Release Notes - Mesos - Version 1.7.3 (WIP)
-------------------------------------------
* This is a bug fix release.
** Bug
* [MESOS-8467] - Destroyed executors might be used after `Slave::publishResource()`.
* [MESOS-9507] - Agent could not recover due to empty docker volume checkpointed files.
* [MESOS-9529] - `/proc` should be remounted even if a nested container set `share_pid_namespace` to true.
* [MESOS-9549] - nvidia/cuda 10 does not work on GPU isolator.
* [MESOS-9564] - Logrotate container logger lets tasks execute arbitrary commands in the Mesos agent's namespace.
* [MESOS-9568] - SLRP does not clean up mount directories for destroyed MOUNT disks.
* [MESOS-9607] - Removing a resource provider with consumers breaks resource publishing.
* [MESOS-9610] - Fetcher vulnerability - escaping from sandbox.
* [MESOS-9616] - `Filters.refuse_seconds` declines resources not in offers.
* [MESOS-9619] - Mesos Master Crashes with Launch Group when using Port Resources
* [MESOS-9661] - Agent crashes when SLRP recovers dropped operations.
* [MESOS-9692] - Quota may be under allocated for disk resources.
* [MESOS-9695] - Remove the duplicate pid check in Docker containerizer
* [MESOS-9707] - Calling link::lo() may cause runtime error
* [MESOS-9750] - Agent V1 GET_STATE response may report a complete executor's tasks as non-terminal after a graceful agent shutdown.
* [MESOS-9766] - /__processes__ endpoint can hang.
* [MESOS-9786] - Race between two REMOVE_QUOTA calls crashes the master.
* [MESOS-9787] - Log slow SSL (TLS) peer reverse DNS lookup.
** Improvements
* [MESOS-8880] - Add minimum capabilities in the master.

* [MESOS-9704] - Support docker manifest v2s2 config GC.
* [MESOS-9759] - Log required quota headroom and available quota headroom in the allocator.
Release Notes - Mesos - Version 1.7.2
-------------------------------------
* This is a bug fix release.
** Bug
* [MESOS-8887] - Unreachable tasks are not GC'ed when unreachable agent is GC'ed.
* [MESOS-9210] - Mesos v1 scheduler library does not properly handle SUBSCRIBE retries.
* [MESOS-9517] - SLRP should treat gRPC timeouts as non-terminal errors, instead of reporting OPERATION_FAILED.
* [MESOS-9531] - chown error handling is incorrect in createSandboxDirectory.
* [MESOS-9532] - ResourceOffersTest.ResourceOfferWithMultipleSlaves is flaky.
* [MESOS-9533] - CniIsolatorTest.ROOT_CleanupAfterReboot is flaky.
* [MESOS-9537] - SLRP sends inconsistent status updates for dropped operations.
* [MESOS-9544] - SLRP does not clean up destroyed persistent volumes.
* [MESOS-9554] - Allocator might skip allocations because a single framework is incapable of receiving certain resources.
* [MESOS-9555] - Allocator CHECK failure: reservationScalarQuantities.contains(role).
** Improvement
* [MESOS-9340] - Log all socket errors in libprocess.
Release Notes - Mesos - Version 1.7.1
-------------------------------------
* This is a bug fix release. Also includes performance and API
improvements:
* **Allocator**: Improved allocation cycle time substantially
(see MESOS-9239 and MESOS-9249). These reduce the allocation
cycle time in some benchmarks by 80%.
* **Scheduler API**: Improved the experimental `CREATE_DISK` and
`DESTROY_DISK` operations for CSI volume recovery (see MESOS-9275
and MESOS-9321). Storage local resource providers now return disk
resources with the `source.vendor` field set, so frameworks needs to
upgrade the `Resource` protobuf definitions.
* **Scheduler API**: Offer operation feedbacks now present their agent
IDs and resource provider IDs (see MESOS-9293).
** Bug
* [MESOS-7042] - Send SIGKILL after SIGTERM to IOSwitchboard after container termination.
* [MESOS-7474] - Mesos fetcher cache doesn't retry when missed.
* [MESOS-8545] - AgentAPIStreamingTest.AttachInputToNestedContainerSession is flaky.
* [MESOS-8907] - Docker image fetcher fails with HTTP/2.
* [MESOS-8978] - Command executor calling setsid breaks the tty support.
* [MESOS-9131] - Health checks launching nested containers while a container is being destroyed lead to unkillable tasks.
* [MESOS-9152] - Close all file descriptors except whitelist_fds in posix/subprocess.
* [MESOS-9154] - MasterTest.TaskStateMetrics is flaky
* [MESOS-9164] - Subprocess should unset CLOEXEC on whitelisted file descriptors.
* [MESOS-9228] - SLRP does not clean up plugin containers after it is removed.
* [MESOS-9231] - `docker inspect` may return an unexpected result to Docker executor due to a race condition.
* [MESOS-9266] - Whenever our packaging tasks trigger errors we run into permission problems.
* [MESOS-9267] - Mesos agent crashes when CNI network is not configured but used.
* [MESOS-9274] - v1 JAVA scheduler library can drop TEARDOWN upon destruction.
* [MESOS-9279] - Docker Containerizer 'usage' call might be expensive if mount table is big.
* [MESOS-9281] - SLRP gets a stale checkpoint after system crash.
* [MESOS-9283] - Docker containerizer actor can get backlogged with large number of containers.
* [MESOS-9293] - If a framework looses operation information it cannot reconcile to acknowledge updates.
* [MESOS-9295] - Nested container launch could fail if the agent upgrade with new cgroup subsystems.
* [MESOS-9308] - URI disk profile adaptor could deadlock.
* [MESOS-9317] - Some master endpoints do not handle failed authorization properly.
* [MESOS-9324] - Resource fragmentation: frameworks may be starved of port resources in the presence of large number frameworks with quota.
* [MESOS-9332] - Nested container should run as the same user of its parent container by default.
* [MESOS-9334] - Container stuck at ISOLATING state due to libevent poll never returns.
* [MESOS-9362] - Test `CgroupsIsolatorTest.ROOT_CGROUPS_CreateRecursively` is flaky.
* [MESOS-9411] - Validation of JWT tokens using HS256 hashing algorithm is not thread safe.
* [MESOS-9418] - Add support for the `Discard` blkio operation type.
* [MESOS-9419] - Executor to framework message crashes master if framework has not re-registered.
* [MESOS-9474] - Master does not respect authorization result for `CREATE_DISK` and `DESTROY_DISK`.
* [MESOS-9479] - SLRP does not set RP ID in produced OperationStatus.
* [MESOS-9480] - Master may skip processing authorization results for `LAUNCH_GROUP`.
* [MESOS-9492] - Persist CNI working directory across reboot.
* [MESOS-9501] - Mesos executor fails to terminate and gets stuck after agent host reboot.
* [MESOS-9502] - IOswitchboard cleanup could get stuck due to FD leak from a race.
* [MESOS-9505] - `make check` failed with linking errors when c-ares is installed.
* [MESOS-9508] - Official 1.7.0 tarball can't be built on Ubuntu 16.04 LTS.
* [MESOS-9518] - CNI_NETNS should not be set for orphan containers that do not have network namespace.

Release Notes - Mesos - Version 1.7.0
-------------------------------------
This release contains the following highlights:
* Performance Improvements:
* **Master `/state` endpoint:** Adopted RapidJSON and reduced
copying for a ~130% throughput improvement due to a ~55%
decrease in latency (MESOS-9092). Also, added parallel
processing of `/state` requests to reduce master backlogging
/ interference under high request load (MESOS-9122).
* **Allocator:** Improved allocator cycle time significantly
(MESOS-9087). This, together with the reduced master
backlogging from `/state` improvements, reduces the
end-to-end offer cycling time between Mesos and schedulers.
* **Agent `/containers` endpoint:** Fixed a performance issue
that caused high latency / cpu consumption when there are
many containers on the agent (MESOS-8418).
* **Agent container launching performance improvements**:
The expensive `cgroups::verify()` calls were removed which
provides a significant improvement to container launch /
destroy throughput (MESOS-9081).
* Containerization:
* [MESOS-8794] - **Experimental** Supported docker image tarball
fetching from HDFS through the `--docker_registry` agent flag.
* [MESOS-7691] - Added a new option `cgroups/all` to the agent
flag `--isolation`. This allows cgroups isolator to
automatically load all the local enabled cgroups subsystems.
If this option is specified in the agent flag `--isolation`
along with other cgroups related options
(e.g., `cgroups/cpu`), those options will be just ignored.
* [MESOS-7947] - Added a new `--gc_non_executor_container_sandboxes`
option which tells the agent to garbage collect sandboxes created
via the LAUNCH_NESTED_CONTAINER API. The same flag will apply to
standalone container sandboxes in future.
* [MESOS-8327] - Added container-specific cgroups mounts under
`/sys/fs/cgroup` to containers with image launched by Mesos
containerizer.
* [MESOS-5647] - Expose network statistics for containers on
CNI network in the `network/cni` isolator.
* [MESOS-8792] - Added a new `linux/devices` isolator that
automatically populates containers with devices that have
been whitelisted with the `--allowed_devices` agent flag.
* [MESOS-8340] Added a new `--enforce_container_ports`
option to toggle ports resource enforcement by the
`network/ports` isolator.
* [MESOS-6451] - Add timer and percentile metrics for docker
pull latency distribution.
* Windows:
* [MESOS-8668] - Added support to libprocess for the Windows
Thread Pool API, replacing libevent with the native Windows
event and thread pool library. This can be enabled with
`-DENABLE_LIBWINIO=ON` during CMake configuration. By
utilizing I/O Completion Ports, this enables non-blocking
asynchronous I/O on Windows for sockets, pipes, and files.
* Multi-Framework Workloads:
* [MESOS-8842] - **Experimental** Added per-framework metrics
to the master. These new metrics provide detailed information
about the behavior of each framework and can help with
scalability testing, debugging, and fine grained monitoring.
Please refer to docs/monitoring.md for more details.
* [MESOS-8238] Documentation was added in the framework
development guide to provide recommendations on how schedulers
can behave co-operatively in a multi-framework setting, as
well as how to operationally configure Mesos in such a setting.
* [MESOS-8936] A new weighted random sorter was added as an
alternative to the existing DRF sorter, this allows users
that don't need DRF behavior to opt-out.
Additional API Changes:
* [MESOS-9066] - Introduced `CREATE_DISK` and `DESTROY_DISK` offer
operations to replace `CREATE_VOLUME`, `CREATE_BLOCK`,
`DESTROY_VOLUME` and `DESTROY_BLOCK`.
* Container logger module interface has been changed. The `prepare()` method
now takes `ContainerID` and `ContainerConfig` instead.
* `Isolator::recover` interface has been changed to take an `std::vector`
instead of `std::list`.
* JSON endpoints now use rapidjson to provide a performance improvement,
this means that if a client has a JSON de-serializer that does not
conform to the ECMA-404 spec for JSON, they may break. As an example,
Mesos would previously serialize '/' as '\/', but the spec does not
require the escaping and rapidjson does not escape '/'.
Changes to Dependencies:
* [MESOS-8395] - Made gRPC a requirement for Mesos builds. The `--enable-grpc`
Autotools option and the `-DENABLE_GRPC=ON` CMake option is now removed.
* [MESOS-8064] - Mesos now requires libarchive to programmatically decode
.zip, .tar, .gzip, and other common file compression schemes. Version 3.3.2
is bundled in Mesos.
* [MESOS-9092] - Adopt rapidjson for improved json serialization performance.
Version 1.1.0 is bundled in Mesos.

In the future, this feature will be extended to operations on agent default
resources.
* [MESOS-8534] - **Experimental** A nested container is now allowed
to join a separate CNI network than its parent container.
* [MESOS-8572] - Improvements to the Docker containerizer and executor
to more gracefully handle situations in which the Docker CLI is
unresponsive.

(CSI) version 0.2 in Mesos.
* [MESOS-8659] - The Windows build now links the C runtime library
dynamically instead of statically. This requires the Visual Studio
redistributable to be available at runtime.
* [MESOS-8682] - The use of the C runtime library's POSIX wrappers on
Windows has been deprecated in favor of the native Windows APIs.
* [MESOS-8725] - Added a new `max_completion_time` field to `TaskInfo`.
Tasks which do not complete at the end of the specified duration will
fail with a new reason `REASON_MAX_COMPLETION_TIME_REACHED`.
* [MESOS-8801] - **Experimental** On Linux, Mesos can now be
configured to use the jemalloc allocator by default via the
`--enable-jemalloc-allocator` configuration option.
* Agents now support the `--fetcher_stall_timeout` flag which allows container
image and artifact fetchers to abort after the timeout when downloads stall.
Deprecations/Removals:
* Support for CSI v0.1 is deprecated in favor of CSI v0.2.
Additional API Changes:
* [MESOS-8306] - Authorization of resource reservation has been updated
to allow the restriction of which agents can statically reserve
resources for which roles.

Release Notes - Mesos - Version 1.5.0
-------------------------------------------
This release contains the following new features:
* [MESOS-1739] - **Experimental** Agents now support the
`--reconfiguration_policy` flag which allows them to recover
the agent ID and running tasks after configuration changes.
See docs/agent-recovery.md for more details.
* [MESOS-4945] - **Experimental** Agents now can automatically
garbage collect unused Docker image layers used by Mesos
Containerizer.
* [MESOS-7289, MESOS-7235] - **Experimental** Support for the
Container Storage Interface (CSI) to simplify storage management
in Mesos, and allow 3rdparty vendors to plugin into Mesos very
easily.
* [MESOS-7302] - Support launching standalone containers on the
agent using MesosContainerizer without a master or framework
running.
* [MESOS-7749] - **Experimental** Support for gRPC client in Mesos.
The gRPC is bundled in Mesos and a gRPC client API is built is
built into libprocess.
* [MESOS-7973] - **Experimental** Non-leading replica is now allowed
to catch-up missing log positions in the replicated log. This opens
the door for implementing hot standby (by offloading some reading
from a leader to standbys) and fast failover time (by keeping
in-memory storage represented by the log “hot”).
* Several improvements and fixes to the enforcement of quota
guarantees have been made:
* [MESOS-4527]: Previously a role could "game" the quota system
by amassing reservations that it leaves unused. This is now
prevented by accounting for reservations when allocating
resources.
* [MESOS-7099]: Resources are now allocated in a fine-grained
manner to prevent roles from exceeding their quota.
* [MESOS-8293]: There was a bug where a role may not receive its
reservation when it does not have quota, this has been fixed.
* [MESOS-8339]: When a role has more reservations than quota,
there was a bug previously where an insufficient amount of
quota headroom was held. This has been fixed.
* [MESOS-8352]: When allocating to a role with quota, we
previously included all other resources on the agent that the
role does not have quota for. This made it possible to violate
the quota guarantees of a different role. This has been fixed
by taking into account the headroom that is needed when
allocating the resources.
Deprecations/Removals:
* [MESOS-7305] - Some nested container agent APIs `****_NESTED_CONTAINER`
are deprecated in favor of the new generally named agent APIs
`****_CONTAINER`.
* Agent flag `--executor_secret_key` has been deprecated. Operators
should use `--jwt_secret_key` instead.
