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. block/curl.c | 553 ++++++++++++++++++++++++++++++++++++----------------------- 1 file changed, 339 insertions(+), 214 deletions(-) -- 1.8.1.4
