"At the end of last month's article, I announced that the Apache Group was ready to release the first Beta of Apache 2.0. If you have been watching the news coming from the Apache Group, you have probably noticed that the beta has not been released yet. This month, I will discuss why the first beta was not released, what has changed since last month, and our current plans for the first beta."
"All of the Apache 2.0 alphas have suffered from one problem, mod_include didn't work. Obviously this is a major problem, many web sites rely on Server Side Includes to create dynamic web pages. In Apache 1.3 this module was implemented as a handler, meaning that SSIs had to be stored on disk. With Apache 2.0, it makes more sense to implement mod_include as a filter, this allows SSIs to be implemented as files on disk, the output from CGI scripts, or as the output from any other module. However, re-writing mod_include as a filter turned out to be a non-trivial problem. After weeks of work, mod_include has been completed, and it now works as a filter."
"While waiting for mod_include, we also discovered that piped logs, notably reliable piped logs, had a major problem. We were checking to determine if the pipe between Apache and the logging program was still writable. If not, Apache assumed the logging process had died, and restarted it. The problem is that operating systems will report that the pipe is unwritable in multiple situations, and only one of those is that the process has actually stopped reading. For example, we were seeing Apache stop and restart the logging process if the pipe was full. This means that when the piped log process is at its busiest, Apache was stopping and restarting the logging process."
