Usually running a test under "-v" makes it clear which command is failing. However, sometimes it can be useful to also see a complete trace of the shell commands being run in the test. You can do so without any support from the test suite by running "sh -x tXXXX-foo.sh". However, this produces quite a large bit of output, as we see a trace of the entire test suite. This patch instead introduces a "-x" option to the test scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this turns on "set -x" only for the tests themselves. This can still be a bit verbose, but should keep things to a more manageable level. You can even use "--verbose-only" to see the trace only for a specific test. The implementation is a little invasive. We turn on the "set -x" inside the "eval" of the test code. This lets the eval itself avoid being reported in the trace (which would be long, and redundant with the verbose listing we already showed). And then after the eval runs, we do some trickery with stderr to avoid showing the "set +x" to the user. We also show traces for test_cleanup functions (since they can impact the test outcome, too). However, we do avoid running the noop ":" cleanup (the default if the test does not use test_cleanup at all), as it creates unnecessary noise in the "set -x" output.

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 version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.
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 (read
Documentation/SubmittingPatches for instructions on patch submission).
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://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list. The discussion following them give a good reference for
project status, development direction and remaining tasks.
