2015-06-17Replace some Release() calls with virtual destructors.Tom Sepez
A virtual method that does |delete this| is an anti-pattern. Some classes can be de-virtualized instead. Throw in some unique_ptrs and delete dead code for good measure. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1192013002.

2015-06-11Kill FXSYS_mem{cpy,cmp,set.move}{32,8}.Tom Sepez
At one point in time, it may have made sense to indicate the expected alignment of the memory you're about to copy, but that was last century. The compiler will take care of it just fine. I stopped short of removing the FXSYS_ wrapper macros entirely. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1179693003.

2015-06-10Remove FX_BSTR and FX_WSTR typedefs.chromium/2434chromium/2433chromium/2432chromium/2431chromium/2430Tom Sepez
These stand for const CFX_{Byte,Wide}StringC&, which is just monumentally confusing, since there are so many string types running around here. The following had manual changes: core/src/fpdfapi/fpdf_edit/fpdf_edit_content.cpp core/src/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp core/src/fpdfdoc/doc_form.cpp fpdfsdk/src/fpdf_ext.cpp R=thestig@chromium.org Review URL: https://codereview.chromium.org/1180593004.
2015-06-10Remove typdefs for pointer types in fx_system.h.Tom Sepez
This involves fixing some multiple variable per line declarations, as the textually-substituted "*" applies only to the first one. This involves moving some consts around following the substitution. This involves replacing some typedefs used as constructors with better code. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1171733003
2015-06-09Use stdint.h types throughout PDFium.Tom Sepez

2015-05-19Remove FX_Alloc() null checks now that it can't return NULL.Tom Sepez
This permits some functions to become void's since they, in turn, can't fail. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1142713005
2015-05-18Add safe FX_Alloc2D() macroTom Sepez
This avoids unchecked multiplications when computing a size argument to malloc(). Such an overflow is very scary, and can result in exploitable bugs. Along the way, kill off some return checks, since we know this can't return NULL. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1143663004

2015-04-27Reduce usage of operator LPCWSTR from CFX_WideString().Tom Sepez
This involves adding some explicit c_str() calls. Doing so flagged PDF_EncodeText() and FindOptionValue() as having suboptimal signatures, in that we are often throwing away a perfectly fine length and recomputing it. There are still some platform-specific code that needs the operator. R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1101933003
2015-04-27Revert "Kill operator LPCWSTR from CFX_WideString()."Tom Sepez
This reverts commit 15a62973b9b89c3e229cc0ab501c45967f91b325. Reason for revert: broke build on windows, mac. I must have missed some platform-specific conversions. TBR=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1108883002

2015-04-16Replace FX_NEW with new, remove tests from fpdftextTom Sepez
R=thestig@chromium.org Review URL: https://codereview.chromium.org/1085363003
2015-04-14Kill CFX_Object.Tom Sepez
CFX_Object is a type that implements its own new operators that return NULL on error. There's no need for this given the |new (std::nothrow)| syntax; in fact, the current code can only work if there is no activity in the constructors. This may explain the pervasive lack of constructors and reliance on Init() methods throughout the codebase. The activity takes place in fx_memory.h, where FX_NEW is mapped onto the std::nothrow syntax. The rest is just cleanup. Down the road, we will simply throw and remove all the error-checking paths for new objects. Landing this patch first will at least show a simple path back to the old behaviour without having to re-introduce CFX_Object should someone want to do so in their own fork.

2015-04-11Fix a heap buffer overflow issue in CPDF_CMap::GetNextCharJUN FANG

2015-01-06Resolve all but two VC++ build warnings in pdfium.Bruce Dawson
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.

There is an image object and text objects in this document, but the character in each text object is reversed. When rendering, the image object is shown. However, when highlighting, the text object is selected, resulting in text index issue. Moreover, the character in the document is in reading order, which is different from normal document.
