 Note that the correct hostname is **`downloads.sourceforge.net`**, not `download.sourceforge.net`, and not an arbitrary mirror.
 
+## Google Open Source

+For software hosted on Google Open Source (i.e., the domain name `*.googlesource.com`), since the tarball provided is dynamically generated and does not have a fixed SHA256 value, you should refer to the last section of this article to obtain the source from the Git tag.

 ## Non-standard Download URLs
 
 Sometimes upstream provides download URLs that do not end with the tarball filename. In such cases, RPM cannot automatically determine the source archive name from the URL.

 ## 奇奇怪怪的 URL
 
 当上游的下载 URL 不以 tarball 名称结尾时，rpm 将无法从源码 URL 中解析出 tarball。一种适用于多种情况的变通方法是构建一个 URL，将 tarball 列在 "URL 片段" 中:
