compcache swappiness

I am running sparks mod 1.6.4 compcache 32% hack.
I want to change the swappiness to 60.
How would I go about doing this?

Don't do it, it's much too high. I would suggest something around 10-20, i.e. type in terminal:
su
echo 10 > /proc/sys/vm/swappiness
Sent from my Gingerbread on Sapphire using XDA App

Why so low? Just seeking some wisdom.
Thanks.\
Also is this a permanent change or do i have to do this every boot?

This is not a permanent change, you have to apply this every time you reboot your phone. If you want it permanent, you should include it into the /system/bin/compcache script.
Swappiness defines, when data will be put into the swapfile. 100 means, all inactive data can be put into the swap, 0 means, that cached data will be removed first before using the swap. Disadvantage when too much data is within swap: the system speed goes down ... so you have to find a good compromize.

ok so i edited the file and pushed it.
now compcache is not starting and when i type it in the terminal it says permission denied.
Any help?
should i try inputting the command you first gave me into compcache?

After the modification, the compcache file should look something like
...
start)
echo 3 > /proc/sys/vm/drop_caches
modprobe $MODULE
rzscontrol $DEV --disksize_kb=32576 --init
swapon $DEV
echo 10 > /proc/sys/vm/swappiness
;;
...

this is what i have
#!/system/bin/sh
#
# Compcache manager
# [email protected] (cyanogen)
#
DEV=/dev/block/ramzswap0
MODULE=ramzswap
MODULES_DIR=/system/modules/lib/modules/`uname -r`
case "$1" in
start)
echo 3 > /proc/sys/vm/drop_caches
echo 30 > /proc/sys/vm/swappiness
modprobe $MODULE
rzscontrol $DEV --disksize_kb=$2 --init
swapon $DEV
;;
stop)
swapoff $DEV >/dev/null 2>&1
rmmod $MODULE >/dev/null 2>&1
;;
stats)
rzscontrol $DEV --stats
;;
*)
echo "Usage: $0 {start <size>|stop|stats}"
exit 1
esac
exit 0
I cant seem to get it to work.
this is the original too.
it just keeps saying permission denied

You are running the script as root, i.e
> su
# /system/bin/compcache start
to start the script manually?
Before modifing the script, you have to remount /system to set it read-write, otherwise it's read only!

try to fix the permission

I created a script for my rom. But..

Hi to all guys i'm developing a new rom and i'd like to put an executable script in it. I'm not very goot at bash,but you can help me. Here it is:
Code:

It's all ok? Please answer me,in my last three topics nobody answered me.

Uhh, what exactly is the problem?
The only problem I see in this is that you use multiple build.prop files for enabling/disable stagefright and hardware acceleration.
My suggestion is you use sed, a stream editor. This way, you won't need copying files from the folder and may actually make the code easier to read.
This is how I use sed. It creates a backup of the file, searches for the string to be replaced, and then replaces it.
Code:
sed -i.bak 's/ro.media.enc.jpeg.quality=90/ro.media.enc.jpeg.quality=100/g' /system/build.prop
If you plan on doing this, read more about sed. I've kinda forgotten the syntax since I made this 15 days ago and never really used it again. And yes, that's how fast I forget stuff

Thanks kpbotbot ur da man of xda. So,there are no syntax problems in the script except the build.prop? Maybe i can use setprop to disable/enable hwacc/stagefright. I read about setprop in franciscofranco's tweaks topic. Can i use it?

@kpbotbot ..i wanted to look at sed and your example just made it very easy

Lol no I'm not.
I'm not entirely sure how bash handles input. I haven't given scripting much time yet despite the fact that I've been on linux for quite some time xD The logic is in the script though. Have you tested it?
Regarding the franciscofranco's scripts, of course you can use them

I'm trying it with setprop. BTW,i don't wanna piss you off guys but take a look in Optimus One General. Take a look at "APKManager not working" It's very important.

I don't have any idea what in the world is wrong with APKManager since I don't use or plan on using it. What do you need it for anyway?
By the way, had a look at bash scripting. Why does this have 4 read lines?
Code:
read -p "Change boot animation" choice
read -p "Disable/enable Stagefright player" choice
read -p "Enable/disable Hardware acceleration" choice
read -p "Enable/disable Hardware acceleration" choice
read -p "Check Wi-Fi Tx-Power" choice

I've had a quick look on your script. First of all DON'T USE GOTO's!!!
You have two "read -p "Enable/disable Hardware acceleration" choice".
Code:
echo You need to run this only if you have Wi-Fi on!
iwconfig wlan0
Why do you have iwconfig wlan0 lying there? If you don't have Wi-Fi on it will just simply output an error saying it's not on...

Use functions instead.
Try a little tutorial here (http://tldp.org/LDP/abs/html/functions.html) about functions. I didn't recommend using this a few minutes ago for some reason. Anyway, you may need to make a major rewrite to your script, but better readability and flow make it easier to maintain and trace errors.
I'm not sure if there are any other (or better) ways of doing this. Have a look at ruigui's script

I agree, functions would be better than the way you're doing atm.

Yea now i'm gonna take a look at ruigui's script.
Dudes i wanna ask you some:
When i cook my rom and change framework i get bootloop. This doesn't happen if i cook rom w/ original framework,or if i flash a zip that contains that particular framework.
And,i downloaded black mms apk from void and ringnofade. When i put 'em in my rom they force close! Why? Do i need to change classes.dex?
.
EDIT:I taked a look at ruigui's script,but this didn't help me. Please fix my script.
Thanks guys.

I don't know most of bash's syntax, so you do it
Here's how you should do it:
Create the functions. 1 for bootanim changer, 1 for enabling of hardware acceleration, 1 for SF, and 1 for the other one I forgot
Make the choosing part (the one with the reads)
Call appropriate function depending on choice
If you come to think of it this is actually easier than gotos.

Because you're not supposed to replace framework-res.apk because on the first boot, android checks signatures. It will get into a bootloop when it fails on that. (Experts please follow this up. I'm not sure).
Just replace the stuff inside the framework-res.apk with the stuff in the themed framework so as not to break signing. Just open framework-res.apk with an archiving tool and drag stuff onto it replacing the previous stuff. DO NOT EXTRACT
At least that's how I avoid bootloops. Try asking paolo how he did some of the stuff
EDIT: Also, do not resign framework-res.apk. You shouldn't sign it with a testkey xD

We ain't gonna fix your script. If you come here with valuable questions after you did your research, then we can help and answer, if you come here asking for us to fix "your" work, sorry dude, ain't going to happen.
And about gotos, anyone that programmed anything in his/her life will know that gotos = problems and possible security holes.

@ciaox Got bored xD Made a script.
Try to look at mine. The code is straightforward so no need to explain them - http://forum.xda-developers.com/showpost.php?p=12510469&postcount=144
Don't use this as base though. Just look at the functions and how to call them. Then, make yours

Man i'm sorry about dis,i will take a look at kpbotbot's script. Many thanks to everyone. Please keep thread open cuz i'm gonna need you guys..
oh man i get this. I can now call functions,i will let u know
Many thanks
[OT] I wanna integrate dspmanager in my rom but it doesn't work,and if i put libaudioflinger.so from cm7 by mik i can't hear anything. [/OT]

Yeah guys just rewrited my script! Now it must be ok! Check it out,i think it's OK.

you called you hardware acceleration disabler/enabler as "sf" instead of "hw".
I think you should call a case loop instead of this:
Code:
read boot
read sf
read hw
read tx
if test "$boot" == "1"
then boot
fi
if test "$sf" == "2"
then sf
fi. . . . . . .
which should be something like this:
Code:
read $option
case $option in
1)
boot
;;
2)
sf
;;
3)
hw
;;
4)
tx
;;
esac
or something like that. btw, what happens after you're finished with one tweak, let's say disabling/enabling stagefright? I think you should call you main menu as another function and just call it at the bottom of you script. not an expert, just giving some inputs.

Code:
hwon(){
cp /sdcard/openOptimus_resources/Hwacc1/build.prop /system
echo Hardware acceleration enabled.

}
hwoff(){

What happened to setprop? Using multiple build.prop files will make it even more complicated. And if someone made modifications to their build.prop files then used this, they would lose their changes.

Proper executing of sysctl.conf during boot

Edit: For some strange reason it suddenly works after posting this topic.. :') Delete please
Ok so this is the deal, I'm currently working on broodKernel v1.2 (yes not 1.1 but 1.2) and I've noticed that sysctl.conf isn't loaded in any way, I tried loading it with "sysctl -p" and also with su -c "sysctl -p", both tried it in the kernel itself and in init.d scripts, for some reason it doesn't load on boot, but when I load it myself with "su -c "sysctl -p" it works correctly :silly:
mode is: 644, also tried to chown it to system and/or root, both didn't work. then I question myself. is my init.d method correct? Is it running in root mode? I use this:
Code:
service initd /system/bin/logwrapper /system/xbin/busybox run-parts /system/etc/init.d
oneshot
doesn't it need a "user root" at the bottom?, I feel kinda like this emoticon ":silly:" to ask such question, but I really don't know why it's not running correctly, anyhow the sysctl values from the latest thunderbolt seem so unrealistic?:
Code:
vm.dirty_expire_centisecs = 3000
vm.dirty_writeback_centisecs = 500
But ok that's the thunderbolt settings, also I'm not sure if this really improves the system, I've noticed that the first few benchmarks score pretty high but then suddenly the sdcard read/write speed gets screwed by something.
Anyway, here are the scripts (so far):

What replaces stagefright?

I found a script that adds boot audio. In it there is a line calling stagefright, stagefright either doesn't exist on my ROM and I have no clue as to add it.

Not sure if this works , but I will eventually try it , but not now , on my free time.
stagefright indeed is not included , my phone too doesn't have stagefright , if you go to youtube and search for android developement tutorials by "thenewboston" . you'll find 200 videos series , just watch the first 20 ones and you'll learn to use Media which replaces stagefright...I didn't try it yet.
It includes
Our_Player and Media Player and the directory of the song....check it out and give us heads ups!

I appreciate the info, I took a look at his tutorials esp the ones involving animation, he really knows his stuff. I am not a Java programmer by any means and to be honest I find it quite tedious, it's like trying to teach a baby (this case the Dalvik VM) to do basic stuff like draw a green ball took like 20 lines of code!
What I need to know essentially is, do I have to use JAVA to get this to work now? In the past ie ICS and lower, there wasn't a problem with Custom Boot Audio, now with JB it seems it has disappeared from the radar.
I know the binary /system/bin/bootanimation (is this written in JAVA?, is there a source code for this bin?) is called at boot time by init.rc in the following manner:
Code:
service bootanim /system/bin/bootanimation
class main
user graphics
group graphics
disabled
oneshot
/system/bin/bootanimation (at least from what I gather) looks in /system/media for bootanimation.zip (zipped in store mode) decompresses it , looks at desc.txt for the code and displays the animation png by png.
In some desc.txt there is an s line, example:
Code:
# mobility
p 1 0 SOUND
s transdroid.mp3
which is SUPPOSED TO call a custom boot audio from /system/media (.mp3?) at the same time. This appears not to work. So logicaly I think the binary needs some tweaking. Can you offer any suggestions?
As you can see I have spent ALLOT of time mulling over why this,one would think, simple task: display a series of images and play audio at boot time I mean how hard can that be?
I am not trying to be a pest I just need to know WHY this doesn't work in JB (CM10.1)

What's the fastest ROM to date?

Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.

Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.

Up, same question here

I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you

What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
