index-pack: detect local corruption in collision check
When we notice that we have a local copy of an incoming
object, we compare the two objects to make sure we haven't
found a collision. Before we get to the actual object
bytes, though, we compare the type and size from
sha1_object_info().
If our local object is corrupted, then the type will be
OBJ_BAD, which obviously will not match the incoming type,
and we'll report "SHA1 COLLISION FOUND" (with capital
letters and everything). This is confusing, as the problem
is not a collision but rather local corruption. We should
report that instead (just like we do if reading the rest of
the object content fails a few lines later).
Note that we _could_ just ignore the error and mark it as a
non-collision. That would let you "git fetch" to replace a
corrupted object. But it's not a very reliable method for
repairing a repository. The earlier want/have negotiation
tries to get the other side to omit objects we already have,
and it would not realize that we are "missing" this
corrupted object. So we're better off complaining loudly
when we see corruption, and letting the user take more
drastic measures to repair (like making a full clone
elsewhere and copying the pack into place).
Note that the test sets transfer.unpackLimit in the
receiving repository so that we use index-pack (which is
what does the collision check). Normally for such a small
push we'd use unpack-objects, which would simply try to
write the loose object, and discard the new one when we see
that there's already an old one.

sha1_loose_object_info: return error for corrupted objects
When sha1_loose_object_info() finds that a loose object file
cannot be stat(2)ed or mmap(2)ed, it returns -1 to signal an
error to the caller. However, if it found that the loose
object file is corrupt and the object data cannot be used
from it, it stuffs OBJ_BAD into "type" field of the
object_info, but returns zero (i.e., success), which can
confuse callers.
This is due to
052fe5eac (sha1_loose_object_info: make type
lookup optional, 2013-07-12), which switched the return to a
strict success/error, rather than returning the type (but
botched the return).
Callers of regular sha1_object_info() don't notice the
difference, as that function returns the type (which is
OBJ_BAD in this case). However, direct callers of
sha1_object_info_extended() see the function return success,
but without setting any meaningful values in the object_info
struct, leading them to access potentially uninitialized
memory.
The easiest way to see the bug is via "cat-file -s", which
will happily ignore the corruption and report whatever
value happened to be in the "size" variable.

avoid using mksnpath for refs
Like the previous commit, we'd like to avoid the assumption

1. It quietly writes "/bad-path/" when truncation occurs.
This saves the caller having to check the error code,
but if you aren't actually feeding the result to a
system call (and we aren't here), it's questionable.
2. It calls cleanup_path(), which removes leading
instances of "./". That's questionable when dealing
with refnames, as we could silently canonicalize a
syntactically bogus refname into a valid one.

diff: avoid fixed-size buffer for patch-ids
To generate a patch id, we format the diff header into a
fixed-size buffer, and then feed the result to our sha1
computation. The fixed buffer has size '4*PATH_MAX + 20',
which in theory accommodates the four filenames plus some
extra data. Except:
1. The filenames may not be constrained to PATH_MAX. The
static value may not be a real limit on the current
filesystem. Moreover, we may compute patch-ids for
names stored only in git, without touching the current
filesystem at all.
2. The 20 bytes is not nearly enough to cover the
extra content we put in the buffer.
As a result, the data we feed to the sha1 computation may be
truncated, and it's possible that a commit with a very long
filename could erroneously collide in the patch-id space
with another commit. For instance, if one commit modified
"really-long-filename/foo" and another modified "bar" in the
same directory.
In practice this is unlikely. Because the filenames are
repeated, and because there's a single cutoff at the end of
the buffer, the offending filename would have to be on the
order of four times larger than PATH_MAX.
We could fix this by moving to a strbuf. However, we can
observe that the purpose of formatting this in the first
place is to feed it to git_SHA1_Update(). So instead, let's
just feed each part of the formatted string directly. This
actually ends up more readable, and we can even factor out
some duplicated bits from the various conditional branches.
Technically this may change the output of patch-id for very
long filenames, but it's not worth making an exception for
this in the --stable output. It was a bug, and one that only
affected an unlikely set of paths. And anyway, the exact
value would have varied from platform to platform depending
on the value of PATH_MAX, so there is no "stable" value.

Makefile: detect errors in running spatch
The "make coccicheck" target runs spatch against each source
file. But it does so in a for loop, so "make" never sees the
exit code of spatch. Worse, it redirects stderr to a log
file, so the user has no indication of any failure. And then
to top it all off, because we touched the patch file's
mtime, make will refuse to repeat the command because it
think the target is up-to-date.
So for example:
$ make coccicheck SPATCH=does-not-exist
SPATCH contrib/coccinelle/free.cocci
SPATCH contrib/coccinelle/qsort.cocci
SPATCH contrib/coccinelle/xstrdup_or_null.cocci
SPATCH contrib/coccinelle/swap.cocci
SPATCH contrib/coccinelle/strbuf.cocci
SPATCH contrib/coccinelle/object_id.cocci
SPATCH contrib/coccinelle/array.cocci
$ make coccicheck SPATCH=does-not-exist
make: Nothing to be done for 'coccicheck'.
With this patch, you get:
$ make coccicheck SPATCH=does-not-exist
SPATCH contrib/coccinelle/free.cocci
/bin/sh: 4: does-not-exist: not found
Makefile:2338: recipe for target 'contrib/coccinelle/free.cocci.patch' failed

odb_mkstemp: write filename into strbuf
The odb_mkstemp() function expects the caller to provide a
fixed buffer to write the resulting tempfile name into. But
it creates the template using snprintf without checking the
return value. This means we could silently truncate the
filename.
In practice, it's unlikely that the truncation would end in
the template-pattern that mkstemp needs to open the file. So
we'd probably end up failing either way, unless the path was
specially crafted.
The simplest fix would be to notice the truncation and die.
However, we can observe that most callers immediately
xstrdup() the result anyway. So instead, let's switch to
using a strbuf, which is easier for them (and isn't a big
deal for the other 2 callers, who can just strbuf_release
when they're done with it).
Note that many of the callers used static buffers, but this
was purely to avoid putting a large buffer on the stack. We
never passed the static buffers out of the function, so
there's no complicated memory handling we need to change.

do not check odb_mkstemp return value for errors
The odb_mkstemp function does not return an error; it dies
on failure instead. But many of its callers compare the
resulting descriptor against -1 and die themselves.
Mostly this is just pointless, but it does raise a question
when looking at the callers: if they show the results of the
"template" buffer after a failure, what's in it? The answer
is: it doesn't matter, because it cannot happen.
So let's make that clear by removing the bogus error checks.
In bitmap_writer_finish(), we can drop the error-handling
code entirely. In the other two cases, it's shared with the
open() in another code path; we can just move the
error-check next to that open() call.
And while we're at it, let's flesh out the function's
docstring a bit to make the error behavior clear.

travis-ci: build and test Git on Windows
Most Git developers work on Linux and they have no way to know if their
changes would break the Git for Windows build. Let's fix that by adding
a job to TravisCI that builds and tests Git on Windows. Unfortunately,
TravisCI does not support Windows.
Therefore, we did the following:
* Johannes Schindelin set up a Visual Studio Team Services build
sponsored by Microsoft and made it accessible via an Azure Function
that speaks a super-simple API. We made TravisCI use this API to
trigger a build, wait until its completion, and print the build and
test results.
* A Windows build and test run takes up to 3h and TravisCI has a timeout
after 50min for Open Source projects. Since the TravisCI job does not
use heavy CPU/memory/etc. resources, the friendly TravisCI folks
extended the job timeout for git/git to 3h.
Things, that would need to be done:
* Someone with write access to https://travis-ci.org/git/git would need
to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI
repository setting [1]. Afterwards the build should just work.
Things, that might need to be done:
* The Windows box can only process a single build at a time. A second
Windows build would need to wait until the first finishes. This
waiting time and the build time after the wait could exceed the 3h
threshold. If this is a problem, then it is likely to happen every day
as usually multiple branches are pushed at the same time (pu/next/
master/maint). I cannot test this as my TravisCI account has the 50min
timeout. One solution could be to limit the number of concurrent
TravisCI jobs [2].

builtin/receive-pack: fix incorrect pointer arithmetic
If we had already processed the last newline in a push certificate, we
would end up subtracting NULL from the end-of-certificate pointer when
computing the length of the line. This would have resulted in an
absurdly large length, and possibly a buffer overflow. Instead,
subtract the beginning-of-certificate pointer from the
end-of-certificate pointer, which is what's expected.
Note that this situation should never occur, since not only do we
require the certificate to be newline terminated, but the signature will
only be read from the beginning of a line. Nevertheless, it seems

notes: do not break note_tree structure in note_tree_consolidate()
After a note is removed, note_tree_consolidate is called to eliminate
some useless nodes. The typical case is that if you had an int_node
with 2 PTR_TYPE_NOTEs in it, and remove one of them, then the
PTR_TYPE_INTERNAL pointer in the parent tree can be replaced with the
remaining PTR_TYPE_NOTE.
This works fine when PTR_TYPE_NOTEs are involved, but falls flat when
other types are involved.
To put things in more practical terms, let's say we start from an empty
notes tree, and add 3 notes:
- one for a sha1 that starts with 424
- one for a sha1 that starts with 428
- one for a sha1 that starts with 4c
To keep track of this, note_tree.root will have a PTR_TYPE_INTERNAL at
a[4], pointing to an int_node*.
In turn, that int_node* will have a PTR_TYPE_NOTE at a[0xc], pointing to
the leaf_node* with the key and value, and a PTR_TYPE_INTERNAL at a[2],
pointing to another int_node*.
That other int_node* will have 2 PTR_TYPE_NOTE, one at a[4] and the
other at a[8].
When looking for the note for the sha1 starting with 428, get_note() will
recurse through (simplified) root.a[4].a[2].a[8].
Now, if we remove the note for the sha1 that starts with 4c, we're left
with a int_node* with only one PTR_TYPE_INTERNAL entry in it. After
note_tree_consolidate runs, root.a[4] now points to what used to be
pointed at by root.a[4].a[2].
Which means looking up for the note for the sha1 starting with 428 now
fails because there is nothing at root.a[4].a[2] anymore: there is only
root.a[4].a[4] and root.a[4].a[8], which don't match the expected
structure for the lookup.
So if all there is left in an int_node* is a PTR_TYPE_INTERNAL pointer,
we can't safely remove it. I think the same applies for PTR_TYPE_SUBTREE
pointers. IOW, only PTR_TYPE_NOTEs are safe to be moved to the parent
int_node*.
This doesn't have a practical effect on git because all that happens
after a remove_note is a write_notes_tree, which just iterates the entire
note tree, but this affects anything using libgit.a that would try to do
lookups after removing notes.

sequencer: allow the commit-msg hooks to run during a `reword`
The `reword` command used to call `git commit` in a manner that asks for
the prepare-commit-msg and commit-msg hooks to do their thing.
Converting that part of the interactive rebase to C code introduced the
regression where those hooks were no longer run.
Let's fix this.
Note: the flag is called `VERIFY_MSG` instead of the more intuitive
`RUN_COMMIT_MSG_HOOKS` to indicate that the flag suppresses the
`--no-verify` flag (which may do other things in the future in addition
to suppressing the commit message hooks, too).

sequencer: make commit options more extensible
So far every time we need to tweak the behaviour of run_git_commit()
we have been adding a "int" parameter to it. As the function gains
parameters and different callsites having different needs, this is
becoming a maintenance burden. When a new knob needs to be added to
address a specific need for a single callsite, all the other callsites
need to add a "no, I do not want anything special with respect to the
new knob" argument.
Consolidate the existing four parameters into a flag word to make it
more maintainable, as we will be adding a new one to the mix soon.
