xcode5 - How to get Root privileges developing iPhone app using Xcode -


i cannot access /var/mobile/library/sms etc. in xcode if iphone jailbroken.

apple sandboxing doesn't allow root access.

a similar answer here gaining root permissions on ios nsfilemanager (jailbreak) .

but newbie. except first 2 steps, don't understand doing. great if can explain answer.

or

is there other way access /private/var/mobile/library....?

xcode: 5.0.1
device: iphone 5s ios 7.1
osx: 10.9.2

3 . create copy of executable file in app bundle.

when build project in xcode, produce output directory. varies machine, you'll have search filesystem. however, if app named helloworld, normally, you'd have directory named helloworld.app. answer referring app bundle. command line (or using mac's finder), go inside helloworld.app , make copy of helloworld executable file. normally, name copy mobilehelloworld.

4 . open original executable file , replace content script:

#!/bin/bash
dir=$(dirname "$0")
exec "${dir}"/copied_executable_name "$@"

directly launching root app fails on ios. therefore replace app's main executable script launches root executable.

i guess have described step differently. can delete file. create new script same filename (helloworld) , edit include lines above, starting #!/bin/bash. of course, copied_executable_name replaced mobilehelloworld in example.

so, ios launch script directly, instead of executable. however, script launch executable , because of permissions you've given files, running executable have root privileges.

5 . in terminal, navigate app bundle.

you're in "bundle" directory. (helloworld.app)

6 . chmod 0775 original executable file , chmod 6775 copied executable file.

issue chmod command helloworld file has 775 permissions (rwxrwxr-x). mobilehelloworld file should have 6775 permissions (rwsrwsr-x).

7 . copy app bundle /applications device. restart springboard , should go. if app doesn't launch repeat step 5 & 6 on device.

using whatever tool (i use scp since device jailbroken openssh installed), copy entire helloworld.app folder ios device. so, have folder named: /applications/helloworld.app/ contains bash script, copied/renamed executable, , other bundle resources (.png files, .xib files, etc.) app contains.

example

if have jailbroken device, install openssh , ssh phone, check out how cydia app accomplishes this. can view /applications/cydia.app/cydia script file, launches mobilecydia executable root privileges.

another way

actually, if want access /var/mobile/library, doesn't require root access. directory owned mobile user, root isn't necessary. necessary escaping normal ios 3rd-party app sandbox. that, copy helloworld.app folder , contents /applications/ folder on device. apps installed there, opposed /var/mobile/applications won't have such tight sandbox restrictions.

so, none of copying of executable, inserting bash script, necessary. steps 3 through 6 can skipped.

hope helps. sorry snarky comment.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
