Vim locks up with easytags plugin #27

Closed ldx closed 11 years ago

ldx commented 12 years ago

When I use the plugin with a large project (linux kernel in my case) sometimes it just completely locks up after a few seconds. If I press CTRL-C it resumes and if verbose mode is set I can see in messages the following lines:

I don't have any local settings for easytags.

I too have this problem. After seeing this issue post, I ran my vim under verbose and got something very much like what you did. I think what happens is that the automatic tags generation is locking up the program. Is your bash shell a login shell? I'm on mac and mine is a login shell, with set shell=bash\ -l. I found that when I erased my old tags, the problem went away. I think what happened is that at some point, a different source file was being used, and somehow a tags file got dropped in a local directory. easytags found it, and then used that on a wrong file, effectively getting stuck in an infinite loop.

I don't see the recursive option in the output you gave but I'm pretty sure that your tags file contained half of the Linux kernel tags:

Initialized cache of tagged files in 47 seconds.

That's going to be slow no matter which Vim plug-in you use to manage that tags file.
