** Description changed: + [ Impact ] + + All the usual issues of memory leaks for long running processes, up to + and including system sluggishness and eventually crashes. + + [ Test Plan ] + + * Using an affected application, e.g. mission-center installed via flat-pak, leave application running for 24 hours and check memory usage + * Enable proposed (https://wiki.ubuntu.com/Testing/EnableProposed) + * sudo apt install -t noble-proposed xdg-dbus-proxy + * sudo reboot + * Run affected application for the same length of time (e.g. 24 hours), observe significantly lower memory usage + + [ Regression Potential ] + + Relatively low. The patch itself is minimal, and is now incorporated in + an upstream (https://github.com/flatpak/xdg-dbus-proxy/pull/58), which + is present in oracular. Please note only the first patch from that PR is + included; the second patch is rather more involved, and it's not clear + that we need it to resolve the issue. + + That said, xdg-dbus-proxy is used by plenty of applications, and it's + very tricky to diagnose whether a memory leak is *actually* fixed, + particularly when not all applications display it, the leak can take a + long time to become particularly noticeable, or the leak is affected by + differing patterns of usage. To guard against this, the test plan + targets an application known to be affected, and requests a particularly + long runtime to make the leak more obvious to detect. + + [ Original Description ] + Reported via IRC and comments on mission-center's GitLab [1]: for users of flatpak installs, xdg-dbus-proxy is leaking memory (causing particular issues for long running processes). The root cause appears to be leaked GVariant references, ultimately fixed in 0.1.6 [2] now available in oracular. However, this still affects the release version on noble, and is likely suitable for SRU. Patch to be prepared...
