Our usual method for determining the ref pointed to by HEAD
is to compare HEAD's sha1 to the sha1 of all refs, trying to
find a unique match.
However, some transports actually get to look at HEAD
directly; we should make use of that information when it is
available. Currently, only http remotes support this
feature.

Remote and stale branches are emitted in alphabetical order, but new and
tracked branches are not. So sort the latter to be consistent with the
former. This also lets us use more efficient string_list_has_string()
instead of unsorted_string_list_has_string().
"show <remote>" prunes symrefs, but "show <remote> -n" does not. Fix the

Actually, the comment is wrong; "remote" comes from remote_get(),

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

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.

When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:
bisect_rev=<hash1>|<hash2>
(where <hash1> and <hash2> are hexadecimal sha1 hashes)
and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.
So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:
bisect_rev='<hash1>|<hash2>'
which will be properly evaled later. The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.
A test case is added to the test suite.
And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables
the user may have with these names.

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.

Since it doesn't actually touch its argument, this makes
sense.
However, we still want to return a non-const version (which
requires a cast) so that this:
struct ref *a, *b;
a = find_ref_by_name(b);
works. Unfortunately, you can also silently strip the const
from a variable:
struct ref *a;
const struct ref *b;
a = find_ref_by_name(b);
This is a classic C const problem because there is no way to
say "return the type with the same constness that was passed
to us"; we provide the same semantics as standard library
functions like strchr.

This was mostly being tested implicitly by the "http push"
tests. But making a separate test script means that:
- we will run fetch tests even when http pushing support
is not built
- when there are failures on fetching, they are easier to
see and isolate, as they are not in the middle of push
tests
This script defaults to running the webserver on port 5550,
and puts the original t5540 on port 5540, so that the two
can be run simultaneously without conflict (but both still

In a repository created with git older than f49fb35 (git-init-db: create
"pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is
not created upon initialization. It was Ok because subdirectories are
created as needed inside directories init-db creates, and back then,
packfiles were recent invention.
After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository. This was exacerbated with
8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.
Many packfile related operations in such an old repository can fail
mysteriously because of this.
This commit introduces two helper functions to make things work better.
- odb_mkstemp() is a specialized version of mkstemp() to refactor the
code and teach it to create leading directories as needed;
- odb_pack_keep() refactors the code to create a ".keep" file while
create leading directories as needed.

This patch allows the HTTP tests to run on OS X 10.5. It is not
sufficient to be able to pass in LIB_HTTPD_PATH and
LIB_HTTPD_MODULE_PATH alone, as the apache.conf also needs a couple
tweaks.
These changes are put into an <IfDefine> to keep them Darwin specific,
but this means lib-httpd.sh needs to be modified to pass -DDarwin to
apache when running on Darwin. As long as we're making this change to
lib-httpd.sh, we may as well set LIB_HTTPD_PATH and
LIB_HTTPD_MODULE_PATH to appropriate default values for the platform.
Note that we now pass HTTPD_PARA to apache at shutdown as well.
