#3571: torrents get lost
----------------------------+------------------------
Reporter: Xuefer | Type: bug
Status: new | Priority: critical
Milestone: needs verified | Component: libtorrent
Version: 2.1.0 | Keywords:
----------------------------+------------------------
steps to reproduce:
1. make sure there're more than 128 torrents added, in any state
2. use ltconfig plugin to set alert_queue_size to 100 (or load preset:
minimal memory usage, which use 100 for alert_queue_size)
3. restart deluge

only about 126~130 torrents get loaded. restart deluge again you'll see
size of torrents.state get slim down to a few kbytes from mbytes
"Finished loading 427 torrents in 0:00:06.760026" is not appearing in the
log. unless the count is slim down

alert_queue_size = 100 is not required for this to happen

Reason: loading existing torrents, rely on alert_queue as callback
Suggestion: need a reliable callback mechanic other than alert_queue which
is limited by size.

Comment (by Cas):

Yes Deluge has a queue size default of 10000 since the queue is critical
to functionality so not unexpected that a very low value would cause
issues

> Alerts is the main mechanism for libtorrent to report errors and events.

Deluge requires the queue for events but there are potential improvements
to alert handling.
