There's a memory leak somewhere which I'm trying to detect; it increases by 3MiB on each second, at least on my system [GNU / Linux Debian].
@aristocratos can you explain this excerpt to me, please?
static InputThr& instance() {
// intentional memory leak, to simplify shutdown process
static InputThr* input = new InputThr();
return *input;
}
It's from file btop_input.cpp
if it helps.
valgrind
detected it at line 128 and also
InputThr() : thr(run, this) {
}
from line 88.
Why would we want to intentionally leak memory?
Isn't there any other safer method to accomplish a shutdown process, in a more graceful way?
Please advice.
By the way, the leak takes place immediately with the following command, on my side: make DEBUG=true VERBOSE=true CXXFLAGS=-fsanitize=address,undefined,leak LDFLAGS=-fsanitize=address,undefined,leak ADDFLAGS="-fuse-ld=mold -ggdb3"
.
After it finishes the compilation, I filter for btop
and within info
, I can clearly see the memory leak taking place with every second that passes by; it increases by 3 MiB
steadily.

See #227

Unless you are seeing this with sanitizers off not running in a debugger I would assume the sanitizing and debugger are creating the leak from trying to fix what looks like a leak but really isn't.
But I'm pretty sure this is unrelated to @SeseMueller's reported bug on MacOS arm64.
@SeseMueller What are your hardware specs?
See #227
Got it :+1:

Yeah, it probably is this scenario because indeed I cannot see this behavior otherwise.
@SeseMueller What are your hardware specs?
I've got a Macbook Air M1 with 16 Gb. It might not be related to my specs, but I have no other hardware to test it currently.
I see the same bug / behavior on Ubuntu Server using btop 1.2.3

I have same bug after leaving it on for a long time on macos 12.6 (hw spec: mac m1 pro arm64/16gb ram/1tb ssd nvme). Btop version: 1.2.13 installed with brew package manager.
Same issue here, usually segfaults on startup (though goes accompanied with eg. "terminate called without an active exception", will update once it happens again)

Any update? I suspect this might be just the same issue with #765.
For me the startup of btop
just becomes unreasonably slow, and crashes in a minute. I thought it was macOS breaking something but a clean reboot did not fix it (see uptime below).
That being said, such things did not happen to me until I upgraded to macOS Sonoma 14.4. Could be their aggressive memory-violation strategy uncovering the issue. I'd love to help testing.

Describe the bug
I left a btop terminal window open overnight, trying to reproduce #316, but got a segmentation fault instead.
To Reproduce Start btop. Leave it on for a long time. Come back to a segementation fault.
Expected behavior
It shouldn't segfault

Edit: running it for a third time, I got another error:

So it seems that btop stops working after some time due to some error and displays either:
