[issue32075] Expose ZipImporter Type Object in the include header files.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

There is a plan of reimplementing zipimport in Python (see issue25711). What 
are you going to do with this?

I think that C extensions should use a common import API.

[issue32075] Expose ZipImporter Type Object in the include header files.

[Decorater]

Decorater  added the comment:

That is true, but Well, I am using this in a project of mine currently where it 
loads up encrypted scripts from a zip file. However I must have the import hook 
itself be in an C extension and subclass the current zipimporter. However 
knowing a rewrite for it is best, I have not experienced any bugs with it so 
far actually.

[Decorater]

Decorater  added the comment:

Well since issue25711 might be for 3.7 and newer I guess this patch might 
actually be for 3.6.4 or something then. And then the rewrite would take over 
on 3.7 and newer depending on if the rewrite makes it in to 3.7.

[issue32082] atexit module: allow getting/setting list of handlers directly

[Erik Bray]

New submission from Erik Bray :

In Python 2 it was possible to directly manipulate the list of registered 
atexit handlers through atexit._exithandlers.  Obviously I'm not complaining 
that this went away, as it was an underscored attribute.  But this possibility 
was still useful in the context of testing.

For example, we have a test suite that runs many test cases in subprocesses run 
with multiprocessing.Process.  Since these call os._exit() any atexit handlers 
registered by the code under test are not run.  It's useful, however, to test 
that either

a) Expected atexit handlers ran correctly or
b) No unexpected atexit handlers were registered

To this end we would save and clear atexit._exithandlers, call 
atexit._run_exitfuncs(), then restore the original atexit._exithandlers.

This is not possible on Python 3 since that all lives in the C module state for 
sub-interpreter support.  For the time being it was necessary to work around 
this with a Cython module, but coding around internal extension module 
structures is hardly ideal: 
https://git.sagemath.org/sage.git/diff/src/sage/misc/_context_py3.pyx?id=85b17201255e9919eaa7b5cff367e8bc271c2a3f

I think it would be useful--for testing purposes *only*--to add a 
_get_exitfuncs() function that returns a tuple of the registered handlers, and 
likewise a _set_exitfuncs(handlers) with sets the registered handlers from an 
iterable (the latter being little more than a shortcut for `atexit._clear(); 
for h in handlers: atexit.register(*h)`).

I would propose that these be undocumented internal functions to emphasize that 
they are not how the module should be used in normal circumstances.  At the 
same time it might be worth addressing https://bugs.python.org/issue22867  I 
can provide a patch if this idea is acceptable.

[issue32083] sqlite3 Cursor.description can't return column types

[Katsuhiko YOSHIDA]

New submission from Katsuhiko YOSHIDA :

My schema of sqlite3 table is the following.

--- schema check start ---
% sqlite3 sample.db
SQLite version 3.16.0 2016-11-04 19:09:39
Enter ".help" for usage hints.
sqlite> PRAGMA table_info(Employees);
0|EmployeeID|int|1||1
1|LastName|varchar(20)|1||0
2|FirstName|varchar(10)|1||0

(ommiting)

sqlite>
--- schema check end ---

Then, I tried to output column types by calling Cursor.description. Like this.

--- sample code start ---
import sqlite3

con = sqlite3.connect("sample.db", detect_types=sqlite3.PARSE_DECLTYPES)
cursor = con.cursor()
cursor.execute("select LastName, FirstName from Employees limit 1;")
print cursor.description
cursor.close()
con.close()
--- sample code end ---

The output is the following.

(('LastName', None, None, None, None, None, None), ('FirstName', None, None, 
None, None, None, None))

When changing detect_types parameter to

detect_types=sqlite3.PARSE_DECLTYPES|sqlite3.PARSE_COLNAMES

the result is same.

I expect to output a column type in second element. Could you tell me why?

[issue32084] [Security] http.server can be abused to redirect to (almost) arbitrary URL

[STINNER Victor]

New submission from STINNER Victor :

iDer reported a vulnerability in the HTTP server.

(1) Start a local HTTP server (listen to tcp/8000):

python3 -m http.server 8000

(2) Open a web browser and to go:

http://localhost:8000//www.python.org/%2f..

=> the browser is redirected to http://www.python.org/%2f../

(on this example, the python.org web server redirects to 
https://www.python.org/%2f../ )


Raw HTTP to see the HTTP redirection using netcat:
---
$ echo -ne "GET //www.python.org/%2f.. HTTP/1.0\n\n" | nc localhost 8000
HTTP/1.0 301 Moved Permanently
Server: SimpleHTTP/0.6 Python/3.6.2
Date: Mon, 20 Nov 2017 13:31:42 GMT
Location: //www.python.org/%2f../
---

The problem is in the SimpleHTTPRequestHandler.send_head() function:

* self.path = '//www.python.org/%2f..'
* translate_path() translates '//www.python.org//..' path to self.directory 
(the current directory by default).
* isdir(self.directory) is True but self.path doesn't send with '/', so 
send_head() creates a HTTP redirection (HTTP 301)
* The redirection URL is '//www.python.org/%2f../'. Extract of the raw HTTP: 
"Location: //www.python.org/%2f../"

The web browsers translates the URL '//www.python.org/%2f../' to 
"http://www.python.org/%2f../";... It surprised me, but ok, it's a fact.

I'm not sure what is the best way to fix this vulnerability without rejecting 
valid HTTP requests.

IMHO the root issue is the redirection URL starting with "//". I would expect 
something like "localhost//". The problem is that I'm not sure that the HTTP 
server knows its own "external" hostname. "localhost" is wrong is the server is 
accessed from the outside. Maybe the server must just fail on that case?


This vulnerabilility was reported to the Python Security Response Team (PSRT) 
at October 18, 2017 (one month ago). Since no obvious fix was found, it was 
decided to make the vulnerability public to get more eyes on it to find a quick 
fix.

Note: I'm not sure that this vulnerability is important, since the redirected 
URL ends with "/%2f../" which should be rejected by any correct HTTP Server 
(say, not the Python builtin "simple" HTTP server...).

 we always set the 'type_code' field described in PEP 249 to None. Setting it

[STINNER Victor]

Extract of send_head():

path = self.translate_path(self.path)
f = None
if os.path.isdir(path):
parts = urllib.parse.urlsplit(self.path)
...

urllib.parse.urlsplit('//www.python.org/%2f..') returns:

SplitResult(scheme='', netloc='www.python.org', path='/%2f..', query='', 
fragment='')

Is urlsplit() the correct function to call here? www.python.org is part of the 
path, not of the netloc.

[issue32087] deprecated-removed directive generates overlapping msgids in .pot files

[KINEBUCHI Tomohiko]

New submission from KINEBUCHI Tomohiko :

When gettext builder is invoked, deprecated-removed directive which is defined 
in Doc/tools/extensions/pyspecific.py generates overlapping msgids in .pot 
files.

For example, the following .rst source (taken from Doc/library/dmb.rst L354)::

   .. deprecated-removed:: 3.6 3.8
  Creating database in ``'r'`` and ``'w'`` modes.  Modifying database in
  ``'r'`` mode.

results to following .pot file entries::

   #: ../../library/dbm.rst:357
   msgid "Deprecated since version 3.6, will be removed in version 3.8: 
Creating database in 'r' and 'w' modes.  Modifying database in 'r' mode."
   msgstr ""

   #: ../../library/dbm.rst:357
   msgid "Creating database in ``'r'`` and ``'w'`` modes.  Modifying database 
in ``'r'`` mode."
   msgstr ""

using the command::

   sphinx-build -E -b gettext -D gettext_compact=0  -w warnings.txt -d 
build/.doctrees . locale/pot


The root cause is deprecated-removed directive constructs inappropriate 
sub-doctree for translation.
First, above .rst source is compiled into following tree structure::

   
 
   
 Deprecated since version 3.6, will be removed in version 3.8:
   
 Creating database in...

and gettext builder picks up paragraph node and the second inline node as 
translation targets.

Expected result is that two inline nodes are picked up as translation targets 
and the paragraph node is not, and expected .pot file entries are such as 
following::

   #: ../../library/dbm.rst:357
   msgid "Deprecated since version 3.6, will be removed in version 3.8:"
   msgstr ""

   #: ../../library/dbm.rst:357
   msgid "Creating database in ``'r'`` and ``'w'`` modes.  Modifying database 
in ``'r'`` mode."
   msgstr ""

[issue32089] In developer mode (-X dev), ResourceWarning is only emited once per line numbers

[STINNER Victor]

New submission from STINNER Victor :

The -X dev mode currently *hides* some ResourceWarning warnings:

$ cat x.py 
def func():
open('/etc/issue')

func()
func()

$ ./python x.py 
x.py:2: ResourceWarning: unclosed file <_io.TextIOWrapper name='/etc/issue' 
mode='r' encoding='UTF-8'>
  open('/etc/issue')
x.py:2: ResourceWarning: unclosed file <_io.TextIOWrapper name='/etc/issue' 
mode='r' encoding='UTF-8'>
  open('/etc/issue')

haypo@selma$ ./python -X dev x.py 
x.py:2: ResourceWarning: unclosed file <_io.TextIOWrapper name='/etc/issue' 
mode='r' encoding='UTF-8'>
  open('/etc/issue')


The problem is that the "-W default" inserted by -X dev overrides the final 
filter on ResourceWarning:

$ ./python -X dev -c 'import warnings, pprint; pprint.pprint(warnings.filters)'
[('default',
  re.compile('', re.IGNORECASE),
  ,
  re.compile(''),
  0),
 ('ignore', None, , None, 0),

 ('ignore', None, , None, 0),

With my PR 4474:

$ ./python -c 'import warnings, pprint; pprint.pprint(warnings.filters)'
[('ignore', None, , None, 0),

BytesWarning is not modified by my PR since this specific warning is controlled 
by the -b option. Example with my PR.

-b option, ignore => default:

$ ./python -b -c 'import warnings, pprint; pprint.pprint(warnings.filters)'
[('default', None, , None, 0),
 ('always', None, , None, 0)]

-bb option, ignore => error:

$ ./python -bb -c 'import warnings, pprint; pprint.pprint(warnings.filters)'
[('error', None, , None, 0),
 ('always', None, , None, 0)]

[issue25711] Rewrite zipimport from scratch

[Decorater]

Decorater  added the comment:

So, after reviewing this it started to make me rethink about the zipimport.py 
file.

So my question is how would that file work if it is an pyc file in python37.zip 
or something just to zipimport other modules? There is got to be some sort of 
low level api that can zip import the zip importer then on the rewrite. Am I 
right?

Maybe the best bet is to wait for bug reports on the C Code and fixup the C 
Code if possible so that way there is no conflicts like the ones I just 
questioned.

[issue31630] math.tan has poor accuracy near pi/2 on OpenBSD and NetBSD

[Tim Peters]

Tim Peters  added the comment:

I have no opinion about any version of xxxBSD, because I've never used one ;-)  
If current versions of those do have this failure, has anyone opened a bug 
report on _their_ tracker(s)?  I've seen no reason yet to imagine these 
failures are a fault in Python.

[issue32092] mock.patch with autospec does not consume self / cls argument

[Claudiu Belu]

New submission from Claudiu Belu :

Currently, the autospec=True argument can be passed to mock.patch, but when 
trying to make assertions on the call and its arguments, it can fail, as it 
expects an instance / class instance reference as the first argument (self / 
cls arguments are not consumed when autospec-ing).

Steps to reproduce:

>>> import mock
>>> from mock.tests import testmock
>>>
>>> with mock.patch.object(testmock.Something, 'meth', autospec=True):
... smth = testmock.Something()
... smth.meth(mock.sentinel.a, mock.sentinel.b, mock.sentinel.c, 
mock.sentinel.d)
... smth.meth.assert_called_once_with(mock.sentinel.a, mock.sentinel.b, 
mock.sentinel.c, mock.sentinel.d)
...

Traceback (most recent call last):
  File "", line 4, in

raise value
AssertionError: Expected call: meth(sentinel.a, sentinel.b, sentinel.c, 
sentinel.d)
Actual call: meth(, 
sentinel.a, sentinel.b, sentinel.c, sentinel.d)

Expected result: no AssertionError.

Just don't do that :-)

Use repr(bytes) if you want the b'...' format:

[issue32022] Python crashes with mutually recursive code

[STINNER Victor]

STINNER Victor  added the comment:

I don't think that we can fix this issue. I suggest to close it as WONTFIX.


> sys.setrecursionlimit(3000)

While Python does its best to catch stack overflow, the C implementation of 
CPython can exhaust the stack memory (8 MB in Linux?) and then crash with a 
"stack overflow".

I suggest to rewrite your algorithm to reduce the maximum stack depth.

Or maybe try to find a way to extend the maximum size of the stack (is it 
possible without rebuilding Python?). See for example RLIMIT_STACK of the 
resource module on Unix.


> On linux x86-64 with python 3.6.3 and python 3.7.0a2+ I get a RecursionError: 
> maximum recursion depth exceeded.

The exact memory usage depends on the Python version and maybe compiler flags. 
We reduce the stack usage in Python 3.7, search for "Stack consumption" in:

[issue32094] _args_from_interpreter_flags() doesn't keep -X options

[Antoine Pitrou]

New submission from Antoine Pitrou :

`subprocess._args_from_interpreter_flags()` is used to control the flags passed 
to child Python processes, for example launched by multiprocessing.  
Unfortunately, not all flags are actually recognized by this function:

$ ./python -X dev

[issue30855] [2.7] test_tk: test_use() of test_tkinter.test_widgets randomly fails with "integer value too large to represent" on with AMD64 Windows8 3.5

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Ah, this is Cygwin!

This is a Tk bug 
(https://core.tcl.tk/tk/tktview?name=5ee8af61e5ef8e233158a43459624f4ecf58a6fe). 
It was fixed, but not completely. The fix doesn't work on Cygwin.

Hmm, no; Cygwin isn't installed on ware-win81-release.

When was the fix made?  2.7 on Windows currently uses 8.5.15, we can bump it up 
to latest 8.5 if that will help.

[issue28009] core logic of uuid.getnode() is broken for AIX - all versions

After a clone of master:
a) _unixdll_getnode is renamed to _unix_getnode
since the function _load_system_functions() still depends on 
find_library() - that always returns None, still not working.
Note also - find_library('uuid') will not work on a standard AIX - as 
the library libuuid.a does not exist, neither have I ever seen a shared 
library with the name libuuid.so.
FYI: Finally, "nm -Ae /usr/lib/libc.a | grep uuid" returns

i.e., there is nothing with uuid_generate in it.

_arp_getnode()
AIX does not return any value for itself.
Neither does Centos, (so I expect RHEL will also not), and my old 
debians do not either.

So, after summary - these three functions still do nothing/do not work 
on AIX 6.1 or AIX 7.1 (cannot test AIX 7.2).

And - as before, netstat -ia - when looking at ':', still returns

01:00:5e:00:00:01

for every interface.

The fix was made 2015-11-09. The tag core-8-5-15 was created 2013-09-16.

I'm not well experienced with fossil and thought that 8.5.15 contains this fix, 
but now I see that this is not true. Yes, updating Tcl/Tk can help.

[issue32071] Add py.test-like "-k" test selection to unittest

[Jonas H.]

Jonas H.  added the comment:

Thanks Antoine. I will need some guidance as to what are the correct places to 
make these changes. I'm not quite sure about the abstractions here (runner, 
loader, suite, case, etc.)

My PoC (see GitHub link in first post) uses a TestSuite subclass. (The subclass 
is only so that it's easier to assess the general implementation approach; I 
guess it should be put into the main class instead.)

Things I'm unsure of:

1) Is suite the correct place for this kind of feature?
2) Is the hardcoded fnmatch-based pattern matcher ok, or do we need a new 
abstraction "NameMatcher"?
3) Is the approach of dynamically wrapping 'skip()' around to-be-skipped test 
cases OK?
4) The try...catch statement around 'test.id()' is needed because there are 
some unit tests (unit tests for the unittest module itself) that check for some 
error cases/error handling in the unittest framework, and crash if we try to 
call '.id()' on them. Please remove the try...catch to see these errors if 
you're interested in the details. Is the check OK like that, or is this a code 
smell?

Thanks
Jonas

[issue32096] Py_DecodeLocale() fails if used before the runtime is initialized.

[Eric Snow]

New submission from Eric Snow :

(see the python-dev thread [1])
(related: issue #32086)

When I consolidated the global runtime state into a single global, _PyRuntime, 
calls Py_DecodeLocale() started to break if the runtime hadn't been intialized 
yet.  This is because that function relies on PyMem_RawMalloc() and 
PyMem_RawFree(), which rely on the raw allocator having been initialized as 
part of the runtime (it used to be intialized statically).

The documentation for various "Process-wide parameters" [2] explicitly directs 
users to call Py_DecodeLocale() where necessary.  The docs for 
Py_DecodeLocale(), in turn, explicitly refer to calling PyMem_RawFree().  So 
changing the pre-runtime-init behavior of Py_DecodeLocale() and PyMem_RawFree() 
is a regression that should be fixed.

[issue32095] AIX: ModuleNotFoundError: No module named '_ctypes' - make install fails

[Michael Felt]

Michael Felt  added the comment:

no. I'll install what I have atm.

Too bad - as now it will have an install dependency.

re: https://bugs.python.org/issue27976#msg274628 -- seems a warning that libffi 
is not available might be useful after all.

Question: is ffi still bundled for Darwin - even in 3.7? If yes, maybe it 
should also be bundled for AIX.

In any case, just installing a libffi.a library fixed the install (i.e., make; 
make install)

[issue32071] Add py.test-like "-k" test selection to unittest

[Antoine Pitrou]

Antoine Pitrou  added the comment:

First, I should clarify that I'm not a unittest maintainer.  However, as far as 
I can tell, the maintainers have not been very active lately.  Also, this is a 
reasonably simple enhancement (at least conceptually), so I think can do 
without a maintainer's formal approval.

To your questions:

> 1) Is suite the correct place for this kind of feature?

At its core, TestSuite is really a glorified collection of tests.  The 
selection logic is inside the TestLoader, and indeed the TestLoader docstring 
says:

"""This class is responsible for loading tests according to various criteria 
and returning them wrapped in a TestSuite"""

So I would recommend putting this in TestLoader.

> 2) Is the hardcoded fnmatch-based pattern matcher ok, or do we need a new 
> abstraction "NameMatcher"?

I think the hardcoded approach is ok.  Though to benefit readability you may 
want to use a predicate function instead.

> 3) Is the approach of dynamically wrapping 'skip()' around to-be-skipped test 
> cases OK?

I think this is the wrong approach.  A test that isn't selected shouldn't be 
skipped, it should not appear in the output at all.  Another reason for putting 
this in TestLoader :-)

> 4) The try...catch statement around 'test.id()' is needed because there are 
> some unit tests (unit tests for the unittest module itself) that check for

I'd ask the question differently: do you need to call .id() to do the matching 
at all?  Intuitively, the TestLoader probably knows about the test names 
already, even before it instantiates TestCases for them.  TestCases shouldn't 
be instantiated for tests that are not selected.

[issue32071] Add py.test-like "-k" test selection to unittest

My first implementation actually was mostly the test loader. Two things made me 
change my mind and try to make the changes in the suite code:

- The loader code really only deals with loading (i.e., finding + importing) 
tests. Yes it expects a file pattern like "test*.py" for identifying test case 
files. But apart from that it didn't "feel" right to put name based selection 
there.
- In py.test you'll get a console output like "5 tests passed, 1 test failed, 
12 tests deselected". We can't get anything similar without making bigger 
changes to the test loader, runner, etc. code. Using skip() we at least have 
some info on "skipped" tests, although they're technically not skipped.

Are you still saying this should go to the test loader?

Take a look at TestLoader.loadTestsFromName().  It does much more than
look up test files, it can also look up individual classes or methods.

> - In py.test you'll get a console output like "5 tests passed, 1 test failed,

I'm not sure what the point of displaying the number of "deselected"
tests is: that information doesn't sound very useful in itself.

But in any case, marking them skipped feels wrong to me.  Most often,
skipping a test is an indication that the current system is not fit to
run it (such as not enough RAM, or lacking a third-party library, or
being the wrong OS entirely).

> Are you still saying this should go to the test loader?

IMHO, yes.  Looking at your posted implementation, at least I don't
think TestSuite is the place for it.

STINNER Victor  added the comment:

The internal Python test runner "regrtest" already implements the feature as 
the -m MATCH option and --matchfile FILENAME option. It's implemented in 
test.support._match_file().

See bpo-31324 for a recent issue on this feature: performance issue (it's going 
to be fixed).

[issue32099] Use range in itertools roundrobin recipe

[Terry J. Reedy]

New submission from Terry J. Reedy :

The itertools roundrobin recipe has an outer loop executed a preset number of 
times.  It is currently implemented with two assignments and a while loop.
https://docs.python.org/3/library/itertools.html#itertools-recipes
These can be replaced with a for loop using a reversed range.

def roundrobin(*iterables):
"roundrobin('ABC', 'D', 'EF') --> A D E B F C"
nexts = cycle(iter(it).__next__ for it in iterables)
for current_len in reversed(range(1, len(iterables)+1)):
try:
for next in nexts:
yield next()
except StopIteration:
nexts = cycle(islice(nexts, current_len - 1))

I think this is easier to understand.  So do some other participants in the 
current python-ideas thread 'Rewriting the "roundrobin" recipe in the itertools 
documentation'.

I changed 'pending' to 'current_len' because, to me, 'pending' should be the 
set of iter_nexts and not their number.

I originally avoided the '-1' in the islice call by decrementing both range 
arguments by 1 and calling the loop variable 'reduced_len'.  But having the 
loop variable be the size of the nexts iterable in the next outer iteration 
seemed confusing and not worth the trivial efficiency gain.

An independent change would be to replace 'next' with 'iter' on the basis that 
reusing the builtin name is not good and because 'nexts' is awkward to 
pronounce.

I will produce a PR if any version is preferred to the current one.
---

The OP proposed, and some participants like, an accept-reject algorithm based 
on zip_longest.

def roundrobin(*iters):
"roundrobin('ABC', 'D', 'EF') --> A D E B F C"
# Perhaps "flat_zip_nofill" is a better name, or something similar
sentinel = object()
for tup in it.zip_longest(*iters, fillvalue=sentinel):
yield from (x for x in tup if x is not sentinel)

I dislike creating tuples we don't want, with values we don't want, with an 
arbitrarily small acceptance ratio.  I also note that zip_longest is properly 
used in grouper, whereas roundrobin is the only recipe using cycle.
