Description

When opening up unstaged files in fugitive, I'll sometimes see the following error message:

Error executing luv callback:
...e/pack/packer/start/gitsigns.nvim/lua/gitsigns/async.lua:76: The coroutine failed with this message: ...pack/packer/start/gitsigns.nvim/lua/gitsigns/watcher.lua:86: attempt to index a nil value
stack traceback:
        ...pack/packer/start/gitsigns.nvim/lua/gitsigns/watcher.lua: in function <...pack/packer/start/gitsigns.nvim/lua/gitsigns/watcher.lua:59>
stack traceback:
        [C]: in function 'error'
        ...e/pack/packer/start/gitsigns.nvim/lua/gitsigns/async.lua:76: in function 'cb'
        ...e/pack/packer/start/gitsigns.nvim/lua/gitsigns/async.lua:113: in function 'callback'
        ...k/packer/start/gitsigns.nvim/lua/gitsigns/subprocess.lua:98: in function <...k/packer/start/gitsigns.nvim/lua/gitsigns/subprocess.lua:86>

It doesn't have a noticeable effect on the buffers as far as I can tell; even the signs in the gutter are still there. It's more just annoying/alarming than anything else.

Looking at the code, it gets caught on this line:

gitsigns.nvim/lua/gitsigns/watcher.lua

Line 86 in 5d73da7

cache[bufnr]:invalidate()

So I assume that it's cache that is the nil value attempting to be indexed. Strangely though, cache is used and indexed in the same function, just a few lines up:

gitsigns.nvim/lua/gitsigns/watcher.lua

Line 68 in 5d73da7

local git_obj = cache[bufnr].git_obj

So somehow cache becomes nil between those two lines, but I can't figure out why. Nor can I recreate the issue with any consistency at the moment. I'll try adding to this issue if I find more information or anymore reason

Neovim version

NVIM v0.9.0 Build type: RelWithDebInfo LuaJIT 2.1.0-beta3

Operating system and version

Manjaro 23.0.0

Expected behavior

Not have an error throw when diffing files

Actual behavior

I get the error message listed above. I can hit enter, move on, and nothing appears to be wrong.

Steps to reproduce

Can't find a consistent reproducer unfortunately. I basically diff and stage files until the error occurs.

I'm getting this consistently, any time I use Git in a project where I have a file open in Neovim. I can simply open a file and run git status and get the following similar error:

Error executing luv callback:
vim/shared.lua:620: s: expected string, got nil
stack traceback:
        [C]: in function 'error'
        vim/shared.lua:764: in function 'validate'
        vim/shared.lua:620: in function 'endswith'
        ...pack/packer/start/gitsigns.nvim/lua/gitsigns/watcher.lua:125: in function <...pack/packer/start/gitsigns.nvim/lua/gitsigns/watcher.lua:110>

It's similar, but perhaps coincidentally related to the above. Either way it's the watcher receiving a nil filename.

Printing the info before this error occurs reveals:

watcher_cb(1): Git dir update: 'nil' { rename = true }

I don't know what a rename of an empty filename means though. I see #823 is about improving the watcher, perhaps this can be resolved there.

Also, I'm running on FreeBSD, so maybe the event manager behaves differently? I've been seeing this for many weeks and it happens every time I use Git with a file open.

This is my temporary fix: otrho@fa1fd99

This is my temporary fix: otrho@fa1fd99

That fix indicates to me that luv is behaving weirdly. According to https://github.com/luvit/luv/blob/master/docs.md#uvfs_event_startfs_event-path-flags-callback path should always be a string and never nil.

However since it obviously can be nil in some cases, I'd accept this fix in a PR.

I updated to the latest version (which includes #851), but I'm still running into the same error message. Not sure if a similar "catch" statement makes sense in this case; as mentioned above, the cache[bufnr] is already checked for a nil value earlier in the function, so I don't think this has anything to do with libuv returning a nil rather than string.

Ah yes, there's a scheduler call before the access which means the buffer may have detached. So to fix this we just need to do a simple buffer check after the scheduler.

So to fix this we just need to do a simple buffer check after the scheduler.

So basically a copy-paste of this:

gitsigns.nvim/lua/gitsigns/watcher.lua

Lines 60 to 66 in 5d73da7

if not cache[bufnr] then
-- Very occasionally an external git operation may cause the buffer to
-- detach and update the git dir simultaneously. When this happens this
-- handler will trigger but there will be no cache.
dprint('Has detached, aborting')
return
end

Sort of yes.

#854 should address a bunch of latent issues. Let me know if it fixes this one.

Well, I just ran into the issue, updated the plugin, but it still happens. So those fixes didn't change the behavior.

Same line number?

Yep, same exact line numbers. Also verified that the plugin repo actually updated to main as well.

Running into this issue as well as of d195f0c; pops up intermittently when I have a lot of files open. If it's of any relevance I only see this happen when working in a large monorepo.

This happens to me as well together with fugitive:

  • check out a commit in interactive rebase
  • :G show to display the diff
  • open a diff, which opens the a fugitive temp file
  • :Ge to edit the file -> error
