git hook error

git hook error

[Ricardo Wurmus]

Since a few days I see this when pushing to the repository:

--8<---------------cut here---------------start------------->8---

remote:     import git_multimail        
remote: ImportError: No module named git_multimail

Is this our fault or did something change on Savannah’s side?

Thanks for the pointers!

So… uhm, what do you all think about hosting our Git repos by ourselves?
Ideally *not* on the servers of the build farm, but on other hardware?

I would ask, why would we want to do that?

The motivation for that is not found in just one big problem.  It’s a
small trickle of minor annoyances:

- Savannah’s uptime isn’t quite as high as we’d like
- we can’t have server-side checks to prevent pushing bad commits
- we can’t have server-side hooks to better integrate with the build farm
- we can’t have per-branch rules (e.g. to allow contributors to push to
  some but not all branches)

Hi Ricardo,

I wonder if Savannah monitors and publishes numbers, and how they 
compare to other popular forges.

Why should we do better?  We haven't even managed to set up a git 
mirror after all these years.

Why not?  Which of these can't be got with server-side hooks?  How 
would you get them on Guix infra then?  Could the Savannah admins 
accommodate us further, if needed?

If the real reason for even one of them is ‘well, we can, but 
nobody wants to write those hooks’, that only bolsters my previous 
scepticism.

Kind regards,

Maybe not self-hosting, but I would really appreciate a move to a
better forge, like Sourcehut. I have... very few positive
things to say about Savannah's UI, at least from a casual user
perspective. I don't know what it's like for contributors.

Okay. I wonder if we could actually do a better job, or if anybody who
hosts a comparable repo does.

Our own record with the build farm and the record of major hosts like
Github are both somewhat discouraging. And if we could only hope for an
equivalent uptime to Savannah, it doesn't seem worth it to shoulder this
work ourselves.

We do actually have a server-side hook in place to prevent pushing
unsigned commits. And if we wanted to add more tooling, the Savannah
admin(s) would help us.

Now, if we just wanted more control and visibility into the
infrastructure, that's a reason, but again, I wonder if it's worth the
effort. In terms of infrastructure maintenance, we already seem to be
stretched thin.

My opinion is that, in order to consider hosting our own Git server, we
should wait until people are using declarative Guix configuration to
operate reliable, performant, and public Git servers that would meet our
needs. That is, the Guix project needs to grow this capability without
the heroic effort of a single volunteer. Because that's what we have now
with Savannah, more or less, and we don't have to work for it. Maybe
this has already been achieved, I don't know.

I asked; they don't.

Well, I agree with Ricardo that the list of minor annoyances is greater
than the burden of maintenance.  I also agree that it is again another
load on “our” shoulders, but somehow at this point, is it that much
compared to the gain?

Hum, maybe I miss something but changing the Git server is transparent
for the users.  One commit pushed to Savannah changing the URL, the user
runs “guix pull”, then the next “guix pull” will pull the new location.

However, it is not clear what happens for “guix time-machine”?

Well, as it is possible to list several substitutes servers, maybe the
first step could to add another Git server in addition to Savannah,
mirror this Git server using Savannah, then flip and mirror Savannah
against this Git server.

Last, this server should be part of a CDN, IMHO.
