2017-01-03Check for overflow in JBig2 Huffman decoderDan Sinclair
This CL updates the Huffman decoder in the JBig2 codex to check the low field does not overflow. BUG=chromium:675236 Change-Id: I7f5f6fe8329df4ece6f317fac521fe2373686479 Reviewed-on: https://pdfium-review.googlesource.com/2131 Reviewed-by: Tom Sepez <tsepez@chromium.org> Commit-Queue: dsinclair <dsinclair@chromium.org>

2017-01-03Kill last use of CFX_PtrList.tsepez
I'd been waiting on this hoping the code would be refactored out of existence, but it looks to be used. Use tests against x.end() in place of a "null position". This is greatly complicated by the use of "tail position", which now calcluated by std::prev(x.end()) unless the list is empty. Review-Url: https://codereview.chromium.org/2592163002
2017-01-03Remove CFWL_ListBox::GetDataProviderItemTextDan Sinclair

2017-01-03Cleaning out params in CPDFXFA_ContextDan Sinclair

2017-01-03Use return values in CFWL_Scrollbar instead of out paramsDan Sinclair
This CL updates CFWL_Scrollbar use return values instead of using out params. In some cases, the same values is assigned and passed in, but passing in the const ref is a lot clearer as to what is happening.

2017-01-03Force stop of page tree traversal when max level reachedNicolas Pena
The previous implementation, FindPDFPage, was already doing this since the recursive call was always with return. Currently, we were trying to keep going even after reaching max level. The problem is that if the page tree is not a tree, we might loop forever. This could also be solved by keeping track of the dictionaries that have been visited, but this solution takes much less space.

2017-01-02Gold support in PDFiumchromium/2970stephana
Extends the PDFium tests to collect images and meta data to be uploaded to Gold. This feature is triggered by adding the --gold_* flags. It extends pdfium_test to output the MD5 hash of the underlying pixel buffer for each page it renders. That output is then processed by test_runner.py to generate the gold meta data. This behavior is modeled after the 'dm' tool in skia. See https://skia.googlesource.com/skia/+/master/dm/DM.cpp#1090 This should not cause any change in the current behavior of the tests, it will be trigger once we update the buildbot recipe.
