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

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

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 7 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.
comment:19 Changed 7 years ago by
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...
comment:37 Changed 6 years ago by
Quick workaround:
ecl_eval("(defprop $LI 210 rbp)") ecl_eval("(defprop $PSI 210 rbp)")
it certainly avoids the extra parentheses around li
and psi
invocations. I've reported this workaround on the maxima bugtracker too. Hopefully Robert will comment there about any possible adverse effects. Including these statements in the maxima_calculus initialization in maxima_lib.py
might do the trick (and possibly the change is accepted upstream!)
EDIT: A better and more universal change is probably:
ecl_eval("(defprop MFUNCTION 190 lbp)")
This way it applies to all "MQAPPLY" calls. That could be problematic, of course, but it doesn't seem to be, probably because 190 is still high enough. Things go wrong if you go too low:
sage: maxima_calculus("(a+b)(t)") (b+a)(t) sage: ecl_eval("(defprop MFUNCTION 1 lbp)") <ECL: 1> sage: maxima_calculus("(a+b)(t)") b+a(t)
comment:38 Changed 6 years ago by
Of course, the expression type that gets constructed for li
and psi
is more general:
sage: maxima_calculus("a[1](x)") a[1](x) sage: maxima_calculus("a[1](x)").ecl() <ECL: ((MQAPPLY SIMP) (($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.

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/0001taylor2Avoidblowingthestackwhendiffexpandisn.patch
 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/
