> Still planned for 3.7: [...]

Eric, please try to get everything you want done and into master as soon as 
possible, then produce a PR for 3.7, and then we can review it and make a 
decision if it is appropriate for 3.7.  As I've mentioned in msg310448 and 
stated elsewhere, the expectation is that the few post-b1 feature freeze 
extensions granted were only for b2.  Even changes limited to Lib/test can 
break buildbots and downstream users' testing and take multiple releases to 
stabilize.  Thanks for your work on this!

[issue32604] Expose the subinterpreters C-API in Python for testing use.

[Eric Snow]

Eric Snow  added the comment:

Still planned for 3.7:

1. add more tests in Lib/test/test__xxsubinterpreters.py
2. add test.support.interpreters (high-level module)
3. add more tests in Lib/test/test_interpreters.py

At that point I'll start using the high-level module in tests for 
subinterpreter functionality and for other open issues (e.g. #10915, #15751), 
aiming to improve stability of the feature.

Eric Snow  added the comment:

As far as I know, everything related to this issue is in a stable state.  I 
have not been able to determine any way in which the reported memory leak (in 
test_multiprocessing_fork) could be related.  Sorry, I didn't notice the 
release blocker priority.

I do not plan on landing any further changes here for beta2.  However, I do 
plan on a few more additions under Lib/test before we go final.

[Eric V. Smith]

New submission from Eric V. Smith :

This is a temporary measure until we can better define how frozen inheritance 
should work. In the meantime, disallow:

- frozen inherited from non-frozen
- non-frozen inherited from frozen

[issue15767] add ModuleNotFoundError

[Christoph Groth]

Christoph Groth  added the comment:

In the above, please replace "understand the decision" by "understand the 
usefulness of it".

In the above discussion, as an alternative to a new exception, it was proposed 
to add an attribute to ImportError ('reason'), but then people seemed to agree 
that this is quite useless outside of importlib (msg192261).  But then I don't 
understand why the original idea of the exception was revived.

My curiosity was piqued when I saw ModuleNotFoundError, so I decided to look it

not understand the decision, so I allowed myself to ask,  also because I 
believe that when new features are introduced it should be clear what they are 
good for.  That's all.

[issue21417] Compression level for zipfile

[Gregory P. Smith]

Gregory P. Smith  added the comment:

keeping the conversation in one place, the code review comment was: "I've 
prefixed this with an underscore because it's not exposed when reading back. 
ZipInfo has another "private" attribute, _raw_time"

compresslevel is documented on the public APIs where it appears, I do not 
believe it needs to be a public attribute within ZipInfo given the above as 
that is an implementation detail.  If we ever find a good reason to make it 
public in the future we can add a property.

I'm fine with undoing this for 3.7 in light of the many things we don't do 
"right" all over the place with path like objects.

subprocess still presents as a mix of high and low level APIs so if we accept a 
path like object in a subset of places it seems like that'll add complexity to 
the APIs rather than being consistent.

[issue32959] zipimport fails when the ZIP archive contains more than 65535 files

When trying to import a module from a ZIP archive containing more than 65535 
files, the import process fails:

I think the problem is related to the zipimport module not handling the 'zip64

[issue31711] ssl.SSLSocket.send(b"") fails

[Nathaniel Smith]

Nathaniel Smith  added the comment:

My point is that SSL_write(3ssl) says "WARNING: When calling SSL_write() with 
num=0 bytes to be sent the behaviour is undefined."

Apparently on the particular openssl you're looking at, it gives 
SSL_ERROR_SYSCALL with error code == 0 and len == 0, but the openssl devs claim 
this is some arbitrary thing that shouldn't be depended on.

Just as a general principle it would be nice if performing ordinary operations 
on an SSLSocket from Python did not invoke undefined behavior :-)

[issue32937] Multiprocessing worker functions not terminating with a large number of processes and a manager

[EricG]

EricG  added the comment:

Making some further observations, when I set processes = 12, for example, I can 
see 12 separate python processes + 4 additional processes also created which I 
assume are setup for the manager and, perhaps, other purposes.

Now, what makes these 4 additional processes interesting is that for me, 
multiprocessing.cpu_count() returns 24. And, it is when I set processes = 20 
that the python code will sometimes terminate successfully. 20 + 4 = 24...so I 
am using every single cpu in that situation.

However, as noted, when I set processes = 19, it will always terminate 
successfully. 19 + 4 < 24...there is at least one cpu not assigned any work.

Perhaps there some some kind of race condition or swapping around of data 
structures or something that only happens on macOS when every cpu is in use by 
python for this purpose.

message ("see msg182332") that *predates* your judgment that "outside importlib 
there shouldn't be a need to distinguish between the cases".  Otherwise Eric 
says that he finds "the exception to be very useful", but frankly, I don't see 
why (outside of importlib or backports of it).  What changed since msg192263?

[issue23808] Symlink to directory on Windows 8

[Alexey Izbyshev]

Alexey Izbyshev  added the comment:

This behavior is not specific to just Windows 8. Symlinks to directories are 
treated as directories on Windows, in particular, they should be removed with 
RemoveDirectory, not DeleteFile.

Is there any reason this issue is still open?

[issue32958] Urllib proxy_bypass crashes for urls containing long basic auth strings

[Aaron Black]

New submission from Aaron Black :

While working on a custom conda channel with authentication, I ran into the 
following UnicodeError:

Traceback (most recent call last):
  File 
"/Users/ablack/miniconda3/lib/python3.6/site-packages/conda/core/repodata.py",

  File "/Users/ablack/miniconda3/lib/python3.6/urllib/request.py", line 2562, 
in _proxy_bypass_macosx_sysconf
hostIP = socket.gethostbyname(hostonly)
UnicodeError: encoding with 'idna' codec failed (UnicodeError: label empty or 
too long)

The error can be consistently reproduced when the first substring of the url 
hostname is greater than 64 characters long, as in 
"0123456789012345678901234567890123456789012345678901234567890123.example.com". 
This wouldn't be a problem, except that it doesn't seem to separate out 
credentials from the first substring of the hostname so the entire 
"[user]:[secret]@XXX" section must be less than 65 characters long. This is 
problematic for services that use longer API keys and expect their submission 
over basic auth.

[issue32305] Namespace packages have inconsistent __file__ and __spec__.origin

[Ned Deily]

Ned Deily  added the comment:

Note that this change was originally also backported to 3.6 in PR 5504 but, due 
to third-party package regressions discovered in pre-release testing, the 3.6 
change was reverted in PR 5591 prior to release of 3.6.5rc1.

[issue17288] cannot jump from a 'return' or 'exception' trace event

[Xavier de Gaye]

Xavier de Gaye  added the comment:

Those are the changes with the current behavior from the behavior in 3.5 
observed at the time of the initial bug report:
  python 3.7:
return.pyUnchanged.
exception.py After a jump from the 'exception' event into the previous 
statement, the ensuing 'step' command triggers a trace 'return' event.
jump.py  The sequence of trace events is unchanged and Python aborts 
now at the last 'step' command with:
   python: Python/ceval.c:1083: _PyEval_EvalFrameDefault: 
Assertion `STACK_LEVEL() <= co->co_stacksize' failed.
  python 3.8:
return.pyUnchanged.
exception.py Unchanged from 3.7.
jump.py  The sequence of trace events is unchanged and the last 'step' 
command prints now the cryptic error msg:
   TypeError: 'NoneType' object is not callable
   > /path/to/jump.py(2)gen()->0
   -> for i in range(1):

Applying the last patch fixes both 3.7 and 3.8. I can build a PR from this 
patch. An explanation should be given for the behavior of 3.7 and 3.8 in the 
jump.py case.

[issue32957] distutils.command.install checks truthiness of .ext_modules instead of calling .has_ext_modules()

[Korijn Van Golen]

New submission from Korijn Van Golen :

distutils' Distribution class has a method has_ext_modules() that is used to 
determine if any extension modules are included in a distribution. There 
remains a call site in distutils.command.install where 
self.distribution.ext_modules is directly tested for truthiness, rather than 
calling has_ext_modules. This causes inconsistent behavior, e.g. when 
overriding has_ext_modules in a Distribution subclass.

[issue15767] add ModuleNotFoundError

[Christoph Groth]

Christoph Groth  added the comment:

I'm trying to understand why ModuleNotFoundError was added to 3.6.  The "what's 
new" entry links to this page.

Looking at the discussion, Guido said in 2013: "Right.  Outside importlib there 
shouldn't be a need to distinguish between the cases (especially given that the 
exception works differently than its name suggests).".  Then, three years 
later, he supports the inclusion of the patch, without that any new arguments 
had been given.

Could someone explain (or link to) what happened inbetween?

[issue32937] Multiprocessing worker functions not terminating with a large number of processes and a manager

[EricG]

EricG  added the comment:

If I do:

from queue import Queue

messages = Queue()

No messages are printed. I believe this is expected as a regular Queue cannot 
be shared between processes. It was a problem that the manager was designed to 
solve.

I am using a MacPro running 10.3.2
Python 3.6.4

It would not surprise me if this were an OS specific issue. To reproduce it may 
requiring using a Mac with a high number of cores.

It is trivially reproducible for me.

[issue31453] Debian Sid/Buster: Cannot enable TLS 1.0/1.1 with PROTOCOL_TLS

[Christian Heimes]

Christian Heimes  added the comment:

I have closed the feature newer BPO-32609 in favor of this bug because Ned gave 
this bug a deferred blocker priority.


OpenSSL 1.1 has introduced a new API to set the minimum and maximum supported 
protocol version. The API is easier to use than the old OP_NO_TLSv1 option 
flags, too

https://www.openssl.org/docs/man1.1.0/ssl/SSL_CTX_set_min_proto_version.html

Debian used the new setters to disable TLS 1.0 and 1.1 in testing, #31453. The 
old TLS versions have been enabled again for now. Python must expose the new 
API in case Debian decides to disable them again. Another $DIST has considered 
to implement a virtually the same policy as Debian.

I also like to deprecate the old OP_NO_TLSv1 et al. flags in favor of the new 
API. The option flags are awkward to use and easy to get wrong. For example 
applications must not leave holes in the OP_NO range (e.g. allow TLS 1.0 and 
1.2 but disable 1.1).

Strike that one, I didn't read into PEP-0501 deep enough before replying. 

Yes, `i"format"` is what I'm talking about.

[issue32954] Lazy Literal String Interpolation (PEP-498-based fl-strings)

[Arcadiy Ivanov]

Arcadiy Ivanov  added the comment:

@eric.smith

Thanks! I was looking for such a general-purpose proposal but could not find 
it. 

Although general-purpose mechanism that would allow pluggable constructs like 
`sh`, `html`, `sql` and the like is awesome and very desirable (especially sh 
in preference of Popen madness), string formatting/concatenation is IMO a 
fundamental concept (hence PEP-498 is in core with specialized opcodes instead 
of being deferred to be a general purpose pluggable PEP-501 implementation).

[issue32954] Lazy Literal String Interpolation (PEP-498-based fl-strings)

[Arcadiy Ivanov]

Arcadiy Ivanov  added the comment:

@serhiy.storchaka Of course a similar pattern can be implemented via a class 
(or even without one as I've shown below). 

But you can clearly notice that in your example:

1) There are tons of boilerplate (as in mine with lambdas).
2) It's going to be slower than a core implementation with specialized objects.
3) It can't be made to cooperate with a FORMAT_VALUE/BUILD_STRING - 
intermediate strings will still be produced.
