2017-11-29[CFI] Enable type generalization for LCMSVlad Tsyrklevich
Control Flow Integrity [1] indirect call checking verifies that function pointers only call valid functions with a matching type signature. This condition can be too strict, a common form of 'abstraction' relies on function pointers being cast to generalize argument pointer types to void*. In LCMS these failures occur because of casts of function pointers called as both _cmsInterpFn16 (cmsInterpFunction.Lerp16) and _cmsOPTeval16Fn (as an argument to _cmsPipelineSetOptimizationParameters) types making it difficult to refactor out easily. Instead, enabling the type generalization build config weakens the type checking performed for CFI-icall to accomodate this common type of casts.

2017-08-14LCMS: upgrade to 2.8Nicolas Pena
This CL upgrades LCMS from version 2.6 to 2.8. All changes from LCMS original version 2.8 are stored in patch files: - Patch 0: memory management modifications to use PDFium methods. This was previously not in any patch, so the changes were manually applied. - Patches 1-5: new patch files corresponding to old changes that can be seen in the history, but did not previously have patch files. - Patches 6-25: previous patches (patch numbers shifted by 6). The one for from16-to-8-overflow.patch was deleted as it was already upstream. Some patches did not apply cleanly so their .patch files were modified. - Patch 26: as I just moved files directly, unsupported characters were moved in unchanged, so I had to fix all of them: e with tilde and other characters were replaced to allow compilation on Windows. - Patch 27: Went over the code and re-applied changes that included comments clearly indicating this was Foxit. These changes are all already seen in the initial PDFium commit.

Changes in v2: 1) Since Chromium doesn't have //third_party:zlib (AKA a "zlib" target in //third_party/BUILD.GN) all the targets that depended on //third_party:zlib now depend on third_party:zlib, which always points to PDFium's third_party/BUILD.GN. The targets that depended on //third_party:zlib in third_party/BUILD.GN just depend on :zlib instead. 2) Move the zlib bits out of !build_with_chromium block.

2016-06-13fix skia + windows + gncaryclark
The Skia Windows build for PDFium differs from the Skia Chromium build in that it uses FreeType within PDFium and Direct Write within Chromium. This allows Chrome to match the UI of Windows, and allows PDFium to use FreeType to measure and draw. When PDFium was updated to use gn, the settings from Chrome were used as the basis for the PDFium settings. Subsequently, PDFium built with Skia on Windows drew text incorrectly as it used FreeType to look up the font glyphs and Direct Write to draw them. This fixes the gn files, and also fixes an error that crept into the now less-used gyp files. R=dsinclair@chromium.org BUG= Review-Url: https://codereview.chromium.org/2055353002

Remove several obsolete warnings from GYP build; Move disabled warning flags closer to the target instead of the whole package for GYP build; Use macro undefine instead of disabled warning for libtiff for GN build. Review-Url: https://codereview.chromium.org/1962863002
2016-05-05Resolve macro redefinition warnings when built in Chromiumweili
Chromium defines WIN32_LEAN_AND_MEAN on Windows. Third party library libtiff also defines it. So we undefine it before compiling libtiff code for GYP build. Also, remove _CRT_SECURE_NO_WARNINGS macro since it is redefined in zlib library as well. Our code no longer needs it. After fixing the above, re-enable warning flag 4005 which alerts about "macro redefinition". For GN build, we disable warning 4005 for compiling libtiff code before we can figure out another way to do this. Review-Url: https://codereview.chromium.org/1954773002

2016-04-27Allow overriding GN build flagsdsinclair
In order to enable XFA from GN builds we need to be able to override pdf_enable_xfa. To do this a build_overrides/pdfium.gni file needs to be created in Chrome. To use that, we have to create a build_overrides/pdfium.gni file in PDFium that just uses the default values. BUG=chromium:62400 Review-Url: https://codereview.chromium.org/1923333002
2016-04-20Standalone GN build.dsinclair
This CL setups up a standalone GN build. You'll need to set gn args similar to: use_goma = true clang_use_chrome_plugins = false pdf_enable_xfa = true pdf_enable_v8 = true pdf_is_standalone = true The third_party/pymock files are needed to make git cl upload work correctly.
