Force Write is ignored if LSP is blocking writes.

[hakan-demirli]

Summary

I cant force write :w! if the LSP is blocking writes.

Reproduction Steps

1. Add this Java config to languages.toml:

[[language]]
name = "java"
language-servers =[
  "jdtls",
]
auto-format = true

2. Open a big java file.
3. Ensure the LSP is working.
4. Start doing rapid modifications and saves as fast as possible.
5. Observe after some time saving is not performed ([+] symbol is still on the buffer and file on the disk is not updated)
6. Quickly try force write: :w!
7. File is still not saved.
8. File will be saved after some time when the LSP catches up to requests.

Workaround:

• :lsp-restart
• :w!

EMPTY. No crash/error happens since I assume this is an expected behavior.

This is the intended behavior: force write will attempt to use LSP formatting if available and that can take a while if the language server is being slow. Forcing a write will create parent directories if they don't already exist and will overwrite files that were modified externally. For a situation like this you would instead want a flag for :w or :w! that would skip formatting (this doesn't exist yet) or you can use :set auto-format false.

jdtls is slower than my grandma even if you manually :format once in a while. I have solved this issue by using an external formatter.

google-java-format takes half a second but its still miles better than jdtls.

[[language]]
name = "java"
language-servers =[ "jdtls" ]
formatter = { command = "google-java-format", args = ["-"] }
auto-format = true
