Complains a lot when tempdir vanishes

[eevee]

I'm on Arch and subject to the whims of systemd, which apparently include deleting anything older than ten days from /tmp whenever it feels like it.

If this happens, any vim process I've left idle for more than ten days will start spewing "Can't open file" errors, because the underlying tempdir no longer exists. Nothing important must be there, because recreating the directory manually makes everything work merrily again.

I could turn this behavior off, but given that /tmp is intended to be volatile, perhaps gitgutter should notice when its tempdir falls out from under it, and quietly recreate it?

I can see two possible solutions here.

First, do as you suggest and have the plugin catch the "can't open file errors" and recreate the directory itself.

Second, set $TMPDIR in your vimrc to a temporary directory you have more control over, e.g. $HOME/tmp. See :h tempfile and this vim_use discussion for some background.

Would you be able to try the second option and see whether it solves the problem for you?

Hmm. It would presumably solve the problem, but then I'd have another temp dir somewhere slowly being filled with things I'd have to remember to delete, which sort of defeats the purpose of a temp dir. Maybe if I added a systemd job to empty it regularly for me... ;)

[airblade]

I see your point ;)

I'd still prefer to find a general solution to this rather than add code to this plugin, because it's a general Vim problem. It might be worth your posting a question on vim_use. In the meantime I'll keep digging and see if I can find anything.

Did you make any progress with this?

It would be nice if vim-gitgutter handled this situation but I think really it's vim's responsibility. So I'm going to close this.

I'm not averse to including a patch which remedies this if it's simple and small.
