527ec39 (generate-cmdlist: parse common group commands, 2015-05-21)
replaced generate-cmdlist.sh with a more functional Perl version,
generate-cmdlist.perl. The Perl version gleans named tags from a new
"common groups" section in command-list.txt and recognizes those
tags in "command list" section entries in place of the old 'common'
tag. This allows git-help to, not only recognize, but also group
common commands.
Although the tests require Perl, 527ec39 creates an unconditional
dependence upon Perl in the build system itself, which can not be
overridden with NO_PERL. Such a dependency may be undesirable; for
instance, the 'git-lite' package in the FreeBSD ports tree is
intended as a minimal Git installation (which may, for example, be
useful on servers needing only local clone and update capability),
which, historically, has not depended upon Perl[1].
Therefore, revive generate-cmdlist.sh and extend it to recognize
"common groups" and its named tags. Retire generate-cmdlist.perl.

The rev-list command does not have the internal
infrastructure to display notes. Running:
git rev-list --notes HEAD
will silently ignore the "--notes" option. Running:
git rev-list --notes --grep=. HEAD
will crash on an assert. Running:
git rev-list --format=%N HEAD
will place a literal "%N" in the output (it does not even
expand to an empty string).
Let's have rev-list tell the user that it cannot fill the
user's request, rather than silently producing wrong data.
Likewise, let's remove mention of the notes options from the
rev-list documentation.

When we are running the git command "foo", we may have to
look up the config keys "pager.foo" and "alias.foo". These
config schemes are mis-designed, as the command names can be
anything, but the config syntax has some restrictions. For
example:
$ git foo_bar
error: invalid key: pager.foo_bar
error: invalid key: alias.foo_bar
git: 'foo_bar' is not a git command. See 'git --help'.
You cannot name an alias with an underscore. And if you have
an external command with one, you cannot configure its
pager.
In the long run, we may develop a different config scheme
for these features. But in the near term (and because we'll
need to support the existing scheme indefinitely), we should
at least squelch the error messages shown above.
These errors come from git_config_parse_key. Ideally we
would pass a "quiet" flag to the config machinery, but there
are many layers between the pager code and the key parsing.
Passing a flag through all of those would be an invasive
change.
Instead, let's provide a config function to report on
whether a key is syntactically valid, and have the pager and
alias code skip lookup for bogus keys. We can build this
easily around the existing git_config_parse_key, with two
minor modifications:
1. We now handle a NULL store_key, to validate but not
write out the normalized key.
2. We accept a "quiet" flag to avoid writing to stderr.
This doesn't need to be a full-blown public "flags"
field, because we can make the existing implementation
a static helper function, keeping the mess contained
inside config.c.

When looking for the start of the trailers in the message
we are passed, we should ignore the first line of the message.
The reason is that if we are passed a patch or commit message
then the first line should be the patch title.
If we are passed only trailers we can expect that they start
with an empty line that can be ignored too.
This way we can properly process commit messages that have
only one line with something that looks like a trailer, for
example like "area of code: change we made".

In read_sha1_file_extended we die if read_object fails with a fatal
error. We detect a fatal error if errno is non-zero and is not
ENOENT. If the object could not be read because it does not exist,
this is not considered a fatal error and we want to return NULL.
Somewhere down the line, read_object calls git_open_noatime to open
a pack index file, for example. We first try open with O_NOATIME.
If O_NOATIME fails with EPERM, we retry without O_NOATIME. When the
second open succeeds, errno is however still set to EPERM from the
first attempt. When we finally determine that the object does not
exist, read_object returns NULL and read_sha1_file_extended dies
with a fatal error:
fatal: failed to read object <sha1>: Operation not permitted
Fix this by resetting errno to zero before we call open again.

When we call "die(fmt, args...)", we end up in vreportf with
two pieces of information:
1. The prefix "fatal: "
2. The original fmt and va_list of args.
We format item (2) into a temporary buffer, and then fprintf
the prefix and the temporary buffer, along with a newline.
This has the unfortunate side effect of truncating any error
messages that are longer than 4096 bytes.
Instead, let's use separate calls for the prefix and
newline, letting us hand the item (2) directly to vfprintf.
This is essentially undoing d048a96 (print
warning/error/fatal messages in one shot, 2007-11-09), which
tried to have the whole output end up in a single `write`
call.
But we can address this instead by explicitly requesting
line-buffering for the output handle, and by making sure
that the buffer is empty before we start (so that outputting
the prefix does not cause a flush due to hitting the buffer
limit).
We may still break the output into two writes if the content
is larger than our buffer, but there's not much we can do
there; depending on the stdio implementation, that might
have happened even with a single fprintf call.

The vreportf function always goes to stderr, but run-command
wants child errors to go to the parent's original stderr. To
solve this, commit a5487dd duplicates the stderr fd and
installs die and error handlers to direct the output
appropriately (which later turned into the vwritef
function). This has two downsides, though:
- we make multiple calls to write(), which contradicts the
"write at once" logic from d048a96 (print
warning/error/fatal messages in one shot, 2007-11-09).
- the custom handlers basically duplicate the normal
handlers. They're only a few lines of code, but we
should not have to repeat the magic "exit(128)", for
example.
We can solve the first by using fdopen() on the duplicated
descriptor. We can't pass this to vreportf, but we could
introduce a new vreportf_to to handle it.
However, to fix the second problem, we instead introduce a
new "set_error_handle" function, which lets the normal
vreportf calls output to a handle besides stderr. Thus we
can get rid of our custom handlers entirely, and just ask
the regular handlers to output to our new descriptor.
And as vwritef has no more callers, it can just go away.

The loop in strbuf_read() uses xread() repeatedly while extending
the strbuf until the call returns zero. If the buffer is
sufficiently large to begin with, this results in xread()
returning the remainder of the file to the end (returning
non-zero), the loop extending the strbuf, and then making another
call to xread() to have it return zero.
By using read_in_full(), we can tell when the read reached the end
of file: when it returns less than was requested, it's eof. This
way we can avoid an extra iteration that allocates an extra 8kB
that is never used.

Commit 7e837c6 (clone: simplify string handling in
guess_dir_name(), 2015-07-09) changed clone to use
strip_suffix instead of hand-rolled pointer manipulation.
However, strip_suffix will strip from the end of a
NUL-terminated string, and we may have already stripped some
characters (like directory separators, or "/.git"). This
leads to commands like:
git clone host:foo.git/
failing to strip the ".git".
We must instead convert our pointer arithmetic into a
computed length and feed that to strip_suffix_mem, which will
then reduce the length further for us.
It would be nicer if we could drop the pointer manipulation
entirely, and just continually strip using strip_suffix. But
that doesn't quite work for two reasons:
1. The early suffixes we're stripping are not constant; we
need to look for is_dir_sep, which could be one of
several characters.
2. Mid-way through the stripping we compute the pointer
"start", which shows us the beginning of the pathname.
Which really give us two lengths to work with: the
offset from the start of the string, and from the start
of the path. By using pointers for the early part, we
can just compute the length from "start" when we need
it.

This reveals a few problems:
- cloning "foo.git/" does not properly remove the ".git";
this is a recent regression from 7e837c6 (clone:
simplify string handling in guess_dir_name(), 2015-07-09)
- likewise, cloning foo/.git does not seem to handle the
bare case (we should end up in foo.git, but we try to
use foo/.git on the local end), which also comes from
7e837c6.
- cloning the root is not very smart about URL parsing,
and usernames and port numbers may end up in the
directory name

The "-x" test-script option turns on the shell's "-x"
tracing, which can help show why a particular test is
failing. Unfortunately, this can create false negatives in
some tests if they invoke a shell function with its stderr
redirected. t5512.10 is such a test, as it does:
test_must_fail git ls-remote refs*master >actual 2>&1 &&
test_cmp exp actual
The "actual" file gets the "-x" trace for the test_must_fail
function, which prevents it from matching the expected
output.
There's no way to avoid this without managing the
trace flag inside each sub-function, which isn't really a
workable solution. But unless you specifically care about
t5512.10, we can work around it by enabling tracing only for
the specific tests we want.
You can already do:
./t5512-ls-remote.sh -x --verbose-only=16
to see the trace only for a specific test. But that doesn't
_disable_ the tracing in the other tests; it just sends it
to /dev/null. However, there's no point in generating a
trace that the user won't see, so we can simply disable
tracing whenever it doesn't have a matching verbose flag.
The normal case of just "./t5512-ls-remote.sh -x" stays the
same, as "-x" already implies "--verbose" (and
"--verbose-only" overrides "--verbose", which is why this
works at all). And for our test, we need only check
$verbose, as maybe_setup_verbose will have already
set that flag based on the $verbose_only list).
