Hello,

Just wanted to update my local repo of Worg:

--8<---------------cut here---------------start------------->8---
[sva@MEDIACENTER] ~/src/Worg>git pull
error: Unable to find 9a6e35ee0276b7736f5a08dccba52a4374574892 under http://repo.or.cz/r/Worg.git
Cannot obtain needed blob 9a6e35ee0276b7736f5a08dccba52a4374574892
while processing commit f58d7c210e22c66d18dae80f45280e32c086b7c3.
error: Fetch failed.
--8<---------------cut here---------------end--------------->8---

Does that tell you something?

Best regards,
  Seb

Does this problem still occur and what remote repository are you
pulling from?  (cat .git/config) There are postings on the web that
mention this error when pulling via http: protocol.

Pulling git+ssh://repo.or.cz/srv/git/Worg.git works fine here.

Best,

- Does using ssh give you compression for free?  Hence, a quicker way to
  download big repos?

- Can you use whatever protocol (git, http, git+ssh) in front of any "git
  URL"?  I mean, if I see on the Web, http://xxx.git, can I replace http by
  git with no impact?

Best regards,
  Seb

Git can interact with the remote repository differently, allowing it
to do some de-duplication over SSH that it can't do over HTTP. Also,
depending on your SSH configurations SSH can (and generally is, I
think, correct me if I'm wrong) somewhat compressed (But then, so is
HTTP with DEFLATE/gzip sometimes). This might not speed up the
operation both because of the processor overhead to do the
compression, but also because SSH's encryption takes a bit of
overhead. 

Basically, "it depends on what free is," and pragmatically git pull's
over SSH are quicker than git pulls over HTTP.

No. SSH (and git) protocols specify the path of the file based on
where the file lives on the host machines file system. Start at the
root / (or chroot) in the top level and go from there. The paths for
HTTP are dependent upon the configuration of the web server and are
often somewhat distinct from what is actually going on in the file
system given virtual hosting and URL rewriting. 

Hope this helps. 

Cheers,
tycho

It still does, today[1], after having worked a couple of times.

To do this, I need a password on repo.or.cz. Who do I have to ask for this?

Best regards,
  Seb

Just register a user at [1] with a SSH public key.  IIRC the user name
in the key comment must be the email adress.

E.g.

ssh-keygen -C "you@somewhere.tld"

Or instead of git+ssh you can use the native Git protocol: 

git://repo.or.cz/org-mode
