Re: [edk2-devel] [PATCH v2] BaseTools/Python: sys.exit(1) when error occurred

["Bob Feng" <bob.c.feng@intel.com>]

Irene,

This patch looks good. For the subject, I think it's that the build will exit with 1 when the AutoGen error occurred.
Would you update the subject to make it more clear?

With the subject update,

Thanks,
Bob

Subject: [edk2-devel] [PATCH v2] BaseTools/Python: sys.exit(1) when error occurred

From: Irene Park <ipark@nvidia.com>

AutoGen manager/workers halt the progress when an error occurs but doesn't propagate the error code to main and makes main sys.exit(0) and gets the build system unable to catch the occurrence of an error.
This change informs main with an error when a progress is halted and helps main sys.exit(1).
