||||
|
||||
This release contains new features, new benchmark plugins, bug fixes,
|

|
||||
|
||||
New Features
|
||||
~~~~~~~~~~~~
|
||||
|
||||
* rally task start **--abort-on-sla-failure**
|
||||
|
||||
Stopping load before things go wrong.
|
||||
Load generation will be interrupted if SLA criteria stop passing.
|
||||
|
||||
* Rally verify command supports multiple Tempest sources now.
|
||||
|
||||
* python34 support
|
||||
|
||||
* postgres DB backend support
|
||||
|
||||
|
||||
API changes
|
||||
~~~~~~~~~~~
|
||||
|
||||
|
||||
* [new] **rally [deployment | verify | task] use** subcommand
|
||||
|
||||
It should be used instead of root command **rally use**
|
||||
|
||||
* [new] Rally as a Lib API
|
||||
|
||||
To avoid code duplication between Rally as CLI tool and Rally as a Service
|
||||
we decide to make Rally as a Lib as a common part between these 2 modes.
|
||||
|
||||
Rally as a Service will be a daemon that just maps HTTP request to Rally
|
||||
as a Lib API.
|
||||
|
||||
* [deprecated] **rally use** CLI command
|
||||
|
||||
* [deprecated] Old Rally as a Lib API
|
||||
|
||||
Old Rally API was quite mixed up so we decide to deprecate it
|
||||
|
||||
|
||||
Plugins
|
||||
~~~~~~~
|
||||
|
||||
* **Benchmark Scenario Runners**:
|
||||
|
||||
[improved] Improved algorithm of generation load in **constant runner**
|
||||
|
||||
Before we used processes to generate load, now it creates pool of
|
||||
processes (amount of processes is equal to CPU count) after that in
|
||||
each process use threads to generate load. So now you can easily
|
||||
generate load of 1k concurrent scenarios.
|
||||
|
||||
[improved] Unify code of **constant** and **rps** runners
|
||||
|
||||
[interface] Added **abort()** to runner's plugin interface
|
||||
|
||||
New method **abort()** is used to immediately interrupt execution.
|
||||
|
||||
|
||||
* **Benchmark Scenarios**:
|
||||
|
||||
[new] DesignateBasic.create_and_delete_server
|
||||
|
||||
[new] DesignateBasic.create_and_list_servers
|
||||
|
||||
[new] DesignateBasic.list_servers
|
||||
|
||||
[new] MistralWorkbooks.list_workbooks
|
||||
|
||||
[new] MistralWorkbooks.create_workbook
|
||||
|
||||
[new] Quotas.neutron_update
|
||||
|
||||
[new] HeatStacks.create_update_delete_stack
|
||||
|
||||
[new] HeatStacks.list_stacks_and_resources
|
||||
|
||||
[new] HeatStacks.create_suspend_resume_delete_stac
|
||||
|
||||
[new] HeatStacks.create_check_delete_stack
|
||||
|
||||
[new] NeutronNetworks.create_and_delete_routers
|
||||
|
||||
[new] NovaKeypair.create_and_delete_keypair
|
||||
|
||||
[new] NovaKeypair.create_and_list_keypairs
|
||||
|
||||
[new] NovaKeypair.boot_and_delete_server_with_keypair
|
||||
|
||||
[new] NovaServers.boot_server_from_volume_and_live_migrate
|
||||
|
||||
[new] NovaServers.boot_server_attach_created_volume_and_live_migrate
|
||||
|
||||
[new] CinderVolumes.create_and_upload_volume_to_image
|
||||
|
||||
[fix] CinderVolumes.create_and_attach_volume
|
||||
|
||||
Pass optional **kwargs only to create server command
|
||||
|
||||
[fix] GlanceImages.create_image_and_boot_instances
|
||||
|
||||
Pass optional **kwargs only to create server command
|
||||
|
||||
[fix] TempestScenario.* removed stress cleanup.
|
||||
|
||||
Major issue is that tempest stress cleanup cleans whole OpenStack.
|
||||
This is very dangerous, so it's better to remove it and leave some
|
||||
extra resources.
|
||||
|
||||
[improved] NovaSecGroup.boot_and_delete_server_with_secgroups
|
||||
|
||||
Add optional **kwargs that are passed to boot server comment
|
||||
|
||||
|
||||
* **Benchmark Context**:
|
||||
|
||||
[new] **stacks**
|
||||
|
||||
Generates passed amount of heat stacks for all tenants.
|
||||
|
||||
[new] **custom_image**
|
||||
|
||||
Prepares images for benchmarks in VMs.
|
||||
|
||||
To Support generating workloads in VMs by existing tools like: IPerf,
|
||||
Blogbench, HPCC and others we have to have prepared images, with
|
||||
already installed and configured tools.
|
||||
|
||||
Rally team decide to generate such images on fly from passed to avoid
|
||||
requirements of having big repository with a lot of images.
|
||||
|
||||
This context is abstract context that allows to automate next steps:
|
||||
|
||||
1) runs VM with passed image (with floating ip and other stuff)
|
||||
2) execute abstract method that has access to VM
|
||||
3) snapshot this image
|
||||
|
||||
In future we are going to use this as a base for making context that
|
||||
prepares images.
|
||||
|
||||
[improved] **allow_ssh**
|
||||
|
||||
Automatically disable it if security group are disabled in neutron.
|
||||
|
||||
[improved] **keypair**
|
||||
|
||||
Key pairs are stored in "users" space it means that accessing keypair
|
||||
from scenario is simpler now:
|
||||
|
||||
self.context["user"]["keypair"]["private"]
|
||||
|
||||
[fix] **users**
|
||||
|
||||
Pass proper EndpointType for newly created users
|
||||
|
||||
[fix] **sahara_edp**
|
||||
|
||||
The Job Binaries data should be treated as a binary content
|
||||
|
||||
|
||||
* **Benchmark SLA**:
|
||||
|
||||
[interface] SLA calculations is done in additive way now
|
||||
|
||||
Resolves scale issues, because now we don't need to have whole
|
||||
array of iterations in memory to process SLA.
|
||||
|
||||
This is required to implement **--abort-on-sla-failure** feature
|
||||
|
||||
[all] SLA plugins were rewritten to implement new interface
|
||||
|
||||
|
||||
Bug fixes
|
||||
~~~~~~~~~
|
||||
|
||||
**18 bugs were fixed, the most critical are**:
|
||||
|
||||
|
||||
* Fix **rally task detailed --iterations-data**
|
||||
|
||||
It didn't work in case of missing atomic actions. Such situation can occur
|
||||
if scenario method raises exceptions
|
||||
|
||||
* Add user-friendly message if the task cannot be deleted
|
||||
|
||||
In case of trying to delete task that is not in "finished" status users get
|
||||
traces instead of user-friendly message try to run it with --force key.
|
||||
|
||||
|
||||
* Network context cleanups networks properly now
|
||||
|
||||
|
||||
Documentation
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
* Image sizes are fixed
|
||||
|
||||
* New tutorial in "Step by Step" relate to **--abort-on-sla-failure**
|
||||
|
||||
* Various fixes
