docs: explain how to deal with files that are always modified
Users frequently have problems where two filenames differ only in case,
causing one of those files to show up consistently as being modified.
Let's add a FAQ entry that explains how to deal with that.
In addition, let's explain another common case where files are
consistently modified, which is when files using a smudge or clean
filter have not been run through that filter. Explain the way to fix

docs: explain why reverts are not always applied on merge
A common scenario is for a user to apply a change to one branch and
cherry-pick it into another, then later revert it in the first branch.
This results in the change being present when the two branches are
merged, which is confusing to many users.
We already have documentation for how this works in `git merge`, but it
is clear from the frequency with which this is asked that it's hard to
grasp. We also don't explain to users that they are better off doing a
rebase in this case, which will do what they intended. Let's add an

docs: explain why squash merges are broken with long-running branches
In many projects, squash merges are commonly used, primarily to keep a
tidy history in the face of developers who do not use logically
independent, bisectable commits. As common as this is, this tends to

long-running branches due to the lack of any new merge bases. Even very

wt-status: tolerate dangling marks
When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to

xrealloc: do not reuse pointer freed by zero-length realloc()
This patch fixes a bug where xrealloc(ptr, 0) can double-free and
corrupt the heap on some platforms (including at least glibc).
The C99 standard says of malloc (section 7.20.3):
If the size of the space requested is zero, the behavior is
implementation-defined: either a null pointer is returned, or the
behavior is as if the size were some nonzero value, except that the
returned pointer shall not be used to access an object.
So we might get NULL back, or we might get an actual pointer (but we're
not allowed to look at its contents). To simplify our code, our
xmalloc() handles a NULL return by converting it into a single-byte
allocation. That way callers get consistent behavior. This was done way
back in
4e7a2eccc2 (?alloc: do not return NULL when asked for zero
bytes, 2005-12-29).
We also gave xcalloc() and xrealloc() the same treatment. And according
to C99, that is fine; the text above is in a paragraph that applies to
all three. But what happens to the memory we passed to realloc() in such
a case? I.e., if we do:
ret = realloc(ptr, 0);
and "ptr" is non-NULL, but we get NULL back, is "ptr" still valid? C99
doesn't cover this case specifically, but says (section 7.20.3.4):
The realloc function deallocates the old object pointed to by ptr and
returns a pointer to a new object that has the size specified by size.
So "ptr" is now deallocated, and we must only look at "ret". And since
"ret" is NULL, that means we have no allocated object at all. But that's
not quite the whole story. It also says:
If memory for the new object cannot be allocated, the old object is
not deallocated and its value is unchanged.
[...]
The realloc function returns a pointer to the new object (which may
have the same value as a pointer to the old object), or a null pointer
if the new object could not be allocated.
So if we see a NULL return with a non-zero size, we can expect that the
original object _is_ still valid. But with a non-zero size, it's
ambiguous. The NULL return might mean a failure (in which case the
object is valid), or it might mean that we successfully allocated
nothing, and used NULL to represent that.
The glibc manpage for realloc() explicitly says:
[...]if size is equal to zero, and ptr is not NULL, then the call is
equivalent to free(ptr).
Likewise, this StackOverflow answer:
https://stackoverflow.com/a/
2135302
claims that C89 gave similar guidance (but I don't have a copy to verify
it). A comment on this answer:
https://stackoverflow.com/a/
2022410
claims that Microsoft's CRT behaves the same.
But our current "retry with 1 byte" code passes the original pointer
again. So on glibc, we effectively free() the pointer and then try to
realloc() it again, which is undefined behavior.
The simplest fix here is to just pass "ret" (which we know to be NULL)
to the follow-up realloc(). But that means that a system which _doesn't_
free the original pointer would leak it. It's not clear if any such
systems exist, and that interpretation of the standard seems unlikely
(I'd expect a system that doesn't deallocate to simply return the
original pointer in this case). But it's easy enough to err on the safe
side, and just never pass a zero size to realloc() at all.

init: make --separate-git-dir work from within linked worktree
The intention of `git init --separate-work-dir=<path>` is to move the
.git/ directory to a location outside of the main worktree. When used
within a linked worktree, however, rather than moving the .git/
directory as intended, it instead incorrectly moves the worktree's
.git/worktrees/<id> directory to <path>, thus disconnecting the linked
worktree from its parent repository and breaking the worktree in the
process since its local .git file no longer points at a location at
which it can find the object database. Fix this broken behavior.
An intentional side-effect of this change is that it also closes a
loophole not caught by
ccf236a23a (init: disallow --separate-git-dir

midx: traverse the local MIDX first
When a repository has an alternate object directory configured, callers
can traverse through each alternate's MIDX by walking the '->next'
pointer.
But, when 'prepare_multi_pack_index_one()' loads multiple MIDXs, it
places the new ones at the front of this pointer chain, not at the end.
This can be confusing for callers such as 'git repack -ad', causing test
failures like in t7700.6 with 'GIT_TEST_MULTI_PACK_INDEX=1'.
The occurs when dropping a pack known to the local MIDX with alternates
configured that have their own MIDX. Since the alternate's MIDX is
returned via 'get_multi_pack_index()', 'midx_contains_pack()' returns
true (which is correct, since it traverses through the '->next' pointer
to find the MIDX in the chain that does contain the requested object).
But, we call 'clear_midx_file()' on 'the_repository', which drops the
MIDX at the path of the first MIDX in the chain, which (in the case of
t7700.6 is the one in the alternate).
This patch addresses that by:
- placing the local MIDX first in the chain when calling
'prepare_multi_pack_index_one()', and
- introducing a new 'get_local_multi_pack_index()', which explicitly
returns the repository-local MIDX, if any.
Don't impose an additional order on the MIDX's '->next' pointer beyond
that the first item in the chain must be local if one exists so that we
avoid a quadratic insertion.
Likewise, use 'get_local_multi_pack_index()' in
'remove_redundant_pack()' to fix the formerly broken t7700.6 when run
with 'GIT_TEST_MULTI_PACK_INDEX=1'.
Finally, note that the MIDX ordering invariant is only preserved by the
insertion order in 'prepare_packed_git()', which traverses through the
ODB's '->next' pointer, meaning we visit the local object store first.
This fragility makes this an undesirable long-term solution if more
callers are added, but it is acceptable for now since this is the only
caller.

the former isn't called in case of non-existent submodule directory,
consequently, there is no such error message on any execution

worktree: fix leak in check_clean_worktree()
We allocate a child_env strvec but never free its memory. Instead, let's

And while we're moving the initialization of the child_process around,

builtin/repack.c: invalidate MIDX only when necessary
In
525e18c04b (midx: clear midx on repack, 2018-07-12), 'git repack'
learned to remove a multi-pack-index file if it added or removed a pack
from the object store.
This mechanism is a little over-eager, since it is only necessary to
drop a MIDX if 'git repack' removes a pack that the MIDX references.
Adding a pack outside of the MIDX does not require invalidating the
MIDX, and likewise for removing a pack the MIDX does not know about.
Teach 'git repack' to check for this by loading the MIDX, and checking
whether the to-be-removed pack is known to the MIDX. This requires a
slightly odd alternation to a test in t5319, which is explained with a
comment. A new test is added to show that the MIDX is left alone when
both packs known to it are marked as .keep, but two packs unknown to it
are removed and combined into one new pack.

revision: set rev_input_given in handle_revision_arg()
Commit
7ba826290a (revision: add rev_input_given flag, 2017-08-02) added
a flag to rev_info to tell whether we got any revision arguments. As
explained there, this is necessary because some revision arguments may
not produce any pending traversal objects, but should still inhibit
default behaviors (e.g., a glob that matches nothing).
However, it only set the flag in the globbing code, but not for
revisions we get on the command-line or via stdin. This leads to two
problems:
- the command-line code keeps its own separate got_rev_arg flag; this
isn't wrong, but it's confusing and an extra maintenance burden
- even specifically-named rev arguments might end up not adding any
pending objects: if --ignore-missing is set, then specifying a
missing object is a noop rather than an error.
And that leads to some user-visible bugs:
- when deciding whether a default rev like "HEAD" should kick in, we
check both got_rev_arg and rev_input_given. That means that
"--ignore-missing $ZERO_OID" works on the command-line (where we set
got_rev_arg) but not on --stdin (where we don't)
- when rev-list decides whether it should complain that it wasn't
given a starting point, it relies on rev_input_given. So it can't
even get the command-line "--ignore-missing $ZERO_OID" right
Let's consistently set the flag if we got any revision argument. That
lets us clean up the redundant got_rev_arg, and fixes both of those bugs
(but note there are three new tests: we'll confirm the already working
git-log command-line case).
A few implementation notes:
- conceptually we want to set the flag whenever handle_revision_arg()
finds an actual revision arg ("handles" it, you might say). But it
covers a ton of cases with early returns. Rather than annotating
each one, we just wrap it and use its success exit-code to set the
flag in one spot.
- the new rev-list test is in t6018, which is titled to cover globs.
This isn't exactly a glob, but it made sense to stick it with the
other tests that handle the "even though we got a rev, we have no
pending objects" case, which are globs.
- the tests check for the oid of a missing object, which it's pretty
clear --ignore-missing should ignore. You can see the same behavior
with "--ignore-missing a-ref-that-does-not-exist", because
--ignore-missing treats them both the same. That's perhaps less
clearly correct, and we may want to change that in the future. But
the way the code and tests here are written, we'd continue to do the
right thing even if it does.

refs: remove lookup cache for reference-transaction hook
When adding the reference-transaction hook, there were concerns about
the performance impact it may have on setups which do not make use of
the new hook at all. After all, it gets executed every time a reftx is
prepared, committed or aborted, which linearly scales with the number of
reference-transactions created per session. And as there are code paths
like `git push` which create a new transaction for each reference to be
updated, this may translate to calling `find_hook()` quite a lot.
To address this concern, a cache was added with the intention to not
repeatedly do negative hook lookups. Turns out this cache caused a
regression, which was fixed via
e5256c82e5 (refs: fix interleaving hook
calls with reference-transaction hook, 2020-08-07). In the process of
discussing the fix, we realized that the cache doesn't really help even
in the negative-lookup case. While performance tests added to benchmark
this did show a slight improvement in the 1% range, this really doesn't
warrent having a cache. Furthermore, it's quite flaky, too. E.g. running
it twice in succession produces the following results:
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.2: update-ref 2.79(2.16+0.74) 2.73(2.12+0.71) -2.2%
1400.3: update-ref --stdin 0.22(0.08+0.14) 0.21(0.08+0.12) -4.5%
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.2: update-ref 2.70(2.09+0.72) 2.74(2.13+0.71) +1.5%
1400.3: update-ref --stdin 0.21(0.10+0.10) 0.21(0.08+0.13) +0.0%
One case notably absent from those benchmarks is a single executable
searching for the hook hundreds of times, which is exactly the case for
which the negative cache was added. p1400.2 will spawn a new update-ref
for each transaction and p1400.3 only has a single reference-transaction
for all reference updates. So this commit adds a third benchmark, which
performs an non-atomic push of a thousand references. This will create a
new reference transaction per reference. But even for this case, the
negative cache doesn't consistently improve performance:
Test master pks-reftx-hook-remove-cache
--------------------------------------------------------------------------
1400.4: nonatomic push 6.63(6.50+0.13) 6.81(6.67+0.14) +2.7%
1400.4: nonatomic push 6.35(6.21+0.14) 6.39(6.23+0.16) +0.6%
1400.4: nonatomic push 6.43(6.31+0.13) 6.42(6.28+0.15) -0.2%
So let's just remove the cache altogether to simplify the code.
