[issue26858] setting SO_REUSEPORT fails on android

[Xavier de Gaye]

Xavier de Gaye added the comment:

Running the "Search" button on the tracker with "Components" set as 
"Cross-Build" lists 42 issues (20 in the last year).

I guess using this existing category is fine if the titles' issues are prefixed 
with "android:".

[issue26917] Inconsistency in unicodedata.normalize()?

[Armin Rigo]

New submission from Armin Rigo:

There is an apparent inconsistency in unicodedata.normalize("NFC"), introduced 
with the switch from the Unicode DB 5.1.0 to 5.2.0 (in Python 2.7).  First, 
please note that my knowledge of unicode is limited, so I may be wrong and the 
following behavior might be perfectly correct.

>>> from unicodedata import normalize
>>> print(normalize("NFC", "---\uafb8\u11a7---").encode('utf-8'))
b'---\xea\xbe\xb8\xe1\x86\xa7---'# i.e., the same as the input

>>> print(normalize("NFC", "---\uafb8\u11a7---\U0002f8a1").encode('utf-8'))
b'---\xea\xbe\xb8---\xe3\xa4\xba'

Note how in the second example the initial two-character part is replaced with 
a single character (actually the first of them).  This does not occur in the 
first example.  In Python 2.6, both inputs would be normalized to the 
single-character output.

The new behavior introduced in Python 2.7 is to first do a quick-check on the 
string, and if this `is_normalized()` function returns 1, we know that the 
string should already be normalized and we return it unmodified.  However, the 
example "\uafb8\u11a7" shows a contradictory behavior: it causes both 
is_normalized() to return 1, but actual normalization to change it.  We can see 
in the second example above that if, for an unrelated reason, we force 
is_normalized() to return 0 (by adding some non-normalized character elsewhere 
in the string), then the "\uafb8\u11a7" is changed.

This is a bit unexpected, but I don't know if it is officially correct behavior 
or if the problem is a bug in `is_normalized()`.

[issue26917] Inconsistency in unicodedata.normalize()?

[Armin Rigo]

Armin Rigo added the comment:

Note: the examples can also be written in this clearer way on Python 3:

>>> from unicodedata import normalize
>>> print(ascii(normalize("NFC", "---\uafb8\u11a7---")))
'---\uafb8\u11a7---'

>>> print(ascii(normalize("NFC", "---\uafb8\u11a7---\U0002f8a1")))
'---\uafb8---\u393a'

[issue26904] Difflib quick_ratio() could use Counter()

[Michael Cuthbert]

Michael Cuthbert added the comment:

@wolma -- you're right, that the inplace __iand__ version of Counter is 
substantially faster -- it is still slower than the current code (since it is 
still basically a superset of it).  However, testing shows that it is close 
enough to the current code as to potentially be worth using it, in order to 
avoid the same issue that arose here (a small speed tweak in this code prevents 
it from taking advantage of larger improvements later).

If you think that is worth changing, I can make a new patch that incorporates 
it.  I don't have formal benchmarks on it, but quick tests show a 10% 
regression from the current speedups to using &= instead of the custom 
summation method.

[issue26917] Inconsistency in unicodedata.normalize()?

[STINNER Victor]

STINNER Victor added the comment:

Extract of unicodedata_UCD_normalize_impl():

if (strcmp(form, "NFC") == 0) {
if (is_normalized(self, input, 1, 0)) {
Py_INCREF(input);
return input;
}
return nfc_nfkc(self, input, 0);
}

is_normalized() is true for "\uafb8\u11a7" but false for "\U0002f8a1" (and also 
false for "\uafb8\u11a7\U0002f8a1").

unicodedata.normalize("NFC", "\uafb8\u11a7") returns the string unchanged 
because is_normalized() is true.

unicodedata.normalize("NFD", "\uafb8\u11a7") returns "\u1101\u116e\u11a7": 
U+afb8 is decomposed to {U+1101, U+116e}.

unicodedata.normalize("NFC", unicodedata.normalize("NFD", "\uafb8\u11a7")) 
returns "\uafb8", it's the result of the Hangul Decomposition. {U+1101, U+116e, 
U+11a7} is composed to {U+afb8}.

It may be an issue in the "quickcheck" property of the Python Unicode database. 
Format of this field:

/* The two quickcheck bits at this shift mean 0=Yes, 1=Maybe, 2=No,
   as described in http://unicode.org/reports/tr15/#Annex8. */
quickcheck_mask = 3 << ((nfc ? 4 : 0) + (k ? 2 : 0));

[issue26917] unicodedata.normalize(): bug in Hangul Composition

[STINNER Victor]

STINNER Victor added the comment:

Extract of nfc_nfkc():

  /* Hangul Composition. We don't need to check for 
 pairs, since we always have decomposed data. */
  code = PyUnicode_READ(kind, data, i);
  if (LBase <= code && code < (LBase+LCount) &&
  i + 1 < len &&
  VBase <= PyUnicode_READ(kind, data, i+1) &&
  PyUnicode_READ(kind, data, i+1) <= (VBase+VCount)) {
  int LIndex, VIndex;
  LIndex = code - LBase;
  VIndex = PyUnicode_READ(kind, data, i+1) - VBase;
  code = SBase + (LIndex*VCount+VIndex)*TCount;
  i+=2;
  if (i < len &&
  TBase <= PyUnicode_READ(kind, data, i) &&
  PyUnicode_READ(kind, data, i) <= (TBase+TCount)) {
  code += PyUnicode_READ(kind, data, i)-TBase;
  i++;
  }
  output[o++] = code;
  continue;
  }

With the input string (1101 116e, 11a7), we get:

* LIndex = 1
* VIndex = 13


code = SBase + (LIndex*VCount+VIndex)*TCount + (ch3 - TBase)
= 0xAC00 + (1 * 21 + 13) * 28 + 0
= 0xafb8

Constants:

* LBase = 0x1100, LCount = 19
* VBase = 0x1161, VCount = 21
* TBase = 0x11A7, TCount = 28
* SBase = 0xAC00

The problem is maybe than we used the 3rd character whereas (ch3 - TBase) is 
equal to 0.

[issue26904] Difflib quick_ratio() could use Counter()

[Michael Cuthbert]

Michael Cuthbert added the comment:

Here are the results I obtained along with the test code I used to get the 
results.  The test code also has a "hybrid" code which I did not propose, but 
maybe I should have, which uses the old code for very short (but not 
degenerate) tests and then the new code for larger tests.  It does add code 
complexity however.

Results:

[issue26917] unicodedata.normalize(): bug in Hangul Composition

[Armin Rigo]

Armin Rigo added the comment:

See also 
https://bitbucket.org/pypy/pypy/issues/2289/incorrect-unicode-normalization .  
It seems that you reached the same conclusion than the OP in that issue: the 
problem would really be that normalizing "\uafb8\u11a7" should not drop the 
second character.  Both Python and PyPy do that, but Python adds the 
"is_normalized()" check, so in some cases it returns the correct unmodified 
result.

[issue26923] asyncio.gather drops cancellation

[Johannes Ebke]

New submission from Johannes Ebke:

In a very specific case, asyncio.gather causes a cancel() call on the Task 
waiting on the _GatheringFuture to return a false positive. An example program 
demonstrating this is attached.

The context: asyncio.gather creates a _GatheringFuture with a list of child 
Futures. Each child Future carries a done callback that updates the 
_GatheringFuture, and once the last child done callback is executed, the 
_GatheringFuture sets its result.

The specific situation: When the last child future changes state to done it 
schedules its done callbacks, but does not immediately execute them. If the 
Task waiting on the gather is then cancelled before the last child done 
callback has run, the cancel method in asyncio/tasks.py:578 determines that the 
_GatheringFuture inspects itself and sees that it is not done() yet, and 
proceeds to cancel all child futures - which has no effect, since all of them 
are already done(). It still returns True, so the Tasks thinks all is well, and 
proceeds with its execution.

The behaviour I would expect is that if cancel() is called on the 
_GatheringFuture, and all children return False on cancel(), then 
_GatheringFuture.cancel() should also return False, i.e.:

def cancel(self):
if self.done():
return False
at_least_one_child_cancelled = False
for child in self._children:
if child.cancel():
at_least_one_child_cancelled = True
return at_least_one_child_cancelled

If I replace _GatheringFuture.cancel with the above variant, the bug disappears 
for me.

More context: We hit this bug sporadically in an integration test of aioredis, 
where some timings conspired to make it appear with a chance of about 1 in 10. 
The minimal example calls the cancellation in a done_callback, so that it 
always hits the window. This was not the way the bug was discovered.

[issue26923] asyncio.gather drops cancellation

[STINNER Victor]

STINNER Victor added the comment:

The doc:
https://docs.python.org/dev/library/asyncio-task.html#asyncio.gather
"Cancellation: if the outer Future is cancelled, all children (that have not 
completed yet) are also cancelled. If any child is cancelled, this is treated 
as if it raised CancelledError – the outer Future is not cancelled in this 
case. (This is to prevent the cancellation of one child to cause other children 
to be cancelled.)"

Thank you for providing the relevant documentation link.

I just noticed that it should probably be clarified that in case the outer 
Future is cancelled, and all children that are not already done ignore the 
cancellation (a.k.a. catch the CancelledError), the cancellation of the outer 
Future does not continue.

This is different to the behaviour of asyncio.wait_for, which always raises a 
CancelledError.

test_distutils fails on an android emulator running an x86 system image at API

is not supported.

Łukasz, my proposal was to also update distutils (in all Python versions that 
get bugfixes) to match the Setuptools behavior and Python 2 behavior. I'd still

[issue26876] Extend MSVCCompiler class to respect environment variables

[Steve Dower]

Steve Dower added the comment:

I was thinking more like this:

if DISTUTILS_USE_SDK:
assume PATH is configured
execute os.getenv("CC", "cl.exe") directly
else:
find VS in the registry
execute "cl.exe" etc.

The only change here from the current situation is preferring the CC variable 
in the former case when it is set. When we look up VS in the registry, we know 
what executable we are going to find and overriding them via the environment is 
only going to cause issues/vulnerabilities.

[issue26939] android: test_functools hangs on armv7

[Xavier de Gaye]

Xavier de Gaye added the comment:

The attached test_output.txt file is the corresponding gdb backtrace[1].

Interestingly, all the tests (issues #26938, #26939, #26940 and #26941) that 
hang on arm use sys.setswitchinterval() aggressively.


[1] The backtrace is interleaved with:
  * Python Exception  'utf8' codec can't 
decode byte 0xb8 in posit ion 0: invalid start byte:
that seem to come from libpython, the python that is embeded in gdb to 
pretty-print gdb output
  * ---Type  to continue, or q  to quit---
sorry, had to resort to copy/paste, gdb 'set logging' does not seem to work

[issue26915] Test identity first in membership operation of ItemsView, ValuesView and Sequence in collections.abc

[Josh Rosenberg]

Josh Rosenberg added the comment:

At some point someone really needs to decide if the C layer behavior of 
performing an identity test before full equality checking is something that 
should be emulated at the Python layer or not. The current state seems 
ridiculous, where C containers check identity first simply by using the easier 
RichCompareBool function, while Python containers have to have the 
identity-then-equality check rewritten explicitly, which feels like a DRY 
violation.

Makes it harder for non-CPython implementations too, since they end up either 
not matching CPython behavior, or writing extra code to match the CPython 
quirks.

I have nothing against this patch, but between PyObject_RichCompareBool and the 
various slightly strange behaviors in the argument parsing format codes (which 
leads to silly workarounds like _check_int_field in #20858), I feel like the 
Python code base is getting cluttered with hacks to emulate the hacky C layer.

[issue26929] android: test_strptime fails

[Xavier de Gaye]

Xavier de Gaye added the comment:

GNU libc says:

 ‘%V’
  The ISO 8601:1988 week number as a decimal number (range ‘01’
  through ‘53’).  ISO weeks start with Monday and end with
  Sunday.  Week ‘01’ of a year is the first week which has the
  majority of its days in that year; this is equivalent to the
  week containing the year’s first Thursday, and it is also
  equivalent to the week containing January 4.  Week ‘01’ of a
  year can contain days from the previous year.  The week before
  week ‘01’ of a year is the last week (‘52’ or ‘53’) of the
  previous year even if it contains days from the new year.

  This format was first standardized by POSIX.2-1992 and by
  ISO C99.


So on 1905-1-1, %V should be 52 instead of 53 as printed by android; is this 
the only bug ?

A pretty good test to find such a mistake.
