Description (last modified by )
This update fixes #8729. It also includes the fixes noted in #8645 (so this spkg supersedes the maxima spkg at #8645).
The spkg is up at http://sage.math.washington.edu/home/jason/maxima-5.21.1.spkg
A patch needs to be applied to fix some doctests. In particular, apparently maxima has gotten better at integration.

Just a comment:
=== maxima-5.21.0 (Jason Grout, 20 APR 2009) ===is not in the style of the other items in the changelog, where it would be April 20th, 2009. Actually, it would be April 20th, 2010, but who's counting?
There are no less than three different styles in the other dates in the changelog, so apparently it's okay to have inconsistent date styles, so I did the dates in a much more standard notation. However, I'll change it to spell out April since the date is wrong anyway.

Here are the doctests that are broken for me with this spkg:

I've uploaded a new spkg with the changelog date now the correct date (and formatted as 20 April 2010)

For the doctests that return binomial(n,n) instead of 1, we just have to put an assumption in: assume(n>0)

I had the following problem while trying to install this on Sage 4.4:
; registering #<SYSTEM :MAXIMA 4321148288> as MAXIMA An error occurred during initialization: Unknown keyword :MOVE-HERE. installing Maxima library as /Users/karl-dietercrisman/Desktop/sage-4.4/local/lib/ecl//maxima.fas cp: maxima.fasb: No such file or directory *********************************************************** Failed to install maxima.fasb as a library ***********************************************************
Nonetheless, I get Maxima 5.21.0 in the console, and the various binomial(n,n) errors you mention, so maybe something went right?
comment:8 Changed 11 years ago by
- Summary changed from update maxima to 5.21.0 to update/upgrade maxima to latest upstream (5.21.1)
(1) Now the latest maxima is 5.21.1
(2) This should be done in conjunction with upgrading ECL. See #8808. The maxima in sage-4.4 doesn't build with ecl-10.4.1, but Maxima 5.21.1 *does* build fine on top of ECL-10.4.1.
A new spkg is here (but, again, first install the ECL spkg from #8808 when testing this):

Question: Does this still incorporate the fixes mentioned in the Description? I assume it still needs doctest fixes due to improvements.
comment:11 Changed 11 years ago by
I still get
installing Maxima library as /Users/karl-dietercrisman/Desktop/sage-4.4/local/lib/ecl//maxima.fas cp: maxima.fasb: No such file or directory
though I no longer get the unknown keyword error. maxima_console() does give me 5.21.1. Testing now.

Oops, seems that solving inequalities is completely broken with this new version of Maxima.
comment:14 follow-up: ↓ 36 Changed 11 years ago by
- Status changed from needs_review to needs_work
Yes, though I wouldn't say completely broken, since not every doctest fails, correct?
Other issues:
In symbolic/integration/integral.py, there is one integral which has been improved, and one which seems to affected by the rational approximation thing, but wasn't before. There is also an integral (in that file, I think) which Maxima can now do, and we need to replace it with one Maxima can't do. There is also a slight change in the numeric value because of this, but that wasn't the point of that doctest.
The binomial issue seems easy to fix, but apparently now binomial(n,n)=1 for all n in Sage, but not in Maxima. Should we change Sage, or do what Jason recommends (assume n>0 or something)?
And in interfaces/maxima.py there are a lot of erros where Maxima loads like
;;; Loading #P".../local/lib/ecl/cmp.fas" ;;; Loading #P".../local/lib/ecl/sysfun.lsp"
as well as of course the Maxima version being wrong and, oddly, the following:
sage: maxima.eval('sage0: x == x;') Expected <Error> Got: 'x'
which is not good at all if real, but maybe just means Maxima changed something minor?
The plot3d one is not too significant, I think. I haven't looked at the other ones.
Anyway, obviously 'needs work' until someone posts a fairly comprehensive patch.
comment:15 Changed 11 years ago by
Also, the spkg-install for the most recent spkg does not include the fix from #8645, as opposed to the one Jason posted. That is crucial to close this ticket.

I couldn't find a way to double-check that the new answer is correct in the following output mismatch

The next doctest is testing that #780 is fixed. Here, it appears that #780 is *not* fixed again. However, the actual maxima bug that was fixed for #780 is still fixed. The problem seems to be that we use keepfloat: true, and when we have keepfloat: true, the erroneous question pops up.

There is some output mismatch in transform.pyx. This occurs in an explanatory section of the docs, and just consists of simplifying a horrendous matrix. The matrix just simplifies differently now (we get explicit imaginary values now, for some reason). Does anyone want to check that the simplifications are actually correct now?

Thanks for the comprehensive report; I had my own private list of these from a few weeks ago, but had not had time to look into all of them yet.
I think with the last two things there must have been internal changes in Maxima which lead to different handling - in particular, that gcd must now load some modules? I'm going to check what maxima_console() does with these things.

Well, I wouldn't be surprised if those extra lines actually came from the updated ECL package, given what the messages are.

Hmm, maybe ECL does something not silently it did silently before? I forgot I had to install that spkg, by the way - to all others, remember to use #8808 first!
comment:26 Changed 11 years ago by
With the new ECL and the new Maxima, I no longer get the error messages about installing a .fas or .fasb file. That is good.
Anyway, doctest should just be changed for the loading thing, regardless of where it does it. All documentation requests do that, as does running maxima_console(). Unless... before, maxima_console() gave three loading statements, the last two of which are the ones which show up in your examples. Now there are five, but the top two are new... are we stripping away three load statements in the output, but not more? Just a wild idea.
As for the last error, here it is in the maxima_console() - something's not going right.

Regarding the other errors:
Replying to jason:
The doctests that still fail after the patch is applied (under ptestlong) are listed below:
I couldn't find a way to double-check that the new answer is correct in the following output mismatch

This is true if the cosine integral ci(x) (Ci in Mma) is 1/2*(Ei(I*x)+Ei(-I*x). Several online references imply it, and also noting that cos(x) is 1/2*(exp(i*x)+exp(-i*x)) (by Taylor series or whatever you like) suffices.
Here is a maxima session (5.21.1) showing the problem. When keepfloat is false, an integral comes right back

I'm not sure what to do with this. keepfloat is so annoying.
There is some output mismatch in transform.pyx. This occurs in an explanatory section of the docs, and just consists of simplifying a horrendous matrix. The matrix just simplifies differently now (we get explicit imaginary values now, for some reason). Does anyone want to check that the simplifications are actually correct now?

I believe this is all related to a change made in how sqrt behaves with respect to factors (sqrt(ab) and sqrt(a), sqrt(b)) and whether an I gets factored out or not. They all come down to the same essential things:
-(cos(theta) - 1)*sqrt(-x^2 - z^2 + 1)*x -((cos(theta) - 1)*sqrt(-x^2 + 1)*sqrt(-x^2 - z^2 + 1)*x*sqrt(z^(-2))
- sqrt(z^2)*sin(theta) - I*sqrt(x^2 - 1)*sin(theta))*sqrt(z^2)/sqrt(-x^2 + 1)
The latter seems ok immediately (or at least no worse than other decision made for us about which root of -1 to choose), but even given that $x^{2+y}2+z^{2=1$, which is asserted earlier in the file, I can't quite make out the former. I'll look into this a little more. }

Burcin has also already pointed this out at #8624.

I get the following on Mac OSX 10.6 on Intel (see the patch for the which test):
sage: h.n() Expected: 0.075715991017028972 Got: 0.075715991017028958
comment:33 Changed 11 years ago by
That h.n() doctest is interesting. (From what I recall when I investigated it) the old maxima agreed with both mathematica and mpmath, but the new maxima is off in the last few digits---it might be worth checking into, though it may just be numerical error.
comment:34 Changed 11 years ago by
(but those h.n() errors I talked about were for the old sin function, not the new tan function, IIRC)

And in interfaces/maxima.py there are a lot of erros where Maxima loads like
;;; Loading #P".../local/lib/ecl/cmp.fas" ;;; Loading #P".../local/lib/ecl/sysfun.lsp"
It's actually possible to turn messages like this off. If you're driving maxima via a pexpect interface, that might be the proper thing to do. The key is the "Common Lisp HyperSpec?", the de facto official CL documentation. Looking at load
leads to the global variable *load-verbose*
:
http://www.lispworks.com/documentation/HyperSpec/Body/v_ld_prs.htm#STload-verboseST
It's on by default in ECL, but can be turned off:

Should be available real soon now at: http://sourceforge.net/projects/maxima/files/ (looks like the list hasn't been refreshed yet, I don't know what the refresh schedule is) If someone can build & upload a Windows installer that would be great. As ever please give the new version a try and if/when there aren't too many complaints I'll make a general announcement. best Robert Dodier
So maybe we should change this ticket to 5.22.0 if they don't get too many problems with it?
comment:40 Changed 11 years ago by
And now the latest is 5.22.1.
comment:41 Changed 11 years ago by
This will probably also fix #8582.
comment:42 Changed 11 years ago by
Just FYI on this ticket - from an email on the Maxima list by Robert Dodier:
The next release is planned for December, with the release branch (5.23) on Dec 1 or soon thereafter, with a stable release to follow around Christmas.
comment:43 Changed 11 years ago by
As sooner or later maxima would have to be updated to 5.22 or newer I decided to share my experiences of first approach to update to it. I wanted to try 5.22 because it's first version that supports inversion of error function, and first to support integrals of form abs(x) from 0 to a without assumptions. I based on patch by Jason for 5.21 and wanted to reach at least same level of failures as with 5.21. Unfortunately, I got stuck at one place - maxima hangs in some situations. I tracked that to this difference:
before it was

and now it is

(%i1) 0; <sage-display>(%o1) 0 (%i2) sage0: x==x; incorrect syntax: = is not a prefix operator sage0: x== ^
which makes Sage wait for "<sage-display>" forever.
I made spkg: http://lab15.im.pwr.wroc.pl/~giniew/maxima-5.22.1.spkg and patch - http://lab15.im.pwr.wroc.pl/~giniew/trac-8731-maxima-upgrade-to-5.22.1.patch - those are not working but I'm attaching them in case someone wants to pick up from here - as I said I gave up for now.
(btw, the doctest that was failing in devel/sage/sage/calculus/calculus.py is just different grouping, checked it and added new version to doctest, and there is one new doctest failure in devel/sage/sage/calculus/calculus.py that fails because maxima can integrate abs(x) in x from 0 to any a and returns correct 1/2*a*abs(a). There was also change to how logcontract works, they don't make full rational simplification now. I added one more step of rational simplification to simplify_full to simplify it more, though it might change some results.)

See #10187 for up-to-date ecl/maxima spkgs and a workaround to the sage-display
issue.
comment:45 Changed 11 years ago by
- Milestone changed from sage-4.6.1 to sage-duplicate/invalid/wontfix
- Resolution set to duplicate
- Status changed from needs_work to closed
Close as a duplicate of #10187. The latter ticket upgrades Maxima to version 5.22.1.
Just a comment:
is not in the style of the other items in the changelog, where it would be April 20th, 2009. Actually, it would be April 20th, 2010, but who's counting?
