Documentation/i18n.txt: clarify character encoding support
As a "distributed" VCS, git should better define the encodings of its core
textual data structures, in particular those that are part of the network
protocol.
That git is encoding agnostic is only really true for blob objects. E.g.
the 'non-NUL bytes' requirement of tree and commit objects excludes
UTF-16/32, and the special meaning of '/' in the index file as well as
space and linefeed in commit objects eliminates EBCDIC and other non-ASCII
encodings.
Git expects bytes < 0x80 to be pure ASCII, thus CJK encodings that partly
overlap with the ASCII range are problematic as well. E.g. fmt_ident()
removes trailing 0x5C from user names on the assumption that it is ASCII
'\'. However, there are over 200 GBK double byte codes that end in 0x5C.
UTF-8 as default encoding on Linux and respective path translations in the
Mac and Windows versions have established UTF-8 NFC as de-facto standard
for path names.
Update the documentation in i18n.txt to reflect the current status-quo.

rev-list: disable --use-bitmap-index when pruning commits
The reachability bitmaps do not have enough information to
tell us which commits might have changed path "foo", so the
current code produces wrong answers for:
git rev-list --use-bitmap-index --count HEAD -- foo
(it silently ignores the "foo" limiter). Instead, we should
fall back to doing a normal traversal (it is OK to fall
back rather than complain, because --use-bitmap-index is a
pure optimization, and might not kick in for other reasons,
such as there being no bitmaps in the repository).

Add tests for wildcard "path vs ref" disambiguation
Commit 28fcc0b (pathspec: avoid the need of "--" when wildcard is used -
2015-05-02) changes how the disambiguation rules work. This patch adds
some tests to demonstrate, basically, if wildcard characters are in an
argument:
- if the argument is valid extended sha-1 syntax, "--" must be used
- otherwise the argument is considered a path, even without "--"
And wildcard can appear in extended sha-1 syntax, either as part of
regex in ":/<regex>" or as the literal path in ":<path>". The latter
case is less likely to happen in real world. But if you do ":/" a lot,
you may need to type "--" more.

It is sometimes useful for importers to be able to read the SHA-1
corresponding to a mark that they have created via fast-import. For
example, they might want to embed the SHA-1 into the commit message of
a later commit. Or it might be useful for internal bookkeeping uses,
or for logging.
Add a "get-mark" command to "git fast-import" that allows the importer
to ask for the value of a mark that has been created earlier.

git rebase -i: add static check for commands and SHA-1
Check before the start of the rebasing if the commands exists, and for

This allows to avoid doing half of a rebase before finding an error

When rev-list's --cherry option does not detect that a patch has already

consequently stop at that patch with a failure, mentioning that the diff

Traditionally, a `git rebase --continue` simply skips the commit in such a

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.

Commit 23af91d (prune: strategies for linked checkouts - 2014-11-30)
adds "--worktrees" to "git prune" without realizing that "git prune" is
for object database only. This patch moves the same functionality to a
new command "git worktree".
fsck: it is OK for a tag and a commit to lack the body
When fsck validates a commit or a tag, it scans each line in the
header of the object using helper functions such as "start_with()",
etc. that work on a NUL terminated buffer, but before a1e920a0
(index-pack: terminate object buffers with NUL, 2014-12-08), the
validation functions were fed the object data in a piece of memory
that is not necessarily terminated with a NUL.
We added a helper function require_end_of_header() to be called at
the beginning of these validation functions to insist that the
object data contains an empty line before its end. The theory is
that the validating functions will notice and stop when it hits an
empty line as a normal end of header (or a required header line that
is missing) without scanning past the end of potentially not
NUL-terminated buffer.
But the theory forgot that in the older days, Git itself happily
created objects with only the header lines without a body. This
caused Git 2.2 and later to issue an unnecessary warning in some
existing repositories.
With a1e920a0, we do not need to require an empty line (or the body)
in these objects to safely parse and validate them. Drop the
offending "must have an empty line" check from this helper function,
while keeping the other check to make sure that there is no NUL in
the header part of the object, and adjust the name of the helper to
what it does accordingly.

When ac49f5ca (rerere "remaining", 2011-02-16) split out a new
helper function check_one_conflict() out of find_conflict()
function, so that the latter will use the returned value from the
new helper to update the loop control variable that is an index into
active_cache[], the new variable incremented the index by one too
many when it found a path with only stage #1 entry at the very end
of active_cache[].
This "strange" return value does not have any effect on the loop
control of two callers of this function, as they all notice that
active_nr+2 is larger than active_nr just like active_nr+1 is, but
nevertheless it puzzles the readers when they are trying to figure
out what the function is trying to do.
In fact, there is no need to do an early return. The code that
follows after skipping the stage #1 entry is fully prepared to
handle a case where the entry is at the very end of active_cache[].
Help future readers from unnecessary confusion by dropping an early
return. We skip the stage #1 entry, and if there are stage #2 and
stage #3 entries for the same path, we diagnose the path as
THREE_STAGED (otherwise we say PUNTED), and then we skip all entries
for the same path.

* Beef up the "Description" section.
* Make the first long example less specific to kernel development.

setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR
In the test case, we run setup_git_dir_gently() the first time to read
$GIT_DIR/config so that we can resolve aliases. We'll enter
setup_discovered_git_dir() and may or may not call set_git_dir() near
the end of the function, depending on whether the detected git dir is
".git" or not. This set_git_dir() will set env var $GIT_DIR.
For normal repo, git dir detected via setup_discovered_git_dir() will be
".git", and set_git_dir() is not called. If .git file is used however,
the git dir can't be ".git" and set_git_dir() is called and $GIT_DIR
set. This is the key of this problem.
If we expand an alias (or autocorrect command names), then
setup_git_dir_gently() is run the second time. If $GIT_DIR is not set in
the first run, we run the same setup_discovered_git_dir() as before.
Nothing to see. If it is, however, we'll enter setup_explicit_git_dir()
this time.
This is where the "fun" is. If $GIT_WORK_TREE is not set but
$GIT_DIR is, you are supposed to be at the root level of the
worktree. But if you are in a subdir "foo/bar" (real worktree's top
is "foo"), this rule bites you: your detected worktree is now
"foo/bar", even though the first run correctly detected worktree as
"foo". You get "internal error: work tree has already been set" as a
result.
Bottom line is, when $GIT_DIR is set, $GIT_WORK_TREE should be set too
unless there's no work tree. But setting $GIT_WORK_TREE inside
set_git_dir() may backfire. We don't know at that point if work tree is
already configured by the caller. So set it when work tree is
detected. It does not harm if $GIT_WORK_TREE is set while $GIT_DIR is
not.

introduce "extensions" form of core.repositoryformatversion
Normally we try to avoid bumps of the whole-repository
core.repositoryformatversion field. However, it is
unavoidable if we want to safely change certain aspects of
git in a backwards-incompatible way (e.g., modifying the set
of ref tips that we must traverse to generate a list of
unreachable, safe-to-prune objects).
If we were to bump the repository version for every such
change, then any implementation understanding version `X`
would also have to understand `X-1`, `X-2`, and so forth,
even though the incompatibilities may be in orthogonal parts
of the system, and there is otherwise no reason we cannot
implement one without the other (or more importantly, that
the user cannot choose to use one feature without the other,
weighing the tradeoff in compatibility only for that
particular feature).
This patch documents the existing repositoryformatversion
strategy and introduces a new format, "1", which lets a
repository specify that it must run with an arbitrary set of
extensions. This can be used, for example:
- to inform git that the objects should not be pruned based
only on the reachability of the ref tips (e.g, because it
has "clone --shared" children)
- that the refs are stored in a format besides the usual
"refs" and "packed-refs" directories
Because we bump to format "1", and because format "1"
requires that a running git knows about any extensions
mentioned, we know that older versions of the code will not
do something dangerous when confronted with these new
formats.
For example, if the user chooses to use database storage for
refs, they may set the "extensions.refbackend" config to
"db". Older versions of git will not understand format "1"
and bail. Versions of git which understand "1" but do not
know about "refbackend", or which know about "refbackend"
but not about the "db" backend, will refuse to run. This is
annoying, of course, but much better than the alternative of
claiming that there are no refs in the repository, or
writing to a location that other implementations will not
read.
Note that we are only defining the rules for format 1 here.
We do not ever write format 1 ourselves; it is a tool that
is meant to be used by users and future extensions to
provide safety with older implementations.

`missingTaggerEntry` in the receive.fsck.<msg-id> config setting.
Incidentally, the missing tagger warning is now really shown as a warning
(as opposed to being reported with the "error:" prefix, as it used to be
the case before this commit).

fsck: optionally ignore specific fsck issues completely
An fsck issue in a legacy repository might be so common that one would
like not to bother the user with mentioning it at all. With this change,
that is possible by setting the respective message type to "ignore".
This change "abuses" the missingEmail=warn test to verify that "ignore"
is also accepted and works correctly. And while at it, it makes sure
that multiple options work, too (they are passed to unpack-objects or
index-pack as a comma-separated list via the --strict=... command-line
option).
