2.6 rc1 performance results

by A.M. Kuchling

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

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

-----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

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

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.

?spurious? Timeout in BSDDB under MS Windows

new ssl module is incompatible with servers that drop privileges

by Forest

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

-----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-----
