Support for grafts predates Git's strbuf, and hence it is understandable
that there was a hard-coded line length limit of 1023 characters (which
was chosen a bit awkwardly, given that it is *exactly* one byte short of
aligning with the 41 bytes occupied by a commit name and the following
space or new-line character).
While regular commit histories hardly win comprehensibility in general
if they merge more than twenty-two branches in one go, it is not Git's
business to limit grafts in such a way.
In this particular developer's case, the use case that requires
substantially longer graft lines to be supported is the visualization of
the commits' order implied by their changes: commits are considered to
have an implicit relationship iff exchanging them in an interactive
rebase would result in merge conflicts.
Thusly implied branches tend to be very shallow in general, and the
resulting thicket of implied branches is usually very wide; It is
actually quite common that *most* of the commits in a topic branch have
not even one implied parent, so that a final merge commit has about as
many implied parents as there are commits in said branch.

builtin_diff_b_f() needs a path, not pathspec. Other modes in diff
can deal with pathspec just fine. But because of the current
GUARD_PATHSPEC() location, other modes also reject :(glob) and
:(icase).
Move GUARD_PATHSPEC(), and the "path" assignment statement, which is
the reason of this GUARD_PATHSPEC(), inside builtin_diff_b_f().

If you ask for-each-ref to print each ref and its object,
like:
git for-each-ref --format='%(objectname) %(refname)'
this should involve little more work than looking at the ref
files (and packed-refs) themselves. However, for-each-ref
will actually load each object from disk just to print its
sha1. For most repositories, this isn't a big deal, but it
can be noticeable if you have a large number of refs to
print. Here are best-of-five timings for the command above
on a repo with ~10K refs:
[before]
real 0m0.112s
user 0m0.092s
sys 0m0.016s
[after]
real 0m0.014s
user 0m0.012s
sys 0m0.000s
This patch checks for %(objectname) and %(objectname:short)
before we actually parse the object (and the rest of the
code is smart enough to avoid parsing if we have filled all
of our placeholders).
Note that we can't simply move the objectname parsing code
into the early loop. If the "deref" form %(*objectname) is
used, then we do need to parse the object in order to peel
the tag. So instead of moving the code, we factor it out
into a separate function that can be called for both cases.
While we're at it, we add some basic tests for the
dereferenced placeholders, which were not tested at all
before. This helps ensure we didn't regress that case.

Normally parse_pathspec() is used on command line arguments where it
can do fancy thing like parsing magic on each argument or adding magic
for all pathspecs based on --*-pathspecs options.
There's another use of parse_pathspec(), where pathspec is needed, but
the input is known to be pure paths. In this case we usually don't
want --*-pathspecs to interfere. And we definitely do not want to
parse magic in these paths, regardless of --literal-pathspecs.
Add new flag PATHSPEC_LITERAL_PATH for this purpose. When it's set,
--*-pathspecs are ignored, no magic is parsed. And if the caller
allows PATHSPEC_LITERAL (i.e. the next calls can take literal magic),
then PATHSPEC_LITERAL will be set.
This fixes cases where git chokes when GIT_*_PATHSPECS are set because
parse_pathspec() indicates it won't take any magic. But
GIT_*_PATHSPECS add them anyway. These are
export GIT_LITERAL_PATHSPECS=1
git blame -- something
git log --follow something
git log --merge
"git ls-files --with-tree=path" (aka parse_pathspec() in
overlay_tree_on_cache()) is safe because the input is empty, and
producing one pathspec due to PATHSPEC_PREFER_CWD does not take any
magic into account.

The add--interactive --patch mode adjusts the UI based on
whether we are pulling changes from HEAD or elsewhere (in
the former case it asks to unstage the reverse hunk, rather
than apply the forward hunk).
Commit 166ec2e taught reset to work on an unborn branch, but
in doing so, switched to always providing add--interactive
with the sha1 rather than the symbolic name. This meant we
always used the "apply" interface, even for "git reset -p
HEAD".
We can fix this by passing the symbolic name to
add--interactive. Since it understands unborn branches
these days, we do not even have to cover this special case
ourselves; we can simply pass HEAD.
The tests in t7105 now check that the right interface is
used in each circumstance (and notice the regression from
166ec2e we are fixing). The test in t7106 checks that we
get this right for the unborn case, too (not a regression,
since it didn't work at all before, but a nice improvement).

The said function has this signature:
extern int checkout_entry(struct cache_entry *ce,
const struct checkout *state,
char *topath);
At first glance, it might appear that the caller of checkout_entry()
can specify to which path the contents are written out by the last
parameter, and it is tempting to add "const" in front of its type.
In reality, however, topath[] is to point at a buffer to store the
temporary path generated by the callchain originating from this
function, and the temporary path is always short, much shorter than
the buffer prepared by its only caller in builtin/checkout-index.c.
Document the code a bit to clarify so that future callers know how
to use the function better.

The previous code was detecting the presence of "--" by looking only at
argument 1. As a result, "git checkout foo bar --" was interpreted as an
ambiguous file/revision list, and errored out with:
error: pathspec 'foo' did not match any file(s) known to git.
error: pathspec 'bar' did not match any file(s) known to git.
error: pathspec '--' did not match any file(s) known to git.
This patch fixes it by walking through the argument list to find the
"--", and now complains about the number of references given.

The "--" notation disambiguates files and branches, but as a side-effect
of the previous implementation, also disabled the branch auto-creation
when $branch does not exist.
A possible scenario is then:
git checkout $branch
=> fails if $branch is both a ref and a file, and suggests --
git checkout $branch --
=> refuses to create the $branch
This patch allows the second form to create $branch, and since the -- is
provided, it does not look for file named $branch.

This file isn't really harmful, but isn't useful either, and can create
minor annoyance for the user:
* It's confusing, as the presence of a *.pid file often implies that a
process is currently running. A user running "ls .git/" and finding
this file may incorrectly guess that a "git gc" is currently running.
* Leaving this file means that a "git gc" in an already gc-ed repo is
no-longer a no-op. A user running "git gc" in a set of repositories,
and then synchronizing this set (e.g. rsync -av, unison, ...) will see
all the gc.pid files as changed, which creates useless noise.
This patch unlinks the file after the garbage collection is done, so that
gc.pid is actually present only during execution.
Future versions of Git may want to use the information left in the gc.pid
file (e.g. for policies like "don't attempt to run a gc if one has
already been ran less than X hours ago"). If so, this patch can safely be
reverted. For now, let's not bother the users.

Correct all hits from
git grep -e '\(&&\|||\)[^ ]' -e '[^ ]\(&&\|||\)' -- '*.c'
i.e. && or || operators that are followed by anything but a SP,
or that follow something other than a SP or a HT, so that these
operators have a SP around it when necessary.
We usually refrain from making this kind of a tree-wide change in
order to avoid unnecessary conflicts with other "real work" patches,
but in this case, the end result does not have a potentially
cumbersome tree-wide impact, while this is a tree-wide cleanup.
Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a
HT immediately after && with a SP.
This is based on Felipe's patch to bultin/symbolic-ref.c; I did all
the finding out what other files in the whole tree need to be fixed
and did the fix and also the log message while reviewing that single
liner, so any screw-ups in this version are mine.

In commit 0656781fa "git mv" learned to update the submodule path in the
.gitmodules file when moving a submodule in the work tree. But since that
commit update_path_in_gitmodules() gets called no matter if we moved a
submodule or a regular file, which is wrong and leads to a bogus warning
when moving a regular file in a repo containing a .gitmodules file:
warning: Could not find section in .gitmodules where path=<filename>
Fix that by only calling update_path_in_gitmodules() when moving a
submodule. To achieve that, we introduce the special SUBMODULE_WITH_GITDIR
define to distinguish the cases where we also have to connect work tree
and git directory from those where we only need to update the .gitmodules
setting.
A test for submodules using a .git directory together with a .gitmodules
file has been added to t7001. Even though newer git versions will always
use a gitfile when cloning submodules, repositories cloned with older git
versions will still use this layout.

Currently, we only try converting argv[1] from "-" into "@{-1}". This
means we do not notice "-" when used together with an option. Worse,
when "git cherry-pick" is run with no options, we segfault. Fix this
by doing the substitution after we have checked that there is
something in argv to cherry-pick and know any remaining options are
meant for the revision-listing machinery.
This still does not handle "-" after the first non-cherry-pick option.
For example,
git cherry-pick foo~2 - bar~5
and
git cherry-pick --no-merges -
will still dump usage.
