1662281 - Silence `[... WARN webrender_bindings::bindings] Could not find symbol "gl..." by glcontext` log spam

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Nick Alexander :nalexander [he/him]]

On macOS, with no RUST_LOG or similar in the environment (that I am aware of), local builds produce a ton of log spam, all of the form:

[2020-08-31T22:00:05Z WARN  webrender_bindings::bindings] Could not find symbol "glVertexP2uiv" by glcontext
...

Whatever this is, it probably isn't a warning, since there's no reasonable action to be taken. Can we quiet this down, at least for developer builds?

Attachment: Bug 1662281 - Don't warn when GL symbol lookup fails. We look up symbols for many extensions, for which symbol lookup is expected to fail. r=jrmuizel,sotaro

We can bring this back if we have a way to only print the warning for essential symbols, bug 1322949.
