For 1.6 with laplace I have reported it upstream on giac's forum: https://xcas.univgrenoblealpes.fr/forum/viewtopic.php?f=3&t=2531
but for the sqrt(5) appearing in the doctests of giac.py I suspect some default configuration that is not dependent of the version of giac. Could it be that the user .xcasrc is taken into account?
Then I think it would be more natural to force the configuration to not use sqrt before the computation with:
sage: giac.with_sqrt(0);
NB: this function returns the previous value of this setting so in a doctest it is better to not print the answer)

downgrading giac makes those tests pass again, so there's definitely some change in 1.6 involved.
comment:5 Changed 2 months ago by
Yes, it's an improvement, done for geogebra. Forcing the sqrt mode of Xcas to false should fix sage regression test, as explained by Frederic. Laplace bug is fixed in my source tree, I will make a new release probably next week.

Incidentally, with giac 1.5.063 on manylinux2010standard
(from #30195), I get (https://github.com/kliem/sage/runs/908011984)
In file included from misc.cc:9275: misc.cc: In function 'std::string giac::fetch(const string&)': misc.cc:9289:28: error: 'CURLOPT_ACCEPT_ENCODING' was not declared in this scope curl_easy_setopt(curl, CURLOPT_ACCEPT_ENCODING, "deflate"); ^~~~~~~~~~~~~~~~~~~~~~~ misc.cc:9289:28: note: suggested alternative: 'CURLOPT_ENCODING'
It should be checked whether this goes away with the update
comment:8 Changed 2 months ago by
Yes, I do remember a problem with curl in an earlier giac. I believe it is fixed in 1.5.087+.
comment:9 Changed 6 weeks ago by
Should we continue waiting for another 1.6 patch release or upgrade to latest 1.5.x in the meantime?
comment:10 Changed 6 weeks ago by
I would be OK to move to 1.5.087 already.

You'll need https://github.com/cschwan/sageongentoo/blob/master/scimathematics/sage/files/giac1.5.0.87.patch for sage's doctests.
comment:15 Changed 6 weeks ago by
Updating doctests is probably better done together with #29541
comment:16 Changed 6 weeks ago by
By the way, it seems that we don't install giac correctly (before or after this update):
$ giac help // Maximum number of parallel threads 1 // Unable to find keyword file /Applications/usr/share/giac/doc/en/keywords Help file /Applications/usr/share/giac/doc/en/aide_cas not found Added 0 synonyms Help file /Applications/usr/share/giac/aide_cas not found :1: syntax error line 1 col 1 at  in help undef // dclock2 0.00015 // Time 0 // Total time 0

Before or after, this doctest makes no sense.
The _latex_
method is broken  it adds quotation marks
sage: g = giac('(x^4  y)/(y^23*x)') sage: g (x^4y)/(y^23*x) sage: s = g._sage_() sage: s (x^4  y)/(y^2  3*x) sage: latex(s) \frac{x^{4}  y}{y^{2}  3 \, x} sage: latex(g) "\frac{(x^{4}y)}{(y^{2}3\cdot x)}"
Is anyone using this interface at all?

I don't know :)  the pexpect interface and the optional giacpy_sage package are the only way to interact with giac right now. I cannot find anything linked with libgiac in sagelib. But the latex interface in particular? I don't know. The latex spat out for that doctest is different in the currently shipped giac, 1.5.063 and 1.5.087.

Needs review
comment:28 Changed 6 weeks ago by
there is a strange behavior in this version of giac (I have tested with 1.5.0.85, 1.5.0.87 and 1.6.0.7)that breaks giacpy_sage doctests. (cf your comment 25 in #29171) indeed the c++ _size function applied to the empty list seq[] doesn't return 0 as with giac 1.5.0.63 and earlier version but it returns some configuration setting.
Example: in icas len(seq[])
gives 0 with 1.5.0.63 but it now gives
[["atom","cplx","idnt","frac","vector","symb","strng","other","total"],[2,0,0,0,3,0,0,0,240]]
with 1.5.0.87
I have reported it there https://xcas.univgrenoblealpes.fr/forum/viewtopic.php?f=3&t=2534#p11776 to know if this modification will remain or is a bug to know if we patch giac or adapt giacpy.

OK, I guess we should hold off with this update.
comment:30 Changed 5 weeks ago by
So the answer was that it is a modification usefull for very low memory systems (calculators). Whether or not these extra lines will be put inside an #ifdef in later versions of giac is still in discussion. I guess we can let it as is

Moreover, for the keyword message, I have tried on linux with parisse's debian package. with LANG=C I have also the same (0 synonyms added) with LANG=en_US I have 26 synonyms added but all are GUI related (turtle mode). so I don't think that it is a problem. so this ticket looks good to me. tested on fedora fc30.x86_64 (make test was OK)

1.6.0 is out, causing a few test failures:
The ones in
interfaces/giac.py
just need the tests updated, thecalculus/calculus.py
failures are an upstream issue
