Massive extension of the fuzzer ( #1697 )
...
Fix bug where a `throw` was generated without expression
Reenable try/catch/finally and fix them up
Skip serialization errors
Allow function decl in other funcs but not in blocks etc
Rename function to be more appropriate
Fix global functions not getting certain names
Make the canaries more likely to appear as expressions
Add a silly rounding edge case
Add a new canary, `c`, which should only ever be incremented
Refactoring
Fix (another) iife not actually being invoked
When a statement hits recursion max return an expression instead of `;`
When a expression hits recursion max also inc `c`
Generate global code as well as function code
Also fixes some argument juggling related bugs.
No longer reduces the recursion max when generating sub functions.
Generates a function arg.
Add used names to var name pool while in that scope
This is a little wonky, possibly a hack, but since it's synchronous code I think it's alright to do this. The alternative is to slice the varnames array and juggle them through almost all the generator functions and there are various reasons why this patch is a better alternative.
Minify generated code, not beautified code. Prevents beautifier bias.
Prevent unnecessary duplication
Remove serialization protection because I think it got handled elsewhere
Abstract toplevel code generation
Add example line of running test case
Add poor man options parser, and some options
Reindent to 4 spaces
Lower chance of `default` generation
Comment example of testing a case and output improvement
Enable `default` clause appearing at any clause index
Removing some training wheels; dont add parens where we dont absolutely need them
Support `-s1` and `-s2` to force specific statements being generated at that recursion level
Add round number to output when failing. For stats and fun and profit.
Solidify statement depth counting. The argument juggling is real.
Renamed option to something long. -scf was ugly and probably confusing.
Fix missing arguments causing `canThrow` to be truthy, generating crashing code
Generate more binary nested expressions
Add black and white list cli options for statement generation
Allows you to explicitly require or forbid certain statements from/to being made.
```
node test/ufuzz.js --without-stmt switch,try -t 5 -r 5 -V
```
```
node test/ufuzz.js --only-stmt ifelse,expr -t 5 -r 5 -V
```
Similar granularity for expression may be added later.
There can be no comma between names; it just does a split on that arg.
Trim down the binary expression generator
Prevent scoping issues in nodejs by preventing certain names in global space
Oh this list was incomplete?
Allow bin-expr to generate assignments too. More vigilant with storing and reusing vars.
Add more global builtin names
Update wrapper code
Also patch Function valueOf
