Spring hangs when it can't connect to the server.

[jcoyne]

It should have a timeout.

This is happening when the project directory is moved.

[jonleighton]

Can you provide steps to reproduce please?

[jcoyne]

I'm unable to reproduce this now. I was using the engine_cart gem, which generates a rails app in the tmpdir and then moves it. It does this to assist in testing rails engines, so it's always generating an app with the same application_id. Somehow the socket was getting blocked. Perhaps by an old version of the application? I think this is a pretty rare edgecase, so I'm closing it until I encounter it again.

Same issue here. Running bin/spring just hangs. Ctrl + C spits out this:

Stopping and running it again seems fixes the issue:

$ spring stop
$ bin/spring

@demisx's solution worked for me, spring stopped working when I deleted the project's directory.

[krukid]

@demisx same stuff happened when I renamed my rvm gemset, restarting spring helped

[demisx]

@krukid Glad it helped. I find myself needing to restart spring at least once a week or weird things start happening.

[tomharrisonjr]

I am on spring 1.1.3 and just ran into this problem while running rails generate mailer Foo -- symptoms were a red herring, as it appeared to relate to a gem we are building, making it a long day of chasing my tail. Then spring started hanging.

If helpful, we're working on projects in Rails 4.0 and 4.1 at the same time (not to mention several rubies). Also using RubyMine for development.

[relistan]

Installing carrierwave somehow caused this for me. Also had to stop spring.

[jdelStrother]

I think I know how to reproduce this - dump a load of stuff on STDOUT while the server is starting up. eg puts caller.inspect in config/application.rb. Clients trying to connect to spring will then hang on verify_server_version

[ssiddique-info]

it works thank you.

[drymar]

It's help me too. Thanks 👍

$ spring stop
