Listener doesn't recognize changes on samba share since v1.0

[mkoentopf]

Hi there,
I've a setting on a linux node with mounted samba shares (from windows).
I use listen to watch for new files in a hot folder (on the samba share).
Until the version 0.7.3 there was no problem. Since version 1.0.0 it doesn't work.
Tests with local folders on the node were successful, with a samba share folder not.
Any ideas?

Thx, Matthias

rb-inotify has been included after 0.7.3 and is now automatically used, maybe you need to force_polling to make it works with samba.

[mkoentopf]

I've tried it with :force_polling => true. No success.

[thibaudgg]

Mmm, I don't see what could have cause that. The logic have mostly stay the same between 0.7.3 and 1.0.0.

Maybe you could already try with the completely rewritten v2.0 branch, it's only works with polling at the moment and the DSL has been a little bit simplified but example.rb should work.

[mkoentopf]

Cool. I'll try v2.0 when I'm back from my holidays.
I'll let you know.
Thanks for your help,
Matthias

Polling does work for me on a samba-share with v2.0.
When will the linux-adapter be ready for using on that branch?

[thibaudgg]

@webwurst great news, linux/os x adapter are next on my list, so it should be soon (1-2 weeks).

[webwurst]

Cool! 👍

When watching several hundred files polling does not work well.
It seems not to react at all, although cpu-usage ist constantly quiet high.

Is it possible to get some debug-infos to see what's going on?

Will be happy to test the linux-adapter :)

[thibaudgg]

@webwurst polling could be quite cpu-intensive with a lot of files, try to ignore some path if possible. There is no debug info implemented at the moment, PR is welcome!
I'll start darwin=adapter now, I'll ping you when linux-adapter is ready to be tested.

[thibaudgg]

@webwurst just update v2.0 branch with first version of linux-adapter, could you give it a try please? There's still some issues on jruby & rbx https://travis-ci.org/guard/listen be warned!

[webwurst]

@thibaudgg thx!
Works fine for me so far 👍

I noticed one thing: Whenever i stop the listener via ctrl+c it gives me Couldn't cleanly terminate all actors in 10 seconds!.
Even if nothing has happened on the file-system.

[thibaudgg]

Yeah, I need to take care of stopping cleanly Celluloid actor.

[mkoentopf]

I've tested the v2.0 branch of listen with (and without) a samba share on a linux node.
The good news is: They behave the same with or without the samba share.
With force_polling it is a little bit strange. If I touch a new file it's ok, but if I use echo 'bla' > test.txt I've got double messages with this code : l = Listen.to('/home/test', :force_polling => true){ |modified, added, removed| puts "modified #{modified.inspect}"; puts "added #{added.inspect}";} l.start.
The linux adapter crashes if stop the listener and if I add a new file both fields modified and added are filled.

[thibaudgg]

@mkoentopf which ruby are you using?

[mkoentopf]

Hi, I'm using ruby-1.9.3-p429

[thibaudgg]

interesting because spec pass on that platform for file addition on travis

• https://github.com/guard/listen/blob/v2.0/spec/integration/listen_spec.rb#L24-L28
• https://travis-ci.org/guard/listen

as you can see it's still a work in progress, thanks for your feedback!

[mkoentopf]

Yes, the test with touch is working, but if I do this: echo 'bla' > test.txt, then I've got a double message.

[thibaudgg]

Nice, I'll add a spec and fix that. Thanks!
