Resolved for now

All the weirdness mentioned in the "Error messages" section has gone away now that I have temporarily patched Module:Convert to use Module:Mwlocal instead of Module:Mw. I think some change in Scribunto must have created a global mw variable, and there is some problem in the new code? And that caused the stuff below? Johnuniq (talk) 07:36, 13 February 2013 (UTC)

Error messages

The following conversions should give an error message as the result, but they should not give a "Script error".

• 1.2
• 1.2 xyz
• 1.2 ftin

---

Some results from various tests follow. I suspect these may not always occur as it may depend on some internal state of mw.lua or MediaWiki. I have definitely seen a "Script error" disappear (and stay disappeared after a browser refresh) when ?action=purge was appended to URL).

*{{convert}}              Script error
*{{convert|1.2}}          Conversion error: Need name of unit
*{{convert|1.2|xyz|m}}    Conversion error: Unit "xyz" is not known.
*{{convert|1.2|ftin|m}}   Conversion error: Unit "ftin" is invalid here.

Previewing following then gave these results:

*{{convert|1.2}}          Script error
*{{convert|1.2|xyz|m}}    Conversion error: Unit "xyz" is not known.
*{{convert|1.2|ftin|m}}   Conversion error: Unit "ftin" is invalid here.

Previewing following then gave these results:

*{{convert|1.2|xyz|m}}    Script error
*{{convert|1.2|ftin|m}}   Conversion error: Unit "ftin" is invalid here.

Previewing following then gave these results:

*{{convert|1.2|ftin|m}}   Script error

Previewing following then gave these results:

*{{convert|1.2}}          Script error

Previewing following then gave these results (all correct and as expected):

*{{convert|1.2|m|ftin}}   1.2 metres (3 ft 11 in)
*{{convert}}              Conversion error: Need value
*{{convert|1.2}}          Conversion error: Need name of unit
*{{convert|1.2|xyz|m}}    Conversion error: Unit "xyz" is not known.
*{{convert|1.2|ftin|m}}   Conversion error: Unit "ftin" is invalid here.

Conclusion: A bug somewhere requires the code in Module:Convert to run successfully once (without invoking Module:Mw) before a second erroneous template makes convert.lua uses mw.lua to report an error message.

Investigate problem using cutdown code

Following returns plain text if argument is "good", or an error message formatted by mw otherwise.

• [good][TWO]
• [bad][TWO]
