Will become really realistic once bug 743753 is resolved. Would be very helpful. Assumption here is that the infolog is always empty when there is no particular problem i.e. we don't have stupid compilers that write "Success!!!11!" to it.
Created attachment 626806 [details] [diff] [review] report shader/program infologs as warnings Did some renaming of the new variable and constant introduced in bug 743753. See the comment about how in principle we can't get the shader infologs before glLinkProgram has been called. I wanted to have only one implementation of getting a shader/program's infolog, as that is a bit nontrivial (a shader infolog may come either from ANGLE or from the driver). Unfortunately GetShaderInfoLog converts to UTF16 which is useless for us here as JS warnings are 8bit strings. So I added overloads of Get{Shader,Program}InfoLog not doing the conversion. When a shader infolog has been reported, we don't report the program infolog as this is then, in most cases, just a less helpful duplicate of the information already given in the shader infolog.

I don't think so: this WebGLProgram::UpdateInfo() is called upon program linking, this "program exceeds MAX_VERTEX_ATTRIBS" should simply be a program linking error, and program linking errors aren't GL errors.
