[issue27350] Compact and ordered dict

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> How to support sizeof(Py_ssize_t) == 4?

#if SIZEOF_VOID_P == 4

> Can I use int8_t, int16_t and int32_t

You can use PY_INT32_T for 32-bit signed integers, short for 16-bit signed 
integers (if SIZEOF_SHORT == 2) and signed char for 8-bit signed integers. Or 
introduce PY_INT16_T and PY_INT8_T similarly as it was done for PY_INT32_T.

[issue19756] test_nntplib: sporadic failures, network isses? server down?

[Martin Panter]

Martin Panter added the comment:

Here is a patch that changes all affected tests to use a custom server running 
on localhost:

* Local server is based on the existing NNTPv2Handler class, and the 
LocalServerTests class
* Reintegrate test_starttls() back into NetworkedNNTPTestsMixin
* Only test_with_statement() talks to the remote NNTP_HOST now (not affected by 
this bug)
* Make tests in NetworkedNNTPTestsMixin stricter, because the server responses 
are predetermined now
* Add mock comp.lang.python support to NNTPv1Handler.handle_GROUP()
* Add support for rejecting passwords in NNTPv1Handler.handle_AUTHINFO()
* New message number with non-UTF-8 message body for ARTICLE, HEAD, BODY, and 
non-UTF-8 subject for OVER, XOVER

[issue27351] Unexpected ConfigParser.read() behavior when passed fileobject

[Rich Rauenzahn]

Rich Rauenzahn added the comment:

Given that write() accepts a fileobject, but read() accepts a list of strings 
or a string (and readfp() is the one that accepts a fileobject instead), this 
seems like it could be a common enough error that just iterating over the 
fileobject could be undesirable and an exception might be thrown instead.

I'm throwing this out here to see if the library maintainers were aware of this 
odd edge case.

[issue27351] Unexpected ConfigParser.read() behavior when passed fileobject

[Xiang Zhang]

Xiang Zhang added the comment:

The doc tells ConfigParser.read accepts a filename or a list of filenames. Why 
do you pass it fileobject? If you want to use fileobject, why not read_file?

[issue27351] Unexpected ConfigParser.read() behavior when passed fileobject

[Rich Rauenzahn]

New submission from Rich Rauenzahn:

This came up on StackOverflow: http://stackoverflow.com/a/37903779/2077386

I wanted to bring it to your attention in case it hasn't been notice before.

It turns out that if you pass a fileobject (i.e., 
ConfigParser().read(open("foo"))) ConfigParser.read() will look at the 
argument, see it isn't a basestring, and then will iterate over it.  
fileobjects are iterables.

This results in iterating over the contents of the file 'foo'.  It then 
attempts to open a file named after every line read from 'foo'.

For example, I made a file foo and filled it with a-g, each letter per line.  

strace shows:

open("foo", O_RDONLY) = 3
open("a\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("b\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("c\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("d\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("e\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("f\n", O_RDONLY)   = -1 ENOENT (No such file or directory)
open("g\n", O_RDONLY)   = -1 ENOENT (No such file or directory)

...and since the API is designed to ignore files it can't open, it just ignores 
the open errors.

I wonder if this fileobject case ought to be checked for when checking the 
arguments passed into ConfigParser.read().  

Thank you.

[issue23968] rename the platform directory from plat-$(MACHDEP) to plat-$(PLATFORM_TRIPLET)

[Ned Deily]

Ned Deily added the comment:

There is a problem with the current implementation.  When running ./configure 
using compilers other than a current gcc, for example, when using clang or 
older versions of gcc, the build variable MULTIARCH may not get set because 
those compilers do not support --print-multiarch:

configure.ac:744
MULTIARCH=$($CC --print-multiarch 2>/dev/null)

But, a bit later in ./configure, PLATFORM_TRIPLET gets set as a result of 
running conftest.c.  The end result is that PLATFORM_TRIPET is non-empty but 
MULTIARCH is empty.  Still later in configure.ac (around 4477:

if test x$PLATFORM_TRIPLET = x; then
  LIBPL='$(prefix)'"/lib/python${VERSION}/config-${LDVERSION}"
else
  
LIBPL='$(prefix)'"/lib/python${VERSION}/config-${LDVERSION}-${PLATFORM_TRIPLET}"
fi

So, the value of LIBPL is extended to include PLATFORM_TRIPLET regardless of 
whether MULTIARCH has a value.

This causes problems at runtime because get_makefile_filename() in 
Lib/sysconfig.py now uses the value of sys.implemntation's _multiarch attribute 
(whose value is compiled in sysmodule.c from MULTIARCH) to form the path to the 
config directory (the equivalent of LIBPL).  In these cases, sys.implementation 
will have no_multiarch attribute so sysconfig looks for the config directory in 
the pre-3.6 location (e.g. .../lib/python3.6/config-3.6m) even though it was 
installed in the new location (.../lib/python3.6/config-3.6m-darwin).  
Fortunately, both test_sysconfig and test_distutils catch this:

httplib (which is what you are actually calling in your example) does not

[issue24424] xml.dom.minidom: performance issue with Node.insertBefore()

[Robert Haschke]

Robert Haschke added the comment:

Thank you very much for further improving the code. As I understand it, the 
trick is to use temporary variables to minimize access time. Learned something 
new.

I adapted your patch to python 2.7 again. Now, in python3, the new code is even 
faster than the old one (sometimes) for front insertions:

36 time for 1 insertions at front: 0.117563
opt36 time for 1 insertions at front: 0.116014

36 time for 1 insertions at front: 0.114282
opt36 time for 1 insertions at front: 0.116710

old time for 5000 insertions at front: 0.044055
new time for 5000 insertions at front: 0.075433
opt27 time for 5000 insertions at front: 0.052135

old time for 5000 insertions at back: 15.241450
new time for 5000 insertions at back: 0.071004
opt27 time for 5000 insertions at back: 0.046850

I hope you can consider, the patch for python 2.7. There the performance gain 
is most significant.

[issue27346] Implement os.readv() / os.writev()

[Eryk Sun]

Eryk Sun added the comment:

ReadFileScatter and WriteFileGather also require a handle for a file that's 
opened with FILE_FLAG_OVERLAPPED (asynchronous access; the file pointer is not 
updated) and FILE_FLAG_NO_BUFFERING (buffers must be a multiple of the physical 
sector size and aligned to the physical sector size). So Python wouldn't be 
able to use the C runtime's POSIX (low) I/O implementation. ISTM this requires 
resolving issue 12939, with support for overlapped I/O.

[issue25717] tempfile.TemporaryFile fails when dir option set to directory residing on host OS mount

[Martin Panter]

Martin Panter added the comment:

This original bug was about fstat() failing for an anonymous file (after the 
directory entry was removed). But in your situation the file system refuses to 
unlink the directory entry.

If you think there is something that can be fixed in Python, I suggest open a 
new bug. But it seems this is working as documented: “Under Unix, the directory 
entry for the file is removed immediately after the file is created.” In your 
case, this cannot happen, so you get the error from the OS.

[issue22228] Adapt bash readline operate-and-get-next function

[Lele Gaifax]

Lele Gaifax added the comment:

In 
https://github.com/lelit/cpython/commit/3e5e557a876831a99c21f5a173623cb05ff48abf
I reimplemented the functionality in a slightly different and hopefully better
way, rebasing it on current master.

IANAL, but I think that the new approach is different enough from the original
GNU bash code to be considered safe from the license point of view.

I still could not test it against the editline alternative implementation:
AFAICT all the functions and symbols I used are exposed by that library too,
so it may work without resorting to #ifdefs.

In that regards however, I think we could and should take a different approach
in determining which underlying implementation is used: GNU readline >= 4.1
exposes a rl_gnu_readline_p flag that could be used at configure time to
define a IS_GNU_READLINE, and then rely on that to implement different code
paths within the readline.c module.

Please let me know if I should upload a traditional patch, instead of
referencing my branch on github.

As usual, thank you for any review and feedback!

[issue25717] tempfile.TemporaryFile fails when dir option set to directory residing on host OS mount

[issue25717] tempfile.TemporaryFile fails when dir option set to directory residing on host OS mount

[Martin Panter]

Martin Panter added the comment:

Are you sure Oleg? As far as I understand, Python 2 by default wraps C stdio 
file objects, and also has Python 3’s file objects in the “io” module. But I 
expect TemporaryFile() would use the default stdio files, and the cause of this 
bug, Issue 21679, should only have affected the “io” module in 3.5+.

[Марк Коренберг]

New submission from Марк Коренберг:

These functions are not implemented natively in Windows, but
the Windows API has analogous functions ReadFileScatter and WriteFileGather.

[issue19884] Importing readline produces erroneous output

[Martin Panter]

Martin Panter added the comment:

Here is a patch to enable the workaround on OS X, and to adjust the test 
condition to 6.1. It would be nice if someone with OS X and Gnu Readline can 
confirm that this fixes the problem.

[issue19884] Importing readline produces erroneous output

[Martin Panter]

Martin Panter added the comment:

Yogesh: Victor’s patch has already been applied. What is left to do is another 
patch that enables Victor’s code on OS X when Gnu Readline is being used, as 
opposed to the usual Apple Editline.

Also, I think it is valid to update the version check to 6.1. According to 
, enable-meta-key is in 
6.1, but not 6.0. On 6.0 the code probably has no effect.

[issue27345] GzipFile's readinto() reads gzip data instead of file data.

[Ryan Birmingham]

New submission from Ryan Birmingham:

In cases where libraries try to call readinto(), the results are unexpected 
(the gzip data). Shouldn't it instead raise UnsupportedOperation for readinto() 
(and truncate())?
