Message: 5 Date: Sun, 12 Aug 2012 23:18:05 +0000 (UTC) From: Robert Dodier <robert.dodier@gmail.com> To: maxima@math.utexas.edu Subject: [Maxima] Maxima 5.28.0 release MessageID: <k09djd$dvj$2@dough.gmane.org> Hi, I've created branch5_28 in Git and tagged branch5_28base and 5.28.0. I've created tar.gz, srpm, and rpm's and uploaded them to the SourceForge file manager. (http://sourceforge.net/projects/maxima/files)
The new spkg is for ECL 11 as well as for ECL 12, i.e. ASDFagnostic, along the lines of maxima 5.26.0 at #13860. Moreover it has an upstream patch preventing segfaults. This fixes few tickets.

True. I just opened this in order to have a ticket for it at all; I couldn't find one for 5.27 update alone (as opposed to things noting that 5.27 would fix various things) so I opened this. Feel free to close it if it's a dup.
comment:3 Changed 9 years ago by
No duplicate that I know off. May be an opportunity to update ecl as well, 12.2.1 works well with a few tweaks. 12.7.1 seems to have issues see #12985.

 Summary changed from Upgrade Maxima to 5.28 to Upgrade Maxima to latest upstream release
The newest Maxima is now 5.29. Ugrading ECL is #13324 and hopefully will have positive review soon.

We'll have to make some change to spkginstall when ECL >= 12.12.1 gets in. See http://trac.sagemath.org/sage_trac/ticket/13324#comment:77
I'm waiting for more info from upstream ECL on this change.

Here comes a 5.29.1 spkg at http://boxen.math.washington.edu/home/jpflori/maxima5.29.1.p0.spkg
It builds and runs and passes most tests in sage/calculus on Linux. Some tests fails because Maxima adds ? in some strings in calculus.py.

comment:9 Changed 8 years ago by
Your spkg diff for the readme says that you removed a patch, but I don't see that in the diff. But we track the patches directory, right?
comment:10 Changed 8 years ago by
Yup, I forgot to run hg addremove.
comment:11 Changed 8 years ago by
It also seems Maxima does not integrate sqrt(x + sqrt(x)) anymore, maybe that needs assumptions which were incorectly assumed before, don't want to think about that now.
comment:12 Changed 8 years ago by
Yes, don't worry about this now, as François has put a lot of time into cataloguing things anyway on some sagedevel discussion a while ago.
comment:13 Changed 8 years ago by
Could you provide a link to that discussion?
comment:14 Changed 8 years ago by
No, it's too old, I'm not sure how to find it. It wasn't part of a thread only about this, I think. François, do you remember?
comment:15 Changed 8 years ago by
Haven't tried 5.29.1 only 5.28 after it came out. I remember that a number of function now require an extra argument (an assumption) as you have found out. But I haven't looked at it in a long time. I'll check what I can find.
comment:16 Changed 8 years ago by
Actually I haven't done a report on upgrade that break things badly for a little while. You may remember a report from a long time ago. I don't have as much time to write those these days.

Yup 12.12.1 plus 5.29.1. About the name changes I mentioned here and on #13324, I got upstream confimation it was expected and is not a problem, see http://sourceforge.net/mailarchive/message.php?msg_id=30232028
I'd prefer to postpone Unicode and deal with it in let's say #12985, unless it is really trivial.

Got these ones and similar in other places. Everything looked trivial to fix and consisted in:
 version number changes,
 integration which did nothing, surely the assumption stuff we mentioned here,
 trivial simplification which was not done anymore, maybe a call to simplify could fix these,
 the strange ? things.

(I think this was already mentioned on the ECL ticket. Not sure how the new library is supposed to work when it doesn't get installed...)
I also get a couple of new warnings (w.r.t. Maxima 5.26.0 and the old ECL) like

That the build "succeeded" despite of the error is due to a subtle bug in spkginstall
:
... check_error() { if [[ $? ne 0 ]]; then echo >&2 "***********************************************************" echo >&2 "Error:" $@ echo >&2 "***********************************************************" exit 1 fi } ... echo "Now installing the Maxima library as '$ECLLIB/maxima.fas'..." cp f maxima.fasb "$ECLLIB/maxima.fas" check_error "Failed to install '`pwd`/maxima.fasb' as '$ECLLIB/maxima.fas'." ...
The exit status ($?
) tested in check_error()
is that of `pwd`
, not the one we're interested in, namely that of cp
.

The fact that this spkg would not install the maxima library (and the error was undetected) was expected. That is what I meant by "build with latest ECL". And thanks for finding out why the error was undetected!!! And yes the new library file is the maxima.system.fasb. See http://sourceforge.net/mailarchive/message.php?msg_id=30232028 I've not replied yet but I don't think we need to ask more work from upstream adsfbundle. We'll just change the filename in spkginstall.
The makeinfo thing reminds me of something. It should definitely not be required. I think the solution was to touch some files, but I guess something changed in Maxima and the file we touch are not sufficient now.

I just manually copied maxima.system.fasb
to $SAGE_LOCAL/lib/ecl/maxima.fas
, hoping that this was correct. (Currently running ptestlong
with Sage 5.5.rc0 on Ubuntu 10.04.4 x86, i.e., an old Pentium4 with currently just 1 GB RAM, which will take ages...)
Or should we keep the new name (.fas
or .fasb
?), probably having to make changes elsewhere?

Presumably yes, I was thinking of the same... (Although IMHO configure
should have checked whether makeinfo
is available in advance, in order to eventually skip a few things later.)
Probably similar for some autotoolsgenerated files, although at least some of the warnings were present in previous spkg logs as well. (I personally don't mind, but these may annoy a few users actually reading or grepping the logs, or watching the build process... We occasionally get "needless" questions regarding such on the IRC.)

I mean the fact that the produced file for Maxima in Lisp libary mode is no longer maxima.fasb but maxima.system.fasb and its not because of the updated Maxima, but of the updated ECL.

I thing we keep maxima.fas as the name of the file in the Sage library ($SAGE_???/lib/ecl/).

Yep,
sage: f = abs(sin(x)) sage: integrate(f, x, 0, 2*pi)
behaves exactly the same, i.e., the interpreter "exits" with a segmentation fault, after thousands of "Detected access to protected memory ..." messages.
(Sage's own signal handler doesn't get called.)

Well, using the Maxima library segfaults.

I can confirm the trouble with integrate(abs(sin(x)))
. It's in the library interface, I reckon.

I get all of these and that last doctest is actually a good thing^{TM} from the file
Note that due to some problems with the way Maxima handles these expressions, definite integrals can sometimes give unexpected results (typically when using inexact endpoints) due to inconsistent branching:: sage: integrate(sinh_integral(x), x, 0, 1/2) cosh(1/2) + 1/2*sinh_integral(1/2) + 1 sage: integrate(sinh_integral(x), x, 0, 1/2).n() # correct 0.125872409703453 sage: integrate(sinh_integral(x), x, 0, 0.5).n() # incorrect! 0.125872409703453 + 1.57079632679490*I
One problem may be fixed here.

Hmmm, I was probably quicker (but I'm leaving it up to you to fix this! :) ):
# Touching html and info files to avoid to regenerate them. # This must be done after configuration since the timestamps need # to be later than includemaxima.texi which is generated at # configuration time: for i in doc/info/*.html ; do touch "${i}" done touch doc/info/maxima.info*
... config.status: creating doc/info/Makefile config.status: creating doc/info/includemaxima.texi config.status: creating doc/info/de/Makefile ...
(The TeXinfo file is created twice, since config.status
gets run when building Maxima as well.)
There are also
maxima5.29.1.p0/src/interfaces/xmaxima/doc/xmaxima.info maxima5.29.1.p0/src/interfaces/emacs/imaxima/imaxima.info
so we should perhaps use
touch `find doc/info name \*.info\*`
or
find doc/info name \*.info\* exec touch {} \;
Using name \*.info\* o name \*.html
in a single statement (instead of the for
loop) would also make sense.

P.S.: Now that I've read the comment in spkginstall
... We probably have to "patch" config.status
after configuring Maxima, to avoid "recreation" of the TeXinfo file.

same for 5.1. So I suppose this is a bug in Maxima 5.26, which remained in 5.29. Oh dear. Both 5.26 and 5.29 give the following nonsense:
sage: from sage.symbolic.integration.external import maxima_integrator sage: g(x)=maxima_integrator(abs(cos(x)), x); g(x) ((2*sin(x)/((cos(x) + 1)*(sin(x)^2/(cos(x) + 1)^2 + 1))  1)*sgn(sin(x)/(cos(x) + 1)  1)  2)*sgn(sin(x)/(cos(x) + 1) + 1) sage: g(0) 1 sage: g.limit(x=pi) x > 0
This, indeed, one gets 1...
they also both "can" compute maxima_integrator(abs(sin(x)), x)...
sage: g(x)=maxima_integrator(abs(sin(x)), x); g(x) (2*sin(x)*arctan(sin(x)/(cos(x) + 1))/(cos(x) + 1)  log(2))*sgn(1/(cos(x) + 1))*sgn(sin(x)) + log(sin(x)^2/(cos(x) + 1)^2 + 1)*sgn(1/(cos(x) + 1))*sgn(sin(x))  log(2*sin(x)^2/(cos(x) + 1)^2 + 2)*sgn(1/(cos(x) + 1))*sgn(sin(x)) + 2*(sin(x)/((cos(x) + 1)*(sin(x)^2/(cos(x) + 1)^2 + 1)) + arctan(sin(x)/(cos(x) + 1)))*abs(sin(x))/abs(cos(x) + 1) sage: g(0) 0

no, you need to load some stuff, as spelled out at maxima_lib.py
:
init_code = ['display2d : false', 'domain : complex', 'keepfloat : true', 'load(to_poly_solver)', 'load(simplify_sum)', 'load(abs_integrate)']
In maxima, you type in
display2d : false; domain : complex; keepfloat : true; load(to_poly_solver); load(simplify_sum); load(abs_integrate); integrate(abs(sin(x)),x);
to get a symbolic answer. It's weird that the definite integral does not get computed, perhaps due to an uncaught error...

What will you get with the CLISPbased maxima here?
If I try the same on 5.26.0 (from Sage 5.5.rc0 on OSX 10.6.8) , I don't get a segfault; I just get back an unevaluated integral, if I try definite integral, and I get the same (wrong) symbolic expression for the indefinite integral.

Well, presumably we'll never merge a new Maxima without new known bugs (although fixing some old ones), probably even regressions, but I feel a bit uncomfortable with how symbolic integration (using the Maxima library interface) now fails, since Sage actually crashes (without itself catching the segfault).
(Others may say that's better than "silently" giving a wrong answer... ;) )
We could mark the doctest # not tested
for now, but who knows where else similar can or will happen.

We should probably fix that in sage/interfaces/maxima_lib.py

Though I didn't know how to run a Maxima command in this, the fact that no error was raised seems good.

 Report Upstream changed from Reported upstream. No feedback yet. to Reported upstream. Developers acknowledge bug.
there is quite a bit of activity on maxima's tracker on the reported bug. There seem to be several(?) bugs triggered, not in abs_integrate package, but in the "core" maxima.
comment:81 Changed 8 years ago by
Anybody a clue where the extra question mark (in e.g. "Is a an ?integer?") may originate from?
I don't get it with sage maxima
.
comment:82 followup: ↓ 83 Changed 8 years ago by
I guess the string produced by Maxima and the way it is treated before printing changed, so the way we do it in maxima_lib at the lisp level is not uptodate anymore?

Ahem, yes, presumably... ;) [AFAICS the original retrieve
function hasn't changed.]
I was wondering whether some nonprintable character (like ASCII BEL) gets mapped to a literal ?
, but at least the position is strange, and e.g. "Is a positve, negative, or zero?" (note the [IMHO inconsistent] extra spaces) in contrast is just as before (at least on the Python level, i.e., the string passed with the exception, before we strip "ECL says: Maxima asks: ").

for the record, maxima 5.26.0 cannot do similar definite integrals involving abs, either:
(%i2) integrate(abs(cos(x)),x,0,2*%pi); log: encountered log(0). [...] (%o2) 0

reported here.
comment:88 Changed 8 years ago by
There is a regression: maxima 5.29 (and 5.28) cannot compute integrate(sqrt(x + sqrt(x)), x)
. Reported as issue 2526 on Maxima's tracker. This leads to a doctest failure in maxima_lib.py
(line 716).
comment:89 Changed 8 years ago by
 Description modified (diff)
 Status changed from new to needs_review
remaining doctest issues are due to extra ?
characters appearing in Maxima library interactions in sage/calculus.py
, such as
Is a an ?integer?
and
Is a an ?even?\ ?number?
instead of
Is a an integer?
and
Is a an even number?
This needs to be investigated, IMHO.

Replying to dimpase:
the spkg is updated to work with ECL 11.1.1, as well as with the new ECL 12.12. Doctests show that the ?integer?
stuff does not go away if ECL 11.1.1 is used. So this is the new Maxima to blame for.
comment:92 followup: ↓ 93 Changed 8 years ago by
I'm doing git bisect
on the Maxima repo to try to find the places to blame. It looks it was a long story, more than just a single change to undo. The first bad commit after the clean situation, as if in 5.26.0, is
4e2e7fb738e6f9f1955a5378ae392a1930b30bce Merge branch 'sharecleanupbranch201110'
Maxima identifies itself as Maxima 5.26.0_70_g4e2e7fb_dirty
, and one gets
sage: var('a');assume(a>0);limit(x^a,x=0) a ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multiline string', (205, 187)) [...] RuntimeError: ECL says: THROW: The catch MACSYMAQUIT is undefined.
looking at the commit more carefully, one sees renaming to_poly_solver
to to_poly_solve
.
If I make this change in sage/interfaces/maxima_lib.py, line 142, the error go away. So in fact these ?integer?
things got in later.
Back to git bisect
now.
comment:93 in reply to: ↑ 92 Changed 8 years ago by
After some more
git bisect
, finally, it is here:
https://sourceforge.net/p/maxima/code/ci/f5e9b0f7eb122c4e48ea9df144dd57221e5ea0ca
to blame for ?integer?
It was meant to fix this, but Sage has it fixed already. I will post a patched spkg with this patch undone.

I like this! Only issue is that now #13860 has been merged in the meantime, so possibly this should be based on that? Clearly some of the changes are identical (like the image removal, asdf compatibility), since Dima made both of them! Unsure also on how JP's changes should be handled... But I'm very reluctant to put "needs work" for such things either.

#13860 and this ticket are independent of each other. Indeed there is small parallelism in changes, but that's all.

I just meant in terms of the HG repository for this spkg, which would seem to indicate that one should base the p0 and p1 here on the p1 there.

I don't understand. Indeed, 5.26.0.p1 and 5.29.1.p1 are separate branches. So what?

I think this is pure bullshit in this case, about single branch. Let's deal with bullshit when/if it comes to it. If we are quick enough 5.26.0.p1 won't even get merged in any (stable) release.

Fair enough, in which case I'll remove that dependency, which leif introduced. Anyway, I can't review some of the more technical changes in JP's package, but the Sage side seems okay.

Actually, he had fewer changes than I thought. The change in Dima's package to deal with various names for the library was already positively reviewed at #13860. So... lookin' good. Shall we say positive review? It's certainly been tested quite a bit.

a minor point: for the test in functional.py that (now) takes a long time, without the
long
option, the variable t
is not defined, and the test on
t.simplify_exp()
fails with:
NameError: name 't' is not defined
Probably the t.simplify_exp()
line should be commented with # long time
too.
Otherwise all doctests pass on top of Sage 5.5, thus I would give a positive review, but since this ticket is quite long, I'm not sure...

Well it works but I am not sure we should patch exp_integral.py this way. The old result was to demonstrate that something was broken. We should change the comment to reflect that is fixed or find another broken example. By comment I mean this bit:
Note that due to some problems with the way Maxima handles these expressions, definite integrals can sometimes give unexpected results (typically when using inexact endpoints) due to inconsistent branching::
That may be a bit pedantic however.

This ticket doesn't depend on #13324, as now both Maxima versions (5.26.0.p1 from #13860, and the 5.29.1.p1 from here) can cope with the new as well as the old ASDF naming scheme.
But the dependency is probably some artificial one for the release process, some I'm leaving it as is...

So all the changes in #13860 were completely pointless then?
When I worked on #13860 it was not clear that the current ticket can be done so fast.
The changes on #13860 are all basically repeated, in a slightly different way, on this ticket. Due to our scheme of working on packages it wasn't trivial to properly merge the changes, so I just copy/pasted from source.
