Subject [jira] [Updated] (LUCENE-3976) Improve error messages for unsupported Hunspell formats
Date Tue, 24 Apr 2012 12:49:37 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3976?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Luca Cavanna updated LUCENE-3976:
---------------------------------

    Attachment: LUCENE-3976.patch

First draft patch: I added a check for that specific problem with an understandable error.
In fact, since we are going to read the first 5 elements from an array, better to check if
there are at least 5 elements.
Not sure how we can improve generic errors handling. Let me know your thoughts.

> Our hunspell implementation is never going to be able to support the huge variety of
formats that are out there, especially since our impl is based on papers written on the topic
rather than being a pure port.
> Recently we ran into the following suffix rule:
> {noformat}SFX CA 0 /CaCp{noformat}
> Due to the missing regex conditional, an AOE was being thrown, which made it difficult
to diagnose the problem.
> We should instead try to provide better error messages showing what we were unable to
parse.
