Toybox vs Busybox

[DocSniper]

AOSP switched from busybox over to toybox, so it would be great if you could check for busybox and/or toybox. Because on newer ROMs like CM13 busybox is no more detected and a workaround for this is to set toybox as busybox in the options menu. But auto detection would be a good feature ;-)

thanks for notifying me :) can you check if auto-detecting works with this: https://drive.google.com/file/d/0B0bNUNWd2wPPaF9POVhaZXY5eHM/view?usp=sharing

Your test APK is working well, toybox is detected. Thanks :-)

[jensstein]

great :) can you confirm that everything works as it should? just from reading the android source code it doesn't seem to have chown for example. chown is present in the normal toybox (http://www.landley.net/toybox/status.html) so maybe i'm just not looking the right places. but in android 6 it seems to be provided by bionic. the programs used with busybox now are:

cp -r
chmod -R
chown -R
stat
sed -nre
[[
basename
mkdir
rm -r
touch
pkill
grep

(the flags are important too)

so it's actually only if all of those are available natively on android 6 that setting toybox as oab's busybox would make sense. some of them are also normally present on older android versions in the toolbox implementations but used in the busybox implementations in oab for example because of lacking features in toolbox.

You are right, there seems to be a problem with restoring the data even if logcat reports success.

The commands seem to be there, maybe this helps:

cd /system/bin

ls -l

[jensstein]

thanks. it's probably because [[ is missing from toybox. could i get you to try this version which uses test instead: [deleted]

[jensstein]

sorry, i made a mistake. please try this one: https://drive.google.com/file/d/0B0bNUNWd2wPPQzFtYjUtRlREMVU/view?usp=sharing

[DocSniper]

The files are restored and the chcon seems to work, but there is a problem with the chown, not all directories and files are set to the correct owner and group.

[DocSniper]

A manual chown -R solved the problem.

[jensstein]

could you give me an ls -lRZ of a restored data directory (where the restore didn't fully succeed)? and please try running this line and watch the output: for dir in $packagedir/*; do if toybox test toybox basename $dir != "lib"; then toybox chown -R $uid:$gid $dir; toybox chmod -R 771 $dir; fi; done where $packagedir is a data subdirectory (e.g. /data/data/dk.jens.backup) and $uid and $gid are the user and group ids of that package. also, with chcon did you mean chmod or restorecon, because chcon is not called.

[DocSniper]

First, yes I meant restorecon not chcon, can remember the discussion about what would be the best choice. ;-)

The small script hasn't made any output and didn't change the rights and owners. I modified it, after that it was working so far:

First run:

for dir in /data/data/dk.jens.backup/*; do if test basename $dir != "lib"; then chown -R u0_a118:u0_a118 $dir; chmod -R 700 $dir; fi; done

ls -l

drwx------ 2 u0_a118 u0_a118 4096 2016-01-09 16:04 cache drwx------ 2 u0_a118 u0_a118 4096 2016-01-10 13:02 code_cache drwx------ 2 u0_a118 u0_a118 4096 2016-01-09 19:21 shared_prefs

Second run:

for dir in /data/data/dk.jens.backup/*; do if test basename $dir != "lib"; then chown -R u0_a117:u0_a117 $dir; chmod -R 771 $dir; fi; done

ls -l

drwxrwx--x 2 u0_a117 u0_a117 4096 2016-01-09 16:04 cache drwxrwx--x 2 u0_a117 u0_a117 4096 2016-01-10 13:02 code_cache drwxrwx--x 2 u0_a117 u0_a117 4096 2016-01-09 19:21 shared_prefs

[jensstein]

so the line you label first run fails and second run succeeds? but am i correct that the only things you have changed are the permissions and ids? i can't really see how that should have helped when the problem was that it didn't set ownership at all. please describe what you did. also please run the commands from explicitly from toybox since that's how they are run in oab. so test should be toybox test. and please use the -R flag on ls every time (maybe choose a different app with fewer files to show up in the output).

does android 6 not have a lib symlink in the data subdirectories? try if this one works maybe: https://drive.google.com/file/d/0B0bNUNWd2wPPakM5QVZiZWNUTDA/view?usp=sharing

[DocSniper]

No, both lines succeeded, I just wanted to show you that. I removed the 3 appearances of toybox in your snippet. The new test version of your app worked well.

[jensstein]

ok, so removing toybox from the line fixed it? i guess it's then either toybox test or toybox basename which is the problem because the apk i linked runs toybox chown and toybox chmod. but it seems a little unlikely that should be the case. if you find out what's wrong, it would be nice to know, but i think i'll go with the fix in the linked apk if there aren't any problems with it. thanks :)

[DocSniper]

Yes, removing fixed it.

Tested the following:

toybox basename /sdcard

sdcard

if toybox test toybox basename /sdcard != "lib" ; then ls -l /sdcard ; fi

(no ls output)

Actually I saw after restoring some data that the lib symlink was/is missing, the link looks like this on Android 6: lrwxrwxrwx 1 root root 30 2016-01-10 10:05 lib -> /data/app/APPname/lib/arm

[jensstein]

ok, so toybox test could be the problem. what happens if you run something that obviously should succeed like if toybox test 1 = 1; then echo ok; else echo fail; fi? if that's not the problem then it might be something with the backticks. please try this: if toybox test "$(toybox basename /sdcard/)" = "sdcard"; then echo ok; else echo fail; fi and just to rule out some misbehaving of the shell if: toybox test "$(toybox basename /sdcard/)" = "sdcard" && echo ok || echo fail

is the lib symlink also missing if you only restore the apk and not the data? if not does it then disappear when data is restored? and if it is missing at first, is it then different if you install an app manually by clicking the apk in the oab subdirectory (after it has been uninstalled)?

[DocSniper]

All three command lines give me a "fail".

Will do the other tests later. ;-)

[DocSniper]

Was too quick, number 3 gives me:

if: toybox test "$(toybox basename /sdcard/)" = "sdcard" && echo ok || echo fail

/system/bin/sh: if:: not found fail

[jensstein]

ok, so unless i'm going crazy i think we can say that toybox test (or the implementation you are using at least) is broken. unless it has something to do with the shell the commands are running in. to determine which version you could run strings /system/bin/sh | grep VERSION. mine reads "KSH_VERSION=@(#)MIRBSD KSH R50 2014/10/07".

your error on number 3 is just because of my confusing formatting. you should just run toybox test "$(toybox basename /sdcard/)" = "sdcard" && echo ok || echo fail which i also think you did the first time around. it was to establish whether if had anything to do with it.

[DocSniper]

I'm using CM13, latest nightly.

strings /system/bin/sh | grep VERSION

KSH_VERSION=@(#)MIRBSD KSH R50 2015/04/19

Here your modified third command:

toybox test "$(toybox basename /sdcard/)" = "sdcard" && echo ok || echo fail

fail

[DocSniper]

When I start toybox it gives me "test" as included command, so it seems you are right, it's broken.

Without toybox in front of test:

test "$(toybox basename /sdcard/)" = "sdcard" && echo ok || echo fail

ok

[jensstein]

ok, if you could report that in the appropriate place that could be helpful if we need test in the future. now we just need to figure out what's happening with the lib symlink :)

[DocSniper]

Cyanogen does not allow to report bugs before any stable version was released, so I'm unsure were the best place to report this error could be.

Will test the lib problem later, actually we have some visitors for coffee and cake.

[jensstein]

ah ok, i don't know where the best place to report it is either. i might try to cross-compile the toybox source from http://www.landley.net/toybox/ and see if the problem is there too. and just take your time with the lib thing :)

[DocSniper]

Tested all the three cases but no lib symlink. So I installed a new app from f-droid, but no lib link?!? See yourself:

/data/data/cz.martykan.webtube # ls -l total 40 drwxrwx--x 2 u0_a94 u0_a94 4096 2016-01-10 19:22 app_cache drwxrwx--x 5 u0_a94 u0_a94 4096 2016-01-10 19:24 app_webview drwxrwx--x 3 u0_a94 u0_a94 4096 2016-01-10 19:22 cache drwxrwx--x 2 u0_a94 u0_a94 4096 2016-01-10 19:24 code_cache drwxrwx--x 2 u0_a94 u0_a94 4096 2016-01-10 19:23 shared_prefs

[DocSniper]

But this one is having the link:

/data/data/jackpal.androidterm # ls -l total 32 drwxrwx--x 2 u0_a62 u0_a62 4096 2016-01-10 13:40 app_HOME drwxrwx--x 2 u0_a62 u0_a62 4096 2016-01-10 13:40 cache drwxrwx--x 2 u0_a62 u0_a62 4096 2016-01-10 14:11 code_cache lrwxrwxrwx 1 root root 39 2016-01-10 13:40 lib -> /data/app/jackpal.androidterm-1/lib/arm drwxrwx--x 2 u0_a62 u0_a62 4096 2016-01-10 13:41 shared_prefs

[DocSniper]

With the second app it was like this:

• after restoring data only --> no lib link
• after restoring the app --> lib link is created

[jensstein]

ok, so it's probably only created if it's actually needed. can you try if the apk from https://github.com/jensstein/oandbackup/issues/116#issuecomment-170345098 can restore an app with a lib symlink?

[DocSniper]

I performed the last test with this program version.
