

[issue8722] Documentation for __getattr__

[Cheryl Sabella]

Cheryl Sabella  added the comment:

Terry,

Thanks for clarifying with this example.  I hadn't tried this when I was 
playing with the other example.  I guess __getattribute__ might be defined by a 
class, but generally wouldn't be called directly, so the use of __getattr__ and 
__getattribute__ and the raising of AttributeError is more for an 
`attributeref` 
(https://docs.python.org/3/reference/expressions.html#attribute-references) 
usage?

This did a "click" in my head. It works now with `nargs='?'` and 
`const='MediaProfile000'` as expected, thanks!

I am really sorry for the noise, due to misunderstanding while reading 
(skipping-throuhg?) Python documentation.

[issue32251] Add asyncio.BufferedProtocol

[Antoine Pitrou]

Antoine Pitrou  added the comment:

I have another question: what happens if there is a partial read?

For example, let's says I return a 1024-bytes buffer in get_buffer(), but 
recv_into() receives data in 512 chunks.  Is it:

1. getbuffer() is called, returns 1024 bytes buffer
2. recv_into() receives 512 bytes, writes them in buf[0:512]
3. recv_into() receives another 512 bytes, writes them in buf[512:1024]

or is it:

1. getbuffer() is called, returns 1024 bytes buffer
2. recv_into() receives 512 bytes, writes them in buf[0:512]
3. getbuffer() is called, returns another 1024 bytes buffer
4. recv_into() receives 512 bytes, writes them in newbuf[0:512]

[issue32246] test_regrtest alters the execution environment on Android

[Xavier de Gaye]

Xavier de Gaye  added the comment:

I agree that test_crashed() should be skipped on Android anyway and I will 
create a PR to skip the test.

If I understand correctly, there may be another nasty bug that is revealed when 
test_regrstest fails with the environment altered:

How is it possible that the new file that alters the environment be a 
test_python_* directory (see my initial post) when all the tests are run inside 
a TEMPDIR/test_python_* directory. The 'files' environment is checked within a 
TEMPDIR/test_python_* and not within TEMPDIR, no ?

I found a new point that may help understand this problem:

* On Android TEMPDIR is built from tempfile.gettempdir() that uses the TMPDIR 
environment variable which is set by Android to /data/local/tmp. The tests are 
run in /data/local/tmp/python [1], this is also the value of $SYS_EXEC_PREFIX 
and thus where are installed Python machine-specific binaries.

* When TMPDIR is set to /data/local/tmp/python/tmp, which makes more sense 
here, test_regrstest is ok and does not change the environment.

[1] This is the only location where a shell user may have both write and exec 
permissions, the Android applications have those permissions here too and in 
their own dedicated locations on /data/data.

[issue32254] documentation builds (even local ones) refer to https://docs.python.org/

[Matthias Klose]

New submission from Matthias Klose :

lintian (the Debian packaging checker) recently started flagging so-called 
"privacy-breach" issues:

https://lintian.debian.org/maintainer/d...@debian.org.html#python2.7

python2.7-doc
W privacy-breach-generic
usr/share/doc/python2.7/html/about.html (https://docs.python.org/2/about.html)
usr/share/doc/python2.7/html/bugs.html (https://docs.python.org/2/bugs.html)
usr/share/doc/python2.7/html/c-api/abstract.html 
(https://docs.python.org/2/c-api/abstract.html)
[...]
and 500 more.

that's because Doc/tools/templates/layout.html hardcodes an absolute URL and 
there is no configure way to change it.  I don't think that local builds should 
point to the same single-point-of-failure URL, but use local references instead.

2. Is flow control logic changed or not? If I understand correctly 
pause_reading() / resume_reading() continue to work as earlier.

[issue27645] Supporting native backup facility of SQLite

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

It seems to me that the code could be much simpler (and more bugfree) if 
support only a Connection instance as a target. It is easy to create a 
Connection instance in Python:

with sqlite3.connect(filename) as dest:
source.backup(dest)

But this would save around 50 lines of complex C code. And I'm not sure this 
code is correct.
