a6ee883b8e t6044: new merge testcases for when index doesn't match HEAD
With one exception, we require the index to exactly match the
current HEAD commit at the time git merge is invoked.  This
expectation was even documented in git-merge.txt until commit
ebef7e5 (Documentation: simplify How Merge Works, 2010-01-23).

Most merge strategies enforced this requirement, but it turns out
not all did.  The current exceptions were the following two:

  * ff updates
  * octopus merges

ff updates actually will error out if the staged change is to a path
modified between HEAD and the commit being merged.  If the path(s)
that are staged are files unrelated to the changes between these two
commits, though, then an ff update will just keep these staged
changes around after the merge.  This is the one exception we
expected to the abort-merge-if- index-doesn't-match-HEAD rule.

For octopus merges, the rule should be enforced.  Unfortunately, the
current behavior of the code is to ignore the difference and use the
staged changes in place of whatever is in HEAD as it proceeds to
perform the merge.  So if the staged changes can be cleanly merged
with all the other heads, then the staged changes will just be
incorported into the resulting commit.  If the staged changes cannot
be cleanly merged with all the other heads, the merge is not aborted
-- merge conflicts are simply reported as if HEAD had originally
contained whatever the index did.

Add testcases that check our expectations.  A subsequent commit will
correct the erroneous octopus merge behavior.

40d71940b6 builtin/merge.c: fix a bug with trivial merges
If read_tree_trivial() succeeds and produces a tree that is already
in the object store, then the index is not written to disk, leaving
it out-of-sync with both HEAD and the working tree.

In order to write the index back out to disk after a merge,
write_index_locked() needs to be called.  For most merge strategies, this
is done from try_merge_strategy().  For fast forward updates, this is
done from checkout_fast_forward().  When trivial merges work, the call to
write_index_locked() is buried a little deeper:

  merge_trivial()
  -> write_tree_trivial()
     -> write_cache_as_tree()
        -> write_index_as_tree()
           -> write_locked_index()

However, it is only called when !cache_tree_fully_valid(), which is how
this bug is triggered.  But that also shows why this bug doesn't affect
any other merge strategies or cases.

Add a direct call to write_index_locked() from merge_trivial() to fix
this issue.  Since the indirect call to write_locked_index() was
conditional on cache_tree_fully_valid(), it won't be written twice.

ef7d3621d7 t7605: add a testcase demonstrating a bug with trivial merges
Repeating a trivial merge more than once will leave the index out of
sync, despite being clean before the merge and operating on the
exact same heads as the first run.  The recorded merge has the
correct tree and the working tree is brought up to date, it is just
the index that is left as it was before the merge.  Every attempt to
repeat the merge beyond the first will leave the index in the same
weird out-of-sync state.

7bec7f50ae t3404: use write_script
The test uses hardcoded #!/bin/sh to create a pre-commit hook
script.  Because the generated script uses $(command substitution),
which is not supported by /bin/sh on some platforms (e.g. Solaris),
the resulting pre-commit always fails.

Which is not noticeable as the test that uses the hook is about
checking the behaviour of the command when the hook fails ;-), but
nevertheless it is not testing what we wanted to test.

Use write_script so that the resulting script is run under the same
shell our scripted Porcelain commands are run, which must support
the necessary $(construct).

a3bb8ca74c t1020: do not overuse printf and use write_script
The test prepares a sample file "dir/two" with a single incomplete
line in it with "printf", and also prepares a small helper script
"diff" to create a file with a single incomplete line in it, again
with "printf".  The output from the latter is compared with an
expected output, again prepared with "printf" hence lacking the
final LF.  There is no reason for this test to be using files with
an incomplete line at the end, and these look more like a mistake
of not using

	printf "%s\n" "string to be written"

and using

	printf "string to be written"

Depending on what would be in $GIT_PREFIX, using the latter form
could be a bug waiting to happen.  Correct them.

Also, the test uses hardcoded #!/bin/sh to create a small helper
script.  For a small task like what the generated script does, it
does not matter too much in that what appears as /bin/sh would not
be _so_ broken, but while we are at it, use write_script instead,
which happens to make the result easier to read by reducing need
of one level of quoting.

ca386ee177 t5532: use write_script
The recent cleanup in b7cbbff switched t5532's use of
backticks to $(). This matches our normal shell style, which
is good. But it also breaks the test on Solaris, where
/bin/sh does not understand $().

Our normal shell style assumes a modern-ish shell which
knows about $(). However, some tests create small helper
scripts and just write "#!/bin/sh" into them. These scripts
either need to go back to using backticks, or they need to
respect $SHELL_PATH. The easiest way to do the latter is to
use write_script.

While we're at it, let's also stick the script creation
inside a test_expect block (our usual style), and split the
perl snippet into its own script (to prevent quoting
madness).

42a38cf788 read_raw_ref(): manage own scratch space
Instead of creating scratch space in resolve_ref_unsafe() and passing
it down through resolve_ref_1 to read_raw_ref(), teach read_raw_ref()
to manage its own scratch space. This reduces coupling across the
functions at the cost of some extra allocations.

Also, when read_raw_ref() is implemented for different reference
backends, the other implementations might have different scratch
space requirements.

Note that we now preserve errno across the calls to strbuf_release(),
which calls free() and can thus theoretically overwrite errno.
