2017-04-09enhance `test/ufuzz.js` (#1803)...- `-E` to report test cases with runtime errors - favor returning expressions rather than empty return - emit a newline upon fuzzer completion to not erase the iteration count closes #1800Alex Lam S.L

2017-04-01implement `test/sandbox.js` (#1749)...- `test/run-tests.js` and `test/ufuzz.js` now shares the same `run_code()` and `same_stdout()` - re-enable fuzzer to generate top-level `NaN`, `Infinity` & `undefined` - attempt to show beautified output only when `run_code()` output is preservedAlex Lam S.L
2017-03-31Massive 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 valueOfPeter van der Zee

2017-03-26ufuzz: workaround function name and toString() (#1688)...fixes #1686Alex Lam S.L
2017-03-26fallthrough should not execute case expression (#1683)...- de-duplicate trailing cases only, avoid all potential side-effects - enable switch statement fuzzing fixes #1680Alex Lam S.L
2017-03-26Improve fuzzer. :) (#1665)...@qfox Put value constants in a global constant 74c0fb9 @qfox And the other string based values as well a5033c5 @qfox Be more strict about parameters, allow max to be optional 9c7ce70 @qfox Support a `V` (capital) flag to only log out at intervals 2d822c7 @qfox Fewer magic variables a6a9a7c @qfox Fix decrement such that a function is created when n=1 7e4b017 @qfox Add more values 64e596e @qfox Make `b` appear more often d33191a @qfox Add functions that contain (only..) functions 29a86e3 @qfox Allow the block statement to contain multiple statements 7570484 @qfox Make the interval count a constant d587ad8 @qfox Enable mangling, disable post-processing … 4dc8d35 @qfox Add more simple value that may trigger syntactic errors 8496d58 @qfox Add `else` to some `if` statements a4aed65 @qfox Move iife to expr generator, fix missing recursion arg e453159 @qfox Improve output on error where it wasnt printing the last code properly 4565a1a @qfox Add switch statement to generator ceafa76 @qfox Add var statement, support optional comma for expr generator b83921b @qfox Expression generator should use a simple value instead of `0` as recu… … 9d1a5c7 @qfox const -> var to keep things es5... 0143099 @qfox Add more simple values that may trigger edge cases 5e124f1 @qfox Add central name generator, take special care for global functions aeb7682 @qfox Add some `return` and function declaration cases to statement generator 6c9c3cc @qfox Exclude switches from generator for now 91124b2 Put value constants in a global constant And the other string based values as well Be more strict about parameters, allow max to be optional Support a `V` (capital) flag to only log out at intervals Fewer magic variables Fix decrement such that a function is created when n=1 Add more values Make `b` appear more often Add functions that contain (only..) functions Allow the block statement to contain multiple statements Make the interval count a constant Enable mangling, disable post-processing Mangling is kind of the whole point... Similarly, to beautify the minified code afterwards may supress bugs so it's probably best not to beautify the code prematurely. And there's no point anyways since you won't see it most of the time and only care about the main input anyways. Add more simple value that may trigger syntactic errors Add `else` to some `if` statements Move iife to expr generator, fix missing recursion arg Improve output on error where it wasnt printing the last code properly Add switch statement to generator Add var statement, support optional comma for expr generator Expression generator should use a simple value instead of `0` as recursion default const -> var to keep things es5... Add more simple values that may trigger edge cases Add central name generator, take special care for global functions Add some `return` and function declaration cases to statement generator Exclude switches from generator for now Enable switch generation because #1667 was merged Add typeof generator Add some elision tests Add a new edge case that returns an object explicitly Add all binary ops to try and cover more paths Forgot four binops and added `Math` to var name pool Harden the incremental pre/postfix tests Improve switch generator, allow `default` to appear at any clause index Add try/catch/finally generation Prevent function statements being generated Add edge case with decremental op and a group Disable switch generation until #1679 and #1680 are solved Only allow `default` clause as last clause for now Tentatively enable `throw`, `break` and `continue` statements when in valid contextsPeter van der Zee
