From 68fbf48733562c84b65e113d841a81641996b872 Mon Sep 17 00:00:00 2001 From: "Marty (Clawdbot)" Date: Wed, 25 Mar 2026 17:42:18 -0500 Subject: [PATCH 1/2] fix: revert keychain stdin approach, fix login prompt (Node 24) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit macOS security command does NOT support reading -w from stdin — it opens /dev/tty and prompts interactively, which broke delega login completely. Revert to passing key via argv (brief exposure, only reliable method without native bindings). Also replace PassThrough stream approach for password masking with simpler terminal:false readline that works on Node 24 without echoing the prompt multiple times. --- src/commands/login.ts | 58 +++++++++++++++++++++---------------------- src/secret-store.ts | 9 ++++--- 2 files changed, 33 insertions(+), 34 deletions(-) diff --git a/src/commands/login.ts b/src/commands/login.ts index fd0ce07..44567dc 100644 --- a/src/commands/login.ts +++ b/src/commands/login.ts @@ -15,42 +15,40 @@ interface MeResponse { } async function promptSecret(question: string): Promise { - // Wrap process.stdout so we can mute the echoed password while keeping - // all EventEmitter methods (on, removeListener, etc.) that Node's readline - // expects.
