Details

Earlier today I updated my (roughly 2 months old) mozilla checkout to the latest trunk revision and tried to build. It failed, with these errors: No rule to make target '../../../xpcom/idl-parser/xpidllex.py' needed by ['<command-line>', '../../../xpcom/idl-parser/xpidllex.py'] No rule to make target '../../../xpcom/idl-parser/xpidlyacc.py' needed by ['<command-line>', '../../../xpcom/idl-parser/xpidlyacc.py'] I did some searching and experimenting and couldn't make any sense of it, but I did see some vaguely related things talking about mozilla-build, so I updated to the latest mozilla-build, and that fixed it. This makes sense because my copy of mozilla-build was installed at least a year ago. It seems like what should have happened here is that attempting to build Firefox with an outdated version of mozilla-build should have thrown up an error ("your mozilla-build is too old") and aborted, or even automatically fetched the newest mozilla-build.
Sometimes you will need to "clobber" your build directory, this was one of those cases. I presume you have your tree underneath the mozilla-build directory, mozilla-build deletes its whole directory tree when re-installing.

Clobbering my build directory has nothing to do with this. My build directory is separate (/c/mozilla/ff-debug) from my mozilla-build directory (/c/mozilla-build/) and the first failed build was kicked off with an empty ff-debug directory.

And yet this was also due to files getting hung around in the source tree due to a build system bug, and it confused the build system I still build fine with old mozbuild, fwiw.
What files in the source tree? How do you explain that those files are gone? All I did was run the new mozbuild installer. No changes were made to my source tree between the failed build and the working build.
I wants to work on this bug. I also have prerequisite knowledge of Html , Css and Javascript.
