From 91d5a0b2c9833055df0d9341522ab96da903c9f2 Mon Sep 17 00:00:00 2001 From: Mohammed Munzir Date: Tue, 20 Oct 2026 18:14:25 +0300 Subject: [PATCH 1/3] build: vendor gpui-pre-linux 0.3.6 unmodified Replace the registry crate through [patch.crates-io] with a byte-for-byte copy so Linux platform fixes can ship before a gpui-pre release carries them. The crate is excluded from the workspace and keeps its upstream layout. --- Cargo.lock | 2 - Cargo.toml | 5 + vendor/README.md | 13 + vendor/gpui-pre-linux/Cargo.toml | 307 ++ vendor/gpui-pre-linux/LICENSE-APACHE | 222 ++ vendor/gpui-pre-linux/src/gpui_linux.rs | 4 + vendor/gpui-pre-linux/src/linux.rs | 60 + vendor/gpui-pre-linux/src/linux/dispatcher.rs | 365 ++ vendor/gpui-pre-linux/src/linux/headless.rs | 4 + .../src/linux/headless/client.rs | 143 + .../src/linux/headless/window.rs | 236 ++ vendor/gpui-pre-linux/src/linux/keyboard.rs | 22 + vendor/gpui-pre-linux/src/linux/platform.rs | 1604 ++++++++ .../src/linux/system_notifications.rs | 154 + .../gpui-pre-linux/src/linux/text_system.rs | 1 + vendor/gpui-pre-linux/src/linux/wayland.rs | 42 + .../src/linux/wayland/client.rs | 3223 +++++++++++++++++ .../src/linux/wayland/clipboard.rs | 263 ++ .../src/linux/wayland/cursor.rs | 152 + .../src/linux/wayland/display.rs | 42 + .../src/linux/wayland/layer_shell.rs | 26 + .../gpui-pre-linux/src/linux/wayland/popup.rs | 38 + .../src/linux/wayland/serial.rs | 126 + .../src/linux/wayland/window.rs | 2332 ++++++++++++ vendor/gpui-pre-linux/src/linux/x11.rs | 12 + vendor/gpui-pre-linux/src/linux/x11/client.rs | 3159 ++++++++++++++++ .../gpui-pre-linux/src/linux/x11/clipboard.rs | 1255 +++++++ .../gpui-pre-linux/src/linux/x11/display.rs | 51 + vendor/gpui-pre-linux/src/linux/x11/event.rs | 154 + vendor/gpui-pre-linux/src/linux/x11/window.rs | 2051 +++++++++++ .../src/linux/x11/xim_handler.rs | 133 + .../src/linux/xdg_desktop_portal.rs | 191 + 32 files changed, 16390 insertions(+), 2 deletions(-) create mode 100644 vendor/README.md create mode 100644 vendor/gpui-pre-linux/Cargo.toml create mode 100644 vendor/gpui-pre-linux/LICENSE-APACHE create mode 100644 vendor/gpui-pre-linux/src/gpui_linux.rs create mode 100644 vendor/gpui-pre-linux/src/linux.rs create mode 100644 vendor/gpui-pre-linux/src/linux/dispatcher.rs create mode 100644 vendor/gpui-pre-linux/src/linux/headless.rs create mode 100644 vendor/gpui-pre-linux/src/linux/headless/client.rs create mode 100644 vendor/gpui-pre-linux/src/linux/headless/window.rs create mode 100644 vendor/gpui-pre-linux/src/linux/keyboard.rs create mode 100644 vendor/gpui-pre-linux/src/linux/platform.rs create mode 100644 vendor/gpui-pre-linux/src/linux/system_notifications.rs create mode 100644 vendor/gpui-pre-linux/src/linux/text_system.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/client.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/clipboard.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/cursor.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/display.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/layer_shell.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/popup.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/serial.rs create mode 100644 vendor/gpui-pre-linux/src/linux/wayland/window.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/client.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/clipboard.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/display.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/event.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/window.rs create mode 100644 vendor/gpui-pre-linux/src/linux/x11/xim_handler.rs create mode 100644 vendor/gpui-pre-linux/src/linux/xdg_desktop_portal.rs diff --git a/Cargo.lock b/Cargo.lock index bbdcaf6ef..36545d642 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3782,8 +3782,6 @@ dependencies = [ [[package]] name = "gpui-pre-linux" version = "0.3.6" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "aab655cda1d6dcd549ac869e8678babc84cf573ab6794a1fe1a39c6c70c60b48" dependencies = [ "accesskit", "accesskit_unix", diff --git a/Cargo.toml b/Cargo.toml index a0d501734..5a9ce9b4d 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,5 +1,7 @@ [workspace] members = ["crates/embed-resource", "crates/herdr-client", "crates/herdr-gpui", "crates/herdr-gpui-launcher", "crates/herdr-protocol"] +# Vendored third-party crates keep their upstream layout and lint baseline. +exclude = ["vendor/gpui-pre-linux"] resolver = "2" [workspace.package] @@ -138,3 +140,6 @@ zeroize = "=1.9.1" # no-op stands in for it.

Bind ext_background_effect_manager_v1 in the vendored gpui-pre-linux and prefer it, keeping org_kde_kwin_blur as the fallback. Its blur region starts empty, unlike KDE's whole-surface default, so it is given the window area GPUI already computes for the opaque region. Clearing the blur or closing the window destroys the effect object, which removes the region on the next commit.
