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.

In the final test of t0001, we have a repo whose .git is a
symlink to a directory "here", and we use
"--separate-git-dir" to migrate that to a .git file pointing
to a different directory. We check that the data is migrated
to the new directory and that .git looks like a git-file.
We also check that "here" is not a directory, which is
slightly misleading. It should not be a directory, but
neither should it be gone. It is the actual resting place of
the git-file, and .git remains a symlink to it.
Let's check that more explicitly, both to make our test more
robust, and to make further cleanups in this area more
obvious.

Doing:
GIT_CONFIG=foo git config ...
is equivalent to:
git config --file=foo ...
The latter is easier to read and slightly less error-prone,
because of issues with one-shot variables and shell
functions (e.g., you cannot use the former with
test_must_fail).
Note that we explicitly leave one case in t1300 which checks
the same operation on both GIT_CONFIG and "git config
--file". They are equivalent in the code these days, but
this will make sure it remains so.

Some tests want to check or set config in another
repository. E.g., t1000 creates repositories and makes sure
that their core.bare and core.worktree settings are what we
expect. We can do this with:
GIT_CONFIG=$repo/.git/config git config ...
but it better shows the intent to just enter the repository
and let "git config" do the normal lookups:
(cd $repo && git config ...)
In theory, this would cause us to use an extra subshell, but
in all such cases, we are actually already in a subshell.

Several test scripts manually unset GIT_CONFIG and other
GIT_* variables. These are generally taken care of for us by
test-lib.sh already.
Unsetting these is not only useless, but can be confusing to
a reader, who may wonder why some tests in a script unset
them and others do not (t0001 is particularly guilty of this
inconsistency, probably because many of its tests predate
the test-lib.sh environment-cleansing).
Note that we cannot always get rid of such unsetting. For
example, t9130 can drop the GIT_CONFIG unset, but not the
GIT_DIR one, because lib-git-svn.sh sets the latter. And in
t1000, we unset GIT_TEMPLATE_DIR, which is explicitly
initialized by test-lib.sh.

Once upon a time, the setting of GIT_CONFIG in the

setting config variables with an alternative GIT_CONFIG,
2006-06-20) unconditionally set GIT_CONFIG in the Makefile
when running tests to give us a known starting point.
This is insufficient for running the tests outside of the
Makefile, however, and 8565d2d (Make tests independent of
global config files, 2007-02-15) later set GIT_CONFIG
directly in test-lib.sh. At that point the Makefile setting
was redundant, but we never removed it. Let's do so now.

On MINGW, "pwd" is defined as "pwd -W" in test-lib.sh. This usually is the

no need to use an absolute path in the first place, so get rid of it.
This was discovered in the context of the mingwGitDevEnv project and only
did not surface before with msysgit because the latter does not ship

Ordinarily, we would say "VAR=VAL command" to execute a tested
command with environment variable(s) set only for that command.
This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.
To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:
(
VAR=VAL && export VAR &&
test_must_fail git command to be tested
)
But with "env" utility, we should be able to say:
test_must_fail env VAR=VAL git command to be tested
which is much shorter and easier to read.
