sum(1) is a command for calculating checksums of the contents of files.
It was part of early editions of Unix ("Research Unix", 1972/1973, [1]).
cksum(1) appeared in 4.4BSD (1993) as a replacement [2], and became part
of POSIX.1-2008 [3]. OpenBSD 5.6 (2014) removed sum(1).
We only use sum(1) in t1002 to check for changes in three files. On
MinGW we use md5sum(1) instead. We could switch to the standard command
cksum(1) for all platforms; MinGW comes with GNU coreutils now, which
provides sum(1), cksum(1) and md5sum(1). Use our standard method for
checking for file changes instead: test_cmp.
It's more convenient because it shows differences nicely, it's faster on
MinGW because we have a special implementation there based only on
shell-internal commands, it's simpler as it allows us to avoid stripping
out unnecessary entries from the checksum file using grep(1), and it's
more consistent with the rest of the test suite.
We already compare changed files with their expected new contents using
diff(1), so we don't need to check with "test_must_fail test_cmp" if
they differ from their original state. A later patch could convert the
direct diff(1) calls to test_cmp as well.
With all sum(1) calls gone, remove the MinGW-specific implementation
from test-lib.sh as well.

Some tests run diff or grep to produce an output, and then
compare the output to an expected value. We know the exit
code we expect these processes to have (e.g., grep yields 0
if it produced output and 1 otherwise), so it would not make
the test wrong to look for it. But the difference between
their output and the expected output (e.g., shown by
test_cmp) is much more useful to somebody debugging the test
than the test just bailing out.
These tests break the &&-chain to skip the exit-code check
of the process. However, we can get the same effect by using
test_might_fail. Note that in some cases the test did use
"|| return 1", which meant the test was not wrong, but it
did fool --chain-lint.

The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.
The backquoted form is the traditional method for command
substitution, and is supported by POSIX. However, all but the
simplest uses become complicated quickly. In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.
The patch was generated by:
for _f in $(find . -name "*.sh")
do
sed -i 's@`\(.*\)`@$(\1)@g' ${_f}
done
and then carefully proof-read.

The option can be used to check if read-tree with the same set of other
options like "-m" and "-u" would succeed without actually changing either
the index or the working tree.
The relevant tests in the t10?? range were extended to do a read-tree -n
before the real read-tree to make sure neither the index nor any local
files were changed with -n and the same exit code as without -n is
returned. The helper functions added for that purpose reside in the new
t/lib-read-tree.sh file.
The only exception is #13 in t1004 ("unlinking an un-unlink-able
symlink"). As this is an issue of wrong directory permissions it is not
detected with -n.

Some old platforms have an old diff which doesn't have the -U option.
'git diff' can be used in its place. Adjust the comparison function to

As a general principle, we should not use "git diff" to validate the
results of what git command that is being tested has done. We would not
know if we are testing the command in question, or locating a bug in the
cute hack of "git diff --no-index".
Rather use test_cmp for that purpose.

Now that "git diff" handles stdin and relative paths outside the
working tree correctly, we can convert all instances of "diff -u"
to "git diff".

When a merge results in a creation of a path that did not exist
in HEAD, and if you already have that path on the working tree,
because the index has not been told about the working tree file,
read-tree happily removes it. The issue was brought up by Santi
Béjar on the list.

This is the first installment to libify diff brothers.
The updated diff-files uses revision.c::setup_revisions()
infrastructure to parse its command line arguments, which means
the pathname arguments are checked more strictly than before.
The tests are adjusted to separate possibly missing paths from
the rest of arguments with double-dashes, to show the kosher
way.
As Linus pointed out, renaming diff.c to diff-lib.c was simply
stupid, so I am renaming it back. The new diff-lib.c is to
contain pieces extracted from diff brothers.

As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.

I have noticed that "make test" fails without any explanations when the
"merge" utility is missing. I don't think tests should be silent in
case of failure.
It turned out that the particular test was using "exit" to interrupt the
test in case of an error. This caused the whole test script to exit.
No further tests would be run even if "--immediate" wasn't specified.
No error message was printed.
This patch does following:
All instances of "exit", "exit 1" and "(exit 1)" in tests have been
replaced with "return 1". In fact, "(exit 1)" had no effect.
File descriptor 5 is duplicated from file descriptor 1. This is needed
to print important error messages from tests.
New function test_run_() has been introduced. Any "return" in the test
would merely cause that function to return without skipping calls to
test_failure_() and test_ok_(). The new function also traps "exit" and
treats it like a fatal error (in case somebody reintroduces "exit" in
the tests).
test_expect_failure() and test_expect_success() check both the result of
eval and the return value of test_run_(). If the later is not 0, it's
always a failure because it indicates the the test didn't complete.

This replaces sha1sum(1) with sum(1) in t/t1002. GNU sum(1) runs in
"BSD compatibility" mode by default, and not all systems have GNU
coreutils. On any system without GNU coreutils (or sha1sum) t1002 will
fail. This patch should make t1002 complete successfully everywhere
that sum(1) runs.
I've tested this on Darwin and Linux; it works on both platforms.

results for both successful cases (earlier one checked the
result for only one of them). Also fixes typos in t1002 that
broke '&&' chain, potentially missing a test failure before the

This implements the "never lose the current cache information or
