2018-09-13Revert "Make things more const-y"Tom Sepez
This reverts commit 882ed81dec7afc5bc106f965af34f1e59407fd95. Reason for revert: Rule out that this be making embeddertest flakey.

2018-09-13Introduce FX_Number class as a replacement for FX_atonum().Tom Sepez
The issue with FX_atonum() is that it doesn't return any information about whether it range-checked its integer values as a signed or unsigned type, even though it knows this as part of its processing. Rather than adding another out parameter to that function, create a class to hold all this information together. This is the first place things went astray while diagnosing bug 882959, in that a large positive value was cast to float as a negative value. Unfortunately, this doesn't affect the related bug, but is a step in the right direction.

2018-09-12Optimize CPDF_CMapParserRyan Harrison
In this parser, a vector of CodeRange values are built up during operations that need to be sync'd with the CPDF_CMap that is being initialized. In the existing implementation, the vector being built as a member var for the parser, and copying the values over to the cmap whenever there is a change. When profiling, this copy is where the code spends most of its time. The code has been rewritten to have the parser reference/modify the instance of the vector in the cmap instead of having its own copy. This removes all of the copies and significantly speeds things up.

2018-09-12Set correct stream index when parsing is done in several steps.Henrique Nakashima
When parsing happens in several steps (in pages with > 100 page objects), the position is reset to 0 and the start pointer is advanced. This breaks the calculation of which stream an object belongs to. Passing in the base pointer separately from the start offset allows the correct position to be calculated and the correct stream to be identified.

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.
