2015-05-19Re-land: Remove FX_Alloc() null checks now that it can't return NULL.Tom Sepez
Fixes the ordering of some assignments broken when converting to checked numerics in CFX_PathData::AddPointCount(). Original Review URL: https://codereview.chromium.org/1142713005 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135893008
2015-05-19Revert "Remove FX_Alloc() null checks now that it can't return NULL."Tom Sepez
This reverts commit eb6527763171cdb4b0fbfea5a20d691f4d67b660. Reason for revert: broke javascript tests. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1145843005
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
2015-05-19Fix 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.

2015-05-19Replace v8::Handle with v8::Local and v8::Persistent with v8::GlobalJochen Eisinger
those types are just aliases, and we should consistently use the new version R=tsepez@chromium.org BUG= Review URL: https://codereview.chromium.org/1138823004
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

2015-05-17Replace deprecated with non-deprecated V8 APIsJochen Eisinger
In most cases, we just CHECK() that no exception was thrown. Previously, we'd just crash. Ideally, this should all be fixed and the system should cope with those exceptions, but that's beyond this CL. R=tsepez@chromium.org BUG= Review URL: https://codereview.chromium.org/1126203010
2015-05-15Fix leaks in embedder test's FlateEncode() usage and in FlateEncode().Lei Zhang
For FlateEncode(), error handling code leaked memory. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1144603002

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
There isn't much point in having macros that obscure obvious language features. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1135273004
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

2015-05-14Use phantom handles instead of weak handlesJochen Eisinger
Phantom handles allow for freeing objects with one pass of GC. However, this means that by the time the callback is invoked, the v8 object already does no longer exist. To avoid accidential access to the dead object, there are now two callbacks, where the first must only reset the handle, and the second does the clean-up work.

2015-05-13Tidy public/ directory.Tom Sepez

2015-05-13Set pointers in internal fields directly instead of wrapping themJochen Eisinger
The internal fields are scanned by the garbage collector, so they can't contain arbitrary data. However, aligned pointers are supported by the V8 GC, so the V8 API allows for setting a pointer directly instead of wrapping it in an External container. Not only is this faster, but it's also required for the new v8::Global API which I'm going to update to in a follow-up patch.

2015-05-12Make (and verify) public/ files compile under C.Tom Sepez
This involves adding some missing extern "C" { } declarations, using FPDF_ types instead of C++ types, and converting pass by reference arguments into pointers. Test this using fpdfview_embedertest for simplicity. BUG=pdfium:158 R=thestig@chromium.org Review URL: https://codereview.chromium.org/1130843003

2015-05-12Restore checked strlen conversions.Tom Sepez
The checked conversion can be re-enabled now that there is a public API free of private headers like this one. This reverts commit 6661fd4c26106cd530d187b36f29be7e5c98b70f. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1133323003

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

This gets included in chromium's pdfium_engine.cc, and thus must pass a higher error level. There's probably a follow-up to check why the FPDF_ api doesn't insulate chromium from this file. TBR=thestig@chromium.org Review URL: https://codereview.chromium.org/1127043004

2015-05-05Expose additional flags for rasterization.Scott Byer
These flags are unused in Chromium, but are needed for the Cloud Print conversion process, which takes PDF and produces a raster for low-end printers. Certain low-end printers (e.g., B&W laser printers) will turn anti-aliased text into a mess. The existing printing flag isn't sufficient, as other kinds of printers will still want some kinds of anti-aliasing to occur for best results.

2015-05-05Make sure string constructors are efficient on literalsTom Sepez
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).

2015-05-01Adjust the visibility of the standalone targets in the GN build.Dirk Pranke
As part of the migration from GYP->GN, we want to make sure that we can track when new targets are added to either the GYP or GN builds and that we are building everything we expect to build. In GN, unlike GYP, if a build file gets referenced from other files, building 'all' will cause every target to be built in it. This means in particular, that we can end up trying to build targets that are not necessarily intended to be visible to the rest of the build. To get around this, any target that is defined but hidden (like 'pdfium_unittests', ) should still be visible to a top-level target called "//:gn_visibility".
