Bug 186369 – Add logging around internalError(const URL&)

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Keith Rollin]

There are times when we receive bug reports where the user says that they are simply shown a page saying an internal error occurred. To help understand the circumstances of that error, add some logging to internalError() in WebErrors.cpp. This logging logs at the Error level that internalError() was called and then logs a backtrace.

Looks good! I suggest the modern C++ loop.

Could this be a modern C++ loop?

for (auto stackFrame : stackTrace->stack()) {
   ...

I spoke with Keith in person, and realized that we need the index for logging. So never mind!
