Migrate all git_path_* functions that are defined in path.c to take a
repository argument. Unlike other patches in this series, do not use the
#define trick, as we rewrite the whole function, which is rather small.
This doesn't migrate all the functions, as other builtins have their own
local path functions defined using GIT_PATH_FUNC. So keep that macro
around to serve the other locations.

Teach fetch to generate ref-prefixes, to be used for server-side

When using protocol v2 a client constructs a list of ref-prefixes which
are sent across the wire so that the server can do server-side filtering
of the ref-advertisement. The logic that does this exists for both
fetch and push (even though no push support for v2 currently exists yet)
and is roughly the same so lets consolidate this logic and make it
general enough that it can be used for both the push and fetch cases.

- write_object_file
As a result, most of the codebase needs to #include object-store.h.
In this patch the #include is only added to files that would fail to

After performing a merge that has conflicts git status will, by default,
attempt to detect renames which causes many objects to be examined. In a
virtualized repo, those objects do not exist locally so the rename logic
triggers them to be fetched from the server. This results in the status call
taking hours to complete on very large repos vs seconds with this patch.
Add a new config status.renames setting to enable turning off rename
detection during status and commit. This setting will default to the value
of diff.renames.
Add a new config status.renamelimit setting to to enable bounding the time
spent finding out inexact renames during status and commit. This setting
will default to the value of diff.renamelimit.
Add --no-renames command line option to status that enables overriding the
config setting from the command line. Add --find-renames[=<n>] command line
option to status that enables detecting renames and optionally setting the

The compiler is correct, and the error message speaks for itself. There
is no need for any undefined operation -- just cast mark to void * or
uint32_t after an intermediate cast to uintptr_t. That encodes the
integer value into a pointer and later decodes it as intended.

Placing `struct lock_file`s on the stack used to be a bad idea, because
the temp- and lockfile-machinery would keep a pointer into the struct.
But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap,
2017-09-05), we can safely have lockfiles on the stack. (This applies
even if a user returns early, leaving a locked lock behind.)
Each of these `struct lock_file`s is used from within a single function.
Move them into the respective functions to make the scope clearer and
drop the staticness.
For good measure, I have inspected these sites and come to believe that
they always release the lock, with the possible exception of bailing out
using `die()` or `exit()` or by returning from a `cmd_foo()`.
As pointed out by Jeff King, it would be bad if someone held on to a
`struct lock_file *` for some reason. After some grepping, I agree with
his findings: no-one appears to be doing that.
After this commit, the remaining occurrences of "static struct
lock_file" are locks that are used from within different functions. That
is, they need to remain static. (Short of more intrusive changes like
passing around pointers to non-static locks.)

In d8193743e0 (usage.c: add BUG() function, 2017-05-12), a new macro

If you do something like
- git add .
- git status
- git commit
- git show (or git diff HEAD)
one would expect to have analogous output from git status and git show
(or similar diff-related programs). This is generally not the case, as
git status has hard coded values for diff related options.
With this commit the hard coded settings are dropped from the status
command in favour for values provided by git_diff_ui_config.
What follows are some remarks on the concrete options which were hard
coded in git status:
diffopt.detect_rename
Since the very beginning of git status in a3e870f2e2 ("Add "commit"
helper script", 2005-05-30), git status always used rename detection,
whereas with commands like show and log one had to activate it with a
command line option. After 5404c116aa ("diff: activate diff.renames by
default", 2016-02-25) the default behaves the same by coincidence, but
changing diff.renames to other values can break the consistency between
git status and other commands again. With this commit one control the
same default behaviour with diff.renames.
diffopt.rename_limit
Similarly one has the option diff.renamelimit to adjust this limit for
all commands but git status. With this commit git status will also honor
those.
diffopt.break_opt
Unlike the other two options this cannot be configured by a
configuration option yet. This commit will also change the default
behaviour to not use break rewrites. But as rename detection is most
likely on, this is dangerous to be activated anyway as one can see
here:

for a hex value to use the hex constant instead, as the original appears
to have been a typo.
At this point, avoid converting the hard-coded use of SHA-1 to use
the_hash_algo. SHA-1, even if not collision resistant, is secure in the
context in which it is used here, and the hash algorithm of the repo
need not match what is used here. When we adopt a new hash algorithm,
we can simply adopt the new algorithm wholesale here, as the nonce is
opaque and its length and validity are entirely controlled by the
server. Consequently, defer updating this code until that point.

When converting all grafts in a graft file to replace refs, and one of
them happens to leave the original commit's parents unchanged, we do not
want to error out. Instead, we would like to issue a warning.
Prepare the create_graft() function for such a use case by adding a

is unchanged, but a mere warning.

Currently 'git worktree add <path>' creates a new branch named after the
basename of the path by default. If a branch with that name already
exists, the command refuses to do anything, unless the '--force' option
is given.
However we can do a little better than that, and check the branch out if
it is not checked out anywhere else. This will help users who just want
to check an existing branch out into a new worktree, and save a few
keystrokes.
As the current behaviour is to simply 'die()' when a branch with the name
of the basename of the path already exists, there are no backwards
compatibility worries here.
We will still 'die()' if the branch is checked out in another worktree,
unless the --force flag is passed.

Currently 'git worktree add' produces output like the following:
Preparing ../foo (identifier foo)
HEAD is now at 26da330922 <title>
The '../foo' is the path where the worktree is created, which the user
has just given on the command line. The identifier is an internal
implementation detail, which is not particularly relevant for the user
and indeed isn't mentioned explicitly anywhere in the man page.
Instead of this message, print a message that gives the user a bit more
detail of what exactly 'git worktree' is doing. There are various dwim
modes which perform some magic under the hood, which should be
helpful to users. Just from the output of the command it is not always
visible to users what exactly has happened.
Help the users a bit more by modifying the "Preparing ..." message and
adding some additional information of what 'git worktree add' did under
the hood, while not displaying the identifier anymore.
Currently there are several different cases:
- 'git worktree add -b ...' or 'git worktree add <path>', both of
which create a new branch, either through the user explicitly
requesting it, or through 'git worktree add' implicitly creating
it. This will end up with the following output:
Preparing worktree (new branch '<branch>')
HEAD is now at 26da330922 <title>
- 'git worktree add -B ...', which may either create a new branch if
the branch with the given name does not exist yet, or resets an
existing branch to the current HEAD, or the commit-ish given.
Depending on which action is taken, we'll end up with the following
output:
Preparing worktree (resetting branch '<branch>'; was at caa68db14)
HEAD is now at 26da330922 <title>
or:
Preparing worktree (new branch '<branch>')
HEAD is now at 26da330922 <title>
- 'git worktree add --detach' or 'git worktree add <path>
<commit-ish>', both of which create a new worktree with a detached
HEAD, for which we will print the following output:
Preparing worktree (detached HEAD 26da330922)
HEAD is now at 26da330922 <title>
- 'git worktree add <path> <local-branch>', which checks out the
branch and prints the following output:
Preparing worktree (checking out '<local-branch>')
HEAD is now at 47007d5 <title>
Additionally currently the "Preparing ..." line is printed to stderr,
while the "HEAD is now at ..." line is printed to stdout by 'git reset
--hard', which is used internally by 'git worktree add'. Fix this
inconsistency by printing the "Preparing ..." message to stdout as
well. As "Preparing ..." is not an error, stdout also seems like the
more appropriate output stream.

This is yet another patch to be filed under the keyword "libification".
There is one subtle change in behavior here, where a `git log` that has

upon the first failure, whereas previously, it would have continued to the

In practice, that change should not matter, as it is 1) uncommon to

When running `git rebase --rebase-merges` non-interactively with an
ancestor of HEAD as <upstream> (or leaving the todo list unmodified),
we would ideally recreate the exact same commits as before the rebase.
However, if there are commits in the commit range <upstream>.. that do not
have <upstream> as direct ancestor (i.e. if `git log <upstream>..` would
show commits that are omitted by `git log --ancestry-path <upstream>..`),
this is currently not the case: we would turn them into commits that have
<upstream> as direct ancestor.
Let's illustrate that with a diagram:
C
/ \
A - B - E - F
\ /
D
Currently, after running `git rebase -i --rebase-merges B`, the new branch
structure would be (pay particular attention to the commit `D`):
--- C' --
/ \
A - B ------ E' - F'
\ /
D'
This is not really preserving the branch topology from before! The
reason is that the commit `D` does not have `B` as ancestor, and
therefore it gets rebased onto `B`.
This is unintuitive behavior. Even worse, when recreating branch
structure, most use cases would appear to want cousins *not* to be
rebased onto the new base commit. For example, Git for Windows (the
heaviest user of the Git garden shears, which served as the blueprint
for --rebase-merges) frequently merges branches from `next` early, and
these branches certainly do *not* want to be rebased. In the example
above, the desired outcome would look like this:
--- C' --
/ \
A - B ------ E' - F'
\ /
-- D' --
Let's introduce the term "cousins" for such commits ("D" in the
example), and let's not rebase them by default. For hypothetical
use cases where cousins *do* need to be rebased, `git rebase
--rebase=merges=rebase-cousins` needs to be used.

The sequencer just learned new commands intended to recreate branch
structure (similar in spirit to --preserve-merges, but with a
substantially less-broken design).
Let's allow the rebase--helper to generate todo lists making use of
these commands, triggered by the new --rebase-merges option. For a
commit topology like this (where the HEAD points to C):
- A - B - C
\ /
D
the generated todo list would look like this:
# branch D
pick 0123 A
label branch-point
pick 1234 D
label D
reset branch-point
pick 2345 B
merge -C 3456 D # C
To keep things simple, we first only implement support for merge commits
with exactly two parents, leaving support for octopus merges to a later
patch series.
All merge-rebasing todo lists start with a hard-coded `label onto` line.
This makes it convenient to refer later on to the revision onto which
everything is rebased, e.g. as starting point for branches other than
the very first one.

As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.
This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).
With the addition of `--default`, this is no longer needed since:
$ git config --default red --type=color core.section
will be have exactly as:
$ git config --get-color core.section red
For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.

For some use cases, callers of the `git-config(1)` builtin would like to
fallback to default values when the variable asked for does not exist.
In addition, users would like to use existing type specifiers to ensure
that values are parsed correctly when they do exist in the
configuration.
For example, to fetch a value without a type specifier and fallback to
`$fallback`, the following is required:
$ git config core.foo || echo "$fallback"
This is fine for most values, but can be tricky for difficult-to-express
`$fallback`'s, like ANSI color codes.
This motivates `--get-color`, which is a one-off exception to the normal
type specifier rules wherein a user specifies both the configuration
variable and an optional fallback. Both are formatted according to their
type specifier, which eases the burden on the user to ensure that values
are correctly formatted.
This commit (and those following it in this series) aim to eventually
replace `--get-color` with a consistent alternative. By introducing
`--default`, we allow the `--get-color` action to be promoted to a
`--type=color` type specifier, retaining the "fallback" behavior via the
`--default` flag introduced in this commit.
For example, we aim to replace:
$ git config --get-color variable [default] [...]
with:
$ git config --default default --type=color variable [...]
Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuration.
Specifically, this means that the following will work:
$ git config --int --default 1M does.not.exist
1048576
In subsequent commits, we will offer `--type=color`, which (in
conjunction with `--default`) will be sufficient to replace
`--get-color`.

A few commands that parse --expire=<time> command line option behave
sillily when given nonsense input. For example
$ git prune --no-expire
Segmentation falut
$ git prune --expire=npw; echo $?
129
Both come from parse_opt_expiry_date_cb().
The former is because the function is not prepared to see arg==NULL
(for "--no-expire", it is a norm; "--expire" at the end of the
command line could be made to pass NULL, if it is told that the
argument is optional, but we don't so we do not have to worry about
that case).
The latter is because it does not check the value returned from the
underlying parse_expiry_date().
This seems to be a recent regression introduced while we attempted
to avoid spewing the entire usage message when given a correct
option but with an invalid value at 3bb0923f ("parse-options: do not
show usage upon invalid option value", 2018-03-22). Before that, we
didn't fail silently but showed a full usage help (which arguably is
not all that better).
Also catch this error early when "git gc --prune=<expiration>" is
misspelled by doing a dummy parsing before the main body of "gc"
that is time consuming even begins. Otherwise, we'd spend time to
pack objects and then later have "git prune" first notice the error.
Aborting "gc" in the middle that way is not harmful but is ugly and
can be avoided.

7199203937 (object_array: add and use `object_array_pop()`, 2017-09-23)
noted that the pattern `object = array.objects[--array.nr].item` could
be abstracted as `object = object_array_pop(&array)`.
Unfortunately, one of the conversions was horribly wrong. Between
grabbing the last object (i.e., peeking at it) and decreasing the object
count, the original code would sometimes return early. The updated code
on the other hand, will always pop the last element, then maybe do the
early return without doing anything with the object.
The end result is that merge commits where all the parents have still
not been exported will simply be dropped, meaning that they will be
completely missing from the exported data.
Re-add a commit when it is not yet time to handle it. An alternative
that was considered was to peek-then-pop. That carries some risk with it
since the peeking and popping need to act on the same object, in a
concerted fashion.
Add a test that would have caught this.

`git config` has long allowed the ability for callers to provide a 'type
specifier', which instructs `git config` to (1) ensure that incoming
values can be interpreted as that type, and (2) that outgoing values are
canonicalized under that type.
In another series, we propose to extend this functionality with
`--type=color` and `--default` to replace `--get-color`.
However, we traditionally use `--color` to mean "colorize this output",
instead of "this value should be treated as a color".
Currently, `git config` does not support this kind of colorization, but
we should be careful to avoid squatting on this option too soon, so that
`git config` can support `--color` (in the traditional sense) in the
future, if that is desired.
In this patch, we support `--type=<int|bool|bool-or-int|...>` in
addition to `--int`, `--bool`, and etc. This allows the aforementioned
upcoming patch to support querying a color value with a default via
`--type=color --default=...`, without squandering `--color`.
We retain the historic behavior of complaining when multiple,
legacy-style `--<type>` flags are given, as well as extend this to
conflicting new-style `--type=<type>` flags. `--int --type=int` (and its
commutative pair) does not complain, but `--bool --type=int` (and its
commutative pair) does.

pack-objects could be a big memory hog especially on large repos,
everybody knows that. The suggestion to stick a .keep file on the
giant base pack to avoid this problem is also known for a long time.
Recent patches add an option to do just this, but it has to be either
configured or activated manually. This patch lets `git gc --auto`
activate this mode automatically when it thinks `repack -ad` will use
a lot of memory and start affecting the system due to swapping or
flushing OS cache.
gc --auto decides to do this based on an estimation of pack-objects
memory usage, which is quite accurate at least for the heap part, and
whether that fits in half of system memory (the assumption here is for
desktop environment where there are many other applications running).
This mechanism only kicks in if gc.bigBasePackThreshold is not configured.
If it is, it is assumed that the user already knows what they want.

We could tell the user that they have incompatible gc.bigPackThreshold

background. Instead let's fall back to the next best stategy: try to
reduce the number of packs anyway, but keep the base pack out. This

We allow to keep existing packs by having companion .keep files. This
is helpful when a pack is permanently kept. In the next patch, git-gc
just wants to keep a pack temporarily, for one pack-objects
run. git-gc can use --keep-pack for this use case.
A note about why the pack_keep field cannot be reused and
pack_keep_in_core has to be added. This is about the case when
--keep-pack is specified together with either --keep-unreachable or
--unpack-unreachable, but --honor-pack-keep is NOT specified.
In this case, we want to exclude objects from the packs specified on
command line, not from ones with .keep files. If only one bit flag is
used, we have to clear pack_keep on pack files with the .keep file.
But we can't make any assumption about unreachable objects in .keep
packs. If "pack_keep" field is false for .keep packs, we could
potentially pull lots of unreachable objects into the new pack, or
unpack them loose. The safer approach is ignore all packs with either
.keep file or --keep-pack.

Allowing a delta size of 64 bits is crazy. Shrink this field down to
20 bits with one overflow bit.
If we find an existing delta larger than 1MB, we do not cache
delta_size at all and will get the value from oe_size(), potentially
from disk if it's larger than 4GB.
Note, since DELTA_SIZE() is used in try_delta() code, it must be
thread-safe. Luckily oe_size() does guarantee this so we it is
thread-safe.

It's very very rare that an uncompressed object is larger than 4GB
(partly because Git does not handle those large files very well to
begin with). Let's optimize it for the common case where object size
is smaller than this limit.
Shrink size field down to 31 bits and one overflow bit. If the size is
too large, we read it back from disk. As noted in the previous patch,
we need to return the delta size instead of canonical size when the
to-be-reused object entry type is a delta instead of a canonical one.
Add two compare helpers that can take advantage of the overflow
bit (e.g. if the file is 4GB+, chances are it's already larger than
core.bigFileThreshold and there's no point in comparing the actual
value).
Another note about oe_get_size_slow(). This function MUST be thread
safe because SIZE() macro is used inside try_delta() which may run in
parallel. Outside parallel code, no-contention locking should be dirt
cheap (or insignificant compared to i/o access anyway). To exercise
this code, it's best to run the test suite with something like
make test GIT_TEST_OE_SIZE=4
which forces this code on all objects larger than 3 bytes.

While this field most of the time contains the canonical object size,
there is one case it does not: when we have found that the base object
of the delta in question is also to be packed, we will very happily
reuse the delta by copying it over instead of regenerating the new
delta.
"size" in this case will record the delta size, not canonical object
size. Later on in write_reuse_object(), we reconstruct the delta
header and "size" is used for this purpose. When this happens, the
"type" field contains a delta type instead of a canonical type.
Highlight this in the code since it could be tricky to see.

sha1_object_info() in check_objects() may fail to locate an object in
the pack and return type OBJ_BAD. In that case, it will likely leave
the "size" field untouched. We delay error handling until later in
prepare_pack() though. Until then, do not touch "size" field.
This field should contain the default value zero, but we can't say
sha1_object_info() cannot damage it. This becomes more important later
when the object size may have to be retrieved back from the
(non-existing) pack.

These delta pointers always point to elements in the objects[] array
in packing_data struct. We can only hold maximum 4G of those objects
because the array size in nr_objects is uint32_t. We could use
uint32_t indexes to address these elements instead of pointers. On
64-bit architecture (8 bytes per pointer) this would save 4 bytes per
pointer.
Convert these delta pointers to indexes. Since we need to handle NULL
pointers as well, the index is shifted by one [1].
[1] This means we can only index 2^32-2 objects even though nr_objects
could contain 2^32-1 objects. It should not be a problem in
practice because when we grow objects[], nr_alloc would probably
blow up long before nr_objects hits the wall.

Instead of using 8 bytes (on 64 bit arch) to store a pointer to a
pack. Use an index instead since the number of packs should be
relatively small.
This limits the number of packs we can handle to 1k. Since we can't be
sure people can never run into the situation where they have more than
1k pack files. Provide a fall back route for it.
If we find out they have too many packs, the new in_pack_by_idx[]
array (which has at most 1k elements) will not be used. Instead we
allocate in_pack[] array that holds nr_objects elements. This is
similar to how the optional in_pack_pos field is handled.
The new simple test is just to make sure the too-many-packs code path
is at least executed. The true test is running
make test GIT_TEST_FULL_IN_PACK_ARRAY=1
to take advantage of other special case tests.

An extra field type_valid is added to carry the equivalent of OBJ_BAD
in the original "type" field. in_pack_type always contains a valid
type so we only need 3 bits for it.
A note about accepting OBJ_NONE as "valid" type. The function
read_object_list_from_stdin() can pass this value [1] and it
eventually calls create_object_entry() where current code skip setting
"type" field if the incoming type is zero. This does not have any bad
side effects because "type" field should be memset()'d anyway.
But since we also need to set type_valid now, skipping oe_set_type()
leaves type_valid zero/false, which will make oe_type() return
OBJ_BAD, not OBJ_NONE anymore. Apparently we do care about OBJ_NONE in
prepare_pack(). This switch from OBJ_NONE to OBJ_BAD may trigger
fatal: unable to get type of object ...
Accepting OBJ_NONE [2] does sound wrong, but this is how it is has
been for a very long time and I haven't time to dig in further.

Using the commit-graph file to walk commit history removes the large

issue: lookup_tree() takes a large portion of the computation time,
even when Git never uses those trees.
In anticipation of lazy-loading these trees, rename the 'tree' member
of struct commit to 'maybe_tree'. This serves two purposes: it hints
at the future role of possibly being NULL even if the commit has a
valid tree, and it allows for unambiguous transformation from simple

Internally, we represent `git config`'s type specifiers as a bitset
using OPT_BIT. 'bool' is 1<<0, 'int' is 1<<1, and so on. This technique
allows for the representation of multiple type specifiers in the `int
types` field, but this multi-representation is left unused.
In fact, `git config` will not accept multiple type specifiers at a
time, as indicated by:
$ git config --int --bool some.section
error: only one type at a time.
This patch uses `OPT_SET_INT` to prefer the _last_ mentioned type
specifier, so that the above command would instead be valid, and a
synonym of:
$ git config --bool some.section
This change is motivated by two urges: (1) it does not make sense to
represent a singular type specifier internally as a bitset, only to
complain when there are multiple bits in the set. `OPT_SET_INT` is more
well-suited to this task than `OPT_BIT` is. (2) a future patch will
introduce `--type=<type>`, and we would like not to complain in the
following situation:

As submodules are identified by their name (which determines their git

converted to also take "struct repository *" arguments. Among them were
grep_object() and grep_objects().
However, at least grep_objects() was converted incompletely - it calls
gitmodules_config_oid(), which references the_repository.
But it turns out that the conversion was extraneous anyway - there has
been no user-visible effect - because grep_objects() is never invoked
except with the_repository. This is because grepping through objects
cannot be done recursively into submodules.
Revert the changes to grep_objects() and grep_object() (which conversion
is also extraneous) to show that both these functions do not support
