check-webkit-style failed to complain about missing braces

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Evan Martin]

This patch:
https://bugs.webkit.org/show_bug.cgi?id=34186#c1

had this diff:

         ASSERT(U_SUCCESS(error));
+        for (unsigned i = 0; i < normalizedString.length(); ++i)
+            if (Font::treatAsSpace(m_normalizedBuffer[i]))
+                m_normalizedBuffer[i] = ' ';
 

Which I'm informed lacks parens.  But the style bot didn't mind it.

[Evan Martin]

Er, make that: "... which lacks *braces*."

I have a draft patch for this. It works fine on the examples you mentioned previously, but it complains about this:

if (missedCues[i].data()->startTime() < missedCues[i].data()->endTime())
    eventTasks.append(std::make_pair(missedCues[i].data()->endTime(),
                                     missedCues[i].data()));

I'm a bit confused. Is this false positive or not? Should we use braces in this case?

Meanwhile I found the answer here: http://www.webkit.org/coding/coding-style.html#braces-one-line

We don't want foreach here.
