The 'logger' object is dill's top-level logger. The 'adapter' object wraps the logger and implements a 'trace()' method that generates a detailed tree-style trace for the pickling call at log level INFO. The 'trace()' function sets and resets dill's logger log level, enabling and disabling the pickling trace. The trace shows a tree structure depicting the depth of each object serialized *with dill save functions*, but not the ones that use save functions from 'pickle._Pickler.dispatch'. If the information is available, it also displays the size in bytes that the object contributed to the pickle stream (including its child objects). Sample trace output: >>> import dill, dill.tests >>> dill.detect.trace(True) >>> dill.dump_session(main=dill.tests) ┬ M1: <module 'dill.tests' from '.../dill/tests/__init__.py'> ├┬ F2: <function _import_module at 0x7f0d2dce1b80> │└ # F2 [32 B] ├┬ D2: <dict object at 0x7f0d2e98a540> │├┬ T4: <class '_frozen_importlib.ModuleSpec'> ││└ # T4 [35 B] │├┬ D2: <dict object at 0x7f0d2ef0e8c0> ││├┬ T4: <class '_frozen_importlib_external.SourceFileLoader'> │││└ # T4 [50 B] ││├┬ D2: <dict object at 0x7f0d2e988a40> │││└ # D2 [84 B] ││└ # D2 [413 B] │└ # D2 [763 B] └ # M1 [813 B] )�adapter�logger�trace� N)�partial)�TextIO�Union�|�+�`)� │u ├� ┬� └c @ s@ e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dS )� TraceAdaptera� Tracks object tree depth and calculates pickled object size. A single instance of this wraps the module's logger, as the logging API doesn't allow setting it directly with a custom Logger subclass. The added 'trace()' method receives a pickle instance as the first argument and creates extra values to be added in the LogRecord from it, then calls 'info()'. Usage of logger with 'trace()' method: >>> from dill.logger import adapter as logger #NOTE: not dill.logger.logger >>> ... >>> def save_atype(pickler, obj): >>> logger.trace(pickler, "Message with %s and %r etc. placeholders", 'text', obj) >>> ... c C s || _ d S �N)r )�selfr � r �{/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/dill/logger.py�__init__t s zTraceAdapter.__init__c C s& t d|d�}|�|� | j�|� d S )Nz %(prefix)s%(message)s%(suffix)s��handler)�TraceFormatter� setFormatterr � addHandler)r r � formatterr r r r v s zTraceAdapter.addHandlerc C s | j �|� d S r )r � removeHandler)r r r r r r z s zTraceAdapter.removeHandlerc C s ||fS r r )r �msg�kwargsr r r �process| s zTraceAdapter.processc C s8 t jj|dd�sd S | �tj�r.d|_g |_nd |_d S )NF)�child� )�dillZ_dillZis_dill� isEnabledFor�logging�INFO� _trace_depth� _size_stack)r �picklerr r r � trace_setup s zTraceAdapter.trace_setupc O s0 t |d�s&tj|g|�R i |�� d S |jd u r4d S |�di �}|�d�}d }zF|j�� }|jj }z||�� 7 }W n t y� |t |�7 }Y n0 W n t t fy� Y n0 |d ur�|s�|j �|� n||j �� 8 }||d< |r�| jd8 _|j|d< ||d< | j|g|�R i |�� |�s,| jd7 _d S )Nr$ �extra�#�sizer �depth)�hasattrr �infor$ �get� startswith�_file�tell�framer� current_frame�AttributeError�len� TypeErrorr% �append�pop) r r& r �argsr r( Z pushed_objr* �framer r r r � s: zTraceAdapter.traceN) �__name__� __module__� __qualname__�__doc__r r r r r' r r r r r r b s r c s2 e Zd ZdZdd�� fdd� Z� fdd�Z� ZS )r z� Generates message prefix and suffix from record.

Example usage: >>> import dill >>> dill.detect.trace(True) >>> dill.dump_session() Alternatively, ``trace()`` can be used as a context manager. With no arguments, it just takes care of restoring the tracing state on exit. Either a file handle, or a file name and (optionally) a file mode may be specitfied to redirect the tracing output in the ``with`` block context. A log function is yielded by the manager so the user can write extra information to the file. Example usage: >>> from dill import detect >>> D = {'a': 42, 'b': {'x': None}} >>> with detect.trace(): >>> dumps(D) ┬ D2: <dict object at 0x7f2721804800> ├┬ D2: <dict object at 0x7f27217f5c40> │└ # D2 [8 B] └ # D2 [22 B] >>> squared = lambda x: x**2 >>> with detect.trace('output.txt', mode='w') as log: >>> log("> D = %r", D) >>> dumps(D) >>> log("> squared = %r", squared) >>> dumps(squared) Arguments: arg: a boolean value, or an optional file-like or path-like object for the context manager mode: mode string for ``open()`` if a file name is passed as the first argument )�False�True)�filera N)�repr� TraceManagerr �setLevelr" r# �WARNING)rb ra r r r r � s ' r c @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) rh zDcontext manager version of trace(); can redirect the trace to a filec C s& || _ || _|d u| _t|d�| _d S )N�write)rf ra �redirectr, �file_is_stream)r rf ra r r r r s zTraceManager.__init__c C sh | j rLt�� | jr$t�| j�| _nt�| j| j �| _t � t� t � | j� t � � | _t �tj� t jS r )rl �stderr_handler�flushrm r" � StreamHandlerrf r � FileHandlerra r r r �getEffectiveLevel� old_levelri r# r- )r r r r � __enter__ s zTraceManager.__enter__c G s< t �| j� | jr8t �| j� t �t� | js8| j� � d S r ) r ri rs rl r r r rn rm �close)r �exc_infor r r �__exit__ s zTraceManager.__exit__N)r; r< r= r> r rt rw r r r r rh s rh )N)!r> �__all__rD � contextlibrB r" rW �os� functoolsr �typingr r r �str� maketransrU � LoggerAdapterr � Formatterr � getLoggerr � propagater �_StderrHandlerrn r �bool�PathLiker �AbstractContextManagerrh r r r r �<module> s( $ (H) (+
