adb goes offline after switching from passcode to passphrase

[Bill Filler]

krillin rtm image 46
- setup phone with passcode security and turn on developer mode
- then run adb devices from desktop and you can see online status and connect
- now go to system settings and change your security from passcode to passphrase
- reboot

Expected results:
adb devices should show online still

Actual results:
adb devices shows offline and you can't connect, even after reboots

Switching security back to passcode makes adb start working again

Ogra, do you have any ideas why it would depend on the type? In both cases the shadow file should have contents. The only difference *should* be an AccountsService hint field.

I used "phablet" as my passphrase. I've heard that is what causes problems..

i can not reproduce this at all, the "phablet" match is gone since before image 100, are you sure your session was fullly up ? adbd only starts after lightdm now and until that point adb devices will show "offline"
doing a run with multiple changes from password to PIN and back, also involving the password "phablet" can be seen below ... you can see the "offline" state once during boot ...

Mike: no, the code only watches /var/lib/extrausers/shadow for changes via inotify, in case it changes it restarts adbd

oh, i just noticed teh age of this bug ... it might actually have been from the time where the password "phablet" was still blocking, bill can you verify this is gone for you ?
