The example I initially added to "Skipping tests" wasn't very
good. We'd rather skip tests using the three-arg prereq form to the
test_* functions, not bail out with a skip message.
Change the documentation to reflect that, but retain the bailout
example under a disclaimer which explains that it's probably not a
good idea to use it.

Probably belongs in a separate patch. More importantly, it is missing
&&-chaining (not a regression, but it is best to set a good example).

Change the smoke testing portion of t/Makefile not to include
GIT-BUILD-OPTIONS. It's a shellscript, not a Makefile snippet, so it
had the nasty side-effect of sneaking e.g. SHELL_PATH = '/bin/sh'
(with quotes) everywhere.
Just add our own PERL_PATH variable as a workaround. The t/Makefile
already has e.g. an equivalent SHELL_PATH and TAR option which
duplicate the definitions in GIT-BUILD-OPTIONS.

Add the capability to send smoke reports from the Git test suite.
Currently we only notice bugs in the test suite when it's run
manually. Bugs in Git that only occur on obscure platforms or setups
that the core developers aren't using can thus go unnoticed.
This series aims to change that. With it, anyone that's interested in
avoiding bitrot in Git can volunteer to run a smoke tester. A smoke
tester periodically compiles the latest version of Git, runs the test
suite, and submits a report to a central server indicating how the
test run went.
A smoke tester might run something like this in cron:
#!/bin/sh
cd ~/g/git
git fetch
for branch in maint master next pu; do
git checkout origin/$i &&
make clean all &&
cd t &&
make smoke_report
done
The smoker might want to compile git with non-default flags, include
bisecting functionality or run the tests under valgrind. Doing that is
outside the scope of this patch, this just adds a report submission
mechanism. But including a canonical smoke runner is something we'll
want to include eventually.
What this does now is add smoke and smoke_report targets to t/Makefile
(this example only uses a few tests for demonstration):
$ make clean smoke
rm -f -r 'trash directory'.* test-results
rm -f t????/cvsroot/CVSROOT/?*
rm -f -r valgrind/bin
rm -f .prove
perl ./harness --git-version="1.7.2.1.173.gc9b40" \

The support for multiple test prerequisites added by me in "test-lib:
Add support for multiple test prerequisites" was broken.
The for iterated over each prerequisite and returned true/false within
a case statement, but since it missed a return statement only the last
prerequisite in the list of prerequisites was ever considered, the
rest were ignored.
Fix that by changing the test_have_prereq code to something less
clever that keeps a count of the total prereqs and the ones we have
and compares the count at the end.
This comes with the added advantage that it's easy to list the missing
prerequisites in the test output, implement that while I'm at it.

Some tests depend on not being able to write to files after chmod

Change test-lib.sh to test if this works, and if so it sets a new

when run under root.
There was already a test for this in t3600-rm.sh, added by Junio C
Hamano in 2283645 in 2006. That check now uses the new SANITY
prerequisite.

Change the test output to print needed prerequisites as part of the

skipped. Before:
ok 7 # skip <message>
ok 9 # skip <message>
After:
ok 7 # skip <message> (prereqs: DONTHAVEIT)
ok 9 # skip <message> (prereqs: HAVEIT,DONTHAVEIT)

TAP harnesses don't need to read test-results/*, since they keep track
of the number of passing/failing tests internally. Skip the generation
of these files when HARNESS_ACTIVE is set.
It's now possible to run the Git test suite without writing anything
to the t/ directory at all if you use a TAP harness and the --root
switch:
cd t
sudo mount -t tmpfs none /tmp/memory -o size=300m
prove -j9 ./t[0-9]*.sh :: --root=/tmp/memory
The I/O that the ~500 test-results/* files contributed was very

There are two ways a user might want to use "diff --relative":
1. For a file in a directory, like "subdir/file", the user
can use "--relative=subdir/" to strip the directory.
2. To strip part of a filename, like "foo-10", they can
use "--relative=foo-".
We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".
We can do what the user means here and strip the extra "/" (and only a
slash). We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

The dcommit command fails if an otherwise unmodified file has

Cannot dcommit with a dirty index. Commit your changes

This happens because "git diff-index" reports a difference

The fix is to run "git update-index --refresh" before
"git diff-index" as is done in git-rebase and
git-rebase--interactive before "git diff-files".
This changes dcommit to display a list of modified files before
exiting.
Also add a similar test case for "git svn rebase".

One test case checked the stdout and stderr of 'git add' by constructing a

is different from what the test case expected. Hence, check the two output

On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences. This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences. In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail. Neither is desirable.
So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.
Also, add a test to test for this breakage.

The '!()' notation is interpreted as a pattern-list on Ksh. The Ksh man
page describe it as follows:
!(pattern-list)
Matches anything except one of the given patterns.
Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list. If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.
