Commit e8adf23 (xdl_change_compact(): introduce the concept
of a change group, 2016-08-22) added a "struct group" type
to xdiff/xdiffi.c. But the POSIX system header "grp.h"
already defines "struct group" (it is part of the getgrnam
interface). This happens to work because the new type is
local to xdiffi.c, and the xdiff code includes a relatively
small set of system headers. But it will break compilation
if xdiff ever switches to using git-compat-util.h. It can
also probably cause confusion with tools that look at the
whole code base, like coccinelle or ctags.
Let's resolve by giving the xdiff variant a scoped name,
which is closer to other xdiff types anyway (e.g.,
xdlfile_t, though note that xdiff is fond if typedefs when
Git usually is not).

contrib/coccinelle: fix semantic patch for oid_to_hex_r()
When the user gives us an ambiguous short sha1, we print an
error and refuse to resolve it. In some cases, the next step
is for them to feed us more characters (e.g., if they were
retyping or cut-and-pasting from a full sha1). But in other
cases, that might be all they have. For example, an old
commit message may have used a 7-character hex that was
unique at the time, but is now ambiguous. Git doesn't
provide any information about the ambiguous objects it
found, so it's hard for the user to find out which one they
probably meant.
This patch teaches get_short_sha1() to list the sha1s of the
objects it found, along with a few bits of information that
may help the user decide which one they meant. Here's what
it looks like on git.git:
$ git rev-parse b2e1
error: short SHA1 b2e1 is ambiguous
hint: The candidates are:
hint: b2e1196 tag v2.8.0-rc1
hint: b2e11d1 tree
hint: b2e1632 commit 2007-11-14 - Merge branch 'bs/maint-commit-options'
hint: b2e1759 blob
hint: b2e18954 blob
hint: b2e1895c blob
fatal: ambiguous argument 'b2e1': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
We show the tagname for tags, and the date and subject for
commits. For trees and blobs, in theory we could dig in the
history to find the paths at which they were present. But
that's very expensive (on the order of 30s for the kernel),
and it's not likely to be all that helpful. Most short
references are to commits, so the useful information is
typically going to be that the object in question _isn't_ a
commit. So it's silly to spend a lot of CPU preemptively
digging up the path; the user can do it themselves if they
really need to.
And of course it's somewhat ironic that we abbreviate the
sha1s in the disambiguation hint. But full sha1s would cause
annoying line wrapping for the commit lines, and presumably
the user is going to just re-issue their command immediately
with the corrected sha1.
We also restrict the list to those that match any
disambiguation hint. E.g.:
$ git rev-parse b2e1:foo
error: short SHA1 b2e1 is ambiguous
hint: The candidates are:
hint: b2e1196 tag v2.8.0-rc1
hint: b2e11d1 tree
hint: b2e1632 commit 2007-11-14 - Merge branch 'bs/maint-commit-options'
fatal: Invalid object name 'b2e1'.
does not bother reporting the blobs, because they cannot
work as a treeish.

If an object appears multiple times in the object database
(e.g., in both loose and packed form, or in two separate
packs), the disambiguation machinery may see it more than
once. The get_short_sha1() function handles this already,
but for_each_abbrev() blindly fires the callback for each
instance it finds.
We can fix this by collecting the output in a sha1 array and
de-duplicating it. As a bonus, the sort done for the
de-duplication means that our output will be stable,
regardless of the order in which the objects are found.
Note that the old code normalized the callback's output to
0/1 to store in the 1-bit ds->ambiguous flag (which both
halted the iteration and was returned from the
for_each_abbrev function). Now that we are using sha1_array,
we can return the real value. In practice, it doesn't matter
as the sole caller only ever returns 0.

We store the hex prefix in a 40-byte buffer with the prefix
itself followed by 40-minus-len "x" characters. These x's
serve no purpose, and the lack of NUL termination makes the
prefix string annoying to use. Let's just terminate it.
Note that this is in contrast to the binary prefix, which
_must_ be zero-padded, because we look at the whole thing
during a binary search to find the first potential match in
each pack index. The loose-object hex search cannot use the
same trick because it has to do a linear walk through the
unsorted results of readdir() (and even if it could, you'd
want zeroes instead of x's).

The disambiguation machinery has two callers: get_short_sha1
and for_each_abbrev. Both need to repeat much of the same
setup: declaring buffers, sanity-checking lengths, preparing
the prefixes, etc. Let's pull that into a single init
function so we can avoid repeating ourselves.
Pulling the buffers into the "struct disambiguate_state"
isn't strictly necessary, but it does make things simpler
for the callers, who no longer have to worry about sizing
them correctly (i.e., it's an implicit requirement that
the caller provide 20- and 40-byte buffers).
And while we're touching this code, we can convert any
magic-number sizes to the more modern GIT_SHA1_* constants.

The treeish disambiguation function tries to peel tags, but
it does so by calling:
deref_tag(lookup_object(sha1), ...);
This will only work if we have previously looked at the tag
and created a "struct tag" for it. Since parsing revision
arguments typically happens before anything else, this is
usually not the case, and we would fail to peel the tag (we
are lucky that deref_tag() gracefully handles the NULL and
does not segfault).
Instead, we can use parse_object(). Note that this is the
same fix done by 94d75d1 (get_short_sha1(): correctly
disambiguate type-limited abbreviation, 2013-07-01), but
that commit fixed only the committish disambiguator, and
left the bug in the treeish one.

The get_sha1() function is actually implementation by many
sub-functions, but we do not always pass our flags around to
all of those functions. As a result, we may forget that our
caller asked us to resolve with GET_SHA1_QUIETLY and output
messages. The two triggerable cases are:
1. Resolving treeish:path will resolve the "treeish"
portion using GET_SHA1_TREEISH, dropping all other
flags.
2. The peel_onion() function did not take flags at all
but recurses to get_sha1_1(), which does.
The solution for both is to bitwise-OR their new flags with
the existing ones (after dropping any mutually exclusive
disambiguation flags).
This bug can trigger with "git rev-parse --quiet", which
asks for quiet resolution. But it can also happen in a more
vanilla code path when we do a follow-up ONLY_TO_DIE
invocation of get_sha1(), and that's what the tests check.

When the revision code cannot parse an argument like
"HEAD:foo", it will call maybe_die_on_misspelt_object_name(),
which re-runs get_sha1() with an extra ONLY_TO_DIE flag. We
then spend more effort to generate a better error message.
Unfortunately, a side effect is that our second call may
repeat the same error messages from the original get_sha1()
call. You can see this with:
$ git show 0017
error: short SHA1 0017 is ambiguous.
error: short SHA1 0017 is ambiguous.
fatal: ambiguous argument '0017': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
where the second "error:" line comes from the ONLY_TO_DIE
call.
To fix this, we can make ONLY_TO_DIE imply QUIETLY. This is
a little odd, because the whole point of ONLY_TO_DIE is to
output error messages. But what we want to do is tell the
rest of the get_sha1() code (particularly get_sha1_1()) that
the _regular_ messages should be quiet, but the only-to-die
ones should not.

The get_sha1() family of functions takes a flags field, but
some of the flags are mutually exclusive. In particular, we
can only handle one disambiguating function, and the flags
quietly override each other. Let's instead detect these as
programming bugs.
Technically some of the flags are supersets of the others,
so treating COMMITTISH|TREEISH as just COMMITTISH is not
wrong, but it's a good sign the caller is confused. And
certainly asking for BLOB|TREE does not work.
We can do the check easily with some bit-twiddling, and as a
bonus, the bit-mask of disambiguators will come in handy in
a future patch.

When opening a loose object file, we often do this sequence:
- prepare a short buffer for the object header (on stack)
- call unpack_sha1_header() and have early part of the object data
inflated, enough to fill the buffer
- parse that data in the short buffer, assuming that the first part
of the object is <typename> SP <length> NUL
Because the parsing function parse_sha1_header_extended() is not
given the number of bytes inflated into the header buffer, it you
craft a file whose early part inflates a garbage sequence without SP
or NUL, and replace a loose object with it, it will end up reading
past the end of the inflated data.
To correct this, do the following four things:
- rename unpack_sha1_header() to unpack_sha1_short_header() and
have unpack_sha1_header_to_strbuf() keep calling that as its
helper function. This will detect and report zlib errors, but is
not aware of the format of a loose object (as before).
- introduce unpack_sha1_header() that calls the same helper
function, and when zlib reports it inflated OK into the buffer,
check if the inflated data has NUL. This would ensure that
parsing function will terminate within the buffer that holds the
inflated header.
- update unpack_sha1_header_to_strbuf() to check if the resulting
buffer has NUL for the same effect.
- update parse_sha1_header_extended() to make sure that its loop to
find the SP that terminates the <typename> stops at NUL.
Essentially, this makes unpack_*() functions that are asked to
unpack a loose object header to be a bit more strict and detect an
input that cannot possibly be a valid object header, even before the
parsing function kicks in.

Add COPY_ARRAY, a safe and convenient helper for copying arrays,
complementing ALLOC_ARRAY and REALLOC_ARRAY. Users just specify source,
destination and the number of elements; the size of an element is
inferred automatically.
It checks if the multiplication of size and element count overflows.
The inferred size is passed first to st_mult, which allows the division
there to be done at compilation time.
As a basic type safety check it makes sure the sizes of source and
destination elements are the same. That's evaluated at compilation time
as well.
COPY_ARRAY is safe to use with NULL as source pointer iff 0 elements are
to be copied. That convention is used in some cases for initializing
arrays. Raw memcpy(3) does not support it -- compilers are allowed to
assume that only valid pointers are passed to it and can optimize away
NULL checks after such a call.

The "highlight" binary can, in some cases, determine the language type

which syntax is not known by gitweb. In that case, pass the blob
contents to "highlight --force"; the parameter is needed to make it
always generate HTML output (which includes HTML-escaping).
Although we now run highlight on files which do not end up highlighted,
performance is virtually unaffected because when we call highlight, it
is used for escaping HTML. In the case that highlight is used, gitweb
calls sanitize() instead of esc_html(), and the latter is significantly
slower (it does more, being roughly a superset of sanitize()). Simple
benchmark comparing performance of 'blob' view of files without syntax
highlighting in gitweb before and after this change indicates ±1%
difference in request time for all file types. Benchmark was performed
on local instance on Debian, using Apache/2.4.23 web server and CGI.

The function needs_work_tree_config() that is called from

In the current code, however, we feed the return value from
get_git_dir(), which can be totally different from what the function
expects when "gitdir" file is involved. Instead of giving the path to

indirectly calls get_common_dir() and correctly detects multiple

return correct paths in both single and multiple worktree setups. The

negotiation if a number of consecutive "have"s have been sent with no
corresponding new acks. This is to stop the client from digging too deep
in an irrelevant side branch in vain without ever finding a common
ancestor. A use case (as described in that commit) is the scenario in
which the local repository has more roots than the remote repository.
However, during a negotiation in which stateless RPCs are used,
MAX_IN_VAIN will (almost) never trigger (in the more-roots scenario
above and others) because in each new request, the client has to inform
the server of objects it already has and knows the server has (to remind
the server of the state), which the server then acks.
Make fetch-pack only consider, as new acks for the purpose of
MAX_IN_VAIN, acks for objects for which the client has never received an
ack before in this session.

If there isn't a canonical name, getaddrinfo() will
generally return either a NULL addrinfo list, or one in

However, if the result of gethostname() looks like an IP

up with an ident, but also where the hostname is a number
with no dots. But I was able to replicate the bug by faking
