Using the 4.3 war available for download, I attempted to set up my core using the solr.properties file (in anticipation of moving to 5.0). When I start the context, logging shows that the process is falling back to the default solr.xml file (essentially the second bullet does not occur). After digging through the 4_3 branch it looks like solr.properties is not yet part of the library. Am I missing something (I'm able to get the context started using a solr.xml file with "<solr></solr>" as the contents)?
I think you're right about the wiki being inaccurate. Although I probably have enough access to rename the wiki page from 4.3 to 4.4, I don't know how to do it. I have updated the existing page with a note summarizing some of what's below:
The core discovery code is fundamentally broken in 4.3. The code that will be released as part of Solr 4.4 (branch_4x) is VERY different. There will soon be a 4.3.1 release, but due to the massive code changes, the known bugs in core discovery will not be fixed in that release, and there may be bugs that we don't even know about yet.
If you want to experiment with core discovery now, I would recommend that you download the source code or a nightly build of branch_4x, the current stable release branch. This branch is usually free of major showstopper bugs. Not always of course, because it is under active development, but we do try.
If you want something more stable, then use the old-style solr.xml with 4.2.1 or 4.3.x.
The 5.0 release (currently called trunk) is still a long way off. The trunk and branch_4x codebases are currently similar enough that most patches will work on both versions without any manual work at all. This means that almost every new feature gets added to both 4.x and 5.0. Eventually the two branches will diverge to the point where backporting features to 4.x will be extremely hard. That is likely the point where branch_5x will be created and there will be a major effort to release 5.0.
