Andres Almiray updated GROOVY-8149:
-----------------------------------
Affects Version/s: 3.0.4
> Bad Compiler Performance in case of syntax errors when using many subscript
> operators
> -------------------------------------------------------------------------------------
>
> Key: GROOVY-8149
> URL: https://issues.apache.org/jira/browse/GROOVY-8149
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.3.7, 2.5.0-alpha-1, 2.4.10, 3.0.4
> Environment: Windows 7
> Reporter: Ivo Colombo
> Priority: Minor
>
> See the following script with a Syntax error (unbalanced parentheses), which
> repeatedly uses the subscript operator to set something on an object which
> has the putAt method defined:
> {code}
> class A {
> void putAt(key, value) {
> // whatever
> }
> }
> def a = new A()
> a[1] = (
> a[2] = 2
> a[3] = 3
> a[4] = 4
> a[5] = 5
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> a[1] = 0
> {code}
> Expected: The compiler returns with a syntax error.
> Observed: The script takes very long (in the order of minutes) to compile. If
> it is shortened (remove some of the assignments), at some point it compiles
> within reasonable time (< 1 Minute), but still slow. The syntax error is
> reported correctly.
