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.

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

2016-10-10Move 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

2016-10-04Fix 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

2016-10-04Use FX_SAFE_UINT32 on CPDF_ToUnicodeMap::Loadnpm
m_Map maps to unsigned integer, but m_MultiCharBuf.GetLength() returns an integer. There will be integer overflow if the length is big, and UBSAN will complain. Thus, using FX_SAFE_UINT32. Replacing with uint32 would work as well: the point is to consider the length as uint instead of int. BUG=chromium:652232 Review-Url: https://codereview.chromium.org/2393573002

2016-10-03Assert that only 0-numbered objects are Released()tsepez
This condition holds because numbered objects are brute-force deleted by the indirect object holder, rather than being released. Be careful about recursive deletion, check before advancing, since we no longer count on Release() doing this for us. Fix a few tests where the test was violating ownership rules. This should be the last step before completely removing Release() in favor of direct delete everywhere. Review-Url: https://codereview.chromium.org/2375343004

2016-10-03Detect resursive loading of type3 font char to avoid infinite loopweili
The original way of detecting loops was passing a level parameter through various functions. This missed some cases which also lead to load type3 font char, for example, FindFont() may call CheckType3FontMetrics() which may eventually lead to LoadChar(). The new way is to store the char loading depth, and abort when the depth exceeds the max. BUG=chromium:651304 Review-Url: https://codereview.chromium.org/2384853002
