877356 - Enable fanotify on unagi kernel

Status: RESOLVED INVALID

(Firefox OS Graveyard :: General, defect)

Description

[Jason Smith [:jsmith]]

Build: B2G 18 5/29/2013
Device: Unagi

STR

1. Lower the device's storage down to 15 MB
2. Go to http://jds2501.github.io/webapi-permissions-tests/largeappcache.html in the browser
3. After downloading is finished, check the application storage

Expected

Application storage should not go below 5 MB. Additionally, upon hitting the 5 MB limit, the user should be notified that they can no longer write to device storage (low storage theshold was hit).

Actual

Application storage ends up at 16 KB. Additionally, no low storage warning was present.

On the second try, I got the application storage down to 0 bytes.

Comment 2

[Jason Smith [:jsmith]]

Appears to be 1.01 affected as well.

Just for more additional proof:

$ adb shell df | grep /data
/data                    2G     2G     8K   4096

Those columns go - Size, Used, Free. Which means I've got 8 KB left.

And even more proof:

Launching the calendar app with 8 KB present causes a whitescreen of death. So yeah, we didn't protect ourselves apparently.

Comment 6

[Jason Smith [:jsmith]]

Apparently this only works if bug 866243 is enabled, which is not true for unagi.

Actually, I can reproduce this bug on inari as well on a 5/29 1.01 build. Let me close this bug and fix what I filed here since I morphed the bug.
