git source mirrors inactive

git source mirrors inactive

[Andreas Röhler]

Hi folks,

seems Emacs git mirrors like

http://git.savannah.gnu.org/gitweb/?p=emacs.git;a=summary

and

http://repo.or.cz/w/emacs.git

are no longer up-to-date, as it's used to be for a long time.

Might that be due to the fact, it's maintainers have been discouraged 
rather than being appreciated for it?


Please take my regrets, as

http://repo.or.cz/w/emacs.git for example

has been felt 5-10 times faster than

bzr://bzr.savannah.gnu.org

That's a serious set-back.

Regards,

Andreas

The mirrors on github and gitorious seem to get regular updates, so you
may want to use one of those (see
http://www.emacswiki.org/emacs/EmacsFromGit).

https://github.com/emacsmirror/emacs.git

looks good, while

http://gitorious.org/emacsmirror/emacs

says

"Mirror of git://repo.or.cz/emacs.git (webinterface: 
http://repo.or.cz/w/emacs.git) which in turn mirrors the official"

ie the latter wouldn't help.

Thanks,

Andreas

This Git mirror business is sad, indeed.
Could some people (plural, ideally) volunteer to maintain the
git.sv.gnu.org mirror up to date?  That would be very appreciated.

If someone can give me information on how and the power to do so, I'd
happily keep it up to date.

Hi,

AFAIS Emacs is going to lose two mirrors maintained by people with 
excellent skills in the area and beside.

Im afraid two hands are enough when counting active developers of this 
quality. When counting people with related git-skills at the dispose of 
Emacs, one hand will be sufficient.

Maybe it's worth to re-consider policy with this respect.

Cheers,

Andreas

Thanks, below still an example pointing at the convenience of working 
from git:

It is meaningless to pick up a random command and compare based on
that command alone.  Here's another meaningless comparison:

  eliz@fencepost:~/bzr/emacs/trunk$ time bzr annotate src/xdisp.c > /dev/null
  real    1m43.832s
  user    1m25.740s
  sys     0m3.110s
  eliz@fencepost:~/git/emacs$ time git annotate src/xdisp.c > /dev/null
  real    5m9.646s
  user    4m18.400s
  sys     0m3.580s

I don't know how frequently you need to know the last 2 changes of
python.el, but the number of times I needed to annotate xdisp.c during
the last 2 years is about twice a week.  I will gladly trade a 29-sec
wait for 3.5 min wait.  YMMV.

Interesting, thanks.

BTW found a text discussing that as special slowness in git, with some 
recommendation to work around

http://ondioline.org/mail/bitkeeper-and-the-genesis-of-git

As for the daily work indeed I have a look quite often at the last commits.

Me too, but not normally for specific files.  Just "bzr log -l N" is
much faster, because it doesn't need to dig into the history looking
for a specific file.

I see nobody else replied, so here is what I know:
- I'm not sure about the current permissions on the emacs.git tree.
  If all is well there, all you need to be added as member of the
  `emacs' savannah project and that will give you write access.
  But IIRC there were some problems around this in the past.
- I'm not sure either how the conversion from Bzr to Git is done.
  IIUC it uses the fast-export/fast-import thingy, but other than that,
  I do not what is involved.
Could someone help?  Andreas?

Personally, I use git-bzr-ng¹ and it works well for such a thing, and
is pretty straightforward to use.

Stefane, the git mirror on savannah has not updated since Apr 1
