test-lib: consolidate naming of test-results paths
There are two places where we strip off any leading path components
and the '.sh' suffix from the test script's pathname, and there are
four places where we construct the name of the 't/test-results'
directory or the name of various test-specific files in there. The
last patch in this series will add even more.
Factor these out into helper variables to avoid repeating ourselves.

test-lib: parse command line options earlier
'test-lib.sh' looks for the presence of certain options like '--tee'
and '--verbose-log', so it can execute the test script again to save
its standard output and error. It looks for '--valgrind' as well, to
set up some Valgrind-specific stuff. These all happen before the
actual option parsing loop, and the conditions looking for these
options look a bit odd, too. They are not completely correct, either,
because in a bogus invocation like './t1234-foo.sh -r --tee' they
recognize '--tee', although it should be handled as the required
argument of the '-r' option. This patch series will add two more
options to look out for early, and, in addition, will have to extract
these options' stuck arguments (i.e. '--opt=arg') as well.
So let's move the option parsing loop and the couple of related
conditions following it earlier in 'test-lib.sh', before the place
where the test script is executed again for '--tee' and its friends.

'test-lib.sh' looks for the presence of certain options like '--tee'

command line options the test was invoked with.
The next patch is about to move the option parsing loop earlier in

effecively destroying "$@" by the end of the option parsing. Not
good.
As a preparatory step, turn that option parsing loop into a 'for opt
in "$@"' loop to preserve "$@" intact while iterating over the
options, and taking extra care to handle the '-r' option's required

test-lib: translate SIGTERM and SIGHUP to an exit
Right now if a test script receives SIGTERM or SIGHUP (e.g., because a
test was hanging and the user 'kill'-ed it or simply closed the
terminal window the test was running in), the shell exits immediately.
This can be annoying if the test script did any global setup, like
starting apache or git-daemon, as it will not have an opportunity to
clean up after itself. A subsequent run of the test won't be able to
start its own daemon, and will either fail or skip the tests.
Instead, let's trap SIGTERM and SIGHUP as well to make sure we do a
clean shutdown, and just chain it to a normal exit (which will trigger
any cleanup).

test-lib: check Bash version for '-x' without using shell arrays
One of our test scripts, 't1510-repo-setup.sh' [1], still can't be

Bash version supporting BASH_XTRACEFD (since v4.1). We have a lengthy

This condition uses non-portable shell array accesses to easily get
Bash's major and minor version number. This didn't seem to be
problematic, because the simple commands expanding those array
accesses are only executed when the test script is actually run with
Bash. When run with Dash, the only shell I have at hand that doesn't
support shell arrays, there are no issues, as it apparently skips
right over the non-executed simple commands without noticing the
non-supported constructs.
Alas, it has been reported that NetBSD's /bin/sh does complain about
them:
./test-lib.sh: 327: Syntax error: Bad substitution
where line 327 contains the first ${BASH_VERSINFO[0]} array access.
To my understanding both shells are right and conform to POSIX,
because the standard allows both behaviors by stating the following
under '2.8.1 Consequences of Shell Errors' [3]:
"An expansion error is one that occurs when the shell expansions
define in wordexp are carried out (for example, "${x!y}", because
'!' is not a valid operator); an implementation may treat these as
syntax errors if it is able to detect them during tokenization,
rather than during expansion."
Avoid this issue with NetBSD's /bin/sh (and potentially with other,
less common shells) by hiding the shell array syntax behind 'eval'
that is only executed with Bash.

range-diff: always pass at least minimal diff options
Commit d8981c3f88 ("format-patch: do not let its diff-options affect
--range-diff", 2018-11-30) taught `show_range_diff()` to accept a
NULL-pointer as an indication that it should use its own "reasonable
default". That fixed a regression from a5170794 ("Merge branch
'ab/range-diff-no-patch'", 2018-11-18), but unfortunately it introduced
a regression of its own.
In particular, it means we forget the `file` member of the diff options,
so rather than placing a range-diff in the cover-letter, we write it to
stdout. In order to fix this, rewrite the two callers adjusted by d8981c3f88 to instead create a "dummy" set of diff options where they
only fill in the fields we absolutely require, such as output file and
color.
Modify and extend the existing tests to try and verify that the right
contents end up in the right place.
Don't revert `show_range_diff()`, i.e., let it keep accepting NULL.
Rather than removing what is dead code and figuring out it isn't
actually dead and we've broken 2.20, just leave it for now.

rebase --stat: fix when rebasing to an unrelated history
When rebasing to a commit history that has no common commits with the

Also, if running in verbose diffstat mode, we should not output

Test scripts checking 'git daemon' stop the daemon with a TERM signal,

This check is bogus since 03c39b3458 (t/lib-git-daemon: use

- Right after killing 'git daemon', 'stop_git_daemon' saves its exit
status in a variable, but since 03c39b3458 the condition checking
the exit status looks at '$?', which at this point is not the exit
status of 'git daemon', but that of the variable assignment, i.e.
it's always 0.
- The unexpected exit status should abort the whole test script with
