[TCLCORE] namespace resolution of srcCmd in "interp alias"

[Gustaf N. (sslmail) <ne...@wu...>]

Dear all,

I was recently caught by a mistake which is not easy to spot. In the following script,
- the namespace resolution of the unqualified name “NAME1” when creating a proc leads to "[namespace current]::NAME1", while
- the namespace resolution of the unqualified name “NAME2” when creating an alias leads to “::NAME2”.

The following snippet creates via interp alias the cmd ::log

namespace eval ::ns1 {
    proc log args {puts stderr "LOG called"}
}
namespace eval ::ns1::sub {
    proc foo {} {
        log foo
    }
    interp alias {} log {} ::ns1::log
}

while the following leads to the result i was expecting. Same results on Tcl8 and Tcl9

All the best 
-g


namespace eval ::ns1 {
    proc log args {puts stderr "LOG called"}
}
namespace eval ::ns1::sub {
    proc foo {} {
        log foo
    }
    interp alias {} [namespace current]::log {} ::ns1::log
}
