Description (last modified by )
Attached patch allows embedding Python tuples in symbolic expressions:
sage: t = SR._force_tuple((1, 2, x, x+1, x+2)) sage: t (1, 2, x, x + 1, x + 2) sage: t.subs(x = 2*x^2) (1, 2, 2*x^2, 2*x^2 + 1, 2*x^2 + 2) sage: t.op[0] 1 sage: t.op[2] x
Includes pynac 0.3.2 update for explicit template instantiatitons

Replying to vbraun:
We were discussing an optional
recursive=[TrueFalse]
keyword argument at SD48. Are you still going to implement this?
I replaced the attached patch. New version supports recursive=[TrueFalse]
.

Hmm... this works for me with sage5.13.beta2
on Ubuntu 12.04 LTS, 32bit with a AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ x2. Also it works for the patchbot(s) running x86_64 architectures. This might also work now since I think we've upgraded cython between now and the last time this was tested... So I'm going to set this back to positive review.

comment:12 Changed 6 years ago by
I suspect that this is a case of http://gcc.gnu.org/faq.html#dso
You can't (without wonky workarounds) use RTTI across shared libraries. We instantiate GiNaC templates in Sage, and std::dynamic_cast
does not consider those the same as instantiations in the pynac shared library. Toughts?
comment:13 Changed 6 years ago by
Possibly, but why does it only seem to fail on that specific machine? I would think if that really were the case, then it should fail across different machines, or at least different versions of Ubuntu...
comment:14 Changed 6 years ago by
Some compiler/linker combination may leave unused instantiations around, or instantiate too much. Its possible to only be triggered on some machines...

comment:17 Changed 6 years ago by
Afaik nothing changed, so it'll still fail on Sparc. If you want to help we can get you an account. Or start a post on sagedevel to remove Sparc from the list of firstclass supported platforms. IMHO it would be way more useful to spend time on ARM and POWER7 than on a longdead platform that is plagued by linker bugs.

But as I'm looking at this ticket, I see redhawk

So was the problem occuring on another machine? (mark?)
comment:20 Changed 6 years ago by
So, rereading this, it was *not on a Sparc machine but a specific Ubuntu one. Can someone test this on a new Ubuntu installation? If it works then even if another specific Ubuntu version fails there should not be anything holding up this ticket any longer.
comment:21 Changed 6 years ago by
From comment:8, the Ubuntu version is the LTS one from 4 years ago. There's been one two years ago and will be a new one next month, so I would be in favor of ignoring the redhawk problem (and maybe update the system there to 12.04, or even 14.04 when its out).
comment:22 Changed 6 years ago by
Just for what it's worth, could you try adding
import ctypes flags = sys.getdlopenflags() sys.setdlopenflags(flags  ctypes.RTLD_GLOBAL)
to src/sage/all.py
and retest on redhawk
?

Yeah, I guess it could have been expected and that it is not a completely random choice that Python does not set it by default as it might expect to load a bunch of libraries and get symbols conflicts. Though the fact that it is set by default on Darwin does not really point in that direction...
What about linking sage/symbolic/ring.pyx/so with libpynac.so? that is modify module_list.py to achieve that.

Building with SAGE_INSTALL_GCC
seems to work... do we have a simple way to shitlist certain compilers by now?
comment:26 Changed 6 years ago by
I think so, look into the magic which decides when to automatically install GCC in `build/install`.
Some combinations are already "forbidden".

Did you try the linking trick? It seems I have access to redhawk, I'll give it a shot anyway.
comment:30 Changed 6 years ago by
Doesn't change anything. And trying to link libcsage.so with pynac makes sage crash at startup.
comment:31 Changed 6 years ago by
It does already link against libpynac due to the magic
# distutils: libraries = pynac gmp
in ginac.pxd
comment:32 Changed 6 years ago by
I'm playing around with marking the pynac templates external in the Sage library (C++11 feature, but unofficial in gcc for a while now). This is one way to avoid the clash. The problems seems that, on redhawk, GiNaC::exprseq
a.k.a. GiNaC::container<std::vector>
is not completely instantiated inside libpynac.so
:
vbraun@redhawk:~/test/pynac/sage$ readelf sW local/lib/libpynac.so  grep _ZN5GiNaC9containerISt6vectorEC.Ev 2014: 0000000000169620 162 FUNC WEAK DEFAULT 12 _ZN5GiNaC9containerISt6vectorEC2Ev 3594: 0000000000169620 162 FUNC WEAK DEFAULT 12 _ZN5GiNaC9containerISt6vectorEC2Ev
vs. on my laptop:
$ readelf sW local/lib/libpynac.so  grep _ZN5GiNaC9containerISt6vectorEC.Ev 468: 000000000017c46e 147 FUNC WEAK DEFAULT 11 _ZN5GiNaC9containerISt6vectorEC2Ev 7994: 000000000017c46e 147 FUNC WEAK DEFAULT 11 _ZN5GiNaC9containerISt6vectorEC1Ev 4012: 000000000017c46e 147 FUNC WEAK DEFAULT 11 _ZN5GiNaC9containerISt6vectorEC2Ev 5629: 000000000017c46e 147 FUNC WEAK DEFAULT 11 _ZN5GiNaC9containerISt6vectorEC1Ev
If you know gcc name mangling by heart (and I don't blame you if you don't) then the C1
is the full constructor while C2
is only the base object constructor. If you use c++filt
then that distinction is not shown (!).
So after marking that template external in ginac_wrap.h
, Sage still works on my lapop but fails on redhawk since the full constructor is never instantiated. I think we should just push explicit instantiation of all necessary templates into pynac, this will probably fix the bug here.

I had a look at the changes in Sage and in Pynac and both look fine (though I cannot completely ensure that some dark magic use of C++ features could still break the templating stuff).
It also compiles fine and passes long tests on a ppc system.
The only change in my branch is a typo correction.

We were discussing an optional
