My Sinatra apps work with 1.9.2-rc2. After upgrading to 1.9.2-p0 they  
terminate immediately (no output, exit status 0). Can anyone  
reproduce this? I would appreciate help investigating this, as this  
makes 1.9.2-p0 unusable for me.

Linux From Scratch 6.5, kernel 2.6.35.2  
gcc version 4.4.1  
glibc 2.10.1  
Rack uses Thin as the server backend  
All gems up to date as per this morning (2010/08/20)

Regards,

Specially the ones dealing with Thin and EventManchine

removing those from the equation, your application still works?

Sinatra’s behaviour has appeared to change in the 1.9 compatible  
versions.

I need to add the following line in my server.rb:

set :run, true

Also the template directory is no longer implicitly ‘views’, you need to  
set it yourself.

set :views, File.dirname( **FILE** ) + “/views”

No, because I never imagined that it might be necessary for an upgrade  
from -rc2 to -p0 . But since you suggest it I have now tried removing  
all of /usr/\*/_ruby_, and re-installing ruby and all of my gems. No  
change: all Sinatra apps terminate immediately, no output, exit status  
0.

I uninstalled thin and eventmachine and it made no difference. I  
assume the expectation was that the apps would fall back to the  
webrick backend?

I ran “make check” and got one error (a Timeout) and “irb” runs OK, so  
the Ruby core seems sound. Are there any other tests I could run?  
Maybe something to check the Rack core? (I am afraid I know little  
about Rack, I just use Sinatra and assume it will work.)

Has anyone managed to run Sinatra apps on 1.9.2-p0?

Regards,

Jeremy H.

Incidentally, the error message I get when I do not set the views  
directory is very strange; Sinatra says:

```
                    Errno::ENOENT at /sinatra/index

```

No such file or directory -  
[path to my Sinatra app  
directory]/\<internal:lib/rubygems/views/index.haml

```
 * file: tilt.rb
 * location: read
 * line: 122

```

[…]

It looks as though the template directory is being set to something  
ridiculous, which suggests that setting it explicitly is really a  
workaround for a bug.

I’ll see what the Sinatra devs say.

Thanks again for your help!

Yes, I upgraded a (granted, trivial) Sinatra app from Ruby 1.9.1-p378 to  
1.9.2-p0 and all I needed to cater for was the lack of the current dir  
in $LOAD\_PATH (but it shouldn’t matter if you ran 1.9.2-rc2 previously):

I’m affraid it’s a bit hard to tell what might be wrong without more  
info. Can you come up with a minimal app that doesn’t work (and share  
it with us)?

Thank you very much this solved my problem also, executing sinatra code  
had no output and nothing happened, after adding that line it started  
working again.
