c++ - APR(Apache 可移植运行时)1.3 和 0.9 之间有什么区别？

Question

我刚刚开始使用 APR，似乎同时开发了两个受支持的版本:http://apr.apache.org/

文档没有解释 1.3.x 和 0.9.x 之间的区别...任何人都可以阐明这个问题吗？或者简而言之，我应该使用哪个？

Answer 1

参见 http://www.apache.org/dist/apr/Announcement0.9.html :

This version of APR is principally a bug fix release, and is provided only for users requiring APR 0.9 compatibility. Most developers are encouraged to adopt the latest APR 1.x version to ensure the most comprehensive support and access to the latest features and enhancements.

For example, the Apache HTTP Server Project's httpd 2.0 release uses APR 0.9 for binary compatibility, while later httpd 2.2 releases require APR 1.2 for better support and additional features.
