There are two types of string_lists: those that own the
string memory, and those that don't. You can tell the
difference by the strdup_strings flag, and one should use
either STRING_LIST_INIT_DUP, or STRING_LIST_INIT_NODUP as an
initializer.
Historically, the normal all-zeros initialization has
corresponded to the NODUP case. Many sites use no
initializer at all, and that works as a shorthand for that
case. But for a reader of the code, it can be hard to
remember which is which. Let's be more explicit and actually
have each site declare which type it means to use.
This is a fairly mechanical conversion; I assumed each site
was correct as-is, and just switched them all to NODUP.

There's no need for these option variables to be static,
except that they are referenced by the options array itself,
which is static. But having all of this static is simply
unnecessary and confusing (and inconsistent with most other
commands, which either use a static global option list or a
true function-local one).
Note that in some cases we may need to actually initialize
the variables (since we cannot rely on BSS to do so). This
is a net improvement to readability, though, as we can use
the more verbose initializers for our string_lists.

The executable bit will not be detected (and therefore will not be

though the users may still wish to add files as executable for
compatibility with other users who _do_ have `core.filemode`
functionality. For example, Windows users adding shell scripts may
wish to add them as executable for compatibility with users on

Although this can be done with a plumbing command

This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.
Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible. "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.
This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.
"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing
tooling based around mailsplit.

We cannot have a 'struct lock_file' allocated on the stack, as lockfile.c
keeps a linked list of all created lock_file structures.
Also 'struct apply_state' users might later want the same 'struct lock_file'
instance to be reused by different series of calls to the apply api.
So let's add a 'struct lock_file *lock_file' pointer into 'struct apply_state'
and have the user of 'struct apply_state' allocate memory for the actual
'struct lock_file' instance.
Let's also add an argument to init_apply_state(), so that the caller can
easily supply a pointer to the allocated instance.

You can ask rev-list to use bitmaps to speed up an --objects
traversal, which should generally give you your answers much
faster.
Likewise, you can ask rev-list to limit such a traversal
with `-n`, in which case we'll show only a limited set of
commits (and only the tree and commit objects directly
reachable from those commits).
But if you do both together, the results are nonsensical. We
end up limiting any fallback traversal we do to _find_ the
bitmaps, but the actual set of objects we output will be
picked arbitrarily from the union of any bitmaps we do find,
and will involve the objects of many more commits.
It's possible that somebody might want this as a "show me
what you can, but limit the amount of work you do" flag.
But as with the prior commit clamping "--count", the results
are basically non-deterministic; you'll get the values from
some commits between `n` and the total number, and you can't
tell which.
And unlike the `--count` case, we can't easily generate the
"real" value from the bitmap values (you can't just walk
back `-n` commits and subtract out the reachable objects
from the boundary commits; the bitmaps for `X` record its
total reachability, so you don't know which objects are
directly from `X` itself, which from `X^`, and so on).
So let's just fallback to the non-bitmap code path in this
case, so we always give a sane answer.

If you ask rev-list for:
git rev-list --count --use-bitmap-index HEAD
we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.
But if you ask to limit the size of the traversal, like:
git rev-list --count --use-bitmap-index -n 100 HEAD
we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.
But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.
This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:
- your `-n` value, if we walked back and never found a
bitmap (or fewer if there weren't that many commits)
- the actual full count, if we found a bitmap root for
every path of our traversal with in the `-n` limit
- any number in between! We might have walked back and
found _some_ bitmaps, but then cut off the traversal
early with some commits not accounted for in the result.
So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.
The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.
I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

git-pull silently ignores the --verify-signatures option when
running --rebase, potentially leaving users in the belief that
the rebase operation would check for valid GPG signatures.
Implementing --verify-signatures for git-rebase was talked about,
but doubts for a valid workflow rose up. Since you usually merge
other's branches into your branch you might have an interest that
their side has a valid GPG signature.
Rebasing, on the other hand, is to rebuild your branch on top of
other's work, in order to push the result back, and it is too late
to reject their work even if you find their commits lack acceptable
signature.
Let's warn users that the --verify-signatures option is ignored
during "pull --rebase"; users do not wonder what would happen if
their commits lack acceptable signature that way.

Traditionally cat-file's batch-mode does not do any output
buffering. The reason is that a caller may have pipes
connected to its input and output, and would want to use
cat-file interactively, getting output immediately for each
input it sends.
This may involve a lot of small write() calls, which can be
slow. So we introduced --buffer to improve this, but we
can't turn it on by default, as it would break the
interactive case above.
However, when --batch-all-objects is used, we do not read
stdin at all. We generate the output ourselves as quickly as
possible, and then exit. In this case buffering is a strict
win, and it is simply a hassle for the user to have to
remember to specify --buffer.
This patch makes --buffer the default when --batch-all-objects
is used. Specifying "--buffer" manually is still OK, and you
can even override it with "--no-buffer" if you're a
masochist (or debugging).
For some real numbers, running:
git cat-file --batch-all-objects --batch-check='%(objectname)'
on torvalds/linux goes from:
real 0m1.464s
user 0m1.208s
sys 0m0.252s
to:
real 0m1.230s
user 0m1.172s
sys 0m0.056s
for a 16% speedup.

It is not unreasonable to ask cat-file for a batch-check
format of simply "%(objectname)". At first glance this seems
like a noop (you are generally already feeding the object
names on stdin!), but it has a few uses:
1. With --batch-all-objects, you can generate a listing of
the sha1s present in the repository, without any input.
2. You do not have to feed sha1s; you can feed arbitrary
sha1 expressions and have git resolve them en masse.
3. You can even feed a raw sha1, with the result that git
will tell you whether we actually have the object or
not.
In case 3, the call to sha1_object_info is useful; it tells
us whether the object exists or not (technically we could
swap this out for has_sha1_file, but the cost is roughly the
same).
In case 2, the existence check is of debatable value. A
mass-resolution might prefer performance to safety (against
outputting a value for a corrupted ref, for example).
However, the object lookup cost is likely not as noticeable
compared to the resolution cost. And since we have provided
that safety in the past, the conservative choice is to keep
it.
In case 1, though, the object lookup is a definite noop; we
know about the object because we found it in the object
database. There is no new information gained by making the
call.
This patch detects that case and optimizes out the call.
Here are best-of-five timings for linux.git:
[before]
$ time git cat-file --buffer \
--batch-all-objects \
--batch-check='%(objectname)'
real 0m2.117s
user 0m2.044s
sys 0m0.072s
[after]
$ time git cat-file --buffer \
--batch-all-objects \
--batch-check='%(objectname)'
real 0m1.230s
user 0m1.176s
sys 0m0.052s
There are two implementation details to note here.
One is that we detect the noop case by seeing that "struct
object_info" does not request any information. But besides
object existence, there is one other piece of information
which sha1_object_info may fill in: whether the object is
cached, loose, or packed. We don't currently provide that
information in the output, but if we were to do so later,
we'd need to take note and disable the optimization in that
case.
And that leads to the second note. If we were to output
that information, a better implementation would be to
remember where we saw the object in --batch-all-objects in
the first place, and avoid looking it up again by sha1.
In fact, we could probably squeeze out some extra
performance for less-trivial cases, too, by remembering the
pack location where we saw the object, and going directly
there to find its information (like type, size, etc). That
would in theory make this optimization unnecessary.
I didn't pursue that path here for two reasons:
1. It's non-trivial to implement, and has memory
implications. Because we sort and de-dup the list of
output sha1s, we'd have to record the pack information
for each object, too.
2. It doesn't save as much as you might hope. It saves the
find_pack_entry() call, but getting the size and type
for deltified objects requires walking down the delta
chain (for the real type) or reading the delta data
header (for the size). These costs tend to dominate the
non-trivial cases.
By contrast, this optimization is easy and self-contained,
and speeds up a real-world case I've used.

When running diff commands, a pathspec containing decomposed
unicode code points is not converted to precomposed unicode form
under Mac OS X, but we normalize the paths in the index and the
history to precomposed form on that platform. As a result, the
pathspec would not match and no diff is shown.
Unlike many builtin commands, the "diff" family of commands do
not use parse_options(), which is how other builtin commands
indirectly call precompose_argv() to normalize argv[] into
precomposed form on Mac OSX. Teach these commands to call
precompose_argv() themselves.
Note that precomopose_argv() normalizes not just paths but all
command line arguments, so things like "git diff -G $string"
when $string has the decomposed form would first be normalized
into the precomposed form and would stop hitting the same string
in the decomposed form in the diff output with this change.
It is not a problem per-se, as "log" family of commands already use
parse_options() and call precompose_argv()--we can think of this
change as making the "diff" family of commands behave in a similar
way as the commands in the "log" family.

Currently commands that want to use the apply functionality have to launch
a "git apply" process which can be bad for performance.
Let's start libifying the apply functionality and to do that we first need
to get rid of the global variables in "builtin/apply.c".
This patch introduces "struct apply_state" into which all the previously
global variables will be moved. A new parameter called "state" that is a
pointer to the "apply_state" structure will come at the beginning of the
helper functions that need it and will be passed around the call chain.
To start let's move the "prefix" and "prefix_length" global variables into
"struct apply_state".

The point of having a whitelist of command-line config
options to pass to submodules was two-fold:
1. It prevented obvious nonsense like using core.worktree
for multiple repos.
2. It could prevent surprise when the user did not mean
for the options to leak to the submodules (e.g.,
http.sslverify=false).
For case 1, the answer is mostly "if it hurts, don't do
that". For case 2, we can note that any such example has a
matching inverted surprise (e.g., a user who meant
http.sslverify=true to apply everywhere, but it didn't).
So this whitelist is probably not giving us any benefit, and
is already creating a hassle as people propose things to put
on it. Let's just drop it entirely.
Note that we still need to keep a special code path for
"prepare the submodule environment", because we still have
to take care to pass through $GIT_CONFIG_PARAMETERS (and
block the rest of the repo-specific environment variables).
We can do this easily from within the submodule shell
script, which lets us drop the submodule--helper option
entirely (and it's OK to do so because as a "--" program, it
is entirely a private implementation detail).

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.
Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine. Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.
Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree". If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").
Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow. E.g.
case $(git config --bool commit.gpgsign) in
true) sign=-S ;;
*) sign= ;;
esac &&
git commit-tree $sign ...whatever other args...
Do so to make sure that "git rebase" keeps paying attention to the
configuration variable, which unfortunately is a documented mistake.

When running "git blame $path" with unnormalized data in the index
for the path, the data in the working tree was blamed, even though
"git add" would not have changed what is already in the index, due
to "safe crlf" that disables the line-end conversion. It has been
corrected.

"git mv old new" did not adjust the path for a submodule that lives
as a subdirectory inside old/ directory correctly.

When there is no .gitmodules file availabe to initialize a submodule
from, `submodule_from_path` just returns NULL. We need to check for
that and abort gracefully.
When `git submodule update` was implemented in shell, this error out
with the warning
Submodule path '%s' not initialized
Maybe you want to use 'update --init'?
Replicate that behavior for now instead of crashing.

a missing .gitmodules file would result in an error message
No url found for submodule path '%s' in .gitmodules
Replicate that error message for now.
When the .gitmodules file is missing we can probably fail even earlier
for all of the submodules with an improved error message.

These functions should be used by any code which spawns a
submodule process, which may happen in submodule.c (e.g.,
for spawning fetch). Let's move them there and make them
public so that submodule--helper can continue to use them.
Since they're now public, let's also provide a basic overview
of their intended use.

It can be tempting for a server admin to want a stable set of
long-lived packs for dumb clients; but also want to enable bitmaps
to serve smart clients more quickly.
Unfortunately, such a configuration is impossible; so at least warn
users of this incompatibility since commit 21134714 (pack-objects:
turn off bitmaps when we split packs, 2014-10-16).
Tested the warning by inspecting the output of:
make -C t t5310-pack-bitmaps.sh GIT_TEST_OPTS=-v

This allows to record the base commit automatically, it is equivalent
to set --base=auto in cmdline.
The format.useAutoBase has lower priority than command line option,
so if user set format.useAutoBase and pass the command line option in
the meantime, base_commit will be the one passed to command line
option.

Introduce --base=auto to record the base commit info automatically, the
base_commit will be the merge base of tip commit of the upstream branch
and revision-range specified in cmdline.

Maintainers or third party testers may want to know the exact base tree
the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).
The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.
The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name. A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.
Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:
---P---X---Y---Z---A---B---C
With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:
base-commit: P
prerequisite-patch-id: X
prerequisite-patch-id: Y
prerequisite-patch-id: Z

When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:
* shallow super project with shallow submodules
e.g. build bots starting always from scratch. They want to transmit
the least amount of network data as well as using the least amount
of space on their hard drive.
* shallow super project with unshallow submodules
e.g. The superproject is just there to track a collection of repositories
and it is not important to have the relationship between the repositories
intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
e.g. The superproject is the actual project and the submodule is a
library which is rarely touched.
The new switch to select submodules to be shallow or unshallow supports
all of these three cases.
It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

When "git merge" notices that the merge can be resolved purely at
the tree level (without having to merge blobs) and the resulting
tree happens to already exist in the object store, it forgot to
update the index, which lead to an inconsistent state for later
