[mako] Size of the pictures is 1 byte if zoom level is slightly over 50%

[Jean-Baptiste Lallement]

If zoom level is slightly over 50% then the size pictures are corrupted and their size is 1byte:

For example content of /home/phablet/Pictures:
[...]
-rw-rw-r-- 1 phablet phablet 1 Jun 3 20:58 image20140603_0010.jpg
-rw-rw-r-- 1 phablet phablet 480438 Jun 3 20:58 image20140603_0011.jpg
-rw-rw-r-- 1 phablet phablet 784018 Jun 3 20:58 image20140603_0012.jpg
-rw-rw-r-- 1 phablet phablet 1 Jun 3 20:59 image20140603_0013.jpg
[...]

TEST CASE:
1. Open the camera-app
2. Set the zoom level with the slider to slightly more than 50%
3. Take a picture

ACTUAL RESULT
The picture is corrupted and its size is 1 byte
# stat /home/phablet/Pictures/im
  File: ‘/home/phablet/Pictures/image20140603_0013.jpg’
  Size: 1 Blocks: 8 IO Block: 4096 regular file

EXPECTED RESULT
The picture is valid and correctly zoomed

JB, do you mind providing a logcat of when it happens?

[Florian Boucault (fboucault)]

Also, on what device did you test?

[Brendan Donegan (brendan-donegan)]

I could reproduce this on mako at least. Here's the logcat:

[Florian Boucault (fboucault)]

Easily reproducible on mako, not on other phones.

[Ugo Riboni (uriboni)]

Mako has 60 zoom levels, and taking pictures with zoom level 29 triggers the bug.
Krillin has 16 zoom levels and none of them triggers this bug.
