2016-11-18Add unit test for CXFA_FileRead.tsepez
The FileRead's return convention is being modified at https://codereview.chromium.org/2430743003/, so first provide a test of the old behaviour. Fix some issues with null dictionaries as provided by the CPDF_Stream default ctor along the way. Review-Url: https://codereview.chromium.org/2517513003
2016-11-17fix corpus testscaryclark
All corpus tests draw reasonably well. There are pixel differences, but no missing features or large scale errors. This was verified by running run_corpus_tests.py on skiapaths and agg build dirs, then running the skdiff tool to generate a report of the pixel difference. For example, after running $ ninja -C out/skia skdiff $ ./out/skia/skdiff /repo/pdfium/out/agg/gen/pdfium/testing/corpus/ /repo/pdfium/out/skiapaths/gen/pdfium/testing/corpus/ ~/aggskiadiffs view the report in a browser at ~/aggskiadiffs/index.html R=dsinclair@chromium.org BUG=skia:5973 Review-Url: https://codereview.chromium.org/2504863003
2016-11-17Move CPDF_RenderStatus from render_intnpm
Moved CPDF_RenderStatus to its own class and removed unused methods. I only added some spaces and removed some {}s in cpdf_renderstatus.cpp. Will do cleanup of the file as a followup because it would be too hard to keep track of what's changed in this CL. Review-Url: https://codereview.chromium.org/2513693002
2016-11-17Move CPDF_DocRenderData from render_intnpm

2016-11-16Move ByteStringPool from document to indirect object holder.tsepez

2016-11-14Make CPDF_PageContentGenerator methods take object numberstsepez
This patch fixes a possibility that an owned CPDF_Stream is handed to the indirect object holder inside RealizeResource(). Its arguments are changed to take an object number, as is done elsewhere in the code, to suggest that only indirect objects are acceptable. BUG=660756 Review-Url: https://codereview.chromium.org/2489423002
2016-11-14Properly release caches in CPDF_DocRenderDatanpm
Currently, only RemoveRef() is being called when releasing. The problem is that when the object is no longer being used, the map is not updated accordingly. In the pdf in the bug below, the pointer of a font used in the second page coincides with the pointer of a font in the first page (that was released). So the cached values for the font in the first page are used, resulting in incorrect rendering. BUG=pdfium:629 Review-Url: https://codereview.chromium.org/2501053002
2016-11-11Relax colorspace checks in CPDF_DIBSource::CreateDecoder().chromium/2917thestig

2016-11-09Do not load main cross ref table for first page in linearized pdf.art-snake

2016-11-09Add early returns in CJBig2_TRDProc::decode_Arith when decode fails.npm

2016-11-04Traverse PDF page tree only once in CPDF_Document Try 3npm
Now, we do not start traversal from where we were at, but from the top. This makes the code less prone to bugs, as now there is no need to call methods to recursively fix things. This will save a lot of time when the trees are rather flat, as in the PDF file in the bug. It can still be slow, for instance if we have a chain of page nodes, and the last in the chain contains all of the pages (this is artificial). Try 2 at https://codereview.chromium.org/2442403002/ Also added test where Try 2 would have failed.
