I tried maxima 5.36.0 and reverted (that was with ecl 15.3.7) , not tried 5.36.1 (5.36.0.1 whatever the version number is actually).

The branch is currently not working; to build the new ecl pkg, one has to move patches/implib.patch
out of the way; I tried porting the latter patch to the new ecl, but it produces a makefile error that I don't understand; anyway, it is cygwinspecific.
I cc its author now. J.P., any ideas?

for the record, I get

comment:8 Changed 6 years ago by
What I don't understand is whether some patches are in fact results of running autoconf/automake/aclocal on patched configure.ac, Makefile.in, etc.
If yes, then these should be split from the "real" ones to allow for fully automatic creation (and commands needed to run autotools need to be spelled out somewhere in the pkg docs). If no, then I don't see the point of patching configure.ac, Makefile.in, etc in the first place.

Look at spkg_src. autotools are not run. But may be the impl platch was copied from an autotool run. The gmp patch deals with the removal of gmp sources from the upstream tarball (the configure script of ecl checks for stuff in that subdirectory so those checks have to be diverted). the impl patch deals with cygwin stuff.
Getting real autoconf patch and running autotools wouldn't be a bad idea but that means you will need to have autotools installed to run spkgsrc. spkgsrc will need to be amended accordingly.

I notice that the gmp patch is against configure.ac
while implib is against configure.in
the last one is probably wrong.

No, I mean that it is silly and errorprone to rebase by hand patches that are better obtained directly from diffs to output of autoconf/automake/aclocal.
The latter should not be bundled together with the "real" one.

Sorry I have been too busy today to look further into this. I can reproduce your problem with your branch on my mac. I haven't quite identified yet the guilty makefile. I think the problem is not in the top makefile but in one of the subfolders but I haven't identified which one yet.
comment:18 Changed 6 years ago by
To complete the answer you got from upstream: automake is not used (not a crime) but ecl also ship some of its dependencies in the pristine tarball and those come with their own build systems which can use automake. Apart from ffi
we don't want to care about these I think.

arrghh, that was me mixing of tabs and spaces in src/Makefile.in
patch...
Now all seems to work. I'll post an update soon.
OK, and for the record, src/configure
is generated by autoreconf, that is, one does not need to rebase the corresponding patch manually.

No, it is not very easy to fix. We rewrite li[n](
to polylog(n,
and the same for psi[n](
to psi(n,
. This string matching obviously completely breaks if maxima starts spelling this as (li[n])(x)
. Quite frankly, that's an insane spelling, so perhaps the preferred approach is to clarify with the maxima folks if they really intend this. It might be an unforeseen byproduct of some other change that they prefer to fix themselves, in which case we shouldn't waste time.
If they insist this is a reasonable spelling, I think we can work around it, but it'll be a bit of real work. Note that we can handle calls to parenthesized functions:
sage: from sage.calculus.calculus import symbolic_expression_from_maxima_string as sefms sage: sefms('(sin)(x)') sin(x)
so as long as we ensure that expressions like li[n]
and psi[n]
themselves get parsed to callable functions, we should be OK. Something like this would be OK:
sage: sefms('li[n]') curried_polylog(n) sage: sefms('li[n]')(x) polylog(n,x) sage: sefms('(li[n])(x)') polylog(n,x)
Since we cannot really handle square brackets, we'd need to do the li[n]
>curried_polylog(n)
via a string substitution, but that should be OK. The curried_polylog(n)
would just create a symbolic function that, when called with a single argument, would create the appropriate polylog.
The binary conversion sr_to_max
in maxima_lib.py
shouldn't be affected, unless they have changed their internal representation of polylogarithms.

Robert isn't making any statement there about priority. I would not think it's a very low priority, because the current behaviour is tantamount to writing (sin)(x)
, which is silly. I would not be surprised if in the next couple of weeks, when he has had a chance to think about a solution, he will have a fix. I'm sure it's not hard to fix. It just needs some thought to fix it properly and efficiently.
In terms of total amount of work, I would think introducing "curried" poylog and psi will be less work than eliminating any dependence on string parsing from maxima.
For calculus use, we're already moved entirely to maxima_lib. The library instance just allows two interfaces back and forth: a stringsbased one and the binary sr_to_max
and max_to_sr
one.
Moving calculus entirely to sr_to_max
is a nice idea in general, and that's a worthwhile project that should be quite doable (we're halfway there already and it didn't take much work to do that).
It would mean identifying all remaining places where calculus triggers string conversions and replace those sites with mechanisms comparable to sr_integral, sr_limit, sr_sum etc.
I think it's worthwhile if somehow we do maintain the pexpect interface to maxima as well, even if we don't need it for the calculus functionality in sage proper (and since the stringsbased interface in maxima_lib shares nearly all its code with that, we might as well keep that too). Having the pexpect interfaces in sage is a useful feature for communicating with other computer algebra systems.

he replied, saying that he does not see a way to fix this, and that Sage has to put up with this for the time being.
I'd rather see this fixed im maxima, of course, but this is probably a nontrivial job for a Lisp hacker we don't have...

Quick workaround:
ecl_eval("(defprop $LI 210 rbp)") ecl_eval("(defprop $PSI 210 rbp)")
it certainly avoids the extra parentheses around li
and psi
invocations. I've reported this workaround on the maxima bugtracker too. Hopefully Robert will comment there about any possible adverse effects. Including these statements in the maxima_calculus initialization in maxima_lib.py
might do the trick (and possibly the change is accepted upstream!)
comment:38 Changed 6 years ago by
Of course, the expression type that gets constructed for li
and psi
is more general:
sage: maxima_calculus("a[1](x)") a[1](x) sage: maxima_calculus("a[1](x)").ecl() <ECL: ((MQAPPLY SIMP) (($A SIMP ARRAY) 1) $X)>
but we already fail with that (because we carefully only convert li[
and psi[
):
sage: SR(maxima_calculus("a[1](x)")) TypeError: unable to make sense of Maxima expression 'a[1](x)' in Sage
Since square brackets are really part of Maxima's expression syntax, the proper solution would be to have a parser that can handle them. The following seems valid maxima:
sage: maxima_calculus("(sin(x)+cos(y))[tan(u)[3/(a+b)]+log(w)](t)") (cos(y)+sin(x))[log(w)+tan(u)[3/(b+a)]](t)
and parsing that with anything less than parser support for [
will be. Of course, without []
support on the side of pynac, we'd have to parse a[n]
to something like get_item(a,n)
but that would be fine (and then get_item
can have the right logic to actually resolve in relevant cases, but this would be more an extension of our symbolic expressions before it's a parsing issue for maxima)
comment:39 Changed 6 years ago by
The maxima ticket https://sourceforge.net/p/maxima/bugs/2998/ is now marked as resolved, so with any luck, the extra parentheses issue will not occur with the new maxima release.
The fix implemented is indeed ecl_eval("(defprop MFUNCTION 190 lbp)")
, so if you do not want to wait for the next maxima release, just put this command in the initialization section of maxima_lib
.

 Report Upstream changed from N/A to Not yet reported upstream; Will do shortly.
I tried upgrading to Maxima 5.37.0 (released 17 August). The formatting problem is fixed, although some of the output still looks slightly different (more/fewer parentheses, different ordering of terms in some polynomials).
However, there is a serious bug in the function eigenvectors
causing too few eigenvectors to be returned:
(%i1) M: matrix([1, 1, 0], [0, 1, 0], [0, 0, 2]); [ 1 1 0 ] [ ] (%o1) [ 0 1 0 ] [ ] [ 0 0 2 ]
Maxima 5.35.1 computes the eigenvalues and eigenvectors correctly:
(%i2) eigenvectors(M); (%o2) [[[1, 2], [2, 1]], [[[1, 0, 0]], [[0, 0, 1]]]]
In Maxima 5.37.0, the eigenvector [0, 0, 1]
is missing:
(%i2) eigenvectors(M); (%o2) [[[1, 2], [2, 1]], [[[1, 0, 0]]]]
I found this out through several doctest failures in Sage.

So far, only the relevant commits from the old branch are rebased. I still have to fix patches to Maxima sources  they don't apply cleanly.

We'll also want to move to maxima 5.38.1 at least.

 Work issues changed from rebase the rest of Maxima patches to fix doctests, if any.
comment:55 Changed 5 years ago by
this seems to be a change:
File "src/sage/interfaces/maxima.py", line 210, in sage.interfaces.maxima Failed example: g.taylor('x', 0, 3) Expected: x+x^3/6+(3*x^5)/40+(5*x^7)/112+(35*x^9)/1152 Got: f/(k^4*x^4)(2*f)/((3*k^2)*x^2)+(11*f)/45((62*k^2*f)*x^2)/945
there f
is defined as f=maxima(`1/x^2`)
, so this no longer works, defining maxima
functions this way.
Anyhow, I'm pushing the other doctest changes for this file, and few other.

the following looks to me like a regression (or perhaps it's not really, as if one picked the right branches of the corresponding complex variable functions, it would be correct) :
File "src/sage/calculus/tests.py", line 107, in sage.calculus.tests Failed example: integrate(log(1x^2)/x, x) Expected: 1/2*log(x^2)*log(x^2 + 1) + 1/2*polylog(2, x^2 + 1) Got: log(x)*log(x + 1) + log(x)*log(x + 1) + polylog(2, x + 1) + polylog(2, x + 1)

and another regression of sorts: despite besselexpand
set to False, one gets
File "src/sage/interfaces/maxima_lib.py", line 66, in sage.interfaces.maxima_lib Failed example: sum((x)^n/(factorial(n)*factorial(n+3/2)),n,0,oo) Expected: bessel_J(3/2, 2*sqrt(x))/x^(3/4) Got: 1/2*(2*x*cos(2*sqrt(x))  sqrt(x)*sin(2*sqrt(x)))/(sqrt(pi)*x^2)
Perhaps it's a deficiency of our test, which is too simple for besselexpand
to kick in.

this one needs an expert opinion:

The output is clearly different, but perhaps it's OK, I don't knowI suspect it's OK, as we must be interested in the projective points where it vanishes(?)  documentation talks about "roots" though, and these, projectively, remain the same.

100d9d6 workaround for #<a ARITHMETICERROR> (18920#comment:60
this workaround turned out to be buggy, and anyway ECL has released a fix for this problem, making the workaround not necessary. (But it would need an update of our ECL package, as it does depend upon a number of changes, see https://gitlab.com/embeddablecommonlisp/ecl/issues/299; they promise a new release by the end of the year).
Should we wait, or should we proceed?
comment:72 Changed 5 years ago by
I think we should either backport the fix as a patch to ECL or perhaps take a development cut.

a single patch is not enough. In fact, it hangs the ECL build if I do this. ECL people say the have worked on a number of related things, that is support of IEEE floats, since the release, so the latest fix relies on these. A proper ECL update is the only way I think.

Hi, we're following this ticket very closely in Debian. I notice that the following two patches are still applicable to 5.38.1:

 https://git.sagemath.org/sage.git/tree/build/pkgs/maxima/patches/matrixexp.patch
Have these patches been forwarded upstream yet? Would they be suitable for other users of Maxima, or are they only useful for Sage?

this one comes from upstream, from here: https://sourceforge.net/p/maxima/bugs/2520/#e3a5 (so it's sort of unfinished digging on the maxima side; it's definitely useful outside of Sage)
this is also from upstream (updated somewhat): https://sourceforge.net/p/maxima/bugs/2596/

I think I need an idea what's wrong here, before being able to go forward. This discrepancy between testsuite vs prompt is really odd.

comment:98 followup: ↓ 99 Changed 5 years ago by
here is a bad one  reproducible on two different systems;
I don't understand what's going on here; it appears that computing g(x)
,
the Taylor expansion of log(x)
, breaks log(x)
plotting (in case the leftmost

Replying to dimpase:
here is a bad one  reproducible on two different systems; I don't understand what's going on here; it appears that computing
g(x)
, the Taylor expansion oflog(x)
, breakslog(x)
plotting (in case the leftmost interval point is 0).Probably this initialises some symbolics, breaking handling of infinity in the process...
Further entry point  the crash does not happen if I revert back to ECL 16.1.2.
(and keep new Maxima version).
That is, it seems that the call to taylor
loads ecl+maxima, and sets up some stuff
that is responsible for handling infinities.

I think a number of things point back to ecl16.1.3
so it may belong to #22191. I remember having a lot of similar stuff when changing just ecl
without change maxima
(still need a rebuild though) in sageongentoo. Right now I am just locked on 16.1.2.

still a couple of SIGFPEs to figure out, but otherwise does not look too bad. I'll post ptestlong results later today.
comment:105 Changed 5 years ago by
SIGFPEs are of the same sort as above:
sage: g(x)=taylor(log(x),x,1,6) # this initialises ECL/Maxima sage: q = (2^53) * 2^971/1 sage: float(q) # boom, instead of "inf" as the answer. ... Unhandled SIGFPE: An unhandled floating point exception occurred. ...
which I traced down to the call to ldexp
at sage/rings/rational.pyx:3799
.
Note that this is with ac8348c
commit already in (and so ECL_OPT_TRAP_SIGFPE
= 0), so there is more of the same kind of story as above, but harder. I don't see what's going wrong here now.
This is a different to division by 0 kind of FPE, so this is perhaps the reason.

This latter bug is known, not really a bug and has its own ticket.
Furthermore, Maxima 5.38.1 (Debian testing current version) fixes one of my pet peeves :
charpent@SAP5057241:~$ maxima Maxima 5.38.1 http://maxima.sourceforge.net using Lisp GNU Common Lisp (GCL) GCL 2.6.12 Distributed under the GNU Public License. See the file COPYING.

Whereas Sage's Maxima gives :
charpent@SAP5057241:~$ sage maxima ;;; Loading #P"/usr/local/sage7/local/lib/ecl/sbbsdsockets.fas" ;;; Loading #P"/usr/local/sage7/local/lib/ecl/sockets.fas" ;;; Loading #P"/usr/local/sage7/local/lib/ecl/defsystem.fas" ;;; Loading #P"/usr/local/sage7/local/lib/ecl/cmp.fas" Maxima 5.39.0 http://maxima.sourceforge.net using Lisp ECL 16.1.2 Distributed under the GNU Public License.

To debug this try: debugmode(true);
So, we have :
 already known problems with parallel testing ;
 one already reported and ticketed test failure ;
 one not already reported problem, that continues the previous behaviour of MaximainSage, whereas this behavior has been fixed in 5.38.1.
None of these seem to impede giving this ticket a positive_review
. Which I'd do unless you think that the behavior of the taylor(integrate(...)...)
should/could be fixed with this issue.
However, I think the objection of Thierry Scrim (?) valid, and I think it is more important, since it points out a case where Maxima's answer is incomplete. Hence ==>needs_work
.

Seconded, on basic principles :
[ The following rant is not gratuitous. It's just a lemma. Bear with me for a while... ]
Our "batteries included" socalled philosophy has pushed us to include more and more software of peripheral interest at best up to the point where Sage is now a smallscale, highly specialized Linux distribution.
This distribution is of great interest to sage builders (i. e. potential developpers). It is at best an hindrance (read "pain in the *ss") to what should be one of our primary targets : the potential users of Sage. And no, this cannot be restricted to research mathematicians specializing in number theory...
For example, going to the pain to build our own GCC collection seems to me pushing consistency exigences a bit too far. Requiring from an installer (i. e. potential developper) to take the pain to install a matching set of decently recent compilers does not sound too much to me.
Corollary : our binary tarballs/packages should be sound enough to satisfy the largest possible number of potential users. That means that our users should not be requested to install and manage a virtual machine setup, nor a complicated installation on "exotic" platforms. An undergraduate or even high school student, a practising engineer, etc... should be able to install a precompiled binary and go use Sage as he uses a word processor, without having to install a $#!+load of tools he/she'll never use for anything else.
Therefore, if we need autotools to build Maxima, let's use existing autotools distributions, and do not try to avoid it. Or maintaining our own port. Maintaining our ports should be limited to the cases where there is a mathematical reason to do so.
[ End of rant. Now for its consequences : ]
Therefore, I think that wiggling away from one more tool to build Sage amounts to trying to alleviate the load of developers. Which is the wrong target. Our primary goal should be to alleviate the load imposed on users.
Those two sets were largely overlapping in the begionning of Sage, which as long been targeted on a certain research community. This is no longer the case. Sage now needs a lot of users, able to report problems, if we want to be able to fix them.
So, in the present case, if autotools is needed to build Maxima, let's depend on it for building Sage. But users of a binary distribution of Sage should not have to bother themselves with that.
In other (shorter) words : I'm not bothered by one more build dependency, if I can lighten the run dependencies... This seems the case here.
Corollary : the time spent on arguing and nitpicking over autotools would have been better spent helping Eric Bray's Cygwin port cum Windows installer, which opens us a quite large pool of potential users...
comment:143 followup: ↓ 147 Changed 5 years ago by
autotools are not needed to build Maxima, but makeinfo apparently is.
Perhaps one can build Maxima without makeinfo if autotools are available, I didn't check, for this is even more academic question... makeinfo is a very easy prereq, as it is available on every system we build Sage on, and included in XCode too.

I think this is enough.
I have now reintroduced the makeinfo
workaround and my logs says it is safe to use on a makeinfo
less system.
I appreciate the feeling Emmanuel but the place for it is sagedevel  of course nothing is likely to happen for it in the short term. The reality is now there are plenty of "user space" package management solution around (not so many when sage was started) and most of them do a better job than the sage packaging system. The other reality is those other packaging system usually don't play well with sage. We pick problems regularly from users with a default installation of brew on OS X for example.

So, in the present case, if autotools is needed to build Maxima, let's depend on it for building Sage. But users of a binary distribution of Sage should not have to bother themselves with that.
In other (shorter) words : I'm not bothered by one more build dependency, if I can lighten the run dependencies... This seems the case here.
Users of binary distributions of Sage should still be able to install optional and experimental packages. Since there is no binary distribution of optional packages, buildtime tools need to be included.
I would propose to add a standard package that includes (a current version of) texinfo (which provides makeinfo). Note that our autotools spkg packages only an ancient version of texinfo (4.13) (see #21196 for a discussion).

autotools are not needed to build Maxima, but makeinfo apparently is.
It should not be; the bug is that the necessary TeX files are not included in the tarball. Even if the user does not have makeinfo, there should be no problem because the configure script will set $(MAKEINFO) to a command that does nothing. There is at least one place where a Maxima makefile uses makeinfo
instead of $(MAKEINFO)
. In #17514 I fixed this specific one, but I seem to remember another problem of this kind in newer Maxima versions. Anyway, the only way to really fix this is if the Maxima developers make sure that all TeX files are in the distribution.

I have got a funny failing doctest in sageongentoo but I am not completely sure this ticket is responsible (I am testing from the current develop branch of Volker's fork where he is testing this now)
sage t long /usr/lib64/python2.7/sitepackages/sage/functions/special.py ********************************************************************** File "/usr/lib64/python2.7/sitepackages/sage/functions/special.py", line 232, in sage.functions.special.SphericalHarmonic._eval_ Failed example: spherical_harmonic(3,2,1,2*pi/3) Expected: 1/240*sqrt(30)*(15*I*sqrt(7)*sqrt(3)  15*sqrt(7))*cos(1)*sin(1)^2/sqrt(pi) Got: 1/240*sqrt(30)*(15*I*sqrt(7)*sqrt(3) + 15*sqrt(7))*cos(1)*sin(1)^2/sqrt(pi) **********************************************************************
As you can see they are actually identical...

Doctest introduced by #20939 merged in 7.6.beta0, that's why it was missed. The branch needs rebasing before it can be fixed. Incoming.

For info, I have been using ecl 15.3.7 for a while in sageongentoo. That part is a straight upgrade as far as I can see. I do not remember having tried a newer maxima but it usually breaks a lest a couple of doctest.
