| Title | Emergency collection is not documented |
| Status | open |
| Priority | optional |
| Assigned user | Richard Brooksby |
| Organization | Ravenbrook |
| Description | When the MPS runs out of memory it goes into "emergency" mode, where it will attempt to run a special kind of garbage collection. The documentation does not describe this, or what the consequences might be, or how to control the behaviour, etc. See also job003374. |
| Analysis | Analyse the goals and requirements of emergency collection and its implementation into a design document, for a start. This should help to clarify what users might want from it. |
| How found | unknown |
| Evidence | //info.ravenbrook.com/project/mps/branch/2016-03-12/pause/code/policy.c#4 behaves differently in emergencies. |
| Introduced in | 1.100.0 |
| Test procedure | grep -iIRw emergency manaual/source |
