Willy Tarreau 656859d478 MEDIUM: session: implement a basic atomic buffer allocator ... This patch introduces session_alloc_recv_buffer(), session_alloc_buffers() and session_release_buffers() whose purpose will be to allocate missing buffers and release unneeded ones around the process_session() and during I/O operations. I/O callbacks only need a single buffer for recv operations and none for send. However we still want to ensure that we don't pick the last buffer. That's what session_alloc_recv_buffer() is for. This allocator is atomic in that it always ensures we can get 2 buffers or fails. Here, if any of the buffers is not ready and cannot be allocated, the operation is cancelled. The purpose is to guarantee that we don't enter into the deadlock where all buffers are allocated by the same size of all sessions. A queue will have to be implemented for failed allocations. For now they're just reported as failures.		2014-12-24 23:47:32 +01:00
