Subject [jira] [Commented] (HTTPCORE-312) LengthDelimitedEncoder fails on content length > 32 bit
Date Mon, 17 Sep 2012 17:59:09 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13457198#comment-13457198

Roland Hänel commented on HTTPCORE-312:

Oleg, can you give me a hint what is the best way to get hold of the fix?

Can I download the not-yet-released 4.2.2 somewhere?

Or do I need to fix this myself, use my own btanch and jump on 4.2.2 as this becomes available?

Thanks for your really quick help. HttpCore is great stuff!

>             Project: HttpComponents HttpCore
>          Issue Type: Bug
>          Components: HttpCore NIO
>    Affects Versions: 4.2
>            Reporter: Roland Hänel
>            Priority: Critical
>             Fix For: 4.2.2
> The LengthDelimitedEncoder class fails to deliver contents that are larger than 2GB,
because the write(final ByteBuffer src) method incorrectly calculates
>    int lenRemaining = (int) (this.contentLength - this.len);
> For example, if this.contentLength is 3,000,000,000 and this.len is 0, then lenRemaining
will be negative and things will go wrong in the process.
> Changing the line to
>    long lenRemaining = this.contentLength - this.len;
> will fix this bug (maybe src.remaining() needs to be casted to (long) in the following
if statement).
