ruby-on-rails Layer Breaks TRAMP

[n4580]

Description

If the ‘ruby-on-rails’ layer is enabled, then the Password: prompt in TRAMP never shows up, and emacs freezes. I tested this on a clean install with both the master and develop branches. The master branch displays a ‘Tramp: Sending password’ message on the master branch just before it freezes. (the server I'm connecting to is replaced with <domain> below)

If you C-g, it occasionally is able to stop. The messages buffer then displays:

Tramp: Opening connection for <domain> using ssh...
Tramp: Sending command `exec ssh   -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none <domain>’
Tramp: Waiting for prompts from remote shell...
Tramp: Sending password
Tramp: Waiting for prompts from remote shell...failed
Tramp: Opening connection for <domain> using ssh...failed
Error in nil (nil): (quit)

Reproduction guide

• Start Spacemacs with ‘ruby-on-rails’ in ’dotspacemacs-configuration-layers’
• C-x C-f /ssh:<domain>:/
• If you don’t have an SSH key enabled, emacs displays the Password: prompt. If ‘ruby-on-rails’ is installed, emacs freezes.

Observed behaviour:
On the master branch, the message ‘Tramp: Sending password’ shows up. On the development branch, there is no message. In both cases, emacs appears to freeze. Hitting ‘C-g’ a few times in the GUI version can sometimes unfreeze it.

Expected behaviour:
Display a Password: prompt

Not sure it's related to the ruby-on-rails layer. I don't have it and I still have the problem.

I have the same issue and removing the ruby-on-rails layer fixes it... there must be an incompatibility somewhere there.

Hi, I'm having same issue.
And I find similar issue here: bbatsov/prelude#594,
and here bbatsov/projectile#523

This problem seems a projectile bug, and ruby-on-rails layer using projectile, so this happen.

When I remove the ruby-on-rails layer fixed it too, and when I disabled projectile-global-mode, fixed too.

Hi, After updating to emacs 25.1.1 & Spacemacs 0.200.1, this bug no longer appears.(I'm sorry but I don't know what was the cause)

The upstream issue bbatsov/projectile#523 has been closed as fixed. Can this issue be closed as well?

👍 This is an old one, I thinks it's safe to close.
