[frameworks-kio] [Bug 398908] Dolphin uses up huge amounts of memory over time
https://bugs.kde.org/show_bug.cgi?id=398908 --- Comment #107 from Alexander Meshcheryakov --- Created attachment 145772 --> https://bugs.kde.org/attachment.cgi?id=145772&action=edit Dolphin v 21.12.1 running for half a day, leaked about 1 GiB. I've tried to record heaptrack of running Dolphin v 21.12.1 from Arch linux repos for half a day. Result is in `heaptrack.dolphin.1030819_19.zst`. Dolphin leaked about 1GiB of RAM. I am not quite skilled to analyze this recording. Seems to be caused by numerous KDirWatch and KBookmarkManager invocations. Should I re-record heaptrack on dolphin with debug symbols? Will it yield more useful data? -- You are receiving this mail because: You are watching all bug changes.

Suggests something is wrong near KBookmarkManager or KDirWatch I've recorded another heaptrack ( heaptrack.dolphin.1113185_19.zst ), now for dolphin with debug symbols. It still suggests something is wrong related to KBookmarkManager or KDirWatch. Probably this is partially triggered by my large bookmarks file: $ wc ~/.local/share/user-places.xbel 8297 10501 251857 /home/self/.local/share/user-places.xbel Some entries are related to lots tags I have on my files (like `tags:/python`). Some entries are to long gone sshfs mounts. I probably can figure out something from here. -- You are receiving this mail because: You are watching all bug changes.

It is missing the solid debug symbols it seems, to help further track down the origin of the over memory allocation. The heaptrack trace is great clue to fix this, hope you can make a new one with the solid debug symbols as well. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=398908 --- Comment #113 from Knut Hildebrandt --- Here too, my system also is encrypted. All partitions reside in a LUKS encrypted LVM2 volume. Interestingly, I opened this bug about three months after encrypting my system. No clue if the problem existed before, but I doubt it since I would have reported it earlier ;-) -- You are receiving this mail because: You are watching all bug changes.

To some extent dolphin will always use more memories for each tab and views, since each need an independent KCoreDirLister, that is a cache to read and access the filesystem and enrich the data, and those will use proportionally memory as the directory they access are big. We still have room for optimization for sure. -- You are receiving this mail because: You are watching all bug changes.
