Key declarations on virtual relvars ignored

I doubt this so much a bug but more likely a limitation: when I declare a virtual relvar with a non-empty <candidate key def list> it doesn't get enforced. Furthermore there's no note of it existing in the catalog either. It would be good to add this to the Limitations section of the web site. Perso...

Re: User-Defined Types in Java

Cool. We much prefer the new Tutorial D native user-defined types anyway but I just thought I'd mention it since it's shipped as a demo example.

Re: Forum Bug

No worries. I was just very confused until I realized because I'm usually very good at remembering passwords, given a few tries.

User-Defined Types in Java

The old Rel web site had substantial information on Rel's capability to accept user-defined type definitions written in Java, but I can no longer find this information any more. We have a student that wants to use the Date type defined in the provided TypeDate.d script, but an error message appears....

Minor Bug on Windows

In Rel version 0.3.17 Alpha the provided script files for Windows, DBrowser.bat and Rel.bat, attempt to pass command-line parameters using Unix notation and Rel complains bitterly about it.

No biggie, but it has confused some of our users.

Java stack dump when using wrong data type

One of our students uncovered the following bug in Rel 0.3.17 Alpha. TYPE DATE POSSREP { c CHAR CONSTRAINT LENGTH ( c ) = 8 AND IS_DIGITS ( c ) }; VAR TEST BASE RELATION {ID INTEGER, D DATE} KEY{ID}; TEST := RELATION {TUPLE {ID 1, D "15061989"}}; The value "15061989" is a character string literal wh...

Incorrect Parsing

The <substitute> operator does not always parse correctly. Example: UPDATE S (STATUS := 17) The opening parenthesis is interpreted as being part of the expression to perform substitution on rather than the beginning of the assignment. It is taken as denoting the opening parenthesis for a user-define...

Re: Backup in 0.3.9 on Windows Vista uses invalid filename

Sounds like putting a colon in the filename caused an NTFS Alternate Data Stream to be written to, which is pretty sweet because most applications don't understand them.
