NUL cannot appear in paths. Even disregarding filesystem path
limitations, the tree object format delimits with NUL, so such a path
cannot be encoded by Git.
When a quoted path is unquoted, it could possibly contain NUL from
"\000". Forbid it so it isn't truncated.
fast-import still has other issues with NUL, but those will be addressed
later.

The strbuf in `note_change_n` is to copy the remainder of `p` before
potentially invalidating it when reading the next line. However, `p` is
not used after that point. It has been unused since the function was
created in a8dd2e7d2b (fast-import: Add support for importing commit
notes, 2009-10-09) and looks to be a fossil from adapting
`file_change_m`. Remove it.

Ever since filerename was added in f39a946a1f (Support wholesale
directory renames in fast-import, 2007-07-09) and filecopy in b6f3481bb4
(Teach fast-import to recursively copy files/directories, 2007-07-15),
both have produced an error when the destination path is empty. Later,
when support for targeting the root directory with an empty string was
added in 2794ad5244 (fast-import: Allow filemodify to set the root,
2010-10-10), this had the effect of allowing the quoted empty string
(`""`), but forbidding its unquoted variant (``). This seems to have
been intended as simple data validation for parsing two paths, rather
than a syntax restriction, because it was not extended to the other
operations.
All other occurrences of paths (in filemodify, filedelete, the source of
filecopy and filerename, and ls) allow both.
For most of this feature's lifetime, the documentation has not
prescribed the use of quoted empty strings. In e5959106d6
(Documentation/fast-import: put explanation of M 040000 <dataref> "" in
context, 2011-01-15), its documentation was changed from “`<path>` may
also be an empty string (`""`) to specify the root of the tree” to “The
root of the tree can be represented by an empty string as `<path>`”.
Thus, we should assume that some front-ends have depended on this
behavior.
Remove this restriction for the destination paths of filecopy and
filerename and change tests targeting the root to test `""` and ``.

Previously, one case would not write the path to the strbuf: when the
path is unquoted and at the end of the string. It was essentially
copy-on-write. However, with the logic simplification of the previous
commit, this case was eliminated and the strbuf is always populated.
Directly use the strbufs now instead of an alias.
Since this already changes all the lines that use the strbufs, rename
them from `uq` to be more descriptive. That they are unquoted is not
their most important property, so name them after what they carry.
Additionally, `file_change_m` no longer needs to copy the path before
reading inline data.

Path parsing in fast-import is inconsistent and many unquoting errors
are suppressed or not checked.
<path> appears in the grammar in these places:
filemodify ::= 'M' SP <mode> (<dataref> | 'inline') SP <path> LF
filedelete ::= 'D' SP <path> LF
filecopy ::= 'C' SP <path> SP <path> LF
filerename ::= 'R' SP <path> SP <path> LF
ls ::= 'ls' SP <dataref> SP <path> LF
ls-commit ::= 'ls' SP <path> LF
and fast-import.c parses them in five different ways:
1. For filemodify and filedelete:
Try to unquote <path>. If it unquotes without errors, use the
unquoted version; otherwise, treat it as literal bytes to the end of
the line (including any number of SP).
2. For filecopy (source) and filerename (source):
Try to unquote <path>. If it unquotes without errors, use the
unquoted version; otherwise, treat it as literal bytes up to, but not
including, the next SP.
3. For filecopy (dest) and filerename (dest):
Like 1., but an unquoted empty string is forbidden.
4. For ls:
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes to the end of the line
(including any number of SP).
5. For ls-commit:
Unquote <path> and report parse errors.
(It must start with `"` to disambiguate from ls.)
In the first three, any errors from trying to unquote a string are
suppressed, so a quoted string that contains invalid escapes would be
interpreted as literal bytes. For example, `"\xff"` would fail to
unquote (because hex escapes are not supported), and it would instead be
interpreted as the byte sequence '"', '\\', 'x', 'f', 'f', '"', which is
certainly not intended. Some front-ends erroneously use their language's
standard quoting routine instead of matching Git's, which could silently
introduce escapes that would be incorrectly parsed due to this and lead
to data corruption.
The documentation states “To use a source path that contains SP the path
must be quoted.”, so it is expected that some implementations depend on
spaces being allowed in paths in the final position. Thus we have two
documented ways to parse paths, so simplify the implementation to that.
Now we have:
1. `parse_path_eol` for filemodify, filedelete, filecopy (dest),
filerename (dest), ls, and ls-commit:
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes to the end of the line
(including any number of SP).
2. `parse_path_space` for filecopy (source) and filerename (source):
If <path> starts with `"`, unquote it and report parse errors;
otherwise, treat it as literal bytes up to, but not including, the
next SP. It must be followed by SP.
There remain two special cases: The dest <path> in filecopy and rename
cannot be an unquoted empty string (this will be addressed subsequently)
and <path> in ls-commit must be quoted to disambiguate it from ls.

Some functions in Git's source code follow the convention that returning
a negative value indicates a fatal error, e.g. repository corruption.
Let's use this convention in `repo_in_merge_bases()` to report when one
of the specified commits is missing (i.e. when `repo_parse_commit()`
reports an error).
Also adjust the callers of `repo_in_merge_bases()` to handle such
negative return values.
Note: As of this patch, errors are returned only if any of the specified
merge heads is missing. Over the course of the next patches, missing
commits will also be reported by the `paint_down_to_common()` function,
which is called by `repo_in_merge_bases_many()`, and those errors will
be properly propagated back to the caller at that stage.

builtin/fast-import.c and tree-walk.c have almost identical version of
get_mode. The two functions started out the same but have diverged
slightly. The version in fast-import changed mode to a uint16_t to
save memory. The version in tree-walk started erroring if no mode was
present.
As far as I can tell both of these changes are valid for both of the
callers, so add the both changes and place the common parsing helper
in object.h
Rename the helper from get_mode to parse_mode so it does not
conflict with another helper named get_mode in diff-no-index.c
This will be used shortly in a new helper decode_tree_entry_raw

differences:
1. ->init_fn is required before all use
2. struct assignments don't work and requires ->clone_fn
3. can't support ->update_fn after ->final_*fn
While fixing cases 1 and 2 is merely the matter of calling ->init_fn and
->clone_fn as appropriate, fixing case 3 requires calling ->final_*fn on
a temporary context that's cloned from the primary context.

In cmd_fast_import(), we ignore the "prefix" argument entirely, even
though it tells us how we may have changed directory to the root of the
repository earlier in the process. Which means that if you run it from a
subdir and point to paths in the filesystem, like:
cd subdir
git fast-import --import-marks=foo <dump
then it will look for "foo" in the root of the repository, not the
current directory ("subdir/") which the user would have expected.
We can fix this by recording the prefix and using it as appropriate
whenever we open a file for reading or writing. I found each of these by
looking for cases where we call fopen() within fast-import.c, so this
should cover all cases. The new test triggers each one, as well as
making sure we don't accidentally apply the prefix when --relative-marks
is in use (since that option interprets some paths as relative to a
specific directory).

This commit introduces the infrastructure for the core.fsync
configuration knob. The repository components we want to sync
are identified by flags so that we can turn on or off syncing
for specific components.
If core.fsyncObjectFiles is set and the core.fsync configuration
also includes FSYNC_COMPONENT_LOOSE_OBJECT, we will fsync any
loose objects. This picks the strictest data integrity behavior
if core.fsync and core.fsyncObjectFiles are set to conflicting values.
This change introduces the currently unused fsync_component
helper, which will be used by a later patch that adds fsyncing to
the refs backend.
Actual configuration and documentation of the fsync components
list are in other patches in the series to separate review of
the underlying mechanism from the policy of how it's configured.

instead of "tree_type".
The "cat-file" caller is not on the codepath that

Add a convenience function to wrap the xsnprintf() command that
generates loose object headers. This code was copy/pasted in various
parts of the codebase, let's define it in one place and re-use it from
there.
All except one caller of it had a valid "enum object_type" for us,
it's only write_object_file_prepare() which might need to deal with
"git hash-object --literally" and a potential garbage type. Let's have
the primary API use an "enum object_type", and define a *_literally()
function that can take an arbitrary "const char *" for the type.
See [1] for the discussion that prompted this patch, i.e. new code in
object-file.c that wanted to copy/paste the xsnprintf() invocation.
In the case of fast-import.c the callers unfortunately need to cast
back & forth between "unsigned char *" and "char *", since
format_object_header() ad encode_in_pack_object_header() take
different signedness.

Change a few existing non-designated initializer assignments to use
"partial" designated initializer assignments. I.e. we're now omitting
the "NULL" or "0" fields and letting the initializer take care of them
for us.

Move the declaration of the date.c functions from cache.h, and adjust
the relevant users to include the new date.h header.
The show_ident_date() function belonged in pretty.h (it's defined in
pretty.c), its two users outside of pretty.c didn't strictly need to
include pretty.h, as they get it indirectly, but let's add it to them
anyway.
Similarly, the change to "builtin/{fast-import,show-branch,tag}.c"
isn't needed as far as the compiler is concerned, but since they all
use the "DATE_MODE()" macro we now define in date.h, let's have them
include it.
We could simply include this new header in "cache.h", but as this
change shows these functions weren't common enough to warrant
including in it in the first place. By moving them out of cache.h
changes to this API will no longer cause a (mostly) full re-build of
the project when "make" is run.

Change code that printed its own "fatal: " message and exited with a
status code of 128 to use the die_message() function added in a
preceding commit.
This change also demonstrates why the return value of
die_message_routine() needed to be that of "report_fn". We have
callers such as the run-command.c::child_err_spew() which would like
to replace its error routine with the return value of
"get_die_message_routine()".

When we're hashing a value which is going to be an object ID, we want to
zero-pad that value if necessary. To do so, use the final_oid_fn
instead of the final_fn anytime we're going to create an object ID to
ensure we perform this operation.

In the future, we'll want oidread to automatically set the hash
algorithm member for an object ID we read into it, so ensure we use
oidread instead of hashcpy everywhere we're copying a hash value into a
struct object_id.

Add and apply a semantic patch for converting code that open-codes
CALLOC_ARRAY to use it instead. It shortens the code and infers the
element size automatically.

Commit 1bdca81641 (fast-import: add options for rewriting submodules,
2020-02-22) accidentally added two lines parsing the option
"rewrite-submodules-from". This didn't do anything in practice, because
they're in an if/else chain and so the second one can never trigger.
