Hello,
I have been trying to chase down some bug this weekend, but so far
nothing productive has come up.
Problems (short version):
- matplotlib dll load problem - for details see below
- libsingular dll load problem: known issue - Martin Albrecht is
looking into this
- sympow doesn't work - known issue
- real_rqdf doesn't work - known issue
- some problems with pari - know issue - for details see below
- problems with calculus.py - new issue - for details see below
Some details:
--------------------------------------------------------------------
calculus.py:
This one has been around and is a whitespace issue:
sage -t devel/sage-main/sage/calculus/calculus.py
**********************************************************************
File "calculus.py", line 439:
sage: f.display2d(onscreen=False)
Expected:
'\t\t\t\t\t 3\r\n\t\t\t\t y + x\r\n \t\t\t ------------
\r\n\t\t\t
\t 2\r\n\t\t\t\t 3 y + x + 1'
Got:
'\t\t\t\t\t 3\r\r\n\t\t\t\t y + x\r\r\n \t\t\t
------------\r\r\n
\t\t\t\t 2\r\r\n\t\t\t\t 3 y + x + 1'
**********************************************************************
This one is new since 2.5rc2:
sage -t devel/sage-main/sage/calculus/tests.py
**********************************************************************
File "tests.py", line 197:
sage: function('f, g')
Expected nothing
Got:
(f, g)
**********************************************************************
File "tests.py", line 198:
sage: diff(f(t)*g(t),t)
Expected:
f(x)*diff(g(x), x, 1) + g(x)*diff(f(x), x, 1)
Got:
f(t)*diff(g(t), t, 1) + g(t)*diff(f(t), t, 1)
**********************************************************************
1 items had failures:
2 of 77 in __main__.example_0
***Test Failed*** 2 failures.
--------------------------------------------------------------------
Pari:
sage: EllipticCurve(GF(10007),
[1,2,3,4,5]).cardinality(algorithm='sea')
sage: EllipticCurve(GF(next_prime(10**20)),
[1,2,3,4,5]).cardinality(algorithm='sea')
segfaults. According to William that is a know pari issue on cygwin.
This one is new:
In File "ell_rational_field.py"
RuntimeError: Unable to start pari because the command 'gp --emacs
--fast --quiet --stacksize 10000000' failed.
The stacksize seem unreasonable large (~10mb) - any idea why?
--------------------------------------------------------------------
matplotlib
Am I the only one seeing this? I didn't see any reports on sage-*, but
both my XP as well as my W2K installation exhibit this problem. This
was not an issue
python.exe: *** fatal error - unable to remap E:\cygwin\bin\sage-2.5-
cygwin-ms_windows-i686-CYGWIN_NT-5.1\local\lib\python2.5\site-packages
\matplotlib\_ns_image.dll to same address as parent(0x1AEC0000) !=
0x1B100000
propsed solution:
[EMAIL PROTECTED] /bin/sage-2.5-cygwin-ms_windows-i686-
CYGWIN_NT-5.1/local/
lib/python2.5/site-packages/matplotlib
$ rebase -v -b 0x1B100000 _ns_image.dll
_ns_image.dll: new base = 1b100000, new size = 1f0000
But, no luck, after rebasing _ns_image.dll I get another failure by a
test that used to pass:
E:\cygwin\bin\sage-2.5-cygwin-ms_windows-i686-CYGWIN_NT-5.1\local\bin
\python.exe: *** fatal error - unable to remap E:\cygwin\bin\sage-2.5-
cygwin-ms_windows-i686-CYGWIN_NT-5.1\local\lib\python2.5\site-packages
\matplotlib\_ns_image.dll to same address as parent(0x1BFB0000) !=
0x1C1F0000
I tried rebasing the whole SAGE tree, but let's just say that didn't
work particularly well ;)
Cheers,
Michael
