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.
2015-06-10Fix font rendering issues because of an incorrect transform.John Abd-El-Malek
This regressed in https://pdfium.googlesource.com/pdfium/+/71c24b839498fb89184002ed30fcff353e1e402c. The code would reach into FreeType internals and reset transform_flags. This would effectively set the font's transform matrix to the identity (since a transform is only used if the flag is set). I removed it because I assumed this is only a cache, and any other place that would call FT_Load_Glyph would have set a transform first. Apparently that's not the case (verified through adding some additional code). The fix is to reset the transform matrix after changing it. This is functionally equivalent to the previous behavior, since if the flag was 0 but there was a transform, it would be ignored until another transform is set.

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
It's redundant nowadays to provide our own equivalents, now that this is done for us by the system header. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1177483002
2015-06-08Remove more cruft from fx_system.hTom Sepez
- include system headers first and alphabetize. - remove unsupported FX_WIN32_MOBILE symbol. - actually define a FX_WIN64 symbol and make consistent. - use final/override, not FX_FINAL. - let stdint.h resolve FX_WORDSIZE concerns. - unused FX_ERR and FX_SUCCESS() macros. - unused FX_LSB_FIRST macro. - outline FX type deprecation plan.

2015-06-08Fix potentially massive memory leak in CPDF_DIBSource::LoadJpxBitmap().chromium/2429chromium/2428chromium/2427Lei Zhang
Leaks can happen in several places. For this particular bug, it happens when there is a colorspace component count mismatch. BUG=497191 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1153633009

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

2015-06-02kill IPDF_DocParser().Tom Sepez
Its fine to program to interfaces, but since the sole concrete implementation is in the same header as the interface, the code is bypassing it anyways. We can de-virtualize some things along the way, and remove two non-existent function prototypes from one of the headers. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1158053003
2015-05-28Fix ALL the include guards.Tom Sepez

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.

2015-05-21Fix an endless loop in CJBig2_HuffmanTable::parseFromCodedBufferJUN FANG
This issue is trigged by the conversion from unsigned int to signed int. A large unsigned int is converted to int. It's represented as a negative int which is used in the condition of while later. BUG=482639 R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1146913003
2015-05-20Integer overflow in CJBig2_Image::expandJUN FANG
1. New size should be larger than old size in JBig2_Realloc. 2. Arguments are integers but parameters are size_t in JBIG2_memset. After integer overflows, it will be presented as a huge unsigned number on 64 bits system.

2015-05-19Fix Heap Overflow in CJBig2_Image::expandJUN FANG
Integer overflow in CJBig2_Image::expand. It causes the size of reallocated is not expected. BUG=483981 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1131023008
2015-05-18Cleanup if early return from opj_j2k_copy_default_tcp_and_create_tcd().Tom Sepez
The opj_j2k_copy_default_tcp_and_create_tcp() function memcpy's a top-level struct, and then replaces pointers to memory owned by the original struct with new blocks of memory. Unfortunately, an early return can leave the copy with pointers to memory it doesn't own, which causes problems when cleaning up the partially-initialized struct. The referenced bug is triggered when we get a return at original line 7969 or 7385 due to OOM. Moral of the story: creating a "copy constructor" equivalent based on memcpy() instead of copying field by field for structs containing pointers is usually a bad idea.

2015-05-18Change FX_Alloc to FX_Try_Alloc in _JpegEncodeJUN FANG
This CL is used for: 1. keeping the same logic as before (the behaviour of FX_Alloc was changed for OOM). 2. fixing a potential integer overflow. BUG=N/A R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1126013006
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
2015-05-15Fix leaks in embedder test's FlateEncode() usage and in FlateEncode().Lei Zhang

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. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1128043009
2015-05-15Remove FX_NEW_VECTOR() macros.Tom Sepez

2015-05-15Fix potential UAF in ConcatInPlace.Tom Sepez
If ConcatCopy somehow gets a zero nNewlen, it returns early, without allocating a new m_Data. ConcatInPlace then frees the old one, leaving m_Data dangling. Also be concerned about the multiplication in the widestring version. So use wmemcpy and let the library cope with it. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1130763007

2015-05-11Create top-level public/ header directory.Tom Sepez
These are the only files that embedders of PDFium should be including. They are entirely self-contained, and compile cleanly against -Wall so as to not offend the code that may include them. Having done this, we can see that chromium is pulling in two additional files from the fpdfsdk/include/pdfwindow directory, which is not guaranteed to work. A few files are renamed, adding an "_" to make the names consistent. The exception is fpdfview, which is doc'd as such in the doc. Naturally, paths will need updating in a handful of files in chrome when this rolls in. BUG=pdfium:154 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135913002

Separate out the overload when the length is not known, and be sure that strlen() call is in the header so that strlen("foo") => 3 (since many compilers support this optimization).
