Should a change in search order of directories in setup.py be backported?
by Brett Cannon Feb. 3, 2008

Feb. 3, 2008

I found out that the directories listed in $CPPFLAGS and $LDFLAGS were being added in reverse order in setup.py. That meant having ``-I/foo -I/bar`` was searching /bar first. I fixed setup.py in the trunk so that the declared order if followed instead. But should this be backported? It will change how extensions are compiled if there is more than one version on a machine. Not sure if we want people to suddenly have what they link against change in a micro release. -Brett

A word of warning against using sqlite3 from MacPorts
by Brett Cannon Feb. 3, 2008

Feb. 3, 2008

I was running the test suite today and I was getting a segfault in test_sqlite. That seemed odd since I had not seen any issues on any buildbots. And running the test independently was fine. Noticing that sqlite 3.5.5 was recently available I had MacPorts update. Unfortunately this didn't fix things. I narrowed things down to running test_ctypes before test_sqlite as the trigger. In order to debug I wanted to use a version of sqlite that I had compiled. So after figuring out which package to download (turned out to be the amalgamation version with shell.c and the included makefile), and discovering a bug in setup.py where directories from CPPFLAGS were being searched in reversed from their declared order, I managed to get a build with my own version and the problem went away. So I suspect that sqlite3 from MacPorts is built in such a way as to cause issues. This on Leopard which might also somehow influence things. -Brett

Python on non IEEE-754 platforms: plea for information.
by Mark Dickinson Feb. 2, 2008

Feb. 2, 2008

A request for information: What non IEEE 754 platforms exist that people care about running Python 2.6, Python 3.0 and higher on? By non IEEE 754 platform, I mean a platform where either the C double is not the usual 64-bit IEEE floating-point format, or where the C double is IEEE format but the platform deviates in major ways from the IEEE 754 specification. There are a few places (mostly in mathmodule.c, cmathmodule.c, floatobject.c, longobject.c) where it's not clear that the code behaves correctly on non-IEEE platforms, and I'm finding it difficult to determine how broken (or not) it is without having a clear idea of what possible unusual floating-point formats might come up. The major non-IEEE floating-point formats that I know of, on big iron, are the VAX, Cray and IBM formats; I believe anything else is too old to worry about. Is this true? The IBM format is particularly troublesome because it's base 16 instead of base 2 (so e.g. multiplying a float by 2 can lose bits), but it appears that recent IBM machines do both IBM format and IEEE format floating-point. I assume that the S-390 buildbots are using the IEEE side---is this true? At the other end of the spectrum are embedded devices and cellphones. Here I have no idea what the situation is at all---any information would be valuable. Mark

Re: [Python-Dev] Upcoming 2.5.2 release
by Jaroslav Pachola Feb. 1, 2008

Feb. 1, 2008

It would be very nice if http://bugs.python.org/issue1692335 fix was included in 2.5.2. The patch exists, have been tested, reviewed by Georg Brandl, who says he needs some other developer to review the patches (there is a separate patch for 2.6). Could please someone look at the issue and help get the problem fixed in 2.5.2.? Regards, Jaroslav Pachola
