get_oid(): when an object was not found, try harder
It is quite possible that the loose object cache gets stale when new
objects are written. In that case, get_oid() would potentially say that
it cannot find a given object, even if it should find it.
Let's blow away the loose object cache as well as the read packs and try
again in that case.
Note: this does *not* affect the code path that was introduced to help
avoid looking for the same non-existing objects (which made some
operations really expensive via NFS): that code path is handled by the
`OBJECT_INFO_QUICK` flag (which does not even apply to `get_oid()`,
which has no equivalent flag, at least at the time this patch was
written).
This incidentally fixes the problem identified earlier where an
interactive rebase wanted to re-read (and validate) the todo list after
an `exec` command modified it.

rebase -i: demonstrate obscure loose object cache bug
We specifically support `exec` commands in `git rebase -i`'s todo lists
to rewrite the very same todo list. Of course, we need to validate that
todo list when re-reading it.
It is also totally legitimate to extend the todo list by `pick` lines
using short names of commits that were created only after the rebase
started.
And this is where the loose object cache interferes with this feature:
if *some* loose object was read whose hash shares the same first two
digits with a commit that was not yet created when that loose object was
created, then we fail to find that new commit by its short name in
`get_oid()`, and the interactive rebase fails with an obscure error
message like:
error: invalid line 1: pick 6568fef
error: please fix this using 'git rebase --edit-todo'.
Let's first demonstrate that this is actually a bug in a new regression
test, in a separate commit so that other developers who do not believe
me can cherry-pick it to confirm the problem.
This new regression test generates two commits whose hashes share the
first two hex digits (so that their corresponding loose objects live in
the same subdirectory of .git/objects/, and are therefore supposed to be
in the same loose object cache bin).
It then picks the first, to make sure that the loose object cache is
initialized and cached that object directory, then generates the second
commit and picks it, too. Since the commit was generated in a different
process than the sequencer that wants to pick it, the loose object cache
had no chance of being updated in the meantime.
Technically, we would need only one `exec` command in this regression
test case, but for ease of implementation, it uses a pseudo-recursive
call to the same script.

When cloning with --recurse-submodules a superproject with at least one
submodule with HEAD pointing to an unborn branch, the clone goes
something like this:
Cloning into 'test'...
<messages about cloning of superproject>
Submodule '<name>' (<uri>) registered for path '<submodule path>'
Cloning into '<submodule path>'...
fatal: Couldn't find remote ref HEAD
Unable to fetch in submodule path '<submodule path>'
<messages about fetching with SHA-1>
From <uri>
* branch <hash> -> FETCH_HEAD
Submodule path '<submodule path>': checked out '<hash>'
In other words, first, a fetch is done with no hash arguments (that is,
a fetch of HEAD) resulting in a "Couldn't find remote ref HEAD" error;
then, a fetch is done given a hash, which succeeds.
The fetch given a hash was added in fb43e31f2b ("submodule: try harder
to fetch needed sha1 by direct fetching sha1", 2016-02-24), and the
"Unable to fetch..." message was downgraded from a fatal error to a
notice in e30d833671 ("git-submodule.sh: try harder to fetch a
submodule", 2018-05-16).
This commit improves the notice to be clearer that we are retrying the
fetch, and that the previous messages (in particular, the fatal errors
from fetch) do not necessarily indicate that the whole command fails. In
other words:
- If the HEAD-fetch succeeds and we then have the commit we want,
git-submodule prints no explanation.
- If the HEAD-fetch succeeds and we do not have the commit we want, but
the hash-fetch succeeds, git-submodule prints no explanation.
- If the HEAD-fetch succeeds and we do not have the commit we want, but
the hash-fetch fails, git-submodule prints a fatal error.
- If the HEAD-fetch fails, fetch prints a fatal error, and
git-submodule informs the user that it will retry by fetching
specific commits by hash.
- If the hash-fetch then succeeds, git-submodule prints no
explanation (besides the ones already printed).
- If the HEAD-fetch then fails, git-submodule prints a fatal error.
It could be said that we should just eliminate the HEAD-fetch
altogether, but that changes some behavior (in particular, some refs
that were opportunistically updated would no longer be), so I have left
that alone for now.
There is an analogous situation with the fetching code in fetch_finish()
and surrounding functions. For now, I have added a NEEDSWORK.

Makefile: fix unaligned loads in sha1dc with UBSan
The sha1dc library uses unaligned loads on platforms that support them.
This is normally what you'd want for performance, but it does cause
UBSan to complain when we compile with SANITIZE=undefined. Just like we

The current documentation uses both quotes (italics) and backquotes
(monospace) to render URLs and pathnames, which is inconsistent.
Document a best practice in CodingGuidelines to help reduce
inconsistencies in the future.
We set the best practice to using backquotes, since:
* It is already an established practice. For exemple:
$ git grep "'[^']/*[^']'" | wc -l
206
$ git grep '`[^`]/*[^`]`' | wc -l
690
There are false positives on both sides, but after a cursory look at
the output of both, it doesn't seem the false positive rate is really
higher in the second case.
At least, this shows that the existing documentation uses
inconsistent formatting, and that it would be good to do
something about it.
* It may be debatable whether path names need to be typed in
monospace but having them in italics is really unusual.

In the contributing guide and PR template seen by people who open pull
requests on GitHub, we mention the submitGit tool, which gives an
alternative to figuring out the mailing list. These days we also have
the similar GitGitGadget tool, and we should make it clear that this
is also an option.
We could continue to mention _both_ tools, but it's probably better to
pick one in order to avoid overwhelming the user with choice. After all,
one of the purposes here is to reduce friction for first-time or
infrequent contributors. And there are a few reasons to prefer GGG:
1. submitGit seems to still have a few rough edges. E.g., it doesn't
munge timestamps to help threaded mail readers handled out-of-order
delivery.
2. Subjectively, GGG seems to be more commonly used on the list these
days, especially by list regulars.
3. GGG seems to be under more active development (likely related to
point 2).
So let's actually swap out submitGit for GGG. While we're there, let's
put another link to the GGG page in the PR template, because that's
where users who are learning about it for the first time will want to go
to read more.

mingw: respect core.hidedotfiles = false in git-init again
This is a brown paper bag. When adding the tests, we actually failed
to verify that the config variable is heeded in git-init at all. And
when changing the original patch that marked the .git/ directory as
hidden after reading the config, it was lost on this developer that
the new code would use the hide_dotfiles variable before the config
was read.
The fix is obvious: read the (limited, pre-init) config *before*
creating the .git/ directory.
Please note that we cannot remove the identical-looking `git_config()`
call from `create_default_files()`: we create the `.git/` directory
between those calls. If we removed it, and if the parent directory is
in a Git worktree, and if that worktree's `.git/config` contained any
`init.templatedir` setting, we would all of a sudden pick that up.

asciidoctor-extensions: fix spurious space after linkgit
When we render, e.g., "linkgit:gitglossary[7]." with Asciidoctor, we get
"gitglossary(7) ." with a space between the linkgit macro expansion and
the punctuation. We can fix this by dropping the trailing newline after
we've turned `linkgit:foo[bar]` into `<citerefentry>..</citerefentry>`.
The diff produced by `USE_ASCIIDOCTOR=Yes ./doc-diff HEAD^ HEAD` is
almost 6000 lines large and shows how this fixes "git-foo(x) ,", "(see
git-bar(y) )" and so on. One might wonder whether this also turns, e.g.,
"see linkgit:foo[1] for more" into "see foo(1)for more", but no. We get
"...</citerefentry> for more" in the XML, see, e.g., git-am.xml, so the
space ends up in git-am.1 just fine. The same is true for the HTML output.

Recently the Git for Windows project started the upgrade process to
a MSYS2 runtime version based on Cygwin v3.x.
This has the very notable consequence that `$(uname -r)` no longer
reports a version starting with "2", but a version with "3".
That breaks our build, as df5218b4c30b (config.mak.uname: support MSys2,
2016-01-13) simply did not expect the version reported by `uname -r` to
depend on the underlying Cygwin version: it expected the reported
version to match the "2" in "MSYS2".
So let's invert that test case to test for *anything else* than a
version starting with "1" (for MSys). That should safeguard us for the

a9be29c981 (sequencer: make refs generated by the `label` command
worktree-local, 2018-04-25) adds refs/rewritten/ as per-worktree
reference space. Unfortunately (my bad) there are a couple places that
need update to make sure it's really per-worktree.
- add_per_worktree_entries_to_dir() is updated to make sure ref listing
look at per-worktree refs/rewritten/ instead of per-repo one [1]
- common_list[] is updated so that git_path() returns the correct
location. This includes "rev-parse --git-path".
This mess is created by me. I started trying to fix it with the
introduction of refs/worktree, where all refs will be per-worktree
without special treatments. Unfortunate refs/rewritten came before
refs/worktree so this is all we can do.
This also fixes logs/refs/worktree not being per-worktree.
[1] note that ref listing still works sometimes. For example, if you
have .git/worktrees/foo/refs/rewritten/bar AND the directory
.git/worktrees/refs/rewritten, refs/rewritten/bar will show up.
add_per_worktree_entries_to_dir() is only needed when the directory
.git/worktrees/refs/rewritten is missing.

We write the output of a "clean" filter into a strbuf. Rather than
growing the strbuf dynamically as we read its output, we make the
initial allocation as large as the original input file. This is a good
guess when the filter is just tweaking a few bytes, but it's disastrous
when the point of the filter is to condense a very large file into a
short identifier (e.g., the way git-lfs and git-annex do). We may ask to
allocate many gigabytes, causing the allocation to fail and Git to
die().
Instead, let's just let strbuf do its usual growth.
When the clean filter does output something around the same size as the
worktree file, the buffer will need to be reallocated until it fits,
starting at 8192 and doubling in size. Benchmarking indicates that
reallocation is not a significant overhead for outputs up to a

because a set of patches [1] that unifies the handling of SSH options,

the functionality in here is no longer needed.
As of this patch, all tests pass if GIT_TEST_PROTOCOL_VERSION is set to
1.
Define a GIT_TEST_PROTOCOL_VERSION environment variable meant to be used
from tests. When set, this ensures protocol.version is at least the
given value, allowing the entire test suite to be run as if this
configuration is in place for all repositories.
As of this patch, all tests pass whether GIT_TEST_PROTOCOL_VERSION is
unset or set to 0. Some tests fail when GIT_TEST_PROTOCOL_VERSION is set

tests: add a special setup where stash.useBuiltin is off
Add a GIT_TEST_STASH_USE_BUILTIN=false test mode which is equivalent
to running with stash.useBuiltin=false. This is needed to spot that
we're not introducing any regressions in the legacy stash version
while we're carrying both it and the new built-in version.
This imitates the equivalent treatment for the built-in rebase in 62c23938fae5 (tests: add a special setup where rebase.useBuiltin is off,
2018-11-14).

We recently converted the `git stash` command from Unix shell scripts
to builtins.
Let's end users a way out when they discover a bug in the
builtin command: `stash.useBuiltin`.
As the file name `git-stash` is already in use, let's rename the
scripted backend to `git-legacy-stash`.
To make the test suite pass with `stash.useBuiltin=false`, this commit
also backports rudimentary support for `-q` (but only *just* enough
to appease the test suite), and adds a super-ugly hack to force exit
code 129 for `git stash -h`.

stash: add back the original, scripted `git stash`
This simply copies the version as of sd/stash-wo-user-name verbatim. As
of now, it is not hooked up.
The next commit will change the builtin `stash` to hand off to the
scripted `git stash` when `stash.useBuiltin=false`.

The old shell script `git-stash.sh` was removed and replaced
entirely by `builtin/stash.c`. In order to do that, `create` and
`push` were adapted to work without `stash.sh`. For example, before
this commit, `git stash create` called `git stash--helper create
--message "$*"`. If it called `git stash--helper create "$@"`, then
some of these changes wouldn't have been necessary.
This commit also removes the word `helper` since now stash is
called directly and not by a shell script.

stash: optimize `get_untracked_files()` and `check_changes()`
This commits introduces a optimization by avoiding calling the
same functions again. For example, `git stash push -u`
would call at some points the following functions:
* `check_changes()` (inside `do_push_stash()`)
* `do_create_stash()`, which calls: `check_changes()` and
`get_untracked_files()`
Note that `check_changes()` also calls `get_untracked_files()`.
So, `check_changes()` is called 2 times and `get_untracked_files()`
3 times.
The old function `check_changes()` now consists of two functions:
`get_untracked_files()` and `check_changes_tracked_files()`.
These are the call chains for `push` and `create`:
To prevent calling the same functions over and over again,
`check_changes()` inside `do_create_stash()` is now placed
in the caller functions (`create_stash()` and `do_push_stash()`).
This way `check_changes()` and `get_untracked files()` are called
only one time.

There is a change in behaviour with this commit. When there was
no initial commit, the shell version of stash would still display
a message. This commit makes `push` to not display any message if
`--quiet` or `-q` is specified. Add tests for `--quiet`.

Add the drop and clear commands to the builtin helper. These two
are each simple, but are being added together as they are quite
related.
We have to unfortunately keep the drop and clear functions in the
shell script as functions are called with parameters internally
that are not valid when the commands are called externally. Once
pop is converted they can both be removed.

Add a builtin helper for performing stash commands. Converting
all at once proved hard to review, so starting with just apply
lets conversion get started without the other commands being
finished.
The helper is being implemented as a drop in replacement for
stash so that when it is complete it can simply be renamed and
the shell script deleted.
Delete the contents of the apply_stash shell function and replace
it with a call to stash--helper apply until pop is also
converted.
