<h1>What's new in dCache 5.1<br/>
<small>Release notes</small></h1>
</div>
## Highlights
The 5.1 series of dCache focuses on new data transfer features.
It introduces 3rd-party copy capabilities to the xrootd protocol.
FTP doors can now support anonymous-FTP logins, and explicit TLS
encrypted control channel (FTPS).
gPlazma has gained support for SciToken authentication as well as improved OpenID Connect support.
Pools can now send the full set of inotify events through SSE.
Pool manager can create dynamic pool groups based on defined tags.
## Incompatibilities
* The Kafka configuration was moved from dcache.properties to a dedicated kafka.properties file.
## Acknowledgments
Once again, we are grateful for code and documentation contributions from contributors outside of our core team.
Onno Zweers provided many helpful corrections to the documentation.
Lea Morschel also provided documentation and code refinements.
Other contributions originated from a lecture at HTW Berlin; many thanks to Jonas Grabber, "tabea", "Co" and "xpinkyx" for their contributions.
## Release 5.1.26
### dcache-xrootd
The version is upgrated to xrootd4j 3.5.7 with lossen username validation, so that
usernames like `foo.1234:56` are no longer rejected.
The current release fixed java.lang.IllegalStateException: ChecksumChannel must not be written to after getChecksums.
TPC client first will be shut down when
the pool netty channel goes inactive.

## Release 5.1.25
### pool
The unix xrootd tpc security plugin was included in order to
enable the dCache TPC client to use a dCache pool as source
when signed hash verification is on. However, this is now fixed and
no special configuration necessary for organizations (like Tier 1)
needing to communicate with EOS.

## Release 5.1.24
### frontend
When frontend is run in a core domain and there is
no history service reachable, the retry on no route
to cell ends up spamming the message queues. This is now fixed.
### xrootd
The current release fixed compatible level security for sigver.
The xrootd client has a command-line option, `--path`, which
tells the server to create missing directories. This option
is included in two-party copy, but setting it for TPC has
no effect. TPCs which wish to write to dCache (as destination)
to a non-existent subdirectory fail. This is now fixed and dCache no longer fails in these cases.

## Release 5.1.23
### dcache
QOS migration policy engine was raising JVM error when no tape pool found.
This is now fixed and the normal behavior is that HTTP error code reported back with `No HSM pool found`.
### frontend
The current release improved error responses and they are more specific now.
The current release fixed the NPE stack trace arised because the pool
data could be sent with a default sweeper data
object.

## Release 5.1.12
### 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 5.1.10
### 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 5.1.8
### nfs
NPE on "show transfers" command is now fixed.
### webdav
The current release fixed CORS for WebDAV doors that do not allow anonymous
access; in particular, to support dCacheView uploading
and downloading files with such authentication-required
WebDAV doors.

## Release 5.1.7
### 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.
### nfs
The NFS door now correctly handles situations where newly created read-only
files could occasionally not be written into:
f = os.open('test.txt', os.O_WRONLY|os.O_CREAT, 0400)
os.write(f,"Hello pNFS!")
os.fsync(f)
os.close(f)
will now succeed.
### 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 5.1.6
### many
The `dcache pool ls` command now provides correct output even if the pool is
defined with a single-digit number of bytes.

## Release 5.1.5
### 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.

## Release 5.1.4
### 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
setting a timeout for xrootd 3rd party copy operations. This can also be changed through
the new admin command `xrootd set server response timeout`.
