gcc-10.3.0 has just been released.

Pat was speaking of this yesterday in slackware's what's new. I'm expecting an update soonish an then a beta of slackware 15.0. The release is approaching. :)

Hey Alan!

gcc-10.3.0 has just been released.

Pat was speaking of this yesterday in slackware's what's new.
I'm expecting an update soonish an then a beta of slackware 15.0.

I am calling it 15.0-ish. I have it installed on a laptop and it works rather well but I haven't really done much with it. No fidonet on there ... yet. My wireless networks work good though and am working on a 5GHz host which is where the laptop will connect to as it's default connection. So far so good.

I plan to start a new build of x86_64-motorshed-linux-gnu very soon. My last attempt with building a toolchain using the release candidate failed on coreutils which is a mission critical package. I'll know shortly if the problem still exists and may have to hold off on an install until I discover a fix.

Life is good,
Maurice

i like to learn more on how to disabled compressed memory

symtoms is when doing

swapoff -a

then in top there is still threads that show it have or still have usage on swap memory, is it sign of memory leak ?

Hey Benny!

I see it is now in Slackware-15.0-ish.

Compression is evil. I would definetly get rid of that.

swapoff -a

I haven't used swap in around 25 years now. What for? DDR4 is cheap, or at least was the last time I checked and infinetly better than swap. Why would you do this to any machine?

is it sign of memory leak ?

I don't know. All I know is that real memory seems to be working fine and thus no need for swap to act as drag on any system.

Wait a minute! Yes I have used swap lately on a raspi but that was only because it lacked real memory and I needed more to enable 64-bit gcc and friends (aarch64-unknown-linux-gnu). However that fell by the wayside once I was successful getting it to work. Pure 64-bit too. A real shame that turned out to be although I did learn much from the experience, the biggest lesson being raspi's require more real memory. 8G would have been nice. Oh well ... live and learn eh?

Maurice

On a busy server a little bit of swap can be usefull, so the kernel doesn't start killing random processes right away when it runs out of real memory. This gives the administrator some time to take messures, without risking unplanned interrupted services...

Hey Wilfred!

kernel doesn't start killing random processes right away when
it runs out of real memory.

After +20 some odd years I have yet to see that happen.

The one instance where swap was needed was on the raspi when attempting to update to aarch64-unknown-linux-gnu and once that was done I turned off swap and then later eliminated it from the microSD card once I was satisfied it wasn't needed anymore. Swap on SD cards isn't a good idea to say the least but I was willing to sacrifice one for the cause.

The card still works but I only use it for storage these days as I retired the raspi once I was satisfied I did all I could for that cause and that other than a learning experience there is nothing there of any real value to me personally, especially the crippled onboard wireless chip. What a waste.

Life is good,
Maurice

As memory leaks are usually bugs, there is nothing I can specifically recommend here. I can only say that I experience this kind of issue every once in a while, and without swap a system can run out of memory pretty quickly. Sometimes the kernel will start terminating processes at random before you can even think CTRL-C.

Hey Gerrit!

As memory leaks are usually bugs, there is nothing I can
specifically recommend here.

Just as well since I probably avoid running whatever it is anyhow. So far everything has been behaving itself and there is definetly more than enough ram, overkill I'd say.

I can only say that I experience this kind of issue every once
in a while, and without swap a system can run out of memory
pretty quickly.

Understood. However the two mini-servers currently being used here only have an SSD which apparently is an issue for swap. For any serious file storage I have a server on the private LAN that takes care of regular sata drives as it can hotswap them if and when it matters. I suppose if push comes to shove I could supply swap over the network but offhand I don't like this idea.

Sometimes the kernel will start terminating processes at random
before you can even think CTRL-C.

No keyboard(s) on them. Occasionaly a monitor to watch a new system boot up but that doesn't happen too often.

On the one I am writing this reply on, I am using a ssh login from my main workstation which is also on the private LAN. Both the Brain and the EuroPoint are running on wireless hotspots but there is no access from the wireless interface. That is just for the neighbours who need them to access the internet with their smart devices, mostly smartphones. So far the lack of swap hasn't been a concern and probably has saved money given my frugal nature of doing writes to their SSDs. +20 years ago it was a bootable CompactFlash that kickstarted this whole idea for me. That was around 1999-ish. No swap then either.

Maurice

I'd like to lol a little bit. ;-) The raspi is designed as a cheap learning plattform for everyone. Your lession learned was that swap can be useful. The next lesson would be that it's better to avoid swap for performance but this one you knew already. People new to IT would learn that the hardware resources need to match the task(s). Fullfilled its task the raspi had.

Always leave some swap on a Linux system even if you have 32, 64GB, or
even a TB of memory. I've seen applications completely consume all
available memory and, thankfully memory was monitored, was able to kill
the processes that consumed all the memory to prevent the server from
going down. Ultimately, it's a safety net, it is stupid not to use it.

This is similar to partitioning out the file systems on a Linux
server. Keeping everything in one file system will bite you in the butt
if you have a directory fill up.
