New description:
The new doctesting framework (#12415) on Solaris gives lots of warnings
like
{{{
sage -t --long devel/sage/sage/plot/plot.py
**********************************************************************
File "devel/sage/sage/plot/plot.py", line 236, in sage.plot.plot
Failed example:
(g1+g2).show(ticks=pi/6, tick_formatter=pi) # show their sum, nicely
formatted
Expected nothing
Got:
Warning: invalid value encountered in isinf
Warning: invalid value encountered in isinf
Warning: invalid value encountered in isinf
[...]
Warning: invalid value encountered in isinf
Warning: invalid value encountered in isinf
Warning: invalid value encountered in isinf
}}}
These warnings are actually harmless and are indirectly caused by the fact
that Python doesn't find the `isinf()` C library function. From
`spkg/logs/python-2.7.3.p5.log`:
{{{
[...]
checking whether isinf is declared... no
checking whether isnan is declared... yes
checking whether isfinite is declared... no
[...]
}}}
These functions are defined by C99 and Python's `configure` does find
`isinf` and `isfinite` when compiled with -D__C99FEATURES__. So we should
add a compiler flag to fix this.
'''spkg''':
[http://boxen.math.washington.edu/home/jdemeyer/spkg/python-2.7.3.p6.spkg]
To test: build this spkg, rebuild numpy (optionally: rebuild everything
which depends on Python, including the Sage library).
=== python-2.7.3.p6 (Jeroen Demeyer, 24 March 2013) ===
* Trac #14265: Compile with -D__C99FEATURES__ on Solaris.
* Remove workaround for http://bugs.python.org/issue6954
(which is fixed upstream).
* Rename environment variable EXTRAFLAGS to PYTHON_CONFIGURE for
consistency with other packages and allow it to be set by the user.
* Add check that the ctypes and readline (required for IPython) and
socket (required for setuptools) modules can be imported.
* Don't add the -fwrapv flag (no longer needed since Python-2.7.3 adds
this flag for Clang).
