bug#41409: “guix pull” should show a progress bar for channel updates

[Ricardo Wurmus]

When I run “guix pull” (or “guix time-machine”) I see this message

   Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...

followed by disconcerting silence.  I can’t tell if it’s doing
something, nor can I see what the progress is.

Would be nice to have a progress bar or at least a spinner.

Most of the time is fetching from network so if you have a good
network connection, this step is not long enough to be disconcerting.
:-)

In addition to this whislist, it appears to me the same for "Computing
Guix derivation", even there is something moving.


All the best,
simon

It can take several seconds or even over a few minutes when fetching
from multiple channels.  For what it’s worth I got annoyed waiting for
“guix pull” on ci.guix.gnu.org, which has a pretty decent network
connection (even though users on the outside cannot see it this way due
to the firewall).

Wow! Few minutes.  To me, each channel (Gitlab, GitHub, etc.)  takes a
couple of seconds -- even with a poor Wifi connection -- and the
longest is Guix from Savannah: and "slow" as everything under gnu.org.
I feel much more frustrated by "Computing Guix derivation" which takes
ages on my machine and I never know if the computations are at 20% or
80% or whatever.
And I never pull on my laptop the current HEAD of master otherwise I
am waiting between 10 and 30 minutes building all the derivations
because they are not substituable yet; well I pull 1 or 2 weeks
behind.

Well, a spinner for the Git updating part could improve use cases:
first pull, long period between 2 pulls, firewall, etc..
On the other hand, an European mirror of guix.git could help too, IMHO.

Cheers,
simon

For the record, the main missing piece is in Guile-Git, which does not
yet provide bindings to the progress-report thingie for fetch
operations.

I’ve added support for the ‘transfer-progress’ callback in Guile-Git:

  https://gitlab.com/guile-git/guile-git/-/commit/7a3d97a72e7907213241f62d3bac926361f50f95

However, there’s an (unrelated) issue with libgit2 meaning that
Guile-Git is not in a releasable state yet:

And now the Guix side of it:

It’s a libgit2 bug but not a showstopper after all.
