kokoko3k / gopreload Goto Github PK

After a recent gopreload update/reinstall I noticed a lot more output in the logs. At first I was confused, because before the update it was rather minimal; only the initial startup messages were there.

I stumbled upon a discussion on the ArchLinux AUR page, where it turns out that there was a bug which caused mapandlock not to restart after the set period. Now with the fixed behaviour, mapandlock is restarting itself as intended and printing all those messages. If I get that right, mapandlock is reloading all those resources again every time in case they were discarded from the cache for some reason?

As it turns out, the previous "buggy" behaviour worked perfectly fine for me. I use gopreload to "preload" my desktop, making the transition between the display manager and the desktop smoother. Because of that I don't really need mapandlock to run every X amount of time.

Would it be possible to add a config option to make it behave like that? As in: run only once and don't keep mapandlock restarting. My current workaround of setting the LONG_DELAY option to something ridiculously high and redirecting the output to /dev/null don't seem like an elegant solution.

I am using artix-dinit and i want brave-browser and telegram-dekstop to preload, so dev can u please make a service for dinit plzz and also include instructions to enable that service :)

Hey there! I noticed this project and figured I'd have some questions as I haven't been able to find answers to them.

1. Does gopreload take into account B. Estahbod preload's functionality?
2. If so, does using gopreload along with preload cause any issues/give any benefits?

I feel like the answers to those questions could be included in the README.

line 119 in main may lead to a buffer overflow if /tmp/listpreload.txt contains a line longer than 511 bytes. The line should be replace by (fgets(line, 512, file)) != NULL. To improve code quality the magic number 512 should probably be a const.

Hi,

A/ I've installed gopreload that way :

Check dependencies : strace, coreutils are already installed

Download source code : $ cd /tmp && git clone https://github.com/kokoko3k/gopreload.git

Compile fmlock & install gopreload :

$ cd gopreload/usr/share/gopreload/fmlock.source/ && ./compile.sh
# mkdir -p /usr/share/gopreload/bin/
# cp /tmp/gopreload/usr/share/gopreload/fmlock.source/fmlock.gopreload /usr/share/gopreload/bin/
# cp /tmp/gopreload/* / -av
# rm  -R /usr/share/gopreload/fmlock.source/

Allow non-admin to run gopreload daemon :
# chown my_username /usr/share/gopreload/enabled /usr/share/gopreload/disabled

Ask GOPreload to prepare preloading for Firefox :
Restart the system, then key :
$ /usr/share/gopreload/bin/Prepare.sh firefox
then press Enter once Firefox is fully launched.
(result on Firefox 46.0.1 : "1264 on 1264 done, will use 135MB to
preload them")

Activate GOPreload
# systemctl enable gopreload

B/ I've checked that GOPreload is working

$ systemctl status gopreload

C/ Compare Firefox cold startup times with and without GOPreload

With GOPreload enabled
Keying '$ time firefox' and manually closing Firefox once it seems to be
fully launched :

real    0m14.235s
user    0m13.708s
sys    0m0.740s

With GOPreload disabled :

real    0m14.289s
user    0m13.656s
sys    0m0.776s

Thanks !
