Describe the bug

当搜索出大量unlist buffer时，输入会有卡顿。期望unlisted和隐藏的buffer不会导致卡顿

Reproduce the bug

#!/usr/bin/env ruby

contents = "# a very long line, a very long line, a very long line, a very long line, a very long line, a very long line\n"
contents = contents * 9999;
contents << "keyword"
5000.times do |i|
  File.write("#{i}.rb", contents)
end

用上面脚本创建大量文件，然后搜索keyword使得buffer被加载到unlisted buffer里。(ls!会显示，但是ls不会)。之后的输入就会有明显的卡顿感。使用:%bwipe命令清空所有buffer后恢复不再卡顿。（%bdelete没有效果）

如何搜索？

chemzqm commented 3 years ago

应该是你自己 vim 或者机器的问题

如何搜索？

我使用的mhinz/vim-grepper 进行的搜索。我试试用最原始的vim看能不能复现

SolaWing commented 3 years ago

@chemzqm 我创建了一个最小化的vim demo，并装上solargraph插件（其他languageserver应该也能复现）。在创建buffer并在vim通过LoadBuffer加载qlist后，在rb文件insert mode狂打字，可以很明显的看到卡顿。
