What did you do?

I haven't found any solid pattern yet that evidences why it is happening, but I have a vague feeling that it could be caused by any condition when code actions are requested. I had to disable the plugin `https://github.com/kosayoda/nvim-lightbulb' (basically, it shows a lightbulb whenever a code action is available at the current cursor position) because it was causing such anomaly happened more frequently.

Also, I have configured an autocommand that execute the code action organize imports each time the file is saved. This action has been always executed when the anomaly comes up, but it doesn't mean the anomaly happens every time the action is executed.

 vim.api.nvim_create_autocmd('BufWritePre', {
                        group = vim.api.nvim_create_augroup( 'GoFormatting', { clear = true }
                        ),
                        pattern = '*.go',
                        callback = function()
                            local params = vim.lsp.util.make_range_params()
                            params.context =
                                { only = { 'source.organizeImports' } }
                            local result = vim.lsp.buf_request_sync(
                                0,
                                'textDocument/codeAction',
                                params,
                                2000
                            )
                            for _, res in pairs(result or {}) do
                                for _, r in pairs(res.result or {}) do
                                    if r.edit then
                                        vim.lsp.util.apply_workspace_edit(
                                            r.edit,
                                            'utf-16'
                                        )
                                    else
                                        vim.lsp.buf.execute_command(r.command)
                                    end
                                end
                            end

                            vim.lsp.buf.format()
                        end,
                    })

What did you expect to see?

The server gopls should send back a response for every method requested by the client.

What did you see instead?

When it happens, completions|diagnostics|code actions stop working for a while (30 seconds or so, and sometimes, even minutes). The editor shows up the following message Server for client 'gopls' not yet ready!

@dppascual are you definitely observing this with gopls@v0.13.1? That release specifically fixed several root causes that could lead to slow code actions.

The only remaining cause of such behavior is the goimports cache (#59216), but that should be relatively rare. Are you observing this a lot?

Server for client 'gopls' not yet ready!

Do you know if this message is only shown by neovim during initialization? That could indicate a gopls crash followed by a reinitialization.

[dppascual]

@dppascual are you definitely observing this with gopls@v0.13.1? That release specifically fixed several root causes that could lead to slow code actions.

Yes, if you observe the path of the gopls printed out in the log, it points to gopls@v0.13.1

The only remaining cause of such behavior is the goimports cache (#59216), but that should be relatively rare. Are you observing this a lot?

The last working day it happened to me about three times.

Server for client 'gopls' not yet ready!

Do you know if this message is only shown by neovim during initialization? That could indicate a gopls crash followed by a reinitialization.

No, it is shown when I request a code action for organising imports or filling up a new struct, among others.

@findleyr Let me continue digging down into such problem and collecting more info since the gopls is initialized until the errors comes up again. The size of the log could be huge but it will contain the whole trace and help us to identify what's going on.

[dppascual]

@findleyr 30 minutes after gopls is initialized, neovim reports the same error upon executing a code action. Also, I cannot get info from any object neither completion popup is shown. I've attached the log.

lsp.log

[findleyr]

Yes, if you observe the path of the gopls printed out in the log, it points to gopls@v0.13.1

@dppascual sorry for not being clear. I did observe that, but wondered if perhaps you were reporting on issues observed in the past, before the update. Thanks for clarifying.

I've attached the log.

Thank you! We will take a look.

[findleyr]

Sorry, have been backlogged with work. Finally got a chance to dig into this today. Here's a critical section of the logs:

In summary:

• exporter_test.go is changed, presumably in a way that invalidates metadata
• a bunch of requests are canceled, presumably from an early version
• two goroutines try to reload it using go/packages (Load #2 and #4, presumably #3 was cancelled). These are probably (1) diagnosing the change and (2) computing semantic tokens
• after 20s, both loads return.
• semantic tokens are quickly computed for the loaded package

Based on this, I suspect:

1. Some sort of starvation/deadlock during loading... but before load results are returned all the locks are very short lived (there is a longer lived lock to apply the results of loading).
2. Some sort of starvation in the Go command when two loads of the same file occur simultaneously.
3. Some sort of long-lived lock on the previous snapshot preventing it from being cloned.

The 20s interval is suspicious: if we can figure out where that delay/timeout is coming from, it may lead us to the root cause. Of course, it may be coincidental.

@dppascual something you can do to help us narrow this down is the following: start gopls with -debug=localhost:6060 and then visit http://localhost:6060/trace/ following a freeze. There, you should be able to see fine-grained summaries of recent gopls operations. You can also start the debug server dynamically by running Go: Start language server's maintainer interface from the VS Code command palette. If you look through the longest operations, are there some that stick out as taking 20s+? I'd particularly be interested in the longest cache.snapshot.load.

Putting this in the v0.14.0 milestone as it would be good to track this down ASAP. With that said, I don't currently have ideas how to proceed. I don't experience this in my day-to-day development.

From the logs, there definitely appears to be a bug somewhere, but we need more information to track it down.

[dppascual]

@findleyr I've been coding the last two weeks against the latest version of gopls (0.13.2) and I haven't experienced any latency problem. Also I enabled the plugin that was causing the error to appear most frequently but the issue is not reproduced, the server responds in a reasonable time.

Looking at the changes of the latest version of gopls, it is a minor version that applies a concrete bugfix so it should not be related to the mentioned problem. It happened to me with the previous version (0.13.1) but I've not tested such version again after updating to the latest one. I propose to keep this issue open until the next version is released and if the error comes up, I will bring it here with more info.

[dppascual]

hey @findleyr, during the last working day I started to observe that gopls became unresponsive. As you mentioned in your last comment, I have been working with gopls in debug mode since there and the following screenshots show that there are multiple operations stick out as taking more than 20s.

On the other side, I want to mention two other issues non related to this one:

• The first one is the autocomplete operation, it sometimes takes several seconds to show a pop up with the exported values of the recently imported package . It makes coding not very smooth (I have already seen in the backlog a couple of issues that make a mention of it)
• The second one is the diagnostic operation, it usually takes seconds to refresh the UI interface when the error was already fixed. I don't know if the problem comes from the neovim or lsp side. I'm thinking of updating diagnostics only on save because it leads to confusion when coding.

Just mentioning them here because the attached report can shed some light. Let me know if you need more info to track it down.

[findleyr]

Thanks @dppascual

The autocomplete problem is (I believe) understood, and I have fixes on the way (#62665).

I'll highlight one thing that may be related: 1m49s for source.AllImportsFixes. That indicates an enormous time spent in goimports -- longer than I've seen before. Other metrics look similarly unhappy: 30s to run the Go command?!

Could you run gopls stats from your workspace root, and report the result (feel free to prune anything you are uncomfortable sharing)? This will help us get a sense of the size of your workspace.
