trac.sagemath.org unreachable

[Emmanuel Charpentier]

This morning (Aug 31, 2022, 8:43), any attempt to reach `trac.sagemath.org` ends up displayong a Python trace :

```

Probably unrelated because I was able to access the web page after the update but right now I get from the browser (chrome and firefox):

This seems a different problem. The website is not accessible.

The Web site is still unreachable.

Of note : I could create a new ticket (the one I was trying to fetch) yesterday afternoon. This might be a problem distinct from the one due to the key change (this week-end, IIUIC).

Perhaps need to update trac server ssh keys stored in github?

This is quite likely. Who has access, where is this done?

Do you mean 

  - you plan to roll back, or

  - suggest that someone else rolls back ?

In either case, as of 11:23 CET, still no access from a different machine (SSH key not yet updated)..

It is a day to think about how precious our trac is. Just be careful when you touch its soft database.  

[Dima Pasechnik]

no, it's the day to finally pull our **** together and decide to move
to a platform which is not held together by mud, python2.7, sticks,
and chewing gum,
a platform noone here knows how it works.

Trac is back. 

Anything lost?

Trac is a timesink.
Time spent on looking for fixes for it is time lost, that's for sure.

The trac project seems not well maintained, according to its website. 

We may need to plan migration while trac is still breathing...

this is only 10% of the probem - the real one is that we are many
versions behind its current 1.4, with various custom
hacks nobody knows about any more. And an attempt to update did not
seem to work.

By the way, I'm currently looking at a way to import trac wiki,
something we use quite a bit, into GitHub.

Or into gitlab, which we can host ourselves,

Whether we upgrade trac or migrate to other platform, the process should be gradual so  that we run an experimental new server along with the present trac server, sharing the (copied) database, for some (or long) time.

If we upgrade trac, the process could be 1.1 -> 1.2 -> 1.3 -> 1.4.

 

[Jan Groenewald]

Hi

The current version is 1.1.6. the packaged version for the new server is 1,.2, It seems even numbers are stable but the next and latest packaged version on debian/ubuntu is 1.5.3; 1.5+ is python3.

Trac upgrade guide is 1.0 -> 1.2 -> 1.4

https://trac.edgewall.org/wiki/TracUpgrade

Maybe the OS package upgrades support 1.2 -> 1.5.3.

I am going to look at 1.1.6 -> 1.2 packaged version on a trac-test copy of the VM but I must say the gitolite error put me off a bit, even if it is just disabling sshkeys.py for a bit. Then Frederic found other problems in ticket_branch.py/pygit2.

Regards,

Jan
