Bug 138878 – The buildbot dashboard should be compatible with buildbot-0.8.9

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Dana Burkart]

The dashboard should be compatible with 0.8.9 as well as older versions of buildbot to support both internal and open source infrastructure. Specifically, the logic for retrieving revisions from the buildbot instance is broken when used against buildbot-0.8.9.

This doesn't really describe the issue since the dashboard was already compatible with v0.8.9. This is teaching it to cope with the fact that different masters may have different names for the codebases.

This is no longer modified in your patch.

> +        (parseRevisionProperty): Changed.

Needs a description of what's changed and why.

> Tools/BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Scripts/BuildbotIteration.js:104
> +    if (typeof value === "object") {

Shouldn't this check be: if (isMultiCodebaseGotRevisionProperty(property)) {

> +        }

This could be:
value = value[key] || value[fallbackKey];

Or if you want to be paranoid about falsey values:

value = (key in value) ? value[key] : value[fallbackKey];

The braces are not necessary around the body of this if statement since it's only a single line.
