| 13:23 | amend to [987067386fa2edae]: adding coverage for constructor too (just to ensure we don't fall into the same trap by constructors) check-in: eb467f0c52 user: sebres tags: trunk, main | |
| 12:59 | • Closed ticket [987067386f]: Parent-Class destructor not invoked with same class-name in different namespace plus 5 other changes artifact: fe845feaf2 user: sebres | |
| 12:56 | fixes [987067386fa2edae] don't use name of class in destructed hash, so ensure NS::C inheriting C would invoke destructor of base class (if both have destructors and clases have the same name) check-in: 883c2c383f user: sebres tags: trunk, main | |
| 12:54 | add test illustrating bug [987067386fa2edae]: NS::C inheriting C would not invoke destructor of base class (if both have destructors and clases have the same name) check-in: df20905f77 user: sebres tags: trunk, main | |

When a class is defined in a namespace and it inherits from a class with the same name from a different namespace and an object from the child class is destroyed, the destructor from the parent class does not get invoked. anonymous added on 2025-02-18 12:40:18: Previously submitted as https://core.tcl-lang.org/tcl/tktview/6d4319309e906144741e
PoC ...
namespace eval ::A {}; namespace eval ::B {}
oo::class create ::A::testCls {
superclass oo::class
destructor { puts "bye from ::A::testCls" }
}
oo::class create ::C::testOtherCls {
superclass ::A::testCls
destructor { puts "bye from ::C::testOtherCls"; next }
}
oo::class create ::C::testCls {
superclass ::A::testCls
destructor { puts "bye from ::C::testCls"; next }
}
set o [::C::testOtherCls new]
$o destroy
puts =================
set o [::C::testCls new]
$o destroy
## results to:
bye from ::C::testOtherCls
bye from ::A::testCls
=================
bye from ::C::testCls
bye from ::A::testCls
Although in tclOO inherited destructor need to be invoked explicitly (using next).
I guess, Itcl stores somewhere (hash table?) the chain of destructors by simple name (instead of its reference or fully-qualified name).

Yes, my suspicion about simple name in hash table has been confirmed... | ||||
