[issue11877] Change os.fsync() to support physical backing store syncs
Steffen Daode Nurpmeso sdao...@googlemail.com added the comment:
I'll attach 11877.4.diff:
- Docu change (i hope to be better)
- Kept NetBSD after looking into
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/vfs_syscalls.c?rev=1.423content-type=text/x-cvsweb-markuponly_with_tag=MAIN
because fsync_range() with FDISKSYNC set causes a FSYNC_CACHE
flag to be passed through to VOP_FSYNC() in addition to
FSYNC_WAIT, which is what plain fsync() passes exclusively.
(I have not furtherly discovered that. FDISKSYNC was introduced
2005. I believe existence of such a flag will sooner or later
force somebody to make a difference in wether it is set or not.)
- Drop of AIX. According to the systems manual (link in
msg134213) there does not seem to be a difference in between
fsync() and fsync_range()
- Drop of Linux sync_file_range() (see messages above).
By the way, does Linux still require

[issue11849] glibc allocator doesn't release all free()ed memory
Charles-Francois Natali neolo...@free.fr added the comment: The MALLOC_MMAP_THRESHOLD improvement is less visible here: Are you running on 64-bit ? If yes, it could be that you're exhausting M_MMAP_MAX (malloc falls back to brk when there are too many mmap mappings). You could try with MALLOC_MMAP_THRESHOLD_=1024 MALLOC_MMAP_MAX_=16777216 ../opt/python issue11849_test.py By the way, never do that in real life, it's a CPU and memory hog ;-) I think the root cause is that glibc's malloc coalescing of free chunks is called far less often than in the original ptmalloc version, but I still have to dig some more. By the way, I noticed that dictionnaries are never allocated through pymalloc, since a new dictionnary takes more than 256B... On 64-bit builds indeed. pymalloc could be improved to handle allocations up to 512B. Want to try and write a patch? Sure.

Sijin Joseph sijinjos...@gmail.com added the comment:
Looking at object.h the buffer interface is defined as
/* buffer interface */
typedef struct bufferinfo {
void *buf;
PyObject *obj;/* owned reference */
Py_ssize_t len;
Py_ssize_t itemsize; /* This is Py_ssize_t so it can be
pointed to by strides in simple case.*/
int readonly;
int ndim;
char *format;
Py_ssize_t *shape;

mono-dimensional buffers. */

typedef int (*getbufferproc)(PyObject *, Py_buffer *, int);
typedef void (*releasebufferproc)(PyObject *, Py_buffer *);
typedef struct {
getbufferproc bf_getbuffer;
releasebufferproc bf_releasebuffer;
} PyBufferProcs;
The code that's throwing that error looks like
if (pb == NULL || pb-bf_getbuffer == NULL) {
PyErr_SetString(PyExc_TypeError,
expected an object with the buffer interface);
I would argue that the error message gives appropriate information because it
is expecting the object to have a bf_getbuffer member.
Maybe the friendly error message is best handled at a higher level?

[issue11922] Add General Index to Windows .chm help file Contents
New submission from Terry J. Reedy tjre...@udel.edu: The Windows distribution comes with the docs in a very nice Windows help file .chm form. When displayed, they is a left side bar with a Contents tab. The top entry is 'Python vx.y documentation' followed by 'Python Module Index' and 'What's New in Python' and so on down to 'History and Licence'. Everything on the Python vx.y documentation' page is listed in the Contents EXCEPT the General Index. Consequently, if one only uses the contents lists, one might not even know it exists. In any case, it is harder to get to than anything else. I presume the omission is unintentional. In any case, I would like to see it fixed, with 'General Index' added right after the module index entry. I presume this should be easy for someone who knows how the contents list is generated. -- assignee: docs@python components: Documentation, Windows keywords: easy messages: 134398 nosy: docs@python, terry.reedy priority: normal severity: normal stage: needs patch status: open title: Add General Index to Windows .chm help file Contents versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11922 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11846] Remove non-guaranteed implementation details from docs.
Terry J. Reedy tjre...@udel.edu added the comment: The range of interned ints was once much smaller, but it was expanded upwards to 256 so that the bytes extracted from bytes and bytearray objects, as when indexing or iterating, would *all* be pre-allocated objects. I should presume that their indexers and iterators are cognizant of this and take advantage of this to bypass int() creation and directly index into the the array of preallocated ints without a range check. As for space and some time saving, just on startup, a nearly fresh IDLE shell shows sum((sys.getrefcount(i) for i in range(-5, 257))) 4432 There are hundreds of references for each of 0 and 1. -- nosy: +terry.reedy ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11846 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11920] ctypes: Strange bitfield structure sizing issue
Amaury Forgeot d'Arc amaur...@gmail.com added the comment: The output is: 3 2 on windows. It is 2 2 on the linux 64bit I tried. This is consistent with what the usual compilers do on these platforms: MSVC on windows, and gcc on linux. The specification of the C language specifies that If an adjacent bitfield will not fit into the remainder of the unit, the implementation defines whether bitfields are allowed to span units or whether another unit is allocated for the second bitfield Are you using gcc on windows? In this case I suggest to always use the largest type to declare the bitfields. -- nosy: +amaury.forgeotdarc Added file: http://bugs.python.org/file21776/bitfields.c ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11920 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1943] improved allocation of PyUnicode objects
Amaury Forgeot d'Arc amaur...@gmail.com added the comment:
I just found that the extension zope.i18nmessageid:
http://pypi.python.org/pypi/zope.i18nmessageid subclasses unicode at the C
level:
http://svn.zope.org/zope.i18nmessageid/trunk/src/zope/i18nmessageid/_zope_i18nmessageid_message.c?rev=120914view=markup
Notably, the Message structure is defined this way:
typedef struct {
PyUnicodeObject base;
PyObject *domain;
PyObject *default_;
PyObject *mapping;
} Message;
How would such an extension type behave after the patch? Is there a workaround
we can propose?

[issue11920] ctypes: Strange bitfield structure sizing issue
Santoso Wijaya santoso.wij...@gmail.com added the comment:
What compilers were used to build your Python distro and the native structure?
I found out in _ctypes/cfield.c (lns. 76-95):
if (bitsize /* this is a bitfield request */
*pfield_size /* we have a bitfield open */
#ifdef MS_WIN32
/* MSVC, GCC with -mms-bitfields */
dict-size * 8 == *pfield_size
#else
/* GCC */
dict-size * 8 = *pfield_size
#endif
(*pbitofs + bitsize) = *pfield_size) {
/* continue bit field */
fieldtype = CONT_BITFIELD;
#ifndef MS_WIN32
} else if (bitsize /* this is a bitfield request */
*pfield_size /* we have a bitfield open */
dict-size * 8 = *pfield_size
(*pbitofs + bitsize) = dict-size * 8) {
/* expand bit field */
fieldtype = EXPAND_BITFIELD;
#endif
So the allocation of the extra byte for the structure seems to depend on
Python's compiler. To make sure, I compiled a native structure using MSVC:
#pragma pack(1)
typedef struct _struct1
{
UINT8 first : 1;
UINT8 second : 1;
UINT8 third : 1;
UINT8 fourth : 1;
UINT8 fifth : 1;
UINT16 pad: 11;
} struct1;
And I got the same value (sizeof == 3).

Not that it counts for much :) Me too. We still have a couple hundred RHEL4/5 boxes at work, and I guess we're not alone in this case. It's a really specific case, but I think it would be nice to fix it, especially since it also makes the code more understandable and less error-prone.

[issue10914] Python sub-interpreter test
STINNER Victor victor.stin...@haypocalc.com added the comment: Modules/_testembed fails with ISO-8859-15 locale encoding because of a bootstrap issue. The problem is that the filesystem encoding codec is implemented in Python: Python requires the codec to loads modules, but it has to load a module to load the codec. I already solved this issue in Python using C functions instead of the Python codec until Python is able to load modules (able to load the Python codec). The problem is the test on the python initialization: PyUnicode_EncodeFSDefault / PyUnicode_DecodeFSDefaultAndSize check the global Py_FileSystemDefaultEncoding variable (use C functions if it is NULL). We should use C functions if Py_FileSystemDefaultEncoding is NULL *or* if interp-codecs_initialized is zero. I think that Python used interp-codecs_initialized flag. I removed the test on interp-codecs_initialized because I thought that it was useless. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10914 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10517] test_concurrent_futures crashes with --with-pydebug on RHEL5 with Fatal Python error: Invalid thread state for this thread
Antoine Pitrou pit...@free.fr added the comment: I think that if we were to call PyThread_set_key_value twice on the same key it's either an error, or we want the last version to be stored, not the old one. Not necessarily. You can have several interpreters (and therefore several thread states) in a single thread, using Py_NewInterpreter(). It's used by mod_wsgi and probably other software. If you overwrite the old value with the new one, it may break such software.

[issue10914] Python sub-interpreter test
STINNER Victor victor.stin...@haypocalc.com added the comment: I think that Python used interp-codecs_initialized flag Yes in PyUnicode_AsEncodedString(), in Python 3.0 and 3.1. Python 3.2 has also the test, but PyUnicode_AsEncodedString() is no more used to encode filenames. I removed the test in Python 3.3. Extract of Python 3.1: /* During bootstrap, we may need to find the encodings package, to load the file system encoding, and require the file system encoding in order to load the encodings package. Break out of this dependency by assuming that the path to the encodings module is ASCII-only.

The problem is a little bit more complex. interp-codecs_initialized is set to 1 by _PyCodecRegistry_Init(), but the filesystem codec is not loaded yet. We need another variable: interp-fscodec_initialized. fscodec_subinterpreter.patch fixes this issue. Note: the patch replaces also PyErr_Print() by PyErr_PrintEx(0) to avoid a crash on error, if PyErr_PrintEx(0) is called before the sys module is initialized. For example, if PyModule_GetDict(_PyImport_FindBuiltin(builtins)) is NULL. Anyway, it's useless to set sys attributes on error, because sys is destroyed just after printing the error. -- Added file: http://bugs.python.org/file21778/fscodec_subinterpreter.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10914 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
