merge: cleanup messages like commit
This change allows git-merge messages to be cleaned up with the
commit.cleanup configuration or --cleanup option, just like how
git-commit does it.
We also give git-pull the option of --cleanup so that it can also take
advantage of this change.
Finally, add testing to ensure that messages are properly cleaned up.
Note that some newlines that were added to the commit message were
removed so that if a file were read via -F, it would be copied
faithfully.

clone: send server options when using protocol v2
Commit
5e3548ef16 ("fetch: send server options when using protocol v2",
2018-04-24) taught "fetch" the ability to send server options when using
protocol v2, but not "clone". This ability is triggered by "-o" or
"--server-option".
Teach "clone" the same ability, except that because "clone" already
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
receive-pack's handling of push options - currently, they are just sent
to hooks to interpret as they see fit.

ref-filter: use correct branch for %(push:track)
In ref-filter.c, when processing the atom %(push:track), the
ahead/behind values are computed using `stat_tracking_info` which refers
to the upstream branch.
Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
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
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.
This changes the expected value of some following tests (by introducing
new references), so update them too.

submodules (I've seen one with 67) this is really annoying.
The warning was there because we could not resolve extended SHA-1

commit.cocci: refactor code, avoid double rewrite
"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.

packfile: fix pack basename computation
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

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.

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.

pkt-line: prepare buffer before handling ERR packets
Since

automatically, saving the caller from dealing with it. But we do so too

As a result, passing the ERR message to die() may result in us printing
random cruft from a previous packet. This doesn't trigger memory tools
like ASan because we reuse the same buffer over and over (so the
contents are valid and initialized; they're just stale).
We can see demonstrate this by tightening the regex we use to match the
error message in t5516; without this patch, git-fetch will accidentally
print the capabilities from the (much longer) initial packet we

By moving the ERR code later in the function we get a few other

upload-pack: send ERR packet for non-tip objects
Commit
bdb31eada7 (upload-pack: report "not our ref" to client,
2017-02-23) catches the case where a client asks for an object we don't
have, and issues a message that the client can show to the user (in
addition to dying and writing to stderr).
There's a similar case (with the same message) when the client asks for
an object which we _do_ have, but which isn't a ref tip (or isn't
reachable, when uploadpack.allowReachableSHA1InWant is true). Let's give
that one the same treatment, for the same reason (namely that it's more
informative to the client than just hanging up, since they won't see our
stderr over some protocols).
There are two tests here. We cover it most directly in t5530 by invoking
upload-pack, which matches the existing "not our ref" test.
But a more end-to-end check is that "git fetch" actually shows the
message to the client. We're already checking in t5516 that this case
fails, so we can just check stderr there, too. Note that even after we
started ignoring SIGPIPE in
8bf4becf0c, this could in theory still be
racy as described in that commit (because we die() on write failures
before pumping the connection for any ERR packets).
In practice this should be OK for this case. The server will not
actually check reachability until it has received our whole group of
"want" lines. And since we have no objects in the repository, we won't
send any "have" lines, meaning we're always waiting to read the server
response.
Note also that this case cannot happen in the v2 protocol, since it
allows any available object to be requested. However, we don't have to
take any steps to protect against the upcoming GIT_TEST_PROTOCOL_VERSION
in our tests:
- the tests in t5516 would already need to be skipped under v2, and
that is covered by
ab0c5f5096 (tests: always test fetch of
unreachable with v0, 2019-02-25)
- the tests in t5530 invoke upload-pack directly, which will continue
to default to v0. Eventually we may have a test setting which uses
v2 even for bare upload-pack calls, but we can't override it here

progress: clear previous progress update dynamically
When the progress bar includes throughput, its length can shorten as
the unit of display changes from KiB to MiB. To cover up remnants of
the previous progress bar when such a change of units happens we
always print three spaces at the end of the progress bar.
Alas, covering only three characters is not quite enough: when both
the total and the throughput happen to change units from KiB to MiB in
the same update, then the progress bar's length is shortened by four
characters (or maybe even more!):
Receiving objects: 25% (2901/11603), 772.01 KiB | 733.00 KiB/s
Receiving objects: 27% (3133/11603), 1.43 MiB | 1.16 MiB/s s
and a stray 's' is left behind.
So instead of hard-coding the three characters to cover, let's compare
the length of the current progress bar with the previous one, and
cover up as many characters as needed.
Sure, it would be much simpler to just print more spaces at the end of
the progress bar, but this approach is more future-proof, and it won't
print extra spaces when none are needed, notably when the progress bar
doesn't show throughput and thus never shrinks.

Note: for some reason, this is a change of behavior caused by the

submodule foreach: fix "<command> --quiet" not being respected
Robin reported that
git submodule foreach --quiet git pull --quiet origin
is not really quiet anymore [1]. "git pull" behaves as if --quiet is not
given.
This happens because parseopt in submodule--helper will try to parse
both --quiet options as if they are foreach's options, not git-pull's.
The parsed options are removed from the command line. So when we do
pull later, we execute just this
git pull origin
When calling submodule helper, adding "--" in front of "git pull" will
stop parseopt for parsing options that do not really belong to
submodule--helper foreach.
PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should
never see unknown options or something has gone wrong. There are also
a couple usage string update while I'm looking at them.
While at it, I also add "--" to other subcommands that pass "$@" to
submodule--helper. "$@" in these cases are paths and less likely to be
--something-like-this. But the point still stands, git-submodule has
parsed and classified what are options, what are paths. submodule--helper
should never consider paths passed by git-submodule to be options even
if they look like one.
The test case is also contributed by Robin.
[1] it should be quiet before
fc1b9243cd (submodule: port submodule
subcommand 'foreach' from shell to C, 2018-05-10) because parseopt
can't accidentally eat options then.

tests: disallow the use of abbreviated options (by default)
Git's command-line parsers support uniquely abbreviated options, e.g.
`git init --ba` would automatically expand `--ba` to `--bare`.
This is a very convenient feature in every day life for Git users, in
particular when tab completion is not available.
However, it is not a good idea to rely on that in Git's test suite, as
something that is a unique abbreviation of a command line option today
might no longer be a unique abbreviation tomorrow.
For example, if a future contribution added a new mode
`git init --babyproofing` and a previously-introduced test case used the
fact that `git init --ba` expanded to `git init --bare`, that future
contribution would now have to touch seemingly unrelated tests just to
keep the test suite from failing.
So let's disallow abbreviated options in the test suite by default.
Note: for ease of implementation, this patch really only touches the
`parse-options` machinery: more and more hand-rolled option parsers are
converted to use that internal API, and more and more scripts are
converted to built-ins (naturally using the parse-options API, too), so
in practice this catches most issues, and is definitely the biggest bang
for the buck.

replace: peel tag when passing a tag first to --graft
When passing a tag as the first argument to `git replace --graft`,

for annotated tags we have been using the hash of the tag object

send-email: default to quoted-printable when CR is present
In
7a36987fff ("send-email: add an auto option for transfer encoding",
2018-07-08), git send-email learned how to automatically determine the
transfer encoding for a patch. However, the only criterion considered
was the length of the lines.
Another case we need to consider is that of carriage returns. Because
emails have CRLF endings when canonicalized, we don't want to write raw
carriage returns into a patch, lest they be stripped off as an artifact
of the transport. Ensure that we choose quoted-printable encoding if the
patch we're sending contains carriage returns.
Note that we are guaranteed to always correctly encode carriage returns
when writing quoted-printable since we explicitly specify the line
ending as "\n", forcing MIME::QuotedPrint to encode our carriage return
as "=0D".

progress: use xmalloc/xcalloc
Since the early days of Git, the progress code allocates its struct with
a bare malloc(), not xmalloc(). If the allocation fails, we just avoid
showing progress at all.
While perhaps a noble goal not to fail the whole operation because of
optional progress, in practice:
1. Any failure to allocate a few dozen bytes here means critical path
allocations are likely to fail, too.
2. These days we use a strbuf for throughput progress (and there's a
patch under discussion to do the same for non-throughput cases,
too). And that uses xmalloc() under the hood, which means we'd
still die on some allocation failures.
Let's switch to xmalloc(). That makes us consistent with the rest of Git
and makes it easier to audit for other (less careful) bare mallocs.

xdiff: use xmalloc/xrealloc
Most of xdiff uses a bare malloc() to allocate memory, and returns an
error when we get NULL. However, there are a few spots which don't check
the return value and may segfault, including at least xdl_merge() and
xpatience.c's find_longest_common_sequence().
Let's use xmalloc() everywhere instead, so that we get a graceful die()
for these cases, without having to do further auditing. This does mean
the existing cases which check errors will now die() instead of
returning an error up the stack. But:
- that's how the rest of Git behaves already for malloc errors
- all of the callers of xdi_diff(), etc, die upon seeing an error
So while we might one day want to fully lib-ify the diff code and make
it possible to use as part of a long-running process, we're not close to
that now. And because we're just tweaking the xdl_malloc() macro here,
we're not really moving ourselves any further away from that. We
could, for example, simplify some of the functions which handle malloc()
errors which can no longer occur. But that would probably be taking us
in the wrong direction.
This also makes our malloc handling more consistent with the rest of
Git, including enforcing GIT_ALLOC_LIMIT and trying to reclaim pack
memory when needed.
