[TUTORIAL] How to test if scripts (tweaks) actually work

---

Hello!

As some of you know, pvyParts and I have been working on a custom stock-based ROM, T.E.A.M., which was initially released as a themed ROM to offer transparency and replace the Theme Chooser that we haven't been able to port properly, giving endless options on custom backgrounds (since your wallpaper is the system background).

As the ROM evolved and custom kernels became available, I wanted to tweak it using init.d scripts.
As all good developers here do, I searched the Android Software and Hacking General section,
browsed other devices' forums and came up with some tweaks that were really good -on paper.

To my disappointment, most of these did not work.
And I am not saying this because I didn't "feel" a difference
or because I could not spread my X10's smoothness on a cracker.

There is actually a way to test if a script runs with no errors, a.k.a actually works.

Without further adieu, here is how:

1. Place the script you want to test (let's say test.sh)
in /system and give it all permissions,
either with Root Explorer or via adb:

adb shell chmod 777 /system/test.sh

NOTE: Sometimes scripts don't have an extension (sh).
It's OK, you can still test it with this method.

2. Now install an app like Script Manager and run the script.
Or, do it via adb:

adb shell sh /system/test.sh

3. Now there are 3 things you might face:

- If you get an error in return, it means the script doesn't work,
so no point in placing it in init.d and running it at every boot, right?

- Some scripts include debug, so you may get a message saying Done, Success, or whatever, which means you are good to go.

- You might not get any output at all, but still that means the script ran fine.

For the latter two cases, you can safely run the script at boot by placing it in init.d folder.


The reason this thread is in development, is because I feel that since the X10 is getting old and many developers have left,
(but luckily new ones still appear, which is plainly AWESOME ), quality of ROMs is very important.
We have fewer choices, so let's make them worthwhile!

Doing it right now.

Let us know how it went!

its good to see dev sharing their dev knowledge and skills. this will make more dev for x10. more dev, more improvement we can do on our phone. Thanks My Immortal / iridaki. you're awsome

Thank
cause script stress me well
Now i can see if work or not


X10-tripmiui,iris,00

so if my rom has a init.d folder, does it means it supports or run script (on init.d folder) at boot? is there a way to check if my rom has init.d support??

Yes, support at boot.
To my less knowledge, just look if there is a init. d folder in system/etc/
When you make an own rom check if the kernel you wanna use,has init. d support.
Hope I didn't talk crap and this is right


Sent from my X10i using Tapatalk

but im really confuse here, i found this script,

/etc/init.d/03sdcardspeedfix

at some line of this script, it reads;

READ_AHEAD_KB="2048"

i know some c++ programming, and from what i know the value 2048 is assigned to read_ahead_kb, so i assume its the same in android. BUT, after reboot, i jumped to

/sys/devices/virtual/bdi/179:0/read_ahead_kb

to found out that its still 128, then i started thinking that the script didnt run, but the dev says the rom is init.d supported.

is there a way to test if init.d is reallty working? like at terminal emulator?

sure man !

you have two way for run tweak

in install-recovery.sh

or ini.d folder

but for be sure

create a file in system/etc

name it "install-recovery.sh"

copy this in and give all permission.



#!/system/bin/sh

#Mount Points
busybox mount -o remount,rw,noatime,nodiratime / -t rootfs
busybox mount -o remount,rw,noatime,nodiratime /sys -t sysfs
busybox mount -o remount,rw,noatime,nodiratime /system
busybox mount -o remount,rw,noatime,nodiratime /data
busybox mount -o remount,rw,noatime,nodiratime /cache


#init.d support
busybox run-parts /system/etc/init.d

run-parts /system/etc/init.d >> /data/local/tmp/runparts.log 2>&1







now put your tweak in ini.d folder and reboot


be carefull !
if you have zipalign tweak
this tweak kill all tweak at boot because it unmount partition
and make it r/o instead of r/w

well,
tweak cannot access system or data like VM or sdcard tweak like read-ahead kb 2048.


now go in data/local/tmp
and check the log
to see if all it ok


but if ini.d does not run,
you could
insert tweak in install-recovery.sh

like this



#!/system/bin/sh

#give system permissions
busybox mount -o remount,rw /system
chmod 777 /system

#init.d support
busybox run-parts /system/etc/init.d

run-parts /system/etc/init.d >> /data/local/tmp/runparts.log 2>&1
