check_linked_checkout() only understands symref-style HEAD (i.e. "ref:
refs/heads/master"), however, HEAD may also be a an actual symbolic link
(on platforms which support it), thus it will need to check that style
HEAD, as well (via readlink()). As a preparatory step, simplify parsing
of symref-style HEAD so the actual branch check can be re-used easily
for symbolic links (in an upcoming patch).

When check_linked_checkout() discovers that the branch is already
checked out elsewhere, it emits the diagnostic:
'blorp' is already checked out at '/some/path/.git'
which is misleading since "checked out at" implies the working tree, but
".git" is the location of the repository administrative files. Fix by
dropping ".git" from the message.

The plan is to publish die_if_checked_out() so that callers other than
git-checkout can take advantage of it, however, those callers won't have
access to git-checkout's "struct branch_info". Therefore, change it to

While here, also give the argument a more meaningful name ("branch"

die_if_checked_out() is intended to check if the branch about to be
checked out is already checked out either in the main worktree or in a
linked worktree. However, if .git/worktrees directory does not exist,
then it never bothers checking the main worktree, even though the
specified branch might indeed be checked out there, which is fragile
behavior.
This hasn't been a problem in practice since the current implementation
of "git worktree add" (and, earlier, "git checkout --to") always creates
.git/worktrees before die_if_checked_out() is called by the child "git
checkout" invocation which populates the new worktree.
However, git-worktree will eventually want to call die_if_checked_out()
itself rather than only doing so indirectly as a side-effect of invoking
git-checkout, and reliance upon order of operations (creating
.git/worktrees before checking if a branch is already checked out) is
fragile. As a general function, callers should not be expected to abide
by this undocumented and unwarranted restriction. Therefore, make
die_if_checked_out() more robust by checking the main worktree whether
.git/worktrees exists or not.
While here, also move a comment explaining why die_if_checked_out()'s
helper parses HEAD manually. Such information resides more naturally
with the helper itself rather than at its first point of call.

check_linked_checkouts() doesn't just "check" linked checkouts for

Given "git checkout --to <path> HEAD~1", the new worktree's HEAD should
begin life at the current branch's HEAD~1, however, it actually ends up
at HEAD~2. This happens because:
1. git-checkout resolves HEAD~1
2. to satisfy is_git_directory(), prepare_linked_worktree() creates
a HEAD for the new worktree with the value of the resolved HEAD~1
3. git-checkout re-invokes itself with the same arguments within the
new worktree to populate the worktree
4. the sub git-checkout resolves HEAD~1 relative to its own HEAD,
which is the resolved HEAD~1 from the original invocation,
resulting unexpectedly and incorrectly in HEAD~2 (relative to the
original)
Fix this by unconditionally assigning the current worktree's HEAD as the
value of the new worktree's HEAD.
As a side-effect, this change also eliminates a dependence within
prepare_linked_checkout() upon 'struct branch_info'. The plan is to
eventually relocate "git checkout --to" functionality to "git worktree
add", and worktree.c won't have knowledge of 'struct branch_info', so
removal of this dependency is a step toward that goal.

When c6458e60 (index-pack: kill union delta_base to save memory,
2015-04-18) attempted to reduce the memory footprint of index-pack,
one of the key thing it did was to keep track of ref-deltas and
ofs-deltas separately.
In fix_unresolved_deltas(), however it forgot that it now wants to
look only at ref deltas in one place. The code allocated an array
for nr_unresolved, which is sum of number of ref- and ofs-deltas
minus nr_resolved, which may be larger or smaller than the number
ref-deltas. Depending on nr_resolved, this was either under or over
allocating.
Also, the old code before this change had to use 'i' and 'n' because
some of the things we see in the (old) deltas[] array we scanned
with 'i' would not make it into the sorted_by_pos[] array in the old
world order, but now because you have only ref delta in a separate
ref_deltas[] array, they increment lock&step. We no longer need
separate variables. And most importantly, we shouldn't pass the
nr_unresolved parameter, as this number does not play a role in the
working of this helper function.

In preparation for adding date modes that may carry extra
information beyond the mode itself, this patch converts the
date_mode enum into a struct.
Most of the conversion is fairly straightforward; we pass
the struct as a pointer and dereference the type field where
necessary. Locations that declare a date_mode can use a "{}"
constructor. However, the tricky case is where we use the
enum labels as constants, like:
show_date(t, tz, DATE_NORMAL);
Ideally we could say:
show_date(t, tz, &{ DATE_NORMAL });
but of course C does not allow that. Likewise, we cannot
cast the constant to a struct, because we need to pass an
actual address. Our options are basically:
1. Manually add a "struct date_mode d = { DATE_NORMAL }"
definition to each caller, and pass "&d". This makes
the callers uglier, because they sometimes do not even
have their own scope (e.g., they are inside a switch
statement).
2. Provide a pre-made global "date_normal" struct that can
be passed by address. We'd also need "date_rfc2822",
"date_iso8601", and so forth. But at least the ugliness
is defined in one place.
3. Provide a wrapper that generates the correct struct on
the fly. The big downside is that we end up pointing to
a single global, which makes our wrapper non-reentrant.
But show_date is already not reentrant, so it does not
matter.
This patch implements 3, along with a minor macro to keep
the size of the callers sane.

If this extension is used in a repository, then no
operations should run which may drop objects from the object
storage. This can be useful if you are sharing that storage
with other repositories whose refs you cannot see.
For instance, if you do:
$ git clone -s parent child
$ git -C parent config extensions.preciousObjects true
$ git -C parent config core.repositoryformatversion 1
you now have additional safety when running git in the
parent repository. Prunes and repacks will bail with an
error, and `git gc` will skip those operations (it will
continue to pack refs and do other non-object operations).
Older versions of git, when run in the repository, will
fail on every operation.
Note that we do not set the preciousObjects extension by
default when doing a "clone -s", as doing so breaks
backwards compatibility. It is a decision the user should

We already have support in `git receive-pack` to deal with some legacy

Let's make `git fsck` itself useful with such repositories, too, by
allowing users to ignore known issues, or at least demote those issues
to mere warnings.
Example: `git -c fsck.missingEmail=ignore fsck` would hide
problems with missing emails in author, committer and tagger lines.
In the same spirit that `git receive-pack`'s usage of the fsck machinery
differs from `git fsck`'s – some of the non-fatal warnings in `git fsck`
are fatal with `git receive-pack` when receive.fsckObjects = true, for
example – we strictly separate the fsck.<msg-id> from the
receive.fsck.<msg-id> settings.

lines in the config, the latter configuration wins (this can happen for
example when both $HOME/.gitconfig and .git/config contain message type
settings).
As git receive-pack does not actually perform the checks, it hands off

This reverts commit d95d728aba.
It turns out that many other commands that need to interact with the
result of running diff-files and diff-index, e.g. "git apply", "git
rm", etc., need to be adjusted to the new world order it brings in.
For example, it would break this sequence to correct a whitespace
breakage in the parts you changed:
git add -N file
git diff --cached file | git apply --cached --whitespace=fix
git checkout file
In the old world order, "diff" showed a patch to modify an existing
empty file by adding its full contents, and "apply" updated the
index by modifying the existing empty blob (which is what an
Intent-to-Add entry records in the index) with that patch.
In the new world order, "diff" shows a patch to create a new file
with its full contents, but because "apply" thinks that the i-t-a
entry already exists in the index, it refused to accept a creation.
Adjusting "apply" to this new world order is easy, but we need to
assess the extent of the damage to the rest of the system the new
world order brought in before going forward and adjust them all,
after which we can resurrect the commit being reverted here.

objects, it's an order of magnitude faster to just
enumerate the loose directories and pack indices.
You can do this yourself using "ls" and "git show-index",
but it's non-obvious. This patch adds an option to
"cat-file --batch-check" to operate on all available
objects (rather than reading names from stdin).
This is based on a proposal by Charles Bailey to provide a
separate "git list-all-objects" command. That is more
orthogonal, as it splits enumerating the objects from
getting information about them. However, in practice you
will either:
a. Feed the list of objects directly into cat-file anyway,
so you can find out information about them. Keeping it
in a single process is more efficient.
b. Ask the listing process to start telling you more
information about the objects, in which case you will
reinvent cat-file's batch-check formatter.
Adding a cat-file option is simple and efficient. And if you
really do want just the object names, you can always do:
git cat-file --batch-check='%(objectname)' --batch-all-objects

If batch_one_object returns an error code, we stop reading
input. However, it will only do so if we feed it NULL,
which cannot happen; we give it the "buf" member of a
strbuf, which is always non-NULL.
We did originally stop on other errors (like a missing
object), but this was changed in 3c076db (cat-file --batch /
--batch-check: do not exit if hashes are missing,
2008-06-09). These days we keep going for any per-object

We use a direct write() to output the results of --batch and

and reading the output interactively, but it introduces

$ git rev-list --objects --all | cut -d' ' -f1 >objects
$ time git cat-file --batch-check='%(objectsize)' \
<objects >/dev/null

The ref_transaction_update() family of functions use the following
convention for their old_sha1 parameters:
* old_sha1 == NULL: Don't check the old value at all.
* is_null_sha1(old_sha1): Ensure that the reference didn't exist
before the transaction.
* otherwise: Ensure that the reference had the specified value before
the transaction.
delete_ref() had a different convention, namely treating
is_null_sha1(old_sha1) as "don't care". Change it to adhere to the
standard convention to reduce the scope for confusion.
Please note that it is now a bug to pass old_sha1=NULL_SHA1 to
delete_ref() (because it doesn't make sense to delete a reference that
you already know doesn't exist). This is consistent with the behavior
of ref_transaction_delete().
Most of the callers of delete_ref() never pass old_sha1=NULL_SHA1 to
delete_ref(), and are therefore unaffected by this change. The
two exceptions are:
* The call in cmd_update_ref(), which passed NULL_SHA1 if the old
value passed in on the command line was 0{40} or the empty string.
Change that caller to pass NULL in those cases.
Arguably, it should be an error to call "update-ref -d" with the old
value set to "does not exist", just as it is for the `--stdin`
command "delete". But since this usage was accepted until now,
continue to accept it.
* The call in delete_branches(), which could pass NULL_SHA1 if
deleting a broken or symbolic ref. Change it to pass NULL in these
cases.

"git clone" uses shortcuts when creating the initial set of
references:
* It writes them directly to packed-refs.
* It doesn't lock the individual references (though it does lock the
packed-refs file).
* It doesn't check for refname conflicts between two new references or
between one new reference and any hypothetical old ones.
* It doesn't create reflog entries for the reference creations.
This functionality was implemented in builtin/clone.c. But really that
file shouldn't have such intimate knowledge of how references are
stored. So provide a new function in the refs API,
initial_ref_transaction_commit(), which can be used for initial
reference creation. The new function is based on the ref_transaction
interface.
This means that we can make some other functions private to the refs
module. That will be done in a followup commit.
It would seem to make sense to add a test here that there are no
existing references, because that is how the function *should* be
used. But in fact, the "testgit" remote helper appears to call it
*after* having set up refs/remotes/<name>/HEAD and
refs/remotes/<name>/master, so we can't be so strict. For now, the
function trusts its caller to only call it when it makes sense. Future
commits will add some more limited sanity checks.

The old version just looped over the references to delete, calling
delete_ref() on each one. But that has quadratic behavior, because
each call to delete_ref() might have to rewrite the packed-refs file.
This can be very expensive in a repository with a large number of
references. In some (admittedly extreme) repositories, we've seen
cases where the ref-pruning part of fetch takes multiple tens of
minutes.
Instead call delete_refs(), which (aside from being less code) has the
optimization that it only rewrites the packed-refs file a single time.

This slightly changes how errors are reported. The old and new code
both report errors that come from repack_without_refs() the same way.
But if an error occurs within delete_ref(), the old version only
emitted an error within delete_ref() without further comment. The new
version (in delete_refs()) still emits that error, but then follows it
up with
error(_("could not remove reference %s"), refname)
The "could not remove reference" error originally came from a similar
message in remove_branches() (from builtin/remote.c).
This is an improvement, because the error from delete_ref() (which
usually comes from ref_transaction_commit()) can be pretty low-level,
like
Cannot lock ref '%s': unable to resolve reference %s: %s
where the last "%s" is the original strerror.
In any case, I don't think we need to sweat the details too much,
because these errors should only ever be seen in the case of a broken
repository or a race between two processes; i.e., only in pretty rare
and anomalous situations.

Instead of specifying whether a message by the fsck machinery constitutes
an error or a warning, let's specify an identifier relating to the
concrete problem that was encountered. This is necessary for upcoming
support to be able to demote certain errors to warnings.
In the process, simplify the requirements on the calling code: instead of
having to handle full-blown varargs in every callback, we now send a
string buffer ready to be used by the callback.
We could use a simple enum for the message IDs here, but we want to
guarantee that the enum values are associated with the appropriate
message types (i.e. error or warning?). Besides, we want to introduce a
parser in the next commit that maps the string representation to the
enum value, hence we use the slightly ugly preprocessor construct that
is extensible for use with said parser.

Since cd67e4d (Teach 'git pull' about --rebase, 2007-11-28), if the
--rebase option is set, git-rebase is run instead of git-merge.
Re-implement this by introducing run_rebase(), which is called instead
of run_merge() if opt_rebase is a true value.
Since c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), git-pull handles the case where the upstream
branch was rebased since it was last fetched. The fork point (old remote
ref) of the branch from the upstream branch is calculated before fetch,
and then rebased from onto the new remote head (merge_head) after fetch.
Re-implement this by introducing get_merge_branch_2() and
get_merge_branch_1() to find the upstream branch for the
specified/current branch, and get_rebase_fork_point() which will find
the fork point between the upstream branch and current branch.
However, the above change created a problem where git-rebase cannot
detect commits that are already upstream, and thus may result in
unnecessary conflicts. cf65426 (pull --rebase: Avoid spurious conflicts
and reapplying unnecessary patches, 2010-08-12) fixes this by ignoring
the above old remote ref if it is contained within the merge base of the
merge head and the current branch.
This is re-implemented in run_rebase() where fork_point is not used if
it is the merge base returned by get_octopus_merge_base().

the different cases where git-fetch will not have anything marked for
merge:
1. We fetched from a specific remote, and a refspec was given, but it
ended up not fetching anything. This is usually because the user
provided a wildcard refspec which had no matches on the remote end.
2. We fetched from a non-default remote, but didn't specify a branch to
merge. We can't use the configured one because it applies to the
default remote, and thus the user must specify the branches to merge.
3. We fetched from the branch's or repo's default remote, but:
a. We are not on a branch, so there will never be a configured branch
to merge with.
b. We are on a branch, but there is no configured branch to merge
with.
4. We fetched from the branch's or repo's default remote, but the
configured branch to merge didn't get fetched (either it doesn't
exist, or wasn't part of the configured fetch refspec)
Re-implement the above behavior by implementing get_merge_heads() to
parse the heads in FETCH_HEAD for merging, and implementing
die_no_merge_candidates(), which will be called when FETCH_HEAD has no
heads for merging.

"git clean" uses resolve_gitlink_ref() to check for the presence of
nested git repositories, but it has the drawback of creating a
ref_cache entry for every directory that should potentially be
cleaned. The linear search through the ref_cache list causes a massive
performance hit for large number of directories.
Modify clean.c:remove_dirs to use setup.c:is_git_directory and
setup.c:read_gitfile_gently instead.
Both these functions will open files and parse contents when they find
something that looks like a git repository. This is ok from a
performance standpoint since finding repository candidates should be
comparatively rare.
Using is_git_directory and read_gitfile_gently should give a more
standardized check for what is and what isn't a git repository but
also gives three behavioral changes.
The first change is that we will now detect and avoid cleaning empty
nested git repositories (only init run). This is desirable.
Second, we will no longer die when cleaning a file named ".git" with
garbage content (it will be cleaned instead). This is also desirable.
The last change is that we will detect and avoid cleaning empty bare
repositories that have been placed in a directory named ".git". This
is not desirable but should have no real user impact since we already
fail to clean non-empty bare repositories in the same scenario. This
is thus deemed acceptable.
On top of this we add some extra precautions. If read_gitfile_gently
fails to open the git file, read the git file or verify the path in
the git file we assume that the path with the git file is a valid
repository and avoid cleaning.
Update t7300 to reflect these changes in behavior.

Extract two helper functions out of grab_single_ref(). Firstly,
new_refinfo() which is used to allocate memory for a new refinfo
structure and copy the objectname, refname and flag to it.
Secondly, match_name_as_path() which when given an array of patterns
and the refname checks if the refname matches any of the patterns
given while the pattern is a pathname, also supports wildcard
characters.
This is a preperatory patch for restructuring 'for-each-ref' and
eventually moving most of it to 'ref-filter' to provide the
functionality to similar commands via public API's.

It can be useful to have grafts or replace refs for specific use-cases while
keeping the default "view" of the repository pristine (or with a different
set of grafts/replace refs).
It is possible to use a different graft file with GIT_GRAFT_FILE, but while
replace refs are more powerful, they don't have an equivalent override.

going to look for replace refs.

Since 45e8a74 (has_sha1_file: re-check pack directory before
giving up, 2013-08-30), we spend extra effort for
has_sha1_file to give the right answer when somebody else is
repacking. Usually this effort does not matter, because
after finding that the object does not exist, the next step
is usually to die().
However, some code paths make a large number of
has_sha1_file checks which are _not_ expected to return 1.
The collision test in index-pack.c is such a case. On a
local system, this can cause a performance slowdown of
around 5%. But on a system with high-latency system calls
(like NFS), it can be much worse.
This patch introduces a "quick" flag to has_sha1_file which
callers can use when they would prefer high performance at
the cost of false negatives during repacks. There may be
other code paths that can use this, but the index-pack one
is the most obviously critical, so we'll start with
switching that one.

Commit c6458e6 (index-pack: kill union delta_base to save
memory, 2015-04-18) refactored the comparison functions used
in sorting and binary searching our delta list. The
resulting code does something like:
int cmp_offsets(off_t a, off_t b)
{
return a - b;
}
This works most of the time, but produces nonsensical
results when the difference between the two offsets is
larger than what can be stored in an "int". This can lead to
unresolved deltas if the packsize is larger than 2G (even on
64-bit systems, an int is still typically 32 bits):

If there is a loose reference file with invalid contents, "git
for-each-ref" incorrectly reports the problem as being a missing
object with name NULL_SHA1:
$ echo '12345678' >.git/refs/heads/nonsense
$ git for-each-ref
fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/nonsense
With an explicit "--format" string, it can even report that the
reference validly points at NULL_SHA1:
$ git for-each-ref --format='%(objectname) %(refname)'
0000000000000000000000000000000000000000 refs/heads/nonsense
$ echo $?
0
This has been broken since
b7dd2d2 for-each-ref: Do not lookup objects when they will not be used (2009-05-27)
, which changed for-each-ref from using for_each_ref() to using
git_for_each_rawref() in order to avoid looking up the referred-to
objects unnecessarily. (When "git for-each-ref" is given a "--format"
string that doesn't include information about the pointed-to object,
it does not look up the object at all, which makes it considerably
faster. Iterating with DO_FOR_EACH_INCLUDE_BROKEN is essential to this
optimization because otherwise for_each_ref() would itself need to
check whether the object exists as part of its brokenness test.)
But for_each_rawref() includes broken references in the iteration, and
"git for-each-ref" doesn't itself reject references with REF_ISBROKEN.
The result is that broken references are processed *as if* they had
the value NULL_SHA1, which is the value stored in entries for broken
references.
Change "git for-each-ref" to emit warnings for references that are
REF_ISBROKEN but to otherwise skip them.

"git format-patch --ignore-if-in-upstream A..B", when either A or B
is a tag, failed miserably.
This is because the code passes the tips it used for traversal to
clear_commit_marks(), after running a temporary revision traversal
to enumerate the commits on both branches to find if they have
commits that make equivalent changes. The revision traversal
machinery knows how to enumerate commits reachable starting from a
tag, but clear_commit_marks() wants to take nothing but a commit.
In the longer term, it might be a more correct fix to teach
clear_commit_marks() to do the same "committish to commit"
dereferencing that is done in the revision traversal machinery,
but for now this fix should suffice.

Change typedef each_ref_fn to take a "const struct object_id *oid"
parameter instead of "const unsigned char *sha1".
To aid this transition, implement an adapter that can be used to wrap
old-style functions matching the old typedef, which is now called
"each_ref_sha1_fn"), and make such functions callable via the new
interface. This requires the old function and its cb_data to be
wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be
used as the cb_data for an adapter function, each_ref_fn_adapter().
This is an enormous diff, but most of it consists of simple,
mechanical changes to the sites that call any of the "for_each_ref"
family of functions. Subsequent to this change, the call sites can be
rewritten one by one to use the new interface.

After calling stat_tracking_info, callers often want to
print the name of the upstream branch (in addition to the
tracking count). To do this, they have to access
branch->merge->dst[0] themselves. This is not wrong, as the
return value from stat_tracking_info tells us whether we
have an upstream branch or not. But it is a bit leaky, as we
make an assumption about how it calculated the upstream
name.
Instead, let's add an out-parameter that lets the caller
know the upstream name we found.
As a bonus, we can get rid of the unusual tri-state return
from the function. We no longer need to use it to
differentiate between "no tracking config" and "tracking ref
does not exist" (since you can check the upstream_name for
that), so we can just use the usual 0/-1 convention for
success/error.

When the previous commit introduced the branch_get_upstream
helper, there was one call-site that could not be converted:
the one in sha1_name.c, which gives detailed error messages
for each possible failure.
Let's teach the helper to optionally report these specific
errors. This lets us convert another callsite, and means we
can use the helper in other locations that want to give the
same error messages.
The logic and error messages come straight from sha1_name.c,
with the exception that we start each error with a lowercase

All of the information needed to find the @{upstream} of a
branch is included in the branch struct, but callers have to
navigate a series of possible-NULL values to get there.

When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:
1. git-merge, which uses it to notice when the branch does
not have a remote defined. But we can easily replace this
with looking at remote_name instead.
2. remote.c itself, when setting up the @{upstream} merge
config. But we don't need to save the "remote" in the
"struct branch" for that; we can just look it up for
the duration of the operation.
So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).
So which one do we keep and which one do we get rid of?
If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.
And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

Commit 2879bc3 made the progress and verbosity options sent to remote helper

commit 2879bc3 broke changing progress and verbosity for clone, for urls
requiring a remote helper only (so, not git:// urls, for instance).

This change will also be useful when marking the message for

so it is less fussy for translators to translate without lines running
together in the translated output.
While we're here, start the error messages with a lowercase letter to

A typical setup under Windows is to set core.eol to CRLF, and text
files are marked as "text" in .gitattributes, or core.autocrlf is
set to true.
After 4d4813a5 "git blame" no longer works as expected for such a
set-up. Every line is annotated as "Not Committed Yet", even though
the working directory is clean. This is because the commit removed
the conversion in blame.c for all files, with or without CRLF in the
repo.
Having files with CRLF in the repo and core.autocrlf=input is a
temporary situation, and the files, if committed as is, will be
normalized in the repo, which _will_ be a notable change. Blaming
them with "Not Committed Yet" is the right result. Revert commit
4d4813a5 which was a misguided attempt to "solve" a non-problem.

We had this in "git merge" manual for eternity:
'git merge' <msg> HEAD <commit>...
[This] syntax (<msg> `HEAD` <commit>...) is supported for
historical reasons. Do not use it from the command line or in
new scripts. It is the same as `git merge -m <msg> <commit>...`.
With the update to "git merge" to make it understand what is
recorded in FETCH_HEAD directly, including Octopus merge cases, we
now can rewrite the use of this syntax in "git pull" with a simple
"git merge FETCH_HEAD".
Also there are quite a few fallouts in the test scripts, and it
turns out that "git cvsimport" also uses this old syntax to record
a merge.
Judging from this result, I would not be surprised if dropping the
support of the old syntax broke scripts people have written and been
relying on for the past ten years. But at least we can start the
deprecation process by throwing a warning message when the syntax is
used.
With luck, we might be able to drop the support in a few years.

The collect_parents() function now is responsible for
1. parsing the commits given on the command line into a list of
commits to be merged;
2. filtering these parents into independent ones; and
3. optionally calling fmt_merge_msg() via prepare_merge_message()
to prepare an auto-generated merge log message, using fake
contents that FETCH_HEAD would have had if these commits were
fetched from the current repository with "git pull . $args..."
Make "git merge FETCH_HEAD" to be the same as the traditional
git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits
invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:
- noticing "FETCH_HEAD" is the only "commit" on the command line
and picking the commits that are not marked as not-for-merge as
the list of commits to be merged (substitute for step #1 above);
- letting the resulting list fed to step #2 above;
- doing the step #3 above, using the contents of the FETCH_HEAD
instead of fake contents crafted from the list of commits parsed
in the step #1 above.
Note that this changes the semantics. "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz". With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run. This is a deliberate change to make that happen, and
can be seen in the changes to t3033 tests.

Clarify this small function in three ways.
- The function initially collects all commits to be merged into a
commit_list "remoteheads"; the "remotes" pointer always points at
the tail of this list (either the remoteheads variable itself, or
the ->next slot of the element at the end of the list) to help
elongate the list by repeated calls to commit_list_insert().
Because the new element appended by commit_list_insert() will
always have its ->next slot NULLed out, there is no need for us
to assign NULL to *remotes to terminate the list at the end.
- The variable "head_subsumed" always confused me every time I read
this code. What is happening here is that we inspect what the
caller told us to merge (including the current HEAD) and come up
with the list of parents to be recorded for the resulting merge
commit, omitting commits that are ancestor of other commits.
This filtering may remove the current HEAD from the resulting
parent list---and we signal that fact with this variable, so that
we can later record it as the first parent when "--no-ff" is in
effect.
- The "parents" list is created for this function by reduce_heads()
and was not deallocated after its use, even though the loop
control was written in such a way to allow us to do so by taking
the "next" element in a separate variable so that it can be used
in the next-step part of the loop control.

Once we know the number of objects in the input pack, we allocate an
array of nr_objects of struct delta_entry. On x86-64, this struct is
32 bytes long. The union delta_base, which is part of struct
delta_entry, provides enough space to store either ofs-delta (8 bytes)
or ref-delta (20 bytes).
Because ofs-delta encoding is more efficient space-wise and more
performant at runtime than ref-delta encoding, Git packers try to use
ofs-delta whenever possible, and it is expected that objects encoded
as ref-delta are minority.
In the best clone case where no ref-delta object is present, we waste
(20-8) * nr_objects bytes because of this union. That's about 38MB out
of 100MB for deltas[] with 3.4M objects, or 38%. deltas[] would be
around 62MB without the waste.
This patch attempts to eliminate that. deltas[] array is split into
two: one for ofs-delta and one for ref-delta. Many functions are also
duplicated because of this split. With this patch, ofs_deltas[] array
takes 51MB. ref_deltas[] should remain unallocated in clone case (0
bytes). This array grows as we see ref-delta. We save about half in
this case, or 25% of total bookkeeping.
The saving is more than the calculation above because some padding in
the old delta_entry struct is removed. ofs_delta_entry is 16 bytes,
including the 4 bytes padding. That's 13MB for padding, but packing
the struct could break platforms that do not support unaligned
access. If someone on 32-bit is really low on memory and only deals
with packs smaller than 2G, using 32-bit off_t would eliminate the
padding and save 27MB on top.
A note about ofs_deltas allocation. We could use ref_deltas memory
allocation strategy for ofs_deltas. But that probably just adds more
overhead on top. ofs-deltas are generally the majority (1/2 to 2/3) in
any pack. Incremental realloc may lead to too many memcpy. And if we
preallocate, say 1/2 or 2/3 of nr_objects initially, the growth rate
of ALLOC_GROW() could make this array larger than nr_objects, wasting
more memory.

This reverts commit 2bf15a3330, whose

Originally reported by Bryan Turner; it is too early to declare what

This makes "git merge --quiet" really quiet when we call
into merge-recursive.
Note that we can't just pass our flag down as-is; the two
parts of the code use different scales. We center at "0" as
normal for git-merge (with "--quiet" giving a negative
value), but merge-recursive uses "2" as its center. This
patch passes a negative value to merge-recursive rather than
"1", though, as otherwise the user would have to use "-qqq"
to squelch all messages (but the downside is that the user
cannot distinguish between levels 0-2 if without resorting
to the GIT_MERGE_VERBOSITY variable).
We may want to review and renormalize the message severities
in merge-recursive, but that does not have to happen now.
This is at least in improvement in the sense that we are
respecting "--quiet" at all.

If you create a git repository in the root directory with
"git init /", we erroneously write a core.worktree entry.
This isn't _wrong_, in the sense that it's OK to set
core.worktree when we don't need to. But it is unnecessarily
surprising if you later move the .git directory to another
path (which usually moves the relative working tree, but is
foiled if there is an explicit worktree set).
The problem is that we check whether core.worktree is
necessary by seeing if we can make the git_dir by
concatenating "/.git" onto the working tree. That would lead
to "//.git" in this instance, but we actually have "/.git"
(without the doubled slash).
We can fix this by special-casing the root directory. I also
split the logic out into its own function to make the
conditional a bit more readable (and used skip_prefix, which
I think makes it a little more obvious what is going on).
No tests, as we would need to be able to write to "/" to do
so. I did manually confirm that:
sudo git init /
cd /
git rev-parse --show-toplevel
git config core.worktree
still finds the top-level correctly (as "/"), and does not
set any core.worktree variable.

The code that drives push-to-checkout hook needs no change, as the

"git show-branch --topics <rev> <revs>..." displays ancestry graph, only
considering commits that are in all given revs, except the first one.
"git show-branch" displays ancestry graph for all local branches.
Unfortunately, "git show-branch --topics <rev>" only prints out the rev
info for the given rev, and nothing else, e.g.:
$ git show-branch --topics origin/master
[origin/master] Sync with 2.3.3
While there is an option to add all remote-tracking branches (-r), and
another to add all local+remote branches (-a), there is no option to add
only local branches. Adding such an option could be considered, but a
user would likely already expect that the above command line considers
the lack of rev other than for --topics as meaning all local branches,
like when there is no argument at all.
Moreover, when using -r and -a along with --topics, the first local or
remote-tracking branch, depending on alphabetic order is used instead of
the one given after --topics (any rev given on the command line is
actually simply ignored when either -r or -a is given). And if no rev is
given at all, the fact that the first alphetical branch is the base of
topics is probably not expected by users (Maybe --topics should always
require one rev on the command line?)
This change makes
"show-branch --topics $rev"
act as
"show-branch --topics $rev $(git for-each-ref refs/heads

"show-branch -r --topics $rev ..."

When we find an object in a packfile index, we make sure we
can still open the packfile itself (or that it is already
open), as it might have been deleted by a simultaneous
repack. If we can't access the packfile, we print a warning
for the user and tell the caller that we don't have the
object (we can then look in other packfiles, or find a loose
version, before giving up).
The warning we print to the user isn't really accomplishing
anything, and it is potentially confusing to users. In the
normal case, it is complete noise; we find the object
elsewhere, and the user does not have to care that we racily
saw a packfile index that became stale. It didn't affect the
operation at all.
A possibly more interesting case is when we later can't find
the object, and report failure to the user. In this case the
warning could be considered a clue toward that ultimate
failure. But it's not really a useful clue in practice. We
wouldn't even print it consistently (since we are racing
with another process, we might not even see the .idx file,
or we might win the race and open the packfile, completing
the operation).
This patch drops the warning entirely (not only from the
fill_pack_entry site, but also from an identical use in
pack-objects). If we did find the warning interesting in the
error case, we could stuff it away and reveal it to the user
when we later die() due to the broken object. But that
complexity just isn't worth it.

The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".
Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement. ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.
Move it to dir.c where match_pathspec() is defined.

Entries added by "git add -N" are reminder for the user so that they
don't forget to add them before committing. These entries appear in
the index even though they are not real. Their presence in the index
leads to a confusing "git status" like this:
On branch master
Changes to be committed:
new file: foo
Changes not staged for commit:
modified: foo
If you do a "git commit", "foo" will not be included even though
"status" reports it as "to be committed". This patch changes the
output to become
On branch master
Changes not staged for commit:
new file: foo
no changes added to commit
The two hunks in diff-lib.c adjust "diff-index" and "diff-files" so
that i-t-a entries appear as new files in diff-files and nothing in
diff-index.
Due to this change, diff-files may start to report "new files" for the
first time. "add -u" needs to be told about this or it will die in
denial, screaming "new files can't exist! Reality is wrong." Luckily,
it's the only one among run_diff_files() callers that needs fixing.
Now in the new world order, a hierarchy in the index that contain
i-t-a paths is written out as a tree object as if these i-t-a
entries do not exist, and comparing the index with such a tree
object that would result from writing out the hierarchy will result
in no difference. Update a test in t2203 that expected the i-t-a
entries to appear as "added to the index" in the comparison to
instead expect no output.
An earlier change eec3e7e4 (cache-tree: invalidate i-t-a paths after
generating trees, 2012-12-16) becomes an unnecessary pessimization
in the new world order---a cache-tree in the index that corresponds
to a hierarchy with i-t-a paths can now be marked as valid and
record the object name of the tree that results from writing a tree
object out of that hierarchy, as it will compare equal to that tree.
Reverting the commit is left for the future, though, as it is purely
a performance issue and no longer affects correctness.

Prune should know about broken objects at the tips of refs,
so that we can feed them to our traversal rather than
ignoring them. It's better for us to abort the operation on
the broken object than it is to start deleting objects with
an incomplete view of the reachability namespace.
Note that for missing objects, aborting is the best we can
do. For a badly-named ref, we technically could use its sha1
as a reachability tip. However, the iteration code just
feeds us a null sha1, so there would be a reasonable amount
of code involved to pass down our wishes. It's not really
worth trying to do better, because this is a case that
should happen extremely rarely, and the message we provide:

If clone fails, we generally try to clean up any directories
we've created. We do this by installing an atexit handler,
so that we don't have to manually trigger cleanup. However,
since we install this after touching the filesystem, any
errors between our initial mkdir() and our atexit() call
will result in us leaving a crufty directory around.
We can fix this by moving our atexit() call earlier. It's OK
to do it before the junk_work_tree variable is set, because
remove_junk makes sure the variable is initialized. This
means we "activate" the handler by assigning to the
junk_work_tree variable, which we now bump down to just
after we call mkdir(). We probably do not want to do it
before, because a plausible reason for mkdir() to fail is
EEXIST (i.e., we are racing with another "git init"), and we
would not want to remove their work.
OTOH, this is probably not that big a deal; we will allow
cloning into an empty directory (and skip the mkdir), which
is already racy (i.e., one clone may see the other's empty
dir and start writing into it). Still, it does not hurt to
err on the side of caution here.
Note that writing into junk_work_tree and junk_git_dir after
installing the handler is also technically racy, as we call
our handler on an async signal. Depending on the platform,
we could see a sheared write to the variables. Traditionally
we have not worried about this, and indeed we already do
this later in the function. If we want to address that, it
can come as a separate topic.

If the user enables untracked cache, then

- or simply upgrade OS
- or move the whole (portable) disk from one machine to another

there's no guarantee that untracked cache can still function properly.
Record the worktree location and OS footprint in the cache. If it
changes, err on the safe side and disable the cache. The user can
'update-index --untracked-cache' again to make sure all conditions are

This adds a new requirement that setup_git_directory* must be called

For each object in the input pack, we need one struct object_entry. On
x86-64, this struct is 64 bytes long. Although:
- The 8 bytes for delta_depth and base_object_no are only useful when
show_stat is set. And it's never set unless someone is debugging.
- The three fields hdr_size, type and real_type take 4 bytes each
even though they never use more than 4 bits.
By moving delta_depth and base_object_no out of struct object_entry
and make the other 3 fields one byte long instead of 4, we shrink 25%
of this struct.
On a 3.4M object repo (*) that's about 53MB. The saving is less
impressive compared to index-pack memory use for basic bookkeeping (**),
about 16%.
(*) linux-2.6.git already has 4M objects as of v3.19-rc7 so this is
not an unrealistic number of objects that we have to deal with.

If NULL is passed to ref_transaction_update()'s new_sha1 parameter,
then just verify old_sha1 (under lock) without trying to change the
new value of the reference.
Use this functionality to add a new function ref_transaction_verify(),
which checks the current value of the reference under lock but doesn't
change it.
Use ref_transaction_verify() in the implementation of "git update-ref
--stdin"'s "verify" command to avoid the awkward need to "update" the
reference to its existing value.

This will let us manipulate any transport flags which have matching

the next patch).
We could also just make "flags" a static file-scope global,
but the result is a little confusing. We end up passing it
along through do_push and push_with_options, each of which
further munge it. Having slightly-differing versions of the
flags variable available to those functions would probably
cause more confusion than it is worth. Let's just keep the
original local to cmd_push, and it can continue to pass it
through the call-stack.

Because Git tracks symbolic links as symbolic links, a path that
has a symbolic link in its leading part (e.g. path/to/dir/file,
where path/to/dir is a symbolic link to somewhere else, be it
inside or outside the working tree) can never appear in a patch
that validly applies, unless the same patch first removes the
symbolic link to allow a directory to be created there.
Detect and reject such a patch.
Things to note:
- Unfortunately, we cannot reuse the has_symlink_leading_path()
from dir.c, as that is only about the working tree, but "git
apply" can be told to apply the patch only to the index or to
both the index and to the working tree.
- We cannot directly use has_symlink_leading_path() even when we
are applying only to the working tree, as an early patch of a
valid input may remove a symbolic link path/to/dir and then a
later patch of the input may create a path path/to/dir/file, but
"git apply" first checks the input without touching either the
index or the working tree. The leading symbolic link check must
be done on the interim result we compute in-core (i.e. after the
first patch, there is no path/to/dir symbolic link and it is
perfectly valid to create path/to/dir/file).
Similarly, when an input creates a symbolic link path/to/dir and
then creates a file path/to/dir/file, we need to flag it as an
error without actually creating path/to/dir symbolic link in the
filesystem.
Instead, for any patch in the input that leaves a path (i.e. a non
deletion) in the result, we check all leading paths against the
resulting tree that the patch would create by inspecting all the
patches in the input and then the target of patch application
(either the index or the working tree).
This way, we catch a mischief or a mistake to add a symbolic link
path/to/dir and a file path/to/dir/file at the same time, while
allowing a valid patch that removes a symbolic link path/to/dir and
then adds a file path/to/dir/file.

We should reject a patch, whether it renames/copies dir/file to

from a path that is beyond a symbolic link.

We currently read the preimage to apply a patch from the index only
when the --cached option is given. Do so also when the command is
running under the --index option. With --index, the index entry and
the working tree file for a path that is involved in a patch must be
identical, so this should not affect the result, but by reading from
the index, we will get the protection to avoid reading an unintended
path beyond a symbolic link automatically.

By default, a patch that affects outside the working area (either a
Git controlled working tree, or the current working directory when
"git apply" is used as a replacement of GNU patch) is rejected as a
mistake (or a mischief). Git itself does not create such a patch,
unless the user bends over backwards and specifies a non-standard
prefix to "git diff" and friends.
When `git apply` is used as a "better GNU patch", the user can pass
the `--unsafe-paths` option to override this safety check. This
option has no effect when `--index` or `--cached` is in use.
The new test was stolen from Jeff King with slight enhancements.
Note that a few new tests for touching outside the working area by
following a symbolic link are still expected to fail at this step,
but will be fixed in later steps.

When the incoming patch has whitespace errors in a common context
line (i.e. a line that is expected to be found and is not modified

errors the line has, in addition to the whitespace error on a line
that is updated by the patch. However, we did not count and report
that we fixed whitespace errors on such lines.
[jc: This is iffy. What if the whitespace error has been fixed in

see in the patch has errors, and it matches a line in the target
that has the errors already corrected, resulting in no change, which
we may not want to count after all. On the other hand, we are
reporting whitespace errors _in_ the incoming patch, so...]

Under --whitespace=fix option, match_fragment() function examines
the preimage (the common context and the removed lines in the patch)
and the file being patched and checks if they match after correcting
all whitespace errors. When they are found to match, the common
context lines in the preimage is replaced with the fixed copy,
because these lines will then be copied to the corresponding place
in the postimage by a later call to update_pre_post_images(). Lines
that are added in the postimage, under --whitespace=fix, have their
whitespace errors already fixed when apply_one_fragment() prepares
the preimage and the postimage, so in the end, application of the
patch can be done by replacing the block of text in the file being
patched that matched the preimage with what is in the postimage that
was updated by update_pre_post_images().
In the earlier days, fixing whitespace errors always resulted in
reduction of size, either collapsing runs of spaces in the indent to
a tab or removing the trailing whitespaces. These days, however,
some whitespace error fix results in extending the size.
250b3c6c (apply --whitespace=fix: avoid running over the postimage
buffer, 2013-03-22) tried to compute the final postimage size but
its math was flawed. It counted the size of the block of text in
the original being patched after fixing the whitespace errors on its
lines that correspond to the preimage. That number does not have
much to do with how big the final postimage would be.
Instead count (1) the added lines in the postimage, whose size is
the same as in the final patch result because their whitespace
errors have already been corrected, and (2) the fixed size of the
lines that are common.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
"git apply --whitespace=fix" used to be able to assume that fixing
errors will always reduce the size by e.g. stripping whitespaces at
the end of lines or collapsing runs of spaces into tabs at the
beginning of lines. An update to accomodate fixes that lengthens
the result by e.g. expanding leading tabs into spaces were made long
time ago but the logic miscounted the necessary space after such
whitespace fixes, leading to either under-allocation or over-usage
of already allocated space.

future breakage. The test was stolen from Kyle McKay who helped

The code handling %(upstream:track) and %(upstream:trackshort)

earlier in populate_value(), and thus did not check the return value

While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a

spurious values such as

When receive.denyCurrentBranch is set to updateInstead, a push that
tries to update the branch that is currently checked out is accepted
only when the index and the working tree exactly matches the
currently checked out commit, in which case the index and the
working tree are updated to match the pushed commit. Otherwise the
push is refused.
This hook can be used to customize this "push-to-deploy" logic. The
hook receives the commit with which the tip of the current branch is
going to be updated, and can decide what kind of local changes are
acceptable and how to update the index and the working tree to match
the updated tip of the current branch.
For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
in order to emulate 'git fetch' that is run in the reverse direction
with `git push`, as the two-tree form of `read-tree -u -m` is
essentially the same as `git checkout` that switches branches while
keeping the local changes in the working tree that do not interfere
with the difference between the branches.

This adds support to send-pack to negotiate and use atomic pushes
iff the server supports it. Atomic pushes are activated by a new command
line flag --atomic.
In order to do this we also need to change the semantics for send_pack()
slightly. The existing send_pack() function actually doesn't send all the
refs back to the server when multiple refs are involved, for example
when using --all. Several of the failure modes for pushes can already be
detected locally in the send_pack client based on the information from the
initial server side list of all the refs as generated by receive-pack.
Any such refs that we thus know would fail to push are thus pruned from
the list of refs we send to the server to update.
For atomic pushes, we have to deal thus with both failures that are detected
locally as well as failures that are reported back from the server. In order
to do so we treat all local failures as push failures too.
We introduce a new status code REF_STATUS_ATOMIC_PUSH_FAILED so we can
flag all refs that we would normally have tried to push to the server
but we did not due to local failures. This is to improve the error message
back to the end user to flag that "these refs failed to update since the
atomic push operation failed."

Discussion on the previous patch revealed we rather want to err on the
safe side. To do so we need to stop receive-pack in case of the possible
future bug when connectivity is not checked on a shallow push.
Also while touching that code we considered that removing the reported
refs may be harmful in some situations. Sound the message more like a
"This Cannot Happen, Please Investigate!" instead of giving advice to

Make the main "execute_commands" loop in receive-pack easier to read
by splitting out some steps into helper functions. The new helper
'should_process_cmd' checks if a ref update is unnecessary, whether
due to an error having occurred or for another reason. The helper
'warn_if_skipped_connectivity_check' warns if we have forgotten to
run a connectivity check on a ref which is shallow for the client
which would be a bug.
This will help us to duplicate less code in a later patch when we make
a second copy of the "execute_commands" loop.

The parse_options API expects an array of alternative usage lines
to which it automatically ads the language-appropriate "or" when
displaying. Each of these options is marked for translation with N_
and then later translated when gettext is called on each element
of the array.
Since the N_ macro just expands to its argument, if two N_-marked
strings appear next to each other without being separated by anything
else such as a comma, the preprocessor will join them into one string.
In that case two separate strings get marked for translation, but at
runtime they have been joined into a single string passed to gettext
which then fails to get translated because the combined string was
never marked for translation.
Fix this by properly separating the two N_ marked strings with
a comma and removing the embedded "\n" and " or:" that are
properly supplied by the parse_options API.

checkout-index --temp only properly prints relative paths which are
descendants of the current directory. Paths in ancestor or sibling
directories (or their children) are often printed in mangled form. For
example:
mkdir a bbb &&
>file &&
>bbb/file &&
git update-index --add file bbb/file &&
cd a &&
git checkout-index --temp ../file ../bbb/file
prints:
.merge_file_ooblek le
.merge_file_igloo0 b/file
rather than the correct:
.merge_file_ooblek ../file
.merge_file_igloo0 ../bbb/file
Internally, given the above example, checkout-index prefixes each input
argument with the name of the current directory ("a/", in this case),
and then assumes that it can simply skip forward by strlen("a/") bytes
to recover the original name. This works for files in the current
directory or its descendants, but fails for files in ancestors or
siblings (or their children) due to path normalization.
For instance, given "../file", "a/" is prepended, giving "a/../file".
Path normalization folds out "a/../", resulting in "file". Attempting
to recover the original name by skipping strlen("a/") bytes gives the
incorrect "le" rather than the desired "../file".
Fix this by taking advantage of write_name_quoted_relative() to recover
the original name properly, rather than assuming that it can be
recovered by skipping strlen(prefix) bytes.
As a bonus, this also fixes a bug in which checkout-index --temp
accessed and printed memory beyond the end-of-string. For instance,
within a subdirectory named "subdirectory", and given argument
"../file", prefixing would give "subdirectory/../file", which would
become "file" after normalization. checkout-index would then attempt to
recover the original name by skipping strlen("subdirectory/") bytes of
"file", which placed it well beyond end-of-string. Despite this error,
it often appeared to give the correct result, but only due to an
accident of implementation which left an apparently correct copy of the
path in memory following the normalized value. In particular, handed
"subdirectory/../file", in-place processing by normalize_path_copy_len()
resulted in "file\0rectory/../file". When checkout-index skipped
strlen("subdirectory/") bytes, it ended up back at "../file" and thus
appeared to give the correct answer, despite being past end-of-string.

When fetching into or pushing from a shallow repository, we want to
aggressively mark edges as uninteresting, since this decreases the pack
size. However, aggressively marking edges can negatively affect
performance on large non-shallow repositories with lots of refs.
Teach pack-objects a --shallow option to indicate that we're pushing
from or fetching into a shallow repository. Use
--objects-edge-aggressive only for shallow repositories and otherwise
use --objects-edge, which performs better in the general case. Update

smaller packs for shallow clones.
Unfortunately, they cause a significant performance regression when
pushing non-shallow clones with lots of refs (23.322 seconds vs.
4.785 seconds with 22400 refs). Add an option to git rev-list,

To figure out the author ident for a commit, we call
determine_author_info(). This function collects information
from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then
uses fmt_ident to generate the final ident string that goes
into the commit object. fmt_ident is therefore responsible
for any quality or validation checks on what is allowed to
go into a commit.
Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field). If this parsing or validation fails, we skip
updating the environment variables.
This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).
If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.
Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.
When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational. Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.
We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).
In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.
We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.
Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.
So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

Non-recursive checkout creates empty directpries in place of submodules.
If then I try to "checkout --to" submodules there, it refuses to do so,
because directory already exists.
Fix by allowing checking out to empty directory. Add test and modify the
existing one so that it uses non-empty directory.

For normal use cases, it does not make sense for 'checkout' to work on
a bare repository, without a worktree. But "checkout --to" is an
exception because it _creates_ a new worktree. Allow this option to
run on bare repositories.
People who check out from a bare repository should remember that
core.logallrefupdates is off by default and it should be turned back
on. `--to` cannot do this automatically behind the user's back because
some user may deliberately want no reflog.
For people interested in repository setup/discovery code,
is_bare_repository_cfg (aka "core.bare") is unchanged by this patch,
which means 'true' by default for bare repos. Fortunately when we get
the repo through a linked checkout, is_bare_repository_cfg is never
used. So all is still good.

One branch obviously can't be checked out at two places (but detached
heads are ok). Give the user a choice in this case: --detach, -b
new-branch, switch branch in the other checkout first or simply 'cd'
and continue to work there.

(alias R=$GIT_COMMON_DIR/worktrees/<id>)
- linked checkouts are supposed to keep its location in $R/gitdir up
to date. The use case is auto fixup after a manual checkout move.
- linked checkouts are supposed to update mtime of $R/gitdir. If
$R/gitdir's mtime is older than a limit, and it points to nowhere,
worktrees/<id> is to be pruned.
- If $R/locked exists, worktrees/<id> is not supposed to be pruned. If
$R/locked exists and $R/gitdir's mtime is older than a really long
limit, warn about old unused repo.
- "git checkout --to" is supposed to make a hard link named $R/link
pointing to the .git file on supported file systems to help detect
the user manually deleting the checkout. If $R/link exists and its
link count is greated than 1, the repo is kept.

"git checkout --to" sets up a new working directory with a .git file
pointing to $GIT_DIR/worktrees/<id>. It then executes "git checkout"
again on the new worktree with the same arguments except "--to" is
taken out. The second checkout execution, which is not contaminated
with any info from the current repository, will actually check out and
everything that normal "git checkout" does.

The repo setup procedure is updated to detect $GIT_DIR/commondir and
set $GIT_COMMON_DIR properly.
The core.worktree is ignored when $GIT_COMMON_DIR is set. This is
because the config file is shared in multi-checkout setup, but
checkout directories _are_ different. Making core.worktree effective
in all checkouts mean it's back to a single checkout.

Among pathnames in $GIT_DIR, e.g. "index" or "packed-refs", we want to
automatically and silently map some of them to the $GIT_DIR of the
repository we are borrowing from via $GIT_COMMON_DIR mechanism. When
we formulate the pathname for its lockfile, we want it to be in the
same location as its final destination. "index" is not shared and
needs to remain in the borrowing repository, while "packed-refs" is
shared and needs to go to the borrowed repository.
git_path() could be taught about the ".lock" suffix and map
"index.lock" and "packed-refs.lock" the same way their basenames are
mapped, but instead the caller can help by asking where the basename
(e.g. "index") is mapped to git_path() and then appending ".lock"
after the mapping is done.

We allow the user to relocate certain paths out of $GIT_DIR via
environment variables, e.g. GIT_OBJECT_DIRECTORY, GIT_INDEX_FILE and
GIT_GRAFT_FILE. Callers are not supposed to use git_path() or
git_pathdup() to get those paths. Instead they must use
get_object_directory(), get_index_file() and get_graft_file()
respectively. This is inconvenient and could be missed in review (for
example, there's git_path("objects/info/alternates") somewhere in
sha1_file.c).
This patch makes git_path() and git_pathdup() understand those
environment variables. So if you set GIT_OBJECT_DIRECTORY to /foo/bar,
git_path("objects/abc") should return /foo/bar/abc. The same is done
for the two remaining env variables.
"git rev-parse --git-path" is the wrapper for script use.
This patch kinda reverts a0279e1 (setup_git_env: use git_pathdup
instead of xmalloc + sprintf - 2014-06-19) because using git_pathdup
here would result in infinite recursion:
setup_git_env() -> git_pathdup("objects") -> .. -> adjust_git_path()
-> get_object_directory() -> oops, git_object_directory is NOT set
yet -> setup_git_env()
I wanted to make git_pathdup_literal() that skips adjust_git_path().
But that won't work because later on when $GIT_COMMON_DIR is
introduced, git_pathdup_literal("objects") needs adjust_git_path() to
replace $GIT_DIR with $GIT_COMMON_DIR.

In the previous patch, git_snpath() is modified to allocate a new
strbuf buffer because vsnpath() needs that. But that makes it
awkward because git_snpath() receives a pre-allocated buffer from
outside and has to copy data back. Rename it to strbuf_git_path()
and make it receive strbuf directly.
Using git_path() in update_refs_for_switch() which used to call
git_snpath() is safe because that function and all of its callers do
not keep any pointer to the round-robin buffer pool allocated by
get_pathname().

Before the previous commit, get_pathname returns an array of PATH_MAX
length. Even if git_path() and similar functions does not use the
whole array, git_path() caller can, in theory.
After the commit, get_pathname() may return a buffer that has just
enough room for the returned string and git_path() caller should never
write beyond that.
Make git_path(), mkpath() and git_path_submodule() return a const
buffer to make sure callers do not write in it at all.
This could have been part of the previous commit, but the "const"
conversion is too much distraction from the core changes in path.c.

The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.
When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.
And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.
We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only
check the "simple" behavior itself.

When synchronizing between working directories, it can be handy to update
the current branch via 'push' rather than 'pull', e.g. when pushing a fix
from inside a VM, or when pushing a fix made on a user's machine (where
the developer is not at liberty to install an ssh daemon let alone know
the user's password).
The common workaround – pushing into a temporary branch and then merging
on the other machine – is no longer necessary with this patch.
The new option is:
'updateInstead':
Update the working tree accordingly, but refuse to do so if there
are any uncommitted changes.
