d0b8a61742 tests: make test_might_fail fail on missing commands
Detect and report hard-to-notice spelling mistakes like

 test_might_fail "git config --unset whatever"

(the extra quotes prevent the shell from running git as intended;
instead, the shell looks for a "git config --unset whatever" file).

a54ce3ca9e tests: make test_must_fail fail on missing commands
The point of it is to run a command that produces failure. A
missing command is more likely an error in the test script
(e.g., using 'test_must_fail "command with arguments"', or

ce518bbd6c Fix compat/regex ANSIfication on MinGW
compat/regexec.c had a weird combination of function declaration in ANSI
style and function definition in K&R style, for example:

 static unsigned
 re_copy_regs (struct re_registers *regs, regmatch_t *pmatch,
      int nregs, int regs_allocated) internal_function;

 static unsigned
 re_copy_regs (regs, pmatch, nregs, regs_allocated)
     struct re_registers *regs;
     regmatch_t *pmatch;
     int nregs, regs_allocated;
 { ... }

with this #define:

 #ifndef _LIBC
 # ifdef __i386__
 #  define internal_function   __attribute ((regparm (3), stdcall))
 # else
 #  define internal_function
 # endif
 #endif

The original version as shown above was fine, but with the ANSIfied
function definition and in the case where internal_function is not empty,
gcc identifies the declaration and definition as different and bails out.

Adding internal_function to the definition doesn't help (it results in
a syntax error); hence, remove it from the subset of declarations that gcc
flags as erroneous.

3ee1757bae builtin/fetch.c: ignore merge config when not fetching from branch's remote
When 'git fetch' is supplied a single argument, it tries to match it
against a configured remote and then fetch the refs specified by the
named remote's fetchspec.  Additionally, or alternatively, if the current
branch has a merge ref configured, and if the name of the remote supplied
to fetch matches the one in the branch's configuration, then git also adds
the merge ref to the list of refs to update.

If the argument to fetch does not specify a named remote, or if the name
supplied does not match the remote configured for the current branch, then
the current branch's merge configuration should not be considered.

git currently mishandles the case when the argument to fetch specifies a
GIT URL(i.e. not a named remote) and the current branch has a configured
merge ref.  In this case, fetch should ignore the branch's merge ref and
attempt to fetch from the remote repository's HEAD branch.  But, since
fetch only checks _whether_ the current branch has a merge ref configured,
and does _not_ check whether the branch's configured remote matches the
command line argument (until later), it will mistakenly enter the wrong
branch of an 'if' statement and will not fall back to fetch the HEAD branch.
The fetch ends up doing nothing and returns with a successful zero status.

Fix this by comparing the remote repository's name to the branch's remote
name, in addition to whether it has a configured merge ref, sooner, so that
fetch can correctly decide whether the branch's configuration is interesting
or not, and fall back to fetching from the remote's HEAD branch when
appropriate.

This fixes the test in t5510.

6106ce4669 t/t5510: demonstrate failure to fetch when current branch has merge ref
When 'git fetch' is supplied just a repository URL (not a remote name),
and without a fetch refspec, it should fetch from the remote HEAD branch
and update FETCH_HEAD with the fetched ref.  Currently, when 'git fetch'
is called like this, it fails to retrieve anything, and does not update
FETCH_HEAD, if the current checked-out branch has a configured merge ref.

i.e. this fetch fails to retrieve anything nor update FETCH_HEAD:

   git checkout master
   git config branch.master.merge refs/heads/master
   git fetch git://git.kernel.org/pub/scm/git/git.git

but this one does:

   git config --unset branch.master.merge
   git fetch git://git.kernel.org/pub/scm/git/git.git

Add a test to demonstrate this flaw.

175f6e59f6 checkout: respect diff.ignoreSubmodules setting
When 'git checkout' reports uncommitted changes, it also does so for
submodules.

The default mode is now to look really hard into submodules, not only
for different commits, but also for modified files. Since this can be
pretty expensive when there are a lot (and large) submodules, there is
the diff.ignoreSubmodules option.

Let's respect that setting when 'git checkout' reports the uncommitted
changes, since it does nothing else than a 'git diff --name-status'.

1fda91b511 Fix 'git log' early pager startup error case
We start the pager too early for several git commands, which results in
the errors sometimes going to the pager rather than show up as errors.

This is often hidden by the fact that we pass in '-X' to less by default,
which causes 'less' to exit for small output, but if you do

  export LESS=-S

you can then clearly see the problem by doing

  git log --prretty

which shows the error message ("fatal: unrecognized argument: --prretty")
being sent to the pager.

This happens for pretty much all git commands that use USE_PAGER, and then
check arguments separately. But "git diff" does it too early too (even
though it does an explicit setup_pager() call)

This only fixes it for the trivial "git log" family case.

e6eedc31d5 rev-parse: exit with non-zero status if ref@{n} is not valid.
"The current behaviour of ref@{...} syntax parser is suboptimal:

It even knows that it is running off the cut-off point; it should just
cause the caller to notice that fact.  I don't think changing it to error

With this change:

2b64fc894d pass "git -c foo=bar" params through environment
Git uses the "-c foo=bar" parameters to set a config
variable for a single git invocation. We currently do this
by making a list in the current process and consulting that
list in git_config.

This works fine for built-ins, but the config changes are
silently ignored by subprocesses, including dashed externals
and invocations to "git config" from shell scripts.

This patch instead puts them in an environment variable
which we consult when looking at config (both internally and
via calls "git config").

506049c7df fix >4GiB source delta assertion failure
When people try insane things such as delta-compressing 4GiB files, they
get this assertion:

diff-delta.c:285: create_delta_index: Assertion `packed_entry - (struct index_entry *)mem == entries' failed.

This happens because:

1) the 'entries' variable is an unsigned int

2) it is assigned with entries = (bufsize - 1) / RABIN_WINDOW
   (that itself is not a problem unless bufsize > 4G * RABIN_WINDOW)

3) the buffer is indexed from top to bottom starting at
   "data = buffer + entries * RABIN_WINDOW" and the multiplication
   here does indeed overflows, making the resulting top of the buffer
   much lower than expected.

This makes the number of actually produced index entries smaller than
what was computed initially, hence the assertion.

Furthermore, the current delta encoding format cannot represent offsets
into a reference buffer with more than 32 bits anyway.  So let's just
limit the number of entries to what the delta format can encode.

This commit refactors git stash show to make use of the assert_stash_like function.

git show now dies if the presented argument is non-stash-like.

Previous behaviour was to tolerate commits that were not even stash-like.

Previously, git stash show would accept stash-like arguments, but
only if there was a stash on the stack.

Now, git stash accepts stash-like arguments always and only fails
if no stash-like argument is specified and there is no stash stack.

fb433dc912 detached-stash: simplify git stash branch
This patch teaches git stash branch to tolerate stash-like arguments.

In particular, a stash is only required if an argument isn't specified
and the stash is only dropped if a stash entry reference was
specified or implied.

The implementation has been simplified by taking advantage of
assert_stash_like() and the variables established by
parse_flags_and_rev().

f276872d89 detached-stash: refactor git stash pop implementation
git stash pop is abstracted into its own implementation function - pop_stash.

The behaviour is changed so that git stash pop fails early if the
the specified stash reference does not exist or does not refer to
an extant entry in the reflog of the reference stash.

This fixes the case where the apply succeeds, but the drop fails.
Previously this caused caused git stash pop to exit with a non-zero exit code
and a dirty tree.

Now, git stash pop fails with a non-zero exit code, but the working
tree is not modified.
