Accessing the reflog remotely

Hi,

I guess the answer is "no", but I'll still ask in case ...

Is it possible to access the reflog of a remote repository other than
logging into this repository?

My use-case is the following: I want to checkout "the last revision
pushed in master on ssh://host/repo/ on day D at midnight" (to fetch
the project of my students ;-) ). If it were locally, I'd do

  git checkout 'origin/master@{Nov 3 00:00:00}'

But this tells me where _my_ local master was on that date (i.e. the
last revision I had pulled).


So, the best I can think of is:

ssh host 'cd /repo/ ; git tag final-version "master@{Nov 3 00:00:00}"'
git fetch --tags
git checkout tags/final-version

Is there a better way?

Thanks,

Matthieu Moy provò:

  git checkout 'origin/master@{Nov 3 00:00:00}'

But this tells me where _my_ local master was on that date (i.e. the
last revision I had pulled).

ssh host 'cd /repo/ ; git tag final-version "master@{Nov 3 00:00:00}"'
git fetch --tags
git checkout tags/final-version

At least you can avoid the tag:

git checkout `ssh host 'GIT_DIR=/repo/ git rev-parse "master@{Nov 3 00:00:00}"'`

Buongiorno.
Complimenti per l'ottima scelta.

Keep in mind that bare repos don't have reflogs by default, so unless  
you enabled the reflog manually there is none.

You could checkout the first revision which committer's date is older 
than midnight.  Of course that means you have to trust that students 
didn't mess up with time stamps.

I think your best bet here would be to either run a cronjob at the
target time that tags all submissions, or to deny pushes after the
target time with a pre-push hook.

This won't solve your problem but I'll mention it anyway as it may be
related.

A distribution point repository like this is often bare, and reflogs are
not enabled in bare repositories (primarily due to my stupidity^Wbeing
overly cautious---I was very skeptical about reflogs when we introduced
it).  It may make sense to enable reflogs everywhere by default in some
major version bump.

Also a distribution point repository is often served by gitweb and it
would be really nice if there were an option to allow its summary view
to show commits annotated with reflog entries, e.g.
