From 18a5139219697bfe1ad073f45c96c9fb381f3baf Mon Sep 17 00:00:00 2001 From: Matias Palma Date: Mon, 20 Apr 2026 22:28:28 -0400 Subject: [PATCH] improvements: parallelize refreshGit sub-calls and gate polling on focus MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit refreshGit awaited four independent git invocations in sequence (get_git_status, get_git_branches, git_log, git_stash_list). Each spawns its own backend `git` child process, so the chain took roughly the sum of the four call latencies — ~150-400 ms per 5 s cycle on realistic repos. Running them concurrently drops that to roughly the max of any single call. Changes: - Use Promise.allSettled to dispatch the four sub-queries in parallel. A failure in any one no longer aborts the rest (git_log on a repo with zero commits used to throw and silently drop status parsing mid-flight; now each result is handled independently). - The "dubious ownership" detection and the no-repo fallback still key off the get_git_status result; the other three just degrade to empty arrays if they fail. - Tighten the interval guard: poll only when the window is visible AND document.hasFocus() is true. A visible-but-unfocused window (user typing in the browser) was still costing a full git refresh every 5 s, which dominated idle CPU on battery. - Add a focus listener that snaps back to a fresh refresh as soon as the user returns, instead of displaying up-to-5-s-stale data until the next tick. --- .../GitExplorerComponent.tsx | 132 ++++++++++++------ 1 file changed, 89 insertions(+), 43 deletions(-) diff --git a/apps/desktop/src/addons/builtin.git-explorer/GitExplorerComponent.tsx b/apps/desktop/src/addons/builtin.git-explorer/GitExplorerComponent.tsx index 8e13e851..48103453 100644 --- a/apps/desktop/src/addons/builtin.git-explorer/GitExplorerComponent.tsx +++ b/apps/desktop/src/addons/builtin.git-explorer/GitExplorerComponent.tsx @@ -187,46 +187,24 @@ const GitExplorerComponent: React.FC = () => { // Git const refreshGit = useCallback(async () => { if (!rootPath) return; - try { - const status = await invoke("get_git_status", { path: rootPath }, { silent: true }); - setIsGitRepo(true); - const lines = status.split("\n").filter((l: string) => l.trim()); - // Porcelain v1: XY filename - // X = staged status, Y = unstaged status - const staged: GitFileChange[] = []; - const unstaged: GitFileChange[] = []; - let conflicts = false; - for (const l of lines) { - const x = l[0]; // staged - const y = l[1]; // unstaged - const file = l.substring(3).trim(); - // Unmerged/conflict codes per porcelain v1: DD AU UD UA DU AA UU. - if ((x === "U" || y === "U") || (x === "A" && y === "A") || (x === "D" && y === "D")) { - conflicts = true; - } - if (x !== " " && x !== "?") staged.push({ status: x, file }); - if (y !== " " && y !== "?") unstaged.push({ status: y, file }); - // Untracked files (??) go to unstaged - if (x === "?" && y === "?") unstaged.push({ status: "??", file }); - } - setHasConflicts(conflicts); - setStagedChanges(staged); - setGitChanges(unstaged); - const payload = await invoke("get_git_branches", { path: rootPath }); - const branchList = Array.isArray(payload?.branches) ? payload.branches : []; - setBranches(branchList); - setCurrentBranch(payload?.current ??
