 Usually you cannot join a Google group without a gmail account, so you
 won't be able to join with the cs.berkeley.edu address. I could add
 you to the list of subscribers with that email address if you so
 desire.

I don't think that's true - I joined the group with my old email address.
I now have a gmail address, but prefer to use a mail redirecting address
as below which forwards to the gmail mailbox. I had no real problems
setting up the Google groups to use either address.

 Hello folks,

 Here goes 3.0.rc0. We knocked out a couple blocker, merged the new
 R pexpect interface. This release should also build out of the box
 on RHEL 5/Itanium and SLES 10/Itanium without the need to set any
 FORTRAN env variables. We have a new blocker (#2972), some doctest
 failures with the R doctests, but things are moving toward a stable
 3.0 release. We also merged a lot of Debian build fixes, so we should
 finally get close to the release. So please build, doctest and report
 and issues you come across. We closed a total of 254 tickets so far.

 Sources and binaries are in the usual place:

Sorry I've not been able to do any tests on the alphas - tied up with other
matters.

Surely ctrl+m = Enter ???
Maybe ctrl+J might work (Join)?   [ ctrl-J == line-feed == Unix newline ??]

  If that doesn't work, then I'll be really baffled (ok, even more baffled

  Ahah!  Now it works --- I can finally click on evaluate!  Thanks very
  much.
 
  The critical value seems to be somewhere around 150.  When I set the
  delay at 150 I found that sometimes cells failed to evaluate (and when
  it's a previously evaluated cell that you've edited, this can be hugely
  confusing), but most did. So I've set the delay at 250, and it's working
  well with both Firefox and Safari.

 Ok.  My gut reaction is, Javascript sucks, I hate it.  But on reflection,
 a design which requires such number-twiddling was probably not the best to
 begin with.  I think I have a better way to manage these links... I should
 have a patch up in a few, if my new idea works.

Sorry I took so long to test it out. Have upped the time to 250 and that
seems to have cured the problem on my machine (2.8GHz Toshiba Equium Laptop).

Not surprised that I hadn't figured out what was going on!

I wasn't sure which copy of js.py to modify, but hit the right one at the
second try. Used my web designers toolbar to display the Javascript to check
whether the change had been effective. I still haven't figured out the
Sage tree structure.. :-)

   The evaluate links for the notebook introduced in SAGE 2.9.2 have
   never worked for me (Mac OS X 10.4.11, SAGE 2.9.2 -- 2.10.2 + either

   correct, e.g., (reformatted):
 
  a href  = javascript:evaluate_cell(115,0)
 class = eval_button
 id= eval_button115
 alt   = Click here or press shift-return to evaluate
  evaluate
  /a
 
   but clicking on the link has no effect.  This is a pity, as it's a
   (potentially) very nice feature.  The cells evaluate perfectly well
   with shift-return.

 I just want to point out that the evaluate link *does* work for me
 and most people in Firefox.   It does not work for me in Safari.
 I don't understand why it doesn't work, but all your hints in this
 email will help.  Thanks!  We're tracking this issue at
  http://trac.sagemath.org/sage_trac/ticket/2332

   Looking at this link, and cell.py line 575, where it's created, I fail
   to see what is wrong.  Perhaps the javascript function evaluate_cell
   (defined in js.py) can't be found in this context?
 
   One thing I did notice is the attribute
  alt=Click here or press shift-return to evaluate
   There is no alt attribute for the A element in HTML 4.01, so it has no
   effect here.  Probably 'alt' should be replaced by 'title'.  Though,
   of course, this isn't the cause of my main problem.
 
 
   A couple of other details from cell.py noticed in passing:
 
   line  64: math_parse is defined in html.py not cell.py
 
   line 577: has no effect.  Presumably it should have been commented out
   along with lines 579--584.
Just to add that I've had some problems with evaluate links using Firefox
on Ubuntu 7.10. I've mentioned it before, but I've upgraded the OS and Firefox
(2.0.0.12) and it still is somewhat erratic. Clicking on the link works
most times, but every now and then it simply 'deselects' the current cell
but fails to notify the server. No vertical bar to suggest evaluating, and
the cursor disappears. Clicking on the cell restores sanity. I've monitored
the network traffic using wireshark (with the server in insecure mode so
I can read the messages) and see all the transactions up to the point where
I click on the link but nothing comes through at that point. Must be something
in the Javascript, I guess, but I haven't been able to figure out what as
yet.

 What happens when you try other web browsers, e.g,. opera?

Don't have any other browsers at present.

 I just tried and the evaluate button _does_ seem slightly flakie when
 I just tested
 in Safari, in that sometimes I have
 to click it more than once, and once I had to press shift enter
 instead.  But the whole
 state of the worksheet doesn't get messed up for me.

It doesn't mess it up - just leaves it without a cursor - i.e. no 
'current' cell. There's no bar to indicate processing in progress.
As soon as I click in a cell it's all back to normal.

Hoping to find some time tomorrow to try and track it down.

  which is included (javascript/js.main) but never get anything back.
  Using view
  page source only shows the link to it. I tracked down the source of
  this to
  find that it is generated 'on-the-fly' by server/js.py which makes it
  difficult to
  follow. Does it vary depending on context?

 If you install the web developer addon for firefox (go to
 https://addons.mozilla.org/en-US/firefox/addon/60 and click install),
 you can see the *generated* page source (i.e., what you are actually
 seeing, not just what was originally on the page).  Install the addon,
 restart Firefox, and note the additional toolbar.  Under the View
 Source option, select View Generated Source to see the actual source
 of what you are looking at, whether or not the source was generated on
 the fly or originally was there.

 The web developer toolbar is one of the best things Firefox has going
 for it for web developers.  Other things I've used it for were modifying
 the source or CSS styling of a page and seeing the page update in real
 time, examining the CSS structure of a page just by moving my mouse over
 elements, enabling or disabling features easily, changing the size of my
 browser to simulate smaller screen sizes, and lots of other things.

 The other firefox extension that might be useful here is Firebug,
 thought I think that at least some of firebug's functionality overlaps
 with web developer.

Thanks for that. It looks really useful. Took me while to find what I
wanted as there are so many facilities provided! All I have to do now is
to get the problem to reproduce!

[sage-devel] Possible bug in EllipticCurve(string)

2008-01-15 Thread bill purvis

I've just tried using the alternative method, using Cremona naming,
to create an elliptic curve:

E=EllipticCurve(5077a)
E.gens()

When I evaluate the second statement, it returns nothing.
This works fine using the vector of coefficients method.
Should I open a Trac ticket or am I doing something stupid?

 which browser and operating system do you use?

 Try to enable javascript debugging informations to catch possible
 errors the next time it happens. They would be very helpful.

Sorry, I should have included these:
Linux (Ubuntu 7.04)
Firefox (2.0.0.11)

I've just done a quick run though a worksheet, after about 4 evaluations
it did it again. I had the error console open and nothing new appeared.
I presume this includes javascript errors as there is no other obvious
way to get them (Mozilla used to have java console, javascript consoles
as far as I remember). I had clicked on 'All' to get errors and warnings.

 I can not replicate this. You might have been confused about whether
 or not you were actually logged in or something? Please give clear
 step-by-step directions that allow you to replicate tis problem every
 time.

 Thanks!
Sorry, William, two problems getting mixed up.

I had just logged in for the first time as 'bill' and before
creating any worksheet, clicked on 'Search worksheets'. Probably
a stupid thing to do as I had not yet created any. However, 
someone is bound to do this sooner or later and if it causes
the system to log out from sage it could put a newbie off.
Just thought I ought to report it.
Maybe it's a side effect of my round-the-houses method of creating
my user-id.

I'll try restarting the server with accounts=True and create a further
id by that method and see if I can reproduce it under those conditions...

 That is a bug. I just checked and the native-execute did get applied,
 but the sdist target doesn't seem to be aware of it. I will fix this
 in alpha3. As a workaround apply the patch from
http://trac.sagemath.org/sage_trac/attachment/ticket/975/native-execute.patch

Michael,
sorry, but I don't follow this. It says to apply to sage-scripts, but I
can't find a directory of that name in my source. Can you be a bit more
explicit? Having found where to apply it, do I just run 'make' again?

OK, managed to figure it out... I realised that the 'sage_scripts...' referred
to was a package, unpacked it then created a copy in there. I then realised 
that these scripts just get copied into .../local/bin by make, so I just
copied it across, did a 'chmod 755 native-execute', and re-tried.
That now seems to work - at least it has brought up a notebook in my
firefox window. Sorry about the extraneous stuff while I figured out 
what to do
