Bug ID: 161168
Summary: WebDav UCP - has (fairly) busy-loop in a thread
refreshing locks
Product: LibreOffice
Version: 24.8.0.0 alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: framework
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: michael.me...@collabora.com
It appears that:
ucb/source/ucp/webdav-curl/SerfLockStore.cxx
Hasa thread that wakes up 25 times per second:
std::this_thread::sleep_for( std::chrono::milliseconds(1000/25) );
to see if some timeouts have expired.
However - the method 'refreshLocks' could easily tell us how long it will be
until we need to refresh another lock; and if we wait/sleep on a condition we
can signal that if new ones are added.
This would make scheduling far more relaxed.
Suggest adding a shortest deadline in milliseconds to wake up again as a return
value from 'refreshLocks()' there and sleeping that long.
