### Highlights
- New consistent naming scheme for configuration properties.
- Billing plots are now generated by httpd, which implies
that the billing service and the httpd service are allowed to
run on separate machines.
- We added the possibility to specify multiple poolgroups as
target poolgroups in the migration module.
- Chimera now supports the set-gid bit on directories to
allow the group owner of new entries to be inherited from the
directory.
- We added a possibility for the pool to callout to an
external health check script.
- Pools now implement rate-limiting in the 'sweeper purge'
command to avoid pnfsmanager overload caused by high deletion
rate.
- Support for htpasswd files.
- SRM has been extensively cleaned up.
## Upgrade Instructions
### Incompatibility
**The naming scheme for the configuration properties has
changed. Please read the release notes for <a href="#0">dCache
2.7.0</a> very carefully and follow the instructions.**
### Compatibility
All dCache 2.7-release services are *not* compatible with any 2.5 (or
earlier) dCache service.
All dCache 2.7-release services are compatible with any dCache 2.6
pool services, but are *not* compatible with any dCache 2.6 non-pool
services.
All dCache 2.7-release services are compatible with any other dCache
2.7-release service.
**Important:** As a special case, if dCache is configured to allow NFS
access then 2.7-release pools must run v2.7.6 or newer. Compatibility
with 2.6-release pools requires the nfs service be v2.7.6 or newer.
## Release 2.7.36
### Changes affecting multiple services
dCache uses a standard format to monitor the performance of various
components: in the srm door to record how quickly SRM requests are
processed (`print srm counters` command), the generic cell message
monitoring (`monitoring info` command), and pnfsmanager service (the
"Statistics" section in `info`). This release fixes a rounding error
that prevents these statistics from including long-lived requests.
### pinmanager
The pinmanager service has the `ls` command that allows the admin to
limit the results to a specific pin or all pins against some PNFS-ID.
This release fixes listing by pin id.
### srm
This release fixes the srm service so it cancels corresponding
pinmanager requests when an SRM client aborts a bring-online request.

## Release 2.7.34
### pool
When a client reads a file, the pool reads blocks of data from the
local filesystem. When reading such a block, the pool could receive
fewer bytes than requested. Previously, the pool assumed that this
only happens when the end-of-file is reached; however, this is not
guaranteed. Should this assumption be violated then the data sent to
the client will be corrupt. In practise, the pool's assumption is
true for Linux and local filesystems; however, the code has been
updated to remove this theoretical cause of corruption.

## Release 2.7.33
### pool
When attempting to upgrade non-precious and non-cached files (e.g. a
file marked `broken`), the receiving end of the migration module would
answer twice: first (correctly) with a failure and then (incorrectly)
with a success. This is now fixed.

## Release 2.7.32
### Changes affecting multiple services
Various scripts, including the `dcache` command, invoke the `java`
command with a list of directories in which Java should look for
support libraries. Previously, the current working directory was
(mistakenly) included in that list. This could lead to odd behaviour;
one particular example is running a `dcache database` command from the
`/etc/dcache` directory. This release fixes this problem by excluding
the current directory.
When there is some problem in the communication between domains and
error message is logged. Previously the explanation for the problem
was logged as "null". With this release, a more descriptive
explanation is provided.

## Release 2.7.31
### Changes affecting multiple services
This patch fixes a race condition in Chimera that affects the nfs door
and the pnfsmanager service. The effect is that, if two clients
attempt to delete the same target (a file, link or directory) at the
same time then the nlink count for the parent directory is decreased
twice. "At the same time" means within the time taken to process the
deletion; this is instance-specific but should be much less than 1 ms
for well-configured systems. Sites can repare any incorrect nlinks
with the following SQL:
UPDATE t_inodes SET inlink = (
SELECT COUNT(*) FROM t_dirs WHERE t_inodes.ipnfsid = t_dirs.iparent
) WHERE itype = 16384;
This is safe to run on a running production instance, but may take
some time and will affect dCache's responsiveness while running.
### gplazma
The description for how to migrate away from using the forbidden
`useGPlazmaAuthorizationModule` and `useGPlazmaAuthorizationCell`
properties had caused confusion. The description has now been updated
to be more explicit.
### httpd
Fix filtering boxes and sorting on Pool Admin, Pool Usage, Poolgroups,
Space Tokens and Tape Transfer Queue.
### srm
Uploading a file with SRM involves three steps: preparing for the
upload (`srmPrepareToPut`), uploading the file, marking the upload
finished (`srmPutDone`). The third step can fail but previously the
response from dCache is always `Upload failed.`. With this release, a
meaningful error message is returned.

## Release 2.7.30
### ftp
Fix default value for `ftp.authz.readonly` for plain (unencrypted)
doors. This restores the default value to the dCache v2.6 default
value of `true`.
The response from the plain (unencrypted) ftp door if the user
specifies the wrong password is badly formed. Althogh it is possible
that some clients are robust against such incorrect responses, with
this release the ftp door responds correctly.
### webdav
Fixes a bug where, if a double-slash is present, all parts of the path
leading up to the double-slash are ignored; for example, with the bug,
a path like `/a/b//c/d` is handled as if `/c/d` was specified. With
this release, double-slashes are treated like single slashes; the
above example is handled as if `/a/b/c/d` was specified.

## Release 2.7.29
### Changes affecting multiple services
Previously releases of dCache claimed to support Java-8; however, this
is not true. For Java-8 support, sites must upgrade to dCache v2.10
or newer.
### httpd
Fix two minor issues when authenticating with the webadmin interface:
"unauthorised access" and being redirected to the home page. The
unauthorised access error can occur when selecting "Login" under the
bird logo (top right corner); this is now fixed. The redirection
problem occurs when selecting a tab that requires administrative
privileges while not logged in; this redirects the browser to the
login page. Previously, after a successful login, the browser was
redirected to the home page. Now the browser is redirected to the
selected tab.
### webdav
A previous bug-fix release fixed how dCache responds when the client
attempts to `DELETE` a non-existent file. Unfortunately, this
triggered a different problem where such activity results in a
stack-trace that starts `java.lang.ClassCastException:
java.lang.String cannot be cast to javax.security.auth.Subject`. This
second problem is now fixed.

## Release 2.7.28
### info-provider
In previous releases, the info-provider assumed the broker domain is
`dCacheDomain`. This assumption has been removed.
### nfs
Update to nfs4j v0.7.9. Avoid errors when the door is heavily loaded
and the client closes a file. Avoid potential deadlock under the same
circumstances. Add the `pnfs` and `nopnfs` options for controlling
whether PNFS is supported. Fix parsing the exports when a host is
mentioned multiple times. Note that `localhost` must now have an
explicit entry in the exports file.
### pool
A recent release fixed a bug that caused
`pool.mover.ftp.allow-incoming-connections` to be ignored. Fixing
that bug revealed another that caused the property to have the
opposite effect. This is now fixed.
### webdav
Although dCache behaves correctly if the client interrupts a proxied
transfer; however, this is logged as a bug. This is now fixed.

## Release 2.7.27
### Changes affecting multiple services
Although dCache system configuration property names do not contain
spaces, it is possible to define such properties. Previously, doing
so breaks the `dcache` command. This is now fixed.
### dcap
Fix regression against v2.6 and earlier dCache in how gsidcap doors
are known to SRM and how they are published in BDII/GLUE.
### pool
The `pool.mover.ftp.allow-incoming-connections` property had no
effect. This is now fixed.
### srm
Previously, if the SRM client requests listing a directory, specifies
a non-zero offset and does not limit the response size then dCache
would fail this request with an IllegalArgumentException. This is now
fixed.
### webdav
With the recent upgrade of the Milton library some new behaviour was
introduced. One example is that, under certain circumstances (and to
support certain clients) the Milton library returns a `401` (not
authorised) when attempting to delete a non-existing file.
Unfortunately, this change then broke ATLAS clients. This patch
updates dCache so it returns `404` (not found) under these
circumstances.
Fix the response when a client requests a byte-range beyond the end of
a file. This is necessary for compatibly with ARC clients.

## Release 2.7.26
### nfs
Under heavy load, if the nfs door is restarted, the new door may
receive response messages from requests send by the previous door. In
previous versions of dCache, this situation triggered a stack-trace.
This is now fixed.
### pool
The NFS specification allows the server to specify multiple addresses
when telling the client where to connect; for example, specifying both
an IPv4 and an IPv6 address, or both addresses for multi-homed
machines. This requires the client to choose the appropriate
interface. For Scientific Linux 6, the kernel client will always use
the first supplied address in the list and fail if it cannot access
the pool with that address. With this release, pools will order the
list, using heuristics to select which IPv4 address is "correct" and
list it first.
### poolmanager
With previous dCache versions, the WAAS selection algorithm had a bug
where it could (mistakenly) consider pools full if all pools had very
fresh files. This is fixed with this release.
### webdav
Upgrade to Milton v2.6. This fixes the buffering problem where a
proxied vector read request results in the entire file being written
to a `tmp` directory and not deleted. With this release, requests for
100 kiB or less data result in no data being written to disk; requests
for more than 100 kiB are still written to disk, but only the data
needed to satisfy the request is stored and the file is deleted once
the response has been sent. Some issues persist: data isn't deleted
if there is a failure sending it to the client and the whole file is
requested from the pool.

## Release 2.7.25
### httpd
dCache versions including and after 2.11.0, 2.10.9, 2.9.12, 2.8.16,
2.7.21 and 2.6.36 required sites to delete existing RRD files when
upgrading; i.e., run the command `rm -f /var/lib/dcache/plots/*.rrd`
when the domain hosting the `httpd` service is stopped. This release
reverts that change, but requires sites that have already upgraded to
repeat the `rm` command. Sites upgrading from an earlier dCache
version do not need to delete anything.
### nfs
Protect against a `NullPointerException` if the client attempts to
read the contents of a file's level where that level exists in the
database but contains a Nil value. This does not happen under normal
circumstances.
### pool
The Berkeley DB, which may be used to store file metadata on the pool,
does not like being interrupted. The pool tries hard to avoid
interrupting reading or writing; this release fixes one place that
slipped through.

## Release 2.7.24
### httpd
In previous versions of dCache, the webadmin war file is automatically
unpacked. This has been problematic as a dCache upgrade did not
always trigger updating the unpacked webadmin, resulting in dCache
running the older webadmin. With this release, dCache no longer
unpacks the war file; the `webadminWarunpackdir` and
`httpd.container.webapps.tmp-dir` properties are now obsolete.

### Changes affecting multiple services
A bug was discovered that resulted in the nlink count becoming
negative. While wrong, this had a knock-on effect that prevented
pnfsmanager and nfs services from listing the affected directory.
With this release, directory listing are robust against such problems.
### alarms
Fix alarm definition that triggers when the pool discovers a file with
the wrong checksum. Previously it mistakenly triggered if an upload
was incomplete.
### nfs
Update nfs4j to v0.7.8. This brings some small performance benefits
when listing a directory and for reading data through NFS v3.
Fix bug where, when a client read activity is proxied, the
corresponding dcap mover wasn't removed if client didn't wait for the
queued mover to start. Previously, such movers would accumulate on
the pool.
### pnfsmanager
Prevent attempts to remove the `.` and `..` directories.
### webadmin
Display the command's output in the cell admin page to use a monospace
font.
Remove a javascript error due to missing clojure dependency.

## Release 2.7.22
### Fixes affecting multiple services
Update `dcache check-config` to print an error if site-local
configuration contains scoped properties: one that contain a '/'
character.
### httpd
Fix pool queue plots in webadmin.
### nfs
Performance improvements.
### pnfsmanager
Fix the message reported when moving (or renaming) a file or directory
and certain problems were found: the destination directory isn't a
directory, the source doesn't exist, or overwriting with different
types (e.g., overwriting a directory with a file).
### poolmanager
If a site using WAAS specifies too large a Space Cost Factor then the
algorithm used for write pool selection breaks down, logging
"Unreachable statement." Starting with this release, a warning is
logged indicating the cause of the problem.

## Release 2.7.21
### Fixes affecting multiple services
Running the `eval` admin command so it returns a non-zero return-code
would respond indicating that a bug had been found. This has been
fixed.
An named environment may be executed and can contain a reference to
itself. If this recursion is unchecked, eventually memory is
exhausted and the domain would restart. Now an error is logged and the
domain is not killed.
Previously, some exceptions were logged with the wrong cell context or
without any context. This has been fixed.
### billing
Billing records issued by doors never included the file's size. This
is now fixed for all doors except NFS.
### gplazma
The xacml plugin now supports the gums server returning GID values.
### pool
Fix internal copying of files (triggered by the SRM `copy` command) so
they respect the LAN port range.
Fix migration module's random pool selection so that it does not
select pools that are full.
Fix NullPointerException triggered when using migration module's
proportional pool selection and all pools are full.
The `rep ls` command can calculate per-storage-class statistics. This
release fixes a problem where files without a storage-info would
trigger an IllegalStateException when calculating these statistics.
Fix sweeping of files without a storage-info. Previously an
IllegalStateException was thrown; this could be triggered by the admin
interface or by the sweeper.
Fix a problem where the pool would register free space before actually
deleting the file from the file system; for a brief moment, the pool
would appear to have more free space that is actually available.
Periodically, pools check that dCache's internal accounting of total
and free capacity does not exceed the OS supplied values for the
partition (i.e., the output from the `df` command); if they do then
the dCache internal accounting is adjusted to match. The dCache.org
team have observed that, after a file is deleted, some seconds may
elapse before the corresponding extra free capacity is reported by the
OS. To protect pools from this effect, the total and free capacity
check is suppressed for 60 seconds after a file was deleted.
### srm
Fix the srm service's admin interface `ls` command so that listed jobs
can optionally include only those that have failed, have completed or
were cancelled.
### webadmin
Webadmin periodically creates billing graphs by querying the billing
service for the information it needs. Previously, if this query
failed (e.g., the billing service was restarted or failed to start
first) then no further billing graphs are generated and a domain
restart is needed. As a result of this work, the properties
`poolqplots.refresh-interval`, `poolqplots.refresh-interval-unit`,
`httpd.plots.pool-queue.refresh` and
`httpd.plots.pool-queue.refresh.unit` are no longer supported. The
`httpd.plots.pool-queue.min-time-step` and
`httpd.plots.pool-queue.min-time-step.unit` properties now also cover
this configuration.

## Release 2.7.20
### Fixes affecting multiple services
The nfs and srm both cache replies from gPlazma to increase the speed
of authenticating and identifying the user. Previously transient
errors when communicating with gPlazma were also cached, delaying the
recovery time from such errors. Now, such errors are not cached.
Update the comments within the configuration property files to reflect
the new configuration property names.
Fix OpenMQ communications to use new configuration property names.
### dcap
Fix opening a file when space-manager enabled.
### nfs
No longer trigger an NullPointerException when opening the
`.(parent)()` dot-command file in Chimera's root directory.
