2016-08-29Verify element exists before accessing.dsinclair
Currently when the parser utility classes are outputting to a text buffer we do not verify that an element from an array exists before accessing. We can have null items in arrays (and dictionaries but the dictionary case is already handled). This Cl updates the code to check the element exists before attempting to use the element.

In [1], it was made a mistake in the way the test case testing/resources/pixel/bug_492.pdf was generated. This CL aims at fixing this mistake by: 1- keep making use of the new pdfium_test capability introduced by [1], 2- add a proper .in file for the test case to generate its respective .pdf file.

2016-08-26Add -> operators to CFX_CountRef.chromium/2842tsepez
Allows CFX_CountRefs to behave more like pointers. Rename SetNull() to Clear() for consistency with other ptrs. Change GetPrivateCopy() into MakePrivateCopy() with no return, since the -> operators are clearer than getting an object pointer. Review-Url: https://codereview.chromium.org/2283113002
2016-08-26Rename CPDFSDK_Annot::GetType to CPDFSDK_Annot::GetAnnotSubtype.jaepark
CPDFSDK_Annot::GetType should be renamed to GetAnnotSubtype as it returns annotation subtype. Also, CPDFSDK_Annot::GetSubType is only used to check if the annotation is signature widget. Thus, change the method to IsSignatureWidget. Lastly, rename CPDF_Annot::GetSubType to CPDF_Annot::GetSubtype to match with spec. Review-Url: https://codereview.chromium.org/2287703002

2016-08-26Extend pdfium_test capability so that more Javascript can be executedchromium/2841tonikitoo
In [1], the lack of support of pdfium_test to some application level hooks was felt. More specifically, the lack of implementation of the hook FFI_GetPage, called when 'this.getAnnot()' is executed in an Acrobar JS context, makes it non-trivial to JS texts that manipulate PDF annotations. [1] https://codereview.chromium.org/2265313002/ Here is the failing call stack in pdfium_test: 0 ::RenderPdf (samples/pdfium_test.cc) 1 ::FORM_DoDocumentOpenAction (fpdfsdk/fpdfformfill.cpp) 2 CPDFSDK_Document::ProcOpenAction (fpdfsdk/fsdk_mgr.cpp) 3 CPDFSDK_ActionHandler::DoAction_DocOpen (fpdfsdk/fsdk_actionhandler.cpp) <----v8----> 4 Document::getAnnot (fpdfsdk/javascript/Document.cpp) 5 CPDFSDK_Document::GetPageView (fpdfsdk/fsdk_mgr.cpp) 6 CPDFDoc_Environment::FFI_GetPage (fpdfsdk/include/fsdk_mgr.h) (frame 6 returns nullptr, and getAnnot call in frame 4 bails) CL extends pdfium_test app with a FFI_GetPage hook implementation. Basically what FFI_GetPage does is returning a FPDF_PAGE instance. In case of pdfium_test, FPDF_PAGE instances were only created on demand when the page was going to get rendered, and then discarded. Since FFI_GetPage can be called by JS before pages are rendered, CL moved the page creation code into a helper function, and cached the FPDF_PAGE instances created in a map, so it does not recreate them needlessly.

2016-08-24Removing CPDF_Parser::CloseParser.chromium/2839dsinclair
Currently the only calls to CloseParser() happend in the destructor or the start*Parse methods. The Start*Parse methods are currently only called on freshly constructed parsers in fpdf_dataavail and fpdfview. This CL removes the CloseParser() method and puts the contents in the destructor. We then add an ASSERT that we don't re-enter the parser after it has already completed the parse. Review-Url: https://codereview.chromium.org/2267173005

2016-08-24Allow CPDF_Font to use fallback fontsnpm
Added a vector of pointers to CFX_Fonts in the class CPDF_Font, so that fallback fonts may be used. In CPDF_CharPosList::Load, the glyphs for each character are calculated. When m_Font does not support a character, a fallback font is selected and the character is rendered using that font. This meant adding an attribute to FXTEXT_CHARPOS so it knows which font renders it. Also, methods in fpdf_render_text.cpp now may need to call device drawing methods multiple times because these only support one font at a time. In CPDF_TextRenderer::DrawNormalText and in CPDF_TextRenderer::DrawTextPath, the device drawing method is called as few times as possible by grouping contiguous characters rendered by the same font. In CPDF_RenderStatus::DrawTextPathWithPattern, drawing was already done one character at a time, but precalculating CFX_FaceCache. Now, the face cache is precalculated for all of the fallback fonts. The list of fallback fonts does not include tha main font. Otherwise the list would be of raw pointers to avoid double free problems. For now, the font Arial is used as fallback. This should fix the issue of not seeing Latin characters displayed when bad fonts are used. However, this should be improved. Tested manually using the file in the bug, plus a font directory containing a font that supports Hangul but not Latin. This font is chosen as the substitute font, but Latin characters are now being rendered. Design proposal: go/pdfium_fallbackfonts BUG=pdfium:358 Review-Url: https://codereview.chromium.org/2276653002
2016-08-24Flip document and parser ownershipdsinclair

2016-08-24Lazy generate an "AP" when an Annot's hidden state changestonikitoo
Now that Document::getAnnot works and annotation instances can have its properties changed, consider the following scenario: - A PDF content has an annotation without AP and CPVT_GenerateAP is called to generate one. - However the annotation also has its hidden flag set (/F 2), and CPVT_GenerateAP bails out earlier, not generating an AP. - When the PDF's Javascript runs, it acquires an instance of this annotation object, bounded to JS using Document::getAnnot(), and set its "hidden" flag to false. - At this point, the annotation should get drawn, but it does not because its "AP" was never generated. CL fixes this scenario by making PDFium able to lazy generate APs, if needed. BUG=pdfium:492 Review-Url: https://codereview.chromium.org/2265313002

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

2016-08-23[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.
