[issue12026] Support more of MSI api by exposing handles
Mark Mc Mahon mtnbikingm...@gmail.com added the comment: You can pass it to any function in the MSI SDK through ctypes. e.g. def ReadStream(record, field): buf = (ctypes.c_char * 2048)() orig_size = ctypes.sizeof(buf) status = 0 res = [] while status == 0: size = ctypes.c_long(ctypes.sizeof(buf)) status = msidll.MsiRecordReadStream( record.hanlde, field, ctypes.byref(buf), ctypes.byref(size)) res.append(buf.raw) if size.value != orig_size: break data = .join(res) return data or any of the other functions not currently implemented in _msi.c Some of the other important ones (to me at least) are: - MsiDatabaseGetPrimaryKeys - MsiDatabaseExport - MsiDatabaseImport If the whole MSI SDK is wrapped - then exposing the handles would have no use :). The alternative I have so far is to re-write _msi.c using ctypes (already done), but I thought it would be better if not all of _msi.c had to be re-implemented. One alternative patch is to include those extra functions in _msi.c (though I am not sure I have the C skills to achieve that easily - and it may still miss functionality, and it may have even less chance of being accepted) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12026 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12029] ABC registration of Exceptions
New submission from andrew cooke and...@acooke.org:
Hi,
In general, registering a class with an ABC is equivalent to making it a
subclass (isinstance and issubclass are patched through ABCMeta). However,
this does not work for exceptions (see example below, where exception is not
caught).
This doesn't seem terribly surprising to me - I imagine that checking would
slow down exception handling - but I couldn't find any documentation (and
posting on c.l.p didn't turn up anything either).
So I thought I would raise it here - perhaps there is a possible fix (my
obscure use case is that I have a backtracking search; backtracking occurs when
a certain exception is encountered; making that exception an ABC and allowing
existing exceptions to be registered with it allows the search to work with
existing code without a wrapper that catches and translates exceptions that
should trigger a backtrack). Or perhaps the docs could be extended. Or
perhaps I've misunderstood something...
Cheers,
Andrew

[issue10713] re module doesn't describe string boundaries for \b
Ralph Corderoy ralph-pythonb...@inputplus.co.uk added the comment:
Examining the source of Ubuntu's python2.6 2.6.6-5ubuntu1 package
suggests beyond the limits of the string is considered \W, like Perl.
Modules/_sre.c:
336 LOCAL(int)
337 SRE_AT(SRE_STATE* state, SRE_CHAR* ptr, SRE_CODE at)
338 {
339 /* check if pointer is at given position */
340
341 Py_ssize_t thisp, thatp;
...
365 case SRE_AT_BOUNDARY:
366 if (state-beginning == state-end)
367 return 0;
368 thatp = ((void*) ptr state-beginning) ?
369 SRE_IS_WORD((int) ptr[-1]) : 0;
370 thisp = ((void*) ptr state-end) ?
371 SRE_IS_WORD((int) ptr[0]) : 0;
372 return thisp != thatp;
SRE_IS_WORD() returns 16 for the 63 \w characters, 0 otherwise.
This is born out by tests.
Note, 366 above confirms it's never true for an empty string. The
documentation states that \B is just the opposite of \b yet
re.match(r'\b', '') returns None and so does \B so \B isn't the opposite
of \b in all cases.

[issue9971] Optimize BufferedReader.readinto
Antoine Pitrou pit...@free.fr added the comment: The trade-off of accommodating a small buffer size (by buffering behind the scenes anyways) would likely slow the more common cases which use a decent buffer size. I am wondering if an effort to accommodate both uses would be appropriate. Possibly by not double-buffering if readinto(b): len(b) buffer_size/2 (arbitrary but seems feasible), and copying directly as the patch does now. Otherwise, fill the buffer up for subsequent reads and copy len(b) to user buffer. There is probably a good equilibrium for when it makes more/less sense to bypass the internal buffer. Yes, it sounds reasonable. I think the best thing to do is to experiment and run some measurements. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9971 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12034] check_GetFinalPathNameByHandle() suboptimal
New submission from Antoine Pitrou pit...@free.fr:
The code for check_GetFinalPathNameByHandle() goes like this:

{
[...]
has_GetFinalPathNameByHandle = Py_GetFinalPathNameByHandleA
Py_GetFinalPathNameByHandleW;
}

}
It means that if the computed value is 0 (system doesn't have
GetFinalPathNameByHandle*), the value will be re-computed each time the
function is called. has_GetFinalPathNameByHandle should probably be tri-state
instead (0, 1, unknown).

[issue11983] Inconsistent hash and comparison for code objects
Eugene Toder elto...@gmail.com added the comment: It appears that * co_name was added to hash and cmp in this check-in by Guido: http://hg.python.org/cpython-fullhistory/diff/525b2358721e/Python/compile.c I think the reason was to preserve function name when defining multiple functions with the same code in one function or module. (By default function gets it's name from code, but only one code object will be preserved, since all constants in a function are stored in a dict during compilation). * co_firstlineno was added to cmp (but not hash) in this check-in by Brett: http://hg.python.org/cpython-fullhistory/rev/8127a55a57cb In an attempt to fix this bug: http://www.mail-archive.com/python-bugs-list@python.org/msg02440.html It doesn't actually fix the bug and makes hash inconsistent with cmp. I'm not convinced that the bug is valid -- why would you care if identical lambdas share or not share the code? Both changes seem come from a tension between code object's original intention to compare functionally equivalent codes equal and side-effects of constants de-duplication in a function (loss of function name, broken breakpoints and line numbers in a debugger). I can think of 2 ways to address this. Change hash/cmp back to ignore co_name and co_firstlineno and then: 1) Never dedup codes, or only dedup codes with the same co_firstlineno (can compare co_name too, but I can't think of a way to create 2 named funcs on the same line). This is pretty much what the current code does. 2) Separate debug information (co_filename, co_name, co_firstlineno, co_lnotab) from code object into a separate object. Construct a function from both objects. Allow de-duplication of both. This will always preserve all information in a function, but allows to share code object between identical functions. This is a much more intrusive change, though, e.g. frame will need a reference to debug information. -- nosy: +Jeremy.Hylton, brett.cannon, ncoghlan ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11983 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6721] Locks in python standard library should be sanitized on fork
Antoine Pitrou pit...@free.fr added the comment: Thanks for the explanations. This sounds like an interesting path. Each thread implementation (thread_pthread.h, thread_nt.h) would provide a new PyThread_reinit_lock function that would do the right thing (pthread_mutex_destroy/init, sem_destroy/init, etc). Modules/threadmodule.c would provide a new PyThread_ReInitLocks that would walk through the linked list and call PyThread_reinit_lock for each lock. Actually, I think the issue is POSIX-specific: Windows has no fork(), and we don't care about other platforms anymore (they are, are being, or will be soon deprecated). It means only the POSIX implementation needs to register its locks in a linked list. But this wouldn't allow a lock's state to be inherited across fork for the main thread (but like I said, I don't think that this makes much sense anyway, and to my knowledge no implementation makes such a guarantee - and definitely not POSIX). Well, the big difference between Python locks and POSIX mutexes is that Python locks can be released from another thread. They're a kind of trivial semaphore really, and this makes them usable for other purpose than mutual exclusion (you can e.g. use a lock as a simple event by blocking on a second acquire() until another thread calls release()). But even though we might not be fixing arbitrary Python code automatically, fixing the interpreter's internal locks (especially the IO locks) would be great already. (we could also imagine that the creator of the lock decides whether it should get reinitialized after fork) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6721 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9205] Parent process hanging in multiprocessing if children terminate unexpectedly
Antoine Pitrou pit...@free.fr added the comment: Ok, here's a patch for the new approach. CancelIoEx is loaded dynamically and, if unavailable, CancelIo is used instead. I take care to cancel or complete the I/O in the same method call where it is initiated, meaning there's no thread-specificity issues. (of course, all this is a lot of code just to have the desired WaitForMultipleObjects() semantics on a named pipe.

Based on the above I think you are right about using the internal buffer
regardless (revision attached). You pay a price with larger buffer sizes but on
balance it seems to be a much better general purpose solution. The java-like
solution is decent as well, it is only slightly slower for small reads and
optimal
