Question

我们希望使用OpenGrok索引我们（相当大的）git存储库集合，而我无法弄清楚的一件事是如何索引所有分支。从我所看到的，看起来我需要签出我想要索引的每个分支的副本，所以，如果一个存储库有十几个分支，我需要有十几个分支，一个对于每个分支，例如，

git-repo-with-many-branches-master/
git-repo-with-many-branches-branch1/
git-repo-with-many-branches-branch2/
       :
git-repo-with-many-branches-branch12/

这是真的吗？或者有没有办法告诉OpenGrok在创建索引时查看所有分支？

Answer 1

OpenGrok中的其他层设计用于多个不像git一样工作的SCM系统，所以不幸的是，你必须检查你想要索引的每个分支作为一个单独的git存储库： - （

您可以随时提交RFE以支持浏览git存储库中的多个分支。

Answer 2

我为此专门编写了一个脚本：daun。您需要在cron作业中使用daun cli而不是git cli。请注意，在撰写本文时它不支持OpenGrok git历史记录，因为我们只对OpenGrok快速搜索功能感兴趣。我们会将OpenGrok用户指向GitHub / Bitbucket这样的工具，用于基于Web的git历史记录。

Answer 3

这是我为此做的一个bash脚本。它将克隆任何新分支，更新任何现有分支，并删除不再存在的分支。以下是“工作”的说明;您可以选择使事情更安全，但如果您的服务器只能在您的LAN上访问，这就足够了。我有一个cron作业设置，只需在服务器上每30分钟运行一次。要将cron作业设置为以root身份运行，请运行：

sudo crontab -e

然后粘贴这些内容：

*/30 * * * * /usr/local/bin/opengrok_index.sh

然后写下并关闭：

:wq

您需要安装脚本用来输入ssh密钥密码的“expect”。根据您使用的Linux操作系统，这两个命令中的一个将起作用：

sudo yum install expect
sudo apt-get install expect

然后在/usr/local/bin/opengrok_index.sh中创建一个文件：

sudo vi /usr/local/bin/opengrok_index.sh

接下来，粘贴脚本的内容（从这篇文章的底部），并根据您的系统更改顶部的变量。接下来，更改权限，以便只有root可以读取它（它有密码）：

sudo chmod 700 /usr/local/bin/opengrok_index.sh

您可能希望在期望cron作业工作之前，手动测试运行脚本并使其正常工作。这是我为特定设置编写的特定脚本，因此您可能需要输入一些echo语句并进行一些调试以使其正常工作：

sudo /usr/local/bin/opengrok_index.sh

附加说明：

此脚本通过SSH（不是HTTPS）登录到GIT。就这样，你的 GIT_USER必须存在于系统上，并且具有SSH密钥 /home/user/.ssh/id_rsa可以访问GIT仓库。这是标准GIT登录的东西所以我不会在这里讨论它。脚本会提示时输入GIT_USER_SSH_PASSWORD
该脚本将所有文件检出为GIT_USER，因此您可能需要将CHECKOUT_LOCATION“chown”给该用户

脚本：

#!/bin/bash

SUDO_PASSWORD="password"
CHECKOUT_LOCATION="/var/opengrok/src/"
GIT_PROJECT_NAME="Android"
GIT_USER="username"
GIT_USER_SSH_PASSWORD="password"
GIT_URL="yourgit.domain.com"
OPENGROK_BINARY_FILE="/usr/local/opengrok-0.12.1.6/bin/OpenGrok"

# Run command as GIT_USER which has Git access
function runGitCommand {
  git_command="$@"

  expect_command="
    spawn sudo -u $GIT_USER $git_command
    expect {
        \"*password for*\" {
            send \"$SUDO_PASSWORD\"
            send \"\r\"
            exp_continue
        }
        \"*Enter passphrase for key*\" {
            send \"$GIT_USER_SSH_PASSWORD\"
            send \"\r\"
            exp_continue
        }
    }"

Answer 4

我对OpenGrok一无所知，但当然你可以使用Git更改分支：

git checkout master
# do the indexing here
git checkout branch1
# indexing
git checkout branch2
# and so on...

如何在OpenGrok中处理git分支？
