debug.getinfo()?

[PA <petite.abeille@...>]

Hello,

I have a little logging class where I use debug.getinfo() to build the 
context of a log call, e.g. the package and function name which invoked 
the log method.

For example, assuming an 'Example.lua' main chunk with the following 
log statements:

Log.debug( aDBMap.get( "DEC" ) )
Log.debug( aDBMap.hasKey( "DEC" ) )

Produces this output:

03/05 10:54:56 (Debug) Example.main: "December"
03/05 10:54:56 (Debug) Example.main: true

All in all, this work quite nicely. However, from time to time, 
debug.getinfo() seems to get confused. For example, the call after the 
ones above:

Log.debug( aDBMap.hasValue( "December" ) )

Produces the following output:

03/05 10:54:56 (Debug) Example.DEC: true

Note the "DEC" value for the function name, instead of "main" as for 
every other calls. How come? What is "DEC" doing there? "DEC" is the 
key for that value, but it shouldn't have anything to do with 
debug.getinfo(), isn't it? This is not critical, as it seldomly happen, 
but still, what would explain such confusion?

The relevant implementation of Log goes something like this:

        if ( ( aClassName == nil ) or ( aMethodName == nil ) ) then
                local someInfo = debug.getinfo( 3, "Sn" )

                if ( aClassName == nil ) then
                        aClassName = LUBundle.nameWithPath( 
someInfo.source )
                end

                if ( aMethodName == nil ) then
                        aMethodName = someInfo.name

                        if ( aMethodName == nil ) then
                                aMethodName = someInfo.what
                        end
                end
        end
