Hello list, my name is Renzo Carbonara and I'm new here in the git
neighborhood.


Now back to business, when using --pretty=format:some_format with git
rev-list, an additional non-requested line is printed before every
commit ("commit <sha1_id>"). Example:

git rev-list output (BAD):

k@k0001 ~/linux-2.6 $ git rev-list -2 --pretty=format:"%H: %cn" master
commit f4be31ec9690cfe6e94fcbed6ae60a6a38b3c3ed
f4be31ec9690cfe6e94fcbed6ae60a6a38b3c3ed: Linus Torvalds
commit 44cad261025c04327fd7e847a7088fd3031b0c3e
44cad261025c04327fd7e847a7088fd3031b0c3e: Linus Torvalds


git log output (GOOD):

k@k0001 ~/linux-2.6 $ git log -2 --pretty=format:"%H: %cn" master
f4be31ec9690cfe6e94fcbed6ae60a6a38b3c3ed: Linus Torvalds
44cad261025c04327fd7e847a7088fd3031b0c3e: Linus Torvalds



this was tested with versions:
 - 1.5.3.7
 - 4cdda2b895dfb6ba084e3952cbf4274a6a2e0338


Cheers,

Renzo Carbonara

Is this a bug? I've the same “problem” in my rebase with merge patch
series and added a “|grep -v ^commit”. But if this is a bug, I can remove
it.

Schöne Grüße, Jörg.

I personally do not think the above is a particularly desirable output,
but that's how rev-list worked for a long time and existing scripts
probably expect it that way.

rev-list is for script consumption, and giving --pretty=format that has %H
in it would be asking for redundant information.
