OpenColorIO config cannot be set unless it has write permissions

[electricart]

Hello. I believe this to be a bug. Currently when trying to set an OpenColorIO config on macOS, Affinity Photo requires write permission to the config file. However it should only need read permission.

1. Are you using the latest release version?
   Yes. 1.8.3
2. Can you reproduce it?
   Yes. See below.
3. Does it happen for a new document? If not do you have a document you can share that shows the problem? https://github.com/imageworks/OpenColorIO-Configs
4. If you cannot provide a sample document then please give an accurate description of the problem for example it should include most of the following:

•    What is your operating system and version (Windows 10, OSX Mojave, iOS 12 etc)? macOS 10.14.6 (18G4032)
•    What happened for you (and what you expected to happen) See below
•    Provide a recipe for creating the problem (step-by-step what you did). See below
•    Screenshots (very handy) or a screen capture/video. See below
•    Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers. No
•    Did this same thing used to work and if so have you changed anything recently? (software or hardware) No

Steps to reproduce.

1. Check permissions are read-only on config.ocio

$ ls -al /Library/Application\ Support/OpenColorIO/aces_1.2/config.ocio
-rw-r--r--  1 root  admin  170835  5 Apr 02:41 /Library/Application Support/OpenColorIO/aces_1.2/config.ocio

2. Go to Preferences --> Colour

3. Set OpenColorIO Configuration File - in our case /Library/Application Support/OpenColorIO/aces_1.2/config.ocio (downloaded from https://github.com/imageworks/OpenColorIO-Configs )

4. Infinity Photo asks to restart the application

5. Go to Preferences --> Colour

6. No OpenColorIO Configuration file is set anymore. It has forgotten what was just set

7. Set permissions to read/write

$ sudo chmod 666 "/Library/Application Support/OpenColorIO/aces_1.2/config.ocio"
$ ls -al /Library/Application\ Support/OpenColorIO/aces_1.2/config.ocio 
-rw-rw-rw-  1 root  admin  170835  5 Apr 02:41 /Library/Application Support/OpenColorIO/aces_1.2/config.ocio

8. Go to Preferences --> Colour

9. Set OpenColorIO Configuration File - in our case /Library/Application Support/OpenColorIO/aces_1.2/config.ocio

10. Restart Affinity Photo

11. Config is now set

 

As far as I am aware, Affinity Photo should not require write permissions to the config.ocio file. It should only require read permssions as it should not need to modify this file. Therefore I believe this to be a bug. Please let me know if you need any more information.

thanks,

Tristan.

Hi @creamelectricart,

Thanks for spotting this. I logged it with our developers.

@Gabe No worries. Thanks for passing it on.

I haven't checked to see if the same bug is affecting the Windows version or not, but it might also be worth checking.

Thanks again,

Tristan.
