rcov 0.3.0: happier Rails (code coverage analysis)
Driven by user feedback, rcov 0.3.0 introduces a number of features that simplify the analysis of Rails applications. Moreover, this is the first time a rcovrt binary for win32 (which makes rcov >100 times faster) is released simultaneously.
The new code coverage analysis mode, --test-unit-only, records exclusively code executed inside Test::Unit::TestCase(s). This allows you to see how much of your code was directly unit-tested, and how much was executed indirectly (e.g. run in the initialization phase or executed by the framework outside the tests). Also, this makes rcov 10-20% faster when analyzing a Rails application like Typo (on my old box, rcov runs its unit tests in 13.5s in normal mode compared to ~11s with --test-unit-only). Not quite as spectacular as the >10000% speed increase from 0.1.0 to 0.2.0 though.
Another important addition is the ability to detect aliased source files: this was very needed to analyze Rails apps, where a file could get loaded under several different names, due to the extensive usage of #require with relative paths.

If you're under win32 and cannot build extensions, you can also get the pre-built rcovrt.so binary. This extension was cross-compiled using mingw; here's more information about how to cross-compile for win32.
- consolidate multiple references to the same underlying .rb file (much needed for Rails)
- consider and/op operators
- honor --no-color in (rich) text mode
- output valid XHTML indices
- many minor bugs squashed
- Tom Dolbilin:
- identified and fixed backslash problem on win32 for generated filenames
- Andrew Kreiling:
- made the index XHTML compliant
- consolidate multiple references to the same underlying .rb file
- Robert Feldt:
- pointed me to dynamic uses of the tracing hooks, provided the inspiration for RCOV__.run_hooked
