The add_extra_ref() interface is used to add an extra-ref that is _not_
our ref for the purpose of helping auto-following of tags and reducing
object transfer from remote repository, and they are typically formatted
as a tagname followed by ^{} to make sure no valid refs match that
pattern. In other words, these entries are deliberately formatted not to
pass check-refname-format test.
A recent series however added a test unconditionally to the add_ref()
function that is called from add_extra_ref(). The check may be sensible
for other two callsites of the add_ref() interface, but definitely is
a wrong thing to do in add_extra_ref(). Disable it.

resolve_ref() may return a pointer to a static buffer, which is not
safe for long-term use because if another resolve_ref() call happens,
the buffer may be changed. Many call sites though do not care about
this buffer. They simply check if the return value is NULL or not.
Convert all these call sites to new wrappers to reduce resolve_ref()
calls from 57 to 34. If we change resolve_ref() prototype later on
to avoid passing static buffer out, this helps reduce changes.

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".
When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.
Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.
So for the same reason as we added rule to allow "git fetch $there v1.0"
instead of "git fetch $there tags/v1.0" in the previous commit, here is a
bit longer rope for the users, which incidentally simplifies our code.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
You can already do so with "git fetch $there tags/v1.0" but if it is not
ambiguous there is no reason to force users to type more.

629cd3a (resolve_ref(): emit warnings for improperly-formatted references,
2011-09-15) made resolve_ref() warn against files that are found in the
directories the ref dwimmery looks at. The intent may be good, but these
messages come from a wrong level of the API hierarchy.
Instead record the breakage in "flags" whose purpose is to explain the
result of the function to the caller, who is in a much better position to
make intelligent decision based on the information.
This updates sha1_name.c::dwim_ref() to warn against such a broken
candidate only when it does not appear directly below $GIT_DIR to restore
the traditional behaviour, as we know many files directly underneath
$GIT_DIR/ are not refs.
Warning against "git show config --" with "$GIT_DIR/config does not look
like a well-formed ref" does not make sense, and we may later tweak the
dwimmery not to even consider them as candidates, but that is a longer
term topic.

Instead of keeping this as an internal API, let the callers find
out the reason why resolve_ref() returned NULL is not because there

This reverts commit 2f6af3820eb61f30cf102b345d35028047300b74; we shouldn't
be changing the traditional behaviour without devising a proper transtion
plan only to hastily fix fallouts on the master branch.

2c5c66b (Merge branch 'jp/get-ref-dir-unsorted', 2011-10-10) merged a
topic that forked from the mainline before a new helper function
get_packed_refs() refactored code to read packed-refs file. The merge made
the call to the helper function with an incorrect argument. The parameter
to the function has to be a path to the submodule.
