* | Fix some looping_call calls which were broken in #3604 | Richard van der Hoff | 2018-07-26 | 1 | -2/+8 |
| | | | | | | | | | It turns out that looping_call does check the deferred returned by its callback, and (at least in the case of client_ips), we were relying on this, and I broke it in #3604. Update run_as_background_process to return the deferred, and make sure we return it to clock.looping_call. | ||||
* | Resource tracking for background processes | Richard van der Hoff | 2018-07-18 | 1 | -0/+179 |
| | | | | | | | | | | | | | | | | This introduces a mechanism for tracking resource usage by background processes, along with an example of how it will be used. This will help address #3518, but more importantly will give us better insights into things which are happening but not being shown up by the request metrics. We *could* do this with Measure blocks, but: - I think having them pulled out as a completely separate metric class will make it easier to distinguish top-level processes from those which are nested. - I want to be able to report on in-flight background processes, and I don't think we want to do this for *all* Measure blocks. | ||||

| | | | | | | | | PyPy's incminimark GC can't be triggered manually. From what I observed there are no obvious issues with just letting it run normally. And unlike CPython, it actually returns unused RAM to the system. Signed-off-by: Vincent Breitmoser <look@my.amazin.horse> | ||||
