This patch doesn't look correct.

> Tools/TestResultServer/static-dashboards/flakiness_dashboard.html:1819
>          master = builderMaster(testResults[0].builder);

Did you intend to make the variable master global? Because this patch removed the declaration "var master" (above) this line will create a global variable called master. From looking at the names of other global variables in declared in this file, a global variable should have a "g_" prefix.

> Tools/TestResultServer/static-dashboards/flakiness_dashboard.html:1840
> +    var master;

This variable is unused and masks the global variable of the same name defined in htmlForIndividulTestOnAllBuilders() (above). Hence, the equality check "master == WEBKIT_BUILDER_MASTER" (in the original code; not part of this patch) will always evaluate to false, since |master| === undefined.

Disregard the "This variable is unused" part of this sentence.

Whoops. No. I just missed this. Inlined the variable and added test cases. Thanks for catching this.

Also, I made the postMessage code a little more robust.

Thanks Ojan for updating the patch. I noticed some minor issues.

> Tools/ChangeLog:13
> +        (testHtmlForIndividulTestOnAllBuilders):
> +        (testHtmlForIndividulTestOnAllBuildersWithChrome):

This change log needs to be updated. In particular, these functions have been renamed to testHtmlForIndividualTestOnAllBuilders and testHtmlForIndividualTestOnAllBuildersWithChrome, respectively.

> Tools/TestResultServer/static-dashboards/flakiness_dashboard.html:1855
> +        if (testResults && builderMaster(testResults[0].builder) == WEBKIT_BUILDER_MASTER) {

Can testResults be an empty list? Is checking for isLayoutTestResults() sufficient? Previously we checked for a non-zero value for testResults.length before accessing testResults[0].

As far as I can tell the g_currentState.showChrome won't change inside this loop. And we use the value of g_currentState.showChrome to determine which function to call. I suggest hoisting this code outside of the for-loop and inlining the definition of test such that this for-loop has the form:

var htmlForTestFunction = g_currentState.showChrome ? htmlForIndividualTestOnAllBuildersWithChrome : htmlForIndividualTestOnAllBuilders;
for (var i = 0; i < tests.length; i++)
    testsHTML.push(htmlForTestFunction(tests[i]));

Can we use JSON.stringify rather than building up JSON strings with string concatenation?

Good eye. The old code was wrong. The list cannot be empty. I'll changed the other code to remove the length check.

Good suggestion.

Good idea.
