Add "git show-ref" builtin command
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.
For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.
For example:
git show-ref master
will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").
When using the "--verify" flag, the command requires an exact ref path:
git show-ref --verify refs/heads/master
will only match the exact branch called "master".
If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.
For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like
git-show-ref --quiet --verify -- "refs/heads/$headname" ||
echo "$headname is not a valid branch"
to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).
To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).
To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do
git show-ref --tags --dereference
to get a listing of all tags together with what they dereference.

Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;

and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

peel_ref: do not return a null sha1
The idea of the peel_ref function is to dereference tag
objects recursively until we hit a non-tag, and return the
sha1. Conceptually, it should return 0 if it is successful
(and fill in the sha1), or -1 if there was nothing to peel.
However, the current behavior is much more confusing. For a
regular loose ref, the behavior is as described above. But
there is an optimization to reuse the peeled-ref value for a
ref that came from a packed-refs file. If we have such a
ref, we return its peeled value, even if that peeled value
is null (indicating that we know the ref definitely does
_not_ peel).
It might seem like such information is useful to the caller,
who would then know not to bother loading and trying to peel
the object. Except that they should not bother loading and
trying to peel the object _anyway_, because that fallback is
already handled by peel_ref. In other words, the whole point
of calling this function is that it handles those details
internally, and you either get a sha1, or you know that it
is not peel-able.
This patch catches the null sha1 case internally and
converts it into a -1 return value (i.e., there is nothing
to peel). This simplifies callers, which do not need to
bother checking themselves.
Two callers are worth noting:
- in pack-objects, a comment indicates that there is a
difference between non-peelable tags and unannotated
tags. But that is not the case (before or after this
patch). Whether you get a null sha1 has to do with
internal details of how peel_ref operated.
- in show-ref, if peel_ref returns a failure, the caller
tries to decide whether to try peeling manually based on
whether the REF_ISPACKED flag is set. But this doesn't
make any sense. If the flag is set, that does not
necessarily mean the ref came from a packed-refs file
with the "peeled" extension. But it doesn't matter,
because even if it didn't, there's no point in trying to
peel it ourselves, as peel_ref would already have done
so. In other words, the fallback peeling is guaranteed
to fail.

Add "git show-ref" builtin command
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.
For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.
For example:
git show-ref master
will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").
When using the "--verify" flag, the command requires an exact ref path:
git show-ref --verify refs/heads/master
will only match the exact branch called "master".
If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.
For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like
git-show-ref --quiet --verify -- "refs/heads/$headname" ||
echo "$headname is not a valid branch"
to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).
To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).
To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do
git show-ref --tags --dereference
to get a listing of all tags together with what they dereference.

Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl
