[issue28022] SSL releated deprecation for 3.6

[Nick Coghlan]

Nick Coghlan added the comment:

Leaving the option of context caching entirely to the caller would definitely 
make things simpler - my main interest is just in avoiding a hard compatibility 
break for folks that aren't doing anything particularly wrong, by which I mean 
specifically cases where a wrap_socket() implementation like this one would 
continue to work for them:

def wrap_socket(sock, *args, *kwds):
return ssl.get_default_context().wrap_socket(sock, *args, **kwds)

[issue23591] enum: Add Flags and IntFlags

[Vedran Čačić]

Vedran Čačić added the comment:

> Which means it has methods such as __getitem__, __setitem__, etc., which 
> means those methods can implement whatever is needed to give the namespace 
> the desired semantics (within Python syntax).

Ah, _that_'s what you had in mind. (All this time, I thought _auto_ was just a 
shorter name for _generate_next_value_.:) I'm ok with that. But aren't we then 
back to square one? (Using magic of the same kind as the "declarative style" 
that Raymond pronounced not Pythonic enough.)

Even Raymond says
> As long as _auto_ has been defined somewhere (i.e. from enum import _auto_), 
> it is normal Python

I'm sure he didn't think of the loophole you're currently exploiting. :-D

But anyway, I'm happy. Parentheses are there, so the intuition of calling a 
function to execute code is respected, and if you get out free with this hack, 
it opens a door a bit wider for complete declarative solution in the future.

Maybe we should also fix ctypes to use an LRU cache like

[issue27213] Rework CALL_FUNCTION* opcodes

[STINNER Victor]

STINNER Victor added the comment:

Author: Berker Peksag (berker.peksag) * (Python committer)  Date: 
2016-09-11 08:55

Berker: "I'm getting segfaults with a77756e480c2 (thanks to 'hg bisect') on 
Ubuntu 12.04 (...)
test_recursionlimit_recovery (...) test_main_recursion_error (...)"

We should check if the change counts correctly the number of frames.

In callfunc-10.patch, Serhiy modified a counter related to recursion 
limit/number of frames to fix test_traceback (issue #28050). He wrote on the 
review:

"Seems the number 50 is arbitrary. Now we should increase it. Why? This issue 
needs further investigation. Maybe this is a sign of regression."

To me, it's suspicious that we have to modify an unit test. Changing the opcode 
or internals must not have an impact on unit tests on recursion error.

Note: It might also be related to my FASTCALL changes, but you wrote that "hg 
bisect" pointed you to this change.


Berker: "I'm also getting the following error with Serhiy's latest patch: 
python: Objects/abstract.c:2385: _PyStack_AsDict: Assertion 
`PyDict_GetItem(kwdict, key) != ((void *)0)' failed."

This one might be related to the compact dict change.


Note: Just to make be sure that it is not a local issue, please try a "make 
distclean" and make sure that all .pyc files are removed, and then recompile 
Python.

[issue15819] Unable to build Python out-of-tree when source tree is readonly.

[Martin Panter]

Martin Panter added the comment:

Perhaps there should be a comment explaining that you can’t write to $(srcdir). 
Or even a buildbot that does an out-of-tree build. Every now and then I seem to 
be defending against patches that want to change targets back to $(srcdir).

Also, Trent’s last change, revision 65b3c41052b6, does not seem to work. 
Apparently $abs_srcdir etc are only valid when substituted in a makefile, and 
are not valid in the configure script: 
. I will try 
to post a patch that addresses this to Issue 28066.

I forgot to mention that in my earlier comment. I usually run "make distclean"

[issue27932] platform.win32_ver() leaks in 2.7.12

[Eryk Sun]

Eryk Sun added the comment:

Limiting the pointer-type cache could be a problem. It's expected that 
POINTER() returns a reference to an existing pointer type. ctypes uses Python 
types to ensure compatible C data types. For example:

LP_c_int = ctypes.POINTER(ctypes.c_int)

class LP_c_int_uncached(ctypes._Pointer):
_type_ = ctypes.c_int

>>> arr = (LP_c_int * 2)()
>>> ctypes.POINTER(ctypes.c_int) is LP_c_int
True
>>> arr[0] = ctypes.POINTER(ctypes.c_int)()
>>> arr[1] = LP_c_int_uncached()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: incompatible types, LP_c_int_uncached instance
instead of LP_c_int instance

The docs could warn users that the cache used by ctypes.POINTER(), and 
implicitly by ctypes.pointer(), will leak memory if it's called with a type 
that's created at function scope instead of at module or class-body scope.

[issue28066] [Patch] Fix the ability to cross compile Python when doing a rebuild of importlib.h

[Martin Panter]

Martin Panter added the comment:

There are various tricky cases to be considered with the regenerated files like 
importlib.h. One of them is that you are supposed to be able to build Python 
from a read-only source tree. See Issue 15819. Writing files into $(srcdir) 
would break this.

Also, as I just wrote in that bug, the built Python/importlib.h is already 
supposed to be searchable. However the logic seems to be broken. Can you see if 
this patch helps?

[issue27364] Deprecate invalid escape sequences in str/bytes

[Chi Hsuan Yen]

Chi Hsuan Yen added the comment:

Currently the deprecation message is not so useful when fixing lots of files in 
a large project. For example, I have two files foo.py and bar.py:

# foo.py
import bar

# bar.py
print('\d')

It gives:
$ python3.6 -W error foo.py
Traceback (most recent call last):
  File "foo.py", line 1, in 
import bar
DeprecationWarning: invalid escape sequence '\d'

Things are worse when __import__, imp or importlib are involved. I have to add 
some codes to show which module is imported.

It would be better to have at least filenames and line numbers:
$ ./python -W error foo.py
Traceback (most recent call last):
  File "foo.py", line 1, in 
import bar
  File "/home/yen/Projects/cpython/build/bar.py", line 1
print('\d')
 ^
SyntaxError: (deprecated usage) invalid escape sequence '\d'

I have a naive try that prints more information. Raising SyntaxError may not be 
a good idea, anyway.

[Antti Haapala]

Antti Haapala added the comment:

There is no need to ifdef anything, the memcpy is the only correct way to do 
it. As memcpy is also a reserved identifier in C, the compiler can and will 
optimize this into a 64-bit access on those platforms where it can be safely 
done so (x86 for example), e.g. GCC compiles

uint64_t func(char *buf) {
uint64_t rv;
memcpy(&rv, buf+3, sizeof(rv));
return rv;
}

into

movq3(%rdi), %rax

[issue15819] Unable to build Python out-of-tree when source tree is readonly.

[Kubilay Kocak]

Kubilay Kocak added the comment:

@Martin Maybe Zach (nosey'd) can help us get an out-of-tree builder set up?

If this is relevant for 3.5+, versions should be updated accordingly.

[issue27213] Rework CALL_FUNCTION* opcodes

[Berker Peksag]

Berker Peksag added the comment:

Thanks, Serhiy.

test_recursionlimit_recovery in test_sys passed, but now I'm getting the 
following failure:

FAIL: test_recursionlimit_fatalerror (test.test_sys.SysModuleTest)

I modified test_recursionlimit_fatalerror to use subTest() and it looks like 
the test passed when sys.setrecursionlimit(50). See i=1000 in the following 
output:

==
FAIL: test_recursionlimit_fatalerror (test.test_sys.SysModuleTest) (i=1000)

test_runpy still segfaults:

I wrote a quick and dirty reproducer for this. I can attach here if you think 
it would be useful for debugging.

[issue28076] Variable annotations should be mangled for private names

[Ivan Levkivskyi]

New submission from Ivan Levkivskyi:

Variable annotations for private names are stored in __annotations__ without 
name mangling. This is inconsistent with how function annotations behave:

class C:
   def meth(__x: int): ...

assert C.meth.__annotations__ == {'_C__x': int}

The attached patch fixes variable annotations to behave in the same way:

class C:
__foo: int = 1

assert C.__dict__['_C_foo'] == 1
assert C.__annotations__['_C__foo'] == int

[issue28075] os.stat fails when access is denied

[Eryk Sun]

Eryk Sun added the comment:

Python 3's os.stat tries to open a handle for the file or directory in order to 
call GetFileInformationByHandle. Opening a file handle via CreateFile requests 
at least FILE_READ_ATTRIBUTES and SYNCHRONIZE access when it calls 
NtCreateFile. If access is denied, os.stat is supposed to fall back on the 
basic WIN32_FIND_DATA information from FindFirstFile. However, it's not working 
as intended. For example:

>>> import os
>>> os.mkdir('test')
>>> os.system('icacls test /deny Users:(S,RA)')
processed file: test
Successfully processed 1 files; Failed processing 0 files
0

>>> os.stat('test')
Traceback (most recent call last):
  File "", line 1, in 
PermissionError: [WinError 5] Access is denied: 'test'

The problem is that it's mistakenly checking for ERROR_SHARING_VIOLATION 
instead of ERROR_ACCESS_DENIED. Technically, getting a sharing violation should 
be impossible here. That only applies to requesting execute (traverse), read 
(list), write (add file), append (add subdirectory), or delete access for the 
contents of the file or directory, not its metadata.

After modifying the code to instead check for ERROR_ACCESS_DENIED, os.stat 
correctly falls back on using the file attributes from the WIN32_FIND_DATA:

>>> os.stat('test')
os.stat_result(st_mode=16895, st_ino=0, st_dev=0, st_nlink=0, 
st_uid=0, st_gid=0, st_size=0, st_atime=1473589600, 
st_mtime=1473589600, st_ctime=1473589600)

[issue23591] enum: Add Flags and IntFlags

[Ethan Furman]

Ethan Furman added the comment:

> Ah, _that_'s what you had in mind. (All this time, I thought _auto_

Not at all.  The concern with that proposal (issue26988: AutoEnum via 
completely omitting values of any kind) was the transformation of a NameError 
into a value.  The current method is taking a unique object and transforming 
that into a value, which is entirely analagous to what Enum already does.

Besides being convenient, it's also necessary to present a cohesive, non-leaky 
abstraction to the user where Flag is concerned: using ints as the flag values 
is entirely an implementation detail, but without auto the user would be forced 
to manage that implementation detail when creating the Flag, which negates much 
of Flag's value.

[issue28078] Silence resource warnings in test_socket

[Christian Heimes]

Christian Heimes added the comment:

Thanks! The first fix looks good. For the second one I'd rather wrap the test 
body in a with statement:

def test_sendmsg_afalg_args(self):
sock = socket.socket(socket.AF_ALG, socket.SOCK_SEQPACKET, 0)
with sock:
with self.assertRaises(TypeError):
sock.sendmsg_afalg()
...

[issue28079] Update typing and test typing from python/typing repo

[Ivan Levkivskyi]

Ivan Levkivskyi added the comment:

I have noticed that some code could be simplified, since it is 
backward-compatible even with 3.2, but I think it is easiest to keep the source 
here in sync with what is on python/typing.

Um, if I apply this to 3.5 it works, but if I then merge forward to 3.6

[issue28079] Update typing and test typing from python/typing repo

[Ivan Levkivskyi]

Ivan Levkivskyi added the comment:

I could guess this is because some changes have been already integrated by 
patch that implemented PEP 526.

If this would help here is a separate patch that should apply cleanly to 3.6

[issue27405] Ability to trace Tcl commands executed by Tkinter

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Here is more mature patch. Now you can set tracing function with the 
tkinter.Tk.settrace() method. Tracing function takes the single argument -- a 
tuple containing the command and arguments. If set global tkinter.debug to 
True, the tracing function of newly created Tk object will be set to 
tkinter.print_command that prints the command to stdout.

[issue28068] Error in freeze.py due to unguarded sys.abiflags usage under Windows

[Gevorg Voskanyan]

Gevorg Voskanyan added the comment:

Thanks for the patch! It makes the error go away for me, but only because 
`ishome` is True in my case. Were it False, it would fail the same way on the 
line containing sys.abiflags .
I think this line in the patch:
flagged_version = version + sys.abiflags
should be changed to:
flagged_version = version + abiflags
That way I get no errors regardless of the value of `ishome`.

[issue27701] [posixmodule] [Refactoring patch] Simply call into *at() functions unconditionally when present

[Ed Schouten]

Ed Schouten added the comment:

Hmmm... Taking a second look at my patch: I still think it's conceptually a 
good idea to pursue this, but I think it may be wiser to first focus on the 
bits that are strictly necessary from my side. The patch that I've posted 
previously has the disadvantage that it's hard to grasp what belongs to gether.

Attached is a trimmed down version of my original patch that only focuses on 
patching up the os_*_impl()s to use the *at() functions exclusively if 
possible. Hopefully this change should be fairly easy to understand.

Any thoughts?
