2014-12-29Fix the big integer bug in PDF417.Bo Xu
Previously no big integer support in Pdfium and XFA. The PDF417 barcode functionality could not work properly. BUG=https://code.google.com/p/pdfium/issues/detail?id=98 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/777553002
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.

2014-12-19XFA: merge patch from CL 815103002Bo Xu
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

Add a small LRU cache for the JBIG2 symbol dictionary. This reduces rendering time on my test document by over 10 seconds. It is super common for a JBIG2 dictionary to span multiple pages, so we don't want to decode the same dictionary over and over again.

2014-12-19XFA: merge patch from CL 441988Bruce Dawson
Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables. QeTable is a 752 byte array that was defined in a header file. This caused it to be instantiated by the VC++ compiler 12 times, wasting 8,272 bytes of space in the data segment. Because 'const' implies 'static' this did not cause any duplicate symbol errors. JSCONST_n*HASH are a set of eight variables that are defined in a header file. This causes them to be replicated 15 times. The variables themselves are tiny but they are dynamically initialized and this dynamic initialization code is replicated 15 times. When tested on pdfium_test.exe the effect of this change is to: Reduce the .text (code) segment by 3,616 bytes. Reduce the .rdata section by 8,656 bytes. Reduce the total binary file size by 13312 bytes. These are the worst offenders for pdf.dll as shown in: https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0 This will also drastically simplify the list of work to be done for bug 441899 (getting rid of initializers).

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.

Change from 'this' to L'this' and remove the cast that was hiding this mismatch. Found by VC++'s /analyze. Warning was: fpdfsdk\src\javascript\js_runtime.cpp(352) : warning C6276: Cast between semantically different string types: char * to wchar_t *. Use of invalid string can lead to undefined behavior. This mismatch has been there as far back as the history goes (to May of this year). It looks like a real bug to me. However I don't know the implications of this bug and why it would not have been noticed at run-time. The code has been this way as far back as the git history goes, but that is only to May 2014.
