I have tested on my laptop (fedora 29) and I can't reproduce these memory leaks.

I suppose we can not debug on the builder...

[issue36338] urlparse of urllib returns wrong hostname

[Xianbo Wang]

New submission from Xianbo Wang :

The urlparse function in Python urllib returns the wrong hostname when parsing 
URL crafted by the malicious user. This may be caused by incorrect handling of 
IPv6 addresses. The bug could lead to open redirect in web applications which 
rely on urlparse to extract and validate the domain of redirection URL.

The test case is as follows:

>>> from urllib.parse import urlparse
>>> urlparse(urlparse('http://benign.com\[attacker.com]').hostname
>>> 'attacker.com'

The correct behavior should be raising an invalid URL exception.

[issue36318] Adding support for setting the "disabled" attribute of loggers from logging.config.dictConfig

[Géry]

Géry  added the comment:

Actually people do this all the time, to deactivate the logging of some 
third-party libraries (me included). For instance:

* 
https://stackoverflow.com/questions/24344045/how-can-i-completely-remove-any-logging-from-requests-module-in-python
* 
https://stackoverflow.com/questions/34598952/how-to-disable-info-logging-from-a-third-party-module-in-python
* 
https://stackoverflow.com/questions/38102291/turn-off-logging-in-schedule-library

And currently we can only use either solution 2 or 3 with 
`logging.config.dictConfig` (which are more verbose and less explicit). We 
cannot use solution 1 with `logging.config.dictConfig`.

In addition, all public attributes in the `__init__` methods of the 
`logging.Formatter`, `logging.Handler` and `logging.Logger` classes can be set 
from `logging.config.dictConfig`, except the `disabled` attribute, which is 
inconsistent.

[issue36340] 3.7.3rc1 Install Certificates fails on macOS

[Dima Tisnek]

New submission from Dima Tisnek :

I've just installed Python 3.7.3rc1 for macOS 10.9 or later from the macOS 
64-bit installer.

I've clicked the `Install Certificates.command`, which opened a Terminal, ran 
and failed with:

[Process completed]
```

I was able to run the same command from my regular shell (iTerm2, fish, $PATH 
addons, etc.) and that completed just fine and installed certifi==2019.3.9

Either there's just something wrong with my system (what?) or the initial 
experience for average user is broken (unlikely?)...

[issue36340] 3.7.3rc1 Install Certificates fails on macOS

[Dima Tisnek]

Dima Tisnek  added the comment:

More system info:
I've had 3.7.2 installed from official installer prior to this.
Before that, I had 3.7.1 installed from official installer.
I also have 3.8a2. 3.6.8, 2.7.15 on the system, as well as an odd version from 
Homebrew.

My system site-packages for 3.7 now (after manual fix) contains ceritifi, pip 
(19.0.3), setuptools, pkg_resources, easy_install.py and README.

[issue36297] Remove unicode_internal codec

[STINNER Victor]

STINNER Victor  added the comment:

Thanks INADA-san. IMHO Python has too many codecs, it's painful to maintain 
them. So it's nice to see deprecate ones to be removed.

Next step: remove all deprecated APIs using Py_UNICODE* :-D (I know that Serhiy 
is working on that.)

[issue36337] Use socket.sendall()/send() send data larger than 2GB will be truncated and return None, without exception raised.

[kmiku7]

kmiku7  added the comment:

Thanks for your contribute! I just have read your PR on github.
Because I am not familiar about how to contribute a patch, I doubt it's 
reasonable to write a test which will consuming more than 2GB memory space? 
Because if write a test to cover this case, we will build a string larger than 
2GB, and use socket to send it. Dose the machine running tests have enough 
memory resource?

[issue36337] Use socket.sendall()/send() send data larger than 2GB will be truncated and return None, without exception raised.

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

Hi @kmiku7, it's possible to write tests that use a large amount of memory and 
to run them only when asked to with bigmemtest: 
https://docs.python.org/3/library/test.html#test.support.bigmemtest

There is some tests that use it in the codebase like 
https://github.com/python/cpython/blob/1561703a78849ac3511055590d9d1bd2c62a2072/Lib/test/test_bz2.py#L646-L647

Creating a large string and sending it through a socket should be ok if you 
mark the test with this decorator.

[issue36297] Remove unicode_internal codec

[Inada Naoki]

Inada Naoki  added the comment:

I tried to remove all legacy API and wchar_t cache in unicodeobject.  This is 
experimental branch.
https://github.com/methane/cpython/pull/18/files


I'm thinking about adding configure option to remove them from 3.8.

* It may help people to find third party extensions using legacy API.
* Projects which doesn't use such third party extension can use this option to 
reduce some memory usage (8 byte for all unicode object).

Carl Bordum Hansen  added the comment:

I submitted a PR that addresses this and the next example, which also uses 
print unnecessarily.

To answer your last comment rhettinger; the preceding text tells you /why/ one 
might want to use a staticmethod:

"""
Good candidates for static methods are methods that do not reference the
``self`` variable.

For instance, a statistics package may include a container class for
experimental data.  The class provides normal methods for computing the average,
mean, median, and other descriptive statistics that depend on the data. However,
there may be useful functions which are conceptually related but do not depend
on the data.  For instance, ``erf(x)`` is handy conversion routine that comes up
in statistical work but does not directly depend on a particular dataset.
It can be called either from an object or the class:  ``s.erf(1.5) --> .9332`` 
or
``Sample.erf(1.5) --> .9332``.

Since staticmethods return the underlying function with no changes, the example
calls are unexciting::

[issue35066] Inconsistency between dangling '%' handling in time.strftime() and datetime.strftime()

[Xavier de Gaye]

Xavier de Gaye  added the comment:

The new test added by changeset 454b3d4ea246e8751534e105548d141ed7b0b032 fails 
on Android:

==
FAIL: test_strftime_trailing_percent (test.datetimetester.TestDate_Pure)

AssertionError: '' != '%'
+ %

The implementation of strftime() on Android does not seem to be posix compliant:
>>> import time
>>> time.strftime('A%Q')
'AQ'
>>> time.strftime('%')
''

However the new test is not about testing posix compliance and the following 
patch fixes this test failure on Android while still testing that the changes 
made by this changeset cause a trailing '%' to not raise the exception anymore:

[issue36343] Certificate added to Win Store not available

[Christian Herdtweck]

New submission from Christian Herdtweck :

I have created a self-signed certificate as my fake CA, used it to sign the 
certificate of my test server. I added the fake CA to the client (Windows 7) 
certificate store (System settings > Internet Settings > Content > 
Certificates), imported it there first only to "trusted root certificate 
authorities (translating from German "Vertrauenswürdige 
Stammzertifizierungsstellen" here), after failed tests to all tabs (including 
"own certificates", "intermediate certification authorities", but not the the 
"non-trusted issuers").

I can see my fake ca certificate in the lists in the windows settings, but 
querying the windows CA store through python (version 3.7), either through 
ssl.create_default_context().get_ca_certs() or ssl.enum_certificates(store) for 
store in ("CA", "ROOT", "MY") I only see some default builtin authorities 
(digicert, microsoft, comodo, verisign, etc).

This might be related to https://bugs.python.org/issue36011 . The related PR 
https://github.com/python/cpython/pull/11923 is now closed but I do not see the 
commit in master/3.7/feature-version branch. Was it dismissed?

I am aware there are options to add certificate files to SSL_CERT_DIR, but it 
is my understanding that python now uses the windows certificate store and that 
is where in my case the certificate should go.

[issue30040] Speedup empty dict creation and reduce its memory usage

[Inada Naoki]

Inada Naoki  added the comment:

I merged PR-12307 instead of PR-12308 because:

* PR-12308 adds much code, it makes difficult to maintain dict (I faced many 
SEGV while creating PR-12308)
* PR-12308 is based on PR-12307.  So they are not mutually exclusive.

And I close this issue because there are no more drawbacks about first 
insertion.
If you really hate `ma_keys == Py_EMPTY_KEYS` and prefer `ma_keys == NULL` to 
it, please reopen this issue and PR 12308.  I won't remove empty-dict3 branch 
for a while.

[STINNER Victor]

STINNER Victor  added the comment:

Xavier de Gaye: That's why I asked to stop relying on the exact behavior of 
strftime() of the libc to get portable behavior :-/ See my previous comments.

IMHO the correct fix is to strip trailing % from the format string, call 
strftime() and then concatenate the trailing %.

[issue36236] Python crash on macOS when CWD is invalid

[STINNER Victor]

STINNER Victor  added the comment:

> Omitting it from sys.path in that case makes sense to me, but I'm not sure 
> what sys.argv[0] should be set to.

I propose to use ".". It would be consistent with platforms which doesn't 
implement realpath:

if (have_module_arg) {
#if defined(HAVE_REALPATH) || defined(MS_WINDOWS)
_Py_wgetcwd(fullpath, Py_ARRAY_LENGTH(fullpath));
argv0 = fullpath;
n = wcslen(argv0);
#else
argv0 = L".";
n = 1;
#endif
}

And it defers the error handler to later. Example of Python 3 running in a 
removed directory:

$ python3
Python 3.7.2 (default, Jan 16 2019, 19:49:22) 
>>> import os
>>> os.getcwd()
FileNotFoundError: [Errno 2] No such file or directory

>>> os.path.abspath('.')
Traceback (most recent call last):
  File "/usr/lib64/python3.7/posixpath.py", line 383, in abspath
cwd = os.getcwd()
FileNotFoundError: [Errno 2] No such file or directory

I would prefer "." than "-m".

@rhettinger commented on the removal of the print statement in the method call, 
which was addressed by the creator of that PR.  PR1034 was just waiting for 
final review and approval.

The difference between this and the print in the classmethod example is that 
having to two prints in this example resulted in output of:
  >>> E.f(3)
  3
  >>> print(E.f(3))
  3
  None

whereas the classmethod example doesn't have the issue of printing `None`.

I don't think the second PR is necessary.

[issue36344] install_certificates.command too complicated, copy from pip's dir instead

[Dmitrii Pasechnik]

New submission from Dmitrii Pasechnik :

Currently (e.g. on the released Python 2.7.16) 
Mac/BuildScript/resources/install_certificates.command does install certifi 
module from the net and symlinks its cacert.pem to provide openssl with a 
working certificate. The same task may be accomplished much easier, by 
symlinking pip's cacert.pem, as follows (just shell commands, for the purposes 
of demonstration)

cd local/openssl
rm -f local/openssl/cert.pem
ln -s ../lib/python2.7/site-packages/pip/_vendor/certifi/cacert.pem cert.pem 

This works as pip's cacert.pem contains the same certificate as the one 
provided by unvendored certifi (as can be seen by looking at it using "openssl 
x509 -in ..." on it).

I'd be happy to provide a PR if this is acceptable.

[issue33875] Allow dynamic password evaluation in pypirc configuration file.

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

I think there might be a need for a new function in the getpass module that 
fetch it from the operating system secure enclave, like KeyChain on OSX.

Currently there is no facility for storing secrets securely, the documentation 
of secrets says:

> Applications should not store passwords in a recoverable format, whether 
> plain text or encrypted.

but as far as I know there is no facility to save a secret when you actually 
need to get it back in plaintext.

[issue36085] Enable better DLL resolution

[Łukasz Langa]

Łukasz Langa  added the comment:

Personally I am fine with Python 3.8 dropping Windows 7 support entirely if 
this makes it work better in Windows 8+. However, the 3 month overlap here 
would set a precedent that we don't have to adhere to self-imposed timing 
restrictions which is dangerous territory.

I think it's reasonable to leave Windows 7 support but *require* KB2533625 to 
be in. We've done similar things before on other platforms.

[issue35066] Inconsistency between dangling '%' handling in time.strftime() and datetime.strftime()

[Michael Saah]

Michael Saah  added the comment:

While I agree with Victor that reworking time.strftime to be more portable
is a great idea, this issue was never about that; it was about making
exception throwing behavior consistent across datetime's two strftime
implementations (python and C), and also bringing them into line with what
time.strftime does.

Xavier's bug shows that my test methodology didn't take into account the
range of libc strftime behavior. The patch proposed makes sense to me.

[issue35066] Inconsistency between dangling '%' handling in time.strftime() and datetime.strftime()

[Paul Ganssle]

Paul Ganssle  added the comment:

I think the proposed change to the test will work, or we can mark the test as 
an expected failure on Android (on the theory that the test *should* work 
because we want the behavior normalized, but we are not living up to that).

In either case, I think a separate issue for normalizing the behavior of 
`strftime` across platforms would be good. I agree with Victor that the 
inconsistencies in libc are not a great experience for our users.

[Paul Ganssle]

Paul Ganssle  added the comment:

> No please, don't do that :-(

Interesting, I don't feel terribly strongly about it, but I would have thought 
that you'd be more in favor of that solution, maybe we have a different 
definition of "expected failure"?

Usually in my projects, I use xfail if I have *tests* for a bug, but no fix for 
it yet. The xfail-ing test serves two purposes: 1. it notifies me if the bug is 
incidentally fixed (so that I can remove the xfail and it becomes a regression 
test, and I close the bug report) and 2. it allows me to encode acceptance 
criteria for fixing the bug directly into the test suite.

I do personally like the idea of separate tests for "is this consistent across 
platforms" and "does this throw an error", but it is true that once it's 
possible to pass the consistency test it *also* serves as a test that no errors 
are thrown.

Most computers have at least 4 GB of memory. It would be possible to write a 
"bigmem" test which build a string longer than 2 GiB, send it and check the 
received length, but I'm not sure that it's worth it: there is no such test in 
the master branch.

[issue36346] Prepare for removing the legacy Unicode C API

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

The legacy Unicode C API was deprecated in 3.3. Its support consumes resources: 
more memory usage by Unicode objects, additional code for handling Unicode 
objects created with the legacy C API. Currently every Unicode object has a 
cache for the wchar_t representation.

The proposed PR adds two compile time options: HAVE_UNICODE_WCHAR_CACHE and 
USE_UNICODE_WCHAR_CACHE. Both are set to 1 by default.

If USE_UNICODE_WCHAR_CACHE is set to 0, CPython will not use the wchar_t cache 
internally. The new wchar_t based C API will be used instead of the Py_UNICODE 
based C API. This can add small performance penalty for creating a temporary 
buffer for the wchar_t representation. On other hand, this will decrease the 
long-term memory usage. This build is binary compatible with the standard build 
and third-party extensions can use the legacy Unicode C API.

If HAVE_UNICODE_WCHAR_CACHE is set to 0, the wchar_t cache will be completely 
removed. The legacy Unicode C API will be not available, and functions that 
need it (e.g. PyArg_ParseTuple() with the "u" format unit) will always fail. 
This build is binary incompatible with the standard build if you use the legacy 
or non-stable Unicode C API.

I hope that these options will help third-party projects to prepare for 
removing the legacy Unicode C API in future.

[issue36318] Adding support for setting the "disabled" attribute of loggers from logging.config.dictConfig

[Vinay Sajip]

Vinay Sajip  added the comment:

> Actually people do this all the time, to deactivate the logging of some 
> third-party libraries (me included).

It would be better to set the level of those loggers to e.g. ERROR or CRITICAL 
rather than disabling them altogether - presumably if something bad happens in 
those packages, one would want to know!

> In addition, all public attributes ... can be set from 
> `logging.config.dictConfig`, except the `disabled` attribute, which is 
> inconsistent.

I don't especially want people to use `disabled` for this type of thing - the 
main reason for having it is that following an on-the-fly reconfiguration in a 
long-running process, some threads might still be active that contain 
references to now-unwanted loggers, and disabling makes those references 
inactive without the need to track them down. I would recommend using e.g. 
CRITICAL as a level for the use case you mention.

[issue36347] Add the constant READWRITE for PyMemberDef

READONLY or `0`.

I would like to add a new constant for `0` and name it `READWRITE`.
