Chris Lott commented on WAGON-518:
----------------------------------
That test is still pending, thanks for asking. My initial test was in a little
library that uses Wagon. The real test must wait for another component that
uses the little library.
> AbstractHttpClientWagon#putFromStream() reads entire content to memory
> ----------------------------------------------------------------------
>
> Key: WAGON-518
> URL: https://issues.apache.org/jira/browse/WAGON-518
> Project: Maven Wagon
> Issue Type: Bug
> Components: wagon-http
> Affects Versions: 2.12
> Reporter: Chris Lott
> Assignee: Michael Osipov
> Priority: Major
> Fix For: 3.1.0
>
>
> Method putFromSteam in class AbstractHttpClientWagon seems to violate the
> implied contract of working with streams. It uses much memory because it
> first consumes the input stream argument, then transfers that content. The
> code that consumes the stream is in the private class
> RequestEntityImplementation ctor:
> {code:java}
> byte[] bytes = IOUtil.toByteArray( stream );{code}
> Please revise it, if possible, to behave more like the superclass
> StreamWagon's putFromStream method, which does the transfer straight from the
> input stream.
> We are attempting to PUT some 150MB artifacts in a java microservice that
> runs with rather sharp memory limits. As a local workaround we increased the
> JVM's -Xmx argument but that way lies madness.
> Thanks in advance for any suggestions or workarounds.
