test-tool: handle the `-C <directory>` option just like `git`
In preparation for moving `git serve` into `test-tool` (because it
really is only used by the test suite), we teach the `test-tool` the
useful trick to change the working directory before running the test
command, which will avoid introducing subshells in the test code.

check-docs: do not bother checking for legacy scripts' documentation
In the recent years, there has been a big push to convert more and more
of Git's commands that are implemented as scripts to built-ins written
in pure, portable C, for robustness, speed and portability.
One strategy that served us well is to convert those scripts
incrementally, starting by renaming the scripts to
`git-legacy-<command>`, then introducing a built-in that does nothing
else at first than checking the config setting `<command>.useBuiltin`
(which defaults to `false` at the outset) and handing off to the legacy
script if so asked.
Obviously, those `git-legacy-<command>` commands share the documentation
with the built-in `git-<command>`, and are not intended to be called
directly anyway. So let's not try to ensure that they are documented
separately from their built-in versions.

docs: exclude documentation for commands that have been excluded
When building with certain build options, some commands are excluded
from the build. For example, `git-credential-cache` is skipped when
building with `NO_UNIX_SOCKETS`.
Let's not build or package documentation for those excluded commands.
This issue was pointed out rightfully when running `make check-docs` on
Windows, where we do not yet have Unix sockets, and therefore the
`credential-cache` command is excluded (yet its documentation was built
and shipped).
Note: building the documentation via `make -C Documentation` leaves the
build system with no way to determine which commands have been
excluded. If called thusly, we gracefully fail to exclude their
documentation. Only when building the documentation via the top-level
Makefile will it get excluded properly, or after building
`Documentation/GIT-EXCLUDED-PROGRAMS` manually.

However, some build options exclude commands from the latter. Fix the
target to handle this situation correctly by taking the just-introduced
`$(EXCLUDED_PROGRAMS)` into account.

has "-o" for another parameter, teach "clone" only to receive
"--server-option".
Explain in the documentation, both for clone and for fetch, that server
handling of server options are server-specific. This is similar to

Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.
This bug was not detected in t/t6300-for-each-ref.sh because in the test

behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.

right repository to use.
the_repository would be correct most of the time. But we're relying less

"maybe" pointer in 'struct commit' is tricky because it can be lazily
initialized to take advantage of commit-graph if available. This makes
it not safe to access directly.
This leads to a rule in commit.cocci to rewrite 'x->maybe_tree' to
'get_commit_tree(x)'. But that rule alone could lead to incorrectly
rewrite assignments, e.g. from
x->maybe_tree = yes
to
get_commit_tree(x) = yes
Because of this we have a second rule to revert this effect. Szeder
found out that we could do better by performing the assignment rewrite
rule first, then the remaining is read-only access and handled by the
current first rule.
For this to work, we need to transform "x->maybe_tree = y" to something
that does NOT contain "x->maybe_tree" to avoid the original first
rule. This is where set_commit_tree() comes in.

When writing objects/info/packs, we use the basename of each pack
(i.e., just the "pack-1234abcd.pack" part). We compute that manually by
adding "objdirlen + 6" to the name.
This _should_ work consistently, as we do not include non-local packs,
meaning everything should be in $objdir/pack/. Before f13d7db4af
(server-info.c: use pack_local like everybody else., 2005-12-05), this
was definitely true, since we computed "local" based on comparing the
objdir string. Since then, we're relying on the code on packfile.c to
match our expectations of p->pack_name and p->local.
I think our expectations do still hold today, but we can be a bit more
defensive by just using pack_basename() to get the base. That
future-proofs us, and should hopefully be more obviously safe to
somebody reading the code.

We keep an array of struct pointers, with each one representing a single
packfile. But for some reason there is a nr_alloc parameter inside each
struct, which has never been used.
This is probably cruft left over from development, where we might have
wanted a nr_alloc to dynamically grow the list. But as it turns out, we
do not dynamically grow the list at all, but rather count up the total
number of packs and use that as a maximum size. So while we're thinking
of this, let's add an assert() that documents (and checks!) that our
allocation and fill loops stay in sync.

When we're writing out a new objects/info/packs file, we read back the
old one to try to keep the ordering the same. When we see a line
starting with "P", we expect "P pack-1234..." and blindly jump to "line
+ 2" to parse the pack name. If we saw a line with _just_ "P" and
nothing else, we'd jump past the end of the buffer and start reading
arbitrary memory.
This shouldn't be a big attack vector, as the files are local to the
repository and written by us, but it's clearly worth fixing (we do read
remote copies of the file for dumb-http fetches, but using a totally
different parser!).
Let's instead use skip_prefix() here, which avoids pointer arithmetic
altogether. Note that this converts our switch statement to an if/else
chain, making it slightly more verbose. But it will also make it easier

http: simplify parsing of remote objects/info/packs
We can use skip_prefix() and parse_oid_hex() to continuously increment
our pointer, rather than dealing with magic numbers. This also fixes a
few small shortcomings:
- if we see a line with the right prefix, suffix, and length, i.e.
matching /P pack-.{40}.pack\n/, we'll interpret the middle part as
hex without checking if it could be parsed. This could lead to us
looking at uninitialized garbage in the hash array. In practice this
means we'll just make a garbage request to the server which will
fail, though it's interesting that a malicious server could convince
us to leak 40 bytes of uninitialized stack to them.
- the current code is picky about seeing a newline at the end of file,
but we can easily be more liberal

When we have a multi-pack-index that covers many packfiles, we try to
avoid opening the .idx for those packfiles. To do that we feed the pack
name to midx_contains_pack(). But that function wants to see only the
basename, which we compute using strrchr() to find the final slash. But
that leaves an extra "/" at the start of our string.
We can fix this by incrementing the pointer. That also raises the
question of what to do when the name does not have a '/' at all. This
should generally not happen (we always find files in "pack/"), but it
doesn't hurt to be defensive here.
Let's wrap all of that up in a helper function and make it publicly
available, since a later patch will need to use it, too.
The tests don't notice because there's nothing about opening those .idx
files that would cause us to give incorrect output. It's just a little
slower. The new test checks this case by corrupting the covered .idx,
and then making sure we don't complain about it.
We also have to tweak t5570, which intentionally corrupts a .idx file
and expects us to notice it. When run with GIT_TEST_MULTI_PACK_INDEX,
this will fail since we now will (correctly) not bother opening the .idx
at all. We can fix that by unconditionally dropping any midx that's
there, which ensures we'll have to read the .idx.

midx: check both pack and index names for containment
A midx file (and the struct we parse from it) contains a list of all of
the covered packfiles, mentioned by their ".idx" names (e.g.,
"pack-1234.idx", etc). And thus calls to midx_contains_pack() expect
callers to provide the idx name.
This works for most of the calls, but the one in open_packed_git_1()
tries to feed a packed_git->pack_name, which is the ".pack" name,
meaning we'll never find a match (even if the pack is covered by the
midx).
We can fix this by converting the ".pack" to ".idx" in the caller.
However, that requires allocating a new string. Instead, let's make
midx_contains_pack() a bit friendlier, and allow it take _either_ the
.pack or .idx variant.
All cleverness in the matching code is credited to René. Bugs are mine.
There's no test here, because while this does fix _a_ bug, it's masked
by another bug in that same caller. That will be covered (with a test)
in the next patch.

We can't create a pack revindex if we haven't actually looked at the
index. Normally we would never get as far as creating a revindex without
having already been looking in the pack, so this code never bothered to
double-check that pack->index_data had been loaded.
But with the new multi-pack-index feature, many code paths might not
load the individual pack .idx at all (they'd find objects via the midx
and then open the .pack, but not its index).
This can't yet be triggered in practice, because a bug in the midx code
means we accidentally open up the individual .idx files anyway. But in
preparation for fixing that, let's have the revindex code check that
everything it needs has been loaded.
In most cases this will just be a quick noop. But note that this does
introduce a possibility of error (if we have to open the index and it's
corrupt), so load_pack_revindex() now returns a result code, and callers
need to handle the error.

trace2: use system/global config for default trace2 settings

Only the system and global config files are used. Repo and worktree
local config files are ignored. Likewise, the "-c" command line
arguments are also ignored. These limits are for performance reasons.
(1) For users not using Trace2, there should be minimal overhead to
detect that Trace2 is not enabled. In particular, Trace2 should not
allocate lots of otherwise unused data strucutres.

fetch: do not consider peeled tags as advertised tips
Our filter_refs() function accidentally considers the target of a peeled
tag to be advertised by the server, even though upload-pack on the
server side does not consider it so. This can result in the client
making a bogus fetch to the server, which will end with the server
complaining "not our ref". Whereas the correct behavior is for the
client to notice that the server will not allow the request and error
out immediately.
So as bugs go, this is not very serious (the outcome is the same either
way -- the fetch fails). But it's worth making the logic here correct
and consistent with other related cases (e.g., fetching an oid that the
server did not mention at all).
The crux of the issue comes from fdb69d33c4 (fetch-pack: always allow
fetching of literal SHA1s, 2017-05-15). After that, the strategy of
filter_refs() is basically:
- for each advertised ref, try to match it with a "sought" ref
provided by the user. Skip any malformed refs (which includes
peeled values like "refs/tags/foo^{}"), and place any unmatched
items onto the unmatched list.
- if there are unmatched sought refs, then put all of the advertised
tips into an oidset, including the unmatched ones.
- for each sought ref, see if it's in the oidset, in which case it's
legal for us to ask the server for it
The problem is in the second step. Our list of unmatched refs includes
the peeled refs, even though upload-pack does not allow them to be
directly fetched. So the simplest fix would be to exclude them during
that step.
However, we can observe that the unmatched list isn't used for anything
else, and is freed at the end. We can just free those malformed refs
immediately. That saves us having to check each ref a second time to see
if it's malformed.
Note that this code only kicks in when "strict" is in effect. I.e., if
we are using the v0 protocol and uploadpack.allowReachableSHA1InWant is
not in effect. With v2, all oids are allowed, and we do not bother
creating or consulting the oidset at all. To future-proof our test
against the upcoming GIT_TEST_PROTOCOL_VERSION flag, we'll manually mark
it as a v0-only test.

We provide a free_refs() function to free a list, but there's no easy
way for a caller to free a single ref. Let's make our singular
free_ref() function public. Since its name is so similar to the
list-freeing free_refs(), and because both of those functions have the
same signature, it might be easy to accidentally use the wrong one.
Let's call the singular version the more verbose "free_one_ref()" to
distinguish it.
