[sage-devel] Re: no trac email notification

[ancienthart]

Will trac bugs posted in the last few days send out emails now, or do we 
need to update the trac ticket?

It says it failed to configure patch, which is truly bizarre. My first
guess is that you have a corrupted download. Try checking the md5sum,
and if it's correct, send the entire build log (or post it online
somewhere).

[sage-devel] Sage-5.0-beta5 build failed on linux

[Jonathan Hanke]

Hi,

I am trying to build the latest development version of SAGE on a large
multiprocessor dell linux machine, and it failed with the following error
message.  The error message is rather cryptic, so please let me know if
there is any specific architecture/log information you need.  Thanks,

Unrelated to #6028, but maybe we should leave some ticket open to change
top/prstat to a system call as David suggests.

Re: [sage-devel] Building a deb for sage on Debian/Ubuntu

[P Purkayastha]

I am not sure how your packaging works. Do you install into some temporary 
directory first and then tar/bzip the resulting directory? Then, if the 
user changes the directory in which (s)he installs Sage (and this will 
obviously happen), then it will need to be run as root once.

Also see this ticket which might be relevant for you if you are using the 
"make install" command: http://trac.sagemath.org/sage_trac/ticket/12347

If there were a solid proposal then *definitely* yes!   And the same goes
for any other component of Sage.

[sage-devel] Re: serious bug in sum

[rjf]

maxima 5.25.1, at least for me, gets the right answer


load(simplify_sum);
simplify_sum(sum (binomial(n,k)*k^2, k, 2, n));

returns


((n^2+n)*2^n-4*n)/4


This raises an interesting point.  If Sage were to get
GSOC approval to be a mentoring organization, would it
match mentors and students to fix bugs in Maxima?

Re: [sage-devel] Building a deb for sage on Debian/Ubuntu

When one does that, will it create new files? This is important

It would be really helpful, if, for example, the spreadsheet [1]
contains a column for notes. If a entry there results in a trac
ticket, then this could be noted there and if the problem is already
solved then also.

Is it (for someone) possible to edit [1] manually? If yes, can the
following be added:

12/13/2010 19:55:46 ValueError for w/h below 32768 occurs for 331:

[sage-devel] bugs from "the public bug reports from the notebook interface"

[Daniel Krenn]

In 2010 I reported some bugs via the public bug reports from the
notebook interface. I rewrite them to a trac-ticket now, since it seem
that this hasn't been done. Is there a way to add a note on [1], that
the corresponding line has lead to a trac-ticket (or is already fixed
or something)?

In general, what is done with the bugs reported there?

I checked that already. Didn't happen.

But since yesterday the problem is solved. I contacted my provider and
they found a bug in their configuration (which was changed on
10.2.2012). Now everything works fine, again.

Re: [sage-devel] Don't "import site" in sympy's installer (#12563) needs review

Re: [sage-devel] Build of GMP-ECM fails for sage 4.8 (on a buildbot node)

This machine is *not* part of the buildbot.  I'd be happy to add it
though, if the sysadmin wants to give me access.

This error is http://trac.sagemath.org/sage_trac/ticket/12501

[sage-devel] sage-5.0.beta5, ARM and ptestlong

[Julien Puydt]

Hi,

there are still a few failing tests.

Of course, there are the various gamma-related numerical problems, but
there is hope : http://trac.sagemath.org/sage_trac/ticket/12449

The vertex separation bug is still there even though a fix is almost
ready: http://trac.sagemath.org/sage_trac/ticket/12371

And finally, there's a problem with maxima I started to look into :
http://trac.sagemath.org/sage_trac/ticket/12586

I hope that helps,

Snark on #sagemath
