What's New in 2.6 link wasn't what I expected
by skip＠pobox.com Sept. 19, 2008

Sept. 19, 2008

>From this page: http://www.python.org/download/releases/2.6/ I clicked the link labelled "What's new in Python 2.6rc2". This didn't take me to the What's New page. Instead it took me to: http://www.python.org/download/releases/2.6/NEWS.txt Seems a bit mislabelled if nothing else. Poking around I see that the 2.5 What's New document is at: http://docs.python.org/dev/whatsnew/whatsnew25.html but http://docs.python.org/dev/whatsnew/whatsnew26.html doesn't exist. Am I missing something? Skip

ssl module, non-blocking sockets and asyncore integration
by Giampaolo Rodola' Sept. 18, 2008

Sept. 18, 2008

Hi, I try to revamp a discussion I raised some time ago and which seems to be not solved yet. I'm interested in using the ssl module with asyncore but since there's no real documentation about how using ssl module with non-blocking sockets I've not been able to write something useful with it. I took a look at Test/test_ssl.py which seems to include a test consisting in an asyncore-based secure server but I noticed something strange: def __init__(self, conn, certfile): asyncore.dispatcher_with_send.__init__(self, conn) self.socket = ssl.wrap_socket(conn, server_side=True, certfile=certfile, do_handshake_on_connect=True) I'm not sure about the real meaning of the do_handshake_on_connect parameter but if it does what I think it should block the application as long as the handshake isn't finished, which is not acceptable in an asynchronous environment. Am I misunderstanding something? Does the ssl module can actually be used with non-blocking sockets? If so which is the proper/recommended way to do that? Thanks in advance --- Giampaolo http://code.google.com/p/pyftpdlib/

FreeBSD 7 amd64 and large memory tests
by Andrew MacIntyre Sept. 18, 2008

Sept. 18, 2008

I noticed issue 3862 (http://bugs.python.org/issue3862), which appears to be exposed only on FreeBSD 7.0 amd64 (perhaps 64 bit FreeBSD 7, but amd64 is the only 64bit hardware I can check). As far as I can make out from a couple of quick checks, this appears to be happening because the process is killed before the malloc() that exhausts the available swap space is allowed to report an out of memory condition. FreeBSD's default process virtual memory limit (ulimit -v) on both i386 and amd64 is "unlimited" for 6.3 and 7.0. Setting ulimit -v to a finite value on 7.0 amd64 seems to give rise to "normal" malloc() behaviour so that test_array passes. FreeBSD 7 uses a different malloc() implementation than FreeBSD 6 and earlier, and the new implementation uses mmap() in preference to sbrk(). So I suspect that behaviour was "normal" on FreeBSD 6 amd64 (can't test at the moment as I don't have that installed anywhere). Behaviour appears "normal" on FreeBSD 7 i386 as well. I haven't yet tried posting a query to a FreeBSD list, as it could simply be a bug on amd64, but I was wondering whether there was anything (other than deactivating tests and documenting use of ulimit -v on this platform) that could be done to work around this behaviour.

switching on -3 from within a program?
by Anthon van der Neut Sept. 17, 2008

Sept. 17, 2008

With a minor modification to the Makefile I was able to get mod_wsgi v2.3 to work with python2.6rc1. I promptly got a warning in my apache log files on the depcrecated use of 'sha' in the paste's cookie module, good! And easily fixed. After that I was looking for a way to switch on the -3 warnings from within my code to have extra warnings show up in my apache log file. After reading some documentation I tried from the python2.6 prompt: import sys sys.py3kwarning = True x = { 'abc': 1 }; x.has_key('abc') which does not give a warning (starting python2.6 with the -3 option of course does). Is there anyway to switch this on from within a program with a Python statement? If not, would I need to make a small C-extension module (to be imported as the first module) that sets Py_Py3WarningFlag or something else at the C level, or would that better be done by mod_wsgi's C code. Regards Anthon

RELEASED Python 2.6rc1
by Barry Warsaw Sept. 17, 2008

Sept. 17, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team and the Python community, I am happy to announce the first release candidate for Python 2.6. This is a release candidate, so while it is not suitable for production environments, we strongly encourage you to download the release and test it on your software. We expect only critical bugs to be fixed between now and the final 2.6 release, still scheduled for October 1st, 2008. There is one more release candidate planned for September 17th. You might notice that unlike earlier releases, we are /not/ releasing Python 3.0rc1 at this time. It was decided that 3.0 still needs time to resolve open issues and that we would not hold up the 2.6 release for this. We feel that Python 2.6 is nearly ready for its final release. If you find things broken or incorrect, please submit bug reports at http://bugs.python.org For more information and downloadable distributions, see the Python 2.6 website: http://www.python.org/download/releases/2.6/ (Note that the Windows installers will be uploaded shortly.)

Re: [Python-Dev] ',' precedence in documentation]
by Christopher Lee Sept. 16, 2008

Sept. 16, 2008

> ----- Forwarded message from Guido van Rossum <guido(a)python.org> ----- > > Note that in any case, the 'in' operator binds more tightly than the > comma: e.g. f(x in y, z) means f((x in y), z). Exactly the point I was trying to make. As far as the user's concerned, an expression list x,y can itself be part of an expression; x in y is also an expression. Such expressions can be combined to form larger expressions, so it follows logically that you need to know which has precedence when *both* occur in an expression, e.g. whether x in y,z evaluates as (x in y),z or x in (y,z) The page that Fredrik sent you to (http://docs.python.org/ref/exprlists.html ) doesn't address that question. I still think the precedence table (http://docs.python.org/ref/summary.html ) should show that "in" has higher precedence than comma in an expression. Can anyone show us "where it is written" in the Python docs that "in" has higher precedence than comma, *and* why there is a good reason that this information should NOT be included in the precedence table? -- Chris Adding comma to the precedence table would also disambiguate expressions like: x and y,z x,y or z not x,y

The above four tests run without any problems for me, but I'm just running them in a normal Kubuntu desktop shell. Cheers, Nick. P.S. I'm in the process of creating a --with-pydebug build to see if that makes any difference. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia --------------------------------------------------------------- http://www.boredomandlaziness.org

Weak Dictionary Iteration Behavior in Python 3
by Armin Ronacher Sept. 15, 2008

Sept. 15, 2008

Hi everybody, In Python 2.x when iterating over a weak key dictionary for example, the common idom for doing that was calling dictionary.keys() to ensure that a list of all objects is returned it was safe to iterate over as a weak reference could stop existing during dict iteration which of course raises a runtime error by the dict iterator. This was documented behavior and worked pretty well, with the small problem that suddenly all references in the dict wouldn't die until iteration is over because the list holds references to the object. This no longer works in Python 3 because .keys() on the weak key dictionary returns a generator over the key view of the internal dict which of course has the same problem as iterkeys in Python 2.x. The following code shows the problem:: from weakref import WeakKeyDictionary f1 = Foo() f2 = Foo() d = WeakKeyDictionary() d[f1] = 42 d[f2] = 23 i = iter(d.keys()) # or use d.keyrefs() here which has the same problem print(next(i)) del f2 print(next(i)) This example essentially dies with "RuntimeError: dictionary changed size during iteration" as soon as f2 is deleted. Iterating over weak key dictionaries might not be the most common task but I know some situations where this is necessary. Unfortunately I can't see a way to achieve that in Python 3. Regards, Armin

If not, I'll remove the traces from the docs, where they only serve to confuse where MacOS X actually belongs under "Unix", not "Mac". Georg -- Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out.

2.6 rc1 performance results
by A.M. Kuchling Sept. 14, 2008

Sept. 14, 2008

Three weeks ago, Antoine Pitrou posted the pybench results for 2.6 trunk: http://mail.python.org/pipermail/python-dev/2008-August/081951.html The big discovery in those results were TryExcept being 48% slower, but there was a patch in the bug tracker to improve things. I've re-run the tests to check the results. Disclaimer: these results are probably not directly comparable. Antoine was using a "32-bit Linux installation on an Athlon 3600+ X2"; I'm on a Macbook. Good news: TryExcept is now only 10% slower than 2.5, not 48%. Bad news: the big slowdowns are: CompareFloats: 117ms 98ms +19.2% 118ms 99ms +19.0% CompareIntegers: 110ms 104ms +5.6% 110ms 105ms +4.9% DictWithStringKeys: 118ms 105ms +12.8% 133ms 108ms +22.7% NestedForLoops: 125ms 116ms +7.7% 127ms 118ms +8.0% Recursion: 193ms 159ms +21.5% 197ms 163ms +20.8% SecondImport: 139ms 129ms +8.4% 143ms 130ms +9.9% SecondPackageImport: 150ms 139ms +8.6% 152ms 140ms +8.1% SecondSubmoduleImport: 211ms 191ms +10.5% 214ms 195ms +9.4% SimpleComplexArithmetic: 130ms 119ms +9.4% 131ms 120ms +9.2% Antoine, your Recursion results were actually about the same (+2.2%) from 2.5 to 2.6, so this big slowdown is novel. I wonder if these tests are simply slower on MacOS for some reason (compiler, CPU cache size, etc.). Does anyone see similar results? Any idea what might have made DictForStringKeys and Recursion slow down?

Re: [Python-Dev] Add python.exe to PATH environment variable
by Henning von Bargen Sept. 13, 2008

Sept. 13, 2008

One of the things I like about Python is that * it doesn't actually need an installation. * It is sufficient to set up PATH (and, if you like, PYTHONPATH) accordingly to start python. However, you need the DLLs somewhere in the Python directory, too. That way it is possible to install Python applications in a minimal-invasive fashion: Just copy one directory to the hard-disk (or a network drive) and create a shortcut to some start-app.cmd script For example, this is a great advantage if you need to install a Python application on a client's application server, since the client's IT departments in reponsibility for the server absolutely don't like it when programs modify PATH or install DLLs in the %WINDIR%\System32 directory - and they are right here!!! Think of what happens if a program modifies PATH: The modification does not affect running services, of course. But *after a reboot* (possibly a few months later), the old services will find another version of some program than before, and then someting is going to crash! I have seen too much trouble of this kind after the installation of a different Perl version or a another Oracle product. The reason is then quite hard to find: if the installation of another software was 3 months ago, will anyone remember? And will anyone even consider it could be the reason for the fault after the reboot? Well - I will, but most others probably won't. I don't want this kind of trouble too happen with Python! So, please try keeping the Python installation as minimal invasive as possible. Note: This could also be an option for the installation. Henning

Updated release schedule for 2.6 and 3.0
by Barry Warsaw Sept. 12, 2008

Sept. 12, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We had a lot of discussion recently about changing the release schedule and splitting Python 2.6 and 3.0. There was general consensus that this was a good idea, in order to hit our October 1 deadline for Python 2.6 final at least. There is only one open blocker for 2.6, issue 3657. Andrew, Fred, Tim and I (via IRC) will be getting together tonight to do some Python hacking, so we should resolve this issue and release 2.6rc1 tonight. We'll have an abbreviated 2.6rc1, and I will release 2.6rc2 next Wednesday the 17th as planned. The final planned release of 2.6 will be Wednesday October 1st. If 3.0 is looking better, I will release 3.0rc1 on Wednesday, otherwise we'll re-evaluate the release schedule for 3.0 as necessary. This means currently the schedule looks like this: Fri 12-Sep 2.6rc1 Wed 17-Sep 2.6rc2, 3.0rc1 Wed 01-Oct 2.6 final, 3.0rc2 Wed 15-Oct 3.0 final I've updated the Python Release Schedule gcal and will update the PEP momentarily. We'll close the tree later tonight (UTC-4). - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSMpmfHEjvBPtnXfVAQJUiQP/eTXStyp9M0+Ja7iAFfYcpzfM19j9ddBr ocMC+KTDSgci5/rmFw4KdMhqO9TBk2sXIdCd9GInnuMOKtndCKZ/PXaexnVvSVGb P3CpkkMs/vG1itQIc/EXq6CUhzwuxEv9h8Wo8+zcmL05Cc1IrE5d2OYiO0+KQ8ei lW+j/aNKMWY= =w2oI -----END PGP SIGNATURE-----

Python 3.0: can we make dbm's .keys() return an iterator?
by Gerhard Häring Sept. 12, 2008

Sept. 12, 2008

As far as I can see, the specification of the dbm interface is the module docstring in dbm/__init__.py, which reads: """ [...] It has the following interface (key and data are strings): d[key] = data # store data at key (may override data at # existing key) data = d[key] # retrieve data at key (raise KeyError if no # such key) del d[key] # delete data stored at key (raises KeyError # if no such key) flag = key in d # true if the key exists list = d.keys() # return a list of all existing keys (slow!) """ Now I thought that in Python 3.0, keys(), values() and friends should return iterators. Can we change at least the specification of the dbm module? We could then later in 3.1 change the implementations to return iterators instead of lists, too. I stumbled upon it cos I'm trying to help Skip with the SQLite-based implementation. -- Gerhard

HTTPS read-only SVN access is denied?
by techtonik Sept. 11, 2008

Sept. 11, 2008

SVN checkout over HTTPS protocol requires password. Is it intentional or just temporary server issue? I am behind a proxy that doesn't support PROPFIND requests and I can't test SVN+SSH, because 22 port is closed. Site docs keep silence about that HTTPS is used at all. Shouldn't authentication be asked only on write access in normal SVN setup? BTW, link to "current svn tree" is broken here - http://www.python.org/dev/patches/ -- --anatoly t.

new ssl module is incompatible with servers that drop privileges
by Forest Sept. 9, 2008

Sept. 9, 2008

I've been trying out the new ssl module, and I love it so far, except for the way it accepts private keys and certificates. It accept them only as paths to their location on the file system, which I believe means that a server can only support SSL if it has read permission to its private key file when client connections arrive. This is a problem for servers that bind to their socket and drop privileges as soon as they start up, a practice that is both common and recommended in the unix world. IMHO, this severely limits the new ssl module's utility, and discourages good security practices. Wouldn't it be better if we could specify keys and certificates as bytes or file-like objects? This would solve the security issue, give applications more flexibility in key management, and might also improve performance slightly (by avoiding file system operations at accept() time). Perhaps there's a workaround that I haven't noticed yet? A quick look at the source code didn't reveal any obvious way to specify keys other than as paths in the file system. http://bugs.python.org/issue3823

Not releasing rc1 tonight
by Barry Warsaw Sept. 9, 2008

Sept. 9, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm not going to release rc1 tonight. There are too many open release blockers that I don't want to defer, and I'd like the buildbots to churn through the bsddb removal on all platforms. Let me first thank Benjamin, Brett, Mark and Antoine for their help on IRC tonight. Here are the issues I'm not comfortable with deferring: 3640 test_cpickle crash on AMD64 Windows build 874900 threading module can deadlock after fork 3574 compile() cannot decode Latin-1 source encodings 3657 pickle can pickle the wrong function 3187 os.listdir can return byte strings 3660 reference leaks in 3.0 3594 PyTokenizer_FindEncoding() never succeeds 3629 Py30b3 won't compile a regex that compiles with 2.5.2 and 30b2 In addition, Mark reported in IRC that there are some regressions in the logging module. I appreciate any feedback or fixes you can provide on these issues. You might also want to look at the deferred blockers to see if there's anything that really should be blocking rc1. I'd like to try again on Friday and stick to rc2 on the 17th. - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSL9Y53EjvBPtnXfVAQJGXwP+JZUa5EWlQh7yzt7aFdEM3qgiFZnKqWhz TN4Cen0/eK8c4+t8a5WC+OLvc/P3PhMPhLSnE+g6IqQUO+pt+2LANgpAvCUrUahc Nk2pt3gCclcmWlzVvCBspVPZjFPkHsW0uVhgK6x1C/2Re90yjeBqPGgT4LGlmaR3 bz6A3iiUnk0= =Y5aN -----END PGP SIGNATURE-----

Re: [Python-Dev] [issue3769] Deprecate bsddb for removal in 3.0
by Raymond Hettinger Sept. 8, 2008

Sept. 8, 2008

I think this should be deferred to Py3.1. This decision was not widely discussed and I think it likely that some users will be surprised and dismayed. The release candidate seems to be the wrong time to yank this out (in part because of the surprise factor) and in part because I think the change silently affects shelve performance so that the impact may be significantly negative but not readily apparent. We don't have to take this out. So why do it hastily at the last minute and without some discussion on comp.lang.python at least. If it were any other release, we would have disciplined ourselves to deprecate first and remove a generation or two later. Also, the reason for removal may yet disappear if jcrea steps in an continues to make updates. Also, the referenced note ( http://mail.python.org/pipermail/python-dev/2008-July/081379.html ) say to "start end-of-lifing it" which I took to mean deprecate rather than remove during a release candidate.

constness of interpreter data
by Torne Wuff Sept. 8, 2008

Sept. 8, 2008

libpython2.5.a contains quite a lot of .data that doesn't look like it needs to be writable (my minimal interpreter binary has 105KB of writable allocated data). A lot of these symbols look like they could just be tagged const with no other changes to the interpreter; some of them would require a proliferation of constness. I'm a bit new at this, though, and it's possible that I'm wrong about some/most/all of these, so I'm wondering what people think. Attached is a patch which adds const to the easy ones: * Docstrings for extension functions (PyDoc_VAR in Python.h) * ascii->digit lookup table (_PyLong_DigitValue in longobject.c) * The copyright notice (cprt in getcopyright.c) There are no errors or new warnings introduced in my build by this patch, but I'm only compiling the interpreter itself. If anyone can suggest a reason why any of those shouldn't be const, please do :) Things that take up space that might be const-able with more effort, or might not, I can't tell: * Token names (_PyParser_TokenNames in tokenizer.c) * Module function tables (and ensuing propagation of constness into PyModule_Init etc) * All the type and exception objects Things that take up space but probably aren't const-able unless someone who knows more than me has an idea: * Standard slot definitions (slotdefs in typeobject.c, but the interned string pointers get added at runtime) * The generated tables for the grammar (but the accelerator seems to want to change these at init time) There's probably other things, but I didn't go through the entire symbol table, just started with the big ones :) So, er, is this a remotely sane thing to be doing, and does anyone have suggestions? :) -- Torne Wuff torne(a)wolfpuppy.org.uk
