Subject [jira] [Commented] (HDFS-4354) Create DomainSocket and DomainPeer and associated unit tests
Date Thu, 03 Jan 2013 23:26:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13543407#comment-13543407
] 

Todd Lipcon commented on HDFS-4354:
-----------------------------------

I reviewed just the new parts in this patch since HDFS-4353. Also worth noting that there
were a few rounds done on this code earlier in https://reviews.apache.org/r/8554/. So, only
a few small comments here:

----

{code}
+  /**
+   * Return true only if UNIX domain sockets are available.
+   */
+  public static String getLoadingFailureReason() {
{code}

Javadoc is mistaken

----
{code}
+    assert newCount >= 0;
{code}
Don't you mean {{newCount & ~STATUS_CLOSED_MASK}}?

Might be nice to define {{private static final int STATUS_REFCOUNT_MASK = ~STATUS_CLOSED_MASK}}
as well.

---
Otherwise looks pretty good, but I'll wait for a broken-out patch before giving a +1.

> Create {{DomainSocket}}, a JNI class which provides UNIX domain sockets functionality
in Java.  Also create {{DomainPeer}}, {{DomainPeerServer}}.  This change also adds a unit
test as well as {{TemporarySocketDirectory}}.
> Finally, this change adds a few C utility methods for handling JNI exceptions, such as
{{newException}}.
