Description

2 years ago
If one builds without setting MOZ_OBJDIR and then again with MOZ_OBJDIR set, mach fails to run tests, and seems generally confused.

Steps to reproduce:

1) perform an "in place" build via './mach build' (MOZ_OBJDIR is not set)
2) set MOZ_OBJDIR to another location in mozconfig
3) perform another build via './mach build'
4) attempt to run mochitests via './mach mochitests'

Expected result:
The mochitests run

Actual result:
A mach trace (see below)

Additional possibly related failures:
* I have seen but not captured other errors where tests were not able to find something/something/XPCshell.ini which may have been related.
* Builds were completing but the binary would not be in the expected place in MOZ_OBJDIR (if it was placed anywhere)

Workaround:
Unsetting the MOZ_OBJDIR, clobbering via './mach clobber' and resetting seems to fix things.

Error running mach:

    ['mochitest']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:
