Bug 65806 – Potential Leaks - RetainPtr<> over retaining Create'd objects

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Joseph Pecoraro]

shell> cd Source/
shell> ack 'Retain.*?=.*?Create'

    WebCore/platform/network/mac/NetworkStateNotifierMac.cpp
    108:    RetainPtr<CFRunLoopSourceRef> configSource = SCDynamicStoreCreateRunLoopSource(0, m_store.get(), 0);
    
    WebCore/plugins/mac/PluginPackageMac.cpp
    123:        WTF::RetainPtr<CFStringRef> str = CFStringCreateWithPascalString(0, p, encoding);
    143:        WTF::RetainPtr<CFStringRef> path = CFStringCreateWithFormat(0, 0, CFSTR("%@/Library/Preferences/%@"), homeDir.get(), fileName.get());
    
    WebKit/mac/WebView/WebView.mm
    4215:    RetainPtr<CFMutableSetRef> visitedViews = CFSetCreateMutable(0, 0, 0);

The first looks harmless, the plugin ones look like it could be bad in encountered (in a loop),
and the WebView one looks straightforward if ever encountered.

Each of these looks like they should be an Adopt after reading
the immediately surrounding code.

Did you do the same grep for Copy?

Yep that turned up both of these:
<http://webkit.org/b/65789> Leak in CFNetwork Loader RetainPtr<> should Adopt a Copy allocation
<http://webkit.org/b/65790> [QT] Possible Leaks WKRetainPtr<> should Adopt allocated Copy

Thanks!
