2018-05-25Replace some #ifdef PDF_ENABLE_XFA with runtime checks.Tom Sepez
Abstract GetUserPermissions() differences via new virtual method. Abstract GetPageCount() differences via existing virtual method. Remove unused ReadHeader() form for non-xfa. Remove unused FindSubstFontByUnicode() for xfa. Remove unused FXFONT_EXACTMATCH Change-Id: I0a3de01a9841db86fcbc96991d3fa2682393b9ad Reviewed-on: https://pdfium-review.googlesource.com/32831 Commit-Queue: Tom Sepez <tsepez@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org> Reviewed-by: Lei Zhang <thestig@chromium.org>
2018-01-17Correctly handle errors when starting jpeg codecRyan Harrison
The current implementation treats both returning false and longjmp'ing out of jpeg_start_decompress as indicating that the decompression has paused and needs more data. This is incorrect, in reality only the false return value indicates this. The longjmp path indicates a fatal error in the processing of the jpeg. The default implementation actually calls exit() in this case, and the documentation explicitly calls out that in this case recovery isn't possible and the decode process will have to start from scratch. This resolves a situation where the progressive decoder would get a malformed jpeg and keep on grabbing blocks from it and try to start decoding it. This would eventually fail when it ran out of data to read, but would cause a large memory leak and a crash on the MSAN fuzzers.
