git rev-parse——short HEAD没有得到最新的提交 - git rev-parse --short HEAD doesn't get latest commit

嘿，我是这样使用post钩子的:

<?php
file_put_contents('deploy.log', serialize($_POST['payload']), FILE_APPEND);
$repo_dir = '/home/admin/web/website/repo-fullstack.git';
$web_root_dir = '/home/admin/web/website/public_html';
// Full path to git binary is required if git is not in your PHP user's path. Otherwise just use 'git'.
$git_bin_path = 'git';
$update = false;
// Parse data from Bitbucket hook payload
$payload = json_decode($_POST['payload']);
if (empty($payload->commits)){
  // When merging and pushing to bitbucket, the commits array will be empty.
  // In this case there is no way to know what branch was pushed to, so we will do an update.
  $update = true;
} else {
  foreach ($payload->commits as $commit) {
    $branch = $commit->branch;
    if ($branch === 'production' || isset($commit->branches) && in_array('production', $commit->branches)) {
      $update = true;
      break;
    }
  }
}
if ($update) {
  // Do a git checkout to the web root
  exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' fetch');
  exec('cd ' . $repo_dir . ' && GIT_WORK_TREE=' . $web_root_dir . ' ' . $git_bin_path  . ' checkout -f');
  // Log the deployment
  $commit_hash = shell_exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' rev-parse --short HEAD');
  file_put_contents('deploy.log', date('m/d/Y h:i:s a') . " Deployed branch: " .  $branch . " Commit: " . $commit_hash . "'n", FILE_APPEND);
}
?>

问题是POST钩子得到一个旧的提交，而没有得到最近的提交。我注意到，即使作为ROOT用户。我运行命令git rev-parse——short HEAD，它也会得到旧的提交。所以这绝对不是权限问题。

为什么这个命令不能工作?我只是不明白为什么它得到一个旧的提交。

编辑:如果你想知道的是，最奇怪的问题是，它得到了POST钩子的正确描述。只是没有正确提交。这是什么鬼?

这个脚本有几个问题:

$branch = $commit->branch;

用

代替

$branch = $payload->repository->default_branch

它执行git取回操作，但是你需要git拉取操作，所以在取回

之后添加这个

exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' pull');

我还遇到了从repo中删除的文件仍然存在的问题。要解决这个问题，在git checkout后添加一个git clean，如下所示:

exec('GIT_WORK_TREE=' . $web_root_dir . ' ' . $git_bin_path  . ' clean -fdx');

整个东西看起来像这样，我还添加了一个漂亮的邮件功能:

<?php
$repo_dir = '/srv/users/YOURUSER/gitrepo/APPLICATIONAME';
$web_root_dir = '/srv/users/YOURUSER/apps/APPLICATIONAME/public';
// Full path to git binary is required if git is not in your PHP user's path. Otherwise just use 'git'.
$git_bin_path = 'git';
// Parse data from Github hook payload
$payload = json_decode($_POST['payload']);
$empty = false;
$update = false;
if (empty($payload->commits)){
  // When merging and pushing to bitbucket, the commits array will be empty.
  // In this case there is no way to know what branch was pushed to, so we will do an update.
  $empty = true;
  $update = true;
} else {
    $branch = $payload->repository->default_branch;
    $message = $payload->head_commit->message;
    if ($branch === 'master' ) {
      $update = true;
    }
}
if ($update) {
  // Do a git checkout to the web root
  exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' fetch');
  exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' pull');
  exec('cd ' . $repo_dir . ' &&  GIT_WORK_TREE=' . $web_root_dir . ' ' . $git_bin_path  . ' checkout -f');
  exec('cd ' . $repo_dir . ' &&  GIT_WORK_TREE=' . $web_root_dir . ' ' . $git_bin_path  . ' clean -fdx');
  // Log the deployment
  $commit_hash = shell_exec('cd ' . $repo_dir . ' && ' . $git_bin_path  . ' rev-parse --short HEAD');
  file_put_contents('.deploy.log', date('Y-m-d H:i:s') . "  Github -- " .  $message   . " HASH: " . $commit_hash . "'n", FILE_APPEND);
    // prepare and send the notification email
    $headers = "From: github@YOURDOMAIN.COM'r'n";
    $headers .= 'CC: ' . $payload->pusher->email . "'r'n";

    $headers .= "Content-Type: text/html; charset=ISO-8859-1'r'n";
