2015-07-01Revert "Revert "Redo range check in CPDF_SampledFunc::v_Call().""Tom Sepez
This reverts commit 327080bacabb3d90094144e66ae57037d4a8d8e6. This re-lands the patch, but removes the tests which would require 512MB buffers to be reliably allocatable on small bots. It also adds small fixes accumulated while diagnosing it. R=sanqingsong@gmail.com Review URL: https://codereview.chromium.org/1214403002.
2015-07-01Fix some clang warnings with -Wmissing-braces in pdfium.Nico Weber
Clang warns if there are missing braces around a subobject initializer. The most common idiom that triggers this is: STRUCT s = {0}; if the first field of STRUCT is itself a struct. This can be more simply written as: STRUCT s = {}; which also prevents the warning from firing. Other instances of the warning have been fixed by adding braces where appropriate.

2015-06-30Revert "Redo range check in CPDF_SampledFunc::v_Call()."Tom Sepez
This reverts commit 74742a75ac7a07c08cf36fe6f4eaa91bed8236a3.
2015-06-30Redo range check in CPDF_SampledFunc::v_Call().Tom Sepez
The current |bitpos1| calculation protects the passed argument to _GetBits32(): |bitpos.ValueOrDie() + j * m_nBitsPerSample|, but doesn't account for adding in the sample length in that routine. Also bound bits per sample to something reasonable to avoid undefined behaviour on the shift to compute the max value.

2015-06-18Fix CPDF_ICCBasedCS::GetDefaultValue heap-buffer-overflow.Tom Sepez
Introduced in ea44bd0. Re-animating the dead (code) usually turns out badly, and this is no exception. Make both of the uncallable methods go away. BUG=501889 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1179773007.
2015-06-16Add constructor for CPDF_ColorSpace.Tom Sepez

Make members protected and remove external manipulations. Move "*" into template since its always an indirection. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1182903002.
2015-06-12Remove unneeded checks in CPDF_DocPageData::GetFontFileStreamAcc().Lei Zhang
The input cannot be null. Same for CPDF_Document::LoadFontFile(). Also set the contract for CPDF_Document::LoadFont() and adjust callers accordingly. Also remove unused CPDF_Document::FindFont(). R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1184673002.

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

2015-06-04Move fx_safe_types.h to include/ directory.Tom Sepez
Small bit of OCD here, since this file is included cross-library (i.e. from fpdfsk), it can't be in src/. In other words, the following should be empty: grep -R 'include.*core/src/' fpdfsdk Fix some IWYU in it at the same time. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1147353006
2015-05-28Fix ALL the include guards.Tom Sepez
Get rid of leading _CAPITAL identifiers. A large number of these didn't actually match the filename. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1160443004
2015-05-21Fix four annoying warnings:Tom Sepez
Two "set but unused", one of which is surely an artifact from copying code around, and the other which ought to be used for the sake of clarity. Two are unknown "optimize" pragmas, remove them since the code has been shipped for years on other platforms under full optimization.

2015-05-19Re-land: Remove FX_Alloc() null checks now that it can't return NULL.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
2015-05-15Remove FX_NEW_VECTOR() macros.Tom Sepez

2015-04-22Add missing operators for CFX_ByteStringC.Tom Sepez
Removing the implicit cast operator forces a build breakage should we use ByteStringC in STL containers. Adding an operator< restores correct behaviour. Adding an operator[] avoids re-writing some code to call GetPtr() prior to array indexing. Part 1 of 4. R=thestig@chromium.org TBR=brucedawson@chromium.org BUG=pdfium:142.

2015-04-16Replace FX_NEW with new, remove tests from fpdfapiTom Sepez
Very few places where a change is required, but remove FX_NEW to show they've been audited. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1075953004
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.

space is used" This reverts commit 5a0e504d53195892458d819e52c62bea0c710bd5. Original review URL https://codereview.chromium.org/1009513003 Reason for revert: New "corpus" tests show that this is no longer rendering some images. See, e.g. http://chromegw/i/client.pdfium/builders/linux/builds/144/steps/corpus%20tests/logs/stdio for those that diff'd.

2015-03-16Fix a problem that JP2 image is not displayed because index color space is usedJUN FANG
There are two issues in this bug. One is that JP2 image is not displayed because it aborts loading Jpx bitmap when the number of components in color space is different with that one in JPX images. I found that the number of components in color space isn't updated after it's initialized. For index color space, the component shall inherit from its base color space. The second issue is that displayed color is not correct after I fixed the first issue. The root cause is that sRGB is used in JPX image, it doesn't need to map from index to RGB again. BUG=464215 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1009513003
