[issue4566] 2.6.1 breaks many applications that embed Python on Windows
Mark Hammond mhamm...@users.sourceforge.net added the comment: I've hacked together something that fixes the problem. I'm working on making it a real patch, but the basis is: * In DllMain (dl_nt.c), we call: case DLL_PROCESS_ATTACH: GetCurrentActCtx(PyWin_DLLhActivationContext); AddRefActCtx(PyWin_DLLhActivationContext); case DLL_PROCESS_DETACH: ReleaseActCtx(PyWin_DLLhActivationContext); (where PyWin_DLLhActivationContext is a module level HANDLE global) * The LoadLibraryEx (in dynload_win.c) changes to: ActivateActCtx(PyWin_DLLhActivationContext, cookie); /* XXX This call doesn't exist in Windows CE */ hDLL = LoadLibraryEx(... as currently ...); DeactivateActCtx(0, cookie); This makes the import socket test case work for me. I'm not sure what the impact will be should the .pyd file reference other assemblies. Also, the calls above all need to move to function pointer calls as the functions only exist on Vista and later (hence the slight delay in making a real patch) ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4566 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4804] Python on Windows disables all C runtime library assertions
Kristján Valur Jónsson krist...@ccpgames.com added the comment: Yes, this is the biggest reason why this is required. This, and and os.closerange(). I have browsed the CRT source and I find no way to determine if a fd is actually valid, before calling any of the functions that check for it. Reintroducing the assertion will prevent a debug build python from passing the testsuite. Much as I think this is useful (turning on the crt tests helped me find a couple of python bugs recently) it unfortunately needs to be off because of os.close(). All other troublesome cases (strftime(), open()) have workarounds.

[issue4804] Python on Windows disables all C runtime library assertions
Kristján Valur Jónsson krist...@ccpgames.com added the comment: Btw, It occurred to me that a more gentle way to do this is to disable the functionality only around close(). This is far less intrusive, for example, in an embedded environment. I must confess that I had completely forgototten about the disabling of the assertion and only stumbled on this recently when I was trying to find out why none of my _ASSERTS in eve worked! Making wholesale CRT settings certainly should be avoided. So, as I said, we could very well avoid this by just wrapping a few instances of close() with a CrtSetErrorHandler calls and friends. With the caveat that these are not threadsafe, that is, it is a process global setting for the CRT. But toggling it during a limited scope surely is less intrusive than modifying it for the entire process permanently.

Mark Hammond mhamm...@users.sourceforge.net added the comment: It would be interesting to know which tests actually fail. If the tests are explicitly checking a bad fd, then IMO it makes more sense for that test to simply be avoided in debug builds and nothing of value would be left untested.

[issue4796] Decimal to receive from_float method
Mark Dickinson dicki...@gmail.com added the comment:
Accordingly, I recommend Decimal.from_float(f) with no qualifiers or
optional arguments.
I agree with this. Since lossless conversion is feasible, this seems
the obvious way to go.
It's lucky that the exponent range for (binary) floats is relatively
small, though: for IEEE 754 floats the worst case conversions (e.g.,
(2**53-1)/2**1074) produce Decimals with something like 767 significant
digits, which is still plenty small enough not to cause difficulties.
The recipe in the docs is not industrial strength: it doesn't handle
infinities, nans and negative zero. I think there's a place for a
from_float method that handles these special cases correctly---or at
least as correctly as reasonable: +-infinity should convert to +-
infinity, nans to (quiet) nans. I don't think it's worth worrying about
preserving the sign or payload of a binary nan: just convert all float
nans to Decimal('NaN').I do however think it's worth trying to
preserve the sign of negative zero. Note: I'm not suggesting changing
the *documentation* at all---the recipe there is fine as it is, IMO, but
I think an official version should include these corner cases.

[issue4796] Decimal to receive from_float method
Mark Dickinson dicki...@gmail.com added the comment:
One also has to worry about the exponent of the converted result: e.g.,
should Decimal.from_float(10.0) produce Decimal('1E1') or Decimal('10')?
The latter looks nicer, to me.
IEEE 754 isn't much help here: as far as I can tell it says nothing about
binary - decimal conversions.
I see two reasonable strategies: (1) always use the largest exponent
possible (so we'd get Decimal('1E1') above), or (2) when the quantity
converted is an exact integer, use an exponent of zero; otherwise fall
back to (1).
Option (2) is pretty much what the recipe in the docs does already, I
think: it computes a quotient of two Decimals, each having exponent zero,
so the preferred exponent of the result is also zero.

[issue4806] Function calls taking a generator as star argument can mask TypeErrors in the generator
New submission from Hagen Fürstenau hfuerste...@gmx.net: If we call some function f with a generator as star argument and this generator raises a TypeError, we get the following exception: def f(x): pass ... def broken(): raise TypeError ... f(*(broken() for x in (0,))) Traceback (most recent call last): File stdin, line 1, in module TypeError: f() argument after * must be a sequence, not generator This is a misleading error message, as it's usually no problem to use a generator as a star argument. Even just replacing the TypeError by some other exception leads to the expected result, i.e. the exception gets correctly propagated. The problem seems to be around line 3710 of Python/ceval.c where the generator is converted to a tuple. If this conversion raises a TypeError, then the error message is replaced, which will mask any TypeError raised by the generator. I'm not sure how to solve this. We probably can't distinguish a good TypeError from a bad TypeError at this point, so we might have to make a special case for the conversion of generators. -- components: Interpreter Core messages: 78788 nosy: hagen severity: normal status: open title: Function calls taking a generator as star argument can mask TypeErrors in the generator type: behavior versions: Python 2.6, Python 3.0 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4806 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Also, why not just extend the Decimal() constructor to accept a float

suggest a separate method modeled on Context.create_decimal().

[issue4796] Decimal to receive from_float method
Mark Dickinson dicki...@gmail.com added the comment:
Just for the avoidance of all doubt, do you mean the largest exponent
with the number normalised to one digit to the right of the decimal
place?
No. I'm using 'exponent' in the sense described in the standard. See:
http://speleotrove.com/decimal/dbover.html
Equivalently, it's the value of the _exp attribute for a Decimal
instance. (For the purposes of disambiguation, the alternative exponent
that you describe above is often referred to as the 'adjusted exponent'
in the documentation and code.)
Briefly, every finite Decimal can be thought of as a triple (sign,
coefficient, exponent), representing the value (-1)**sign * coefficient
* 10**exponent, with the coefficient an integer. It's this exponent
that should be maximized.
Because 1e1 = 0.1e2 = 0.01e3 = ... and there is no largest
exponent possible
All these have exponent 1:
Decimal('1e1')._exp
1
Decimal('0.1e2')._exp
1
Decimal('0.01e3')._exp
1
IOW, leading zeros have no significance; only trailing zeros do.
Also, why not just extend the Decimal() constructor to accept a float
as the argument? Why have a separate from_float() method at all?
This was discussed extensively when the decimal module was being
proposed; see the Decimal PEP for arguments against this.

[issue4791] retrlines('LIST') and dir hang at end of listing in ftplib (python3.0)
STINNER Victor victor.stin...@haypocalc.com added the comment:
Can you paste the full output with debuglevel=3?
if not line: should be equivalent to if len(line) == 0: and to if
line == '':.
ftp.dir() is equivalent to ftp.retrlines('LIST').
By default, the socket created to get the result of LIST has no
timeout (is blocking). So fp.readline() only returns an empty string
when the socket is closed (by the server).
fp is a io.BufferedReader(SocketIO(socket, r),
io.DEFAULT_BUFFER_SIZE).

[issue4751] Patch for better thread support in hashlib
STINNER Victor victor.stin...@haypocalc.com added the comment: Releasing the GIL is somewhat expensive and should be avoided if possible. Another possible solution is to create a lockless object by default, and create a lock if the data size is bigger than N (eg. 8 KB). When the lock is created, update will always use the lock (and so the GIL). In general, you have two classes of hashlib usages: - hash a big files by chunk of k KB (eg. 256 KB) - hash a very small string (eg. 8 bytes) When you have a small string, you don't need to release the GIL nor to use locks. Whereas for a file, you can always release the GIL (and so you need a lock to protect the context). ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4751 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Since the patch heavily relies on the compiler doing the right thing (which esp.

This is safer than enabling the support unconditionally for GCC and the SUN Pro C compiler, since it is rather likely that some GCC versions have bugs which could render Python unusable if compiled with the dispatching support enabled. A configure option also has the additional benefit that you can enable the support for compilers which support the syntax, but are not included in the hard-coded list of compilers included in the patch. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4753 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2121] complex constructor doesn't accept string with nan and inf
Mark Dickinson dicki...@gmail.com added the comment:
[Raymond]
I would
not like to see that extended to cmath or complex() unless compelling
real-world use cases arise.
Hmm. Have you looked at the cmath module recently? You may be in for a
nasty surprise...
Mark, does Inf have a standard interpretation for complex numbers? Do
all infinities meet or do they radiate, each with their own phase
angle?
Shrug. Mathematically, by far the most common and useful model is the
complex plane plus a single extra point at infinity. But when complexes
are implemented as pairs of floats things look a little strange. Kahan,
in his 'branch cuts' paper identifies 9 'different' complex infinities
in this model, and C99 Annex G specifies exactly how functions should
behave for various different infinities.
It's never really been clear to me how useful it is to be able to
distinguish these infinities. But the cmath module *does* make an
effort to return the 'correct' (according to C99 Annex G) values for
inputs with a special real or imaginary component. On balance, I'd
support making complex('nan + nan*j') do the right thing.
(Though I can't help feeling that the repr of complex(nan, nan)
should have been 'nan + nan*1j' rather than the current 'nan + nan*j'.)
Also, do you want to stick with the 754 interpretation of NaNs as the
result of invalid operations
I've never much liked the use of NaN to represent missing values, and
I don't think Python should embrace that usage.

[issue4794] garbage collector blocks and takes worst-case linear time wrt number of objects
Martin v. Löwis mar...@v.loewis.de added the comment: Hard real-time applications written in Python should not rely on the cyclic garbage collector. They should call gc.disable at startup, and completely rely on reference counting for releasing memory. Doing so might require rewrites to the application, explicitly breaking cycles so that reference counting can release them. Even with cyclic gc disabled, applications worried about meeting hard deadlines need to look even more into memory allocation and deallocation; e.g. releasing a single object may cause a chained release of many objects, which can affect worst case execution times.

[issue4753] Faster opcode dispatch on gcc
Marc-Andre Lemburg m...@egenix.com added the comment: On 2009-01-02 17:10, Antoine Pitrou wrote: Antoine Pitrou pit...@free.fr added the comment: This is safer than enabling the support unconditionally for GCC and the SUN Pro C compiler, since it is rather likely that some GCC versions have bugs which could render Python unusable if compiled with the dispatching support enabled. What do you mean, unusable? Well, not working. GCC versions often have optimizer bugs (esp. the 3.x series and early 4.x versions) and I wouldn't bet on them always getting the dispatch optimizations right. Trying to compile Python with an unconditionally enabled dispatch patch on such a system would render Python unusable. 10% slower? Well, Python 3.x is already unusable (compared to 2.x) by that metric... Until now, only Skip has reported a slowdown on his PPC machine, while x86 systems have all seen a positive (if tiny, sometimes) improvement. I fear that with a configure option, disabled by default, the code will get very poor testing and perhaps get broken in some subtle way without anyone noticing. Like Skip said: the buildbots could take care of identifying such problems. People using the option would certainly report problems as well and I'm sure that Linux distributions would compile Python with the switch after verifying that their GCC version works correctly. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4753 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4796] Decimal to receive from_float method
Steven D'Aprano st...@pearwood.info added the comment:
Mark wrote:
Also, why not just extend the Decimal() constructor to accept
a float as the argument? Why have a separate from_float()
method at all?
This was discussed extensively when the decimal module was
being proposed; see the Decimal PEP for arguments against this.
I'm very aware of that. The Decimal PEP says the consensus was for
from_float() to take a second argument specifying the precision.
Decimal(1.1) = Decimal(1.1) was rejected for the reasons given in
the PEP by Paul Moore, and Decimal(1.1) =
Decimal('110008881784197001252...e-51') was (presumably)
rejected because it would confuse newbies. Hence the decision to (1)
make an alternative constructor and (2) have it take a second
argument.
It looks like you and Raymond have rejected #2 but are keeping #1, and
I'm curious why. That's genuine curiosity, and a real question, not a
thinly-veiled scowl of disapproval disguised as a question :)
Anyway, I'm happy enough so long as Raymond's suggested
Context.create_decimal() exists, that's the actual functionality I'm
after, so maybe I should let you guys get on with it. Thanks.

[issue4796] Decimal to receive from_float method
Mark Dickinson dicki...@gmail.com added the comment:
It looks like you and Raymond have rejected #2 but are keeping #1
I'm not against #2, but I'm not particularly for it either. In any case,
once you've converted your float to Decimal it's trivial to round it to
whatever precision you feel like, so #2 seems unnecessary to me. -0.0.
I am -1.100088817841970012523233890533447265625 on any
implementation of from_float (with or without keywords, defaults, etc.)
for which Decimal.from_float(1.1) gives Decimal('1.1').
