2018-02-19Simplify CXFA_FMToken creationdan sinclair
This CL converts the CXFA_FMToken usages into an object instead of a pointer. A copy constructor has been added. The line number was removed from the token and is retrieved from the lexer where needed.

2018-02-19Simplify formcalc token listdan sinclair
The keyword list in the formcalc lexer is only used to match identifiers. We don't need to store the non-identifier tokens in the list, so they're removed. The hash is removed and the list is compared by string instead. The token names have been moved to DEBUG so they won't be included in Release builds.

2018-02-15Add limit to number of formcalc expressionsDan Sinclair
Currently it's possible to create a formcalc script which creates a large number of expressions. This will eventually cause stack exhaustion as we try to allocate the needed expression objects. This CL limits the number of parsed expressions in the PostExpression section in order to keep from failing due to stack overflow.

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 CL makes the use of CXFA_IsTooBig consistent and universal across all of the ToJavascript and related methods. Previously this method was only applied in some calls. It is now being tested as a precondition and postcondition on every call and as a post condition for the entire translation process. There are some size checks within methods that potentially generate large amounts of JS that have been left in.

2017-10-25Add in depth check for ToJavascript and related methodsRyan Harrison
There exists a similar check for the parser, but it doesn't catch all cases of excessive memory usage, since a single parse step can generate multiple expressions that need to be converted or other cases where the parse depth doesn't match the emission depth later. Due to the expressions appearing in two different inheritence hierachies the depth information needs to be stored outside of the classes, thus the new depth class. Another way to handle this would be to change the method calls to take in a visitor object that tracks depth. This would require significant reworking of some of the code, so I am going to file a bug about doing that conversion as a cleanup.
