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).

2014-11-14Merge to XFA: Patch from CL 705503004Bo Xu
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.

2014-08-13Add FX_OVERRIDE and use it for virtual functions of FX_FINAL classes.Tom Sepez
Should there be cases where this fails to compile, it indicates a mistake, either an incorrectly declared overrriden virtual method, or a method that should be declared non-virtual. The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(), and CPDF_CustomAccess::GetFullPath(). These don't appear to be used anywhere, and are removed. Two members are removed that are no longer needed once those methods are removed. R=jam@chromium.org, jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/454983003

2014-07-30Speculative fix for uninitialized value in CFX_ByteString().Tom Sepez
If somehow different length values could be obtained by two successive calls to Doc_getFilePath() (and FieldBrowse() for that matter), and the method is true to the API documentation that says "The return value always indicated number of bytes required for the buffer, even when there is no buffer specified, or the buffer size is less then required", then it is possible to get a returned length describing memory beyond the current buffer. We can make the corresponding JS_docGetFilePath() method more robust against this case by applying better checks to the returned value. This probably is unrelated since ASAN seems to be flagging the corresponding bug as UAF, but doesn't hurt to make things more robust.
