Bitfields need to specify their signedness explicitly or the compiler is
free to default as it sees fit. With compilers that default 'unsigned'
(SUNWspro 12 seems to do this) the tri-state nature of is_binary
vanishes and all files are treated as binary.

If the the transport helper says it was a forced update, then it is

without the transport-helper knowing about it, namely because some

Turns out that putting 'link:' before the 'http' is actually superfluous
in AsciiDoc, as there's already a predefined macro to handle it.
"http, https, [etc] URLs are rendered using predefined inline macros."
http://www.methods.co.nz/asciidoc/userguide.html#_urls
"Hypertext links to files on the local file system are specified
using the link inline macro."
http://www.methods.co.nz/asciidoc/userguide.html#_linking_to_local_documents
Despite being superfluous, the reference implementation of AsciiDoc
tolerates the extra 'link:' and silently removes it, giving a functioning
link in the generated HTML. However, AsciiDoctor (the Ruby implementation
of AsciiDoc used to render the http://git-scm.com/ site) does /not/ have
this behaviour, and so generates broken links, as can be seen here:
http://git-scm.com/docs/git-cvsimport (links to cvs2git & parsecvs)
http://git-scm.com/docs/git-filter-branch (link to The BFG)
It's worth noting that after this change, the html generated by 'make html'
in the git project is identical, and all links still work.

Currently "git notes add -C $object" will read the raw bytes from $object,
and then copy those bytes into the note object, which is hardcoded to be
of type blob. This means that if the given $object is a non-blob (e.g.
tree or commit), the raw bytes from that object is copied into a blob
object. This is probably not useful, and certainly not what any sane
user would expect. So disallow it, by erroring out if the $object passed
to the -C option is not a blob.
The fix also applies to the -c option (in which the user is prompted to
edit/verify the note contents in a text editor), and also when -c/-C is
passed to "git notes append" (which appends the $object contents to an
existing note object). In both cases, passing a non-blob $object does not
make sense.
Also add a couple of tests demonstrating expected behavior.

When we see a relative config include like:
[include]
path = foo
we make it relative to the containing directory of the file
that contains the snippet. This makes no sense for config
read from a blob, as it is not on the filesystem. Something
like "HEAD:some/path" could have a relative path within the
tree, but:
1. It would not be part of include.path, which explicitly
refers to the filesystem.
2. It would need different parsing rules anyway to
determine that it is a tree path.
The current code just uses the "name" field, which is wrong.
Let's split that into "name" and "path" fields, use the
latter for relative includes, and fill in only the former
for blobs.

If 'src' already ends with a slash, then add_slash() will just return
it, meaning that 'free(src_with_slash)' is actually 'free(src)'. Since
we use 'src' later, this will result in use-after-free.
In fact, this cannot happen because 'src' comes from
internal_copy_pathspec() without the KEEP_TRAILING_SLASH flag, so any
trailing '/' will have been stripped; but static analysis tools are not
clever enough to realise this and so warn that 'src' could be used after
having been free'd. Fix this by checking that 'src_w_slash' is indeed
newly allocated memory.

We currently don't reuse http connections when fetching via
the smart-http protocol. This is bad because the TCP
handshake introduces latency, and especially because SSL
connection setup may be non-trivial.
We can fix it by consistently using curl's "multi"
interface. The reason is rather complicated:
Our http code has two ways of being used: queuing many
"slots" to be fetched in parallel, or fetching a single
request in a blocking manner. The parallel code is built on
curl's "multi" interface. Most of the single-request code
uses http_request, which is built on top of the parallel
code (we just feed it one slot, and wait until it finishes).
However, one could also accomplish the single-request scheme
by avoiding curl's multi interface entirely and just using
curl_easy_perform. This is simpler, and is used by post_rpc
in the smart-http protocol.
It does work to use the same curl handle in both contexts,
as long as it is not at the same time. However, internally
curl may not share all of the cached resources between both
contexts. In particular, a connection formed using the
"multi" code will go into a reuse pool connected to the
"multi" object. Further requests using the "easy" interface
will not be able to reuse that connection.
The smart http protocol does ref discovery via http_request,
which uses the "multi" interface, and then follows up with
the "easy" interface for its rpc calls. As a result, we make
two HTTP connections rather than reusing a single one.
We could teach the ref discovery to use the "easy"
interface. But it is only once we have done this discovery
that we know whether the protocol will be smart or dumb. If
it is dumb, then our further requests, which want to fetch
objects in parallel, will not be able to reuse the same
connection.
Instead, this patch switches post_rpc to build on the
parallel interface, which means that we use it consistently
everywhere. It's a little more complicated to use, but since
we have the infrastructure already, it doesn't add any code;
we can just factor out the relevant bits from http_request.

As refreshing index is not the main task, it makes more sense to make

We do not run the httpd nor git-daemon tests by default, as
they are rather heavyweight and require network access
(albeit over localhost). However, it would be nice if more
pepole ran them, for two reasons:
1. We would get more test coverage on more systems.
2. The point of the test suite is to find regressions. It
is very easy to change some of the underlying code and
break the httpd code without realizing you are even
affecting it. Running the httpd tests helps find these
problems sooner (ideally before the patches even hit
the list).
We still want to leave an "out", though, for people who really do
not want to run them. For that reason, the GIT_TEST_HTTPD and
GIT_TEST_GIT_DAEMON variables are now tri-state booleans
(true/false/auto), so you can say GIT_TEST_HTTPD=false to turn the
tests back off. To support those who want a stable single way to
disable these tests across versions of Git before and after this
change, an empty string explicitly set to these variables is also
taken as "false", so the behaviour changes only for those who:
a. did not express any preference by leaving these variables
unset. They did not test these features before, but now they
do; or
b. did express that they want to test these features by setting
GIT_TEST_FEATURE=false (or any equivalent other ways to tell
"false" to Git, e.g. "0"), which has been a valid but funny way
to say that they do want to test the feature only because we
used to interpret any non-empty string to mean "yes please
test". They no longer test that feature.
In addition, we are forgiving of common setup failures (e.g., you do
not have apache installed, or have an old version) when the
tri-state is "auto" (or unset), but report an error when it is
"true". This makes "auto" a sane default, as we should not cause
failures on setups where the tests cannot run. But it allows people
who use "true" to catch regressions in their system (e.g., they
uninstalled apache, but were expecting their automated test runs to
test git-httpd, and would want to be notified).

Commit a201c20 tried to optimize out a loop like:
for (i = 0; i < len; i++)
data[i] = ntohll(data[i]);
in the big-endian case, because we know that ntohll is a
noop, and we do not need to pay the cost of the loop at all.
However, it mistakenly assumed that __BYTE_ORDER was always
defined, whereas it may not be on systems which do not
define it by default, and where we did not need to define it
to set up the ntohll macro. This includes OS X and Windows.
We could muck with the ordering in compat/bswap.h to make
sure it is defined unconditionally, but it is simpler to
still to just execute the loop unconditionally. That avoids
the application code knowing anything about these magic
macros, and lets it depend only on having ntohll defined.
And since the resulting loop looks like (on a big-endian
system):
for (i = 0; i < len; i++)
data[i] = data[i];
any decent compiler can probably optimize it out.
