[jira] [Updated] (SOLR-2719) REGRESSION ReturnFields incorrect
parse fields with hyphen - breaks existing "fl=my-field-name" type usecases
[ https://issues.apache.org/jira/browse/SOLR-2719?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Luca Cavanna updated SOLR-2719:
-------------------------------
Attachment: SOLR-2719.patch
Right Yonik, I've been misled by the
{code}
String field = sp.getId(null);
{code}
at the beginning of QueryParsing#parseSort, while the method to look at was getSimpleName. Sorting is ok (but I don't completely understand the sp.getId at the beginning).
I attached a new patch: I added to StrParser a getFieldName method and added to getId the possibility to pass a vararg parameter of allowed trailing chars.
I made also some changes to ReturnFields to make the code a little bit more readable to me, hope is the same for you guys. Tests work.
I removed the weird tests about trailing tilde and so on, kept just the trailing dash test which now works (removed @Ignore).
Let me know what you think.
I'm going to open a new issue to add field names validation.

> fl=my-hyphen-field in query params parsed as "my" instead of "my-hyphen-field".
> OAS.search.ReturnFields use method getId() from OAS.search.QueryParsing
> in which check chars "if (!Character.isJavaIdentifierPart(ch) && ch != '.')"
> Hyphen is not JavaIdentifierPart and this check break when first "-" is found.
> This problem solve by passing '-' to check:
> if (!Character.isJavaIdentifierPart(ch) && ch != '.' && ch != '-') break;
> But I don't know how it can affect on whole project.
