2018-01-26Clean up construction of CFX_BarcodeRyan Harrison
Because certain enum values can cause the initialization of the class to fail there is a seperate init method from the constructor. This CL is converting the code to use a standard factory pattern for this, instead of the existing implementation.

This CL reduces the memory limit in pdf_codec_jbig2_fuzzer. Note that MSAN requires the limit to be lower than the actual bot usage limit. In the testcase, we get OOM just after CFX_DIBitmap::Create.

2017-11-01Move some XFA JS code into fxjs/Dan Sinclair
This CL renames cxfa_scriptcontext to cfxjse_engine and cxfa_fm2jscontext to cfxjse_formcalc_context. From reading the code, the script context appears to handle the v8 setup and object code. The formcalc context code is related to handling the JS code generated from the transpiler. I, think, these new names make the intended usage clearer. They also move the code into fxjs/ to keep along side the rest of the JS code.

This is being done to remove non-useful OOM reports for very large images and improve fuzzing efficiency, since larger images are unlikely to cover new logic.

2017-09-22Fix crash when rendering invalid GIFRyan Harrison
The core fix in this CL is a change to how LWZ decompression works, so that when the min code table size and the color palette size are different, color codes after the end of the defined color palette are considered errors. This CL also introduces a bunch of tweaks to the call return path, since there were multiple locations where the GIF decode failing status was being dropped on the floor, so the end widget would have a bitmap with the default colour in it, instead of nothing.
