• Fix instance joining when a leader is not first

1.10.0 - more than alive

Added

• wait_members_alive step to wait until all cluster members have alive status
  and specified state;
• wait_cluster_has_no_issues step to wait until cluster has no issues
• Availability to upload ZIP configs to TDG;
• cartridge_not_save_cookie_in_app_config variable that allows to disable persisting cluster
  cookie in the application configuration file;

• Variables bootstrap_vshard_retries, bootstrap_vshard_delay, connect_to_membership_retries,
  connect_to_membership_delay to change hardcoded values.

Changed

• Timeout instance_start_timeout (to check that all instances become started)
  deprecated and replaced with instance_start_retries and instance_start_delay;
• Timeout instance_discover_buckets_timeout (to check that instances discover buckets)
  deprecated and replaced with instance_discover_buckets_retries and instance_discover_buckets_delay.

Fixed

• Fail on getting control instance when all unjoined instances haven't
  replicaset_alias set;
• Support of Ansible 4.0 (Ansible Core 2.11);
• Handling of bad membership members - empty or with empty payload.

1.9.0 - closer to reality

Bug fixes

• Running the role with python 2.7
• Skipping instances restart when package was updated, but configuration wasn't
• Missing default config for machine with stateboard
• Specifying cartridge_app_name other than the TGZ package name
• Creating unnamed replicasets with instances without replicaset_alias set
• Getting control instance:
  • Now one not expelled instance should also be alive; it's checked
    by creating connection using instances advertise URIs
  • Control instance should be alive
  • If there are some joined instances, but no one of them isn't alive,
    getting control instance fails.
• set_control_instance is improved to consider non-joined instance status
• edit_topology step now considers roles dependencies, permanent and hidden roles
  and don't perform unnecessary calls if enabled roles list isn't changed

Features

• failover_promote step to promote replicasets leaders
• Allowed to skip user and group creation for tgz
• Debug control instance and one not expelled instance
• Timeouts for two-phase commits:
  • twophase_netbox_call_timeout
  • twophase_upload_config_timeout
  • twophase_apply_config_timeout
• eval and eval_on_control_instance steps to eval code on instances
• Step stop_instance to stop and disable instance systemd service
• Step start_instance to start and enable instance systemd service
• Step restart_instance_force to restart systemd service without any conditions
• New cartridge_failover_params fields:
  • failover_timeout
  • fencing_enabled
  • fencing_timeout
  • fencing_pause
• edit_topology_allow_missed_instances variable to allow replicasets containing
  the instances that are not started yet
• upload_app_config step to load the file or directory config
  (Cartridge and TDG are supported)

Changes

• Timeout to wait for cluster health after topology editing
  renamed from edit_topology_timeout to edit_topology_healthy_timeout
• cartridge_cluster_cookie now is required only for configure_instance,
  restart_instance and upload_app_config steps

1.8.3 - even faster and more stable

Bug fixes

• Role variables are saved to the dictionary, so they do not affect the next play

Changes

• Now only the necessary information will be transferred in tasks,
  which used hostvars. Due to this duration of these tasks was reduced.

1.8.2 - variables got better

Bug fixes

• Fix facts setting in hostvars fact

1.8.1 - not only better but also compatible

Bug fixes

• Removing stateboard instance distribution directory on rotate_dists step
• Fixed fail on getting one non-expelled instance when only stateboard instance
  is configured
• Fixed compatibility with Ansible 2.8 and 2.9
• Use playbook variables in tasks that use hostsvars

1.8.0 - scenarios and boost

Bug fixes

• Role installation will be completely skipped
  if you specify a tag other than the tags for this role
• Fixed selecting control instance that doesn't belong to cluster or isn't alive.
  The following rules are currently used:
  • Members are checked in lexicographic order by URIs
  • Members not mentioned in hostvars aren't selected to be control
  • Members with status not alive aren't selected to be control
• Fixed setting needs_restart when configuration files don't exist
• Fixed error on configuring auth without users specified
• Reset role variables before each run

Features

• cartridge-replicasets tag added to the membership stage
• cartridge_wait_buckets_discovery parameter to wait for instance to discover buckets
• instance_discover_buckets_timeout parameter to configure time in seconds
  to wait for instance to discover buckets
• Ability to deploy TGZ packages
• cartridge_multiversion flag that allows to use specific version of application
  for each instance and perform rolling update correctly (using new update_instance step)
• rotate_dists step that allows to rotate application distributions
• cleanup step to remove temporary files from specific list
• Added availability to import steps by scenario name. Added some default scenarios.
  Added availability to create custom scenarios.
• availability to use tasks_from to import any step
• zone variable to edit instance zone
• edit_topology_timeout variable to wait until cluster become healthy
  after editing topology
• availability to specify instance memtx_dir, vinyl_dir and wal_dir params
  by cartridge_memtx_dir_parent, cartridge_vinyl_dir_parent, cartridge_wal_dir_parent variables.
• Control instance is selected considering two-phase commit version of instances.
  The reason is that all operations that modify cluster-wide config should be performed via instance
  that has lowest Cartridge version (in fact, only two-phase commit version matters).
• Availability to change advertise URIs of any instance

Changes

• cartridge.admin_edit_topology is called once for all replicasets and instances
  to expel. It can be called second time to set up failover priority for
  replicasets where new instances were joined.
  As a result, replicaset_healthy_timeout is removed as unused.
• Now list of instances for installing a package is selected once for all.
  Before this patch, the complexity of calculating the list of instances was O(N^2),
  now it is O(N). For 100 instances, it gives a 10x time reduction (60s -> 5s).
• Refactored package installing. Getting package info is performed in a library module,
  all tasks except installing package itself are common for RPM and DEB.
• Now check_instance_started function: check all instances, including the stateboard;
  wait Unconfigured or RolesConfigured status instead alive state; check that
  all buckets are discovered by routers if cluster was bootstrapped.
• Role divided into many steps. It's possible to combine them using a scenario
  in the config by cartridge_scenario. It is also possible to use custom steps in a scenario.
  Custom steps can be defined by cartridge_custom_steps_dir and cartridge_custom_steps.
• Now step connect_to_membership is executed only on one not expelled instance.
  Before the patch, the difficulty of performing connect_to_membership step was N^2.
  For 100 instances, the step took about 900 seconds. Now the complexity has decreased to N,
  so for 100 instances the execution time is about 5 seconds.

Fixed

• needs_restart task error for non-bootstrapped instance

Added

• replicaset_healthy_timeout parameter to wait for replicaset to be
  healthy after editing it
