[Qemu-devel] [PATCH v2 00/11] curl: fix curl read

[Fam Zheng]

CURL library API has changed, the current curl driver is not working.
This patch rewrites the use of API as well as the structure of internal
states. (It is hard to split this to multiple patches as basically all
these changes need to work together.)

BDRVCURLState holds the pointer to curl multi interface (man 3
libcurl-multi), and 4 lists for internal states:
 - CURLState holds state for libcurl connection (man 3 libcurl-easy)
 - CURLSockInfo holds information for libcurl socket interface (man 3
   curl_multi_socket_action).
 - CURLDataCache holds the user data read from libcurl, it is in a list
   ordered by access, the used cache is moved to list head on access, so
   the tail element is freed first. BDRVCURLState.cache_quota is the
   threshold to start freeing cache.
 - CURLAIOCB holds ongoing aio information.

Changes from v1:
   Split to multiple patches. The final status should be identical to v1.

Fam Zheng (11):
  curl: introduce CURLSockInfo to BDRVCURLState.
  curl: change magic number to macro
  curl: change curl_multi_do to curl_fd_handler
  curl: fix curl_open
  curl: add timer to BDRVCURLState
  curl: introduce CURLDataCache
  curl: make use of CURLDataCache.
  curl: use list to store CURLState
  curl: release everything on curl_close
  curl: add cache quota.
  curl: introduce ssl_no_cert runtime option.
