"git cmd :/no-such-string-ever-existed" runs an extra round of get_sha1() since 009fee4 (Detailed diagnosis when parsing an object name fails., 2009-12-07). Once without error diagnosis to see there is no commit with such a string in the log message (hence "it cannot be a ref"), and after seeing that :/no-such-string-ever-existed is not a filename (hence "it cannot be a path, either"), another time to give "better diagnosis". The thing is, the second time it runs, we already know that traversing the history all the way down to the root will _not_ find any matching commit. Rename misguided "gently" parameter, which is turned off _only_ when the "detailed diagnosis" codepath knows that it cannot be a ref and making the call only for the caller to die with a message. Flip its meaning (and adjust the callers) and call it "only_to_die", which is not a great name, but it describes far more clearly what the codepaths that switches their behaviour based on this variable do. On my box, the command spends ~1.8 seconds without the patch to make the report; with the patch it spends ~1.12 seconds. Signed-off-by: Junio C Hamano <gitster@pobox.com>

GIT - the stupid content tracker
////////////////////////////////////////////////////////////////
"git" can mean anything, depending on your mood.
- random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
- "global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.
The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
