Are u really talking console or terminal rather?
Many terminals I know hace a setting for buffer size, sometimes only through config file when no available GUI .

/var/log/portage should contain ebuild log files, possibly colored.

There are patches to recover console scrollback.
Maybe tmux or alike app may be an alternative?

woops
even lead to kernel dev
i mean this kernel patch is a super cool idea
i guess i just need emerge stuff to work like that...kinda not that general need...like kernel stay forever
and i don't know if my memory can handle that pure kernel patch effect
so i think i will try tmux 1st
just wondering how tmux works with gpm

I have color ansi codes included here.
There must be an option...
They are displayed while running | Code: | | gunzip -c /var/log/portage/<category:package-version>.log.gz |
in terminal here.
Color sequences are spoiling emacs output here

Yep kernel patching may be over killing.
Buffer size is hardcoded in kernel.
So big buffer size needs will statically allocate.
rmux should be more flexible in this respect.
Do u use any console test seditor other than nano?

screen remains installed here, but not used anymore since repetitive strange emerge failures when running under screen supervision.
No reason it should be problematic for buffered output.
As far as disk space is concerned, screen is smaller than tmux here: | Code: | user@amd64 ~ $ pckllbin screen
-rwxr-s--x 1 root utmp 482960 déc. 16 14:54 /usr/bin/screen-4.9.1
* app-misc/screen-4.9.1
Total files : 54
Total size : 1.36 MiB
user@amd64 ~ $ pckllbin tmux
-rwxr-xr-x 1 root root 1001736 janv. 27 21:04 /usr/bin/tmux
* app-misc/tmux-3.3a-r1
Total files : 12
Total size : 1.47 MiB |

Sorry,
Just a silly script of mine to show executable files of a given package: | Code: | cat /usr/local/bin/pckllbin
#!/bin/bash
if [[ -z $1 ]];then
echo package name parameter missing
else
equery f $1|grep "bin/"|while read line;do if [[ ! -h $line ]];then ls -la $line;fi;done #excluding symbolic link
equery f $1|grep -v ">"|grep "\.so"|while read line;do if [[ ! -h $line ]];then ls -la $line;fi;done
equery f $1|grep -v ">"|grep "\.pyc"|while read line;do if [[ ! -h $line ]];then ls -la $line;fi;done
equery size $1
fi
|
Currently only showing files within bin/, or like *.so* or like *.pvc.
package name argument can be slotted, or versioned if required.

cool
i seldom take on storage size like that bit
currently i just set 256g for my /dev/sda inside vbox
that's more than enough

hmm....since i don't have an idea for stable lto
that's why i dun take lto options in cflags make.conf
emmm.....do you know of a stable lto flag for high performance?

???stable lto???
gentoo upstream has been chasing away adventurous lto by filtering out on a per package basis.
I do lto build on old system with 4G RAM & PORTAGE_TMPDIR not on ram but disk.
| Code: | emerge -i app-arch/bzip2
...
=================================================================
Package Settings
=================================================================
app-arch/bzip2-1.0.8-r5::gentoo was built with the following:
USE="-static static-libs verify-sig" ABI_X86="-32 (64) (-x32)"
CFLAGS="-march=core2 -mtune=native -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects -pipe -Wa,-mbranches-within-32B-boundaries"
CXXFLAGS="-march=core2 -mtune=native -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects -pipe -Wa,-mbranches-within-32B-boundaries"
LDFLAGS="-Wl,-O1 -Wl,-fuse-ld=bfd" |
Only the 2 lto bits in C*LAGS are required.
Gentoo upstream out filtering only cares about build or runtime failure.
As far as performance or cumbersomeness, user remains on its own.
Setting lto in make.conf shouldn't be an issue nowadays.
Some packages have USE=lto. As such make.conf lto general setting should be cancelled out in /etc.portage/package.env

i also come from the old days......used a week for gnome compile
emmm...do you think lto stuff no matter where i put it.....it give performance rise or not?
if not that much then i would put lto aside

To my poor understanding lto may remove some indirections when possible.
Performance gain should be there, but could be negligible.
I mainly expect disk and ram footprint shrinkage.
-march=native -mtune=native is also another way to reduce footprint.
Performance should increase too.
Downside is that it is not portable to architecture older to current CPU.
-mtune=native would keep faster binaries portable, but bigger too.
If not applied yet, I'd rather favor a -mtune/-march policy over lto which ~ doubles build time.
