Merges with an absurd number of parents are still a bad idea because
they do not render well in tools like gitk, but if they are present
in the repository being imported into git then there's no need to
avoid reproducing them faithfully.
In olden times, before v1.6.0-rc0~194 (2008-06-27), git commit-tree
and higher-level tools built on top of it were limited to writing 16
parents for a commit. Nowadays normal git operations are happy to
write more parents when asked, so the motivation for this note in the
fast-import documentation is gone and we can remove it.

Ignoring a merge can be read as ignoring the changes a merge commit
introduces altogether, as if the entire side branch the merge commit
merged was removed from the history. But that is not what happens
if "-p" is not specified. What happens is that the individual
commits a merge commit introduces are replayed in order, and only
any possible merge conflict resolutions or manual amendments to the
merge commit are ignored.
Get this straight in the docs.
Also, do not say that merge commits are *tried* to be recreated. As that is
true almost everywhere it is better left unsaid.

Add $XDG_CONFIG_HOME/git/credentials to the default credential search
path of git-credential-store. This allows git-credential-store to
support user-specific configuration files in accordance with the XDG
base directory specification[1].
[1] http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
~/.git-credentials has a higher precedence than
$XDG_CONFIG_HOME/git/credentials when looking up credentials. This
means that if any duplicate matching credentials are found in the xdg
file (due to ~/.git-credentials being updated by old versions of git or
outdated tools), they will not be used at all. This is to give the user
some leeway in switching to old versions of git while keeping the xdg
directory. This is consistent with the behavior of git-config.
However, the higher precedence of ~/.git-credentials means that as long
as ~/.git-credentials exist, all credentials will be written to the
~/.git-credentials file even if the user has an xdg file as having a
~/.git-credentials file indicates that the user wants to preserve
backwards-compatibility. This is also consistent with the behavior of
git-config.
To make this precedence explicit in docs/git-credential-store, add a new
section FILES that lists out the credential file paths in their order of
precedence, and explain how the ordering affects the lookup, storage and
erase operations.
Also, update the documentation for --file to briefly explain the
operations on multiple files if the --file option is not provided.
Since the xdg file will not be used unless it actually exists, to
prevent the situation where some credentials are present in the xdg file
while some are present in the home file, users are recommended to not
create the xdg file if they require compatibility with old versions of
git or outdated tools. Note, though, that "erase" can be used to
explicitly erase matching credentials from all files.

Most operations that iterate over refs are happy to ignore
broken cruft. However, some operations should be performed
with knowledge of these broken refs, because it is better
for the operation to choke on a missing object than it is to
silently pretend that the ref did not exist (e.g., if we are
computing the set of reachable tips in order to prune
objects).
These processes could just call for_each_rawref, except that
ref iteration is often hidden behind other interfaces. For
instance, for a destructive "repack -ad", we would have to
inform "pack-objects" that we are destructive, and then it
would in turn have to tell the revision code that our
"--all" should include broken refs.
It's much simpler to just set a global for "dangerous"
operations that includes broken refs in all iterations.

If the user enables untracked cache, then
- move worktree to an unsupported filesystem
- or simply upgrade OS
- or move the whole (portable) disk from one machine to another
- or access a shared fs from another machine
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
met.
This adds a new requirement that setup_git_directory* must be called
before read_cache() because we need worktree location by then, or the
cache is dropped.

If we are expiring reflog entries for a symbolic reference, then how
should --updateref be handled if the newest reflog entry is expired?
Option 1: Update the referred-to reference. (This is what the current
code does.) This doesn't make sense, because the referred-to reference
has its own reflog, which hasn't been rewritten.
Option 2: Update the symbolic reference itself (as in, REF_NODEREF).
This would convert the symbolic reference into a non-symbolic
reference (e.g., detaching HEAD), which is surely not what a user
would expect.
Option 3: Error out. This is plausible, but it would make the
following usage impossible:
git reflog expire ... --updateref --all
Option 4: Ignore --updateref for symbolic references.
We choose to implement option 4.

In "git log --decorate", you would see the commit header like this:
commit ... (HEAD, jc/decorate-leaky-separator-color)
where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.
If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say
[color "decorate"]
head = black
branch = black
because that you would not be able to reuse same configuration on a
white-on-black terminal. You would naively expect
[color "decorate"]
head = normal
branch = normal
to work, but unfortunately it does not. It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements. This is because the code
forgets to reset the color after printing the "prefix" in its own
color.
It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

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,

It seems to be a common mistake to try using a single remote
(e.g. 'origin') to fetch from one place (i.e. upstream) while
pushing to another (i.e. your publishing point).
That will never work satisfactorily, and it is easy to understand
why if you think about what refs/remotes/origin/* would mean in such
a world. It fundamentally cannot reflect the reality. If it
follows the state of your upstream, it cannot match what you have
published, and vice versa.
It may be that misinformation is spread by some people. Let's
counter them by adding a few words to our documentation.
- The description was referring to <oldurl> and <newurl>, but never
mentioned <name> argument you give from the command line. By
mentioning "remote <name>", stress the fact that it is configuring
a single remote.
- Add a reminder that explicitly states that this is about a single
remote, which the triangular workflow is not about.

b6d8f309 (diff-raw format update take #2., 2005-05-23) started
documenting the diff format, and it said
...
(8) sha1 for "dst"; 0{40} if creation, unmerged or "look at work tree".
(9) status, followed by similarlity index number only for C and R.
(10) a tab or a NUL when '-z' option is used.
...
because C and R _were_ the only ones that came with a number back
then. This was corrected by ddafa7e9 (diff-helper: Fix R/C score
parsing under -z flag., 2005-05-29) and we started saying "score"
instead of "similarlity index" (because we can have other kind of
score there), and stopped saying "only for C and R" (because Git is
an ever evolving system). Later f345b0a0 (Add -B flag to diff-*
brothers., 2005-05-30) introduced a new concept, "dissimilarity"
score; it did not have to fix any documentation.
The current text that says only C and R can have scores came
independently from a5a323f3 (Add reference for status letters in

Some of strbuf is documented as comments above functions,
and some is separate in Documentation/technical/api-strbuf.txt.
This makes it annoying to find the appropriate documentation.
We'd rather have it all in one place, which means all in the
text document, or all in the header.
Let's choose the header as that place. Even though the
formatting is not quite as pretty, this keeps the
documentation close to the related code. The hope is that
this makes it easier to find what you want (human-readable
comments are right next to the C declarations), and easier
for writers to keep the documentation up to date.
This is more or less a straight import of the text from
api-strbuf.txt into C comments, complete with asciidoc
formatting. The exceptions are:
1. All comments created in this way are started with "/**"
to indicate they are part of the API documentation. This
may help later with extracting the text to pretty-print
it.
2. Function descriptions do not repeat the function name,
as it is available in the context directly below. So:
`strbuf_add`::
Add data of given length to the buffer.
from api-strbuf.txt becomes:
/**
* Add data of given length to the buffer.
*/
void strbuf_add(struct strbuf *sb, const void *, size_t);
As a result, any block-continuation required in asciidoc
for that list item was dropped in favor of straight
blank-line paragraph (since it is not necessary when we
are not in a list item).
3. There is minor re-wording to integrate existing comments
and api-strbuf text. In each case, I took whichever
version was more descriptive, and eliminated any
redundancies. In one case, for strbuf_addstr, the api
documentation gave its inline definition; I eliminated
this as redundant with the actual definition, which can
be seen directly below the comment.
4. The functions in the header file are re-ordered to match
the ordering of the API documentation, under the
assumption that more thought went into the grouping
there.

Even though "advice.h" includes "git-compat-util.h", it is not
sensible to have it as the first #include and indirectly satisify
the "You must give git-compat-util.h a clean environment to set up
feature test macros before including any of the system headers are
included", which is the real requirement.
Because:
- A command that interacts with the object store, config subsystem,
the index, or the working tree cannot do anything without using
what is declared in "cache.h";
- A built-in command must be declared in "builtin.h", so anything
in builtin/*.c must include it;
- These two headers both include "git-compat-util.h" as the first
thing; and
- Almost all our *.c files (outside compat/ and borrowed files in
xdiff/) need some Git-ness from "cache.h" to do something
Git-ish.
let's explicitly specify that one of these three header files must
be the first thing that is included.
Any of our *.c file should include the header file that directly
declares what it uses, instead of relying on the fact that some *.h
file it includes happens to include another *.h file that declares
the necessary function or type. Spell it out as another guideline
item.

"git log --grep=<string>" shows only commits with messages that

show only commits that do *not* have certain messages (e.g. "show

Originally, we had the invert-grep flag in grep_opt, but because
"git grep --invert-grep" does not make sense except in conjunction
with "--files-with-matches", which is already covered by
"--files-without-matches", it was moved it to revisions structure.
To have the flag there expresses the function to the feature better.
When the newly inserted two tests run, the history would have commits
with messages "initial", "second", "third", "fourth", "fifth", "sixth"
and "Second", committed in this order. The commits that does not match
either "th" or "Sec" is "second" and "initial". For the case insensitive

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."

The goal seems to be using multiple checkouts to reduce disk space.
But we have not reached an agreement how things should be. There are a
couple options.
- You may want to keep $SUB repos elsewhere (perhaps in a central
place) outside $SUPER. This is also true for nested submodules
where a superproject may be a submodule of another superproject.
- You may want to keep all $SUB repos in $SUPER/modules (or some
other place in $SUPER)
- We could even push it further and merge all $SUB repos into $SUPER
instead of storing them separately. But that would at least require
ref namespace enabled.
On top of that, git-submodule.sh expects $GIT_DIR/config to be
per-worktree, at least for the submodule.* part. Here I think we have
two options, either update config.c to also read
$GIT_DIR/config.worktree (which is per worktree) in addition to
$GIT_DIR/config (shared) and store worktree-specific vars in the new
place, or update git-submodule.sh to read/write submodule.* directly
from $GIT_DIR/config.submodule (per worktree).
These take time to address properly. Meanwhile, make a note to the
user that they should not use multiple worktrees in submodule context.

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

use --objects-edge, which performs better in the general case. Update

of edges uninteresting. This change, and the subsequent change to make
this conditional on --objects-edge, are used by --thin to make much
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,
--objects-edge-aggressive, that preserves this more aggressive behavior,
