Cocaine::ExitStatusError when I switch from paperclip-ffmpeg 1.0.1 to 1.2.0

[casertap]

Everything is fine with the paperclip-ffmpeg version 1.0.1 but when I switch to version 1.2.0 I get this stack:

Command :: PATH=/usr/local/bin/ffmpeg:$PATH file -b --mime '/var/folders/43/t8s11k6d145c4wtwfpnbxh640000gn/T/6c84cbd30cf9350a990bad2bcc1bec5f20150205-9509-104fieg.MOV'

Cocaine::ExitStatusError - Command 'PATH=/usr/local/bin/ffmpeg:$PATH if command -v ffprobe 2>/dev/null; then echo "true"; else echo "false"; fi' returned 2. Expected 0
Here is the command output:

If i try to execute the command in my terminal:

bash: syntax error near unexpected token `then'

Forcing cocaine to the version 0.5.3 solved this issue but I do not think this should be the final solution.

[jyurek]

That isn't a valid command in bash. You're saying this works with paperclip-ffmpeg 1.2.0 and cocaine 0.5.3, but not paperclip-ffmpeg 1.2.0 and cocaine 0.5.5? Since this error is a bash error, I don't see why that should be the case. It seems more like this is a problem with paperclip-ffmpeg. What version of bash do you have? I have 4.3.30, and I see the same unexpected token error even when I run this command using cocaine 0.5.3.

[casertap]

My bash version is: GNU bash, version 3.2.53(1)-release (x86_64-apple-darwin14) so I have this and the command works:

gem 'paperclip-av-transcoder', "0.6.2"
gem 'cocaine', "0.5.3" 

some logs:

if I switch to this

gem 'paperclip-av-transcoder', "0.6.2"
gem 'cocaine', "0.5.5"

and bundle update cocaine. I get the error. paperclip-av-transcoder hasn't changed.

[jyurek]

Ah, ok. I see the error now. There was a fix for 0.5.5 that fixed the thread safety bug, but also introduced a problem where it makes commands like this syntactically incorrect: It modified the PATH on the command line. I believe I have a solution for it, though.

[casertap]

Great, I'm happy to not have open an issue for nothing :-) Good luck with that. I will test using the github version of the gem when it will be ok.

[jyurek]

Ok if you want to use that commit (84f557d) the issue should be handled.

[jyurek]

Did this work for you?

[ainame]

I've faced with same problem. And, that commit(84f557d) is good working for me.

[jyurek]

Awesome, thanks for reporting in. I'll cut a new point release tomorrow.

[ainame]

@jyurek How did it get on?

[jyurek]

Completely slipped my mind. But it's up now. Sorry about that. :)
