[issue14119] Ability to adjust queue size in Executors
Victor Varvariuc added the comment: Maybe I should have created another issue for this, but without this issue being solved, the new issue will not help much.

[issue20160] broken ctypes calling convention on MSVC / 64-bit Windows (large structs)
New submission from Mark Dickinson:
The argument-passing code for passing structs larger than 8 bytes is broken on
64-bit Windows, leading to potential segmentation faults or other unpredictable
behaviour. According to
http://msdn.microsoft.com/en-us/library/zthk2dkh.aspx
structs not of size 1, 2, 4 or 8 bytes should be passed by pointer. ctypes
instead puts sizeof(struct) bytes onto the stack. The offending code is in
ffi_prep_args in /Modules/_ctypes/libffi_msvc/ffi.c, which apparently hasn't
been kept up to date with the /Modules/_ctypes/libffi/src/x86/ffi.c. The
latter module works correctly: it has an extra #ifdef X86_WIN64 block (shown
below) to take care of structs not of size 1, 2, 4 or 8. That block is missing
in the libffi_msvc version.
z = (*p_arg)-size;
#ifdef X86_WIN64
if (z sizeof(ffi_arg)
|| ((*p_arg)-type == FFI_TYPE_STRUCT
(z != 1 z != 2 z != 4 z != 8))
#if FFI_TYPE_DOUBLE != FFI_TYPE_LONGDOUBLE
|| ((*p_arg)-type == FFI_TYPE_LONGDOUBLE)
#endif
)
{
z = sizeof(ffi_arg);
*(void **)argp = *p_argv;
}
else if ((*p_arg)-type == FFI_TYPE_FLOAT)
{
memcpy(argp, *p_argv, z);
}
else
#endif
It looks to me as though issue 17310 may be related.
Credit for this discovery should go to Freek Mank.

[issue20144] Argument Clinic doesn't support named constants as default values
Larry Hastings added the comment:
Here's a second patch; I think this is ready to go in
I cleaned up the node parsing a lot. It now knows how to parse the following
types of default values:
* Number (this applies to both ints and floats)
* String ('hello')
* Attribute (sys.maxsize)
* Named constant (None, True, False)
As long as I'm fixing this, I want to add support for any other values we're
going to want. Did I miss any? Note that we can't really support container
types, because initializing them on the C side isn't practical.
Also, the tests don't exercise all of the above possible node types, just
because I couldn't remember builtins that used those types. We'll fill in the
remaining tests as we port new functions to Argument Clinic.
If I can get a quick LGTM review, I'll check this in.

[issue19723] Argument Clinic should add markers for humans
Larry Hastings added the comment: Antoine just suggested that, if we used this accumulator thing, we'd want a convention for where the generated text should go. I actually have an answer for that: near the end, below the implementations of the module / class methods, but above the methoddef/type structures and the module init function. My reasoning: when I navigate CPython C files implementing a module or a type, when I know what entry point I want I just search for its name. When I don't know what I want, I jump to the end, then scroll up until I find the name in the init function or the structures. So I wouldn't want the code at the very end; that would screw up that navigation mode. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19723 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20141] Argument Clinic: broken support for 'O!'
Larry Hastings added the comment: Attached is a new, simpler approach for supporting O!. The object() converter now takes two arguments: * type, which is the type you want the parameter declared as (e.g. PyUnicodeObject *) * subclass_of, which is the PyTypeObject you want to enforce the value is an instance of (e.g. PyUnicode_Type) The old approach was kind of a lovely idea, but was too complicated, and it would have meant registering any new type (like third-party types). This is less convenient, but simple. And it would lend itself well to making a custom converter if you used it a lot. I'll write some documentation for it now, but I wanted to post the code so I could get a review. p.s. Why was is marked crash and release blocker? That's very inaccurate. And assigned to docs?

[issue20162] Test test_hash_distribution fails on RHEL 6.5 / ppc64
Yury V. Zaytsev added the comment: To check whether the problem is in the _le64toh() macro as suggested by Victor Stinner, I've tried the attached patch and the problem is gone. As it turns out, there actually seem to be two problems: First, HAVE_ENDIAN_H is properly defined, because the correct include file is found, but HAVE_LETOH64 is not defined, even though it exists in the system and is working. Therefore, the macro implementation is used instead. However, the second problem is that apparently something is wrong about the macro, even though Victor says it looks fine on the paper, because when macro is replaced by a function from glibc like in my patch, it works. The solution to the first problem, I guess, is to add a proper check to the configure script. I don't have a solution for the second problem.

Guido, can you live with that? I think it's a slight improvement but I'm not
committed enough to fight about it. I'll change it back if you want it your
way.

[issue20164] Undocumented KeyError from os.path.expanduser
New submission from Chris Adams:
This is a more general version of #10496: os.path.expanduser is documented as
returning the unmodified string if it cannot be expanded
(http://docs.python.org/3/library/os.path.html#os.path.expanduser) but there's
one edge case where this can fail: when running without HOME in the environment:
https://github.com/python/cpython/blob/3.3/Lib/posixpath.py#L259-L263
In this case, pwd.getpwuid is called and although it's not documented as such,
it raises a KeyError anytime the underlying POSIX getpwuid() call fails:
https://github.com/python/cpython/blob/3.3/Modules/pwdmodule.c#L119-L120
Reproducing this deliberately:

[issue20162] Test test_hash_distribution fails on RHEL 6.5 / ppc64
Yury V. Zaytsev added the comment: After lots of fiddling, I can tell you what's wrong with the macro: apparently it's a compiler bug, visible at -O2 and disappearing at -O1. Assembly output is attached, unfortunately, I'm no ppc64 expert, so I can't immediately tell what exactly went wrong. In any case, the first half of the bug (missing check for HAVE_LETOH64) which triggered the second half still seems valid. I think it's not feasible to upgrade the compiler on RHEL 6.5 (unless someone with a subscription wants to have a go), but fixing the first part should avoid the compiler bug altogether. -- Added file: http://bugs.python.org/file33345/le64toh.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20162 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20162] Test test_hash_distribution fails on RHEL 6.5 / ppc64
Serhiy Storchaka added the comment: On platforms where unaligned access is not an issue, gcc produces for memcpy() an optimal binary code equivalent to simple assignment of 32-bit value. Only MSVC produces slow code, but Windows works only on platforms where unaligned access is not an issue. So we can use simple assignment when _MSC_VER is defined and memcpy() in other cases (it is what I was proposed in issue19183 for PY_UHASH_CPY). -- nosy: +serhiy.storchaka ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20162 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20162] Test test_hash_distribution fails on RHEL 6.5 / ppc64
Yury V. Zaytsev added the comment: Hi Christian, Dave says it's not a compiler bug; the code is slightly violating the C standard, and the compiler optimizes based on a strict reading of the rules. If I compile with -O2 and higher (while -O3 is the default for Python, as far as I can understand), the compiler correctly warns me about possible issues; as you can see, the macro itself is not at fault, even. It's just that in my particular (rare) mix of circumstances: being big endian, using the macro instead of the glibc function due to the first part of the bug, etc. it results in miscompilation, and in your case, it remains a warning, but the result still works. I think the clean solutions to this problem are as follows: 1) Do not break strict aliasing (use memcpy() instead or something) 2) Disable strict aliasing based optimizations (-fno-strict-aliasing) In addition, fixing the first part of the bug (wrongly using a macro even if le64toh is available), will mask the second part for me again, but I'm not sure if it will re-surface at some point later or not :) Hope that helps! -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20162 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment: If you ran clinic.py --clean and then not ran clinic.py without --clean, it's *your* fault. And you will noticed this when run make. I have named this option --clean because it is similar to 'make clean' and 'make distclean'. If you want make automatically call clinic.py, lets 'make clinic' create the .clinic file, 'clinic.py --clean' remove it, and 'make' check if this file exists and run 'make clinic' otherwise. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20158 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20164] Undocumented KeyError from os.path.expanduser
Chris Adams added the comment: Other than hoisting the warnings import to the top (PEP-8) that seems entirely reasonable to me. The user report which we got was confusing because it was non-obvious where it came from - a warning or other pointer would have helped the original reporter get an idea as to what was failing earlier. The other two changes I'd suggest would be documentation updates: os.path.expanduser noting that KeyError may be raised when HOME is undefined and pwd.getpwuid fails for the active user pwd.getpwuid noting that KeyErrors will be raised when the underlying POSIX call fails -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20164 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
