2015-02-10Merge to XFA: Fix heap buffer overflow in CPDF_SampledFunc::v_CallJUN FANG
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

2015-02-05Kill off some dodgy JS callbacksTom Sepez
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.

2015-01-08XFA: merge patch from CL 792953005, fix most warningsBruce Dawson
Includes fixes to XFA specific warnings -- benign truncations. Bug https://code.google.com/p/pdfium/issues/detail?id=104 was filed to track changing types to avoid some truncations. Resolve all but two VC++ build warnings in pdfium. pdfium builds on Win32 have about 85 warnings (250 in the XFA branch, totaling over 480 lines!), mostly from four lines in a header file and a warning that should be disabled. This change resolves all but two of them and turns on warning-as-errors. Bugs have been filed for the two remaining warnings: https://code.google.com/p/pdfium/issues/detail?id=100 the 64-bit warnings: https://code.google.com/p/pdfium/issues/detail?id=101 and the Linux warnings: https://code.google.com/p/pdfium/issues/detail?id=102 The fix to the double->float truncation bugs will also improve code-generation.

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.

2014-12-19XFA: 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.
