OSX: unrar needs to be set executable

[ghost]

I had this error repeatedly in my subzero log file:

#1679 | 2019-11-03  22:54:16,636 (70000319d000) :  DEBUG (config:335) - custom check failed  for: /Users/lumiere/Library/Application Support/Plex Media  Server/Plug-ins/Sub-Zero.bundle/Contents/Libraries/MacOSX/i386/UnRAR/unrar

#1680 | 2019-11-03 22:54:16,701 (70000319d000) :  DEBUG (config:335) - custom check failed for: unrar
#1681 | 2019-11-03 22:54:16,702 (70000319d000) :  WARNING (config:345) - UnRAR not found

unrar is installed on my system and correctly included in environment path both globally and for my logged in user. So, I did not get how this error message was there. Until I read the log lines more closely and realised that the unrar file within subzero is not a script to check for unrar as I had assumed. It is an additional unrar executable which subzero insists on using, ignoring the system unrar.
Problem is, the "subzero specific" unrar file is not set to be executable:

$ ls -lah /Users/lumiere/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/Sub-Zero.bundle/Contents/Libraries/MacOSX/i386/UnRAR/
total 640
drwxr-xr-x  3 lumiere  staff   102B Oct 26 05:18 ./
drwxr-xr-x  3 lumiere  staff   102B Oct 26 05:18 ../
-rw-r--r--  1 lumiere  staff   319K Oct 26 05:18 unrar

So. Now it makes perfect sense subzero is complaining.

I ran:
$ chmod ug+x /Users/lumiere/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/Sub-Zero.bundle/Contents/Libraries/MacOSX/i386/UnRAR/unrar

This fixes the issue. Verified error messages are gone from logs.
But unless fixed within subzero, it likely needs redoing manually on each subzero update.

Did you download the zip instead of a direct check-out of the repository? The flags are correctly set as long as you properly check out the repository.

You can try the latest develop-2.6 branch. It sets the executable permissions explicitly.

Thanks!

I just changed the permissions manually, hoping it sticks across updates. It's a year or 2 ago since I installed sub-zero, it seems to update itself.

The post here was mainly to let you and others know. I've seen several report the same error message. Might help them save some time debugging / help you fix.

Thanks again for making sub-zero, it's awesome :)

You're welcome. If you want to try the develop-2.6 branch and see whether it works, that'd be awesome.
