Strace for Android

Everybody loves strace !
So am I, thats why I compiled a static one you can use on any Android or even.. any ARM Linux system
It's unmodified, compiled with buildroot.
Download it here:
http://project-voodoo.org/downloads/dev-tools/debug/strace.tar.gz

[Q] kernel compiling,zImage packing and unpacking

first time post a thread~
i got a samsung galaxy tab 7' koran version shw-m180l.
1. as i downloaded source code from source.samsung.com. there are two folders: platfrom and kernel . i'm wondering if the source code of initramfs is out there in the platform folder or in the kernel folder?
2.i got a 3M size kernel "zImage" after cross-compile on fedora 16 x86_64 follow the readme instruction posted with the source codes，and tar -cf it then flashed into my tab .but it could not working properly .the official zImage is about 7M size; i guess the reason why mine zImage is so much smaller than the official one is that i didn't packed the initramfs inside.here is thread of unpacking zImage，i could not unpack even the official zImage using unpack-bootimg.pl .and then i tried to modifiy the zImage using a hexEditor ，sadly find no magic number 1F8B for gzip around 2k data。i guess samsung is using an unusual way to packing zImage(just like samsung develeped the rfs file system instead of using the common yaff2 file system)? if then , how can i unpack ing the zImage?
3. thanks to here some one write a tool reading pit file ，the result is the same with what Heimdall reads in download mode ：

[Q] Android 4.0.4 and high cpu usage of system_server with autorotate on

Hi,
i have nexus S with IMM76D_deodexed. I had preciously 4.0.3, then 4.0.4 - IMM26. Now IMM76D, CWM.
With IMM76D I hoped all will be solved, but not.
before updating to IMM76D I did:
back to factory reset
format SD card
clean Dalvik
clean /system except /boot
Now i think, I'm only one, who has infamous autotate high cpu usage bug
- without autorotate (cpu usage is normal):

Hey dude,
No, you are not the only one with the auto-rotate bug. I have it too, but im on stock, non rooted ICS 4.0.4 for the Nexus S. But I can't help you either
Just wanted you to know that you are not alone.

what are the symptoms of this bug? every since i loaded 4.0.4, my phone seems to be eating up battery like crazy, also freezing up and shutting off randomly. sounds like it could be my problem.
should i just disable the auto-rotate setting for now?

It's worth a try, you can't damage anything if you do

I've been using the attached patch (against the stock ICS 3.0 kernel source, but should apply to any Nexus S 2.6.35 ICS or 3.0 kernel), which throttles the orientation sensor device and reduces system_server CPU usage to a more reasonable 2-3% (similar to Gingerbread).

Thanks for confirmation.
based on the confirmation there is new bug from me:
xxxttp://code.google.com/p/android/issues/detail?id=29965
For quick autorotate on and off i'm using quick app:
xxxttps://play.google.com/store/apps/details?id=com.friedflow.autorotate&feature=order_history
Thanks for the kernel patch... but i think, i will not building kernel...
i don't understand, why these bugs are not fixed yet... Like USB slow file transfer...

How's this patching working out for you? Any side effects to watch out for? Also, did you find anything more refined along the way?
Thanks!

I've been carrying this patch since December with absolutely no ill effects, and given that it works, I haven't bothered to look for better solutions ...

[Request] any method for resizing A13 Tablet partitions?

I have a tablet a13 allwiner , it shared like this
nanda (bootloader) :32 Mb
nandc (system partition) :512 Mb
nandd (data partition) :1.2 Gb
nandg recovery :32 MB
nandj (SD card or internal storage): 1.6Gb
i want to modify size to have (like i found it in other firmware for another tablet based a13 cpu)
512 system
512 data
and 2Gb or above for SDcard
i have extract the original firmware with a10 kitchen and change the content of COMMON _SYS_CONFIG000000.hdr and rebuilding
i have change the file for attempting this size like a want and i see in other firwmare
but after rebuilding and flashing the tablet start with black screen( what happen ?)

is there any way to do it by flashing it with factory firmware and changing the partitions size ?

Not that I know of

i found a rom (for icoo D50 lite) which its parted to 512 system and 512 data i try it by flashing my tablet , and try to rewrite my bootloader, boot.img and restoring system and data but i found only the problem the firmare manage only 9 partition but my original firmware and files manage 10 parition , then my internal storage will be null 0 byte cause boot point on nandj but the last partition is nandi ,

i do it by moding boot.img all thing is correct only the ft5_ts.so touch screen driver can t be loaded caus the firmware buid 1.45r
i think , it s possible to do it. but what the way to rezise partition with cooking new image .
link for icoo d50 lite http://www.pandawillforum.com/soft/ICOO D50 Lite firmware 20120801.rar
NB : juste i extract the original image and cooking it again without any modif. it aint boot (black screen)

My first question is why do you want to do this ? If you want a 10 Partition firmware you need the 10 Partition structure... and if you want to load a 9 partition frmware you need the 9 Partition structure....
If you are trying to do this in order to make a particular firmware work on your device i would recommend changing drivers in the one you want to match your hardware and compiing them into a livesuite image for flashing.
If you are trying to mix them for more efficient use of space it likely will require that you insure all references to the block devices point to the correct partitions.... within the firmware I do not know all of the references but I do know that they are referenced in the Boot.img in several files incliding the init.sun5i.rc and a couple of the uevent files. In the system folder one place im sure refers to at least the internal and external SD cards and any usb storage devices is the vold.fstab in /system/etc there are likely other places in the system that reference the actual block devices. I would start by making sure they are all properly pointing to the correct nandx partitions..

[UTILITY] STrace 4.8 - Ultimate debugging utility now ported to Android !

about Strace
Android provides Logcat for tracing and debugging Apps , Logcat provides too short information and limited apps also programs has to support logcat or there wo'nt be any log ! this makes Android logcar be completely un-useful in large/advanced programs .
strace is a debugging utility to monitor a program system calls or signals it receives . strace is used while we want to find the reason a program crashes or finding out what causes a process not to work as expected .
strace is much more powerful than Android Logcat . unlike logcat , any process may be monitored by strace also there is no need to rewrite a program for support of strace
usage & downloading
I have ported strace to Android and it works without any bugs
download the lastest binary from this post , move it to /system/bin and set permissions to 755 .
strace has a lot of options you can find by running it using :
Code:
strace --help
most common functions are :
1- using strace to monitor a command :
Code:
strace echo hello
2- using strace to monitor an App/process :
Code:
strace -p 123
(123 is a example , use any other PID you wish )
here is an example of running strace with hello command :
Code:
ALIREZA | strace echo hello

and now lastest download link :
Download Strace 4.8 from here
license
strace is a free software, you may download source of strace from here

Only 4 downloads ?!

Segfault any attemp to use it!
Running on LG P500 (ARMv6) cm-10.2
OK, guess what? Already have it on /system/xbin and that does work.

Very nice tool/utility man.....
will try it to solve issues on my roms...
thanks man :good:

Dido, I needed such a tool too.
Thanks

Would like to try it, but the download link requires me to sign up for an account. Can't you make this available some other way?

you dont need an account to download. Between the 2 ads is the download button

Thanks, I got it! I really hate these purposely misleading download sites.

Once i run strace -p 123 it will come back
Code:
strace: attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted

I said :
(123 is a example , use any other PID you wish )

You must use the a valid PID , 123 is an example .
For getting PID of an APP/Process , use the this command in terminal :
Code:
ps | grep "abc"
instead of abc , write the process name you want ! for example :
Code:
ps | grep "com.android.acore"
then search for PID in the output and use it with strace !

You need to be root to attach to already running processes.
I also find the "-f" option useful for more complex executables (which fork new processes). "-o" to write the output to a file can be useful if there is much output.

Can I use this in the tool in my signature please?

Sweet!

Huh? It's a well-known, standard unix utility, being a part of Android distribution since Android 1.6 (although, only in debug builds)...
See https://android.googlesource.com/platform/external/strace/ (note all the branches on the left)
It's good to make people aware of it, though, as it's a very useful tool for debugging some kinds of issues.

I haven't seen it, but its just in android sources and only in debug builds for debugging the android but This is a standalone build of latest STrace suitable for developers to debug their APPs . Developers will not download and compile whole android for just having a dynamicly linked strace .
Another thing , why most of you are saying its a well-known/popular linux utility ... , did I say it is not ????

Segfaults on Razr i (intel atom x86).

But that's something that's popular to do here, a lot of people download the sources and compile the ROMs they run from source. Additionally, this is probably included in every custom ROM out there. My CM10.2 install has the utility built in.
There's no need to be defensive, the RD that's replying to you is just providing links for more reading. The better informed the users of this site are, the more cool stuff we'll see in the future.
Thanks for your strace build!

This does not work on X86 based platforms.

There're quite a few blog posts on the net about compiling strace from source.
Eg. http://discuz-android.blogspot.com/2008/01/create-google-android-strace-tool.html
I've created a precompiled tgz package that you can extract into the root of your filesystem and it'll put strace into /data/local (i.e. /data/local/bin/strace).
http://muzso.hu/node/4869
I prefer my utilities in /data/local.
