[issue16594] SocketServer should set SO_REUSEPORT along with SO_REUSEADDR when present

[Andy Zeldis]

New submission from Andy Zeldis:

On BSD (including Mac OS X) SO_REUSEPORT should be specified along with 
SO_REUSEADDR to match behavior on Linux (and possible Windows). This is needed 
to have multiple listeners to a UDP broadcast.

I discovered this when using PyOSC. Attached is an example modified to subclass 
SocketServer with a workaround. It should be possible to start multiple 
instances of this program, all of which will receive messages to a broadcast 
address (eg 255.255.255.255:7110).

This test uses Python 2.7 on OS X (despite the "python3" shebang line from the 
example)

[issue16592] stringlib_bytes_join doesn't raise MemoryError on allocation failure

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> I wonder why I don't see a memory error in Python 3.3 or earlier. Any idea?

See issue #15958. Now join() accept arbitrary buffer objects, which can be 
modified during iteration, and therefore need a temporary list of Py_buffers.

Ah, thanks, but I didn't crash and OOM it, since it has no swap: memory errors 
get raised quickly here :)

[issue16585] surrogateescape broken w/ multibytecodecs' encode

[Walter Dörwald]

Walter Dörwald added the comment:

And returning bytes is documented in PEP 383, as an extension to the PEP 293 
machinery:

"""To convert non-decodable bytes, a new error handler ([2]) "surrogateescape" 
is introduced, which produces these surrogates. On encoding, the error handler 
converts the surrogate back to the corresponding byte. This error handler will 
be used in any API that receives or produces file names, command line 
arguments, or environment variables.

The error handler interface is extended to allow the encode error handler to 
return byte strings immediately, in addition to returning Unicode strings which 
then get encoded again (also see the discussion below)."""

[issue16595] Add resource.prlimit

[Christian Heimes]

New submission from Christian Heimes:

Linux has an additional function to setrlimit and getrlimit which supports to 
query and/or modify resource limits of another process.

http://www.kernel.org/doc/man-pages/online/pages/man2/getrlimit.2.html

The patch implements resource.prlimit(pid, resource[, limits]) on all platforms 
that have a prlimit() function. I haven't included the regenerated configure 
script. You have to run autoreconf in order to test the new function.

[issue12812] libffi does not build with clang on amd64

[koobs]

koobs added the comment:

This is also an issue for clang builds of Python on FreeBSD and results in the 
_ctypes extension failing to compile (See: koobs-freebsd-clang buildbot)

The original mozilla patch (see References below) did not make it into the 
libffi 3.0.11 release, which has already been committed to the Cpython tree 
(see #15194)

Attached here is the original Mozilla patch to configure & configure.ac which I 
have included in a PR submitted to the FreeBSD ports tree for python27

The PR includes test builds with gcc and clang on multiple FreeBSD versions and 
architectures, along with a libffi unit test run with clang 
(http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/171768)

I propose this patch be committed to all branches to re-enable _ctypes 
extension builds with clang.

[issue11908] Weird `slice.stop or sys.maxint`

[Raymond Hettinger]

Raymond Hettinger added the comment:

ysj:  The "equivalent" means "roughly equivalent" not "precisely equivalent".  
The purpose of the code in the docs is to help communicate what islice() is all 
about.  Practicality beats purity in this regard.  I know of no one who has 
ever been mislead by the islice() docs.

I don't really like the proposed patch -- it improves a bit on technical 
accuracy but forgoes readability and still falls short on what stop=None does 
and on which arguments are required.  

That said, I don't really like the current version of the "roughly equivalent 
code either".  It should probably be rewritten completely (no longer using 
slice() and it should show the actual looping logic.  For clarity, it may be 
helpful to split it into two code-equivalents, one for the finite case (where 
stop is specified) and one for the infinite case (where stop is None).  

As it stands, the examples are beating the code equivalent when it comes to 
communicating what islice() does.  I don't want to lengthen the code fragment 
unless it becomes *both* more communicative and more accurate.

When specified, use hashing algorithms that are secure against 
denial-of-service and other known attacks, at the possible expense of 
performance.  When not specified, use whatever hashing algorithms provide the 
most sensible defaults for every-day use (basically hash the way python 
currently hashes).

Secure hashing would apply not just to strings but to numeric and other types 
as well.  This would break the invariant of `x == y implies hash(x) == hash(y)` 
for numeric types that Mark mentioned.  However, that seems like an 
implementation detail that python users shouldn't rely upon.

[issue15955] gzip, bz2, lzma: add option to limit output size

[Nadeem Vawda]

Nadeem Vawda added the comment:

I've tried reimplementing LZMAFile in terms of the decompress_into()
method, and it has ended up not being any faster than the existing
implementation. (It is _slightly_ faster for readinto() with a large
buffer size, but all other cases it was either of equal performance or
significantly slower.)

In addition, decompress_into() is more complicated to work with than I
had expected, so I withdraw my objection to the approach based on
max_length/unconsumed_tail.


> unconsumed_tail should be private hidden attribute, which automatically 
> prepends any consumed data.

I don't think this is a good idea. In order to have predictable memory
usage, the caller will need to ensure that the current input is fully
decompressed before passing in the next block of compressed data. This
can be done more simply with the interface used by zlib. Compare:

while not d.eof:
output = d.decompress(b'', 8192)
if not output:
compressed = f.read(8192)
if not compressed:
raise ValueError('End-of-stream marker not found')
output = d.decompress(compressed, 8192)
# 

with:

# Using zlib's interface
while not d.eof:
compressed = d.unconsumed_tail or f.read(8192)
if not compressed:
raise ValueError('End-of-stream marker not found')
output = d.decompress(compressed, 8192)
# 


A related, but orthogonal proposal: We might want to make unconsumed_tail
a memoryview (provided the input data is know to be immutable), to avoid
creating an unnecessary copy of the data.

[issue11204] re module: strange behaviour of space inside {m, n}

[Matthew Barnett]

Matthew Barnett added the comment:

Interesting.

In my regex module (http://pypi.python.org/pypi/regex) I have:

bool(regex.match(pat, "bb", regex.VERBOSE)) # True
bool(regex.match(pat, "b{1,3}", regex.VERBOSE)) # False

because I thought that when the VERBOSE flag is turned on it should ignore 
whitespace except when it's inside a character class, so "b{1, 3}" would be 
treated as "b{1,3}".

Apparently re has another exception.

Serhiy Storchaka added the comment:

$ echo 'baaa' | grep -o 'b\{1,3\}a'
bbba
$ echo 'baaa' | grep -o 'b\{1, 3\}a'

$ echo 'bbb{1, 3}aa' | LC_ALL=C egrep -o 'b{1, 3}a'
b{1, 3}a

I.e. grep raises error and egrep chooses silent verbatim meaning. I don't know 
what any standards say about this.

[issue16597] close not being called with context manager on IOError when device is full.

[John-John Tedro]

New submission from John-John Tedro:

In 3.2.2 and 3.2.3 on linux64, when running the following code. 

try:
print("Writing to /dev/full")

with open("/dev/full", "w") as f:
 f.write("Write to full device")
except:
print("Catch, file closed?")

Using

strace -e close ~/usr/python3.2.3/bin/python3 test.py
...
Writing to /dev/full
Catch, file closed?
close(3)= 0

The file descriptor being used (3) to attempt writing to /dev/full is not 
closed until the process exits.

I expected this to be closed when leaving the context manager.

[issue16596] Skip stack unwinding when "next", "until" and "return" pdb commands executed

[Andrew Svetlov]

Andrew Svetlov added the comment:

Patch attached.
It modifies "next", "return" and "until" commands behavior when they are 
executed if current debugged function is generator.
1. "next" skips stack unwindind if yield tries to follow it. Now it goes just 
to next executed line.
2. "until" does the same: skips all yields until target is reached.
3. "return" waits to return *from* generator (by explicit or implicit 
StopIteration or GeneratorExit exception) ignoring following yields inside 
generator.

The question is whether re should always treat 'b{1, 3}a' as a literal, even 
with the VERBOSE flag.

I've checked with Perl 5.14.2, and it agrees with re: adding a space _always_ 
makes it a literal, even with the 'x' flag (/b{1, 3}a/x is treated as 
/b\{1,3}a/).

[issue16598] Docs: double newlines printed in some file iteration examples

[Steven Kryskalla]

New submission from Steven Kryskalla:

I heard someone complain about this code appearing in the official 
documentation in a few places:

for line in open("file.txt"):
print(line)

This code will print two newlines.

I went through the current "default" and "2.7" branches and changed the places 
where this occurred to use print(line, end="") for 3.x or "print line," for 2.x.

r80699.patch is for the "default" branch (3.x)
r80694.py27.patch is for the "2.7" branch

[issue16587] Py_Initialize breaks wprintf on Windows

[STINNER Victor]

STINNER Victor added the comment:

_setmode(self->fd, O_BINARY) change was done in Python 3.2: see the issue 
#10841. This change introduced regressions:

 - #11272: "input() has trailing carriage return on windows", fixed in Python 
3.2.1
 - #11395: "print(s) fails on Windows with long strings", fixed in Python 3.2.1
 - #13119: "Newline for print() is \n on Windows, and not \r\n as expected", 
fixed in Python 3.3 (and will be fixed in Python 3.2.4)

In Python 3.1, _setmode(self->fd, O_BINARY) was already used when Python is 
called with the -u command line option.

_setmode() supports different options:

 - _O_BINARY: no conversion
 - _O_TEXT: translate "\n" with "\r\n"
 - _O_U8TEXT: UTF-8 without BOM
 - _O_U16TEXT: UTF-16 without BOM
 - _O_WTEXT: UTF-16 with BOM

I didn't try wprintf(). This function is not used in the Python source code 
(except in the Windows launcher, which is not part of the main interpreter).

I don't know how to fix wprintf().
