From 13a81e454a721820b7ab5a4b39ecff2b1eb6fb36 Mon Sep 17 00:00:00 2001 From: Conrad Irwin Date: Wed, 11 Dec 2024 14:05:10 -0700 Subject: [PATCH] Start to split out initialization and registration (#21787) Still TODO: * [x] Factor out `start_language_server` so we can call it on register (instead of on detect language) * [x] Only call register in singleton editors (or when editing/go-to-definition etc. in a multibuffer?) * [x] Refcount on register so we can unregister when no buffer remain * [ ] (maybe) Stop language servers that are no longer needed after some time Release Notes: - Fixed language servers starting when doing project search - Fixed high CPU usage when ignoring warnings in the diagnostics view --------- Co-authored-by: Piotr Osiewicz <24362066+osiewicz@users.noreply.github.com> Co-authored-by: Cole --- crates/assistant/src/assistant_panel.rs | 6 +- crates/collab/src/rpc.rs | 3 + crates/collab/src/tests/editor_tests.rs | 9 +- crates/collab/src/tests/integration_tests.rs | 99 +- .../remote_editing_collaboration_tests.rs | 6 +- crates/editor/src/editor.rs | 57 +- crates/editor/src/editor_tests.rs | 45 +- crates/editor/src/inlay_hint_cache.rs | 1396 +- .../src/extension_store_test.rs | 4 +- crates/language_tools/src/lsp_log_tests.rs | 2 +- crates/multi_buffer/src/multi_buffer.rs | 16 +- crates/project/src/buffer_store.rs | 19 + crates/project/src/lsp_store.rs | 12760 ++++++++-------- crates/project/src/project.rs | 34 + crates/project/src/project_tests.rs | 113 +- crates/project_symbols/src/project_symbols.rs | 2 +- crates/proto/proto/zed.proto | 10 +- crates/proto/src/proto.rs | 3 + .../remote_server/src/remote_editing_tests.rs | 8 +- 19 files changed, 7472 insertions(+), 7120 deletions(-) diff --git a/crates/assistant/src/assistant_panel.rs b/crates/assistant/src/assistant_panel.rs index 109c9c32370cf..21112baa1f263 100644 --- a/crates/assistant/src/assistant_panel.rs +++ b/crates/assistant/src/assistant_panel.rs @@ -5113,9 +5113,11 @@ fn make_lsp_adapter_delegate( return Ok(None::>);
