git: add --no-optional-locks option
Some tools like IDEs or fancy editors may periodically run
commands like "git status" in the background to keep track
of the state of the repository. Some of these commands may
refresh the index and write out the result in an
opportunistic way: if they can get the index lock, then they
update the on-disk index with any updates they find. And if
not, then their in-core refresh is lost and just has to be
recomputed by the next caller.
But taking the index lock may conflict with other operations
in the repository. Especially ones that the user is doing
themselves, which _aren't_ opportunistic. In other words,
"git status" knows how to back off when somebody else is
holding the lock, but other commands don't know that status
would be happy to drop the lock if somebody else wanted it.
There are a couple possible solutions:
1. Have some kind of "pseudo-lock" that allows other
commands to tell status that they want the lock.
This is likely to be complicated and error-prone to
implement (and maybe even impossible with just
dotlocks to work from, as it requires some
inter-process communication).
2. Avoid background runs of commands like "git status"
that want to do opportunistic updates, preferring
instead plumbing like diff-files, etc.
This is awkward for a couple of reasons. One is that
"status --porcelain" reports a lot more about the
repository state than is available from individual
plumbing commands. And two is that we actually _do_
want to see the refreshed index. We just don't want to
take a lock or write out the result. Whereas commands
like diff-files expect us to refresh the index
separately and write it to disk so that they can depend
on the result. But that write is exactly what we're
trying to avoid.
3. Ask "status" not to lock or write the index.
This is easy to implement. The big downside is that any
work done in refreshing the index for such a call is
lost when the process exits. So a background process
may end up re-hashing a changed file multiple times
until the user runs a command that does an index
refresh themselves.
This patch implements the option 3. The idea (and the test)
is largely stolen from a Git for Windows patch by Johannes
Schindelin,
67e5ce7f63 (status: offer *not* to lock the
index and update it, 2016-08-12). The twist here is that
instead of making this an option to "git status", it becomes
a "git" option and matching environment variable.
The reason there is two-fold:
1. An environment variable is carried through to
sub-processes. And whether an invocation is a
background process or not should apply to the whole
process tree. So you could do "git --no-optional-locks
foo", and if "foo" is a script or alias that calls
"status", you'll still get the effect.
2. There may be other programs that want the same
treatment.
I've punted here on finding more callers to convert,
since "status" is the obvious one to call as a repeated
background job. But "git diff"'s opportunistic refresh
of the index may be a good candidate.
The test is taken from
67e5ce7f63, and it's worth repeating
Johannes's explanation:
Note that the regression test added in this commit does
not *really* verify that no index.lock file was written;
that test is not possible in a portable way. Instead, we
verify that .git/index is rewritten *only* when `git
status` is run without `--no-optional-locks`.

validate_headref: use get_oid_hex for detached HEADs
If a candidate HEAD isn't a symref, we check that it
contains a viable sha1. But in a post-sha1 world, we should
be checking whether it has any plausible object-id.
We can do that by switching to get_oid_hex().
Note that both before and after this patch, we only check
for a plausible object id at the start of the file, and then
call that good enough. We ignore any content _after_ the
hex, so a string like:
0123456789012345678901234567890123456789 foo
is accepted. Though we do put extra bytes like this into
some pseudorefs (e.g., FETCH_HEAD), we don't typically do so
with HEAD. We could tighten this up by using parse_oid_hex(),
like:
if (!parse_oid_hex(buffer, &oid, &end) &&
*end++ == '\n' && *end == '\0')
return 0;
But we're probably better to remain on the loose side. We're
just checking here for a plausible-looking repository
directory, so heuristics are acceptable (if we really want
to be meticulous, we should use the actual ref code to parse
HEAD).

validate_headref: NUL-terminate HEAD buffer
When we are checking to see if we have a git repo, we peek
into the HEAD file and see if it's a plausible symlink,
symref, or detached HEAD.
For the latter two, we read the contents with read_in_full(),
which means they aren't NUL-terminated. The symref check is
careful to respect the length we got, but the sha1 check
will happily parse up to 40 bytes, even if we read fewer.
E.g.,:
echo 1234 >.git/HEAD
git rev-parse
will parse 36 uninitialized bytes from our stack buffer.
This isn't a big deal in practice. Our buffer is 256 bytes,
so we know we'll never read outside of it. The worst case is
that the uninitialized bytes look like valid hex, and we
claim a bogus HEAD file is valid. The chances of this
happening randomly are quite slim, but let's be careful.
One option would be to check that "len == 41" before feeding
the buffer to get_sha1_hex(). But we'd like to eventually
prepare for a world with variable-length hashes. Let's
NUL-terminate as soon as we've read the buffer (we already
even leave a spare byte to do so!). That fixes this problem
without depending on the size of an object id.

avoid looking at errno for short read_in_full() returns
When a caller tries to read a particular set of bytes via
read_in_full(), there are three possible outcomes:
1. An error, in which case -1 is returned and errno is
set.
2. A short read, in which fewer bytes are returned and
errno is unspecified (we never saw a read error, so we
may have some random value from whatever syscall failed
last).
3. The full read completed successfully.
Many callers handle cases 1 and 2 together by just checking
the result against the requested size. If their combined
error path looks at errno (e.g., by calling die_errno), they
may report a nonsense value.
Let's fix these sites by having them distinguish between the

This is discussed further in

Each of these instances is actually fine in practice:
- in get-tar-commit-id, the HEADERSIZE macro expands to a
signed integer. If it were switched to an unsigned type
(e.g., a size_t), then it would be a bug.
- the other two callers check for a short read only after

practice, but we'd prefer to model "!=" as a general
rule.

Win32: simplify loading of DLL functions

doc: put literal block delimiter around table
The git-read-tree manpage has a table that is meant to
be shown with its spacing exactly as it is in the source. We
mark it as a "literal paragraph" by indenting each line by
at least one space. This renders OK with asciidoc for both
the HTML and manpage versions.
But there are two problems when we render it with
asciidoctor.
The first is that some lines mix tabs and spaces. Even if
asciidoctor is correctly configured for 8-space tabs, it
seems to handle this case differently, soaking up some of
the initial literal-paragraph spaces and mis-aligning the
table text.
The second problem is that the table uses blank lines to
group rows. But as blank lines separate paragraphs in
asciidoc, this actually means that each chunk of the table
is rendered in its own pre-formatted <div> block. This
happens even with vanilla asciidoc, but there's no visible
result because the literal paragraphs aren't styled in any
special way. But with asciidoctor (or at least the styles
used on git-scm.com), literal paragraphs are styled with a
different background. This breaks the table into a visually
distracting sequence of chunks.
We can fix both by adding a literal-paragraph block
delimiter. That turns the whole table into a single block
(for both implementations) and causes asciidoctor to render
the indentation as it is in the source.

object_array: add and use `object_array_pop()`
In a couple of places, we pop objects off an object array `foo` by
decreasing `foo.nr`. We access `foo.nr` in many places, but most if not
all other times we do so read-only, e.g., as we iterate over the array.
But when we change `foo.nr` behind the array's back, it feels a bit
nasty and looks like it might leak memory.
Leaks happen if the popped element has an allocated `name` or `path`.
At the moment, that is not the case. Still, 1) the object array might
gain more fields that want to be freed, 2) a code path where we pop
might start using names or paths, 3) one of these code paths might be
copied to somewhere where we do, and 4) using a dedicated function for
popping is conceptually cleaner.
Introduce and use `object_array_pop()` instead. Release memory in the
new function. Document that popping an object leaves the associated
elements in limbo.
The converted places were identified by grepping for "\.nr\>" and
looking for "--".
Make the new function return NULL on an empty array. This is consistent
with `pop_commit()` and allows the following:
while ((o = object_array_pop(&foo)) != NULL) {
// do something
}
But as noted above, we don't need to go out of our way to avoid reading
`foo.nr`. This is probably more readable:
while (foo.nr) {

}
The name of `object_array_pop()` does not quite align with
`add_object_array()`. That is unfortunate. On the other hand, it matches
`object_array_clear()`. Arguably it's `add_...` that is the odd one out,
since it reads like it's used to "add" an "object array". For that
reason, side with `object_array_clear()`.

object_array: use `object_array_clear()`, not `free()`
Instead of freeing `foo.objects` for an object array `foo` (sometimes
conditionally), call `object_array_clear(&foo)`. This means we don't
poke as much into the implementation, which is already a good thing, but
also that we release the individual entries as well, thereby fixing at
least one memory-leak (in diff-lib.c).
If someone is holding on to a pointer to an element's `name` or `path`,
that is now a dangling pointer, i.e., we'd be turning an unpleasant
situation into an outright bug. To the best of my understanding no such
long-term pointers are being taken.
The way we handle `study` in builting/reflog.c still looks like it might
leak. That will be addressed in the next commit.

leak_pending: use `object_array_clear()`, not `free()`
Setting `leak_pending = 1` tells `prepare_revision_walk()` not to
release the `pending` array, and makes that the caller's responsibility.
See
4a43d374f (revision: add leak_pending flag, 2011-10-01) and
353f5657a (bisect: use leak_pending flag, 2011-10-01).
Commit
1da1e07c8 (clean up name allocation in prepare_revision_walk,
2014-10-15) fixed a memory leak in `prepare_revision_walk()` by
switching from `free()` to `object_array_clear()`. However, where we use
the `leak_pending`-mechanism, we're still only calling `free()`.
Use `object_array_clear()` instead. Copy some helpful comments from
353f5657a to the other callers that we update to clarify the memory
responsibilities, and to highlight that the commits are not affected
when we clear the array -- it is indeed correct to both tidy up the
commit flags and clear the object array.
Document `leak_pending` in revision.h to help future users get this
right.

builtin/commit: fix memory leak in `prepare_index()`
Release `pathspec` and the string list `partial`.
When we clear the string list, make sure we do not free the `util`
pointers. That would result in double-freeing, since we set them up as
`item->util = item` in `list_paths()`.
Initialize the string list early, so that we can always release it. That
introduces some unnecessary overhead in various code paths, but means
there is one and only one way out of the function. If we ever accumulate
more things we need to free, it should be straightforward to do so.

branch: fix "copy" to never touch HEAD
When creating a new branch B by copying the branch A that happens to
be the current branch, it also updates HEAD to point at the new
branch. It probably was made this way because "git branch -c A B"
piggybacked its implementation on "git branch -m A B",
This does not match the usual expectation. If I were sitting on a
blue chair, and somebody comes and repaints it to red, I would
accept ending up sitting on a chair that is now red (I am also OK to
stand, instead, as there no longer is my favourite blue chair). But
if somebody creates a new red chair, modelling it after the blue
chair I am sitting on, I do not expect to be booted off of the blue
chair and ending up on sitting on the new red one.
Let's fix this before it hits 'next'. Those who want to create a
new branch and switch to it can do "git checkout B" after doing a
"git branch -c B", and if that operation is so useful and deserves a
short-hand way to do so, perhaps extend "git checkout -b B" to copy
configurations while creating the new branch B.
