In many projects the number of contributors is low enough that users know
each other and the full email address doesn't need to be displayed.
Displaying only the author's username saves a lot of columns on the screen.
Existing 'e/E' (as in "%ae" and "%aE") placeholders would show the
author's address as "prarit@redhat.com", which would waste columns to show
the same domain-part for all contributors when used in a project internal
to redhat. Introduce 'l/L' placeholders that strip '@' and domain part from

Ever since worktrees were introduced, the `git_path()` function _really_
needed to be called e.g. to get at the path to `logs/HEAD` (`HEAD` is
specific to the worktree, and therefore so is its reflog). However, the
wrong path is returned for `logs/HEAD.lock`.
This does not matter as long as the Git executable is doing the asking,
as the path for that `logs/HEAD.lock` file is constructed from
`git_path("logs/HEAD")` by appending the `.lock` suffix.
However, Git GUI just learned to use `--git-path` instead of appending
relative paths to what `git rev-parse --git-dir` returns (and as a
consequence not only using the correct hooks directory, but also using
the correct paths in worktrees other than the main one). While it does
not seem as if Git GUI in particular is asking for `logs/HEAD.lock`,
let's be safe rather than sorry.
Side note: Git GUI _does_ ask for `index.lock`, but that is already
resolved correctly, due to `update_common_dir()` preferring to leave
unknown paths in the (worktree-specific) git directory.

The indent heuristic is our default diff heuristic since 33de716387
(diff: enable indent heuristic by default, 2017-05-08), but the usage
string of 'git blame' still mentions it as "experimental heuristic".
We could simply update the short help associated with the option, but
according to the comment above the option's declaration it was "only
included here to get included in the "-h" output". That made sense
while the feature was still experimental and we wanted to give it more
exposure, but nowadays it's unnecessary.
So let's rather remove the '--indent-heuristic' option from 'git
blame's usage string. Note that 'git blame' will still accept this
option, as it is parsed in parse_revision_opt().
Astute readers may notice that this patch removes a comment mentioning
"the following two options", but it only removes one option. The
reason is that the comment is outdated: that other options was
'--compaction-heuristic', and it has already been removed in

The hotfix application example uses `git merge --no-commit` to apply
temporary changes to the working tree during a bisect operation. In some
situations this can be a fast-forward and `merge` will apply the hotfix
branch's commits regardless of `--no-commit` (as documented in the `git
merge` manual).
In the pathological case this will make a `git bisect run` invocation
loop indefinitely between the first bisect step and the fast-forwarded
post-merge HEAD.
Add `--no-ff` to the merge command to avoid this issue.

Commit 90cf590f53 (fsck: optionally show more helpful info for broken
links, 2016-07-17) added a system for decorating objects with names. The
code is split across builtin/fsck.c (which gives the initial names) and
fsck.c (which adds to the names as it traverses the object graph). This
leads to some duplication, where both sites have near-identical
describe_object() functions (the difference being that the one in
builtin/fsck.c uses a circular array of buffers to allow multiple calls
in a single printf).
Let's provide a unified object_name API for fsck. That lets us drop the
duplication, as well as making the interface boundaries more clear
(which will let us refactor the implementation more in a future patch).
We'll leave describe_object() in builtin/fsck.c as a thin wrapper around
the new API, as it relies on a static global to make its many callers a
bit shorter.
We'll also convert the bare add_decoration() calls in builtin/fsck.c to
put_object_name(). This fixes two minor bugs:
1. We leak many small strings. add_decoration() has a last-one-wins
approach: it updates the decoration to the new string and returns
the old one. But we ignore the return value, leaking the old
string. This is quite common to trigger, since we look at reflogs:
the tip of any ref will be described both by looking at the actual
ref, as well as the latest reflog entry. So we'd always end up
leaking one of those strings.
2. The last-one-wins approach gives us lousy names. For instance, we
first look at all of the refs, and then all of the reflogs. So
rather than seeing "refs/heads/master", we're likely to overwrite
it with "HEAD@{12345678}". We're generally better off using the
first name we find.
And indeed, the test in t1450 expects this ugly HEAD@{} name. After
this patch, we've switched to using fsck_put_object_name()'s
first-one-wins semantics, and we output the more human-friendly
"refs/tags/julius" (and the test is updated accordingly).

The fsck_object() function takes in a buffer, but also a "struct
object". The rules for using these vary between types:
- for a commit, we'll use the provided buffer; if it's NULL, we'll
fall back to get_commit_buffer(), which loads from either an
in-memory cache or from disk. If the latter fails, we'd die(), which
is non-ideal for fsck.
- for a tag, a NULL buffer will fall back to loading the object from
disk (and failure would lead to an fsck error)
- for a tree, we _never_ look at the provided buffer, and always use
tree->buffer
- for a blob, we usually don't look at the buffer at all, unless it
has been marked as a .gitmodule file. In that case we check the
buffer given to us, or assume a NULL buffer is a very large blob
(and complain about it)
This is much more complex than it needs to be. It turns out that nobody
ever feeds a NULL buffer that isn't a blob:
- git-fsck calls fsck_object() only from fsck_obj(). That in turn is
called by one of:
- fsck_obj_buffer(), which is a callback to verify_pack(), which
unpacks everything except large blobs into a buffer (see
pack-check.c, lines 131-141).
- fsck_loose(), which hits a BUG() on non-blobs with a NULL buffer
(builtin/fsck.c, lines 639-640)
And in either case, we'll have just called parse_object_buffer()
anyway, which would segfault on a NULL buffer for commits or tags
(not for trees, but it would install a NULL tree->buffer which would
later cause a segfault)
- git-index-pack asserts that the buffer is non-NULL unless the object
is a blob (see builtin/index-pack.c, line 832)
- git-unpack-objects always writes a non-NULL buffer into its
obj_buffer hash, which is then fed to fsck_object(). (There is
actually a funny thing here where it does not store blob buffers at
all, nor does it call fsck on them; it does check any needed blobs
via fsck_finish() though).
Let's make the rules simpler, which reduces the amount of code and gives
us more flexibility in refactoring the fsck code. The new rules are:
- only blobs are allowed to pass a NULL buffer
- we always use the provided buffer, never pulling information from
the object struct
We don't have to adjust any callers, because they were already adhering
to these. Note that we do drop a few fsck identifiers for missing tags,
but that was all dead code (because nobody passed a NULL tag buffer).

Way back in 92d4c85d24 (fsck-cache: fix SIGSEGV on bad tag object,
2005-05-03), we added an fsck check that the "tagged" field of a tag
struct isn't NULL. But that was mainly protecting the printing code for
"--tags", and that code wasn't moved along with the check as part of
ba002f3b28 (builtin-fsck: move common object checking code to fsck.c,
2008-02-25).
It could also serve to detect type mismatch problems (where a tag points
to object X as a commit, but really X is a blob), but it couldn't do so
reliably (we'd call lookup_commit(X), but it will only notice the
problem if we happen to have previously called lookup_blob(X) in the
same process). And as of a commit earlier in this series, we'd consider
that a parse error and complain about the object even before getting to
this point anyway.
So let's drop this "tag->tagged" check. It's not helping anything, and
getting rid of it makes the function conceptually cleaner, as it really
is just checking the buffer we feed it. In fact, we can get rid of our
one-line wrapper and just unify fsck_tag() and fsck_tag_buffer().

In 4516338243 (builtin-fsck: reports missing parent commits,
2008-02-25), we added code to check that fsck found the same number of
parents from parsing the commit itself as we see in the commit struct we
got from parse_commit_buffer(). Back then the rationale was that the
normal commit parser might skip some bad parents.
But earlier in this series, we started treating that reliably as a
parsing error, meaning that we'd complain about it before we even hit
the code in fsck.c.
Let's drop this code, which now makes fsck_commit_buffer() completely
independent of any parsed values in the commit struct (that's
conceptually cleaner, and also opens up more refactoring options).
Note that we can also drop the MISSING_PARENT and MISSING_GRAFT fsck
identifiers. This is no loss, as these would not trigger reliably
anyway. We'd hit them only when lookup_commit() failed, which occurs
only if we happen to have seen the object with another type already in
the same process. In most cases, we'd actually run into the problem
during the connectivity walk, not here.

We check in fsck_commit_buffer() that commit->tree isn't NULL, which in
turn generally comes from a previous parse by parse_commit(). But this
isn't really accomplishing anything. The two things we might care about
are:
- was there a syntactically valid "tree <oid>" line in the object? But
we've just done our own parse in fsck_commit_buffer() to check this.
- does it point to a valid tree object? But checking the "tree"
pointer here doesn't actually accomplish that; it just shows that
lookup_tree() didn't return NULL, which only means that we haven't
yet seen that oid as a non-tree in this process.
A real connectivity check would exhaustively walk all graph links,
and we do that already in a separate function.
So this code isn't helping anything. And it makes the fsck code slightly
more confusing and rigid (e.g., it requires that any commit structs have
already been parsed). Let's drop it.
As a bit of history, the presence of this code looks like a leftover
from early fsck code (which did rely on parse_commit() to do most of the
parsing). The check comes from ff5ebe39b0 (Port fsck-cache to use
parsing functions, 2005-04-18), but we later added an explicit walk in
355885d531 (add generic, type aware object chain walker, 2008-02-25).

If we can't parse a commit, then parse_commit() will return an error
code. But it _also_ sets the "parsed" flag, which tells us not to bother
trying to re-parse the object. That means that subsequent parses have no
idea that the information in the struct may be bogus. I.e., doing this:
parse_commit(commit);
...
if (parse_commit(commit) < 0)
die("commit is broken");
will never trigger the die(). The second parse_commit() will see the
"parsed" flag and quietly return success.
There are two obvious ways to fix this:
1. Stop setting "parsed" until we've successfully parsed.
2. Keep a second "corrupt" flag to indicate that we saw an error (and
when the parsed flag is set, return 0/-1 depending on the corrupt
flag).
This patch does option 1. The obvious downside versus option 2 is that
we might continually re-parse a broken object. But in practice,
corruption like this is rare, and we typically die() or return an error
in the caller. So it's OK not to worry about optimizing for corruption.
And it's much simpler: we don't need to use an extra bit in the object
struct, and callers which check the "parsed" flag don't need to learn
about the corrupt bit, too.
There's no new test here, because this case is already covered in t5318.
Note that we do need to update the expected message there, because we
now detect the problem in the return from "parse_commit()", and not with
a separate check for a NULL tree. In fact, we can now ditch that
explicit tree check entirely, as we're covered robustly by this change
(and the previous recent change to treat a NULL tree as a parse error).
We'll also give tags the same treatment. I don't know offhand of any
cases where the problem can be triggered (it implies somebody ignoring a
parse error earlier in the process), but consistently returning an error
should cause the least surprise.
