2016-10-18Traverse PDF page tree only once in CPDF_Documentchromium/2895npm
In our current implementation of CPDF_Document::GetPage, we traverse the PDF page tree until we find the index we are looking for. This is slow when we do calls GetPage(0), GetPage(1), ... since in this case the page tree will be traversed n times if there are n pages. This CL makes sure the page tree is only traversed once. Time to load the PDF from the bug below in chrome official build: Before this CL: 1 minute 40 seconds After this CL: 5 seconds BUG=chromium:638513 Review-Url: https://codereview.chromium.org/2414423002

2016-10-17Fix segv in AddImage()tsepez
The assumption that only indirect objects would be passed is wrong. Restore old behaviour despite muddying ownership constraints. R=thestig@chromium.org BUG=656145 Review-Url: https://codereview.chromium.org/2425843002
2016-10-17Move fxge/android to if(is_android) on buildchromium/2894npm
core/fxge/android files all have if _FX_OS_ == _FX_ANDROID_. Instead, put the files inside if (is_android) on Build.gn. Also, the skia file is already under if (pdf_use_skia), so the if defined(_SKIA_SUPPORT_) can be removed. Review-Url: https://codereview.chromium.org/2413983004

2016-10-17lcms: reject NaN when reading float numberskcwu
LerpFloat functions expect input values are normal float. They first clamp values to the range of [0.0, 1.0] and then calculate interpolation with the input values. If the input value is NaN, it will lead to heap buffer overflow because the index to LutTable is calculated based on the said value and fclamp(NaN) is not in expected [0.0, 1.0] range. This patch rejects all NaN values earlier when reading float numbers. So it also changed behavior for cases other than LerpFloat. I think it is okay because NaN doesn't make sense for usual calculations. BUG=654676 Review-Url: https://codereview.chromium.org/2422553002
2016-10-17Strengthen bounds check in CWeightTable::Calc * part IIstackexploit
