[jira] Created: (DIRMINA-741) An autoexpandable IoBuffer becomes
non-autoexpandable after slicing
An autoexpandable IoBuffer becomes non-autoexpandable after slicing
-------------------------------------------------------------------
Key: DIRMINA-741
URL: https://issues.apache.org/jira/browse/DIRMINA-741
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-RC1, 2.0.0-M6
Reporter: Roger Kapsi
Hi,
an auto-expandable IoBuffer becomes non-auto-expandable in MINA 2.0 after slicing, duplicating...
{code:title=AbstractIoBuffer.java}
@Override
public final IoBuffer slice() {
recapacityAllowed = false;
return slice0();
}
{code}
{code}
@Test
public void autoExpand() {
IoBuffer buffer = IoBuffer.allocate(8, false);
buffer.setAutoExpand(true);
TestCase.assertTrue("Should AutoExpand", buffer.isAutoExpand());
IoBuffer slice = buffer.slice();
TestCase.assertTrue("Should AutoExpand", buffer.isAutoExpand());
TestCase.assertFalse("Should *NOT* AutoExpand", slice.isAutoExpand());
}
{code}
The documentation for IoBuffer says only Derived Buffers become non-auto-expandable.
{quote}
Derived buffers are the buffers which were created by duplicate(), slice(), or asReadOnlyBuffer(). They are useful especially when you broadcast the same messages to multiple IoSessions. Please note that the buffer derived from and its derived buffers are not both auto-expandable neither auto-shrinkable. Trying to call setAutoExpand(boolean) or setAutoShrink(boolean) with true parameter will raise an IllegalStateException.

[jira] Resolved: (DIRMINA-741) An autoexpandable IoBuffer becomes
non-autoexpandable after slicing

Emmanuel Lecharny resolved DIRMINA-741.
---------------------------------------
Resolution: Invalid
The IoBuffer doc specifically says :
"Please note that the *buffer derived from* and its derived buffers are not both auto-expandable neither auto-shrinkable"
Which makes sense, as both IoBuffer point to the same data. If you need to work on a auto-expanded buffer taken from an existing buffer, copy it to a new IoBuffer.
