supersedes #1723
fixes #1730 | Alex Lam S.L |
| 2017-03-31 | combine rules for binary boolean operations (#1744) | Alex Lam S.L |
| 2017-03-31 | 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 | Peter van der Zee |
| 2017-03-31 | sort options in alphabetical order (#1743)...They started off as functional groups I guess, but given the sheer number of options this is becoming too difficult to read. | Alex Lam S.L |
| 2017-03-31 | v2.8.20 | Alex Lam S.L |
| 2017-03-31 | fix missing preamble when shebang is absent (#1742) | Alex Lam S.L |

| 2017-03-30 | remove paranthesis for `-(x*y)` (#1732) | Alex Lam S.L |

| 2017-03-30 | improve tests from #1726 (#1729) | Alex Lam S.L |
| 2017-03-29 | speed up IIFE elimination (#1728)...- `side_effects` will clean up inner statements, so checking for an empty function body should suffice
- drop side effects when dropping `return` from statement | Alex Lam S.L |
| 2017-03-29 | speed up `equivalent_to()` and `AST_Switch` (#1727) | Alex Lam S.L |

fixes #1725 | Alex Lam S.L |
| 2017-03-29 | output optimal representations of NaN & Infinity (#1723)...- move these optimisations out from `Compressor` to `OutputStream`

| 2017-03-29 | remove UGLIFY_DEBUG (#1720)...fixes #1719 | Alex Lam S.L |
| 2017-03-29 | fix corner case in `unused` (#1718)...When fixing catch-related issue in #1715, it tries to optimise for duplicate definitions but did not take anonymous functions into account.
Remove such optimisation for now and we can cover this as a more general rule later. | Alex Lam S.L |
| 2017-03-28 | v2.8.17 | Alex Lam S.L |
| 2017-03-28 | fix `unused` on var of the same name within catch (#1716)...fixes #1715 | Alex Lam S.L |

| 2017-03-28 | drop anonymous function name when overshadowed by other declarations (#1712)...fixes #1709 | Alex Lam S.L |
| 2017-03-28 | handle var within catch of the same name (#1711)...The following code prints `1`:
var a = 1;
!function(){
a = 4;
try{
throw 2;
} catch (a) {
var a = 3;
}
}();
console.log(a);
fixes #1708 | Alex Lam S.L |
| 2017-03-28 | fix tail trimming of switch blocks (#1707)...now guarded under `dead_code`

| 2017-03-28 | fix mangle for variable declared within catch block (#1706)...fixes #1704 | Alex Lam S.L |

| 2017-03-27 | fix typeof side effects (#1696)...`statement_to_expression()` drops `typeof` even if it operates on undeclared variables.
Since we now have `drop_side_effect_free()`, replace and remove this deprecated functionality. | Alex Lam S.L |
| 2017-03-27 | preserve side effects in switch expression (#1694)...fixes #1690 | Alex Lam S.L |
| 2017-03-27 | fix `cascade` on anonymous function reference (#1693)...Unlike normal variables and even function definitions, these cannot be reassigned, even though assignment expressions would "leak" the assigned value as normal. | Alex Lam S.L |
| 2017-03-27 | handle overlapped variable definitions (#1691)...Process variable definitions with or without assigned values against:
- `arguments`
- named function arguments
- multiple definitions within same scope
Essentially demote variable declarations with no value assignments.
Also fixed invalid use of `AST_VarDef` over `arguments` - should use a member of `AST_SymbolDeclaration` instead. | Alex Lam S.L |
| 2017-03-26 | fix `delete` related issues in `collapse_vars` and `reduce_vars` (#1689) | Alex Lam S.L |
