Unlike :func:`run_dict`, which shells out to a ``powershell.exe`` subprocess, this class opens an **in-process** runspace and keeps it alive across multiple calls. The same runspace is reused for every ``run*`` invocation, so imported modules, loaded functions, and session variables persist for the lifetime of the object. **Requirements:** both :data:`HAS_CLR` and :data:`HAS_PWSH_SDK` must be ``True`` before instantiating this class. **Usage — always use as a context manager** so the underlying runspace is disposed of deterministically:: with PowerShellSession() as session: result = session.run_json("Get-NetAdapter | Select-Object Name, Status") **Methods:** * :meth:`run` — run a script and return raw Python scalars/lists. * :meth:`run_json` — run a script and return a parsed Python object via ``ConvertTo-Json``. * :meth:`run_strict` — like :meth:`run` but raises :exc:`~salt.exceptions.CommandExecutionError` if the script did not run to completion (i.e., an uncaught error occurred). **Session defaults** set in :meth:`__init__`: * ``$ErrorActionPreference = 'Stop'`` — all non-terminating cmdlet errors are promoted to terminating exceptions so they cannot be silently ignored. * ``$ProgressPreference = 'SilentlyContinue'`` — suppresses progress bars that would otherwise pollute the output stream. * ``$WarningPreference = 'SilentlyContinue'`` — suppresses advisory warnings that are not actionable in an automation context. c C sH t �� | _| j�d��� | j�d��� | j�d��� | j�� dS )a� Create the PowerShell runspace and apply session-wide preferences. Sets ``$ErrorActionPreference = 'Stop'`` so every cmdlet uses terminating-error semantics by default. Individual commands that are expected to return nothing (e.g., ``Get-NetRoute`` when no route exists) must use ``-ErrorAction SilentlyContinue`` or be wrapped in a PowerShell ``try/catch`` block. z($ProgressPreference = 'SilentlyContinue'z $ErrorActionPreference = 'Stop'z'$WarningPreference = 'SilentlyContinue'N)r ZCreate�ps� AddScript� AddStatement�Invoke��selfr r r �__init__x s zPowerShellSession.__init__c C s | S �Nr r' r r r � __enter__� s zPowerShellSession.__enter__c C s | � d�S )Nz$$PSVersionTable.PSVersion.ToString())�runr' r r r �version� s zPowerShellSession.versionNc C s^ |sdS | j j�� | j j�� t|t�r|n|gD ] }| j �d|� ���� q| j � � dS )z8 Load modules into the existing session NzImport-Module ) r# �Commands�Clear�Streams� ClearStreamsr r r$ r% r& )r( r �moduler r r �import_modules� s z PowerShellSession.import_modulesc C s� | j j�� | j j�� | j �|� | j �� }| j jrDd}| j jjj dkr/| j jjd � � }n | j j j r<t | j j j j�}t�d|� |S |rLt|�dkrNdS t|�dkrp|d }|du r^dS |j}t|t tttf�rl|S t |�S dd� |D �S )a_ Run a PowerShell command and return the result without attempting to parse it convert the PowerShell objects.

Unless the command already contains ``ConvertTo-Json``, the method automatically pipes the output through ``ConvertTo-Json -Compress -Depth <depth>`` and then ``Out-String`` before parsing. This ensures that PowerShell objects are always serialized to English-language JSON regardless of the system locale. Args: cmd (str): The PowerShell command or script to run. depth (int): The JSON serialization depth passed to ``ConvertTo-Json``. Defaults to ``4``. Returns: Any: The deserialized Python object (dict, list, str, etc.), or ``None`` if PowerShell produced no output.

Identical to :meth:`run` except that a ``CommandExecutionError`` is raised when PowerShell reports ``HadErrors``, rather than logging and returning the error string. Use this when the caller must not silently continue after a failure (e.g., when executing a large configuration script where a mid-script error would leave the system in an unknown state). .. note:: PowerShell sets ``HadErrors = True`` even for errors caught by ``try/catch`` inside the script. To distinguish "script ran to completion with some suppressed errors" from "script terminated mid-way", we bracket the caller's script with a sentinel variable. If the sentinel is ``$true`` at the end, all errors were caught intentionally and we do not raise. Args: cmd (str): The PowerShell command or script to run. Returns: str | list | None: Same return types as :meth:`run`. Raises: CommandExecutionError: If PowerShell reports any error. z$__salt_ok__ = $false z $__salt_ok__ = $truer Nz$__salt_ok__ -eq $true�truer4 zCif ($Error.Count -gt 0) { $Error[0].Exception.Message } else { '' }r5 c S r6 r r7 r8 r r r r; a r< z0PowerShellSession.run_strict.<locals>.<listcomp>)r# r. r/ r0 r1 r$ r& r= r> r? r@ rA rB r r rC �stripr rF rG r rH rI rJ ) r( r �wrappedrK Z streams_errZ inv_reasonZchkZ ran_to_endrL Z err_results�msgrM rN r r r � run_strict s\ �� "� �� z PowerShellSession.run_strictc C s( |r t �d|� t �|� | j�� dS )z� exc_type: The class of the exception (e.g., CommandExecutionError) exc_val: The instance of the exception exc_tb: The traceback object z*PowerShellSession exiting due to error: %sN)rD rE r# ZDispose)r( �exc_typeZexc_valZexc_tbr r r �__exit__c s zPowerShellSession.__exit__r* )rO ) �__name__� __module__� __qualname__�__doc__r) r+ r- r3 r, rW r\ r^ r r r r r" Q s & 35 ]r" r* )�loggingrQ Zsalt.modules.cmdmodr Zsalt.utils.jsonZsalt.exceptionsr � getLoggerr_ rD ZHAS_CLRZclr� ImportErrorrE Z HAS_PWSH_SDKZ PWSH_GAC_NAMEZ AddReferenceZ System.Management.Automationr � Exception�excr! r" r r r r �<module> s2 � �� 3
