<pre>Web Inspector: Remove recompileAllJSFunctions timer in ScriptDebugServer
https://bugs.webkit.org/show_bug.cgi?id=127409
Reviewed by Timothy Hatcher.
* bindings/js/ScriptDebugServer.h:
* bindings/js/ScriptDebugServer.cpp:
(WebCore::ScriptDebugServer::ScriptDebugServer):
Remove m_recompileTimer and the recompile soon function.
We can just recompile immediately in all existing cases.
* bindings/js/PageScriptDebugServer.h:
* bindings/js/PageScriptDebugServer.cpp:
(WebCore::PageScriptDebugServer::addListener):
(WebCore::PageScriptDebugServer::removeListener):
(WebCore::PageScriptDebugServer::recompileAllJSFunctions):
(WebCore::PageScriptDebugServer::didAddFirstListener):
(WebCore::PageScriptDebugServer::didRemoveLastListener):
Add a "didAddFirstListener" to match "didRemoveLastListener".
Only recompile functions when we attach the debugger and when
we detach the last listener.
* bindings/js/WorkerScriptDebugServer.cpp:
(WebCore::WorkerScriptDebugServer::addListener):
(WebCore::WorkerScriptDebugServer::removeListener):
(WebCore::WorkerScriptDebugServer::recompileAllJSFunctions):
Same thing. Also rearrange the functions to read better.
* inspector/InspectorProfilerAgent.cpp:
Use the direct recompile function instead of the removed "soon" version.</pre>
