The RPi4 bots that are runinng the performance tests are slowly filling the /tmp directory and is an issue because after some weeks they run out of disk space in /tmp (which is a ramdisk) and that causes problems. The leftover directories there are the ones that the browser driver uses for creating a temporal home to isolate the browser profile used for the benchmark from the user one # find /tmp/tmph9tcibxt -type d /tmp/tmph9tcibxt /tmp/tmph9tcibxt/.cache /tmp/tmph9tcibxt/.cache/fontconfig /tmp/tmph9tcibxt/.cache/gstreamer-1.0 /tmp/tmph9tcibxt/.cache/MiniBrowser /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17 /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17/Blobs /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17/Records /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17/Records/3ED87E769EF910D7209CCF43EAE3845F7A687C3C /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17/Records/3ED87E769EF910D7209CCF43EAE3845F7A687C3C/Resource /tmp/tmph9tcibxt/.cache/MiniBrowser/WebKitCache/Version 17/Records/3ED87E769EF910D7209CCF43EAE3845F7A687C3C/SubResources /tmp/tmph9tcibxt/.cache/MiniBrowser/HSTS /tmp/tmph9tcibxt/.cache/MiniBrowser/CacheStorage /tmp/tmph9tcibxt/.local /tmp/tmph9tcibxt/.local/share /tmp/tmph9tcibxt/.local/share/MiniBrowser /tmp/tmph9tcibxt/.local/share/MiniBrowser/mediakeys /tmp/tmph9tcibxt/.local/share/MiniBrowser/mediakeys/v1 /tmp/tmph9tcibxt/.local/share/MiniBrowser/storage It seems that the problem is that we are cleaning the temporal directory only if the tests finish correctly, but on timeout or exception we fail to do that
