PARTIAL_SCHEMAS =

These partial schemas are reused to build multiple request schemas

%w[target-any target-ssh target-winrm task].freeze
REQUEST_SCHEMAS =

These schemas combine shared schemas to describe client requests

%w[
  action-check_node_connections
  action-run_command
  action-run_task
  action-run_script
  action-upload_file
  transport-ssh
  transport-winrm
  connect-data
  action-apply_prep
  action-apply
].freeze
PE_BOLTLIB_PATH =

PE_BOLTLIB_PATH is intended to function exactly like the BOLTLIB_PATH used in Bolt::PAL. Paths and variable names are similar to what exists in Bolt::PAL, but with a 'PE' prefix.

'/opt/puppetlabs/server/apps/bolt-server/pe-bolt-modules'
DEFAULT_BOLT_CODEDIR =

For now at least, we maintain an entirely separate codedir from puppetserver by default, so that filesync can work properly. If filesync is not used, this can instead match the usual puppetserver codedir. See the `orchestrator.bolt.codedir` tk config setting.

#project_task_metadata(versioned_project, task_name_segments, job_id) ⇒ Object

This helper is responsible for computing or retrieving task metadata for a project. It expects task name in segments and uses the combination of task name and versioned_project as a unique identifier for caching in addition to the job_id. The job id is added to protect against a case where the buildtin content is update (where the apply_helpers would be managed)

#result_set_to_data(result_set, aggregate: false) ⇒ Object

Turns a Bolt::ResultSet object into a status hash that is fit to return to the client in a response. In the case of every action except check_node_connections the response will be a single serialized Result. In the check_node_connections case the response will be a hash with the top level “status” of the result and the serialized individual target results.

#with_pe_pal_init_settings(codedir, environmentpath, basemodulepath) ⇒ Object

This function is nearly identical to Bolt::Pal's `with_puppet_settings` with the one difference that we set the codedir to point to actual code, rather than the tmpdir. We only use this funtion inside the Modulepath initializer so that Puppet is correctly configured to pull environment configuration correctly. If we don't set codedir in this way: when we try to load and interpolate the modulepath it won't correctly load.

WARNING: THIS FUNCTION SHOULD ONLY BE CALLED INSIDE A SYNCHRONIZED PAL MUTEX
