full (suffixed) histogram name as the value for the name argument.
PHAB_ID=D640725
- com.twitter.server.util.JsonConverter is divided into two Json mappers, JsonConverter
and AdminJsonConverter. JsonConverter keeps the minimum configuration, for json mapping
to/from twitter-server admin endpoints, AdminJsonConverter is configured to do so.
PHAB_ID=D634550 - Json.scala and JsonConverter are merged, removed the Json.deserialize() methods.
PHAB_ID=D634550
- Revert to scala version 2.12.12 due to scoverage/sbt-scoverage#319
PHAB_ID=D635917 - Bump scala version to 2.12.13

PHAB_ID=D552357
- Check SecurityManager permissions in the ContentHandler to ensure that contention
snapshotting is allowed.
PHAB_ID=D531873
No Changes
- Make Lifecycle and Lifecycle.Warmup self-typed to TwitterServer. Lifecycle was previously
self-typed to c.t.app.App and Lifecycle.Warmup previously had no self-type restrictions. These
traits can now only be mixed into instances of TwitterServer. The Lifecycle.DetatchedWarmup
trait is introduced to allow users to transition to it, where they were previously extending
Lifecycle.Warmup without mixing into a TwitterServer. Lifecycle.DetatchedWarmup
is immediately deprecated and will be removed in a future release.
PHAB_ID=D507392
No Changes
- Make lookup of Admin LoggingHandler more resilient when multiple implementations are detected.
Now instead of perhaps using an incorrect handler the server will instead emit a lint rule violation
and not attempt to install a logging handler ensuring that only when a single LoggingHandler
is located that the functionality is enabled.
PHAB_ID=D484965
- Bump jackson version to 2.11.0.

Upgrade to jackson 2.9.10 and jackson-databind 2.9.10.1
PHAB_ID=D410846Multiple changes have happened around query parameter retrieval in order to remove duplicated functionality from Twitter Server that exists in Finagle. Users are encouraged to use finagle-http's Uri class within their own code to retrieve params.
PHAB_ID=D398387* The parse method of HttpUtils has been removed. * The protected getParams method of TwitterHandler has been removed. * The signature of the getGraceParam method of ShutdownHandler hasbeen changed to take a Request.
Add a disableAdminHttpServer property to the AdminHttpServer that can be used to prevent the AdminHttpServer from starting by default on a TwitterServer.
PHAB_ID=D397925The ResourceHandler companion object is no longer a JavaSingleton.
PHAB_ID=D399947Update ScalaTest to 3.0.8, and ScalaCheck to 1.14.0.
PHAB_ID=D408331
- Add initial support for JDK 11 compatibility.
PHAB_ID=D365075 - The endpoints section of the clients page has been fixed
to no longer render an incorrect html line break tag.
PHAB_ID=D391907
No Changes
- Changed com.twitter.server.AdminHttpServer.routes from a setter to getter, use it to get
all admin http server Routes. Use com.twitter.server.AdminHttpServer.addAdminRoute to add
a Route and com.twitter.server.AdminHttpServer.addAdminRoutes to add many Routes.
PHAB_ID=D354013
- Upgrade to Jackson 2.9.9.

name are added to the underlying com.twitter.app.App#flag com.twitter.app.Flags instance.
PHAB_ID=D314410
Remove deprecated uses of c.t.server.ShadowAdminServer.
PHAB_ID=D269149Mix in the c.t.finagle.DtabFlags to allow servers to append to the "base" c.t.finagle.Dtab delegation table. Users can now call c.t.finagle.DtabFlags#addDtabs() when they want to append the parsed Flag value to the Dtab.base delegation table. Users should note to only call this method _after_ Flag parsing has occurred (which is after init and before premain).
We also update the c.t.server.handler.DtabHandler to always return a proper JSON response of the currently configured c.t.finagle.Dtab.base.
PHAB_ID=D297596
- Change the /admin/histograms?h=...-style endpoints to return data in the same style as
/admin/histograms.json. This should make it easier to use tools to parse data from either
endpoint.
PHAB_ID=D279779
No Changes
- Propagate the admin server's shutdown to the handlers that are registered with the admin server.
PHAB_ID=D254656
No Changes
No Changes

via c.t.server.AdminHttpServer#addAdminRoutes.
PHAB_ID=D230247
- Update BuildProperties to not emit a warning when no build.properties file can be
located.
PHAB_ID=D229586
No Changes
- Move logic to parse the server build.properties file out the c.t.server.handler.ServerInfoHandler
and into a utility object, c.t.server.BuildProperties to allow for accessing by other server
logic such that the properties do not need to be re-parsed anytime access is desired. Failure to
load the properties can result in the server not starting in the case of a Fatal exception
being thrown.
PHAB_ID=D201207 - Update TwitterServer trait to override the inherited ShutdownTimer to be the Finagle
DefaultTimer instead of the c.t.util.JavaTimer defined by default in c.t.app.App. Also
update the overridden suppressGracefulShutdownErrors in TwitterServer to be a val since
it is constant (instead of a def).
PHAB_ID=D212896
- Add onExit lifecycle callback to c.t.server.Hook (which is now an abstract class) to allow
implemented hooks to execute functions in the App#onExit lifecycle phase. Note:
c.t.server.Hook#premain now has a default implementation and requires the override modifier.
PHAB_ID=D198379
No Changes
- Added an admin page at "/admin/balancers.json" with details about client load balancers,
including both configuration and current status.

code in twitter-server which used it.
PHAB_ID=D129515
No Changes
- Treat io.netty.channel.epoll.Native.epollWait0 as an idle thread on
"/admin/threads". This method is observed when using Netty 4's native
transport.
PHAB_ID=D115058
- Change to apply JUL log format in the c.t.server.logging.Logging trait
constructor instead of in premain to apply format as early in the logging
stack as possible. However, this means that users overriding the
def defaultFormatter will not be able to use any flags to configure their
formatting, note: the default LogFormatter does not use flags.
PHAB_ID=D106534
- From now on, release versions will be based on release date in the format of
YY.MM.x where x is a patch number.
PHAB_ID=D101244

c.t.finagle.toggle.StandardToggleMap registered Toggles.
RB_ID=847434
- Removed AdminHttpServer#mkRoutex method. This method was created during the
migration away from direct usage of netty http types and is now
redundant.
RB_ID=835083 - Builds are now only for Java 8 and Scala 2.11. See the
blog post
for details.
RB_ID=828898

performance or configuration.
RB_ID=754348
- We no longer export a "scheduler/productivity" stat because various implementation details made it difficult to report reliably.
- Converted to finagle-httpx. Projects that depend transitively on
finagle-http through twitter-server will need to switch to finagle-httpx.
RB_ID=741454RB_ID=740731
- Enable syntax highlighting in the docs
- Introduce AbstractTwitterServer, a Java-friendly version of TwitterServer. RB_ID=661878
- TwitterServer collects a statically allocated ring of runtime events, which be viewed at /admin/events, and downloaded as JSON with a HTTP client like curl (or by simply omitting the User-Agent header in the request).
- TwitterServer exports runtime configuration data about your service, which can be downloaded as json at /admin/registry.json.
- Bumped many dependency versions.
- Most noticeably, the admin server received a complete UI redesign. All http endpoints are now available via a navigation pane. We provide a simple API for service owners to include ad-hoc admin pages which will be part of the navigation pane. Note, it is still possible to join the admin server’s namespace via the global com.twitter.finagle.http.HttpMuxer.
- When using the twitter Metrics library, the admin server now scrapes your stats to extract a quick summary of how your server is performing. This includes secondly success rates for your server and least performant downstreams. We provide a /admin/metrics endpoint which can watch stats (at secondly granularity) and extract them via http queries.
- More recently, Finagle clients and servers began to retain information about their composition. This is useful in examining the modules and parameters that comprise a specific implementation. We now surface this information in the admin server via /admin/clients/<client_name> and /admin/servers/<server_name>
- TwitterServer now exposes a /admin/registry.json endpoint, which speaks json and exposes the values from util-registry as labels. Most labels are long-lived, and tend to represent something about a process that is true for the entire lifetime, like the version of a library, or what a flag was set to.
