auto-launch scripts

Ok, searched and couldn't find, so if you know a thread where this is touched upon, please link to the post?
I'm trying to disable a2sd on JAC's latest rom (compcache just makes it so much more livable) and enable linux swap and compcache. what I ended up doing was modifying the a2sd script so that it checks for a third partition instead of a second, that way, I can disable a2sd by not having a third partition. I also changed the swap script to check for a second partition. I'm pretty much making a2sd optional in order to use compcache (since it's the a2sd script that launches the userinit.sh script at /system/sd, if there's no ext partition, it jumps to else and ignores the part to run userinit.sh). Anyway, I'm wondering how it is that a2sd is being launched on startup, and wether it's being launched on every single boot or just on first boot. I'm wondering because i want to replace it with my own script, now, i could either copy the contents of my script to a2sd script, or i could find out how it is that scripts are auto-launched on android so that i can add them later instead of just appending everything to the a2sd script and hoping it works (since some things will conflict).
Here's my modified script, anyway, if anybody is interested in running compcache and swap without a2sd, only need two partitions, fat32 and linux-swap, if you add a third ext2 partition, then you enable a2sd (data, dalvik-cache, and data-private, I like leaving app_s internal for speed):
notice, this is not MY script per se, just modified from jac's a2sd and the userinit.sh for cyanogen's compcache roms

[PATCH][A2SD]MT3G Friendly a2sd Patch - Firerat

EDIT: 2010-05-13
a note on this modded a2sd and CM5
This mod is *not* required , cm5 has a newer/better way of implementing a2sd
but it will do no harm, it just simply won't do anything
Firerat Patch - a2sd for MT3G users
NOTE My Modified a2sd is intended for both G1s and MT3Gs, one a2sd suits both MT3G's and G1s
Ok, I thought it was about time I gave a full explanation on my mt3g-a2sd patch
why MT3G users should not use an ext partition
why MT3G users who have just 2 Parttions ( FAT / SWAP ) get failed boots
How my modifications reslove this situation
Why should MT3G users not use an ext partition?
the answer is quite simple really, they don't need it.
a2sd was designed with G1s in mind, the G1's /data partition has a limited amount of space available, just over 74mb or 89mb with 'DangerSPL' whereas the MT3G has just over 295mb around 3 or 4 times the G1's.
Although I have not 'benchmarked' the 'speeds' of internal vs sdcard , I belive it is widely accepted that the internal memory is significantly faster than sdcards, and therefore if an MT3G can use it, it should.
So I hope we are all now agree that the MT3G's internal memory should be used for apps/dalvik-cache
Why do MT3G users who have just 2 Parttions ( FAT / SWAP ) get failed boots?
the problem is within the a2sd script, here is a section of the code, with my annotations in blue
Code:
[COLOR="Blue"]Here the script checks for second partition[/COLOR]
if [ -e /dev/block/mmcblk0p2 ];
then
[COLOR="Blue"]it exists so it does a fsck on it [/COLOR]
# fsck the sdcard filesystem first
e2fsck -fy /dev/block/mmcblk0p2;
# set property with exit code in case an error occurs
setprop cm.e2fsck.errors $?;
[COLOR="Blue"] an error is returned ( it is swap not an extfs ) error no. is just stored, no action [/COLOR]
# mount and set permsd
busybox mount -o noatime,nodiratime -t auto /dev/block/mmcblk0p2 /system/sd;
[COLOR="Blue"] The above mount command fails, it is swap
<snip some link clean ups>[/COLOR]
# move apps and dalvik cache from internal memory to sdcard
for i in app app_s app-private dalvik-cache;
do
[COLOR="Blue"] here directories are normally created on sdcard
but as sdcard isn't mounted it tries to put them on the /system partition,
since /system is mounted read only , it fails[/COLOR]
if [ ! -d /system/sd/$i ];
then
mkdir /system/sd/$i;
fi
busybox chown 1000:1000 /system/sd/$i;
busybox chmod 771 /system/sd/$i
if [ -d /data/$i ] && [ ! -h /data/$i ];
then
[COLOR="Blue"] the next line tries to copy files from internal memory to /system/sd,
which is read only, it fails[/COLOR]
busybox cp -a /data/$i/* /system/sd/$i/;
busybox rm -f /data/$i/*;
[COLOR="Blue"] BANG , that line above just deleted all your apps,
your system will not boot[/COLOR]
fi;
done;
# symlink app dirs - they must be on the same filesystem
for i in app app_s app-private;
do
if [ -d /data/$i ] && [ ! -h /data/$i ];
then
busybox rm -rf /data/$i;
[COLOR="Blue"] its just removing empty directories,
and creating a link to none existent directories in /system/sd/[/COLOR]
busybox ln -s /system/sd/$i /data/$i;
fi;
done;
How my modifications reslove this situation
Quite simply by skipping the above code, with this.
Code:
# check if not a G1 ( assuming mt3g ) - Firerat 2010-03-23
rohardware=`getprop ro.hardware`
if [ "$rohardware" != "trout" ];
then
FindSwap
ReturnAppsToData
$SETPROP_CMD cm.filesystem.ready 1;
exit 0;
the != is not equal to, getprop ro.hardware will return sapphire, not trout,
so this code will run my findswap, and ReturnAppsToData Functions
you can find the ReturnAppsToData Function in my next post
Code:
FindSwap ()
{
if [ "`sed -n '$=' /proc/swaps`" -gt "1" ];
then
echo "Swap appears to be already setup, skipping checks"
return
else
for isitswap in `ls /dev/block/mmcblk0p*` ; do
swapon $isitswap 2>/dev/null
if [ "$?" = "0" ];
then
busybox mount -o rw,remount /system
sed s~/dev/block/mmcblk0p.~$isitswap~ /system/bin/user.conf -i
busybox mount -o ro,remount /system
break
else
echo "$isitswap is not swap"
fi
done
fi
return
}

the Flash update in the OP should convert an MT3G emulating a G1 with broken keyboard back into an MT3G with a spare ext partition, for a chroot linux or something, or just fix it up before messing about re-partitioning
but I have to say, I have not tested the apps back to data part, it should check if there is room, it did cross my mind that some may have hundreds of apps and it they would be too big to fit, so I try to check

Lovely, thanks! I'm going to try this now, as I'm just re-flashing King's Legend2g1

Would this be able to run properly once a ROM is already established? Like a ROM I've had for a couple days? Or would this need to be flashed on a ROM that's recently installed. For instance:
Code:
Flash ROM
Flash a2sd
reboot

yes, my latest will copy app, app_s, app-private and dalvik-cache from the ext partition to /data
( unless it finds that they are all too big, in which case you are still g1 with broken keyboard but your gota have *a lot* of apps before that happens )
But as I only have a G1 I have not been able to test it properly, but the logic is straight forward so fingers crossed I have not missed a typo...

Hmm. I'm having a problem with it. Well, maybe with it. So the first time I wiped, repartitioned with just a swap (190mb) and the rest as fat32. I flashed Rom, then flashed your patch, then flashed the vega kernal patch. Booted up, it all worked, past the HTC quietly brilliant screen, but then sat there on the black HTC bit. If I let the screen sleep, it looked like Sense had loaded, but when I unlocked it it was still sitting there on the black HTC screen with Clock repeatedly FC'ing. So I wiped, reflashed this time just the Rom and the Patch and this time it's getting to the setup screen. It was working fine. I connected to wifi, then signed into my google account (still on the setup) and then onto the next screen about google using my location, and then Settings FC'd. Since then I've been in a loop of going back to the start of the Setup menu, never getting further than the language screen again. I will reboot and see if that helps. Failing that, I'll re-flash with JUST the rom, and see if it sets up ok. If so, I suppose I won't need the patch afterall!
I'll keep you updated.

I flashed it as I was typing, just outta curiosity, and its seeming to work properly. Good work sir!

Thanks!! I'll try it out on superD and tell you how it goes

Further to this, I rebooted and let it sit for a while, then tried again. I got as far as the Facebook sync bit on the Setup but no dice, FC settings and back to the start. So I wiped and re-flashed just the rom, which has now been sitting on the HTC Quietly Brilliant screen for about 15 minutes. The only option I haven't tried yet is installing Legend2g1 + the Vega patch, booting and seeing if it works.

try one of my Legend for NoneDangerSPLs
link in my sig
they are using an MT3G friendly a2sd out of the box, but without the apps back to data part

Firerat! This is AWESOME!!!!! I've needed this for a while, but my experience of bash scripting is less than mediocre.
I have 3 questions:
1) To make this usable on g1, I can just remove the ro.getprop section, correct? or do I need to change it instead of removing it?
2) To guess whether or not my /data folder will even fit on the g1, can I simply extract the zip and look at the file size of "data" folder inside, or is there something more? and if that barely fits, will dalvik-cache still go on sd?
3) If I am installing a bunch of apps and it fills up /data (assuming I am using this script), then will the "move apps and dalvik-cache to sd" option in amon_ra work?
Thanks man!

Out of the box it will work with G1s and MT3Gs, that's the idea One Script two phones.

with a G1 I let everything go to sd,
but if I work out that dalvik-cache will fit on data , leaving 10mb free I keep it on data
I do need to tweak it a little, the Legend Cache Hacks I have done need a reboot to push dalvik-cache to sd
And , in future ( providing DEVs adopt it ) all system apps can go to system
check my Eris / Legend on NoneDangerSPL in sig for more info
I can recommend the ErisCacheHack, and Legend for NoneDanger
( DangerLegend is still wip, but I'm hoping my latest works )

yeah, it should do, the a2sd will move the dalvik-cache back if it thinks there is enough space, but at the moment it won't touch the apps
I am going to develop the a2sd a little more, and get it to auto move apps between data/sd depending on size
I kind of hint at that in the comments in the last function
but one of my goals is to get unionfs going, having some apps on internal and some on SD
it will also make the cache hack much easier
I'd just flash a linux base, the android being a tarball, and extract the android on first boot into a unionfs, if I'm right, the files will automagicaly go to where space is available
failing that, I have other ideas

If working unionfs for a2sd search XDA (in particular, this forum) first. It's been done but was found wanting from a performance standpoint--you may as well build on that experience. You might also see if you get better results from aufs.

Thanks for the quick response. In regard to #1, if I wanted to make the script do what it usually does on mt3g happen on my g1, can I simply remove those lines?
Also, I'm testing the legend patch right now ON DANGER, but fyi the 4shared links for the prepatched rom don't work... that's why I did it myself. flashing.

hmm.. Ill flash this over the current rom im using i guess and ill see how it goes. using that SuperEclair 2.3. should i wipe before flashing or its unnecessary?

this isn't something you flash, it's something you stick into /system/bin when you're cooking a rom... as far as I know...

[Script] Chroot Control Script

One of the fun things you can do on your Android device, is to play around with different ways of getting a real distro (Debian, Ubuntu etc.) working along side the Android system. There are several (A lot) of tutorials in here on how to do this, so this part will not be covered here. This thread only contains some scripts that will help make it easier working with the chroot.
Most of the scripts that comes with the endless pool of chroot tutorials, is only made to mount and unmount the distro image in the most simple way. But nothing that helps walking in and out of the chroot without mount/unmount, and nothing that takes different services, busy devices etc. into consideration.
The debian.sh script in this thread has many tasks. It will on execution check to see if the image is mounted or not. If the image is mounted, it will just enter the chroot. If not, it will mount the image and then enter the chroot. On exit it will provide you with the option of exiting the chroot or exit and unmount.
Also it provides 4 custom scripts that is placed and executed inside the chroot. One for mount, unmount, enter chroot, leave chroot. This makes it possible to control chroot services much easier.
The script debian.sh is executed using the command "debian". You can also unmount the chroot from within the android shell by executing "debian unmount" instead of entering the chroot and then exit choosing to unmount.
The unmount process has several and different unmount attempts in case of busy devices, running services etc. which will make sure that the chroot is successfully unmounted.

By default debian.sh will look for /mnt/sdcard/debian.img and mount it at /data/debian
The script has build-in first-time-install functionality that will create missing directories etc. Just change the variable "FILESYSTEM" in debian.sh to the correct path and filename of your distro image, and it will handle the rest.
Chroot Init Scripts
Inside your chroot, you can create the directory /etc/init.chroot and create the fallowing files.
rc_mount.sh - Executed after mount
rc_unmount.sh - Executed before unmount
rc_enter.sh - Executed when entering chroot
rc_leave.sh - Executed when leaving chroot
Here are an example of a mount and unmount script used to control tightvncserver.
File: (chroot) /etc/init.chroot/rc_mount.sh
Code:
#!/bin/sh
# Make sure that the vncserver is completly stopped before starting.
if [ ! -f /tmp/.X11-unix/X1 ] && [ ! -f /tmp/.X1-lock ]; then
# Start vncserver
vncserver -geometry 800x480 :1
else
# This is in case something went wrong the last time
# it was shut down. Perhaps an uncomplete unmount.
vncserver -kill :1 2> /dev/zero
unset /tmp/.X11-unix/X1 2> /dev/zero 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero 2> /dev/zero
vncserver -geometry 800x480 :1
fi
File: (chroot) /etc/init.chroot/rc_unmount.sh
Code:
#!/bin/sh
# Only stop this if it is started
if [ -f /tmp/.X11-unix/X1 ] || [ -f /tmp/.X1-lock ]; then
vncserver -kill :1
# Make sure that these are removed
unset /tmp/.X11-unix/X1 2> /dev/zero
unset /tmp/.X1-lock 2> /dev/zero
fi
Using these scripts, the VNC Server is started on chroot mount and stopped on chroot unmount. You can still leave and enter the chroot keeping the VNC Server running.

[Q] SD-EXT script for Android 4.2.2?

Hi is there a script that increases internal storage via sd-ext for Cyanogenmod 10.1 (android 4.2.2)?
If so could someone link it to me?

Mounts2SD worked really well for me on 4.2.2; it's my a2sd script of choice. Here's the XDA thread about it.

I was using link2sd with King Evo ROM but not if I'm so result. Nor well but if I use function works.
If someone recommended I would appreciate any Script

Create a file name 40int2ext then paste this.
Open notepad or notepad++.
Save file as 40int2ext
delete .txt extension at filename. (note you should set your pc to show extension file names)
You must have an ext partition at your sd card. I use ext4. You could choose among ext2/3/4 though.
As cronmod suggest the maximum size for partition must be 1GB/100mb of internal storage. I used about 512mb

PROBLEM!
I wanted to extend my EXT partition size. So for that, I used Mini Partition Tool Home Edition to unallocate everything and create the full partition as primary sd card. Then i rebooted into recovery (CWM) and partitioned my sd card and created ext partition of 512 mb. But now, I am unable to use that ext partition. I cant mount it, even in recovery! SD card is working fine but problem is EXT. I have tried it with TWRP too and tried to create a SWAP too. But no luck!
What to do now?
pls dont tell to buy a new SD card.

Then i rebooted into recovery (CWM) and partitioned my sd card and created ext partition of 512 mb. But now, I am unable to use that ext partition. I cant mount it, even in recovery! SD card is working fine but problem is EXT. I have tried it with TWRP too and tried to create a SWAP too. But no luck!
What to do now?
pls dont tell to buy a new SD card.

You can't use the ext partition like the primary partition. It's either a script use it like link2sd,data2sd,ext2sd or anythingyoucanimagine2sd.
Try this method. After you partition your sdcard. and installed cronmod's int2ext. Try to reaplce the 40int2ext file with the one I provide. I also suggest to remove other scripts currently at the /system/etc/init.d folder but retain the two 00banner and 90userinit. You can use any root file browsers. Then restart your phone

Thats fine. I have been using it before too.
But now i am unable to mount sd-ext, even through recovery! No use of scripts. They wont work and some of them may even make my phone go to bootloop.
I wanna know how do i partition it now. Some other method than CWM or TWRP.

Merging data and sdcard partition

I hate to have my 8 gigs of internal storage splitted between data and sdcard, considering that I have a 16gigs external sd, this is a lot annoying. So, checking the partition tree I found out that it should be possibile to merge internal_sd and data partition.
Now, this operation is risky, so I would like to ask if someone (even on other devices) has tryed this and succeded, or any possibile side effects on system behavior.
thanks

any news for this mod?

I'm interested in this too, I want to get my Google Play music off my internal fake "sdcard" mount and onto my actual SD card. Plus I'm tired of running out of space on my "internal storage" and having to move it to the (also internal) "phone storage"...
I've had a look around the forums and there seems to be a few posts on achieving this for other handsets (Samsung Galaxy Ace, HTC One X) but I don't know how applicable the advice on those threads would be for a HTC One SV.

I encountered this problem last night when I got an error saying I needed more storage space.

Code:
#!/system/bin/sh

this was used on my HTC One V for this issue. even though it was only 130mb extra, it still helped.

^^ I was really hoping when I clicked "click to show content" there was a link to a magical program I could install to solve this issue

Lol I'm working on modifying it for this phone. Once I get it working I'll post it
EDIT: all the information I've found on creating the bind of internal storage and app storage seems like it does more damage than good

For what I could understand, the fake partition was made to be used as fat32 filesystem, so that windows could read it as a mass storage device... For me this behaviour is not really useful :/
If we were on a PC I would've erased data and fake sd partition, to make a new data partition... though I don't have the knowledge to do this safely on android.
When I'll know more, I'll do that

Will this http://forum.xda-developers.com/showthread.php?t=2432479 work with our phones?

I am curious where are the people or posts that have done this to their one x phones?
