| Summary | 0007133: CompiledMethod#getSourceFor:In: crashed for non-standard method signatures | ||||||||
| Description |
If a class refines Behavior#compilerClass with a custom compiler, the method CompiledMethod#getSourceFor:In: will crash because it does not take into account that methods may contain non-standard source code. In particular it is the piece of code in CompiledMethod#getSourceFor:In: that tries to replace selectors in the source code if they are different that given in the method dictionary. As a solution I suggest to just not doing any selector-magic when a class has a custom compiler. |
||||||||
| Additional Information |
To reproduce 1. Subclass Compiler and make it accept methods like 'Foo foo: Bar bar ^bar' (eg by removing all uppercase words from the to be compiler sources). 2. Make a class which uses the new compiler as its compiler. 3. Make a method with above content. 4. compile fine, but ... 5. crashed when IDE calls CompiledMethod#getSourceFor:In: |

#getSourceFor:in: class changed in trunk 4.1 The new version exploits trailer. Is this problematic ? Otherwise, subclass can also provide its own #getSourceFor:in: What do you think ? |

The old Traits implementation shared methods between traits and classes. If a method was renamed in a class or a trait, then the name was changed in #getSourceFor:in:. Since methods are no longer shared, this problem is solved. |
