## Executive summary
Highlights from this release:
- Significant performance and storage space improvements in Chimera.
- Almost all certificiate handling code has been ported to the EMI
CANL library rather than JGlobus. Provides OCSP support and
EUGRIDPMA name space support.
- Concurrent request processing in gPlazma.
- Pool group patterns in admin shell.
- Improved UberFTP support.
- WebDAV door can report file locality.
- Fair share scheduling for SRM transfers.
- SRM database managed by liquibase.
- Configurable kXR_Qconfig support for xrootd.
## Incompatibilities
- Strict RFC 2818 host name checking in SRM/HTTP clients - this in
particular affects server side srmCopy and WebDAV COPY. It is
expected that this will break with server side copy to/from some
WLCG sites. Globus Toolkit enables the same strict mode by default
by the end of the year, so we expect the affected sites to get new
host certificates soon. Additionally, server side copy is not used
much, so it is likely not be a big issue for dCache.
- Significant schema changes in Chimera. Upon upgrade the schema will
be updated, which may take a while for large sites. To downgrade,
the schema changes have to be rolled back with the appropriate
command in dCache *before* downgrading dCache.
- PnfsManager now uses a single request queue. This could possibly
affected third-party monitoring scripts that scrape the info output.
- All forbidden and obsolete properties in 2.13 have been removed and
all deprecated properties in 2.13 have been marked obsolete.
- RC4 ciphers are banned by default and the option to ban Diffie
Hellman key exchange if broken has been removed.
- gPlazma now instantiates plugins separately for every use in
gplazma.conf. This means that the configuration has to be specified
for all lines, not just the first. This provides the flexibility to
use the same plugin several times with different configurations.
- The WebDAV door enables BASIC authentication by default over HTTPS.
- Pools always compute checksums on the fly and the `ontransfer`
checksum policy has been dropped.
- The SRM by default uses a fair share scheduler for scheduling
transfers. Thus the observed behaviour under load may have changed.
- SRM 1 support is deprecated and disabled by default.
- SRM scheduler states have been simplified. Third party monitoring
scripts that track request states may have to be updated.
- SRM no longer retries SRM requests internally. Failures are
propagated to the client to provide fail-fast behaviour.
- SRM no longer resolves host names in SURLs when determining whether
they are local to this dCache instance or not. In particular, this
may affect sites that use DNS aliases.
- The SRM database schema is now managed by liquibase and the schema
is updated upon upgrade. To downgrade, the schema changes have to
be rolled back with the appropriate command in dCache *before*
downgrading dCache. As a consequence, user information for existing
SRM requests will be lost from the database. Third party scripts
that access the SRM database directly may have to be updated.
## Release 2.14.51
### admin
While `migration move` tasks on pools were working correctly, for `migration info` command an error occurred,
that the current user (root) wasn't allowed to execute anything (due to missing ACLs). This is now fixed.

## Release 2.14.50
### httpd
The "Disk Space Usage" webpage (`/usageInfo`) contains a table showing
information about each pool in the dCache cluster. The "Layout"
column showed the capacity usage graphically, with different colours
showing how much of that pool's capacity is being used for different
tasks. This release fixes the Layout heading to describe a previously
undocumented colour.

If the communication between a pool and PnfsManager times out, the error message is not well suited to diagnosing the problem:
`Failed to instantiate mover due to unsupported checksum type: Request to [>PnfsManager@local] timed out.` The checksum type is
not playing an important role here. Hence, this patch updates the error message.

## Release 2.14.48
### webdav
A recent update, commit 5abc0e1c, improved the behaviour of the Milton WebDAV libraries if an IOException occurs
during an upload. That patch, unfortunately, did not address all issues, and when non-spec-conformant clients
are used against dCache, stacktraces can be triggered.
This patch corrects that behaviour. Also, in case of errors, the error code returned in case of any problems
was changed from 400 to 500, which should signal cliens that they are free to retry the transfer after a timeout.

## Release 2.14.47
### Changes affecting multiple services
The version of the PostgreSQL driver used by dCache internally was brought up to 9.4.1212. This fixes the issue described in [liquibase bug 2939](https://liquibase.jira.com/browse/CORE-2939).

## Release 2.14.45
### chimera
The current release fixed database query for storing multiple checksums for a file.
### ftp
The Socket `read` method may return zero to indicate that no bytes were
read. Although this is not an error, such occurances will result
in a transfer failing.
This is now fixed.

## Release 2.14.43
### ftp
The current release improves compatibility between dCache FTP client and Globus GridFTP server.
### srm
During an ATLAS stress-test of tape recalls, it was discovered that
various sites had relatively short request lifetimes. However, the SRM
spec provides the opportunity for the server to inform the client (FTS,
in this case) of what lifetime a request actually has.
The current release includes the requests remaining lifetime in the response from the server.
The current release improves the documentation to help Admins to have a better understanding how to configure dCache correctly.

## Release 2.14.42
### xrootd
In https://github.com/xrootd/xrootd/issues/459, it became apparent that dCache could improve xrdcp compatibility by sending
checksum information in lower case. This release contains this change, which should improve xrootd operations.

Connections of non-DCAP clients to a dCache no longer result in stack-traces in the logs.

## Release 2.14.37
### Changes affecting multiple services
Internal notification processing between cleaners and Pin Manager, Replica Manager and Space Manager was improved and runs quicker now.
### admin
A bug in the Admin service that caused it to not detect certain error replies
from other components was fixed.
### billing
If a dCache instance was shut down while the billing service was in the middle of a refresh,
an exception was logged and shutdown was delayed. A change in exception handling fixes this rare
scenario, ensuring a quick shutdown and no unnecessary log entries.
### dcap
This release makes it possible for admins to ban outdated, problematic versions of dcap clients.
Some old client versions contain a bug that causes the
client to make unsatisfiable requests to a pool with no way for dCache
to reject the request: the client will simply retry.
The client version limits are exposed using the new configuration property `dcap.limits.client-version`.
The default is to allow all dcap client versions, unchanged from the previous behaviour.
This release fixes a regression through which Kerberos dcap would not work for host principals containing a '-' character. GSI dcap was not affected.
### doors
Fixed a bug in the lb set tags command in doors that prevented setting
an empty list of tags.
### pool
A bug that caused non-critical stack traces to be logged on the pool after
stage or deletion failure from nearline storage has been fixed.

## Release 2.14.35
### billing
Fixed a problem in the output of the `dcache billing` command using
JSON or YAML when the billing format includes a custom date format.
### dcap
Add support for the dcap client supplying additional version
information.
### gplazma
Fix `explain login` and `test login` commands so they are able to test
logging in with username and password.
Add examples to `explain login` command help. Our thanks to Onno
Zweers for this change.
### httpd
Fix regression in the `transfers.txt` output format.
Update the transfers.html page so it no longer includes `<unknown>`
for default/unknown protocols. With this version of dCache, these are
represented by a `?` character. The webadmin page is updated to give
consistent output.
### scripts
Fix the billing indexer to ignore the `format` string, if present.

## Release 2.14.34
### commons
If dCache's internal ShellApplication framework detects a critical behaviour
that might indicate a bug in the application, error messages now include
an explicit request to send a mail to the developers and more relevant
information for assessing and reproducing the situation.
### gplazma2
This release fixes a small bug in GPlazma which inappropriately
tried to handle non-DN subjects in x509 certificates.
These will usually fail in gPlazma anyway, but the reported error
was confusing.
### srm
Handling of DNS names without trailing dots in certificates has been made more robust and universal.

## Release 2.14.33
### cells
In rare cases, an interrupt needed to cleanly shut down the location manager connector would not arrive. This issue was corrected, ensuring more reliable behaviour on cell shutdown.
Fixed a problem in which threads could inappropriately be created as daemon threads,
causing problems in killing those threads when the cell shuts down.

## Release 2.14.32
### commons
The \s admin command uses the toString method to serialise the requested
so that the remote cell may correctly parse it. This did not always
work: '=' characters in arguments were escaped but not unescaped;
arguments that start with a '-' character were not escaped; empty words
were lost. In the current release this is fixed and \s command works as expected.
### dcache
The current release fixes a regression in which the exit code of check-config would
always be zero even when errors were detected.

## Release 2.14.31
### alarms
Alarm email notifications are now sent only on the first occurrence
of given alarm (i.e., for that alarm instance's unique ID).
If an alarm has been closed and not deleted,
but then occurs again, the counter for receiving that alarm
is now reset to 1, in order to treat this as a new (set of)
occurrences, and to guarantee a new notification will be sent.
### webadmin
Due to an implementation detail in a library used for the webadmin pages, filtering
tables was a bit unintuitive until now: A filter that was set in a certain table column would
reappear on tables in other browser windows if they had similar columns.
This behaviour was corrected, and tables on different pages exposed simultaneously in different
browser tabs are now filtered independently. However, the fix also has the side effect that
now with page reloads and form submissions the filters are cleared. Any commands, however, will
always be issued correctly.
Filtering rows in webadmin tables could occasionally lead to unintuitive behaviour with regard to selections:
Filtering a table and hiding rows may be included in a "select all" or "deselect all" operation.
This was fixed, and selection/Deselection of hidden rows is now prevented.
Issues with filter boxes disappearing or filters resetting have been solved by disabling
AJAX auto refresh for the affected pages.

## Release 2.14.30
### chimera
Chimera occasionally suffered from (operationally irrelevant) IllegalStateExceptions. Those are now avoided.
### doors
Doors could get stuck temporarily if a file was deleted during pool selection. This has been fixed, and in such cases, transfers are now aborted properly.

## Release 2.14.29
### billing
When using the `dcache billing` command with a non-default date format in the billing file, an unneccessary stack trace was printed. This has been corrected.
### srm
The SRM should periodically (by default every 10 minutes) delete obsolete historic data (older than 10 days by default) from the database. For cases where there are problems with that process, error logging and robustness against temporary database problems have been improved.
### webadmin
The Wicket library used by dCache internally issued warnings about upcoming naming changes. Those cluttered the log files, and are silenced from the current version on.

## Release 2.14.28
### ftp
The Apache Commons FtpClient can issue the LIST command with the
non-standard `-a` option. Which was causing dCache to switch
output format from the long (`ls -l`-like) to the short (`ls`-like)
response. This is fixed now and dCache is more compatible with Apache Commons FtpClient.

## Release 2.14.27
### cells
If the `create` command in CellShell fails because of unreadable setup files, it throws an IOException. This was incorrectly reported as a bug. Reporting has been corrected now.
In rare cases, active transfers would show up with an incorrect state in the active transfers page of the admin backend. This was fixed, so that ransfers which are staging from non-DCAP doors are correctly indicated (in yellow) on the active transfers page, instead of showing up as "No Mover found" (in red).
### common
If there is an IOException when trying to read a setup file, the corresponding file name is now listed in the error message.
### poolmanager
An issue with PoolManager prevented it from delivering correct cost estimates. This was fixed, resulting in improved estimations of pool load.
