Thumbnails, libjpeg: recoverable error: Invalid SOS parameters for sequential JPEG

[rajil]

Hello,

I have some photos taken from a phone which render fine in gwenview and gimp, but give an error in owncloud. The errors I get in the owncloud.log file is
"imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Invalid SOS parameters for sequential JPEG"

The web UI is unable to show the thumbnail.
The relevant packages i have installed are php56-gd-5.6.17 and jpeg-turbo-1.4.2

Google returned this
golang/go#3916

With the image that is linked there I can reproduce the error:

{"reqId":"vFZDhvb9KbRyDLVYHRnt","remoteAddr":"::1","app":"PHP","message":"imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Invalid SOS parameters for sequential JPEG\n at \/Users\/morrisjobke\/Projects\/owncloud\/master\/lib\/private\/image.php#515","level":0,"time":"2016-01-25T08:26:49+00:00","method":"GET","url":"\/master\/index.php\/core\/preview.png?file=%2Fasd%2Fxx.jpg&c=1338e8260789f433aefdda62641e5109&x=64&y=64&forceIcon=0"}

Workaround:

ini_set ('gd.jpeg_ignore_warning', 1);

See http://php.net/manual/en/image.configuration.php

Thanks @MorrisJobke . It had already been added to Gallery(+), but would be good to have it enabled in core. Where though?

I'd advocate for

core/lib/base.php

Lines 471 to 476 in 308396b

	/**
	* Try to set some values to the required ownCloud default
	*/
	public static function setRequiredIniValues() {
	@ini_set('default_charset', 'UTF-8');
	}

. Any objections?

[oparoz]

Sounds good to me :)
