Details

somehow my windows environment got messed up, and I am 100% in the dark on this development environment. Using windows build I used to be able to start the shell and then do my normal hg and mach commands. This worked great until this morning when the shell wouldn't start (bug 1309541). I reverted a windows OS update, now I can get to my cygwin/bash prompt :) once there, I found out that hg was limited (my strip command failed as there were no extensions defined). I fixed this by editing my hgrc file. Outside of that I wanted to run mach, so I tried: mach clobber ./mach clobber both end up with: Could not run mach: No mach source directory found. I am not sure how to self correct here- it is so expensive to start over again in regards to network bandwidth and time.
The "No mach source directory found" error is from `mach` itself. When you run `mach`, it traverses the current working directory, looking for mozinfo.json (objdir) or config.status (topsrcdir). If it can't find those or a "build/mach_bootstrap.py" file at the resolved topsrcdir, you get this error. Assuming your checkout is sane and you are running `./mach`, you should *never* get this failure. Are you sure you were running `./mach` and not `mach` (which may resolve to a random executable in PATH)? Assuming you run `./mach` my best guess is your checkout is incomplete/corrupt. What does `hg status` say? You can "reset" your checkout by doing something like: $ hg up -C null $ hg up central

hg status has 492 files in the ! state, all in the build/ directory. both |mach| and |./mach| fail in the same way. and the: hg up null hg up central fixed my issues. feel free to resolved as worksforme if there is nothing to do to fix this.

Yeah, somehow your working directory got corrupt :/
