using ivy as projectile completion systems breaks ivy

[CSRaghunandan]

This took me hours to figure out what was causing this bug :( ivy was working fine with projectile till yesterday. That's when things started acting really weird and buggy. I notice 2 really bad problems so far :

• find-file is broken. emacs opens the wrong directory when I execute find-file on a file (this problem whens I've at least 2 projectile projects open).
• projectile mixes up files from different projects as it's own. Here is an example :

When I execute projectile-switch-to-buffer the 4-length.hs file belong to a completely different project, yet it's identified as being part of arcade-rs project.

I'm not sure what's wrong with my emacs config that's causing ivy to break like this :( I tried tinkering with ivy and projectile config files, but I was unable to find what's causing this problem. I suspect some dependent package got updated which broke my config??

Link to config files :

• projectile
• ivy

I'm running emacs 25.1.1 on mac osx el capitan.

I haven't had any problems, and I can't guess the cause of the error.

If you want help, you'll need to provide a recipe to reproduce this with emacs -Q and:

1. Relevant elisp setup.
2. Relevant files for projects.
3. List of key sequences to reproduce the bug.

I have the same issue with find-file after the recent update, I will see if I can provide a recipe. But maybe it is other projects which are breaking ivy.

@abo-abo Sorry for the late replies. Here's how I reproduced the problem in emacs -q :

• evaluate (package-initialize)
• enable projectile -> enable ivy -> enable counsel
• evaluate (setq projectile-completion-system 'ivy)
• open at least 2 files from any two(or more) projectile projects
• use projectile-switch-project to switch from one project to another
• run projectile-switch-to-buffer (sometimes find-file opens wrong directory, and other times it works correctly. There is no surefire way of reproducing the bug. It depends on your project) and watch out for files that don't belong in the project.

@swarnendubiswas Can you check if you encounter any problems by following the steps I wrote above?

[swarnendubiswas]

@CSRaghunandan It worked during my test, no problems.

I also tried to narrow down the source, but it seems a bit non-deterministic.
