The size that is to be transferred, and the total repository size.

Yes it does - when displayed, one could make an informed choice.
But it doesn't show this, just the object count.. and that is of low
It so happened last week that I tried cloning a repository with a
seemingly moderate amount of objects and small code base. However, full
Java RE zips had been checked in and updated multiple times - suddenly
my monthly 3G traffic limit was exhausted. Needless to say without a
clue how much more data would follow, I aborted the transfer - and was
left with a net result of *zilch* bytes of code, and a line cut down to
ridiculous speed. Now I can't even sync up my Drupal copy.

Well, if it requires that, so be it. I fail to understand why this
wasn't considered before.

And that's true for all my repositories, since none of them was cloned

What about --shallow, --depth?

Many changes for the better are not trivial. And still worth it.

Ok - yet that probably doesn't invalidate all arguments in favor of it.

Thanks for the tip, I will forward it to the server administrators.
However, this does not help to handle the huge amount of commits to
fetch that pile up within a couple of months.

I wasn't even mentioning that, but that'd be nice to have aswell^^...

While downloading bundle delta files definitely is a plausible solution
- isn't that quite far from user friendly?

Kindly ask the author to locally rewrite his history and recreate the
repository with *LINKS* to JRE zips instead?
Not for a second did I doubt the efficiency of git's packing and
compression algorithms! That's why I'm quite amazed about the shear
existence of these issues of not showing the repository size before
downloading (or, IIUC, *anywhere*) and a protocol that is incapable of
resuming or partly fetching a repository, even though it obviously
provides means of negotiation between server and client.. Just boggles
me that within 7+ years of development this hasn't been addressed
(disclaimer: I do not claim to grok the protocol - not wanting to put
blame on anyone here :).
> Have you tried to shallow clone the repository in question?
No - would it allow me to fuse the two repositories afterwards? That'd
actually be quite cool and a good idea to instantly solve my current
problem... gonna try that, thx :)
