- fix http://bugzilla.opendarwin.org/show_bug.cgi?id=7681 memory leak in the plug-in tests * DumpRenderTree/TestNetscapePlugIn.subproj/main.c: (NPP_Destroy): Added code to release the plug-in object. This is the leak fix. (NPP_SetWindow): Remove unneeded code to store the window pointer. * DumpRenderTree/TestNetscapePlugIn.subproj/PluginObject.c: Moved the browser global in here since it's declared in this file's header. Changed the code to set up the pluginClass structure to not use function pointer casts. Those are dangerous because they can hide many types of mismatch. And indeed when I did this I discovered that many functions were missing their boolean return values or had parameter declarations with the wrong types. (pluginGetProperty): Use STRINGZ_TO_NPVARIANT macro for greater simplicity and clarity. Added boolean return value: return true when successful and false when not. (pluginSetProperty): Added boolean return value, return false since we have no properties we can set. (pluginInvoke): Added boolean return value. Return true when successful and false when not. Use NPVARIANT macros where appropriate. Added a missing release for the return value from calling the browser. Changed code to put the strings in malloc buffers instead of relying on GCC's extension that allows variable-sized arrays on the stack. (pluginInvokeDefault): Added boolean return value, return false since we have no default function to call. (pluginInvalidate): Added missing parameter. Removed comment. (pluginAllocate): Removed unneeded cast. This is C code, not C++, so you don't have to cast the result of malloc. (pluginDeallocate): Removed uneeded cast. * DumpRenderTree/TestNetscapePlugIn.subproj/PluginObject.h: Removed some unneeded includes. Changed our PluginObject to use NPObject instead of re-declaring fields that match NPObject's fields. Removed unused NPWindow pointer. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@13233 268f45cc-cd09-0410-ab3c-d52691b4dbfc
