如何构建一个 git polling build bot? [英] How to build a git polling build bot?

问题描述

基于 cron、bash + make 的脚本(例如，比 Hudson 更小、更不健壮)构建机器人如何轮询 git 存储库并检测它是否应该现在构建 - 例如如果在从远程 git repo 定期拉取时，它已检索到新代码?

How can a little cron, bash + make based script (e.g. much smaller and less robust than, for example, Hudson) build-bot poll a git repo and detect if it should build now - e.g. if in its periodic pull from the remote git repo, it has retrieved new code?

目前，它看起来像这样:

Currently, it looks like this:

git fetch  > build_log.txt 2>&1
if [ $? -eq 0 ]
then
  echo "Fetch from git done";
  git merge FETCH_HEAD >> build_log.txt 2>&1 ;
  if [ $? -eq 0 ]
  then
    echo "Merge via git done"; ...
    # builds unconditionally at the moment
  fi
fi

推荐答案

如果没有获取任何内容，则get fetch"将不输出任何行，因此只需检查 build_log.txt 上的零文件大小:

If nothing was fetched, then "get fetch" will output no lines, so just check for zero filesize on build_log.txt:

git fetch > build_log.txt 2>&1
if [ -s build_log.txt ]
then
   # build
fi
