match_refs() returns non-zero if there is an error in
match_explicit_refs(), without handling any remaining pattern ref specs.
Its existing callers exit upon receiving non-zero, so a partial result
is of no consequence to them; however a new caller, builtin-remote, is
interested in the complete result even if there are errors in
match_explicit_refs().

In some instances, match_refs() sets the peer_ref field of refs in the
dst list such that it points to a ref in the src list. This prevents
callers from freeing both the src and dst lists, as doing so would cause
a double-free since free_refs() frees the peer_ref.
As well, the following configuration causes two refs in the dst list to
have the same peer_ref, which can also lead to a double-free:
push = refs/heads/master:refs/heads/backup
push = refs/heads/master:refs/heads/master
Existing callers of match_heads() call it only once and then terminate,
w/o ever bothering to free the src or dst lists, so this is not
currently a problem.
This patch modifies match_refs() to first copy any refs it plucks from
the src list before assigning them as a peer_ref. This allows
builtin-remote, a future caller, to free the src and dst lists.

Determining HEAD is ambiguous since it is done by comparing SHA1s.
In the case of multiple matches we return refs/heads/master if it
matches, else we return the first match we encounter. builtin-remote
needs all matches returned to it, so add a flag for it to request such.
To be simple and consistent, the return value is now a copy (including
peer_ref) of the matching refs.

To ensure that copied refs can always be freed w/o causing a
double-free, make copy_ref() perform a deep copy.
Also have copy_ref() return NULL if asked to copy NULL to simplify
things for the caller.
Background: currently copy_ref() performs a shallow copy. This is fine
for current callers who never free the result and/or only copy refs
which contain NULL pointers. But copy_ref() is about to gain a new
caller (guess_remote_head()) which copies refs where peer_ref is not
NULL and the caller of guess_remote_head() will want to free the result.

This function had complications which made it hard to extend.
- It used to do two things: find the HEAD ref, and then find a
matching ref, optionally returning the former via assignment to a
passed-in pointer. Since finding HEAD is a one-liner, just have a
caller do it themselves and pass it as an argument.
- It used to manually search through the ref list for
refs/heads/master; this can be a one-line call to
find_ref_by_name.

ref_newer() appears to have been copied from builtin-send-pack.c to
http-push.c via cut and paste. This patch moves the function and its
helper unmark_and_free() to remote.c. There was a slight difference
between the two implementations, one used TMP_MARK for the mark, the
other used 1. Per Jeff King, I went with TMP_MARK as more correct.

Current git versions ignore everything after # (called <head> in the

In three cases in remote.c, a "raw" ref is allocated using alloc_ref()
and then its is constructed using sprintf(). Clean it up by adding a
helper function, alloc_ref_with_prefix(), which creates a composite

A wildcard refspec is internally parsed into a refspec structure with src
and dst strings. Many parts of the code assumed that these do not include
the trailing "/*" when matching the wildcard pattern with an actual ref we
see at the remote. What this meant was that we needed to make sure not
just that the prefix matched, and also that a slash followed the part that
matched.
But a codepath that scans the result from ls-remote and finds matching
refs forgot to check the "matching part must be followed by a slash" rule.
This resulted in "refs/heads/b1" from the remote side to mistakenly match
the source side of "refs/heads/b/*:refs/remotes/b/*" refspec.
Worse, the refspec crafted internally by "git-clone", and a hardcoded
preparsed refspec that is used to implement "git-fetch --tags", violated
this "parsed widcard refspec does not end with slash" rule; simply adding
the "matching part must be followed by a slash" rule then would have
broken codepaths that use these refspecs.
This commit changes the rule to require a trailing slash to parsed
wildcard refspecs. IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as
src = "refs/heads/b/" and dst = "refs/remotes/b/". This allows us to
simplify the matching logic because we only need to do a prefixcmp() to
notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

The message length depends on the length of the branch name. In my case,
the branch name "origin/add-chickens2" put the first line of the "your

People seem to like "Your branch is ahead by N commit" report made by
"git checkout", but the interface into the statistics function was a bit
clunky. This splits the function into three parts:
* The core "commit counting" function that takes "struct branch" and
returns number of commits to show if we are ahead, behind or forked;
* Convenience "stat formating" function that takes "struct branch" and
formats the report into a given strbuf, using the above function;
* "checkout" specific function that takes "branch_info" (type that is
internal to checkout implementation), calls the above function and
print the formatted result.
in the hope that the former two can be more easily reusable.

match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

Previously, a push like:
git push remote src:dst
would go through the following steps:
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

We tightened the refspec validation code in an earlier commit ef00d15
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.
This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).
This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:
