The old parse_arg(), when fed an argument
"refs/heads/a"master
parsed 'refs/heads/a' off of the front of the argument and considered
itself successful. It was only when parse_next_arg() tried to parse
the *next* argument that a problem was noticed. But in fact, the
definition of the input format requires arguments to be terminated by
SP or NUL, so *this* argument is already erroneous and parse_arg()
should diagnose the problem.
So teach parse_arg() to verify that C-quoted arguments are terminated
correctly. If not, emit a more specific error message.
There is no corresponding error case of a non-C-quoted argument that
is not terminated correctly, because the end of a non-quoted argument
is *by definition* a space or NUL, so there is no way to insert other
junk between the "end" of the argument and the argument terminator.
Adjust the tests to expect the new error message. Add a docstring to
the function, incorporating the comments that were formerly within the
function plus some added information.

The old version was passing (among other things)
update SP refs/heads/c NUL NUL 0{40} NUL
to "git update-ref -z --stdin" to test whether the old-value check for
c is working. But the <newvalue> is empty, which is a bit off the
beaten track.
So, to be sure that we are testing what we want to test, provide an
actual <newvalue> on the "update" line.

The test
stdin -z create ref fails with zero new value
actually passes an empty new value, not a zero new value. So rename
the test s/zero/empty/, and change the expected error from
fatal: create $c given zero new value
to
fatal: create $c missing <newvalue>
Of course, this makes the test fail now, because although "git
update-ref" tries to distinguish between these two errors, it does not
succeed in this situation. Fixing it is more than a one-liner, so
mark the test test_expect_failure for now. The failure will be fixed
later in this patch series.

The hunk header pattern 'cpp' is intended for C and C++ source code, but
it is actually not particularly useful for the latter, and even misses
some use-cases for the former.
The parts of the pattern have the following flaws:
- The first part matches an identifier followed immediately by a colon
and arbitrary text and is intended to reject goto labels and C++
access specifiers (public, private, protected). But this pattern also
rejects C++ constructs, which look like this:
MyClass::MyClass()
MyClass::~MyClass()
MyClass::Item MyClass::Find(...
- The second part matches an identifier followed by a list of qualified
names (i.e. identifiers separated by the C++ scope operator '::')
separated by space or '*' followed by an opening parenthesis (with
space between the tokens). It matches function declarations like
struct item* get_head(...
int Outer::Inner::Func(...
Since the pattern requires at least two identifiers, GNU-style
function definitions are ignored:
void
func(...
Moreover, since the pattern does not allow punctuation other than '*',
the following C++ constructs are not recognized:
. template definitions:
template<class T> int func(T arg)
. functions returning references:
const string& get_message()
. functions returning templated types:
vector<int> foo()
. operator definitions:
Value operator+(Value l, Value r)
- The third part of the pattern finally matches compound definitions.
But it forgets about unions and namespaces, and also skips single-line
definitions
struct random_iterator_tag {};
because no semicolon can occur on the line.
Change the first pattern to require a colon at the end of the line
(except for trailing space and comments), so that it does not reject
constructor or destructor definitions.
Notice that all interesting anchor points begin with an identifier or
keyword. But since there is a large variety of syntactical constructs
after the first "word", the simplest is to require only this word and
accept everything else. Therefore, this boils down to a line that begins
with a letter or underscore (optionally preceded by the C++ scope
operator '::' to accept functions returning a type anchored at the
global namespace). Replace the second and third part by a single pattern
that picks such a line.
This has the following desirable consequence:
- All constructs mentioned above are recognized.
and the following likely desirable consequences:
- Definitions of global variables and typedefs are recognized:
int num_entries = 0;
extern const char* help_text;
typedef basic_string<wchar_t> wstring;
- Commonly used marco-ized boilerplate code is recognized:
BEGIN_MESSAGE_MAP(CCanvas,CWnd)
Q_DECLARE_METATYPE(MyStruct)
PATTERNS("tex",...)
(The last one is from this very patch.)
but also the following possibly undesirable consequence:
- When a label is not on a line by itself (except for a comment) it is
no longer rejected, but can appear as a hunk header if it occurs at
the beginning of a line:
next:;
IMO, the benefits of the change outweigh the (possible) regressions by a
large margin.
