Re: [scim] [Technical Errata Reported] RFC7644 (4670)

[Steve Moyer <[e-mail]>]

Phil,

I agree with Chris ... I think his proposal allows compound expressions within the valFilter.  If you're interested, we will change the ANTLR grammar of our lexer/parser and test the results.  We'd also be happy to add test cases that the SCIM community deems useful.  The current lexer/parser tests are *ONLY* testing grammar so they ignore whether the attribute names are valid from a schema perspective.  We're tracking the issue with our code here:

https://github.com/PennState/SCIMple-Identity/issues/15

We're also testing all the example filters from the protocol specification as well as a bunch that should fail.  Since the original lexer/parser was written in August/September of 2013, the square bracket syntax wasn't included in our tests.  If anyone is willing to provide examples of passing and/or failing filters (based on the SCIM specification's intent), we'd be happy to add them to our test suite.  Please add them as comments to this issue #15 (above) on GitHub.

Thanks,

Steve

P.S.  Our pre-errata ANTLR grammar is available at https://github.com/PennState/SCIMple-Identity/blob/develop/scim-spec/scim-spec-protocol/src/main/antlr4/edu/psu/swe/scim/server/filter2/Filter.g4.  We'll be updating the grammar and replacing the original SCIM filter with the results once we have it proven out.
