[usdShade] GetPrimvarNamesMetadataString - only append non-empty string #2131
Conversation
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
Learn more about bidirectional Unicode characters
on some compilers / architectures, if you do:
metadata["primvars] = GetPrimvarNamesMetadataString(...)
...this results in a default / empty string being inserted into
metadata["primvars"] BEFORE GetPrimvarNamesMetadataString is called.
Therefore, we only insert existing non-empty strings into the list that
GetPrimvarNamesMetadataString builds. (And it's a good check in general
anyway.)
This fixes a test failure in testUsdShadeShaderDef on linux aarch64
using gcc 7.5.
