Package: nyx
Version: 2.1.0-2.1
Severity: normal
nyx leaks memory, 262144 (== 64*4096) bytes every 5 seconds in my case.
Under Buster it didn't.
Running
strace -e trace=mmap -v -ttt -f -p $(pgrep nyx)
shows calls to
99483: mmap(NULL, 262144, ...)
every 5 seconds. Running
dd if=/proc/$(pgrep nyx)/task/99483/mem bs=4096 count=64
skip=$((0x7f37bfe80000/4096))|xxd
tells me it's the information from the Connection window. Running
(which needs 6cd89c4[1] applied first):
nyx --debug /tmp/nyx.debug
reveals that nyx queries the circuit information ("GETINFO
circuit-status") into a variable LAST_RETRIEVED_CIRCUITS every 5
seconds in
/usr/lib/python3/dist-packages/nyx/panel/connection.py:_update
I suspect something prevents the allocated data from being GCed.
N.B.: I also tested with onioncircuits to see if the bug might be in
stem, but it showed no sign of leaking.
