Martin Storsjö 3944ba0cb0 Allow curl to rewind the read buffers
When using multi-pass authentication methods, the curl library may
need to rewind the read buffers (depending on how much already has
been fed to the server) used for providing data to HTTP PUT, POST or
PROPFIND, and in order to allow the library to do so, we need to tell
it how by providing either an ioctl callback or a seek callback.

This patch adds an ioctl callback, which should be usable on older
curl versions (since 7.12.3) than the seek callback (introduced in
curl 7.18.0).

Some HTTP servers (such as Apache) give an 401 error reply immediately
after receiving the headers (so no data has been read from the read
buffers, and thus no rewinding is needed), but other servers (such
as Lighttpd) only replies after the whole request has been sent and
all data has been read from the read buffers, making rewinding necessary.

Junio C Hamano f444e5286e Work around gcc warnings from curl headers
After master.k.org upgrade, I started seeing these warning messages:

    transport.c: In function 'get_refs_via_curl':
    transport.c:458: error: call to '_curl_easy_setopt_err_write_callback' declared with attribute warning: curl_easy_setopt expects a curl_write_callback argument for this option

It appears that the curl header wants to enforce the function signature
for callback function given to curl_easy_setopt() to be compatible with
that of (*curl_write_callback) or fwrite.  This patch seems to work the
issue around.

Daniel Barkalow c13b2633f4 Make walker.fetch_ref() take a struct ref.
This simplifies a few things, makes a few things slightly more
complicated, but, more importantly, allows that, when struct ref can
represent a symref, http_fetch_ref() can return one.

Incidentally makes the string that http_fetch_ref() gets include "refs/"
(if appropriate), because that's how the name field of struct ref works.
As far as I can tell, the usage in walker:interpret_target() wouldn't have
worked previously, if it ever would have been used, which it wouldn't
(since the fetch process uses the hash instead of the name of the ref
there).

Mike Hommey 9fc6440d78 Set proxy override with http_init()
In transport.c, proxy setting (the one from the remote conf) was set through
curl_easy_setopt() call, while http.c already does the same with the
http.proxy setting. We now just use this infrastructure instead, and make
http_init() now take the struct remote as argument so that it can take the
http_proxy setting from there, and any other property that would be added
later.

At the same time, we make get_http_walker() take a struct remote argument
too, and pass it to http_init(), which makes remote defined proxy be used
for more than get_refs_via_curl().

We leave out http-fetch and http-push, which don't use remotes for the
moment, purposefully.

Daniel Barkalow fc57b6aaa5 Make function to refill http queue a callback
This eliminates the last function provided by the code using http.h as
a global symbol, so it should be possible to have multiple programs
using http.h in the same executable, and it also adds an argument to
that callback, so that info can be passed into the callback without
being global.

Alexandre Julliard 9cf04301b1 http-fetch: Disable use of curl multi support for libcurl < 7.16.
curl_multi_remove_handle() is broken in libcurl < 7.16, in that it
doesn't correctly update the active handles count when a request is
aborted. This causes the transfer to hang forever waiting for the
handle count to become less than the number of active requests.

Junio C Hamano 500ebb0196 Work around http-fetch built with cURL 7.16.0
It appears that curl_easy_duphandle() from libcurl 7.16.0
returns a curl session handle which fails GOOD_MULTI_HANDLE()
check in curl_multi_add_handle().  This causes fetch_ref() to
fail because start_active_slot() cannot start the request.

For now, check for 7.16.0 to work this issue around.

Art Haas c774b2dcf6 Patch for http-fetch.c and older curl releases
Older curl releases do not define CURLE_HTTP_RETURNED_ERROR, they
use CURLE_HTTP_NOT_FOUND instead. Newer curl releases keep the
CURLE_HTTP_NOT_FOUND definition but using a -DCURL_NO_OLDIES
preprocessor flag the old name will not be present in the 'curl.h'
header.

This patch makes our code written for newer releases of the curl
library but allow compiling against an older curl (older than
0x070a03) by defining the missing CURLE_HTTP_RETURNED_ERROR as a
synonym for CURLE_HTTP_NOT_FOUND.

In fetch_object, there's a call to release an object request if the
object mysteriously arrived, say in a pack.  Unfortunately, the fetch
attempt for this object might already be in progress, and we'll leak the
descriptor.  Instead, try to tidy away the request.
