Bug ID: 47096
Summary: mw.LoadData results don't properly handle # operator
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Scribunto
Assignee: [email protected]

Classification: Unclassified
Mobile Platform: ---
When data is accessed through mw.LoadData, and that data contains nested
tables, the # operator (which is approximately but not exactly table length)
does not work correctly.
For example:
data = mw.LoadData( 'Module:MyData' );
Then asking for
#(data.sub_table)
Appears to be consistently wrong. I've worked up an example that seems to like
to show 0 consistently:
http://test2.wikipedia.org/wiki/Module_talk:LoadDataError
Experimenting with more complicated versions of this (i.e. tables nested inside
tables nested inside tables) led to even worse behavior that seemed to point to
uninitialized memory being returned, i.e. random values. It also managed to
trigger the Wikimedia Foundation Error Message in some cases with complaints
about out of memory errors. I'm not really sure why.
