[issue26285] Garbage collection of unused input sections from CPython binaries

[Martin Panter]

Martin Panter added the comment:

Maybe I am missing something, but I don’t see how you could load your module if 
it uses PyMem_RawMalloc. Perhaps PyMem_RawMalloc has been removed from some 
other executable (e.g. Parser/pgen), rather than the main Python executable?

[issue26136] DeprecationWarning for PEP 479 (generator_stop)

[Martin Panter]

Martin Panter added the comment:

Thanks for the updated patch. There are a couple minor problems with the What’s 
New entry, which you can fix if you want, or I could fix if I get around to 
merging it:

* Bullet point should probably be wrapped onto multiple lines
* According to the 3.5 What’s New, the DeprecationWarning is “non-silent”, but 
I would just drop the “silent” attribute (Once upon a time in Python 2, 
DeprecationWarning was apparently enabled by default, in constrast with 
PendingDeprecationWarning, which was silenced by default.)
* Change “which will trigger a RuntimeError” → “and will trigger . . .”
* Missing full stop at the end

[issue25179] PEP 498 f-strings need to be documented

[Martin Panter]

Martin Panter added the comment:

Regarding doc strings, it seems that a constant f-string without any 
interpolations does become a doc string. But I would treat this as an 
implementation detail, not something to advertise.

Attached is my attempt at a patch. Please have a look and let me know if there 
are things I missed, if I added too much detail, wrong terminology, or 
whatever. I haven’t really written documentation like this before.

The combinations and permutations of all the Fr". . ." prefixes are getting 
borderline out of hand in the lexical_analysis.rst grammar. Any suggestions?

I put the bulk of the documentation in a new section “Formatted string 
literals” of the Lexical Analysis chapter, the same place that describes escape 
sequences and raw strings. Let me know if there is a more appropriate place for 
it. It doesn’t feel quite right where it is because this chapter comes before 
Expressions, and f-strings use expressions inside them.

I also made minimal changes to existing parts of the documentation and 
tutorial, to point to the new documentation. Perhaps some code examples could 
be changed from str.format() to f". . .", but I think that would be the subject 
of a separate patch. There are even places that still use the outdated 
"{0}".format() numbering.

[issue26209] TypeError in smtpd module with string arguments

[Lorenzo Ancora]

Lorenzo Ancora added the comment:

(msg259748) ok, then I propose to correct 
https://docs.python.org/dev/library/smtpd.html?highlight=q#smtpd.SMTPServer 
from:

.. class:: SMTPServer(localaddr, remoteaddr, data_size_limit=33554432,\
  map=None, enable_SMTPUTF8=False, decode_data=True)

   Create a new :class:`SMTPServer` object, which binds to local address
   *localaddr*.  It will treat *remoteaddr* as an upstream SMTP relayer.  It
   inherits from :class:`asyncore.dispatcher`, and so will insert itself into
   :mod:`asyncore`'s event loop on instantiation.


To:


.. class:: SMTPServer(localaddr, remoteaddr, data_size_limit=33554432,\
  map=None, enable_SMTPUTF8=False, decode_data=True)

   Creates a new :class:`SMTPServer` object, which binds to local address
   *localaddr* and uses *remoteaddr* as an upstream SMTP relayer.
   Both parameters should be a tuple in the form ``("host", portnumber)``, 
where *host* is a valid IP/FQDN.
   The object will insert itself into :mod:`asyncore`'s event loop on 
instantiation (inherits from :class:`asyncore.dispatcher`) and can be started 
with a call to :class:`asyncore.loop`.

---

These clarifications should be also inserted in the source code as heredocs 
(without the Sphynx syntax).
I really think that those changes will make the use of smtpd easier.

[issue26302] cookies module allows commas in keys

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

_LegalChars contained only characters which don't require quoting, as 
documented in the comment above. If _LegalChars was only used to create 
_is_legal_key, we would just wrote the regular expression. But it is used also 
in other places. In this particular case adding "\" to _LegalChars doesn't lead 
to visible bug (except inconsistency with the comment), but we can't be sure.

_is_legal_key() is implementation detail. It would be better to test public API.

Note that the proposed code change would be a 3.6 only enhancement.  Adding the

module is not deprecated, then a 3.6 code change could be considered.  But only 
a doc change for now.

Terry J. Reedy added the comment:

Code patches should not be assigned to 'docs'.  But Berker, for the reason 
stated, thinks this should be doc only.  Giampaolo is not currently active, so 
should not be assigned the issue by anyone else.

After making a patch -- see the devguide -- use the File: Browse button to 
upload a file.  You can suggest a specific doc change in a message, without a 
.patch or .diff file.

[issue26288] Optimize PyLong_AsDouble for single-digit longs

[Antoine Pitrou]

Antoine Pitrou added the comment:

Actually, let me refine that. nbody and spectral-norm don't make sense
for people running CPython. Perhaps people running PyPy might care about
their performance... (though PyPy is supposed to support a subset of
Numpy too)

Sorry, I was a bit brief: The current comment says "decimal" instead of 
"double". It should be changed to "double".

If spectral-norm and nbody aren't good benchmarks then let's remove them from 
our benchmarks suite.

I'll remove that comment anyways, as it doesn't make a lot of sense :)

> Additionally, "single digit will always fit a double"?

What's wrong about that phrase?  Would this be better: "It's safe to cast a 
single-digit long (31 bits) to double"?

[issue21955] ceval.c: implement fast path for integers with a single digit

[Yury Selivanov]

Yury Selivanov added the comment:

I think this is a random fluctuation, that benchmark (and re lib) doesn't use 
the operators too much.  It can't be THAT slower just because of optimizing a 
few binops.

[issue26303] Shared execution context between doctests in a module

[kernc]

kernc added the comment:

The use case is not unpopular [1] and with unambiguous examples like

>>> arr = np.arange(5)
>>> my_sum(arr)
10

(i.e., without importing numpy as np everywhere), it also makes a lot of sense.

[issue26303] Shared execution context between doctests in a module

[kernc]

New submission from kernc:

The doctest execution context documentation [0] says the tests get shallow 
*copies* of module's globals, so one test can't mingle with results of another. 
This makes it impossible to make literate modules such as:


"""
This module is about reusable doctests context.

Examples

Let's prepare something the later examples can work with:

>>> import foo
>>> result = foo.Something()
2

"""
class Bar:
"""
Class about something.

>>> bar = Bar(foo)
>>> bar.uses(foo)
True

"""
def baz(self):
"""
Returns 3.

>>> result + bar.baz()
5

"""
return 3


I.e. one has to instantiate everything in every single test. The documentation 
says one can pass their own globals as `glob=your_dict`, but it doesn't mention 
the dict is *cleared* after the test run.

Please acknowledge the use case of doctests in a module sharing their 
environment and results sometimes legitimately exists, and to make it 
future-compatible, please amend the final paragraph of the relevant part of 
documentation [0] like so:


You can force use of your own dict as the execution context by 
passing `globs=your_dict` to `testmod()` or `testfile()` instead, 
e.g., to have all doctests in a module use the _same_ execution
context (sharing variables), define a context like so:

class Context(dict):
def copy(self):
return self
def clear(self):
pass

and use it, optionally prepopulated with `M`'s globals:

doctest.testmod(module,
glob=Context(module.__dict__.copy()))


Thank you!

I think TestProgram should be anonymous, all the work is done in its 
constructor. I don't see why would anyone would call its functions. I can

[issue26209] TypeError in smtpd module with string arguments

[Lorenzo Ancora]

Lorenzo Ancora added the comment:

(msg259475) Terry J. Reedy thank you for the correction, I've confused the 
versions affected with the versions actually supported.
Since this doesn't only affect the documentation, is it correct to assign the 
issue to docs@python?
The expert index indicates giampaolo.rodola as the module maintainer, so he 
should be moved from the nosy list to the field "Assigned To" and docs@python 
should be in the nosy list.

Also, there is a documentation on how to send a patch for a specific module in 
Python 3.5?
I'd like to help by creating a new source code patch. :-)

[issue21042] ctypes.util.find_library() should return full pathname instead of filename in linux

[Tamás Bence Gedai]

Tamás Bence Gedai added the comment:

Added a new patch, as Martin pointed out, I put back the ABI matching. The 
regex looks quite ugly, because it has to match \n\t. To be exact, it has to 
match something like this: "/lib/x86_64-linux-gnu/libc.so.6\n\tlibbz2.so.1.0 
(libc6,x86-64)".

I updated the docs, although I don't know what should I write for the version, 
please someone help me with that.

For testing, there's a test function in this module, I updated that.

[issue21955] ceval.c: implement fast path for integers with a single digit

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> I see two main trends: optimize most cases (optimize most operators for int 
> and float,  ex: fastint5_4.patch) versus optimize very few cases to limit

I agree that may be optimizing very few cases is better. We need to collect the 
statistics of using different operations with different types in long run of 
tests or benchmarks. If say division is used 100 times less than addition, we 
shouldn't complicate ceval loop to optimize it.

[issue26300] "unpacked" bytecode

[Andrew Barnert]

Andrew Barnert added the comment:

Reading more about wpython (slide 23 of 
https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/wpython2/Cleanup%20and%20new%20optimizations%20in%20WPython%201.1.pdf),
 one of his optimizations was moving the peephole optimizer into the compiler, 
so it could just use the linked list of block objects of arrays of instruction 
objects, instead of raw bytecode.

Obviously that idea isn't compatible with PEP 511. But on the off chance that 
PEP 511 founders, that might be the simplest answer to this problem.
