| Title | MPS doesn't have "incremental step" function for clients |
| Status | closed |
| Priority | essential |
| Assigned user | Nick Barnes |
| Organization | Ravenbrook |
| Description | The MPS has an incremental GC, but it doesn't have any mechanism (other than allocation) for a client to trigger an increment of GC work. This is essential for any sort of opportunistic GC. |
| Analysis | Add mps_bool_t mps_arena_step(mps_arena_t arena, double interval), where the second argument is "how much time, in seconds, is the MPS allowed to take on this step" and the return value is "did the MPS find anything useful to do?" (or, nearly equivalently, "would it be useful to call this function again immediately?"). This shares the mechanism of ArenaPoll() (which is different on the customer branch and in the masters). |
