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
This Cl switches the ownership between the parser and the document. Previously the parser owned the document and we'd jump through hoops during cleanup to delete the right object. This Cl flips the ownership so the document owns the parser and simplifies the cleanup logic where needed. BUG=pdfium:565 Review-Url: https://codereview.chromium.org/2275773003
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

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.

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.

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.

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].
