2015-07-20Merge to M44: Fix an integer overflow issue in openJpegchromium/2403Lei Zhang
Fixing this issue for an urgent request. It should be fixed in OpenJPEG side. BUG=506763 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1231933008 . (cherry picked from commit d1b0a8d9dc71c67b4ce67f148cebc01d66d1d983) Review URL: https://codereview.chromium.org/1245853002 .
2015-07-13Merge to M44: Integer overflow in CJBig2_Image::expandLei Zhang
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.

2015-07-13Merge to M44: Cleanup if early return from ↵Lei Zhang
opj_j2k_copy_default_tcp_and_create_tcd(). 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.

2015-07-13Merge to M44: Fix an endless loop in CJBig2_HuffmanTable::parseFromCodedBufferLei Zhang
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 (cherry picked from commit bc4b82ea7a9c6603c6a1c89e00f4e6381c1b6804) Review URL: https://codereview.chromium.org/1231923006 .
2015-07-13Merge to M44: Fix heap use after free in Document::DoFieldDelay and ↵Lei Zhang
Document::delay This fix removes CJS_DelayData object from m_DelayData array and copies them to a new array, before processing them. So contents of m_DelayData array cannot be used after they get freed.

2015-07-13Merge to M44: Abort on OOM by default in FX_Alloc().Lei Zhang
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 (cherry picked from commit 9f6f34892fdfff87c49a9df4c1e34790c0fa1272) BUG=446032 Review URL: https://codereview.chromium.org/1226403008 .
2015-06-12Merge to M44: Fix 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. BUG=479434 R=thestig@chromium.org, tsepez@chromium.org Committed: https://pdfium.googlesource.com/pdfium/+/e4503ea9947d2f9c61704da20271b413a364a9c0 Review URL: https://codereview.chromium.org/1186603003.

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.

2015-05-13Set 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.

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

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.

2015-05-01Adjust 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".
