如何处理OpenGrok中的Git分支？

Question

我们想使用OpenGrok索引（相当大的）GIT存储库，而我无法确定的一件事是如何为所有分支索引。从我的看来，我似乎需要拥有要索引的每个分支的签出副本，因此，如果一个存储库有十二个分支，我需要有十二份副本，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/

真的是真的吗？还是有办法告诉OpenGrok看 全部 创建其索引时的分支机构？

Answer 1

OpenGrok中的其他层旨在在多个不起作用的SCM系统上工作，因此，不幸的是，您必须查看每个要索引的分支作为单独的git存储库：--(

您始终可以向RFE提交支持，以支持GIT存储库中的多个分支。

Answer 2

我为此目的编写了一个脚本： daun. 。您将需要使用 daun CLI而不是 git CLI在您的Cron工作中。请注意，它在写作时不支持OpenGrok Git历史记录，因为我们只对OpenGrok快速搜索功能感兴趣。我们将我们的OpenGrok用户将基于Web的GIT历史记录的GitHub/Bitbucket等工具指向。

这是我写的一个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。这是“工作”的说明；您可以选择使事情变得更安全，但是如果您的服务器仅在LAN上访问，则足够好。我有一个CRON作业设置，只需在服务器上每30分钟运行一次。要设置Cron作业以作为root运行，请运行：

sudo crontab -e

然后粘贴到这些内容中：

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

然后写下并关闭：

:wq

您将需要安装脚本使用的“期望”来输入SSH键的密码。这两个命令之一将根据您使用的Linux OS来工作：

sudo yum install expect
sudo apt-get install expect

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

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

接下来，粘贴在脚本的内容（从本文的底部）粘贴，并根据您的系统更改顶部的变量。接下来，更改权限，以便只能读取它（其中包含密码）：

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

您可能想手动测试运行脚本并使其正常工作，然后才能期望Cron作业工作。这是我为我的特定设置编写的一个特定脚本，因此您可能需要提出一些回声语句，并进行一些调试以使其正常工作：

sudo /usr/local/bin/opengrok_index.sh

补充说明：

• 该脚本通过SSH（而非HTTPS）登录到GIT中。因此，您的git_user必须存在于系统上，并且在/home/user/.ssh/id_rsa下具有一个可以访问GIT存储库的SSH键。这是标准的git登录内容，所以我不会在这里浏览它。脚本将在提示时输入git_user_ssh_password
• 该脚本将所有文件查看为git_user，因此您可能需要将Checkout_location“ Chown”为该用户

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
        }
    }"

  command_result=$(expect -c "$expect_command" || exit 1)
}

我对OpenGrok一无所知，但是您当然可以使用git更改分支：

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