2016-08-23Fix stack overflow in object Clone() functionsweili
For some complex objects such as CPDF_Dictionary, CPDF_Array, CPDF_Stream, and CPDF_Reference, Clone() could be executed with infinite recursion to cause the stack overflow. Fix this by checking already cloned objects to avoid recursion. BUG=pdfium:513 Review-Url: https://codereview.chromium.org/2250533002
2016-08-23Fix page leaks in an embedder testweili
Embedder test's delegate function GetPage() calls FPDF_LoadPage() to load a page which may be already loaded by embedder test itself. Thus the page's ref count is increased unnecessarily. This causes the page to be leaked. Fix this by putting the page map in embedder test class and guarantee the page is loaded only once. Also, fix leaks in this embedder tests by unloading the loaded pages to properly release the resource. BUG=pdfium:242 Review-Url: https://codereview.chromium.org/2258333002
2016-08-23Make indirect object holder private.dsinclair
This CL moves the m_IndirectObjs map to be private to the IndirectObjectHolder. Various bits of code have been updated to use the accessors to the map. This CL fixes the issue with the last time this landed by removing the objnum check from GetIndirectObject() which appears to have caused the crashes.

2016-08-23[XFA] Force destruction order of font managers.chromium/2838dsinclair
The GEFont points to the font manager which creates it and tries to unregister itself. Currently the GEFont can be created by the default mapper and then stored in a different mapper. If the default mapper is destroyed first, when the second mapper cleans up the font there will be a call to unregister on the default mapper causing a use-after-free. The long term fix is to fixup the GEFont so it points to the correct mapper to unregister from. This CL forces the destruction order in CXFA_FFApp to cleanup the non-default mapper first.

2016-08-22Implement Field::SetHidden using Field::SetDisplay.chromium/2837tonikitoo
Following up on [1], where the duplicated logic in Field::SetDisplay was factored out into a helper function, CL further cleans up a related method: ::SetHidden. Field::SetHidden(true), for instance, is equivalent to calling Field::SetDisplay(1), whereas Field::SetHidden(false) is equivalent to Field::SetDisplay(0); No behavior change is expected.

2016-08-22Destroy window before cleaning up comboboxdsinclair
Currently, when we destroy a CFFL_ComboBox we'll cleanup the fontmap and then call the destructor for the parent type. This will case the PWL_Wnd to be destroyed. In this case, the window is a PWL_Edit. On destruction it will reset the focus which causes the text selection to change, which asks the font map for data but we've already destroyed the font map. This CL forces the destruction of the window earlier in order to have the fontmap available. A followup bug is filed to correct the location of the fontmap so we don't have this dependency.

2016-08-19Stub out Document::syncAnnotScan method.chromium/2834tonikitoo
The PDF specification [1] says: " syncAnnotScan guarantees that all annotations will be scanned by the time this method returns. (..) Normally a background task runs that examine every page and looks for annotations during idle times. " The statement details specifically how Acrobat implements this method. Although, neither the method itself nor the background scanner task are implemented in PDFium (as of today, Ago/2016), not having ::syncAnnotScan at least stubbed out can be considered harmfull since its absence makes JS acrobat scripts silently fail when it has a call to it. Given that, and following a stub-out pattern present in other methods including ::addAnnot and ::addField, CL provides a stubbed out implementation of Document::syncAnnotScan.

2016-08-18Add initial Document::getAnnot supportchromium/2833tonikitoo
CL implements the first step in order to support Annotations manipulation in PDFium: Document::getAnnot. The method takes two arguments, an integer (page number) and a string (annotation name). When called, it iterates over the annotations on the given page number, searching for the one whose name matches the string in the second parameter. If found, then an Annot instance (see Annot.cpp/g added by this CL), is bound to a Javascript object and returned. With the use cases described in bug [1] as an initial test case, CL adds support to the following Annotation object properties: - hidden - name - type Idea is to keep evolving the implementation with more methods and properties in follow up CLs.

Currently the timers is a vector. When we cancel a timer we have an O(n) operation to remove the timer. If there are a lot of timers (which this test has > 16k) this can take a long time. The impact is a lot lower in Release, but the test is very slow in Debug.

2016-08-16Hidden annotations should not be drawntonikitoo
Now that PDFium supports drawing of more annotation types, it should also respect the "hidden" flag that annotations might feature. For instance, in IE/Acroread if an annotation is flagged as "hidden" it does not get drawn. CL adds a check for the specific "hidden" flag, not drawing annotation that are flagged with it, in order to match IE + acrobat reader behavior. The "flags" definition can be seen by looking at "/F {value}" syntax in a PDF file source, where {value} is an predefined integer value. Test: PDF files being added in [1].

Currently the GetWidget call will create a backing widget for a control behind the scenes if it doesn't exist.

This created structure will then be torn down as we don't need it anymore once we're done with the widget. For the instances where setting the value on the widget will have no effect (as we'll destroy it anyway) we can tell GetWidget() to not create the widget and return without doing any work.
