Trying to delete some old worksheets, this happened:

Well, there already seems to be a notebook running on port 8000, so could that have something to do with that? Can you check and report back?

Do we support more than one notebook running from the same Sage instance?

Cheers,

No, this is not the case. No notebook on port 8000.

I don't think so. I would love to have the possibility to run more notebooks from different versions of sage!

Neither tom nor I can replicate this.

Could you try with a fresh NOTEBOOK directory? E.g.,

sage: notebook(directory = 'foo')

Let me tell what I did a few minutes ago.

I created a worksheet 'test' with sage-2.11, saved it and quit.

Started the notebook under sage-3.0.alpha5, selected 'test' and clicked on delete.

With the error mentioned above :(

Worksheets created with earlier versions and with alpha5 don't give this error!

[Jaap Spies]

Follow up: selecting an old ws and clicking on 'Archive' cased the same error here.

[Jaap Spies]

I reproduced this failure on a different machine Fedora 8, 32 bits with a ws made under sage-2.11. using Firefox-2.0.0.13.

Narrowing(?) this down: I get the same failure under sage-2.11 :(

Starting the notebook and selecting nothing(!) clicking on Archive or Delete gives the internal server error. Both on Fedora 7 and 8.

Even with sage-2.10.4, just clicking in the overview on Delete:

So I'm flabbergasted

This issue seems to be introduced with sage-2.10.1.

In sage-2.9 clicking on the Archive button gives a warning.

I put up some screen shots here: ​http://sage.math.washington.edu/home/jsp/screenshots/s1/

Could this have something to do with encoding? Jaap: what is the locale you use?

Don't think so. My Fedora install is just English (American). I do not use any localization.

Can anybody but Jaap replicate this problem?

[Jaap Spies]

How about this:

Something strange was going on with the notebook(), but
after hg_sage.pull() and ./sage -br the notebook
starts in Firefox with still the problem I have reported in trac #2935.

But when I start firefox by hand:  https://localhost:8001/
everything seems to work!

Jaap

[Jaap Spies]

Once again this is what I do now to avoid the error:

Start the notebook in sage-3.0.

Close the notebook tab in firefox.

Connect to ​https://localhost:8001/

Now I have a notebook running in which I can Archive en Delete worksheets.

Since nobody else can replicate this, and it could just be some weird cookie corruption on Jaap's computer (or a weird firefox bug), I'm closing this as invalid.
