Graphics with long name doesn't work

[poborin]

Bug Report

SDLShow does not display images with long image names. E.g. rso_start_screen_static_map_image_name.png

Reproduction Steps

1. Create and upload SDLArtfork with rso_start_screen_static_map_image_name.png name
2. Create an SDLShow with image that uses that name
3. Send an RPC

Expected Behavior

Image displayed on a headunit

Observed Behavior

Image not displayed on a headunit

OS & Version Information

• iOS Version: 10.3.2
• SDL iOS Version: 4.5.5
• Testing Against: TDK-X2 U2-221
• Firmware: 16074

Test Case, Sample Code, and / or Example App

let imageName = "rso_start_screen_static_map_image_name.png"
let image = UIImage(contentsOfFile: imageName)
let artwork = SDLArtwork(image: image, name: imageName, as: .PNG)
sdlManager.fileManager.uploadFile(artwork) { _, _, _ in
    let show = SDLShow(withTitle: "line1", message1: "line2", message2: "line3", alignment: .left_ALIGNED())
    show.graphic = SDLImage(name: imageName, of: .dynamic())
    self.sdlManager.send(show)
}

Hi @poborin, thanks for making this issue. Has this worked before and a recent update is causing it to not work? Is the file manager completion handler coming back with any sort of an error? Is the Show?

Hi Joel,

I'm not sure if it was working in previous SDL versions. The file manager does not return any error neither Show rpc response.

We've done testing and the issue appears to be limited to the Ford ecosystem and is not an SDL issue, we've reported the issue to the Ford team and will close this issue. You can see this by testing against Manticore. We'd recommend shortening the name of the file for now.

Hi Joel,

I think this is wrong. SDL SDK should prompt an error at least. There is no visibility whenever Ford supports it or not.

On the top of my head I do not remember anything in the doc that saying "the image name should not be longer then x characters". And even if it does then I definitely expect an error form the SDK.

Hi @poborin,

We had a discussion about this today while discussing this issue. SDL itself acts as a proxy between the mobile application and the head unit. The limitation here in particular isn't a limitation of SDL but a limitation of the QNX filesystem that Sync is built on. We are going to add comments on the affected classes such as SDLFile and SDLArtwork that if building for that system that you will be expected to adhere to its limitations. It would not be suitable for the library to make this warning for a developer if the system the are connecting to does allow longer file names. It is up to the implementor of core / hmi to return clear warnings for their implementation of the system.

I hope this helps bring some clarity.

Hi Brett,

Thanks for the comment. It sounds much more clear now.
