Subject [jira] [Comment Edited] (IGNITE-4331) Binary marshaller does not preserve component type when deserealizing even basic array typed fields
Date Tue, 29 Nov 2016 17:26:58 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-4331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15705926#comment-15705926

-----------------------------------------------------------------------

Non working query example:

{code:sql}
SELECT byteArrFld FROM SomeObject WHERE someIntFld > 5
{code}

where {{byteArrFld}} is a field of type {{java.lang.Byte[]}} (array of byte wrappers).

Again: query will return result, but it will be {{Object[]}}, not {{Byte[]}} as the user would
probably expect. And returned value will be impossible to use as the value for the same field.

>             Project: Ignite
>          Issue Type: Sub-task
>          Components: binary
>    Affects Versions: 1.8
>            Reporter: Alexander Paschenko
>             Fix For: 2.0

> How to reproduce: try to deserialize *single* field having type of {{Byte[]}} or any
other primitive wrapper type array. It will be deserialized as {{Object[]}} and won't be suitable
even to set the same field's value again - metadata check on object building will fail as
required ({{Byte[]}}) and given ({{Object[]}}) types won't match.
> As agreed with [~vozerov], currently we're not fixing it. Probably will get back to this
while working on 2.0 release.
> Discovered by [~skozlov] while running SQL DML examples during 1.8 release QA process,
exact reasons found by [~al.psc].
