The reason for that bogus value is that '--total's parameter is parsed
via parse-options's OPT_INTEGER into a uint64_t variable [1], so the
two bits of 3 end up in the "wrong" bytes on big-endian systems
(12884901888 = 0x300000000).
Change the type of that variable from uint64_t to int, to match what
parse-options expects; in the tests of the progress output we won't
use values that don't fit into an int anyway.
[1] start_progress() expects the total number as an uint64_t, that's
why I chose the same type when declaring the variable holding the
value given on the command line.

Since these macros already take a `keyvar' pointer of a known type,
we can rely on OFFSETOF_VAR to get the correct offset without
relying on non-portable `__typeof__' and `offsetof'.

While we cannot rely on a `__typeof__' operator being portable
to use with `offsetof'; we can calculate the pointer offset
using an existing pointer and the address of a member using
pointer arithmetic for compilers without `__typeof__'.
This allows us to simplify usage of hashmap iterator macros
by not having to specify a type when a pointer of that type
is already given.
In the future, list iterator macros (e.g. list_for_each_entry)
may also be implemented using OFFSETOF_VAR to save hackers the
trouble of using container_of/list_entry macros and without
relying on non-portable `__typeof__'.

Git for Windows jumps through hoops to provide a development environment
that allows to build Git and to run its test suite. To that end, an
entire MSYS2 system, including GNU make and GCC is offered as "the Git
for Windows SDK". It does come at a price: an initial download of said
SDK weighs in with several hundreds of megabytes, and the unpacked SDK
occupies ~2GB of disk space.
A much more native development environment on Windows is Visual Studio.
To help contributors use that environment, we already have a Makefile
target `vcxproj` that generates a commit with project files (and other
generated files), and Git for Windows' `vs/master` branch is
continuously re-generated using that target.
The idea is to allow building Git in Visual Studio, and to run
individual tests using a Portable Git.
The one missing thing is a way to run the entire test suite: neither
`make` nor `prove` are required to run Git, therefore Git for Windows
does not support those commands in the Portable Git.
To help with that, add a simple test helper that exercises the
`run_processes_parallel()` function to allow for running test scripts in
parallel (which is really necessary, especially on Windows, as Git's
test suite takes such a long time to run).
This will also come in handy for the upcoming change to our Azure
Pipeline: we will use this helper in a Portable Git to test the Visual
Studio build of Git.

This patch conceptually reverts 44103f4197 (t/helper: ignore
everything but sources, 2017-12-12). Back in those days we did have a
lot of separate test helper executables under 't/helper', and its
'.gitignore' did get out of sync every once in a while.
Since then, however, most of those separate executables were
integrated into a single 'test-tool' command [1], and new test helpers
are added as new subcommands, so the chances of that '.gitignore'
getting out of sync again are much lower. And even if a contributor
were not careful enough and submits a patch that adds a new executable
under 't/helper' but forgets to update '.gitignore' accordingly, our
CI builds would catch it in a timely manner [2].
Ignoring everything but sources has the drawback that building an
older version of Git (e.g. during bisecting) creates all those
executables, and after going back to e.g. current 'master' the usual
cleanup commands like 'make clean' or 'git clean -fd' don't remove
them (the former doesn't know about them, and the latter doesn't
remove ignored files).
So let's ignore only the executable files under 't/helper/, i.e.
'test-tool' and the three other remaining executables that could not
be integrated into 'test-tool' (no need to ignore object files, as
they are already ignored by our toplevel '.gitignore').

'progress.c' has seen a few fixes recently [1], and, unfortunately,
some of those fixes required further fixes [2]. It seems it's time to
have a few tests focusing on the subtleties of the progress display.
Add the 'test-tool progress' subcommand to help testing the progress
display, reading instructions from standard input and turning them
into calls to the display_progress() and display_throughput()
functions with the given parameters.
The progress display is, however, critically dependent on timing,
because it's only updated once every second or, if the toal is known
in advance, every 1%, and there is the throughput rate as well. These
make the progress display far too undeterministic for testing as-is.
To address this, add a few testing-specific variables and functions to
'progress.c', allowing the the new test helper to:
- Disable the triggered-every-second SIGALRM and set the
'progress_update' flag explicitly based in the input instructions.
This way the progress line will be updated deterministically when
the test wants it to be updated.
- Specify the time elapsed since start_progress() to make the
throughput rate calculations deterministic.
Add the new test script 't0500-progress-display.sh' to check a few
simple cases with and without throughput, and that a shorter progress
line properly covers up the previously displayed line in different
situations.

lines, 2019-04-12) and 9f1fd84e15 (progress: clear previous

Early in the function we set "namelen = strlen(name)" if "name" is
non-NULL. Later, we use "namelen" only if "name" is non-NULL. However,
it's hard to immediately see this, and it seems to confuse gcc 9.2.1
(with "-flto" interestingly, though all of the involved logic is in
inline functions; it also triggers when building with ASan).
Let's simplify the code and remove the variable entirely. There's only
one use of namelen anyway, so we can just call strlen() then. It's true
this is in a loop, so we might execute strlen() more often. But:
- this is test code that only ever loops twice in our test suite (we
do loop 1000 times in a t/perf test, but without using this option).
- a decent compiler ought to be able to hoist that out of the loop
anyway (though I wouldn't count on gcc 9.2.1 doing so!)

dir_iterator_advance() is a large function with two nested loops. Let's
improve its readability factoring out three functions and simplifying
its mechanics. The refactored model will no longer depend on
level.initialized and level.dir_state to keep track of the iteration
state and will perform on a single loop.
Also, dir_iterator_begin() currently does not check if the given string
represents a valid directory path. Since the refactored model will have
to stat() the given path at initialization, let's also check for this
kind of error and make dir_iterator_begin() return NULL, on failures,
with errno appropriately set. And add tests for this new behavior.
Improve documentation at dir-iteration.h and code comments at
dir-iterator.c to reflect the changes and eliminate possible
ambiguities.
Finally, adjust refs/files-backend.c to check for now possible
dir_iterator_begin() failures.

This one is tricky.
When `core.fsmonitor` is set, a `refresh_index()` will not perform a
full scan of files that might be modified, but will query the fsmonitor
and refresh only the ones that have been actually touched.
Due to implementation details, the fsmonitor is queried in
`refresh_cache_ent()`, but of course it only has to be queried once, so
we set a flag when we did that. But when the index was discarded, we did
not re-set that flag.
So far, this is only covered by our test suite when running with
GIT_TEST_FSMONITOR=$PWD/t7519/fsmonitor-all, and only due to the way the
built-in stash interacts with the recursive merge machinery.
Let's introduce a straight-forward regression test for this.
We simply extend the "read & discard index" loop in `test-tool
read-cache` to optionally refresh the index, report on a given file's
status, and then modify that file. Due to the bug described above, only
the first refresh will actually query the fsmonitor; subsequent loop
iterations will not.

Change the option parsing machinery so that e.g. "clone --recurs ..."
doesn't error out because "clone" understands both "--recursive" and
"--recurse-submodules" to mean the same thing.
Initially "clone" just understood --recursive until the
--recurses-submodules alias was added in ccdd3da652 ("clone: Add the
--recurse-submodules option as alias for --recursive",
2010-11-04). Since bb62e0a99f ("clone: teach --recurse-submodules to
optionally take a pathspec", 2017-03-17) the longer form has been
promoted to the default.
But due to the way the options parsing machinery works this resulted
in the rather absurd situation of:
$ git clone --recurs [...]
error: ambiguous option: recurs (could be --recursive or --recurse-submodules)
Add OPT_ALIAS() to express this link between two or more options and use
it in git-clone. Multiple aliases of an option could be written as
OPT_ALIAS(0, "alias1", "original-name"),
OPT_ALIAS(0, "alias2", "original-name"),
...
The current implementation is not exactly optimal in this case. But we
can optimize it when it becomes a problem. So far we don't even have two
aliases of any option.

However, in the version that the protocol v2 patches made it into core

spawning `git serve`; The only reason in life for `git serve` to survive
