<h1>What's new in dCache 4.2<br/>
<small>Release notes</small></h1>
</div>
## Highlights
This release ships with dCache-View 1.4+ which provides a new version of the
familiar admin pages. Currently, access to these new pages requires the user
to be authorized (and to assert) the admin role. The pages are only fully
populated with their respective data when, in addition to the frontend service,
the alarms and history services are running, and the billing service has
the database backend enabled.
With this release, dCache-View completely replaces the (Wicket-based) “webadmin”
interface, which is no longer available on ports 2288 and 8440. (The
old static pages at http://<host>:2288/old are, on the other hand, still available,
but these, too, will eventually be removed in a future release.)
## Incompatibilities
Some changes
([a11ec8d76b](https://github.com/dCache/dcache/commit/a11ec8d76b549e3e1de948e2848d73d86725029e),
[887d8d5738](https://github.com/dCache/dcache/commit/887d8d5738c6e2c554af8cd14e9ff8028b5e0573) and
[2ff49b600c](https://github.com/dCache/dcache/commit/2ff49b600c5f7e24148596a8a70f26af0bdd12ea)
) in the current release require that Pool Manager, Space Manager and Door
instances must be updated to 4.2 at the same time. For users that wish to do incremental
updates, pools may remain at 4.1 during that update.
## Acknowledgments
The dCache team thanks Christoph Anton Mitterer, Martin Johnki, Onno Zweers and Johannes Thurn
for their pull requests and contributions.

## Release 4.2.48
### srm
The current release fixed a problem resulting in high CPU use in SrmManager if clients are
attempting to pin a file and PinManager is unavailable.
A regression fixed where SrmManager will reject all QUEUED jobs and
INPROGRESS BringOnline requests on restart, if there are no SRM doors
running when SrmManager starts.

## Release 4.2.46
### pool
Pool health-check log messages now include the pool's name.
### webdav
On an unsuccessful HTTP-TPC pull request, dCache will delete the file.
If this deletion did not work then an error was logged. This is fixed now and
failures to delete the incomplete file from a failed HTTP-TPC pull
request, where the incomplete file has been deleted by some other means
are now logged at DEBUG level, rather than WARN level.
### xrootd
The current release refited checksum handling after xrootd4j bug fix.

## Release 4.2.44
### Changes affecting multiple services
The Apache Commons Compress library used in dCache was updated to version 1.19.
A rare deadlock situation in the Chimera database was eliminated. In cases
where, within the same directory, concurrent mkdir and rmdir events happened,
transactions within the database could deadlock. This would be indicated by the message
ERROR: deadlock detected
in the logs.
### pool
There were reports of extraordinarily high CPU usage on pool nodes with a large
number of cached files. Through an optimization of the `sweeper`, CPU usage
was reduced significantly.
### xrootd
This release fixes a vulnerability in dCache's XRootD protocol implementation.
We recommend that all sites update their XRootD doors.
Details will be made available through EGI Security and, in a week's time, through an
update to these release notes.

## Release 4.2.42
### srm
A new user community requires the srm tools to be able to handle
very large file listings. During preliminary tests, OutOfMemory
errors from the srmls tool were observed. This is now fixed and
srm can now support operations on very large file lists
without running out of memory.
### webdav
The current release added allow header to list of response headers for OPTION method
request.

## Release 4.2.39
### chimera
The shell infrastructure supports commands being given interactively, on
the commandline (e.g., 'chimera mkdir /path/to/dir') and from stdin
(e.g., 'echo "mkdir /path/to/dir" | chimera'). `chimera` now supports the latter
case and properly shows command output when invoked in that fashion.
### frontend
This release updates dCache View to 1.5.5.
### webdav
A client may issue a PUT request that targets an existing collection
resource; i.e., attempt to write a file as a path that is a directory.
dCache, until now, responded with an incorrect status code of 500. This release
changes the status code for this operation to 405 (Method not allowed),
thus keeping closer to RFC 4918.
### xrootd
This release improves compatibility with the xrdcp client in versions \>4.9
by responding correctly to query strings requesting a specific checksum type.

## Release 4.2.37
### frontend
This release updates the dCache View web GUI to version 1.5.4.
### ftp
HAProxy can probe endpoints to discover if
they are still alive.
The FTP door has an optimisation that detects such probes and does not
create the FTP command interpreter, since the FTP client (the HA-Proxy
instance) is calling on behalf of itself, and will not issue any FTP
requests.
This release fixes a regression that would cause erroneous
NullPointerExceptions when FTP doors were probed by HAProxy.
### pool
The default value for the xrootd Third-Party Copying server response timeout,
`pool.mover.xrootd.tpc-server-response-timeout`, was increased from 2 to 30 seconds
to provide more robust behaviour in the face of high loads and network congestion.
### transfermanager
Error messages like the WebDAV door's
`Failed to fetch information for progress marker: failed to query pool: (0) Job not found : Job-1`
where the TransferManager is unable to discover the
current status of the pool mover now include the pool's name,
which should make debugging easier.

### Changes affecting multiple services
This release includes an updated Jetty library, with the update adressing
CVE-2019-10247.
This release includes an updated Jetty library, with the update adressing
CVE-2019-10247.
### dcap
The Kafka messaging implementation in the dcap service has been made more robust,
fixing issue [#4831](https://github.com/dCache/dcache/issues/4831).
### frontend
Periodic activity associated with the frontend door is now logged with the
door's cell name. Such messages will also appear in the door's
pinboard.
### nfs
Periodic activity associated with the NFS door is now logged with the
door's cell name. Such messages will also appear in the door's
pinboard.
### pool
Attempting to start a full checksum scan (with `csm check *`) while an
existing scan is still running is no longer reported as a bug.
Pool start-up logging now includes the corresponding pool cell name.
An internal timing check was updated, which should result in more robust pool
behaviour. There should be no user-visible impact.
### webdav
Periodic activity associated with the WebDAV door is now logged with the
door's cell name. Such messages will also appear in the door's
pinboard.
### xrootd
A new configuration property, `pool.mover.xrootd.tpc-server-response-timeout`, allows

## Release 4.2.34
### alarms
To ease troubleshooting, the POOL_DEAD alarm message now includes the pool name.
### pinmanager
A bug was fixed where PinManager's `bulk ls` admin command yielded a
NullPointerException if the optional argument was omitted.
A typo prevented the error message "Remote connection failure while unpinning..." from
appearing completely and correctly in the logs. The error message string now contains
the message string of the underlying Exception, hopefully providing helpful details for
troubleshooting.
### pool
A regression that prevented a replica's last access time from being updated was fixed.
A regression that prevented a replica's position in the LRU queue for garbage collection from being updated was fixed.
### webdav
Users asserting the "admin" role would occasionally receive
NullPointerExceptions when trying to transfer files through
WebDAV. This release fixes that issue.

## Release 4.2.33
### Changes affecting multiple services
Stage request from unknown locations resulted in NPE in dcap and pinmanager services.
this is now fixed and using `dccp` to stage a file should work even if the location is unknown. '--'
### frontend
A client that disconnects and quickly reconnects could had triggered the following NPE, this is now fixed.
### resilience
The current release fixed race condition on replica state and no `inaccessible file errors` occures for a newly written file.

## Release 4.2.32
### frontend
The destroy sequence for a channel failed to obtain the Channel
monitor. This could result in concurrent changes to the Channel's
state and incomplete Channel shutdown. This is now fixed and the shutdown sequence of a channel is more robust.
### pool
An unhelpful error message "Parameter `directory` is not a directory" is
replaced with one that provides information on which directory is
missing.
The pool no longer logs configuration or deployment problems that
prevent the pool from creating a mover as if that problem was a bug.
The current release fixed certain error cases, where a pool is unable to create a mover are no
longer logged as a bug in dCache.
### transfermanager
By default, the transfermanager will retry starting the mover ten times
before giving up on the pool. If we know that a pool doesn't support
this transfer type (for whatever reason), then this makes no sense. This is now fixed and a pool that does not support a particular transfer is not immediately
retried.
The current release fixed a NPE if transfer was cancelled.

### dcache
Jetty version is updated to 9.4.12.v20180830.
### nfs
nfs4j version is changed to 0.17.11 with fixed export table evaluation order.
### resilience
It is now possible to record resilience activity (on the receiving
end), which may prove useful in understanding
behaviour.
In rare circumstances dark removes can result in data loss by
removing of all replicas for a given file. The current release fixed the issue.
Pool operations now can successfully be restarted from the
command line after they have been shutdown, without
restarting resilience.
