http-push: refactor parsing of remote object names
We get loose object names like "objects/??/..." from the
remote side, and need to convert them to their hex
representation.
The code to do so is rather hard to follow, as it uses some
calculated lengths whose origins are hard to understand and
verify (e.g., the path must be exactly 49 characters long.
why? Why doesn't the strcpy overflow obj_hex, which is the
same length as path?).
We can simplify this a bit by using skip_prefix, using standard
40- and 20-character buffers for hex and binary sha1s, and
adding some comments.
We also drop a totally bogus comment that claims strlcpy
cannot be used because "path" is not NUL-terminated. Right
between a call to strlen(path) and strcpy(path).

In some cases, we use starts_with to check for a prefix, and

After handling options, any leftover arguments should be
commands. However, we pass through "--help" and "--version",
so that we convert them into "git help" and "git version"
respectively.
This is a straightforward use of skip_prefix to avoid a

comment to explain this otherwise confusing behavior.

There are several uses of the magic number "line+45" when
parsing ACK lines from the server, and it's rather unclear
why 45 is the correct number. We can make this more clear by
keeping a running pointer as we parse, using skip_prefix to
jump past the first "ACK ", then adding 40 to jump past
get_sha1_hex (which is still magical, but hopefully 40 is
less magical to readers of git code).
Note that this actually puts us at line+44. The original
required some character between the sha1 and further ACK
flags (it is supposed to be a space, but we never enforced
that). We start our search for flags at line+44, which
meanas we are slightly more liberal than the old code.

When we see a file change in a commit, we expect one of:
1. A mark.
2. An "inline" keyword.
3. An object sha1.
The handling of spaces is inconsistent between the three
options. Option 1 calls a sub-function which checks for the
space, but doesn't parse past it. Option 2 parses the space,
then deliberately avoids moving the pointer past it. Option
3 detects the space locally but doesn't move past it.
This is confusing, because it looks like option 1 forgets to
check for the space (it's just buried). And option 2 checks
for "inline ", but only moves strlen("inline") characters
forward, which looks like a bug but isn't.
We can make this more clear by just having each branch move
past the space as it is checked (and we can replace the
doubled use of "inline" with a call to skip_prefix).

As in earlier commits, the diff option parser uses
starts_with to find that an argument starts with "--stat-",
and then adds strlen("stat-") to find the rest of the
option.
However, in this case the starts_with and the strlen are
separated across functions, making it easy to call the
latter without the former. Let's use skip_prefix instead of
raw pointer arithmetic to catch such a case.

Like earlier cases, we can use skip_prefix to avoid magic
numbers that must match the length of starts_with prefixes.

Fast-import does a lot of parsing of commands and
dispatching to sub-functions. For example, given "option
foo", we might recognize "option " using starts_with, and
then hand it off to parse_option() to do the rest.
However, we do not let parse_option know that we have parsed
the first part already. It gets the full buffer, and has to
skip past the uninteresting bits. Some functions simply add
a magic constant:
All of these are brittle and easy to get wrong (especially
given that the starts_with call and the code that assumes
the presence of the prefix are far apart). Instead, we can
use skip_prefix, and just pass each handler a pointer to its
arguments.

It's a common idiom to match a prefix and then skip past it
with a magic number, like:
if (starts_with(foo, "bar"))
foo += 3;
This is easy to get wrong, since you have to count the
prefix string yourself, and there's no compiler check if the
string changes. We can use skip_prefix to avoid the magic
numbers here.
Note that some of these conversions could be much shorter.
For example:
if (starts_with(arg, "--foo=")) {
bar = arg + 6;
continue;
}
could become:
if (skip_prefix(arg, "--foo=", &bar))
continue;
However, I have left it as:
if (skip_prefix(arg, "--foo=", &v)) {
bar = v;
continue;
}
to visually match nearby cases which need to actually
process the string. Like:
if (skip_prefix(arg, "--foo=", &v)) {
bar = atoi(v);
continue;

transport-helper: avoid reading past end-of-string
We detect the "import-marks" capability by looking for that
string, but _without_ a trailing space. Then we skip past it
using strlen("import-marks "), with a space. So if a remote
helper gives us exactly "import-marks", we will read past
the end-of-string by one character.
This is unlikely to be a problem in practice, because such
input is malformed in the first place, and because there is
a good chance that the string has an extra NUL terminator
one character after the original (because it formerly had a
newline in it that we parsed off).
We can fix it by using skip_prefix with "import-marks ",
with the space. The other form appears to be a typo from a515ebe (transport-helper: implement marks location as
capability, 2011-07-16); "import-marks" has never existed
without an argument, and it should match the "export-marks"
definition above.
Speaking of which, we can also use skip_prefix in a few
other places while we are in the function.

fast-import: fix read of uninitialized argv memory
Fast-import shares code between its command-line parser and
the "option" command. To do so, it strips the "--" from any
command-line options and passes them to the option parser.
However, it does not confirm that the option even begins
with "--" before blindly passing "arg + 2".
It does confirm that the option starts with "-", so the only
affected case was:
git fast-import -
which would read uninitialized memory after the argument. We
can fix it by using skip_prefix and checking the result. As
a bonus, this gets rid of some magic numbers.

we will parse the "bogus" portion. Our parser assumes that
the buffer starts with "Subproject commit", and blindly
skips past it using strlen(). This can cause us to read
random memory after the buffer.
This problem was unlikely to have come up in practice (since
it requires a malformed diff), and even when it did, we
likely noticed the problem anyway as the next operation was
to call get_sha1_hex on the random memory.
However, we can easily fix it by using skip_prefix to notice
the parsing error.

The skip_prefix() function returns a pointer to the content
past the prefix, or NULL if the prefix was not found. While
this is nice and simple, in practice it makes it hard to use
for two reasons:
1. When you want to conditionally skip or keep the string
as-is, you have to introduce a temporary variable.
For example:
tmp = skip_prefix(buf, "foo");
if (tmp)
buf = tmp;
2. It is verbose to check the outcome in a conditional, as
you need extra parentheses to silence compiler
warnings. For example:
if ((cp = skip_prefix(buf, "foo"))
/* do something with cp */
Both of these make it harder to use for long if-chains, and
we tend to use starts_with() instead. However, the first line
of "do something" is often to then skip forward in buf past
the prefix, either using a magic constant or with an extra
strlen(3) (which is generally computed at compile time, but
means we are repeating ourselves).
This patch refactors skip_prefix() to return a simple boolean,
and to provide the pointer value as an out-parameter. If the
prefix is not found, the out-parameter is untouched. This
lets you write:
if (skip_prefix(arg, "foo ", &arg))
do_foo(arg);
else if (skip_prefix(arg, "bar ", &arg))
do_bar(arg);

We often represent our strings as a counted string, i.e. a pair of
the pointer to the beginning of the string and its length, and the
string may not be NUL terminated to that length.
To compare a pair of such counted strings, unpack-trees.c and
read-cache.c implement their own name_compare() functions
identically. In addition, the cache_name_compare() function in
read-cache.c is nearly identical. The only difference is when one
string is the prefix of the other string, in which case
name_compare() returns -1/+1 to show which one is longer, and
cache_name_compare() returns the difference of the lengths to show
the same information.
Unify these three functions by using the implementation from
cache_name_compare(). This does not make any difference to the
existing and future callers, as they must be paying attention only
to the sign of the returned value (and not the magnitude) because
the original implementations of these two functions return values
returned by memcmp(3) when the one string is not a prefix of the
other string, and the only thing memcmp(3) guarantees its callers is
the sign of the returned value, not the magnitude.

break out of the loop if any single iteration fails, we use
a subshell/exit like:
(
for i in $stuff
do
do-something $i || exit 1

)
However, we are inconsistent in our loop body. Some commands
get their own "|| exit 1", and others try to chain to the
next command with "&&", like:
X &&
Y || exit 1
Z || exit 1
This is a little hard to read and follow, because X and Y
are treated differently for no good reason. But much worse,
the second loop follows a similar pattern and gets it wrong.
"Y" is expected to fail, so we use "&& exit 1", giving us:
X &&
Y && exit 1
Z || exit 1
That gets the test for X wrong (we do not exit unless both X
fails and Y unexpectedly succeeds, but we would want to exit
if _either_ is wrong). We can write this clearly and

"|| exit 1", and negating Y with "!" (as we would in a

If git rebase --merge encountered a conflict, --skip would not work if the
next commit also conflicted. The msgnum file would never be updated with
the new patch number, so no patch would actually be skipped, resulting in an
inescapable loop.
Update the msgnum file's value as the first thing in call_merge. This also
avoids an "Already applied" message when skipping a commit. There is no
visible change for the other contexts in which call_merge is invoked, as the
msgnum file's value remains unchanged in those situations.

Allow specifying only certain individual test pieces to be run
using a range notation (e.g. "t1234-test.sh --run='1-4 6 8 9-'").
* ib/test-selectively-run:
t0000-*.sh: fix the GIT_SKIP_TESTS sub-tests
test-lib: '--run' to run only specific tests
test-lib: tests skipped by GIT_SKIP_TESTS say so
test-lib: document short options in t/README
Allow remote-helper/fast-import based transport to rename the refs
while transferring the history.
* fc/remote-helper-refmap:
transport-helper: remove unnecessary strbuf resets
transport-helper: add support to delete branches
fast-export: add support to delete refs
fast-import: add support to delete refs
transport-helper: add support to push symbolic refs
transport-helper: add support for old:new refspec
fast-export: add new --refspec option
fast-export: improve argument parsing
"git gc --auto" was recently changed to run in the background to
give control back early to the end-user sitting in front of the
terminal, but it forgot that housekeeping involving reflogs should
be done without other processes competing for accesses to the refs.
* nd/daemonize-gc:
gc --auto: do not lock refs in the background
"git remote rm" and "git remote prune" can involve removing many
refs at once, which is not a very efficient thing to do when very
many refs exist in the packed-refs file.
* jl/remote-rm-prune:
remote prune: optimize "dangling symref" check/warning
remote: repack packed-refs once when deleting multiple refs
remote rm: delete remote configuration as the last
The completion code did not know about quite a few options that are
common between "git merge" and "git pull", and a couple of options
unique to "git merge".
* jk/complete-merge-pull:
completion: add missing options for git-merge
completion: add a note that merge options are shared
