Every shared memory block is assigned a unique name. This enables one process to create a shared memory block with a particular name so that a different process can attach to that same shared memory block using that same name. As a resource for sharing data across processes, shared memory blocks may outlive the original process that created them. When one process no longer needs access to a shared memory block that might still be needed by other processes, the close() method should be called. When a shared memory block is no longer needed by any process, the unlink() method should be called to ensure proper cleanup.N���i� TFr c C s� |dkst d��|r0ttjB | _|dkr0t d��|d u rL| jtj@ sLt d��t�rD|d u r�t� }ztj || j| j d�| _ W n t y� Y qZY n0 || _ q�qZn.| jr�d| n|}tj || j| j d�| _ || _ z<|r�|r�t�| j |� t�| j �}|j}t�| j |�| _W n t�y& | �� � Y n0 ddlm} || j d � �n*|�r |d u �rZt� n|}t�tjtjtj |d ? d @ |d @ |�}zjt� � }|tj k�r�|d u�r�t t j t�!t j �|tj ��nW t�"|� �qJtjd ||d �| _W t�"|� n t�"|� 0 || _ �qn�qJnb|| _ t�#tj$d|�}z"t�%|tj$ddd�} W t�"|� n t�"|� 0 t�&| �}tjd ||d �| _|| _'t(| j�| _)d S )Nr z!'size' must be a positive integerz4'size' must be a positive number different from zeroz&'name' can only be None if create=True)�mode�/� )�register� shared_memory� l �� r )ZtagnameF)*� ValueError�_O_CREX�os�O_RDWR�_flags�O_EXCL� _USE_POSIXr � _posixshmemZshm_open�_mode�_fd�FileExistsError�_name�_prepend_leading_slash� ftruncate�fstat�st_size�mmap�_mmap�OSError�unlink�resource_trackerr �_winapiZCreateFileMappingZINVALID_HANDLE_VALUEZNULLZPAGE_READWRITEZ GetLastErrorZERROR_ALREADY_EXISTS�errno�EEXIST�strerrorZ CloseHandleZOpenFileMappingZ FILE_MAP_READZ MapViewOfFileZVirtualQuerySize�_size� memoryview�_buf) �selfr �create�sizeZstatsr Z temp_nameZh_mapZlast_error_codeZp_bufr r r �__init__J s� � � � � � �� zSharedMemory.__init__c C s$ z | � � W n ty Y n0 d S �N)�closer* �r4 r r r �__del__� s zSharedMemory.__del__c C s | j | jd| jffS )NF)� __class__r r6 r: r r r � __reduce__� s ��zSharedMemory.__reduce__c C s | j j� d| j�d| j� d�S )N�(z, size=�))r< �__name__r r6 r: r r r �__repr__� s zSharedMemory.__repr__c C s | j S )z4A memoryview of contents of the shared memory block.)r3 r: r r r �buf� s zSharedMemory.bufc C s. | j }tr*| jr*| j �d�r*| j dd� }|S )z4Unique name that identifies the shared memory block.r r N)r# r r$ � startswith)r4 Z reported_namer r r r � s zSharedMemory.namec C s | j S )zSize in bytes.)r1 r: r r r r6 � s zSharedMemory.sizec C sX | j dur| j �� d| _ | jdur4| j�� d| _trT| jdkrTt�| j� d| _dS )zkCloses access to the shared memory from this instance but does not destroy the shared memory block.Nr r )r3 �releaser) r9 r r! r r: r r r r9 � s zSharedMemory.closec C s2 t r.| jr.ddlm} t�| j� || jd� dS )z�Requests that the underlying shared memory block be destroyed.

It differs from the built-in list type in that these lists can not change their overall length (i.e. no append, insert, etc.) Because values are packed into a memoryview as bytes, the struct packing format for any storable value must require no more than 8 characters to describe its format.�q�dzxxxxxxx?z%dsNzxxxxxx?x� c C s | S r8 r ��valuer r r �<lambda> � zShareableList.<lambda>c C s | � d��t�S �N� )�rstrip�decode� _encodingrN r r r rP rQ c C s | � d�S rR )rT rN r r r rP rQ c C s d S r8 r )�_valuer r r rP rQ )r r r � c C s: t | ttdjf�sdS t | t�r$dS t | t�r2dS dS dS )z�Used in concert with _back_transforms_mapping to convert values into the appropriate Python objects when retrieving them from the list as well as when storing them.Nr r r rX )� isinstance�str�bytesr< rN r r r �_extract_recreation_code s z&ShareableList._extract_recreation_code�r c s� |d u s|d ur�|pd}�fdd�|D �}t |��_d}dg�_|D ]6}||d dkr\�jnt|d d� �7 }�j�|� qD�fdd�|D �}t�d�j d � |� �j �j �}t |d |d ��_ n t |��_ |d u�r�t� tjd�j �j jd�jg�j�R � tjd � |��j j�jg� fd d �|D ��R � tj�j �j j�jg� fdd �|D ��R � tj�j �j j�jg|�R � n$t ���_tt��j�j jd���_d S )Nr c sP g | ]H}t |ttf�s$� jt|� n&� jt|� � jt|�� j d f �qS )r )rY rZ r[ �_types_mapping�type� _alignmentr ��.0�itemr: r r � <listcomp>+ s � � �z*ShareableList.__init__.<locals>.<listcomp>r r �sc s g | ]}� � |��qS r )r\ ra r: r r rd = s rK � T)r5 r6 c 3 s& | ] }t |t�r|�� �n|V qd S r8 )rY rZ �encode�rb �v��_encr r � <genexpr>X rQ z)ShareableList.__init__.<locals>.<genexpr>c 3 s | ]}|� � �V qd S r8 )rg rh rj r r rl ^ rQ rM )r � _list_len�_allocated_offsetsr` �int�append�struct�calcsize�_format_size_metainfo�join�_format_packing_metainfo� _format_back_transform_codesr �shmrV � pack_intorB �_offset_data_start�_offset_packing_formats� _offset_back_transform_codes�list� unpack_from)r4 Zsequencer Z_formats�offset�fmtZ_recreation_codesZrequested_sizer )rk r4 r r7 ( s� � & ����� �������� ��zShareableList.__init__c C sj |dkr |n|| j }|| j ks*| j dk r2td��t�d| jj| j|d �d }|�d�}|�t �}|S )z>Gets the packing format for a single value stored in the list.r � Requested position out of range.�8srM rS ) rm � IndexErrorrq r} rw rB rz rT rU rV )r4 �positionri r � fmt_as_strr r r �_get_packing_formatq s �� z!ShareableList._get_packing_formatc C sF || j ks| j dk r td��t�d| jj| j| �d }| j| }|S )z9Gets the back transformation function for a single value.r r� �b)rm r� rq r} rw rB r{ �_back_transforms_mapping)r4 r� �transform_codeZtransform_functionr r r �_get_back_transform� s �� z!ShareableList._get_back_transformc C sh || j ks| j dk r td��t�d| jj| j|d |�t�� | � |�}t�d| jj| j | |� dS )zvSets the packing format and back transformation code for a single value in the list at the specified position.r r� r� rM r� N) rm r� rq rx rw rB rz rg rV r\ r{ )r4 r� r� rO r� r r r �!_set_packing_format_and_transform� s � �z/ShareableList._set_packing_format_and_transformc C sv |dkr |n|| j }z.| j| j| }t�| �|�| jj|�\}W n ty^ td��Y n0 | � |�}||�}|S )Nr zindex out of range) rm ry rn rq r} r� rw rB r� r� )r4 r� r~ ri Zback_transformr r r � __getitem__� s � zShareableList.__getitem__c C s� |dkr |n|| j }z"| j| }| j| }| �|�}W n tyR td��Y n0 t|ttf�sv| jt |� }|}n`| j|d | }t|t�r�|� t �n|}t |�|kr�t d��|d dkr�|}n| jt |f }| �|||� t�|| jj||� d S )Nr z assignment index out of ranger z(bytes/str item exceeds available storager re )rm rn ry r� r� rY rZ r[ r^ r_ rg rV r r r� rq rx rw rB ) r4 r� rO Z item_offsetr~ Zcurrent_formatZ new_formatZ encoded_valueZallocated_lengthr r r � __setitem__� s8 � � ��zShareableList.__setitem__c C s t | j| jjd�dfS )Nr] r )r r< rw r r: r r r r= � s zShareableList.__reduce__c C s t �d| jjd�d S )NrK r )rq r} rw rB r: r r r �__len__� s zShareableList.__len__c C s" | j j� dt| �� d| jj�d�S )Nr> z, name=r?
