The main hunk loop for add--interactive will loop if it does
not get a known input. This is a good thing if the user
typed some invalid input. However, if we have an
uncorrectable read error, we'll end up looping infinitely.
We can fix this by noticing read errors (i.e., <STDIN>
returns undef) and breaking out of the loop.
One easy way to trigger this is if you have an editor that
does not take over the terminal (e.g., one that spawns a
window in an existing process and waits), start the editor
with the hunk-edit command, and hit ^C to send SIGINT. The
editor process dies due to SIGINT, but the perl
add--interactive process does not (perl suspends SIGINT for
the duration of our system() call).
We return to the main loop, but further reads from stdin
don't work. The SIGINT _also_ killed our parent git process,
which orphans our process group, meaning that further reads
from the terminal will always fail. We loop infinitely,
getting EIO on each read.
Note that there are several other spots where we read from
stdin, too. However, in each of those cases, we do something
sane when the read returns undef (breaking out of the loop,
taking the input as "no", etc). They don't need similar
treatment.

To figure out the author ident for a commit, we call
determine_author_info(). This function collects information
from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then
uses fmt_ident to generate the final ident string that goes
into the commit object. fmt_ident is therefore responsible
for any quality or validation checks on what is allowed to
go into a commit.
Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field). If this parsing or validation fails, we skip
updating the environment variables.
This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).
If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.
Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.
When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational. Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.
We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).
In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.
We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

When git is compiled with "-fsanitize=address" (using clang
or gcc >= 4.8), all invocations of git will check for buffer
overflows. This is similar to running with valgrind, except
that it is more thorough (because of the compiler support,
function-local buffers can be checked, too) and runs much
faster (making it much less painful to run the whole test
suite with the checks turned on).
Unlike valgrind, the magic happens at compile-time, so we
don't need the same infrastructure in the test suite that we
did to support --valgrind. But there are two things we can
help with:
1. On some platforms, the leak-detector is on by default,
and causes every invocation of "git init" (and thus
every test script) to fail. Since running git with
the leak detector is pointless, let's shut it off
automatically in the tests, unless the user has already
configured it.
2. When apache runs a CGI, it clears the environment of
unknown variables. This means that the $ASAN_OPTIONS
config doesn't make it to git-http-backend, and it
dies due to the leak detector. Let's mark the variable
as OK for apache to pass.
With these two changes, running
make CC=clang CFLAGS=-fsanitize=address test
works out of the box.

If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.
Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.
So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

When we send out pkt-lines with refnames, we use a static
1000-byte buffer. This means that the maximum size of a ref
over the git protocol is around 950 bytes (the exact size
depends on the protocol line being written, but figure on a sha1
plus some boilerplate).
This is enough for any sane workflow, but occasionally odd
things happen (e.g., a bug may create a ref "foo/foo/foo/..."
accidentally). With the current code, you cannot even use
"push" to delete such a ref from a remote.
Let's switch to using a strbuf, with a hard-limit of
LARGE_PACKET_MAX (which is specified by the protocol). This
matches the size of the readers, as of 74543a0 (pkt-line:
provide a LARGE_PACKET_MAX static buffer, 2013-02-20).
Versions of git older than that will complain about our
large packets, but it's really no worse than the current
behavior. Right now the sender barfs with "impossibly long
line" trying to send the packet, and afterwards the reader
will barf with "protocol error: bad line length %d", which
is arguably better anyway.
Note that we're not really _solving_ the problem here, but
just bumping the limits. In theory, the length of a ref is
unbounded, and pkt-line can only represent sizes up to
65531 bytes. So we are just bumping the limit, not removing
it. But hopefully 64K should be enough for anyone.
As a bonus, by using a strbuf for the formatting we can
eliminate an unnecessary copy in format_buf_write.

Current code uses a fixed PATH_MAX-sized buffer for reading
packed-refs lines. This is a reasonable guess, in the sense
that git generally cannot work with refs larger than
PATH_MAX. However, there are a few cases where it is not
great:
1. Some systems may have a low value of PATH_MAX, but can
actually handle larger paths in practice. Fixing this
code path probably isn't enough to make them work
completely with long refs, but it is a step in the
right direction.
2. We use fgets, which will happily give us half a line on
the first read, and then the rest of the line on the
second. This is probably OK in practice, because our
refline parser is careful enough to look for the
trailing newline on the first line. The second line may
look like a peeled line to us, but since "^" is illegal
in refnames, it is not likely to come up.
Still, it does not hurt to be more careful.

Be explicit that the --assume-unchanged contract is by the user that

Mentioning "Git stops checking" does not help the reader, as it is
only one possible consequence of what that assumption allows Git to
do, but
(1) there are things other than "stop checking" that Git can do
based on that assumption; and
(2) Git is not obliged to stop checking; it merely is allowed to.

The old compiler is wrong, of course, as the switch (method & 3)

When we detect an invalid tag-name header in a tag object,
like, "tag foo bar\n", we feed the pointer starting at "foo
bar" to a printf "%s" formatter. This shows the name, as we
want, but then it keeps printing the rest of the tag buffer,
rather than stopping at the end of the line.
Our tests did not notice because they look only for the
matching line, but the bug is that we print much more than
we wanted to. So we also adjust the test to be more exact.
Note that when fscking tags with "index-pack --strict", this
is even worse. index-pack does not add a trailing
NUL-terminator after the object, so we may actually read
past the buffer and print uninitialized memory. Running
t5302 with valgrind does notice the bug for that reason.
