From 5f866188e029ba68b059a8764833b69cb3dc9d05 Mon Sep 17 00:00:00 2001 From: Liran Cohen Date: Tue, 3 Mar 2026 16:54:38 +0000 Subject: [PATCH 2/3] fix: daemon spawn, nonce replay, and server crash on missing repo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three bugs that prevent push from working: 1. findGitdBin() returned a raw .ts path that spawn() tried to execute directly, failing with EACCES. Now returns { command, prefix } so the daemon is spawned via `bun src/cli/main.ts serve`. 2. createPushAuthenticator() tracked nonces and rejected reuse. Git reuses the same credentials for GET ref-discovery and POST receive-pack within a single push, so every push got a 401 on the second request. Removed nonce tracking — token expiry is sufficient. 3. getRepoContext() called process.exit(1) in a server context, killing the daemon when cloning a nonexistent repo. Now throws instead. --- src/daemon/lifecycle.ts | 24 ++++++++++++++++-------- src/git-server/auth.ts | 23 +++++------------------ tests/daemon-lifecycle.spec.ts | 9 +++++---- tests/hardening.spec.ts | 6 ++++-- 4 files changed, 30 insertions(+), 32 deletions(-) diff --git a/src/daemon/lifecycle.ts b/src/daemon/lifecycle.ts index 6832335..fc5d5a8 100644 --- a/src/daemon/lifecycle.ts +++ b/src/daemon/lifecycle.ts @@ -161,7 +161,7 @@ async function spawnDaemon(password?: string): Promise { env.GITD_PASSWORD = password; } - const child = spawn(gitdBin, ['serve'], { + const child = spawn(gitdBin.command, [...gitdBin.prefix, 'serve'], { detached : true, stdio : ['ignore', logFd, logFd], env, @@ -293,19 +293,27 @@ export function daemonStatus(): DaemonStatus { // Helpers // --------------------------------------------------------------------------- -/** Find the gitd binary path. */ -export function findGitdBin(): string { - // In development: use the source entry point relative to this module. - // This file lives at src/daemon/lifecycle.ts, so ../../cli/main.ts - // resolves to src/cli/main.ts. +/** Resolved gitd binary and how to invoke it. */ +export type GitdBin = { + /** The binary or runtime to spawn. */ + command: string; + /** Arguments to pass before `['serve']` etc. */ + prefix: string[]; +}; + +/** Find the gitd binary path and determine how to invoke it. */ +export function findGitdBin(): GitdBin { + // In development: use bun to run the source entry point. + // This file lives at src/daemon/lifecycle.ts (or dist/esm/daemon/lifecycle.js), + // so we check for the sibling src/cli/main.ts. const thisDir = dirname(fileURLToPath(import.meta.url)); const devPath = join(thisDir, '..', '..', 'src', 'cli', 'main.ts'); if (existsSync(devPath)) { - return devPath; + return { command: 'bun', prefix: [devPath] }; } // When installed: `gitd` should be on PATH. - return 'gitd'; + return { command: 'gitd', prefix: [] }; } function sleep(ms: number): Promise { diff --git a/src/git-server/auth.ts b/src/git-server/auth.ts index 05a5fbc..b3d3f20 100644 --- a/src/git-server/auth.ts +++ b/src/git-server/auth.ts @@ -215,18 +215,6 @@ export function createPushAuthenticator( ): (request: Request, did: string, repo: string) => Promise { const { verifySignature, authorizePush, maxTokenAge = 300 } = options; - // Nonce replay protection: track used nonces with timestamps for TTL eviction. - const usedNonces = new Map(); - const nonceMaxAge = (maxTokenAge + 60) * 1000; // ms — token TTL + clock skew - - /** Evict expired nonces to prevent unbounded growth. */ - function evictExpiredNonces(): void { - const cutoff = Date.now() - nonceMaxAge; - for (const [nonce, ts] of usedNonces) { - if (ts < cutoff) { usedNonces.delete(nonce); } - } - } - return async (request: Request, ownerDid: string, repo: string): Promise => { // Extract HTTP Basic auth credentials. // Username is fixed to "did-auth" (DIDs contain colons, which conflict @@ -291,12 +279,11 @@ export function createPushAuthenticator( return false; } - // Nonce replay protection — reject already-used nonces. - evictExpiredNonces(); - if (usedNonces.has(payload.nonce)) { - return false; - } - usedNonces.set(payload.nonce, Date.now()); + // NOTE: Nonce replay protection is intentionally omitted. + // Git's smart HTTP transport reuses the same credentials for both + // the GET ref discovery and POST receive-pack within a single push. + // Rejecting reused nonces would break every push.
