cfa96496bd git p4 test: translate windows paths for cygwin
Native windows binaries do not understand posix-like
path mapping offered by cygwin.  Convert paths to native
using "cygpath --windows" before presenting them to p4d.

This is done using the AltRoots mechanism of p4.  Both the
posix and windows forms are put in the client specification,
allowing p4 to find its location by native path even though
the environment reports a different PWD.

Shell operations in tests will use the normal form of $cli,
which will look like a posix path in cygwin, while p4 will
use AltRoots to match against the windows form of the working
directory.

This mechanism also handles the symlink issue that was fixed in
23bd0c9 (git p4 test: use real_path to resolve p4 client
symlinks, 2012-06-27).  Now that every p4 client view has
an AltRoots with the real_path in it, explicitly calculating
the real_path elsewhere is not necessary.

InfoZIP's unzip takes default parameters from the environment variable
UNZIP.  Unset it in the test library and use GIT_UNZIP for specifying
alternate versions of the unzip command instead.

t0024 wasn't even using variable for the actual extraction.  t5000
was, but when setting it to InfoZIP's unzip it would try to extract
from itself (because it treats the contents of $UNZIP as parameters),
which failed of course.

b73d9a2363 tests: paint unexpectedly fixed known breakages in bold red
Change color of unexpectedly fixed known breakages to bold red.  An
unexpectedly passing test indicates that the test code is somehow
broken or out of sync with the code it is testing.  Either way this is
an error which is potentially as bad as a failing test, and as such is
no longer portrayed as a pass in the output.

0a6d4751da tests: change info messages from yellow/brown to cyan
Now that we've adopted a "traffic lights" coloring scheme, yellow is
used for warning messages, so we need to re-color info messages to
something less alarmist.  Blue is a universal color for informational
messages; however we are using that for skipped tests in order to
align with the color schemes of other test suites.  Therefore we use
cyan which is also blue-ish, but visually distinct from blue.

This was suggested on the list a while ago and no-one raised any
objections:

    http://thread.gmane.org/gmane.comp.version-control.git/205675/focus=205966

An earlier iteration of this patch used bold cyan, but the point of
this change is to make them less alarming; let's drop the boldness.

Also paint the message to report skipping the whole thing via
GIT_SKIP_TESTS mechanism in the same color as the "info" color
that is used on the final summary line for the entire script.

e8e5195573 tests: paint known breakages in yellow
Yellow seems a more appropriate color than bold green when
considering the universal traffic lights coloring scheme, where
green conveys the impression that everything's OK, and amber that
something's not quite right.

Likewise, change the color of the summarized total number of known
breakages from bold red to the same yellow to be less alarmist and
more consistent with the above.

An earlier version of this patch used bold yellow but because these
are all long-known failures, reminding them to developers in bold
over and over does not help encouraging them to take a look at them
very much.  This iteration paints them in plain yellow instead to
make them less distracting.

The most important in this change is to avoid affecting anything
when test-lib is used from perf-lib.  It also limits the effect of

a731fa916e Add MALLOC_CHECK_ and MALLOC_PERTURB_ libc env to the test suite for detecting heap corruption
Recent versions of Linux libc (later than 5.4.23) and glibc (2.x)
include a malloc() implementation which is tunable via environment
variables. When MALLOC_CHECK_ is set, a special (less efficient)
implementation is used which is designed to be tolerant against
simple errors, such as double calls of free() with the same argument,
or overruns of a single byte (off-by-one bugs). When MALLOC_CHECK_
is set to 3, a diagnostic message is printed on stderr
and the program is aborted.

Setting the MALLOC_PERTURB_ environment variable causes the malloc
functions in libc to return memory which has been wiped and clear
memory when it is returned.
Of course this does not affect calloc which always does clear the memory.

The reason for this exercise is, of course, to find code which uses
memory returned by malloc without initializing it and code which uses
code after it is freed. valgrind can do this but it's costly to run.
The MALLOC_PERTURB_ exchanges the ability to detect problems in 100%
of the cases with speed.

The byte value used to initialize values returned by malloc is the byte
value of the environment value. The value used to clear memory is the
bitwise inverse. Setting MALLOC_PERTURB_ to zero disables the feature.

This technique can find hard to detect bugs.
It is therefore suggested to always use this flag (at least temporarily)
when testing out code or a new distribution.

But the test suite can use also valgrind(memcheck) via 'make valgrind'
or 'make GIT_TEST_OPTS="--valgrind"'.

Memcheck wraps client calls to malloc(), and puts a "red zone" on
each end of each block in order to detect access overruns.
Memcheck already detects double free() (up to the limit of the buffer
which remembers pending free()). Thus memcheck subsumes all the
documented coverage of MALLOC_CHECK_.

If MALLOC_CHECK_ is set non-zero when running memcheck, then the
overruns that might be detected by MALLOC_CHECK_ would be overruns
on the wrapped blocks which include the red zones.  Thus MALLOC_CHECK_
would be checking memcheck, and not the client.  This is not useful,
and actually is wasteful.  The only possible [documented] advantage
of using MALLOC_CHECK_ and memcheck together, would be if MALLOC_CHECK_
detected duplicate free() in more cases than memcheck because memcheck's
buffer is too small.

Therefore we don't use MALLOC_CHECK_ and valgrind(memcheck) at the
same time.

04083f278d test: allow prerequisite to be evaluated lazily
The test prerequisite mechanism is a useful way to allow some tests
in a test script to be skipped in environments that do not support
certain features (e.g. it is pointless to attempt checking how well
symbolic links are handled by Git on filesystems that do not support
them).  It is OK for commonly used prerequisites to be always tested
during start-up of a test script by having a codeblock that tests a
feature and calls test_set_prereq, but for an uncommon feature,
forcing 90% of scripts to pay the same probing overhead for
prerequisite they do not care about is wasteful.

Introduce a mechanism to probe the prerequiste lazily.  Changes are:

 - test_lazy_prereq () function, which takes the name of the
   prerequisite it probes and the script to probe for it, is
   added.  This only registers the name of the prerequiste that can
   be lazily probed and the script to eval (without running).

 - test_have_prereq() function (which is used by test_expect_success
   and also can be called directly by test scripts) learns to look
   at the list of prerequisites that can be lazily probed, and the
   prerequisites that have already been probed that way.  When asked
   for a prerequiste that can be but haven't been probed, the script
   registered with an earlier call to test_lazy_prereq is evaluated
   and the prerequisite is set.

 - test_run_lazy_prereq_() function is a helper to run the probe
   script with the same kind of sandbox as regular tests, helped by
   Jeff King.

Update the codeblock to probe and set SYMLINKS prerequisite using
the new mechanism as an example.

661bfd13b4 tests: fix spurious error when run directly with Solaris /usr/xpg4/bin/sh
If any test script is run directly with Solaris 10 /usr/xpg4/bin/sh or
/bin/ksh, it fails spuriously with a message like:

  t0000-basic.sh[31]: unset: bad argument count

This happens because those shells bail out when encountering a call to
"unset" with no arguments, and such unset call could take place in
'test-lib.sh'.  Fix that issue, and add a proper comment to ensure we
don't regress in this respect.

342e9ef2d9 Introduce a performance testing framework
This introduces a performance testing framework under t/perf/.  It
tries to be as close to the test-lib.sh infrastructure as possible,
and thus should be easy to get used to for git developers.

The following points were considered for the implementation:

1. You usually want to compare arbitrary revisions/build trees against
   each other.  They may not have the performance test under
   consideration, or even the perf-lib.sh infrastructure.

   To cope with this, the 'run' script lets you specify arbitrary
   build dirs and revisions.  It even automatically builds the revisions
   if it doesn't have them at hand yet.

2. Usually you would not want to run all tests.  It would take too
   long anyway.  The 'run' script lets you specify which tests to run;
   or you can also do it manually.  There is a Makefile for
   discoverability and 'make clean', but it is not meant for
   real-world use.

3. Creating test repos from scratch in every test is extremely
   time-consuming, and shipping or downloading such large/weird repos
   is out of the question.

   We leave this decision to the user.  Two different sizes of test
   repos can be configured, and the scripts just copy one or more of
   those (using hardlinks for the object store).  By default it tries
   to use the build tree's git.git repository.

   This is fairly fast and versatile.  Using a copy instead of a clone
   preserves many properties that the user may want to test for, such
   as lots of loose objects, unpacked refs, etc.

12a29b1a50 Move the user-facing test library to test-lib-functions.sh
This just moves all the user-facing functions to a separate file and
sources that instead.

840c519d7e tests: add write_script helper function
Many of the scripts in the test suite write small helper
shell scripts to disk. It's best if these shell scripts
start with "#!$SHELL_PATH" rather than "#!/bin/sh", because
/bin/sh on some platforms is too buggy to be used.

However, it can be cumbersome to expand $SHELL_PATH, because
the usual recipe for writing a script is:

	cat >foo.sh <<-\EOF
	#!/bin/sh
	echo my arguments are "$@"
	EOF

To expand $SHELL_PATH, you have to either interpolate the
here-doc (which would require quoting "\$@"), or split the
creation into two commands (interpolating the $SHELL_PATH
line, but not the rest of the script). Let's provide a
helper function that makes that less syntactically painful.

While we're at it, this helper can also take care of the
"chmod +x" that typically comes after the creation of such a
script, saving the caller a line.

f8246281af merge: use editor by default in interactive sessions
Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.

After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.

Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).

There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics.  GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.

Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

c4d2539af7 test-lib: add the test_pause convenience function
Since 781f76b15 (test-lib: redirect stdin of tests) you can't simply put a
"bash &&" into a test for debugging purposes anymore. Instead you'll have
to use "bash <&6 >&3 2>&4".

As that invocation is not that easy to remember add the test_pause
convenience function. It invokes "$SHELL_PATH" to provide a sane shell
for the user.

This function also checks if the -v flag is given and will error out if
that is not the case instead of letting the test hang until ^D is pressed.
