Even more prerelease Python fun on Windows!
by Tim Peters Sept. 4, 2000

Sept. 4, 2000

As below, except the new file is /pub/windows/beopen-python2b1p2-20000901.exe 5,783,115 bytes still from anonymous FTP at python.beopen.com. The p1 version has been removed. + test_popen2 should work on Windows 2000 now (turned out that, as feared, MS "more" doesn't work the same way across Windows flavors). + Minor changes to the installer. + New LICENSE.txt and README.txt in the root of your Python installation. + Whatever other bugfixes people committed in the 8 hours … [View More]since 2b1p1 was built. Thanks for the help so far! We've learned that things are generally working well, on Windows 2000 the correct one of "admin" or "non-admin" install works & is correctly triggered by whether the user has admin privileges, and that Thomas's Win98FE suffers infinitely more blue-screen deaths than Tim's Win98SE ever did <wink>. Haven't heard from anyone on Win95, Windows Me, or Windows NT yet. And I'm downright eager to ignore Win64 for now. -----Original Message----- Sent: Friday, September 01, 2000 7:35 AM To: PythonDev; Audun.Runde(a)sas.com Cc: audun(a)mindspring.com Subject: [Python-Dev] Prerelease Python fun on Windows! 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 we hope all for the better. Points of particular interest: + I'm running a Win98SE laptop. The install works great for me. How about NT? 2000? 95? ME? Win64 <shudder>? + For the first time ever, the Windows installer should *not* require adminstrator privileges under NT or 2000. This is untested. If you log in as an adminstrator, it should write Python's registry info under HKEY_LOCAL_MACHINE. If not an adminstrator, it should pop up an informative message and write the registry info under HKEY_CURRENT_USER instead. Does this work? This prerelease includes a patch from Mark Hammond that makes Python look in HKCU before HKLM (note that that also allows users to override the HKLM settings, if desired). + Try python lib/test/regrtest.py test_socket is expected to fail if you're not on a network, or logged into your ISP, at the time your run the test suite. Otherwise test_socket is expected to pass. All other tests are expected to pass (although, as always, a number of Unix-specific tests should get skipped). + Get into a DOS-box Python, and try import Tkinter Tkinter._test() This installation of Python should not interfere with, or be damaged by, any other installation of Tcl/Tk you happen to have lying around. This is also the first time we're using Tcl/Tk 8.3.2, and that needs wider testing too. + If the Tkinter test worked, try IDLE! Start -> Programs -> Python20 -> IDLE. + There is no time limit on this installation. But if you use it for more than 30 days, you're going to have to ask us to pay you <wink>. windows!-it's-not-just-for-breakfast-anymore-ly y'rs - tim _______________________________________________ Python-Dev mailing list Python-Dev(a)python.org http://www.python.org/mailman/listinfo/python-dev [View Less]

Sounds like a lot of work to me. The pthread library gets us two things (essentially) - a function to create threads, which you could pretty easily replace with clone(), and other functions to handle mutexes and conditions. If you replace pthread_create with clone you have a lot of work to do to … [View More]

Thread problems on Linux
by Charles G Waldman Sept. 4, 2000

Sept. 4, 2000

No, I still don't have the answer, but I came across a very interesting bit in the `info' files for glibc-2.1.3. Under a heading "Specific Advice for Linux Systems", along with a bunch of info about installing glibc, is this gem: > You cannot use `nscd' with 2.0 kernels, due to bugs in the > kernel-side thread support. `nscd' happens to hit these bugs > particularly hard, but you might have problems with any threaded > program. Now, they are talking about 2.0 and I assume … [View More]

sorry for the mail sent as "root" - d'oh. I still am not able to send mail from fnal.gov to python.org (no route to host) and am playing some screwy games to get my mail delivered.

ME so mmap
by Tim Peters Sept. 4, 2000

Sept. 4, 2000

Audun S. Runde mailto:audun@mindspring.com wins a Fabulous Prize for being our first Windows ME tester! Also our only, and I think he should get another prize just for that. The good news is that the creaky old Wise installer worked. The bad news is that we've got a Windows-ME-specific std test failure, in test_mmap. This is from the installer available via anonymous FTP from python.beopen.com, /pub/windows/beopen-python2b1p2-20000901.exe 5,783,115 bytes and here's the meat of … [View More]

New commands to display license, credits, copyright info
by Guido van Rossum Sept. 3, 2000

Sept. 3, 2000

The copyright in 2.0 will be 5 or 6 lines (three copyright statements, with an "All Rights Reserved" for each -- according to CNRI's wishes). This will cause a lot of scrolling at the start of a session. Does anyone care? Bob Weiner (my boss at BeOpen) suggested that we could add commands to display such information instead. Here's a typical suggestion with his idea implemented: Python 2.0b1 (#134, Sep 3 2000, 10:04:03) [GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on … [View More]

libdb on by default, but no db.h
by Vladimir.Marangozov＠inrialpes.fr Sept. 3, 2000

Sept. 3, 2000

On my AIX combo, configure assumes --with-libdb (yes) but reports that ... checking for db_185.h... no checking for db.h... no ... This leaves the bsddbmodule enabled but it can't compile, obviously. So this needs to be fixed ASAP. -- Vladimir MARANGOZOV | Vladimir.Marangozov(a)inrialpes.fr http://sirac.inrialpes.fr/~marangoz | tel:(+33-4)76615277 fax:76615252

I am utterly unable to reproduce this. With "ulimit -s unlimited" and a no-threads version of Python, "find_recursionlimit" ran overnight on my system and got up to a recursion depth of 98,400 before I killed it off.
