[classad-users] Bug related to keywords

["Swaroop Sayeram" <swaroop@xxxxxxxxxx>]

Hello Folks,

I Just discovered a discrepancy regarding keyword parsing/unparsing when they happen to be identifiers.

 

I might be using an older version of the library, & maybe the classad developers have already fixed this issue. But let me run it through you guys anyway.

 

The issue is –

If we have a classad:

[‘error’ = 1]

In spite of the attribute name being a keyword the parsing succeeds because the name is quoted.

However when the ClassAd gets Unparsed, it spits it out as:

[error = 1]

Now if we try to parse this again, the parser bails out.

 

I’ve fixed this issue in both the Java & C++ libraries by getting the unparser to spit it out with single-quotes.

However, Im wondering, if that’s the best solution.

Would you rather have the parser succeed if it encountered “[error = 1]”, because the keyword is actually an attribute-name & hence the parser shouldn’t mind it.

 

Thanks,
