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
2015-05-15Abort on OOM by default in FX_Alloc().Tom Sepez
Add a FX_TryAlloc() for those few cases where we might need to continue in face of OOM. Remove FX_AllocNL() (the context of its use would suggest that NL means "No Limit"). This is used for some big allocations, so replace it with TryAlloc(). Large allocations may be worth trying to continue from, since there are few and they have a large chance of failing.

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.

2014-12-19Update freetype to 2.5.4.Bo Xu
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

2014-09-15Add a boundary check before accessing the table of 'Index to Location'Jun Fang
Before this fix, only |gindex < face->num_locations| is checked. However, the pointer, p, will be moved to next location in the first FT_NEXT_ULONG or FT_NEXT_USHORT. It may cause a crashier. So a boundary check is needed before the second FT_NEXT_ULONG or FT_NEXT_USHORT. BUG=412457 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/571833002

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

When an image object is zoomed in by a big factor, the scaling factor in the transformation matrix is big as well, resulting in a large |dest_width| and |dest_height| value(they can be think of as the equivalent pixel size of the entire image, although most of it is outside the device).

2014-07-18pdfium: Fix all -Wdelete-non-virtual-dtor violations on Mac.Nico Weber
Calling `delete` on an object of a type that has virtual functions but not a virtual destructor is questionable: Since the object has virtual functions, it likely has subclasses, so if it's deleted through the base pointer and the destructor isn't virtual, the subclass destructor won't be called. In most cases, the classes getting deleted can just be marked final to tell the compiler that it can't possibly have subclasses (this also enables the compiler to generate better code). Two classes didn't have any sub- or superclasses but virtual functions - this doesn't make sense, so make all methods of these classes non-virtual. (Also delete an unused function on one of the two classes.) In one case, a class actually did have a subclass that needs to be deleted virtually, so mark one destructor as virtual.

2014-07-16Remove uninitialized const global g_GbFontNameMap.Nico Weber
C++11 makes uninitialized const PODs an error, because they contain uninitialized memory (they're uninitialized that can never be initialized (because they're const). In this case, the memory was only used by _GetSubFontName() if the lang parameter was 1, but _GetSubFontName() is only called from one place, with a lang parameter of 0. So remove _GetSubFontName()'s lang parameter too. (Using bsearch for searching an array that always has exactly 2 entries is overkill too, but I'm trying to keep the diff small.) No intended behavior change. Fixes this error on the clang/win bot: ..\..\third_party\pdfium\core\src\fxge\win32\fx_win32_device.cpp(207,20) : error(clang): default initialization of an object of const type 'const _FontNameMap [1]' const _FontNameMap g_GbFontNameMap[1]; ^ BUG=chromium:82385 R=bo_xu@foxitsoftware.com Review URL: https://codereview.chromium.org/369343003

2014-05-20Fixed or silenced all warnings and turned on warnings-as-errors.John Abd-El-Malek
- Silence -Wheader-hygiene warning on Clang. Between fx_agg_driver.cpp and fxjs_v8.h there are hundreds or thousands of things that depend on "using namespace", so it is best to just suppress this warning than fix it. - gzguts.h: Include unistd.h on all non-Windows platforms, not just Apple platforms. Fixes implicit include warnings on Linux. - Added parens to silence a warning about mixing && and ||. - Removed a check if an enum is negative. Enums can be unsigned, generating an always-false warning. The check isn't necessary. - Removed some statements that are just names of variables that do nothing.
