git-receive-pack may invoke hook with CWD inside .git/, where 'git rev-parse --show-toplevel' errors with 'must be run in a work tree'. Use $(dirname $0) instead.

# Post-receive hook: push 后自动 build + start
|
||
#
|
||
# 触发场景：
|
||
# - 非 bare repo + receive.denyCurrentBranch=updateInstead：本地推送自动部署
|
||
#
|
||
# 用途：执行 package.json 中的 `build` + `start` 脚本
|
||
# - 实际调用 `pnpm run build`（输出丢，仅记退出码）
|
||
# - 再后台启 `pnpm run start`（nohup，输出丢，hook 立即返回）
|
||
#
|
||
# 设计：逻辑块**封**装为独立函数，main 调**度**（shell 风格）
|
||
# - **全**局变量：LOG_FILE（在 init_log_file **里**定**义**）、CURRENT_BRANCH
|
||
# - **函**数**间**通过 `$LOG_FILE` / `$BUILD_EXIT` 通信
|
||
# - **不**用 set -e —— 各步**自**己处理错**误**（env 不**存**在 / build 失败 / 旧**进**程**不**存**在）→ 让 deploy 错**误****不**挡 git push
|
||
#
|
||
# 关键前置（**解**决 push 后 hook **不**触**发** + pnpm **找**不**到**）：
|
||
# 1) cd 到 repo **顶**层 —— git-receive-pack 调 hook 时 CWD **未**必 = repo 顶
|
||
# 2) 加**载** nvm —— 非交互 shell **不**会 source .bashrc，pnpm **不**在 PATH
|
||
# 3) **验**证 PATH —— 写日**志**确认 pnpm 可**用**（**不**可用则 build **必**失**败**）
|
||
|
||
# ---- 前置：切到 repo 顶 + 加 pnpm 到 PATH ----
|
||
# 重要：不能**用** `git rev-parse --show-toplevel` 获**取** repo **顶**层
|
||
# —— git-receive-pack 调 hook 时 CWD **可**能是 `.git/` 内**部**，
|
||
# 这种情况下 `--show-toplevel` **报**错 `must be run in a work tree`。
|
||
# 解**法**：**直**接**根**据 hook **本**身路径推**算** repo **顶**层。
