Idle still has it's own NEWS.txt file, and it's own version number (for instance, 2.3.1's version of idle is "1.0.1". Does this make sense? What should happen for 2.3.2, where no idle changes have been made? Anthony

RE: [Python-checkins] python/dist/src/Tools/scripts md5sum.py, 1.3, 1.3.8.1

I don't know that it ever is. md5sum.py before 2.3 didn't have such an option, and always used binary mode. md5sum.py in 2.3 suddenly grew this option, and *defaulted* to text mode, which is a disaster for normal usage on Windows. On the CVS head I switched the default back to binary mode, but left -t in since we had released a version supporting a -t option (and as the default, no less). I can invent a use case for -t (a text file checksum independent of platform line-end convention), but it's strained (it's never been a real use case in my protracted life <wink>).

PC/python_nt.rc
by Thomas Heller 29 Sep '03

29 Sep '03

The file PC/python_nt.rc defines the version information which will be embedded as resource in pythonXX.dll. Because of limitations in MS resource compiler, the info cannot be constructed from patchlevel.h at compile time, instead it must be changed manually. There is a python script PC/field3.py which helps, but it cannot be used by the build process because python is then not available. I'm working on a way to automate this: A new project is inserted into the MSVC project file, and the pythoncore project (which builds the python dll) will depend on it, so this new project is built first. This new project builds a small exe which will create (as custom build step) an include file for python_nt.rc, so no manual step is needed any more. Does this sound like a sensible approach, or are there any objections? Thomas

Re:coping with a missing fsync
by Scott David Daniels 28 Sep '03

28 Sep '03

After seeing: >backup kept screwing up until FileStorage's > > if fsync is not None: fsync(file.fileno()) > >actually did something on Windows. > I suspect making the change where you obtain fsync, rather than where you call it makes the code clearer. Just after import os, you can do the appropriate bit of the following code: try: fsync = os.fsync except AttributeError: fsync = lambda filenumber: None # Unfortunately nothing to call -------- or -------- fsync = os.fsync or lambda filenumber: None # if we cannot sync, do nothing This (at least to me) emphasizes the lack of a system facility. The existing code emphasizes local solutions on a case-by-case basis. If the solution is always to skip the call, I'd find this method clearer. -Scott Daid Daniels Scott.Daniels(a)Acm.Org

How to test for stuff like fsync?
by Skip Montanaro 27 Sep '03

27 Sep '03

When I checked in the HAVE_SYNC -> HAVE_FSYNC change I thought briefly about including a test to test_os.py. I eventually decided against it because it was clear that a simpleminded test for os.fsync's existence was useless. Jason seems to have been bitten badly by it. I doubt that fsync() is available everywhere (otherwise why test for it in the configure script?), so it seems that Jason should have been testing for its presence (though see below) and worming around its abscence if he wanted TMDA to run on as many platforms as possible. This suggests the following questions: * Is there a reasonable way to write tests which will detect this sort of error? * Should there be special documentation about os-dependent functions which are not universally available? The fsync() doc says nothing about it not always being available (thus Jason can be forgiven for not calling hasattr(os, "fsync")). Skip

plans for 2.3.2
by Anthony Baxter 27 Sep '03

27 Sep '03

Ok, here's my plans for 2.3.2. Cut a release candidate on Tuesday (AU time, so Monday for merkins) Cut a release Thursday (AU time). I don't think the additional two days will hurt that badly, and I'd strongly prefer to have a release candidate before the final build. I don't know if the RC needs a windows installer built, as the problems are in non-windows platforms. Anthony
