[issue28727] Implement comparison (x==y and x!=y) for _sre.SRE_Pattern

[STINNER Victor]

STINNER Victor added the comment:

Patch version 3:

* pattern_hash() includes isbytes, I also shifted flags by 1 bit to not erase 
the isbytes bit (FYI maximum value of flags is 256)
* pattern_richcompare() avoids calling PyObject_RichCompareBool() if flags or 
isbytes is different
* unit test ensures that no BytesWarning warning is raised
* checks hash() in unit tests
* fix also the unit test with a different flag (use the same pattern)
* document also in the unit test that the comparison is case sensitive

[issue28688] Warning -- warnings.filters was modified by test_warnings

[STINNER Victor]

STINNER Victor added the comment:

Ok, let me propose a plan for 3.5, 3.6 and 3.7:

* Remove warnings.filters test on Python 3.5 from regrtest
* Implement comparison for SRE_Pattern in Python 3.6 and 3.7: issue #28727

I consider that the issue #28727 is a minor enhancement and so is still good 
for Python 3.6.

So we avoid the ugly *warnings_key.patch*.

Reminder: this issue only occurs in the Python test suite which explicitly 
reloads modules. It should not occur in the wild.

[Martin Panter]

Martin Panter added the comment:

I didn’t really like adding the _add_filter() special handling in the first 
place, but I went ahead because I couldn’t think of a better way to avoid the 
problem with reloading the warnings modules. So unless anyone can suggest 
anything better, I am okay with your patch (even if you dislike it :).

+return (item[0], _pattern_key(item[1]), item[2], _pattern_key(item[3]))

The key is based on (action, message, category, module). I think you should add 
item[4] (lineno).

[issue28730] __reduce__ not being called in dervied extension class from datetime.datetime

That is because some datetime classes now define __reduce_ex__ instead of

[issue24764] cgi.FieldStorage can't parse multipart part headers with Content-Length and no filename in Content-Disposition

[Bert JW Regeer]

Bert JW Regeer added the comment:

I've uploaded a patchset to bug #2 that fixes this issue by fixing 
make_file, and doesn't cause Python to throw out the content-length information.

It also fixes FieldStorage for when you provide it a non-multipart form 
submission and there is no list in FS.

[issue27777] cgi.FieldStorage can't parse simple body with Content-Length and no Content-Disposition

[Bert JW Regeer]

Bert JW Regeer added the comment:

@berker.peksag:

Attached is a patch with a test case that exercises this issue.

Code path is that read_single() checks if the length is greater than 0, and 
then it reads binary, otherwise it reads it as a single line. This fixes 
make_file so that if self.length is greater than or equal to 0, it opens the 
file in binary mode, this matches the checks that write stuff as binary.

This also undoes the change that was made in 
https://bugs.python.org/issue24764. Fixing this issue fixed that one as well, 
and arguably throwing data away doesn't seem like a good idea.

[issue28723] tkinter, radiobutton, indicatoron=0 has no effect.

[Simon Holland]

Simon Holland added the comment:

FYI, it seems that the Tk team are unable to use cocoa for this
functionality so indicatoron has not worked on OSX for Radiobuttons or
Checkbuttons for over 4 years.

[issue28730] __reduce__ not being called in dervied extension class from datetime.datetime

[Jeff Reback]

New submission from Jeff Reback:

xref to https://github.com/pandas-dev/pandas/issues/14679.

pandas has had a cython extension class to datetime.datetime for quite some 
time. A simple __reduce__ is defined.

def __reduce__(self):
object_state = self.value, self.freq, self.tzinfo
print(object_state)
return (Timestamp, object_state)

In 3.5.2:

Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul  2 2016, 17:52:12) 
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> import pickle
>>> pickle.dumps(pd.Timestamp('20130101'))
(13569984000, None, None)
b'\x80\x03cpandas.tslib\nTimestamp\nq\x00\x8a\x08\x00\x00\xc6\xe8\xda\x06\xd5\x12NN\x87q\x01Rq\x02.'

But in 3.6.03b

Python 3.6.0b3 | packaged by conda-forge | (default, Nov  2 2016, 03:28:12) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.54)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> import pickle
>>> pickle.dumps(pd.Timestamp('20130101'))
b'\x80\x03cpandas.tslib\nTimestamp\nq\x00C\n\x07\xdd\x01\x01\x00\x00\x00\x00\x00\x00q\x01\x85q\x02Rq\x03.'


So it appears __reduce__ is no longer called at all (I tried defining 
__getstate__, __getnewargs__ as well, but to no avail). Instead it looks like 
datetime.datetime.__reduce__ (well a c function is actually called).

Link to the codebase.

[issue28729] Exception from sqlite3 adapter masked by sqlite3.InterfaceError

[Julien Palard]

Julien Palard added the comment:

I missed an occurrence of this "if/else" block, and by changing it, a lot of 
tests are failing, typically:

```==
ERROR: CheckBlob (sqlite3.test.types.SqliteTypeTests)
--
Traceback (most recent call last):
  File "/home/mdk/cpython/Lib/sqlite3/test/types.py", line 72, in CheckBlob
self.cur.execute("insert into test(b) values (?)", (val,))
sqlite3.InterfaceError: Problem in adapter

```

So this "if/else" giving back the unadapted parameter even when need_adapt is 
true is necessary, we'll have to understand why and how we can properly detect 
an adapter failure.

[issue28729] Exception from sqlite3 adapter masked by sqlite3.InterfaceError

[Julien Palard]

Julien Palard added the comment:

Problems looks from `Modules/_sqlite/statement.c`:

```
if (!_need_adapt(current_param)) {
adapted = current_param;
} else {
adapted = pysqlite_microprotocols_adapt(current_param, 
(PyObject*)_PrepareProtocolType, NULL);
if (adapted) {
Py_DECREF(current_param);
} else {
PyErr_Clear();
adapted = current_param;
}
}
```

It has not changed since 2006, since e200ab5b3e (backport from pysqlite2 SVN 
repository).

I read it as "If an parameter needs an adapter, and the adapter fails, that's 
OK, continue with the original (unadapted) parameter.", which looks wrong to 
me, but I may miss something obvious? I tried to set an error instead of 
restoring the `current_param` and the 261 tests went well, but I'm not yet 
aware of the coverage of adapters in tests.

[issue28724] Add method send_io, recv_io to the socket module.

[Julien Palard]

Julien Palard added the comment:

Hi, thanks for your contribution!

Documentation give examples implementation of your methods:

 - https://docs.python.org/3/library/socket.html#socket.socket.sendmsg 
 - https://docs.python.org/3/library/socket.html#socket.socket.recvmsg

and from here, some remarks:

 - Why allowing people to mix fds and file objects? I'm not a fan of this: I 
prefer the clarity of allowing only file descriptors. Have you seen such 
methods (allowing both fd and file obj) in the stdlib?
 - The documented implementation for recv_io checks for integer truncation, 
there may be a good reason, should'n you do the same?
 - The documented implementation allows to pass a message, shouldn't you at 
least allow for an optional message to be passed?

Adding those methods may make sense if people are copying send_fds/recv_fds in 
their code, but I found only two copy/paste in github, so I think the best is 
to put your code as a module on pypi and see, from here, if it gets popular?

You should also write a few tests, and comply to the PEP8 (your two methods 
should probably be separated by a newline).

Bests

That's why I say even myself don't like it. To solve an edge case some long 
introduced codes have to been changed. Sigh.

I think you mean your patch. But how does it solve the reentrant problem? Yeah, 
actually it's not reentrant. If the problematic job is not the first job with 
id 0, then the exception won't be set.

With your patch, repeatedly execute print(list(pool.imap(str, gen(. Only 
the first time there is an exception.

[issue28699] Imap from ThreadPool behaves unexpectedly

[Davin Potts]

Davin Potts added the comment:

@xiang.zhang: Your patch looks to be introducing a number of changes to the 
structure of the data being passed around between threads and even 
monitored/indirectly shared across processes.  It's looking increasingly high 
risk to me.

We already have logic for handling exceptions arising during jobs but the one 
situation overlooked in this logic is if the exception occurs "quickly in an 
unfortunate order", meaning the exception is encountered and reported before 
any of the other individual tasks can complete and respond with a result.  This 
oversight of logic can be addressed a couple of ways:
1.  Add a flag to our IMapIterator to indicate when any exception is 
encountered.
2.  Modify the tuples / data structures being maintained across IMapIterator's 
_cache, _items, _unsorted, _index, and _length.
3.  Under relevant conditions, check both _items and _unsorted (not only 
_items) before declaring that we truly have all results in.

I regard option 1 as being potentially a bit fragile and option 2 as 
introducing non-trivial complexity and risk.  With option 3, there's 
effectively no risk and no measurable cost getting to the truth of what has 
actually happened.

[issue28708] Low FD_SETSIZE limit on Windows

[Antoine Pitrou]

Antoine Pitrou added the comment:

> To implement an efficient event loop, IOCP is the way to do: the asyncio 
> module supports it using ProactorEventLoop.

Not everyone uses asyncio, though, so it would still be nice to see the 
select() limit raised anyway.

Implementing your own event loop using IOCP is a hard exercise, much harder 
than getting something to work with select().

[issue28725] Awaiting an awaitable returned from an async function does nothing

[Yury Selivanov]

Yury Selivanov added the comment:

This isn't a bug.  Python doesn't magically unwind awaitables, you have to do 
that yourself:

  async def two():
  await (await one())

Broadly speaking, returning awaitables from coroutines is an anti-pattern.

Closing this one. Feel free to re-open or ask questions :)

[issue28726] py.exe launches wrong version

[Steve Dower]

Steve Dower added the comment:

Were Python 3.5 and 3.4 installed into the same location? That would explain 
some of the problems. It looks like it's finding it from the 3.4 key and then 
skipping the 3.5 key because the path is the same - hence "py -3.5" doesn't 
find it.

Also, we apparently are lacking some Unicode support in the launcher :)

If you delete all of the PythonCore keys and run repair installs for the 
versions of Python you want, that will restore the ones you need. Our installer 
deliberately does not remove anything in site-packages (except for pip, and 
only if it were installed by our installer).

It seems, there are old registry keys which were not deleted by installer. 

HKEY_CURRENT_USER\Software\Python\PythonCore - contains 2.7 and invalid 3.4 
(with "modules" subkey only)

HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore - contains 2.7 (modules only), 
3.4 and 3.5.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore - contains 2.7 and 
3.4 (modules only).

Quiet messy. How can I clean my registry without reinstalling site packages?

[issue28712] Non-Windows mappings for a couple of Windows code pages

[Eryk Sun]

Eryk Sun added the comment:

Thanks, Serihy. When I looked at this previously, I mistakenly assumed that any 
undefined codes would be decoded using the codepage's default Unicode 
character. But for single-byte codepages in the range above 0x9F, Windows 
instead maps undefined codes to the Private Use Area (PUA). For example, using 
decode() from above:

ERROR_NO_UNICODE_TRANSLATION = 0x0459
codepages = 857, 864, 874, 1253, 1255, 1257
for cp in codepages:
undefined = []
for i in range(256):
b = bytes([i])
try:
decode(cp, b)
except OSError as e:
if e.winerror == ERROR_NO_UNICODE_TRANSLATION:
c = decode(cp, b, False)
undefined.append('{:02x}=>{:04x}'.format(ord(b), ord(c)))
print(cp, *undefined, sep=', ')

output:

857, d5=>f8bb, e7=>f8bc, f2=>f8bd
864, a6=>f8be, a7=>f8bf, ff=>f8c0
874, db=>f8c1, dc=>f8c2, dd=>f8c3, de=>f8c4, fc=>f8c5, fd=>f8c6, 
fe=>f8c7, ff=>f8c8
1253, aa=>f8f9, d2=>f8fa, ff=>f8fb
1255, d9=>f88d, da=>f88e, db=>f88f, dc=>f890, dd=>f891, de=>f892, 
df=>f893, fb=>f894, fc=>f895, ff=>f896
1257, a1=>f8fc, a5=>f8fd

Do you think Python's 'replace' handler should prevent adding the 
MB_ERR_INVALID_CHARS flag for PyUnicode_DecodeCodePageStateful? One benefit is 
that the PUA code can be encoded back to the original byte value:

>>> codecs.code_page_encode(1257, '\uf8fd')
(b'\xa5', 1)

> cp932: 0xA0, 0xFD, 0xFE, 0xFF are errors instead of mapping to U+F8F0-U+F8F3.

Windows maps these byte values to PUA codes if the MB_ERR_INVALID_CHARS flag 
isn't used:

>>> decode(932, b'\xa0\xfd\xfe\xff', False)
'\uf8f0\uf8f1\uf8f2\uf8f3'

[issue28727] Implement comparison (x==y and x!=y) for _sre.SRE_Pattern

[STINNER Victor]

New submission from STINNER Victor:

Attached patch implements rich comparison for _sre.SRE_Pattern objects created 
by re.compile().

Comparison between patterns is used in the warnings module to not add 
duplicated filters, see issue #18383:

New changeset f57f4e33ba5e by Martin Panter in branch '3.5':
Issue #18383: Avoid adding duplicate filters when warnings is reloaded
https://hg.python.org/cpython/rev/f57f4e33ba5e

For the warnings module, it became a problem in test_warnings since the Python 
test runner started to clear all caches. When re.purge() is called, 
re.compile() creates a new object, whereas with the cache it returns the same 
object and so the two patterns are equal since it's the same object. => see 
issue #28688

[issue28725] Awaiting an awaitable returned from an async function does nothing

[Gavin Panella]

New submission from Gavin Panella:

The following will sleep:

  async def one():
  await asyncio.sleep(10)

  async def two():
  await one()

  loop.run_until_complete(two())

but the following will not:

  async def one():
  return asyncio.sleep(10)

  async def two():
  await one()

  loop.run_until_complete(two())

I would expect run_until_complete to keep bouncing awaitable results back into 
the event-loop until a non-awaitable is returned. In my code I work around this 
with:

  result = loop.run_until_complete(...)
  while inspect.isawaitable(result):
  result = loop.run_until_complete(result)

I would also expect that the await in `two` would have DTRT with the returned 
generator/coroutine.

[issue28688] Warning -- warnings.filters was modified by test_warnings

[STINNER Victor]

STINNER Victor added the comment:

Hum, this issue is a regression caused by the issue #23839. The environment 
warning was already fixed by the issue #18383 (duplicate: issue #26742):

New changeset f57f4e33ba5e by Martin Panter in branch '3.5':
Issue #18383: Avoid adding duplicate filters when warnings is reloaded
https://hg.python.org/cpython/rev/f57f4e33ba5e

The problem is that _sre.SRE_Pattern doesn't import rich compare: so two 
patterns are only equal if it's exactly the same object... which is likely when 
re caches the compiled expression... But the Python test runner now starts by 
clearing the re cache!

I see different options:

* Find something else to not re-initialize warning filters, 
"_processoptions(sys.warnoptions)" in warnings.py.
* Fix warnings._add_filter() to implement a custom comparator operator for 
regular expression objects: compare pattern and flags
* Implement comparision in _sre.SRE_Pattern

[issue28696] imap from ThreadPool hangs by an exception in a generator function

[Xiang Zhang]

Xiang Zhang added the comment:

In Py3.6, it raises error:

>>> next((pool.imap(str, gen(
Traceback (most recent call last):
  File "/opt/lib/python3.7/multiprocessing/pool.py", line 684, in next
item = self._items.popleft()
IndexError: pop from an empty deque

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/lib/python3.7/multiprocessing/pool.py", line 690, in next
item = self._items.popleft()
IndexError: pop from an empty deque

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "", line 1, in 
  File "/opt/lib/python3.7/multiprocessing/pool.py", line 693, in next
raise StopIteration
StopIteration

But this doesn't looks good. I think it should raise TypeError. It can be fixed 
in #28699.

[issue7659] Attribute assignment on object() instances raises wrong exception

[Pascal Chambon]

Pascal Chambon added the comment:

I guess it can, since retrocompatibility prevents some normalization here.

Or is it worth updating the doc about "AttributeError", misleading regarding 
the type of exception expected in this case ?

[issue28699] Imap from ThreadPool behaves unexpectedly

[Xiang Zhang]

Hi Davin, could it be fixed like this?

 except Exception as ex:
 job, ind = task[:2] if task else (0, 0)
 if job in cache:
-cache[job]._set(ind + 1, (False, ex))
+cache[job]._set(ind + 1 if task else 0, (False, ex))
 if set_length:
 util.debug('doing set_length()')
 set_length(i+1)

It seems to me the bug is _handle_tasks doesn't treat the exception correctly 
if it's on the very first. Every time it _set(ind + 1) since if there is any 
exception the task is the previous task and + 1 is needed. But if the exception 
occurs at the very first, task is None and the + 1 is not needed.

I am not very sure but the reported cases work correctly now:

list(Pool(processes=2).imap(double, get_numbers()))  # raises error now
list(pool.imap(str, gen()))  # raises error now

[issue28712] Non-Windows mappings for a couple of Windows code pages

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Thank you Eryk. That is what I want. I just missed that code_page_decode() 
returns a tuple.

Seems Windows maps undefined codes to Unicode characters if they are in the 
range 0x80-0x9f and makes an error if they are outside of this range. But if 
the code starts multibyte sequence, the single byte is an error even if it is 
in the range 0x80-0x9f (codepages 932, 949, 950).

This could be emulated by either decoding with errors='surrogateescape' and 
postprocessing the result (replace '\udc80'-'\udc9f' with '\x80'-'\x9f' and 
handle '\udca0'-'\udcff' as error) or writing custom error handler that does 
the job (but perhaps needed several error handlers corresponding 'strict', 
'replace', 'ignore', etc). Adding a new codec of cause is an option too.

There are few other minor differences between Python and Windows:

cp864: On Windows 0x25 is mapped to '%' (U+0025) instead of '٪' (U+066A).
cp932: 0xA0, 0xFD, 0xFE, 0xFF are errors instead of mapping to U+F8F0-U+F8F3.
cp1255: 0xCA is mapped to U+05BA instead of be undefined.

The first two differences can be handled by postprocessing, the latter needs 
changing the codec.
