2018-09-04Avoid CHECK in fpdf_parser_decode.cpp (memcpy empty span)Tom Sepez
Given a span of size N, memcpy(dest, &span[N], 0) ought to be a no-op, but since we compute span[N] before checking for zero length, we hit an assert. The correct idiom should be to create a sub-span, which allows specifying N, but only when the size is 0.

2018-08-30Fix lifetime issue in CCodec_ProgressiveDecoder.Tom Sepez
The associated bug is caused by failure to clean up context before returing at line 740 or so. But cleanups are fragile, so instead do not move context out of a local until success. This in turn means passing the local to one helper rather that using the stored value and confirming this is the only helper method invoked during the time in which the context is not yet stored.

2018-08-22Properly handle language markers in decoded textRyan Harrison
In text like document title 0x001B is used as a marker for the beginning/end of a language metadata section. Currently PDFium does nothing with this data, but when returning the 'decoded' text it needs to be stripped out. The existing code assumed that the two bytes following a marker would be the data to be removed and did nothing to track if it was in/out of one of these regions. This led to a situation where it would always strip the two bytes following the region, since it assumed the end marker was the beginning of a new region. This CL corrects the detection and handling of these regions, and adds a regression test for the reported bug.
