Unreleased
----------
Bug Fixes
~~~~~~~~~
* finagle-http2: http2 servers no longer leak ping bodies. ``PHAB_ID=D130503``
Deprecations
~~~~~~~~~~~~
* finagle-core: `c.t.finagle.ssl.Ssl` and related classes have been
deprecated. They were replaced as the primary way of using SSL/TLS
within Finagle in release 6.44.0 (April 2017). Please migrate to using
`c.t.f.ssl.client.SslClientEngineFactory` or
`c.t.f.ssl.server.SslServerEngineFactory` instead. ``PHAB_ID=D129692``
New Features
~~~~~~~~~~~~
* finagle-thriftmux: Expose the underlying configured client `label` in the
`c.t.finagle.thriftmux.MethodBuilder`. ``PHAB_ID=D129109``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-base-http: `c.t.f.h.codec.HttpCodec` has been moved to the `finagle-http`
project. ``PHAB_ID=D116364``
* finagle base-http: `c.t.f.h.Request.multipart` has been removed.
Use `c.t.f.h.exp.MultipartDecoder` instead. ``PHAB_ID=D129158``
* finagle-http: Split the toggle 'c.t.f.h.UseH2C' into a client-side toggle and a
server-side toggle, named 'c.t.f.h.UseH2CClients', and 'c.t.f.h.UseH2CServers',
respectively. ``PHAB_ID=D130988``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-core: Finagle clients with retry budgets or backoffs should no
longer have infinite hash codes. ``PHAB_ID=D128594``
18.1.0
-------
New Features
~~~~~~~~~~~~
* finagle-core: `FailureDetector` has a new method, `onClose`, which provides
a Future that is satisfied when the `FailureDetector` marks a peer as Closed.
``PHAB_ID=D126840``
* finagle-core: Introduce trace logging of requests as they flow through a
Finagle client or server. These logs can be turned on at runtime by setting
the "com.twitter.finagle.request.Logger" logger to trace level.
``PHAB_ID=D124352``
* finagle-http2: HTTP/2 clients now expose the number of currently opened streams under
the `$client/streams` gauge. ``PHAB_ID=D127238``
* finagle-http2: HTTP/2 servers now expose the number of currently opened streams under
the `$server/streams` gauge. ``PHAB_ID=D127667``
* finagle-memcached: By default, the Memcached client now creates two connections
to each endpoint, instead of 4. ``PHAB_ID=D119619``
* finagle-redis: Add support for redis Geo Commands. ``PHAB_ID=D123167`` based on the PR
https://github.com/twitter/finagle/pull/628 written by Mura-Mi [https://github.com/Mura-Mi]
* finagle-thrift: Add `c.t.f.thrift.service.ThriftServiceBuilder` and
`c.t.f.thrift.service.ReqRepThriftServiceBuilder` for backwards compatibility
of creating higher-kinded method-per-endpoint clients. ``PHAB_ID=D127538``
* finagle-core: `c.t.f.http.MethodBuilder` and `c.t.f.thriftmux.MethodBuilder` now
expose `idempotent` and `nonIdempotent` methods, which can be used to configure
retries and the sending of backup requests. ``PHAB_ID=D122087``
Bug Fixes
~~~~~~~~~
* finagle-mysql: Fix a bug with transactions where an exception during a rollback
could leave the connection with a partially committed transaction. ``PHAB_ID=D122771``
* finagle-toggle: `c.t.f.toggle.Toggle`s are independent; that is, applying the same value to
two different toggles with the same fraction will produce independent true/false
values. ``PHAB_ID=D128172``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-core, finagle-netty4: When creating engines, SslClientEngineFactories now use
`SslClientEngineFactory.getHostString` instead of `SslClientEngineFactory.getHostname`.
This no longer performs an unnecessary reverse lookup when a hostname is not supplied
as part of the `SslClientConfiguration`. ``PHAB_ID=D124369``
* finagle-http2: Supplies a dependency on io.netty.netty-tcnative-boringssl-static,
which adds support for ALPN, which is necessary for encrypted http/2. To use a
different static ssl dependency, exclude the tcnative-boringssl dependency and
manually depend on the one you want to use. ``PHAB_ID=D119555``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-base-http, finagle-http: Removed Apache Commons Lang dependency,
`org.apache.commons.lang3.time.FastDateFormat` now is `java.time.format.DateTimeFormatter`.
``PHAB_ID=D121479``
* finagle-base-http: `c.t.f.http.Message.headerMap` is now an abstract method.
``PHAB_ID=D120931``
* finagle-core: `c.t.f.ssl.server.SslServerSessionVerifier` no longer uses the unauthenticated
host information from `SSLSession`. ``PHAB_ID=D124815``
* finagle-memcached: `ConcurrentLoadBalancerFactory` was removed and its behavior
was replaced by a Stack.Param inside finagle-core's `LoadBalancerFactory`.
``PHAB_ID=D119394``
* finagle-netty4: `Netty4ClientEngineFactory` and `Netty4ServerEngineFactory` were finalized.
``PHAB_ID=D128708``
* finagle-thrift, finagle-thriftmux: Remove `ReqRep` specific methods. Since the "ReqRep"
builders are now subclasses of their non-"ReqRep" counterparts their is no longer a
need to expose "ReqRep" specific methods. ``PHAB_ID=D123341``
Deprecations
~~~~~~~~~~~~
* finagle-exp: `c.t.f.exp.BackupRequestFilter` has been deprecated. Please use
`c.t.f.client.BackupRequestFilter` instead. ``PHAB_ID=D122344``
* finagle-http: `c.t.f.http.Request.multipart` has been deprecated.
Use `c.t.f.http.exp.MultipartDecoder` instead. ``PHAB_ID=D126013``
17.12.0
-------
New Features
~~~~~~~~~~~~
* finagle-core: Expose Tunables for MethodBuilder timeout configuration. Update
the http.MethodBuilder and thriftmux.MethodBuilder to accept Tunables for
configuring total and per-request timeouts. ``PHAB_ID=D118114``
* finagle-thrift, finagle-thriftmux: Add support for Scrooge
`ReqRepServicePerEndpoint` functionality. ``PHAB_ID=D107397``
* finagle-thriftmux: Add support for Scrooge `ServicePerEndpoint` and
`ReqRepServicePerEndpoint` functionality to `thriftmux.MethodBuilder`.
``PHAB_ID=D116081``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-base-http: Remove deprecated [Request|Response].[encode|decode][Bytes|String]
methods. Use c.t.f.h.codec.HttpCodec methods instead. ``PHAB_ID=D116350``
* finagle-memcached: `ConcurrentLoadBalancerFactory` was removed and its behavior
was replaced by a Stack.Param inside finagle-core's `LoadBalancerFactory`.
``PHAB_ID=D119394``
* finagle-serversets: Removed Guava dependency which broke some APIs. ``PHAB_ID=D119555``
- `c.t.f.common.zookeeper.ServerSets.TO_ENDPOINT` is now a `java.util.function.Function`.
- `c.t.f.common.net.pool.DynamicHostSet.HostChangeMonitor.onChange` now takes a `java.util.Set`.
- `c.t.f.common.zookeeper.ZooKeeperUtils.OPEN_ACL_UNSAFE` is is now a `java.util.List`.
- `c.t.f.common.zookeeper.ZooKeeperUtils.EVERYONE_READ_CREATOR_ALL` is is now a `java.util.List`.
- `c.t.f.common.zookeeper.ZooKeeperClient` constructor now takes a `java.util.Optional`.
* finagle-thrift: Move `ThriftRichClient` and `ThriftRichServer` to
`c.t.finagle.thrift` package. ``PHAB_ID=D115284``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-core: Remove `NackAdmissionControl` from the default client stack.
Add it to the finagle-{http,mux} client stacks; note that it is added to
finagle-http2 via finagle-http and finagle-thriftmux via finalge-mux. It is
no longer part of the finagle-{memcached,mysql,redis} client stacks.
``PHAB_ID=D116722``
* finagle-core: The "pipelining/pending" stat has been removed from protocols
using `c.t.f.dispatch.PipeliningClientDispatcher`. Refer to the "pending" stat
for the number of outstanding requests. ``PHAB_ID=D113424``
* finagle-thrift,thriftmux: Tracing of RPC method names has been removed. This
concern has moved into Scrooge. ``PHAB_ID=D115294``
Deprecations
~~~~~~~~~~~~
* finagle-core: `c.t.f.BackupRequestLost` has been deprecated. Please use a
`c.t.f.Failure` flagged `c.t.f.Failure.Ignorable` instead. ``PHAB_ID=D113466``
17.11.0

New Features
~~~~~~~~~~~~
* finagle-core: Add `ResponseClassifier`s, RetryOnTimeout and RetryOnChannelClosed,
for exceptions that are commonly retried when building from ClientBuilder but had
no MethodBuilder equivalents. ``PHAB_ID=D106706``
* finagle-netty4: `Netty4Transporter` and `Netty4Listener` are now accessible, which
allows external users to create their own protocols for use with Finagle on Netty 4.
``PHAB_ID=D105627``
Bug Fixes
~~~~~~~~~
* finagle-exp: Fix race condition in `LatencyHistogram` which could lead to the wrong
value returned for `quantile`. ``PHAB_ID=D106330``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-core: Numerous overloads of `c.t.f.Server.serve` have been marked final.
``PHAB_ID=D107280``
* finagle-thrift: Correctly send `mux.Request#contexts` in all cases. There were some
cases in which `mux.Request#contexts` were not always propagated. The contexts are
now always written across the transport. Note that there may be duplicated contexts
between "local" context values and "broadcast" context values. Local values will
precede broadcast values in sequence. ``PHAB_ID=D107921``
17.10.0

Release Version Format
~~~~~~~~~~~~~~~~~~~~~~
* 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``
New Features
~~~~~~~~~~~~
* finagle-core: DeadlineFilter may now be created from the class and used as a
regular Filter in addition to a stack module as before. ``PHAB_ID=D94517``
* finagle-mysql: Add ability to toggle the `CLIENT_FOUND_ROWS` flag. ``PHAB_ID=D91406``
* finagle-http: Separated the DtabFilter.Extractor from the ServerContextFilter into
a new module: ServerDtabContextFilter. While this is still enabled in the default
Http server stack, it can be disabled independently of the ServerContextFilter.
``PHAB_ID=D94306``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-netty4: `Netty4ClientEngineFactory` and `Netty4ServerEngineFactory` now
validate loaded certificates in all cases to ensure that the current date
range is within the validity range specified in the certificate. ``PHAB_ID=D88664``
* finagle-netty4: `TrustCredentials.Insecure` now works with native SSL/TLS engines.
``PHAB_ID=D103766``
* finagle-http2: Upgraded to the new netty http/2 API in netty version 4.1.16.Final,
which fixes several long-standing bugs but has some bugs around cleartext http/2.
One of the work-arounds modifies the visibility of a private field, so it's incompatible
with security managers. This is only true for http/2--all other protocols will be unaffected.
``PHAB_ID=D98069``
* finagle-http: Netty 3 `HeaderMap` was replaced with our own implementation.
``PHAB_ID=D99127``
Deprecations
~~~~~~~~~~~~
* finagle-base-http: With the intention to make `c.t.f.http.Cookie` immutable,
`set` methods on `c.t.f.http.Cookie` have been deprecated:
- `comment_=`
- `commentUrl_=`
- `domain_=`
- `maxAge_=`
- `path_=`
- `ports_=`
- `value_=`
- `version_=`
- `httpOnly_=`
- `isDiscard_=`
- `isSecure_=`
Use the `c.t.f.http.Cookie` constructor to set `domain`, `maxAge`, `path`, `value`, `httpOnly`,
and `secure`. `comment`, `commentUrl`, `ports`, `version`, and `discard` have been removed
per RFC-6265. ``PHAB_ID=D82164``.
Alternatively, use the `domain`, `maxAge`, `path`, `httpOnly`, and `secure` methods to create a
new `Cookie` with the existing fields set, and the respective field set to a given value.
``PHAB_ID=D83226``
* finagle-base-http: `c.t.f.http.Cookie.isSecure` and `c.t.f.http.Cookie.isDiscard`
have been deprecated. Use `c.t.f.http.Cookie.secure` for `c.t.f.http.Cookie.isSecure`.
`isDiscard` has been removed per RFC-6265. ``PHAB_ID=D82164``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-mysql: Moved `Cursors.cursor` method to `Client` trait, and removed `Cursors` trait.
This allows cursor queries to used with transactions. ``PHAB_ID=D91789``
* finagle-mux: Expose transport contexts in mux.Request and mux.Response. ``PHAB_ID=D92998``
* finagle-mux: The "leased" gauge has been removed from the mux client implementation since the
metric is reported as the sum of the value over all clients which is unlikely to be useful.
``PHAB_ID=D100357``
7.1.0
------
New Features
~~~~~~~~~~~~
* finagle-core: If a `c.t.u.tunable.Tunable` request or total timeout has been configured
on a client which uses a `c.t.f.client.DynamicTimeout` filter, the current value of tunable will
be used in the case of no dynamic timeout set for a request. ``PHAB_ID=D81886``
* finagle-core: `FailFastException` now captures the throwable that caused it. ``PHAB_ID=D86396``
* finagle-redis: finagle interface for redis DBSIZE command. ``PHAB_ID=D85305``
Bug Fixes
~~~~~~~~~
* finagle-core: Unregister `ServerRegistry` entry on `StackServer#close`. A
StackServer entry is registered in the `ServerRegistry` on serve of the
server but never unregistered. It is now unregistered on close of
the StackServer. ``PHAB_ID=D83200``
* finagle-mux: Fix two issues with mux leases. In one bug, a new lease wouldn't be sent to
the client if it was issued within 1 second of when the existing lease was set to expire.
In a second bug, the server would only nack if the issued lease was 0, but didn't consider
whether the lease had expired. ``PHAB_ID=D91645``
* finagle-netty4: `Netty4ClientEngineFactory` and `Netty4ServerEngineFactory` now
properly load all chain certificates when the `SslClientConfiguration` or
`SslServerConfiguration` uses `KeyCredentials.CertKeyAndChain` instead of just the
first one in the file. ``PHAB_ID=D82414``
* finagle-thrift/thriftmux: Thrift/ThriftMux servers and clients now can be configured
with `withMaxReusableBufferSize` to specify the max size of the reusable buffer for
Thrift responses. ``PHAB_ID=D83190``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-stats: Verbosity levels are now respected: debug-metrics aren't exported
by default. ``PHAB_ID=D85278``
* finagle-netty4: `ChannelTransport` no longer considers the `Channel.isWritable` result
when determining status. ``PHAB_ID=D82670``
Deprecations
~~~~~~~~~~~~
* finagle-base-http: Encoding/decoding methods on `c.t.f.http.Request` and `c.t.f.http.Response`
to/from Strings and arrays of bytes have been deprecated. Use the methods on
`c.t.f.http.codec.HttpCodec` instead:
- For `c.t.f.http.Request.encodeString`, use `c.t.f.Http.codec.HttpCodec.encodeRequestToString`
- For `c.t.f.http.Request.encodeBytes`, use `c.t.f.Http.codec.HttpCodec.encodeRequestToBytes`
- For `c.t.f.http.Request.decodeString`, use `c.t.f.Http.codec.HttpCodec.decodeStringToRequest`
- For c.t.f.http.Request.decodeBytes`, use `c.t.f.Http.codec.HttpCodec.decodeBytesToRequest`
- For `c.t.f.http.Response.encodeString`, use `c.t.f.Http.codec.HttpCodec.encodeResponseToString`
- For `c.t.f.http.Response.decodeString`, use `c.t.f.Http.codec.HttpCodec.decodeStringToResponse`
- For `c.t.f.http.Response.decodeBytes`, use `c.t.f.Http.codec.HttpCodec.decodeBytesToResponse`

project, finagle-netty3-http, in preparation for removing it from Finagle.
``PHAB_ID=D84101``
* finagle-memcached: Remove deprecated method `BaseClient.release()`. Use
`BaseClient.close()` instead. ``PHAB_ID=D83168``
Deprecations
~~~~~~~~~~~~
* finagle-memcached: Move `c.t.f.memcached.java.Client` to `c.t.f.memcached.JavaClient`,
`c.t.f.memcached.java.ClientBase` to `c.t.f.memcached.JavaClientBase`, and
`c.t.f.memcached.java.ResultWithCAS` to `c.t.f.memcached.ResultWithCAS`. ``PHAB_ID=D83719``
* finagle-core: Added a new type member `Context` to `Transport`, and a method that
returns a context, which has most of the methods currently directly on `Transport`.
Also deprecates most of those methods--please start using the context instead of the
`Transport` directly. Also added type parameters to `Transporter`, `Listener`, and
type members to `StackClient` and `StackServer`. ``PHAB_ID=D83972``
* finagle-core: `com.twitter.finagle.loadbalancer.DeterministicOrdering` was renamed
to `com.twitter.finagle.loadbalancer.ProcessCoordinate` and the internal `Coord` ADT
was changed as well. ``PHAB_ID=D84452``
* finagle-thrift: Move `Thrift.Server.param.MaxReusableBufferSize` to
`Thrift.param.MaxReusableBufferSize` for both server and client use. ``PHAB_ID=D83190``
7.0.0
------
New Features
~~~~~~~~~~~~
* finagle-core: A `StackClient` can be configured with a `c.t.u.tunable.Tunable`
request timeout using `.withRequestTimeout(tunable)`; this facilitates changing
the timeout at runtime, without server restart.
See https://twitter.github.io/finagle/guide/Configuration.html#tunables for details.
``PHAB_ID=D80751``.
* finagle-core: `SslClientSessionVerifier` and `SslServerSessionVerifier` have been added
as `Stack` params for executing custom SSL/TLS `Session` verification logic on the
establishment of an SSL/TLS `Session`. ``PHAB_ID=D63256``
* finagle-core: `tls` methods which take an `SslClientSessionVerifier` have
been added to `ClientBuilder` and `ClientTransportParams`
(withTransport.tls). `tls` methods which take an `SslServerSessionVerifier`
have been added to `ServerBuilder` and `ServerTransportParams`
(withTransport.tls). ``PHAB_ID=D68645``
* finagle-core: Timer tasks submitted to the `c.t.f.util.DefaultTimer` can have their
execution time monitored. Slow executing tasks may result in a log message at level WARN
and a counter of slow tasks is kept under `finagle/timer/slow`. This can be enabled using
the global flag `c.t.f.util.defaultTimerProbeSlowTasks` and the maximum allowed runtime
and minimum duration between log messages can be tuned using the global flags
`c.t.f.util.defaultTimerSlowTaskMaxRuntime`, and
`c.t.f.util.defaultTimerSlowTaskLogMinInterval`, respectively. ``PHAB_ID=D70279``
* finagle-core: The JVM metrics for GC, allocations, memory, and more have moved
here from TwitterServer. See the new JVM section in the user guide for details:
https://twitter.github.io/finagle/guide/Metrics.html
``PHAB_ID=D80883``
* finagle-http, finagle-thriftmux: `MethodBuilder` has been promoted out of experimental.
`MethodBuilder` is a collection of APIs for client configuration at a higher level than
the Finagle 6 APIs while improving upon the deprecated `ClientBuilder`.
See the user guide for details: https://twitter.github.io/finagle/guide/MethodBuilder.html
``PHAB_ID=D60032``
* finagle-http: add `withNoAutomaticContinue` api to disable automatically sending 100 CONTINUE
responses. ``PHAB_ID=D80017``
* finagle-http: The nack related logic in the `c.t.f.h.c.HttpClientDispatcher` has been
moved into a filter, `c.t.f.h.f.ClientNackFilter` which has been added to the client
stack and can now be removed based on its `Stack.Role`. ``PHAB_ID=D78902``
* finagle-init: Introduce a module to support service-loading initialization
code. ``PHAB_ID=D75950``
* finagle-memcached: Added support for partitioned backends in finagle client. Introducing
the new PartitioningService (``PHAB_ID=D75143``), KetamaPartitioningService (``PHAB_ID=D77499``)
and MemcachedPartitioningService (``PHAB_ID=D78927``), which provide this support at different
levels of abstraction. The c.t.f.Memcached util, that is used for creating new memcached
clients, now creates a new partitioning client that utilizes these new services for the
Memcached protocol. The new memcached client can be enabled by setting the toggle
"com.twitter.finagle.memcached.UsePartitioningMemcachedClient" to 1.0. ``PHAB_ID=D80352``
* finagle-mux: Default to new more efficient decoder. ``PHAB_ID=D80225``
* finagle-mysql: `IsolationLevel` support was added with
`Transactions.transactionWithIsolation` method, so the default level can be overridden
at the transaction level. ``PHAB_ID=D68944``
* finagle-mysql: Add support for unsigned integers. When enabled, unsigned integers that do
not fit into the existing signed representation are widened. For example an unsigned
Int32 is represented as a Java Long, etc. Because this changes the `c.t.f.mysql.Value`
variant returned by the row, it is disabled by default and must be enabled with the param
`c.t.f.Mysql.param.UnsignedColumns`. ``PHAB_ID=D78721``
* finagle-netty4: Adds support for passing a chain file to the default TLS implementation.
``PHAB_ID=D59531``
* finagle-netty4: Netty 4 transports now use pooled allocators by default. ``PHAB_ID=D75014``
* finagle-netty4: `KeyCredentials.CertKeyAndChain` is now available to use with
`Netty4ServerEngineFactory`. ``PHAB_ID=D80494``
* finagle-netty4: `c.t.f.netty4.trackReferenceLeaks` is now a CLI flag (default: disabled)
rather than a toggle. ``PHAB_ID=D80654``
* finagle-stats: Metrics now report verbosity levels via `MetricsView.verbosity`.
``PHAB_ID=D78150``
* finagle-stats: `JsonExporter` now respects verbosity levels (current default behavior is
to keep exporting "debug" metrics). Adjust `com.twitter.finagle.stats.verbose` tunable
whitelist to change it. ``PHAB_ID=D79571``
* finagle-tunable: `StandardTunableMap` is now public. Users can access file-based, in-memory,
and service-loaded tunable values using the map.
See https://twitter.github.io/finagle/guide/Configuration.html#tunables for details.

* finagle-mysql: Fix decoding error for medium length integers. ``PHAB_ID=D78505``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle: Finagle is now decoupled from Netty 3. Depend on `finagle-netty3`
explicitly if needed. ``PHAB_ID=D65268``
* finagle-base-http: The HTTP message model has been refactored to remove backing
Netty 3 types. Additionally, the `Request` and `Response` classes now have private
constructors to enforce a more appropriate inheritance model: `Request.Proxy` and
`Response.Proxy` are now the point of entry for extending the HTTP model types. Along
with the model changes the InputStream generated `.getInputStream()` method of HTTP
messages no longer consumes the messages body. ``PHAB_ID=D74519``
* finagle-core: The Framer type has been transformed into a specialized version of a
more generic abstraction, Decoder[T]. ``PHAB_ID=D59495``
* finagle-core: Replace the `c.t.f.context.RemoteInfo.Available` constructor
which takes `ClientId` in favor of a version taking `String`. `ClientId` is
Twitter's Thrift specific concept and this should be more generic.
``PHAB_ID=D60136``
* finagle-core: Remove the ability to set a global address sort. This is no longer
necessary as setting this per client is sufficient. ``PHAB_ID=D60698``
* finagle-core: Remove global flag `com.twitter.finagle.tracing.debugTrace`.
This functionality is better suited as a concrete `Tracer` implementation instead
of mixed into the generic code. ``PHAB_ID=D63252``
* finagle-core: ``PHAB_ID=D63526``
- `ClientBuilder.codec` and `ServerBuilder.codec` have been removed. Use `.stack` instead.
- `ClientBuilder.channelFactory` and `ServerBuilder.channelFactory` have been removed.
Use `.stack` instead.
* finagle-core: LoadBalancerFactory now takes `Stack.Params` which allows a client to
more easily pass in the stack context. ``PHAB_ID=D73129``
* finagle-memcached: Add `c.t.util.Closable` trait to `c.t.f.memcached.BaseClient`.
``PHAB_ID=D63970``
* finagle-mysql: A number of implementation details were made private such as specific
`Row` implementations and `ResultSet` builder functions that consume raw packets.
``PHAB_ID=D78721``
* finagle-netty4-http: HTTP/1.1 implementation based on Netty 4 is no longer experimental
and is moved out of the `exp` package. ``PHAB_ID=D80181``
* finagle-serversets: Remove `ZkMetaData.AddressOrdering``, it is no longer used.
``PHAB_ID=D60698``
* finagle-stats: `c.t.f.stats.MetricsStatsReceiver` no longer has constructor variants
which take a `c.t.u.events.Sink` as util-events is now deprecated. ``PHAB_ID=D64437``
* finagle-thrift: The Netty3 thrift implementation has been removed.
``PHAB_ID=D63670``
* finagle-zipkin-core: `c.t.f.zipkin.core.SamplingTracer` no longer has constructor
which takes a `c.t.u.events.Sink` as util-events is now deprecated. ``PHAB_ID=D64437``
* finagle-zipkin: Zipkin Tracer now exports only three counters: `requests`, `failures`,
`success`. ``PHAB_ID=D71965``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-core: The `AsyncSemaphore` which sequences dispatches in `GenSerialClientDispatcher`
is now failed with a retryable `Failure` so that the retry logic knows that requests that
which failed to acquire the semaphore are safe to retry. ``PHAB_ID=D78904``
* finagle-http: `serverErrorsAsFailuresV2` toggle is turned into a flag `serverErrorsAsFailures`.
``PHAB_ID=D73265``
* finagle-http: Dispatcher stats are now exported under the client scope like
all other client stats.``PHAB_ID=D72265``
* finagle-http: It's now possible to send a response from the HTTP server that has a
Content-Length header so long as the 'Transfer-Encoding: chunked' isn't set on the response.
``PHAB_ID=D80087``
* finagle-http: Non-streaming servers strip 'expect' headers when a 100 CONTINUE
response is sent. ``PHAB_ID=D80017``
* finagle-serversets: `Stabilizer` is no longer exporting `pending_tasks` and `deviation_ms`
stats. See `notify_ms` instead. ``PHAB_ID=D65571``
* finagle-stats, finagle-zipkin-core: No longer publishing `c.t.u.events` as util-events
is now deprecated. ``PHAB_ID=D64437``
* finagle-stats: No longer backed by commons metrics, now its own thing. ``PHAB_ID=D73497``
* finagle-netty4: Unset Netty's default timeout (10 seconds) for SSL handshake on clients.
Use `.withSession.acquisitionTimeout` instead. ``PHAB_ID=D78500``
6.45.0

* finagle: Changed dependencies of Netty from 4.1.9 to 4.1.10 and tcnative
from 2.0.0 to 2.0.1. ``RB_ID=916056``
* finagle-core: `c.t.f.n.ssl.SslConnectHandler` is no longer exported publicly.
It has also been renamed to `c.t.f.n.ssl.client.SslClientConnectHandler`.
``RB_ID=916932``
* finagle-core: c.t.f.factory.ServiceFactoryCache is now exported publicly.
``RB_ID=915064``

~~~~~~~~~
* finagle-mux: Disable Netty4RefCountingControl decoder when message fragmentation
is enabled. ``PHAB_ID=D58153``
* finagle: Fixed Java API for `withStack` for Client and Server implementations.
Java users now get the correct types for calls such as `c.t.f.Http.client().withStack`
and `c.t.f.Http.server().withStack`. ``RB_ID=915440``
* finagle-thrift, finagle-thriftmux: Clients created using `newServiceIface` now use the
configured `c.t.f.service.ResponseClassifier` (or `c.t.f.service.ResponseClassifier.Default` if
not configured) for per-method stats and usage in `c.t.f.liveness.FailureAccrualFactory` and
`c.t.f.stats.StatsFilter`. ``RB_ID=917010``
Runtime Behavior Changes

* finagle: Add a floor of 8 to the default values of the flags `c.t.f.netty3.numWorkers`
and `c.t.f.netty4.numWorkers`. ``RB_ID=916465``
* finagle-core: `c.t.f.util.DefaultTimer` is decoupled from Netty 3 and is loaded via the
`LoadService` machinery. If no timers are available on the class path, the `JavaTimer`
instead is used instead. This ony affects direct usages of `DefaultTimer` as all Finagle
protocols are using Netty 4 `HashedWheelTimer` at this point. ``RB_ID=915924``
* finagle-core: The load balancer implementations no longer close the endpoint
resources when they are closed. Instead, they treat them as externally
managed resources and expect the layers above to manage them. No change
is required if using the Balancers in the context of a Finagle client.
If that's not the case, however, managing the life cycle of the passed
in endpoints is necessary. ``RB_ID=916415``
* finagle-core: Aperture load balancers now expire idle sessions which fall
out of the aperture window. ``RB_ID=916508``
* finagle-http: Uses Netty 4 as the default transport implementation.
Use `.configured(Http.Netty3Impl)` to switch implementation over to Netty 3.
``PHAB_ID=D58698`` ``RB_ID=917936``
* finagle-memcached: If the client decoder detects a protocol failure, the ClientTransport
will close the connection. ``RB_ID=917685``
* finagle-netty4: `poolReceiveBuffers` toggle is removed (suppressed by `UsePooling`).
``RB_ID=917912``
* finagle-http: To conform to RFC 2616, a message body is NO LONGER sent when 1xx, 204
and 304 responses are returned. To conform with RFC 7230, a Content-Length header field
is NOT sent for 1xx and 204 responses. Both rules are enforced even if users intentionally
add body data or the header field for these responses. If violation of these rules is
detected then an error message is logged. ``RB_ID=917827``
Breaking API Changes

* finagle-core: Remove deprecated `c.t.f.builder.Cluster`. Use `com.twitter.finagle.Name` to
represent clusters instead. ``RB_ID=916162``
* finagle-core: LoadBalancerFactory now takes an EndpointFactory which is an
extension of ServiceFactory that carries an address and has the ability to
be rebuilt. ``RB_ID=916956``
* finagle-base-http: Remove deprecated `c.t.f.http.Message.ContentTypeWwwFrom`.

6.44.0
------
New Features
~~~~~~~~~~~~
* finagle-thriftmux: Allow ThriftMux.Servers to be filtered, also add `withStack`
method to server side as well. ``RB_ID=915095``
* finagle-core: FailureAccrual is now production ready. It has been promoted out of
experimental and moved from com.twitter.finagle.service.exp to
com.twitter.finagle.liveness. ``RB_ID=914662``
* finagle-core: SSL/TLS APIs have been changed to include methods which work
based on an SSL configuration, and an SSL configuration and an SSL engine factory.
``RB_ID=911209``
* finagle-core: LoadBalancerFactory now exposes a mechanism to order the collection
of endpoints passed to the balancer implementations. This allows a consistent ordering
of endpoints across process boundaries. ``RB_ID=910372``
* finagle-core: Introduce `c.t.f.client.EndpointerStackClient`, a mechanism for
making clients that don't need a transporter and dispatcher. This simplifies
making non-netty clients. ``RB_ID=912889``
* finagle-http2: Add support for liveness detection via pings. It can be configured
the same way as it is in mux. ``RB_ID=913341``
* finagle-toggle: Standard toggles now track the last value produced from `apply`.
These values are visible via TwitterServer's /admin/toggles endpoint. ``RB_ID=913925``
Breaking API Changes
~~~~~~~~~~~~~~~~~~~~
* finagle-mysql: Support for Netty 3 has been removed, making Netty 4 the only transport
implementation. ``RB_ID=914661``
* finagle-core: com.twitter.finagle.service.exp.FailureAccrualPolicy has been promoted to
com.twitter.finagle.liveness.FailureAccrualPolicy
* finagle-commons-stats: Remove finagle-commons-stats, which was a compatibility layer
for a deprecated stats library. Please move to finagle-stats instead. ``RB_ID=910964``
* finagle-core: SSL/TLS stack params for Finagle running Netty 4 have changed.
- The `TlsConfig` param in `Transport` has been removed.
- For client engines, the same two parameters as Finagle running Netty 3 are now used:
- `ClientSsl` in `Transport`, which is used for configuring a client `Engine`'s hostname,
key credentials, trust credentials, cipher suites, protocols, and application protocols.
- `SslClientEngineFactory` in `SslClientEngineFactory`, which determines how the `Engine`
is created based off of an `Address` and an `SslClientConfiguration`.
- For server engines, the same two parameters as Finagle running Netty 3 are now used:
- `ServerSsl` in `Transport`, which is used for configuring a server `Engine`'s key
credentials, trust credentials, cipher suites, protocols, application protocols, and
where the server supports or requires client authentication.
- `SslServerEngineFactory` in `SslServerEngineFactory`, which determines how the `Engine`
is created based off of an `SslServerConfiguration`.
- Note: Not all client and server configurations work with all engine factories. Each engine
factory should document what is not supported by that specific engine factory.
- Note: By default, Finagle on Netty 4 will use the `Netty4ClientEngineFactory` and
`Netty4ServerEngineFactory` respectively.
``RB_ID=910500``
* finagle-core: Change the API to LoadBalancerFactory to a more concrete
`Activity[IndexedSeq[ServiceFactory[Req, Rep]]]` since the majority of the
load balancer implementations don't need the properties of a Set but instead
need ordering guarantees and efficient random access. ``RB_ID=910372``
* finagle-core: Balancers.aperture now has a new parameter `useDeterministicOrdering`,
which is set to false by default. This feature is still experimental and under
construction. This will break the Java API and require the additional param to
be passed in explicitly. ``RB_ID=911541``
* finagle-core: The logic for tracking sessions that was in StdStackServer has been lifted into
a new template, ListeningStackServer where implementations define the creation of a
ListeningServer from a ServiceFactory, SocketAddress, and a function that tracks accepted
sessions. ``RB_ID=914124``
* finagle-core: Change the AddressOrdering param to no longer take a StatsReceiver,
since orderings were simplified and are no longer composite. ``RB_ID=914113``
* finagle-core: Remove deprecated methods on `c.t.f.Client`:
- newClient(dest: Group[SocketAddress])
- newService(dest: Group[SocketAddress])
``RB_ID=914787``
* finagle-core: `c.t.f.ListeningServer` no longer extends `c.t.f.Group`. Use
`c.t.f.ListeningServer.boundAddress` to extract the address from the server.
``RB_ID=914693``
* finagle-core: Remove deprecated `c.t.f.group.StabilizingGroup`. Use
`c.t.f.addr.StabilizingAddr` instead. ``RB_ID=914823``
* finagle-core: Constructors for `c.t.f.ChannelException` and its subclasses now have
overloads that take `Option`\s instead of allowing `null`. While the existing
constructors remain, and forward to the new ones, this can still cause compilation
failures when the arguments are ambiguous. ``RB_ID=914800``
* finagle-core: Remove MimimumSetCluster since it has been deperecated for quite
some time. Instead, use finagle logical destinations via `Name`s. ``RB_ID=914849``
* finagle-core: Remove deprecated `c.t.f.Resolver.resolve`. Use `c.t.f.Resolver.bind`
instead. Remove deprecated `c.t.f.BaseResolver.resolve`. Use `c.t.f.Resolver.eval`
instead. ``RB_ID=914986``
* finagle-http: `c.t.f.http.Http` codec has disappeared as part of Netty 4 migration. Use
`c.t.f.Http.client` or `c.t.f.Http.server` stacks instead. ``RB_ID=912427``
* finagle-kestrel: Remove `c.t.f.kestrel.param.KestrelImpl.` Kestrel clients and servers
now use Netty 4 and cannot be configured for Netty 3. ``RB_ID=911031``
* finagle-memcached: Remove `c.t.f.memcached.param.MemcachedImpl.` Memcached clients and servers
now use Netty 4 and cannot be configured for Netty 3. ``RB_ID=911031``
* finagle-kestrel: Remove commands that are not supported by the client:
- `com.twitter.finagle.kestrel.protocol.DumpConfig`
- `com.twitter.finagle.kestrel.protocol.DumpStats`
- `com.twitter.finagle.kestrel.protocol.FlushAll`
- `com.twitter.finagle.kestrel.protocol.Reload`
- `com.twitter.finagle.kestrel.protocol.ShutDown`
- `com.twitter.finagle.kestrel.protocol.Stats`
- `com.twitter.finagle.kestrel.protocol.Version`
``RB_ID=911206``
* finagle-memcached: Remove deprecated `c.t.f.memcached.KetamaClientBuilder`. Use
`c.t.f.Memcached.client` to create a Memcached client. ``RB_ID=907352``
* finagle-memcached: Remove deprecated `c.t.f.memcached.replication.ReplicationClient`. Use
`c.t.f.memcached.replication.BaseReplicationClient` with clients created using
`c.t.f.Memcached.client`. ``RB_ID=907352``
* finagle-memcached: Remove deprecated methods on `c.t.f.memcached.Client`:
- `apply(name: Name)`
- `apply(host: String)`
Use `c.t.f.Memcached.client` to create a Memcached client. ``RB_ID=908442``
* finagle-memcached: Remove deprecated `c.t.f.memcached.protocol.text.Memcached` object.
Use `c.t.f.Memcached.client` to create Memcached clients. ``RB_ID=908442``
* finagle-memcached: Remove deprecated `c.t.f.memcached.Server` class. Use
`c.t.f.memcached.integration.TestMemcachedServer` for a quick test server.
``RB_ID=914827``
* Remove deprecated `c.t.f.memcached.PartitionedClient` object. Use
`c.t.f.memcached.CacheNodeGroup.apply` instead of
`c.t.f.memcached.PartitionedClient.parseHostWeights`. ``RB_ID=914827``
* Remove deprecated `c.t.f.memcached.util.ParserUtils.DIGITS`. Use "^\\d+$" instead.
Remove deprecated `c.t.f.memcached.util.ParserUtils.DigitsPattern`. Use Pattern.compile(^\\d+$)
instead. ``RB_ID=914827``
* finagle-memcached: Remove old `c.t.f.memcached.replicated.BaseReplicationClient` and
`c.t.f.memcached.migration.MigrationClient`, and most `c.t.f.memcached.CachePoolCluster`
methods. ``RB_ID=910986``
* finagle-memcached: Remove old `c.t.f.memcached.migration.DarkRead`, and
`c.t.f.memcached.migration.DarkWrite`. ``RB_ID=911367``
* finagle-memcached: Remove `c.t.f.memcached.CachePoolConfig`. ``RB_ID=914623``
* finagle-mux: Netty 3 implementation of Mux is removed. Default is
Netty 4. ``RB_ID=914239``
* finagle-netty4: `DirectToHeapInboundHandler` was renamed to `AnyToHeapInboundHandler`
and now copies any inbound buffer (not just directs) on heap. ``RB_ID=913984``
* finagle-thrift, finagle-thriftmux: Remove rich client/server support for prior
versions of Scrooge generated code. ``RB_ID=911515``
* finagle-core: `c.t.f.client.Transporter` no longer has a close method, which
was introduced in 6.43.0. It was sort of a hack, and we saw the opportunity
to do it properly. ``RB_ID=912889``
* finagle-core, finagle-mux: Move FailureDetector from `c.t.f.mux` to `c.t.f.liveness`.
This also means that the `sessionFailureDetector` flag is now
`c.t.f.liveness.sessionFailureDetector`. ``RB_ID=912337``
Bug Fixes
~~~~~~~~~
* finagle-exp: `DarkTrafficFilter` now respects the log level when `HasLogLevel`,
and otherwise defaults the level to `warning` instead of `error`. ``RB_ID=914805``
* finagle-netty4: Fixed connection stall on unsuccessful proxy handshakes in Finagle clients
configured with HTTP proxy (`Transporter.HttpProxyTo`). ``RB_ID=913358``
Runtime Behavior Changes
~~~~~~~~~~~~~~~~~~~~~~~~
* finagle-netty4: Finagle is no longer logging the failed proxy handshake response.
``RB_ID=913358``
* finagle-netty4: SOCKS5 proxies are now bypassed if the connect destination is
localhost. This matches Finagle's prior behavior from when Netty 3 was the default
transport implementation. ``RB_ID=914494``
Dependencies
