GCPDF_CIDFont::_CharCodeFromUnicode There is not a code page (CP) used for converting unicode to mutli-bytes if the coding scheme is CID coding. Only return 0 if CID can't be retrieved.

2015-04-03Merge to XFA: Add embedder test comparing with the last patch.JUN FANG
When there is a wrong keyword like '??ze' in the dictionary of the trailer, PDFium can't recognize it and aborts further parsing. After this change, PDFium continues even it can't get the right size at this moment. It will rebuild the cross reference table later since the size of the table is missing.

This issue was caused by integer overflow in CPDF_SampledFunc::v_Call. The root cause of this issue is that the content in the test pdf file was damaged. The solution is to check whether an integer is overflow before using it. BUG=452455 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/886953002

None of these are currently reachable because the IsSafeMode method always returns true. This, in turn, will let us kill off some file (as in fopen()) based parsing. That, in turn, will let us kill of some more now-unreachable code. In general, we don't want to have unsafe modes.

2014-12-23XFA: merge patch from CL 733693003, getting rid of more castsBruce Dawson
Getting rid of more (FX_LPCWSTR) casts and fixing two bugs revealed by this. Since casts to FX_LPCWSTR have been shown to hide bugs I tried removing more of them, targeting those places where a cast was used to force a conversion from CFX_WideString to FX_LPCWSTR, replacing these casts with calls to the newly added .c_str() function. This revealed two places where the cast was hiding a bug -- where ->c_str() was required instead! This removes ~33 FX_LPCWSTR casts and there are ~31 left, many of which will go away in some future change. Also includes this change: Removing unnecessary casts from wchar_t* to wchar_t*, by various names.

2014-12-23XFA: merge patch from CL 727083002, zero local variables.Bruce Dawson
Zero initialize ch to avoid possible bug - conditions are very subtle. Whether ch and iRet are read without being initialized depends on complex preconditions and cannot be determined by looking at these function. Therefore it seems prudent to zero initialize them to avoid any risk.

Update freetype to 2.5.4. Put freetype into third_party directory, cleaning up header files. Previously freetype header files are in core/src/fxge/freetype and core/include/thirdparties. There were also multiple fx_freetype.h. This patch removes the additional Foxit wrapper to make further update easier. Notice, for original freetype source code, the following files are modified and need to be updated accordingly in future update: third_party/freetype/include/config/ftmodule.h third_party/freetype/include/config/ftoption.h BUG=407341 R=thestig@chromium.org Review URL: https://codereview.chromium.org/815103002

Fix blank page issues caused by too strict check Before this fix, PDF parser aborts the parsering process when detecting an error. For this case, PDF parser just gives up parsering when it detects that the length of image stream is incorrect. The solution to this case is to find the tag "endstream" and "endobj" to calculate the length rather than aborting the parsering process.
