Isolate shared HTTP request functionality Move shared HTTP request functionality out of http-fetch and http-push, and replace the two fwrite_buffer/fwrite_buffer_dynamic functions with one fwrite_buffer function that does dynamic buffering. Use slot callbacks to process responses to fetch object transfer requests and push transfer requests, and put all of http-push into an #ifdef check for curl multi support.

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.

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. Signed-off-by: Junio C Hamano <junkio@cox.net>

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.

http-fetch: Abort requests for objects which arrived in packs 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.
