[sage-support] Re: Excessive snapshots
Hi Michael,
No - didn't rebuild. Guess I figured it was some sort of
configuration file that got read at start-up. :-( At least now I
know which version to edit.
I don't think this explains why it was saving twice a minute
originally, when I'd built from source. user_conf.py must have been
read then. I'll run some experiments tomorrow and report here.
Are others on some version of 3.4.rc0 seeing snapshots (and .sage/
sage_notebook/backups/nb.sobj updates) at 3-minute intervals? Or
something different?
Thanks for the help.

Did you run "sage -b" after editing the file?
Sage 3.3 or later should not keep any snapshots around if the
worksheet is unchanged. If it does in your case there is a new bug in
there somewhere.

[sage-support] Re: Excessive snapshots
My 30 MB nb.sobj was also being saved twice a minute. Is this a
reasonable size for this file?
After some head-scratching, I found the thread
http://tinyurl.com/aht325
which had the following commands to use at the sage command line:
sage: nb = load('/home/rob/.sage/sage_notebook/
nb.sobj',compress=False)
sage: nb.conf()['save_interval']=int
(3600)
sage: nb.save()
This seems to have halted the high frequency of the saves, but I
haven't waited an hour to see if that is what will really happen.
It still does not appear that that the setting in user_conf.py was
having any effect for me.

Marshall, Thanks for the reply. I'm using 3.4.rc0, built from the source.

[sage-support] Division error in Sage 3.3 but not in Sage 3.1.1
Hi guys, I recently upgrade sage from 3.2.3 to 3.3. I'm also have sage 3.1.1 The thing is that the following commands give different results: F.=FiniteField(9) A. = PolynomialRing(F) K. = FractionField(A) f= 2/(t^2+2*t); g =t^9/(t^18 + t^10 + t^2);f+g In 3.1.1 gives the right answer (I guess) but in 3.2.3 give an error: ZeroDivisionError Traceback (most recent call last) ... ZeroDivisionError: division by zero in finite field. I don't know how those commands work in 3.2.3. I had a problem with sage 3.2.3, but Craig Citro helped me. Sage 3.2.3 couldn't open objects created in sage 3.1.1. This objects contain polynomials p(T) in F_q(t)[T]. Perhaps these problems are related. Any idea of how to fix that? --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Re: Excessive snapshots
Yes, running 3.3 should fix that. You can safely delete most of those snapshots if you want to save some space. Also, you can edit user_conf.py (in sage/server/notebook) to change the autosave_interval to something bigger (this is #5371 that you referred to, although there we are only thinking of upping it a little, you might want to only save once an hour or longer). -M.

This is because .set_hook() pushes your function onto a list of
handlers; the first handler in the list that does not raise a TryNext
exception is used. So you keep adding more and more copies of
repr_and_parent and repr_only onto the list.
Here's a variant that works for me (in limited testing).
import IPython
from IPython import ipapi
from IPython.genutils import Term
from pprint import PrettyPrinter
pformat = PrettyPrinter().pformat
_show_parent_mode = False
def _maybe_show_parent(self, arg):
if _show_parent_mode and hasattr(arg, 'parent'):
try:
print >>Term.cout, "%s\n\nParent: %s"%(repr(arg),repr
(arg.parent()))
return
except:
pass
raise ipapi.TryNext
ipapi.get().set_hook("result_display", _maybe_show_parent)
def show_parent():
global _show_parent_mode
_show_parent_mode = True
def hide_parent():
global _show_parent_mode
_show_parent_mode = False

[sage-support] Turning display of parents on and off
Thanks to the help of Robert Bradshaw, and to the file IPython/
hooks.py, I've cobbled together the following sage.init file:
import IPython
from IPython import ipapi
from IPython.genutils import Term
from pprint import PrettyPrinter
pformat = PrettyPrinter().pformat
def repr_and_parent(self, arg):
if hasattr(arg, 'parent'):
try:
print >>Term.cout, "%s\n\nParent: %s"%(repr(arg),repr
(arg.parent()))
return
except:
pass
raise ipapi.TryNext
def repr_only(self,arg):
if self.rc.pprint:
out = pformat(arg)
if '\n' in out:
Term.cout.write('\n')
print >>Term.cout, out
else:
print >>Term.cout, repr(arg)
return None
def show_parent():
ipapi.get().set_hook("result_display", repr_and_parent)
def hide_parent():
ipapi.get().set_hook("result_display", repr_only)
However, it doesn't work. In console mode show_parent() should turn
the display of parents on, and hide_parent() should turn it off. It
seems to work once - but not again. That is, parent display can be
turned on, and then off, but not on again - show_parent() has no
effect after one "cycle". I'm not quite sure what's going on - my
python knowledge is limited. And sometimes when parent display is on,
hide_parent() has no effect.
Any ideas?
Thanks,
Alasdair

We may be able to at least automate them for Sage, which would be a step forward. That said -- I'm really looking forward to Sage switching to Maxima + ECL.

Unfortunately the Common Lisp spec, while it recognizes the existence of character encoding issues, doesn't specify what to do when a byte can't be decoded to a character. Other Lisp implementations probably have their own ways to handle it.

Hi there, I suppose it has to be with permissions. Sage is installed at my home directory. If a run sage as a root (su and then ./sage) maxima works!!! But if only run sage with sudo ./sage it does'nt.

You have to follow the advice given in the output: run Sage on example1.sage, and then run LaTeX again. The file example1.sage is generated when you run LaTeX on example1.tex. When you do "sage example1.sage", that will generate yet another file, example1.sout, which LaTeX will use if you compile your document again.

[sage-support] sagetex issues
Hello
I have downloaded and installed the sage (os x 10.5 intel version).
Sage seems to be working fine. Then I downloaded sagetex 2.0
package. I moved sagetex.sty into user/library/texmf/tex/latex
folder. Then I moved sagetex.py into the sage folder.
Then I ran a simple latex code (copied from the example in the sagetex
folder.) using TeXshop. The following is the code.
%!TEX TS-program = sage
\documentclass{article}
\usepackage{sagetex}
\begin{document}
This is an example $2+2=\sage{2+2}$. If you raise the current year mod
$100$ ($\sage{mod(\the\year, 100)}$) to the power of the current day
($\the\day$), you get $\sage{Integer(mod(\the\year, 100))^\the\day}$.
Also, $\the\year$ modulo $42$ is $\sage{\the\year \percent 42}$.
\end{document}
It did not worked. I am getting the following in the console.

LaTeX Warning: Reference `...@sageinline0' on page 1 undefined on input

LaTeX Warning: Reference `...@sageinline1' on page 1 undefined on input

Run Sage on example1.sage, and then run LaTeX on example1.tex again.

pdftex.map}]

What seems to be the problem? Can someone help? Thank you very much.
Sony..
