When writing objects/info/packs, we use the basename of each pack

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

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

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

- 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.

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
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

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

progress: break too long progress bar lines
Some of the recently added progress indicators have quite long titles,
which might be even longer when translated to some languages, and when
they are shown while operating on bigger repositories, then the
progress bar grows longer than the default 80 column terminal width.
When the progress bar exceeds the width of the terminal it gets
line-wrapped, and after that the CR at the end doesn't return to the
beginning of the progress bar, but to the first column of its last
line. Consequently, the first line of the previously shown progress
bar is not overwritten by the next, and we end up with a bunch of
truncated progress bar lines scrolling past:
$ LANG=es_ES.UTF-8 git commit-graph write

Encontrando commits para commit graph entre los objetos empaquetados: 4% (2633
Encontrando commits para commit graph entre los objetos empaquetados: 5% (3292
[...]
Prevent this by breaking progress bars after the title once they
exceed the width of the terminal, so the counter and optional
percentage and throughput, i.e. all changing parts, are on the last
line. Subsequent updates will from then on only refresh the changing
parts, but not the title, and it will look like this:
$ LANG=es_ES.UTF-8 ~/src/git/git commit-graph write

Escribiendo commit graph en 4 pasos: 100% (

3298820), listo.
Note that the number of columns in the terminal is cached by
term_columns(), so this might not kick in when it should when a
terminal window is resized while the operation is running.
Furthermore, this change won't help if the terminal is so narrow that
the counters don't fit on one line, but I would put this in the "If it

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.

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

2015-03-08), code was added to read back the untracked cache from an
index extension.
Probably in the endeavor to avoid the `calloc()` implied by
`FLEX_ALLOC_STR()` (it is hard to know why exactly, the commit message
of that commit is a bit parsimonious with information), it calls
`malloc()` manually and then `memcpy()`s the bits and pieces into place.
It allocates the size of `struct untracked_cache_dir` plus the string
length of the untracked file name, then copies the information in two
steps: first the fixed-size metadata, then the name. And here lies the
rub: it includes the trailing NUL byte in the name.
If `FLEX_ARRAY` is defined as 0, this results in a buffer overrun.
To fix this, let's just add 1, for the trailing NUL byte. Technically,
this overallocates on platforms where `FLEX_ARRAY` is 1, but it should
not matter much in reality, as `malloc()` usually overallocates anyway,
unless the size to allocate aligns exactly with some internal chunk size
(see below for more on that).
The real strange thing is that neither valgrind nor DrMemory catches
this bug. In this developer's tests, a `memcpy()` (but not a
`memset()`!) could write up to 4 bytes after the allocated memory range
before valgrind would start reporting an issue.
However, when running Git built with nedmalloc as allocator, under rare
conditions (and inconsistently at that), this bug triggered an `abort()`
because nedmalloc rounds up the size to be `malloc()`ed to a multiple of
a certain chunk size, then adds a few bytes to be used for storing some
internal state. If there is no rounding up to do (because the size is
already a multiple of that chunk size), and if the buffer is overrun as
in the code patched in this commit, the internal state is corrupted.
The scenario that triggered this here bug fix entailed a git.git
checkout with an extra copy of the source code in an untracked
subdirectory, meaning that there was an untracked subdirectory called
"thunderbird-patch-inline" whose name's length is exactly 24 bytes,
which, added to the size of above-mentioned `struct untracked_cache_dir`
that weighs in with 104 bytes on a 64-bit system, amounts to 128,
aligning perfectly with nedmalloc's chunk size.
As there is no obvious way to trigger this bug reliably, on all
platforms supported by Git, and as the bug is obvious enough, this patch
comes without a regression test.

Documentation/git-show-branch: avoid literal {apostrophe}
The {apostrophe} was needed at the time of
a521845800 ("Documentation:
remove stray backslash in show-branch discussion", 2010-08-20). All
other uses of {apostrophe} were removed in
6cf378f0cb ("docs: stop using
asciidoc no-inline-literal", 2012-04-26).
Unfortunately, the {apostrophe} is rendered literally with Asciidoctor
(at least with 1.5.5-2.0.3). Avoid this by using single-quotes.
Escaping the leading single-quote allows the content to render properly
in AsciiDoc and Asciidoctor.
