["William Bardwell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13087075#comment-13087075 ] 

William Bardwell commented on TS-922:
-------------------------------------

I think that is on purpose, that just means that it doesn't know how big the data is going to be.  (That number is INT64_MAX.)  It happens with things like chunked data.

> when I use null-transform plugin and print some debug info, I find the TSVIONTodoGet() return a huge member, I consider it maybe has a bug !
> The details shows below:
> code in null-transform.c:
>   TSVIO input_vio;
>   int64_t towrite = 0;
>   int64_t avail = 0;
>   towrite = TSVIONTodoGet(input_vio);
>   TSDebug("null-transform", "\ttoWrite is %" PRId64 "", towrite);
>   if (towrite > 0) {
>     /* The amount of data left to read needs to be truncated by
>      * the amount of data actually in the read buffer.
>      */
>     avail = TSIOBufferReaderAvail(TSVIOReaderGet(input_vio));
>     TSDebug("null-transform", "\tavail is %" PRId64 "", avail);
> #if MDSN_LOG
> 	if (log) {
> 		TSTextLogObjectWrite(log, "handle_transform() with data to write  length: %" PRId64 ", IOBufferReader available data length: %" PRId64 "", towrite, avail);}
> #endif
