issue #2937. This information can be helpful for diagnosing platform-
specific problems in math and cmath. The result of the test also
serves as a fairly reliable indicator of whether the x87 floating-point
instructions (as opposed to SSE2) are in use on Intel x86/x86_64 systems.
that may be required when linking against readline. This fixes issues
with x86_64 builds on some platforms (at least a few Linux flavors as
well as OpenBSD/amd64).
to get the correct completion_matches function to avoid crashes on
x86_64 (amd64).
I don't have OpenBSD to test myself. I tested that it does not break
anything on linux. It is simple.
This patch adds a new configure argument on OSX:
--with-universal-archs=[32-bit|64-bit|all]
When used with the --enable-universalsdk option this controls which
CPU architectures are includes in the framework. The default is 32-bit,
meaning i386 and ppc. The most useful alternative is 'all', which includes
all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64).
This includes limited support for the Carbon bindings in 64-bit mode as well,
limited because (a) I haven't done extensive testing and (b) a large portion
of the Carbon API's aren't available in 64-bit mode anyway.
I've also duplicated a feature of Apple's build of python: setting the
environment variable 'ARCHFLAGS' controls the '-arch' flags used for building
extensions using distutils.
information about the processor on the Debian/alpha
buildbot. (I'm still trying to track down the cause
of the test_math failures for this machine.) This
checkin will be reverted within the next 48 hours.
This introduces a new configure option: --with-framework-name=NAME
(defaulting to 'Python'). This allows you to install several copies
of the Python framework with different names (such as a normal build
and a debug build).
the compiler. This should(?) help to fix failures in test_math
and test_cmath on Linux/alpha.
Also add configure message reporting the result of uname -m, as
a debugging aid.
apparently because tanh(-0.) loses the sign of zero on that platform.
If true, this is a bug in FreeBSD.
Added a configure test to verify this. I still need to figure out
how best to deal with this failure.
The patch adds wrappers for the Linux epoll syscalls and the BSD kqueue syscalls. Thanks to Thomas Herve and the Twisted people for their support and help.
TODO: Finish documentation documentation
-no-cpp-precomp, and -mno-fused-madd from configure.
* r22183 added -no-cpp-precomp, which
http://gcc.gnu.org/ml/gcc/2005-12/msg00368.html claims hasn't been
needed since gcc-3.1.
* r25607 added -Wno-long-double to avoid a warning in
Include/objimpl.h (issue 525481). The long double is still there,
but OSX 10.4's gcc no longer warns about it.
* r33666 fixed issue 775892 on OSX 10.3 by adding -mno-fused-madd,
which changed the sign of some float 0s. Tim Peters said it wasn't
a real issue anyway, and it no longer causes test failures.
Fixes issue #1779871.
The bundled libffi copy is now in sync with the recently released
libffi3.0.4 version, apart from some small changes to
Modules/_ctypes/libffi/configure.ac.
I gave up on using libffi3 files on os x.
Instead, static configuration with files from pyobjc is used.
Georg Brandl has added fchmod() and fchown(). I've contributed lchown but I'm not able to test it on Linux. However it should be available on Mac and some other flavors of Unix.
I've made a quick test of fchmod() and fchown() on my system. They are working as expected.
In addition to testing positive numbers, verify negative numbers work in configure.
In order to avoid compiler warnings on OS X 10.4, also change the order of the check
for the format character to use (PY_FORMAT_SIZE_T) in the sprintf format
for Py_ssize_t. This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't
defined at configure time. Need to verify the buildbot results.
Backport candidate (if everyone thinks this patch can't be improved).
configure uses similar compiler flags as setup.py when doing the zlib test.
Without this patch configure would use the first shared library on the linker
path, with this patch it uses the first shared or static library on that path
just like setup.py.
with --enable-framework
* Also for --enable-framework: allow users to use --prefix to specify
the location of the compatibility symlinks (such as /usr/local/bin/python)
target. Until now users had to use 'make frameworkinstall'
to install python when it is configured with '--enable-framework'.
This tends to confuse users that don't hunt for readme files
hidden in platform specific directories :-)
* Don't use xcodebuild for building PythonLauncher, but use a normal unix
makefile. This makes it a lot easier to use the same build flags as for the
rest of python (e.g. make a universal version of python launcher)
* Convert the mac makefile-s to makefile.in-s and use configure to set makefile
variables instead of forwarding them as command-line arguments
* Add a C version of pythonw, that we you can use '#!/usr/local/bin/pythonw'
* Build IDLE.app using bundlebuilder instead of BuildApplet, that will allow
easier modification of the bundle contents later on.
bug. I don't understand this at all, but Darwin/[78].* gets converted
to Darwin/78.* which is not correct. Maybe I'm just clueless or overworked.
I can't see why in the original checkin this should have changed.
This hack gets the Mac build working again. If someone figures out the
real problem, please revert this and fix for real.
Anthony is telling me that AC_PROG_CXX_WORKS which we use is broken.
I have no idea if that's related.
This change breaks up the case and fixes a typo.
gcc. Without this flag, doing pretty much anything with NaNs causes
a Floating Point Exception signal. This causes the interpreter to quit.
The failing tests this fixes are: test_float, test_long, and test_struct.
This is somewhat equivalent to doing signal(SIGFPE, SIG_IGN).
Will verify if this is a problem in 2.4 and backport if necessary (probably).
