2016-10-24Fix root dictionary leak in cpdf_document_unittestNicolas Pena
The CPDF_Document does not own its root dictionary, so add ownership in CPDF_TestDocumentForPages, using ReleaseDeleter because the dictionary cannot be deleted. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/2445753002 .
2016-10-21Add CPDF_Document::GetPage() unittestschromium/2899npm
Added a nontrivial page tree and a test that pages are being fetched properly, both when requested in order and in reverse order. This will help prevent introducing bugs while changing the way the page tree is processed. BUG=chromium:638513 Review-Url: https://chromiumcodereview.appspot.com/2435783006

When linearized document have hint table, The FPDFAvail_IsPageAvail return true, but FPDF_LoadPage return nullptr, for non first pages.

2016-10-18Traverse PDF page tree only once in CPDF_Documentchromium/2895npm
In our current implementation of CPDF_Document::GetPage, we traverse the PDF page tree until we find the index we are looking for. This is slow when we do calls GetPage(0), GetPage(1), ... since in this case the page tree will be traversed n times if there are n pages. This CL makes sure the page tree is only traversed once.

2016-10-17Fix segv in AddImage()tsepez
The assumption that only indirect objects would be passed is wrong. Restore old behaviour despite muddying ownership constraints. R=thestig@chromium.org BUG=656145 Review-Url: https://codereview.chromium.org/2425843002
2016-10-17Move fxge/android to if(is_android) on buildchromium/2894npm
core/fxge/android files all have if _FX_OS_ == _FX_ANDROID_. Instead, put the files inside if (is_android) on Build.gn. Also, the skia file is already under if (pdf_use_skia), so the if defined(_SKIA_SUPPORT_) can be removed. Review-Url: https://codereview.chromium.org/2413983004

2016-10-17Revert "Make CPDF_Object containers hold objects via unique pointers."tsepez

2016-10-17Strengthen bounds check in CWeightTable::Calc * part IIstackexploit
This CL implemented a better version of CWeightTable::GetPixelWeightSize(), which will calculate the size of array PixelWeight.m_Weights correctly to prevent potential heap buffer overflow conditions.

2016-10-14Update CPDF_IndirectObjectHolder APIs for unique objects.tsepez
Doing so highlights a few places where ownership is dubious. Add convenience functions to return an unowned reference to a newly-created indirect object. Review-Url: https://codereview.chromium.org/2419173002
2016-10-13Make CPDF_Object containers hold objects via unique pointers.tsepez
This tweaks the implementation while leaving the API the same. The API change is more disruptive, so break this part off first. Review-Url: https://codereview.chromium.org/2385293002
2016-10-13Optimize roll operator in CPDF_PSEngine some more.thestig
Also move code that belongs in an anonymous namespace into one. Review-Url: https://codereview.chromium.org/2416703002
2016-10-13Make CPDF_Image() constructors saner.chromium/2890tsepez
Introduce the UniqueDictionary typedef and friends, to allow moving to unique_ptrs before the Release() deleter issue is fully resolved. This will go away down the road. Review-Url: https://codereview.chromium.org/2420743002
2016-10-13Put CPDF_StreamContentParser into its own .cpp/.h filestsepez
No functional changes. Make many of its methods private. Review-Url: https://codereview.chromium.org/2415943003
2016-10-13Clean up fx_basic_util a littlenpm
- Nit fixes. - Remove unused methods. - Replace FX_BOOL with bool. Review-Url: https://codereview.chromium.org/2419433004
2016-10-13split CPDF_StreamContentParser::AddImage() into 3 overloads.tsepez
Small step before making CPDF_Image stream ownership saner. Review-Url: https://codereview.chromium.org/2416733002
2016-10-13Verify number of ex flags matches number of ex items.dsinclair
Currently the JBig2 decoder can leak subimages in the case where we mark more items in EXFLAGS then we have SDNUMEXSYMS. This Cl checks for this condition and fails the decode if it happens. BUG=chromium:654365 Review-Url: https://codereview.chromium.org/2419553002
2016-10-12Convert from int to float values.dsinclair
The CPDF_Page::GetDisplayMatrix expects to set float values into the |display_matrix| but all of the input values are currently int. It is possible to overflow the int values, so this CL changes the variables to be int which closer reflects what they're being used for. BUG=chromium:652038 Review-Url: https://codereview.chromium.org/2412983002
2016-10-12Reduce code duplication in CPDF_Type1Font::LoadGlyphMapnpm
Added methods SetExtGID and CalcExtGID for this purpose. Changed protected to private: no one inherits CPDF_Type1Font. Review-Url: https://codereview.chromium.org/2412483006

2016-10-12Get rid of CFX_ArrayTemplate<CPDF_Object*>tsepez
They won't work with std::unique_ptr down the road, so replace with std::vector. Review-Url: https://codereview.chromium.org/2411703003
2016-10-12Optimize roll operator in CPDF_PSEngine.thestig
Rolling 0 times is a no-op. Rolling 0 items is a no-op. Rolling N items J times is the same as rolling N items J % N times. This also avoids an integer overflow corner case. BUG=chromium:648077 Review-Url: https://codereview.chromium.org/2412833002

2016-10-11Fix negative font rendering on Mac by reversing matrix c component.npm
Notice that this is just making it analoguous to how it works when the font is positive: the b and d components are reversed. Currently, when the font is negative, only the a component is reversed. The c one needs to be reversed as well. BUG=chromium:653941 Review-Url: https://codereview.chromium.org/2411833002
2016-10-11Slightly simplify CFX_FontMapper::FindSubstFontnpm
- Deleted useless flag FXFONT_SUBST_STANDARD - Change kExternalFontIndex to something more meaningful - Fetch symbolic fonts using UseInternalSubst too Review-Url: https://codereview.chromium.org/2400773002
2016-10-10Move ToString() and friends from CPDF_Object.h to CPDF_String.htsepez
Ditto with the other ToXXX functions to CPDF_xxx.h. Shortly, we will want to introduce another variant: inline std::unique_ptr<CPDF_String> ToString( std::unique_ptr<CPDF_Object>); This will require that CPDF_String be complete which is not the case in the CPDF_Object.h header. Rather than dragging all the other .h's into it, move these to the subclass headers. That way, these will be together when the new form is added.

2016-10-10Add method to convert to an indirect object in a dictionary.tsepez

2016-10-06Split m_InstalledTTFonts into two vectors to avoid sketchy logic.npm
Instead of relying on ' ' to determine whether the CFX_Bytestring is added on one place or another, use another vector. When trying to match fonts from the fontmapper, compare with both vectors. BUG=pdfium:510 Review-Url: https://codereview.chromium.org/2395883002

FX_BOOL can be replaced by bool. Also replaced in a couple other places so that Winbots pass. Review-Url: https://codereview.chromium.org/2395803002
2016-10-04Fix ownership when making a private annot dictionary into a shared one.tsepez
There's no way to take ownership back from the CPDF_Array without deleting the object, so add a new primitive to make elements become indirect rather than manipulating them outside the class. This should solve the ASSERT(objnum == 0) issue that blocked the previous roll. Review-Url: https://codereview.chromium.org/2391883003
2016-10-04Avoid crashing on CPDF_ToUnicodeMap::Load by using ValueOrDefault()npm
