2014-08-19Fix bug in CPDF_PageContentGenerate constructor and destructorBo Xu
m_pageObjects never gets initialize, thus making CPDF_PageContentGenerate::GenerateContent() doing nothing. Since the CPFD_PageObject are owned by m_pPage, no need to release them in the destructor.

space in CPDF_ColorSpace::Load The test file defines a wrong color space object (7 0 obj). In the content of 7 0 obj, the reserved obj (0 0 R) is used. The process of loading color space returns NULL when the reserved obj (0 0 R) is found. For the error color space, it only needs to return NULL when an error is detected.

2014-08-13Add FX_OVERRIDE and use it for virtual functions of FX_FINAL classes.Tom Sepez
Should there be cases where this fails to compile, it indicates a mistake, either an incorrectly declared overrriden virtual method, or a method that should be declared non-virtual. The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(), and CPDF_CustomAccess::GetFullPath(). These don't appear to be used anywhere, and are removed. Two members are removed that are no longer needed once those methods are removed. R=jam@chromium.org, jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/454983003

2014-08-05The root cause of this issue is shown as below:Jun Fang
Patterns are managed in CPDF_DocPageData. When a document is closed, all patterns will be released in the deconstruction of CPDF_DocPageData. However, some patterns which are referenced in CPDF_Color can't get the notification from the destroy of CPDF_DocPageData. It will cause use-after-free in CPDF_Color::~CPDF_Color.

2014-07-18pdfium: Fix all -Wdelete-non-virtual-dtor violations on Mac.Nico Weber
Calling `delete` on an object of a type that has virtual functions but not a virtual destructor is questionable: Since the object has virtual functions, it likely has subclasses, so if it's deleted through the base pointer and the destructor isn't virtual, the subclass destructor won't be called. In most cases, the classes getting deleted can just be marked final to tell the compiler that it can't possibly have subclasses (this also enables the compiler to generate better code). Two classes didn't have any sub- or superclasses but virtual functions - this doesn't make sense, so make all methods of these classes non-virtual. (Also delete an unused function on one of the two classes.) In one case, a class actually did have a subclass that needs to be deleted virtually, so mark one destructor as virtual.
