Ajay Shenoy commented on AXIS-2574:
-----------------------------------
I am trying to apply the patch but I am getting the following line
$ pwd
/home/ShenoA/patch/axis-src-1_4/axis-1_4/src/org/apache/axis/client
$ patch -d . < /home/ShenoA/patch/Call.diff
Looks like a unified context diff.
I can't seem to find a patch in there anywhere.
I am new to applying patches, Can someone tell me what I am doing wrong and
what is the correct command ?
> Reading an attachment (slowly) can cause resource deleted error

>
> Key: AXIS-2574
> URL: https://issues.apache.org/jira/browse/AXIS-2574
> Project: Axis
> Issue Type: Bug
> Components: Basic Architecture
> Affects Versions: 1.2.1
> Reporter: Steve Sowerby
> Attachments: Call.diff, Call.diff
>
>
> When reading the data from an attachment we periodically get the following
> error:
> java.io.IOException: Resource has been deleted.
> at
> org.apache.axis.attachments.ManagedMemoryDataSource$Instream.read(ManagedMemoryDataSource.java:688)
> Having run this throught a debugger and had a brief look at the code it seems
> to me there is a race condition of sorts.
> The MemoryManagedDataSource that provides the InputStream has been marked as
> deleted by the finalize method of AttachmentPart.
> So basically if the client doesn't read off the attachment fast enough then
> the writer will have finished and the AttachmentPart gets finalized and blam,
> you've got a deleted MemoryManagedDataSource.
> I'm not sure what the best fix is. Perhaps the deletion should actually be
> some reference count rather than a simple boolean. That way the
> MemoryManagedDataSource gets deleted once all the writers and readers are
> done? Although perhaps then there would be an issue if the client was very
> slow to even open the attachment?
