Hi Felix, Good point. I'll update the patch.
Thanks, Bob -----Original Message----- From: Felix Polyudov [mailto:fel...@ami.com] Sent: Tuesday, February 19, 2019 12:57 AM To: Feng, Bob C <bob.c.f...@intel.com>; edk2-devel@lists.01.org Cc: Gao, Liming <liming....@intel.com> Subject: RE: [edk2] [Patch] BaseTools: Correct the value assignment for StructurePcd Bob, I think silent trimming of input data is not a good idea. The build tool should either report an error (my preference) or a warning that DSC or DEC input value is too long. -----Original Message----- From: edk2-devel [mailto:edk2-devel-boun...@lists.01.org] On Behalf Of Feng, Bob C Sent: Saturday, February 16, 2019 12:55 AM To: edk2-devel@lists.01.org Cc: Liming Gao Subject: [edk2] [Patch] BaseTools: Correct the value assignment for StructurePcd This patch is to fix the code bug in StructurePcd overall value assignment logic. If a Pcd Array size is fixed but the size of actual value in Dsc or Dec is bigger than the Pcd array size, the tool only copy the data as same as that Pcd Array size.
