2018-08-08Limit size of expression list in FormCalc parserchromium/3517Ryan Harrison
Limits the number of elements that can be added to the expressions list in the FormCalc parser. This handles cases like long strings of ! repeated, since ! is a valid identifier and identifiers are valid expression, even though it will be no-op. This is another case of something that is valid, but stupid.

2018-06-14[formcalc] Calculate length of string when calling FXSYS_wcstofDan Sinclair
When calling the FXSYS_wctof method we currently pass in -1 from AdvanceForNumber. This tells the method to calculate the string length. This can be slow for a formcalc string with a lot of numbers. This CL changes the call to pass in the length of remaining data in the original string. This takes the MSAN runtime of the case in the linked bug from ~21seconds to ~500ms. The debug runtime goes from ~2s to ~500ms.

This CL changes the formcalc JS conversion code so that method calls no longer generate exponential amounts of JavaScript. Previously we'd duplicate the code to call into a method twice. This would then generate twice once for arrays and once for other types of object. This CL changes the code to wrap the actual method call into a JavaScript function which will be used from both the array and non-array calling code. For the referenced bug, the generated JS originally needed a buffer of 365meg to generate. With this CL, it needs a buffer of 7.5k.

2018-02-19Simplify CXFA_FMToken creationdan sinclair

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.
