typedef struct HttpRangeContainerBlock HttpRangeContainerBlock |
A structure representing a single range request : either skipping, buffering, or appending As this belongs to a flow, appending data to it is ensured to be thread-safe Only one block per file has the pointer to the container
typedef struct HttpRangeContainerBuffer HttpRangeContainerBuffer |
typedef struct HttpRangeContainerFile HttpRangeContainerFile |
Item in hash table for a file in multiple ranges Thread-safety is ensured with the thread-safe hash table cf THashData The number of use is increased for each flow opening a new HttpRangeContainerBlock until it closes this HttpRangeContainerBlock The design goal is to have concurrency only on opening and closing a range request and have a lock-free data structure belonging to one Flow (see HttpRangeContainerBlock below) for every append in between (we suppose we have many appends per range request)
