Pragma-style declaration syntax
by M.-A. Lemburg Sept. 2, 2000

Sept. 2, 2000

I've been tossing some ideas around w/r to adding pragma style declarations to Python and would like to hear what you think about these: 1. Embed pragma declarations in comments: #pragma: name = value Problem: comments are removed by the tokenizer, yet the compiler will have to make use of them, so some logic would be needed to carry them along. 2. Reusing a Python keyword to build a new form of statement: def name = value Problem: not sure whether the compiler and grammar … [View More]

lookdict
by Vladimir.Marangozov＠inrialpes.fr Sept. 1, 2000

Sept. 1, 2000

I'd like to request some clarifications on the recently checked dict patch. How it is supposed to work and why is this solution okay? What's the exact purpose of the 2nd string specialization patch? Besides that, I must say that now the interpreter is noticeably slower and MAL and I were warning you kindly about this code, which was fine tuned over the years. It is very sensible and was optimized to death. The patch that did make it was labeled "not ready" and I would have appreciated another … [View More]

threadmodule.c comment error? (from comp.lang.python)
by Fredrik Lundh Sept. 1, 2000

Sept. 1, 2000

as noted by curtis jensen over at comp.lang.python: the parse tuple string doesn't quite match the error message given if the 2nd argument isn't a tuple. on the other hand, the args argument is initialized to NULL... thread_PyThread_start_new_thread(PyObject *self, PyObject *fargs) { PyObject *func, *args = NULL, *keyw = NULL; struct bootstate *boot; if (!PyArg_ParseTuple(fargs, "OO|O:start_new_thread", &func, &args, &keyw)) return NULL; if (!PyCallable_Check(func)) { … [View More]

Prerelease Python fun on Windows!
by Tim Peters Sept. 1, 2000

Sept. 1, 2000

A prerelease of the Python2.0b1 Windows installer is now available via anonymous FTP, from python.beopen.com file /pub/windows/beopen-python2b1p1-20000901.exe 5,766,988 bytes Be sure to set FTP Binary mode before you get it. This is not *the* release. Indeed, the docs are still from some old pre-beta version of Python 1.6 (sorry, Fred, but I'm really sleepy!). What I'm trying to test here is the installer, and the basic integrity of the installation. A lot has changed, and … [View More]

Cookie.py security
by A.M. Kuchling Sept. 1, 2000

Sept. 1, 2000

[CC'ed to python-dev and Tim O'Malley] The Cookie module recently added to 2.0 provides 3 classes of Cookie: SimpleCookie, which treats cookie values as simple strings, SerialCookie, which treats cookie values as pickles and unpickles them, and SmartCookie which figures out if the value is a pickle or not. Unpickling untrusted data is unsafe. (Correct?) Therefore, SerialCookie and SmartCookie really shouldn't be used, and Moshe's docs for the module say so. Question: should SerialCookie … [View More]

cPickle.c out-of-date w.r.t. version in Zope 2.2.1
by Skip Montanaro Sept. 1, 2000

Sept. 1, 2000

I'm trying to get Zope 2.2.1 to build to I can use gc to track down a memory leak. In working my way through some compilation errors I noticed that Zope's cPickle.c appears to be somewhat different than Python's version. (Haven't checked cStringIO.c yet, but I imagine there may be a couple differences there as well.) Should we try to sync them up before 2.0b1? Before 2.0final? Wait until 2.1? If so, should I post a patch to the SourceForge Patch Manager or send diffs to Jim (or both)? Skip

DEBUG_SAVEALL feature for gc not in 2.0b1?
by Martin von Loewis Sept. 1, 2000

Sept. 1, 2000

> Does this look okay? Should I try to get it done for 2.0? I don't see the need for improvement. I consider it a fairly low-level API, so having bit masks is fine: users dealing with this settings should know what a bit mask is. As for the naming of the specific flags: So far, all of them are for debugging, as would be the proposed DEBUG_SAVEALL. You also have set/get_threshold, which clearly controls a different kind of setting. Unless you come up with ten or so additional settings … [View More]

linuxaudiodev test does nothing
by Jeremy Hylton Sept. 1, 2000

Sept. 1, 2000

Is the test for linuxaudiodev supposed to play the Spanish Inquistion .au file? I just realized that the test does absolutely nothing on my machine. (I guess I need to get my ears to raise an exception if they don't hear anything.) I can play the .au file and I use a variety of other audio tools regularly. Is Peter still maintaining it or can someone else offer some assistance? Jeremy
