Description (last modified by )
The Sage wrappers around ppl are now superseded by the standalone pplpy (Python/Cython? compatible). This ticket proposes to replace src/sage/libs/ppl.pyx
extension with pplpy. For this, we
 create a new standard package pplpy
 upgrade gmpy2 from optional to standard
 replace the Sage code calling sage/libs/ppl.pyx to call pplpy
 make appropriate deprecation for
sage.libs.ppl
Tarball for pplpy: pplpy0.8.4.tar.gz

comment:8 Changed 3 years ago by
Salut Vincent,
Your branch appears in red which means that there are merge issues (possibly trivial). Would be better to rebase it on the latest beta.
comment:9 followup: ↓ 11 Changed 3 years ago by
1) Pickling should be fixed
 sage: TestSuite(Asso).run() + sage: TestSuite(Asso).run(skip='_test_pickling')
It works with pplpy
used from Python
>>> x = ppl.Variable(0) >>> y = ppl.Variable(1) >>> z = ppl.Variable(2) >>> gs.insert(ppl.point(x+y+2*z)) >>> gs.insert(ppl.point(xy)) >>> gs.insert(ppl.point(z)) >>> P = ppl.C_Polyhedron(gs) >>> import pickle >>> pickle.loads(pickle.dumps(P)) == P True
2) I don't see the point of the function mpz_to_sage_integer
. You can just do [Integer(x) for x in my_mpz_list]
. For example
v_coords = (1,) + tuple(mpz_to_sage_integer(v.coefficients()))
can be replaced by
v_coords = (1,) + tuple(Integer(c) for c in v.coefficients())
Moreover, the name is confusing since the fuction converts a list of mpz integers.
3) Some possible simplifications
 In
ppl_backend.pyx
:
Integer(g.coefficient(Variable(variable))) / Integer(g.divisor())
>
Rational(g.coefficient(Variable(variable)) / g.divisor())
 In
ppl_lattice_polytope.py
:assert Integer(v.divisor()).is_one()
>assert v.divisor() == 1

It will be nice, but coercion for gmpy2 types is required for doing this (#23052).

Where? The first involves a direct call Rational(mpq_type)
and the second comparison between mpz
and Python integer. Which operation is mixing gmpy2 types with Sage types?

You're right, tests failures in ppl_backend.pyx with the suggested code are not coercion related. Forget my previous comment.

And proper deprecation has to be done for sage.libs.ppl
so that a user doing

The aim is not to keep sage.libs.ppl
but to just to have some indirection in the import so that you do not break user's code. As sage.libs.ppl
will not here anymore I do not expect the full doctesuite to pass as it used to be. But the following kind of things should work (and be doctested)
sage: from sage.libs.ppl import Variable, Constraint_System, C_Polyhedron UserWarning: proper deprecation message sage: x = Variable(0) sage: y = Variable(1) sage: cs = Constraint_System() sage: cs.insert(x >= 0) sage: cs.insert(x <= 3) sage: cs.insert(y >= 0) sage: cs.insert(y <= 3) sage: poly_from_constraints = C_Polyhedron(cs)
And the various objects constructed above are of course from pplpy.
You can have a look at other places in the sage code and look for "deprecation" and "lazy_import".
comment:32 Changed 2 years ago by
Well, i spoke with Sebastien L. and if the goal is to let one year for developers to adapt their old code, doing an indirection is not enough. Mainly because pplpy use gmpy2 (some functions return and calls are differents).
Therefore it seems like we should keep sage.libs.ppl
old code with added warnings.

, :class:`~ppl.Polyhedron`
, etc are broken. These should not be sphinx links at all.

It does build documentation if you ask it to. Tough it does not install anything (perhaps it should?). But even with properly installed documentation, I don't see how to make linking work properly.

I don't know what is the way to proceed. See https://gitlab.com/videlec/pplpy/issues/12
For now I would say:
 remove all links in the Sage documentation
 in each relevant module, make a reference to the pplpy development website (https://gitlab.com/videlec/pplpy) and pplpy documentation website (http://www.labri.fr/perso/vdelecro/pplpy/latest/).
comment:99 Changed 10 months ago by
I've left comments in https://gitlab.com/videlec/pplpy/issues/12 namely there appears to be a Sphinx extension to link different projects.
It's too early to start blindly removing links to docs, probably there is a more intelligent way to preserve what is already there.

SAGE_SPKG_INSTALL_DOCS  if set to yes, then install packagespecific documentation to $SAGE_ROOT/local/share/doc/PACKAGE_NAME/ when an spkg is installed. This option may not be supported by all spkgs. Some spkgs might also assume that certain programs are available on the system (for example, latex or pdflatex).

I believe it has been done that way a long time ago when Sage was not thought modular at all. Some of the package documentation (including pplpy) might be automatically installed unless SAGE_SPKG_INSTALL_DOCS is explicitely set to "no".

ef89978
Implements the compilation and installation of pplpy's documentation.
The current implementation drawback is that pplpy is compiled two times (one time for package installation and one time using "inplace" build in preparation for sphinx).
To avoid that i am looking for an elegant and generic way to express PYTHONPATH=$PYTHONPATH:$SAGE_DESTDIR_LOCAL/lib/python2.7/sitepackages
.
I haven't find an environment variable for lib/python2.7/sitepackages
or something equivalent.
Any help is welcomed.

Could you ask about 106 on sagedevel? This is a general problem when a package needs to be installed before being able to build the docs. Perhaps this is a problem with the package itself or in the way our current staged installation works in Sage. But then, it is not clear to me how to solve it.

I managed to replace the doc links of type sage.libs.ppl.*
. But there is no such kind of doclinks under backend_ppl.html
. Class like sage.geometry.polyhedron.base_QQ.Polyhedron_QQ
are still sage classes.

The external tarball can contain extra 200K, sure, but already "just copying" has to be done properly, in order not to break package deinstallation. Besides, there is no guarantee it would look nice enough, so that it matches the current Sage docs style, etc.

Yes, this is the discussion link https://groups.google.com/forum/?#!topic/sagedevel/qoxVng1__0A.
The discussion/objections where more about what types pplpy should return (Sage numbers or gmpy2 numbers).
The last 3 messages for gmpy2 solution have never been answered, but rereading the thread it's true that it doesn't mean that we have an explicit consensus.
I put this ticket on hold in wait for better solution for generating documentation.

the question is  are you prepared to patch pplpy sources? Comparing their docs/Makefile with https://github.com/sagemath/sagenb/blob/master/doc/Makefile seems to say that there are sphinx options one might try to use to do everything in one build, not in two.
comment:134 Changed 10 months ago by
I haven't find a decisive difference between the two Makefile. The most obvious one being that pplpy use sphinxbuild b
and sagenb use sphinxbuild M
.
I have tried with M
and get the same result.
I think the reason it works with sagenb
is because it doesn't have cython files and therefore the source directory is enough for the sphinx build to succeed.

To my knowledge, no package had this problem before (ie building the doc depending on the library being installed). Everything that would avoid modifying PYTHONPATH
looks nicer to me. But that is my own feeling.

How about src/sage/numerical/backends/ppl_backend.pyx ? Do you at least have a ticket to work on replacing this with pplpy?
comment:166 Changed 10 months ago by
ppl_backend.pyx is modified in this ticket. This is not replaced but ppl_backend.pyx
methods use pplpy instead of using sage.lib.ppl.

@Dima tell me if you think it's ok or if you think ppl_backend.pyx
should be reworked in another way.
comment:168 followup: ↓ 169 Changed 10 months ago by
I recall that ppl_backend.pyx had a tricky part due to the inability of PPL to work with rationals  everything had to be integer. I don't know whether this is still the case. Potentially, if it, or/and pplpy can now work directly with rationals, it might be worthwhile to change, as computing common denominators lead to blowup of coefficients.

The PPL Coefficient type is hardcoded in the Cython wrapper as
ctypedef mpz_class PPL_Coefficient
This implies that all computations with pplpy are done with GMP mpz. I agree that PPL supports computations with mpz_class
, mpq_class
as well as various native integer types (from char
to long long
). Nothing has changed on this side yet. This feature request is disjoint from this ticket which aims to be a simple transition from Sage source code to standalone library.

Looking at the diff, I have several minor comments:
 Don't change whitespace in
src/module_list.py
for no good reason.
 In various places, you use
list(...)
. Why not use a list comprehension instead?
 In multiline imports, the preferred style is to use parentheses instead of
\
.
 The deprecation message is really strangely formatted: it shouldn't start with a newline and there shouldn't be a huge amount of indentation in the second line. I would probably write it all on one line without any newlines at all.
 What's the meaning of the
/...
at the start of the deprecation warnings in doctests? I have never seen that.
 In
_add_rational_constraint
, why do youcdef Rational rhs
? Sincenumerator
anddenominator
are pure Python methods, this is a pessimization.

I wonder if there shouldn't be something like this mentioned in the developer docs (do we have a style guide)?
This is a comment I've made in review on dozens of tickets at this point.
Short list comprehensions (it's trickier when they get nested) are often clearer than any alternative, and are usually much more efficient from the Python interpreter's standpoint as well.

One minor comment just looking at the patch: To complement the pplpy/spkgpostinst
script, it would be good, albeit not strictly necessary, to include a pplpy/spkgpostrm
script that removes that documentation directory in its entirety, if it was installed. That way it's a bit tidier if you also remove or upgrade pplpy and its documentation changes.

Basically, at the end of sagespkguninstall

among other things). This is also called when upgrading a package so that's why I thought it might matter eventually, at least in a minor way.

comment:199 Changed 9 months ago by
That was quick, thank you :)
Not sure yet if it's a showstopper, but I'm also having a weird problem with error handling in the gmpy2 in Sage. This following example should raise a TypeError
exception:
$ python c 'import gmpy2; gmpy2.is_fermat_prp(1234, "a")' Aborted (core dumped)
I also built the latest gmpy2 from source, and when I run it in that source tree I get the correct behavior:
$ python c 'import gmpy2; gmpy2.is_fermat_prp(1234, "a")' Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: is_fermat_prp() requires 2 integer arguments
Perhaps it was just a bug in gmpy2 that has since been fixed upstream? Not sure.
comment:200 Changed 9 months ago by
Indeed, that particular bug was already fixed upstream: https://github.com/aleaxit/gmpy/commit/533a62cf2b2cf3673e1d6b0f3c2d0c64548a3908
I just wanted to make sure. I think I only hit on it because I was running the tests from gmpy2's current' master branch against our slightly older version, and hit that bug specifically because they added a regression test when they fixed it. Other than that all spkgcheck
tests pass on Cygwin for gmpy2 and pplpy :)
comment:201 Changed 9 months ago by
All good on my end in terms of Sage doctests, I think. I'm doing one more full run just to be sure but I can think of no reason it should work differently.
So just update to the justreleased pplpy 0.8.4 and you can set back to postive_review. The spkgpostrm would be good to have too but I don't consider it a blocker.

There were several instances of removal similar to self._PPL_C_Polyhedron.set_immutable()

Indeed, it is not supported anymore. Also you can not cache a PPL_C_Polyhedron
: https://gitlab.com/videlec/pplpy/blob/master/ppl/polyhedron.pyx#L86102
In sage, the pplpy polyhedra are only used as attribute from which the user is not supposed to have direct access (unless she knows very well what she is doing). The higher level Polyhedron_base
still implements this mutability flag.
Could you give a concrete example of a problematic behavior?
comment:215 Changed 9 months ago by
Well I don't have an example from "real life" given that these objects used to be immutable and that I generally knew what I am doing, but the situation I have described is not at all impossible. Although the method returning PPL representation is underscored. There is also a discrepancy with documentation at https://github.com/sagemath/sage/blob/develop/src/sage/geometry/cone.py#L1373 which claims that supplied polytope will be made immutable.
