Change the internal USE_LIBPCRE define, & build options flag to use a
naming convention ending in PCRE1, without changing the long-standing
USE_LIBPCRE Makefile flag which enables this code.
This is for preparation for libpcre2 support where having things like
USE_LIBPCRE and USE_LIBPCRE2 in any more places than we absolutely
need to for backwards compatibility with old Makefile arguments would
be confusing.
In some ways it would be better to change everything that now uses
USE_LIBPCRE to use USE_LIBPCRE1, and to make specifying
USE_LIBPCRE (or --with-pcre) an error. This would impose a one-time
burden on packagers of git to s/USE_LIBPCRE/USE_LIBPCRE1/ in their
build scripts.
However I'd like to leave the door open to making
USE_LIBPCRE=YesPlease eventually mean USE_LIBPCRE2=YesPlease,
i.e. once PCRE v2 is ubiquitous enough that it makes sense to make it
the default.
This code and the USE_LIBPCRE Makefile argument was added in commit
63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09). At the time there was
no indication that the PCRE project would release an entirely new &
incompatible API around 3 years later.

Because TAP output does not like to see the remainder of the test
getting skipped after running one or more tests, bf4b7219
("test-lib.sh: Add check for invalid use of 'skip_all' facility",

Instead, loosen the check so that we only pretend that the rest of
the test script did not exist in such a case. We'd lose a bit of

tests), but not very much (i.e. TAP wasn't told how many tests are

Some platforms have ulong that is smaller than time_t, and our
historical use of ulong for timestamp would mean they cannot
represent some timestamp that the platform allows. Invent a

The convention "$remove_trash is set to the trash directory that is
used during the test, so that it will be removed at the end, but
under --debug option we set the varilable to empty string to
preserve the directory" made sense back when it was introduced, as
there was no $TRASH_DIRECTORY variable. These days, since no tests
looks at the variable, it is obscure and even risks that by mistake
the variable gets used for something else (e.g. remove_trash=yes)
and cause us misbehave. Worse yet, remove_trash was not initialized
to an empty string at the beginning, so a stray environment variable
the user has could have affected the logic when "--debug" is in use.
Rewrite the clean-up sequence in test_done helper to explicitly
check the $debug condition and remove the trash directory using
the $TRASH_DIRECTORY variable.
Note that "go to the directory one level above the trash and then
remove it" is kept and this is deliverate; test_at_end_hook_ will
keep running from the expected location, and also some platforms may
not like a directory that is serving as the $cwd of a still-active

these errors are ignored during housekeeping in 'test_done'.
However, such an error is a sign that something is fishy in the test

Git's source code refers to timestamps as unsigned long, which is

In preparation of switching to another data type that is large enough

Git's source code refers to timestamps as unsigned longs. On 32-bit
platforms, as well as on Windows, unsigned long is not large enough to
capture dates that are "absurdly far in the future".
It is perfectly valid by the C standard, of course, for the `long` data
type to refer to 32-bit integers. That is why the `time_t` data type
exists: so that it can be 64-bit even if `long` is 32-bit. Git's source
code simply uses an incorrect data type for timestamps, is all.
The earlier quick fix 6b9c38e14c (t0006: skip "far in the future" test
when unsigned long is not long enough, 2016-07-11) papered over this
issue simply by skipping the respective test cases on platforms where
they would fail due to the data type in use.
This quick fix, however, tests for *long* to be 64-bit or not. What we
need, though, is a test that says whether *whatever data type we use for
timestamps* is 64-bit or not.
The same quick fix was used to handle the similar problem where Git's
source code uses `unsigned long` to represent size, instead of `size_t`,
conflating the two issues.
So let's just add another prerequisite to test specifically whether
timestamps are represented by a 64-bit data type or not. Later, after we
switch to a larger data type, we can flip that prerequisite to test
`time_t` instead of `long`.

The 'debug' test helper is supposed to facilitate debugging by running
a command of the test suite under gdb. Unfortunately, its usefulness
is severely limited, because that gdb session is not interactive,
since the test's, and thus gdb's standard input is redirected from
/dev/null (for a good reason, see 781f76b15 (test-lib: redirect stdin
of tests, 2011-12-15)).
Redirect gdb's standard file descriptors from/to the test
environment's stdin, stdout and stderr in the 'debug' helper, thus
creating an interactive gdb session (even in non-verbose mode), which
is much, much more useful.

When there is a TAP harness consuming the output of our test
scripts, the "--verbose" breaks the output by mingling
test command output with TAP. Because the TAP::Harness
module used by "prove" is fairly lenient, this _usually_
works, but it violates the spec, and things get very
confusing if the commands happen to output a line that looks
like TAP (e.g., the word "ok" on its own line).
Let's detect this situation and complain. Just calling
error() isn't great, though; prove will tell us that the
script failed, but the message doesn't make it through to
the user. Instead, we can use the special TAP signal "Bail
out!". This not only shows the message to the user, but
instructs the harness to stop running the tests entirely.
This is exactly what we want here, as the problem is in the
command-line options, and every test script would produce
the same error.
The result looks like this (the first "Bailout called" line
is in red if prove uses color on your terminal):
$ make GIT_TEST_OPTS='--verbose --tee'
rm -f -r 'test-results'
*** prove ***
Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log

The "--verbose" option redirects output from arbitrary
test commands to stdout. This is useful for examining the
output manually, like:
./t5547-push-quarantine.sh -v | less
But it also means that the output is intermingled with the
TAP directives, which can confuse a TAP parser like "prove".
This has always been a potential problem, but became an
issue recently when one test happened to output the word
"ok" on a line by itself, which prove interprets as a test
success:
$ prove t5547-push-quarantine.sh :: -v
t5547-push-quarantine.sh .. 1/? To dest.git

Result: FAIL
One answer is "if it hurts, don't do it", but that's not
quite the whole story. The Travis tests use "--verbose
--tee" so that they can get the benefit of prove's parallel
options, along with a verbose log in case there is a
failure. We just need the verbose output to go to the log,
but keep stdout clean.
Getting this right turns out to be surprisingly difficult.
Here's the progression of alternatives I considered:
1. Add an option to write verbose output to stderr. This is
hard to capture, though, because we want each test to
have its own log (because they're all run in parallel
and the jumbled output would be useless).
2. Add an option to write verbose output to a file in
test-results. This works, but the log is missing all of
the non-verbose output, which gives context.
3. Like (2), but teach say_color() to additionally output
to the log. This mostly works, but misses any output
that happens outside of the say() functions (which isn't
a lot, but is a potential maintenance headache).
4. Like (2), but make the log file the same as the "--tee"
file. That almost works, but now we have two processes
opening the same file. That gives us two separate
descriptors, each with their own idea of the current
position. They'll each start writing at offset 0, and
overwrite each other's data.
5. Like (4), but in each case open the file for appending.
That atomically positions each write at the end of the
file.
It's possible we may still get sheared writes between
the two processes, but this is already the case when
writing to stdout. It's not a problem in practice
because the test harness generally waits for snippets to
finish before writing the TAP output.
We can ignore buffering issues with tee, because POSIX
mandates that it does not buffer. Likewise, POSIX
specifies "tee -a", so it should be available
everywhere.
This patch implements option (5), which seems to work well
in practice.

Each test run generates a "count" file in t/test-results
that stores the number of successful, failed, etc tests.
If you run "t1234-foo.sh", that file is named as
"t/test-results/t1234-foo-$$.count"
The addition of the PID there is serving no purpose, and
makes analysis of the count files harder.
The presence of the PID dates back to 2d84e9f (Modify
test-lib.sh to output stats to t/test-results/*,
2008-06-08), but no reasoning is given there. Looking at the
current code, we can see that other files we write to
test-results (like *.exit and *.out) do _not_ have the PID
included. So the presence of the PID does not meaningfully
allow one to store the results from multiple runs anyway.
Moreover, anybody wishing to read the *.count files to
aggregate results has to deal with the presence of multiple
files for a given test (and figure out which one is the most
recent based on their timestamps!). The only consumer of
these files is the aggregate.sh script, which arguably gets
this wrong. If a test is run multiple times, its counts will
appear multiple times in the total (I say arguably only
because the desired semantics aren't documented anywhere,
but I have trouble seeing how this behavior could be
useful).
So let's just drop the PID, which fixes aggregate.sh, and
will make new features based around the count files easier
to write.
Note that since the count-file may already exist (when
re-running a test), we also switch the "cat" from appending
to truncating. The use of append here was pointless in the
first place, as we expected to always write to a unique file.

* jk/test-send-sh-x-trace-elsewhere:
test-lib: set BASH_XTRACEFD automatically
Passing "-x" to a test script enables the shell's "set -x"
tracing, which can help with tracking down the command that
is causing a failure. Unfortunately, it can also _cause_
failures in some tests that redirect the stderr of a shell
function. Inside the function the shell continues to
respect "set -x", and the trace output is collected along
with whatever stderr is generated normally by the function.
You can see an example of this by running:
./t0040-parse-options.sh -x -i
which will fail immediately in the first test, as it
expects:
test_must_fail some-cmd 2>output.err
to leave output.err empty (but with "-x" it has our trace
output).
Unfortunately there isn't a portable or scalable solution to
this. We could teach test_must_fail to disable "set -x", but
that doesn't help any of the other functions or subshells.
However, we can work around it by pointing the "set -x"
output to our descriptor 4, which always points to the
original stderr of the test script. Unfortunately this only
works for bash, but it's better than nothing (and other
shells will just ignore the BASH_XTRACEFD variable).
The patch itself is a simple one-liner, but note the caveats
in the accompanying comments.
Automatic tests for our "-x" option may be a bit too meta
(and a pain, because they are bash-specific), but I did
confirm that it works correctly both with regular "-x" and
with "--verbose-only=1". This works because the latter flips
"set -x" off and on for particular tests (if it didn't, we
would get tracing for all tests, as going to descriptor 4
effectively circumvents the verbose flag).

On Windows, there is no SIGPIPE. A consequence of this is that the
upstream process of a pipe does not notice the death of the downstream
process until the pipe buffer is full and writing more data returns an
error. This behavior is the reason for an annoying delay during the
execution of t7610-mergetool.sh: There are a number of test cases where
'yes' is invoked upstream. Since the utility is basically an endless
loop it runs, on Windows, until the pipe buffer is full. This does take
a few seconds.
The test suite has its own implementation of 'yes'. Modify it to produce
only a limited amount of output that is sufficient for the test suite.
The amount chosen should be sufficiently high for any test case, assuming
that future test cases will not exaggerate their demands of input from
an upstream 'yes' invocation.

The description for SANITY prerequisite the test suite uses has
been clarified both in the comment and in the implementation.
* jk/sanity:
test-lib: clarify and tighten SANITY
MSYS2 (the POSIX emulation layer used by Git for Windows' Bash) actually
has a working mkfifo. The only problem is that it is only emulating
named pipes through the MSYS2 runtime; The Win32 API has no idea about
named pipes, hence the Git executable cannot access those pipes either.
The symptom is that Git fails with a '<name>: No such file or directory'
because MSYS2 emulates named pipes through special-crafted '.lnk' files.
The solution is to tell the test suite explicitly that we cannot use
named pipes when we want to test on Windows.
This lets t4056-diff-order.sh, t9010-svn-fe.sh and t9300-fast-import.sh
pass.

Running tests with the "-x" option to make them verbose had some
unpleasant interactions with other features of the test suite.
* jk/test-with-x:
test-lib: disable trace when test is not verbose
test-lib: turn off "-x" tracing during chain-lint check
The "-x" test-script option turns on the shell's "-x"
tracing, which can help show why a particular test is
failing. Unfortunately, this can create false negatives in
some tests if they invoke a shell function with its stderr
redirected. t5512.10 is such a test, as it does:
test_must_fail git ls-remote refs*master >actual 2>&1 &&
test_cmp exp actual
The "actual" file gets the "-x" trace for the test_must_fail
function, which prevents it from matching the expected
output.
There's no way to avoid this without managing the
trace flag inside each sub-function, which isn't really a
workable solution. But unless you specifically care about
t5512.10, we can work around it by enabling tracing only for
the specific tests we want.
You can already do:
./t5512-ls-remote.sh -x --verbose-only=16
to see the trace only for a specific test. But that doesn't
_disable_ the tracing in the other tests; it just sends it
to /dev/null. However, there's no point in generating a
trace that the user won't see, so we can simply disable
tracing whenever it doesn't have a matching verbose flag.
The normal case of just "./t5512-ls-remote.sh -x" stays the
same, as "-x" already implies "--verbose" (and
"--verbose-only" overrides "--verbose", which is why this
works at all). And for our test, we need only check
$verbose, as maybe_setup_verbose will have already
set that flag based on the $verbose_only list).

Now that GIT_TEST_CHAIN_LINT is on by default, running:

expecting success:

ok 1 - .git/objects should be empty after git init in an empty repo

(which is printed in red, no less!) are not part of the test
at all, but are rather in the separate chain-lint test_eval.
Let's unset the "trace" variable when eval-ing the chain
lint check, which avoids this.
Note that we cannot just do a one-shot variable like:

If tput needs ~/.terminfo for the current $TERM, then tput will
succeed before HOME is changed to $TRASH_DIRECTORY (causing color to
be set to 't') but fail afterward.
One possible way to fix this is to treat HOME like TERM: back up the
original value and temporarily restore it before say_color() runs
tput.
Instead, pre-compute and save the color control sequences before
changing either TERM or HOME. Use the saved control sequences in
say_color() rather than call tput each time. This avoids the need to
back up and restore the TERM and HOME variables, and it avoids the
overhead of a subshell and two invocations of tput per call to
say_color().

It's easy to miss an "&&"-chain in a test script, like:
test_expect_success 'check something important' '
cmd1 &&
cmd2
cmd3
'
The test harness will notice if cmd3 fails, but a failure of
cmd1 or cmd2 will go unnoticed, as their exit status is lost
after cmd3 runs.
The toy example above is easy to spot because the "cmds" are
all the same length, but real code is much more complicated.
It's also difficult to detect these situations by statically
analyzing the shell code with regexps (like the
check-non-portable-shell script does); there's too much
context required to know whether a &&-chain is appropriate
on a given line or not.
This patch instead lets the shell check each test by
sticking a command with a specific and unusual return code
at the top of each test, like:
(exit 117) &&
cmd1 &&
cmd2
cmd3
In a well-formed test, the non-zero exit from the first
command prevents any of the rest from being run, and the
test's exit code is 117. In a bad test (like the one above),
the 117 is lost, and cmd3 is run.
When we encounter a failure of this check, we abort the test
script entirely. For one thing, we have no clue which subset
of the commands in the test snippet were actually run.
Running further tests would be pointless, because we're now
in an unknown state. And two, this is not a "test failure"
in the traditional sense. The test script is buggy, not the
code it is testing. We should be able to fix these problems
in the script once, and not have them come back later as a
regression in git's code.
After checking a test snippet for --chain-lint, we do still
run the test itself. We could actually have a pure-lint
mode which just checks each test, but there are a few
reasons not to. One, because the tests are executing
arbitrary code, which could impact the later environment
(e.g., that could impact which set of tests we run at all).
And two, because a pure-lint mode would still be expensive
to run, because a significant amount of code runs outside of
the test_expect_* blocks. Instead, this option is designed
to be used as part of a normal test suite run, where it adds
very little overhead.
Turning on this option detects quite a few problems in
existing tests, which will be fixed in subsequent patches.
However, there are a number of places it cannot reach:
- it cannot find a failure to break out of loops on error,
like:
cmd1 &&
for i in a b c; do
cmd2 $i
done &&
cmd3
which will not notice failures of "cmd2 a" or "cmd b"
- it cannot find a missing &&-chain inside a block or
subfunction, like:
foo () {
cmd1
cmd2
}
foo &&
bar
which will not notice a failure of cmd1.
- it only checks tests that you run; every platform will
have some tests skipped due to missing prequisites,
so it's impossible to say from one run that the test
suite is free of broken &&-chains. However, all tests get
run by _somebody_, so eventually we will notice problems.
- it does not operate on test_when_finished or prerequisite
blocks. It could, but these tends to be much shorter and
less of a problem, so I punted on them in this patch.

If you run a test script like:
GIT_TRACE=1 ./t0061-run-command.sh
you may get test failures, because some tests capture and
check the stderr output from git commands (and with
GIT_TRACE set to 1, the trace output will be included
there).
When we see GIT_TRACE set like this, we print a warning to
the user. However, we can do even better than that by just
pointing it to descriptor 4, which all tests leave connected
to the test script's stderr. That's likely what the user
intended (and any scripts that do want to see GIT_TRACE
output will set GIT_TRACE themselves).
Not only does this avoid false negatives in the tests, but
it means the user will actually see trace output for git
calls that redirect their stderr (whereas before, it was
sometimes confusingly buried in a file).

Right now if a test script receives SIGINT (e.g., because a
test was hanging and the user hit ^C), 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 SIGINT to make sure we do a clean
shutdown, and just chain it to a normal exit (which will
trigger any cleanup).

- You should not be able to remove a file in a read-only directory,
- You should not be able to tell if a file in a directory exists if
the directory lacks read or execute permission bits.
We used to cheat by approximating that condition with "is the /

is sufficient or appropriate in environments like Cygwin.

The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).
Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.
We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS. Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:
1. we know we are root
2. we know we are not root
3. we could not tell, because `id` was not available
We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

If ncurses needs ~/.terminfo for the current $TERM, then tput will
succeed before changing HOME to $TRASH_DIRECTORY but fail afterward.
Move the tests that determine whether there is color support after
changing HOME so that color=t is set if and only if tput would succeed
when say_color() is run.
Note that color=t is now set after --no-color is processed, so the
condition to set color=t has changed: it is now set only if
color has not already been set to the empty string by --no-color.
This disables color support for those that need ~/.terminfo for
their TERM, but it's better than filling the screen with:
tput: unknown terminal "custom-terminal-name-here"
An alternative would be to symlink or copy the user's terminfo
database into $TRASH_DIRECTORY, but this is tricky due to the lack of
a standard name for the terminfo database (for example, instead of a
~/.terminfo directory, NetBSD uses a ~/.terminfo.cdb database file).

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for HFS+;
let's use it in verify_path.
We make this check optional for two reasons:
1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on HFS+. In practice
this probably doesn't matter, though, as the restricted
names are rather obscure and almost certainly would
never come up in practice.
2. It has a minor performance penalty for every path we
insert into the index.
This patch ties the check to the core.protectHFS config
option. Though this is expected to be most useful on OS X,
we allow it to be set everywhere, as HFS+ may be mounted on
other platforms. The variable does default to on for OS X,
though.

When git is compiled with "-fsanitize=address" (using clang
or gcc >= 4.8), all invocations of git will check for buffer
overflows. This is similar to running with valgrind, except
that it is more thorough (because of the compiler support,
function-local buffers can be checked, too) and runs much
faster (making it much less painful to run the whole test
suite with the checks turned on).
Unlike valgrind, the magic happens at compile-time, so we
don't need the same infrastructure in the test suite that we
did to support --valgrind. But there are two things we can
help with:
1. On some platforms, the leak-detector is on by default,
and causes every invocation of "git init" (and thus
every test script) to fail. Since running git with
the leak detector is pointless, let's shut it off
automatically in the tests, unless the user has already
configured it.
2. When apache runs a CGI, it clears the environment of
unknown variables. This means that the $ASAN_OPTIONS
config doesn't make it to git-http-backend, and it
dies due to the leak detector. Let's mark the variable
as OK for apache to pass.
With these two changes, running
make CC=clang CFLAGS=-fsanitize=address test
works out of the box.

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.

MinGW: update tests to handle a native eol of crlf
Makefile: propagate NATIVE_CRLF to C
t0027: Tests for core.eol=native, eol=lf, eol=crlf
The "--signed" option received by "git push" is first passed to the
transport layer, which the native transport directly uses to notice
that a push certificate needs to be sent. When the transport-helper
is involved, however, the option needs to be told to the helper with
set_helper_option(), and the helper needs to take necessary action.
For the smart-HTTP helper, the "necessary action" involves spawning
the "git send-pack" subprocess with the "--signed" option.
Once the above all gets wired in, the smart-HTTP transport now can
use the push certificate mechanism to authenticate its pushes.
Add a test that is modeled after tests for the native transport in
t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test
Apache configuration to pass GNUPGHOME environment variable through.
As PassEnv would trigger warnings for an environment variable that
is not set, export it from test-lib.sh set to a harmless value when
GnuPG is not being used in the tests.
Note that the added test is deliberately loose and does not check
the nonce in this step. This is because the stateless RPC mode is
inevitably flaky and a nonce that comes back in the actual push
processing is one issued by a different process; if the two
interactions with the server crossed a second boundary, the nonces
will not match and such a check will fail. A later patch in the
series will work around this shortcoming.

t0000-*.sh: fix the GIT_SKIP_TESTS sub-tests
test-lib: '--run' to run only specific tests
test-lib: tests skipped by GIT_SKIP_TESTS say so

Two test scripts (t3302 and t3419) had copy & paste code to set
USR_BIN_TIME prerequisite. Use the test_lazy_prereq helper to define
them in the common t/test-lib.sh.

Allow better control of the set of tests that will be executed for a
single test suite. Mostly useful while debugging or developing as it
allows to focus on a specific test.

We used to show "(missing )" next to tests skipped because they are
specified in GIT_SKIP_TESTS. Use "(GIT_SKIP_TESTS)" instead.
Plus tests that check basic GIT_SKIP_TESTS functions.

Turning on this variable can be useful when debugging http
tests. It does break a few tests in t5541, but it is not
a variable that the user is likely to have enabled
accidentally.

* jk/tests-cleanup:
t0001: drop subshells just for "cd"
t0001: drop useless subshells
t0001: use test_must_fail
t0001: use test_config_global
t0001: use test_path_is_*
t0001: make symlink reinit test more careful
t: prefer "git config --file" to GIT_CONFIG
t: prefer "git config --file" to GIT_CONFIG with test_must_fail
t: stop using GIT_CONFIG to cross repo boundaries
t: drop useless sane_unset GIT_* calls
t/test-lib: drop redundant unset of GIT_CONFIG
t/Makefile: stop setting GIT_CONFIG
This is already handled by the mass GIT_* unsetting added by
95a1d12 (tests: scrub environment of GIT_* variables,
2011-03-15).

In some places we "echo" a string that is supplied by the calling
test script and may contain backslash sequences. The echo command
of some shells, most notably "dash", interprets these backslash
sequences (POSIX.1 allows this) which may scramble the test
output.

Allow adding a TEST_GIT_INDEX_VERSION variable to config.mak to set the
index version with which the test suite should be run.
If it isn't set, the default version given in the source code is
used (currently version 3).
To avoid breakages with index versions other than [23], also set the
index version under which t2104 is run to 3. This test only tests
functionality specific to version 2 and 3 of the index file and would
fail if the test suite is run with any other version.
