Without modifiers the returned value is string. When LEN is given the command returns the length of the result (i.e integer). When IDX is given the command returns a dictionary with the LCS length and all the ranges in both the strings, start and end offset for each string, where there are matches.

This abstract class provides a Python interface to all Redis commands and an implementation of the Redis protocol. Pipelines derive from this, implementing how the commands are sent and received to the Redis server. Based on configuration, an instance will either use a ConnectionPool, or Connection object to talk to redis. c K s t j|fi |��}| |d�S )a Return a Redis client object configured from the given URL For example:: redis://[[username]:[password]]@localhost:6379/0 rediss://[[username]:[password]]@localhost:6379/0 unix://[[username]:[password]]@/path/to/socket.sock?db=0 Three URL schemes are supported: - `redis://` creates a TCP socket connection. See more at: <https://www.iana.org/assignments/uri-schemes/prov/redis> - `rediss://` creates a SSL wrapped TCP socket connection. See more at: <https://www.iana.org/assignments/uri-schemes/prov/rediss> - ``unix://``: creates a Unix Domain Socket connection. The username, password, hostname, path and all querystring values are passed through urllib.parse.unquote in order to replace any percent-encoded values with their corresponding characters. There are several ways to specify a database number. The first value found will be used: 1. A ``db`` querystring option, e.g. redis://localhost?db=0 2. If using the redis:// or rediss:// schemes, the path argument of the url, e.g. redis://localhost/0 3. A ``db`` keyword argument to this function. If none of these options are specified, the default db=0 is used. All querystring options are cast to their appropriate Python types. Boolean arguments can be specified with string values "True"/"False" or "Yes"/"No". Values that cannot be properly cast cause a ``ValueError`` to be raised. Once parsed, the querystring arguments and keyword arguments are passed to the ``ConnectionPool``'s class initializer. In the case of conflicting arguments, querystring arguments always win. )�connection_pool)r �from_url)�cls�urlrc r r r r r V s *zRedis.from_urlZ localhosti� r Nzutf-8�strictF�requiredc& ' C s | s�| dur t �td�� | } |dur8t �td�� |} |du rJ|�t� ||#||| | ||t�|$�| |!|"|%d� }&| dur�|&�| td�� n@|&�|||||d�� |r�|&�t ||||||||| || | d� � t f i |&��} | | _ d| _ | r�| j � d �| _ t| jj�| _dS ) a4 Initialize a new Redis client.

If specified, ``timeout`` indicates a maximum life for the lock. By default, it will remain locked until release() is called. ``sleep`` indicates the amount of time to sleep per loop iteration when the lock is in blocking mode and another client is currently holding the lock. ``blocking`` indicates whether calling ``acquire`` should block until the lock has been acquired or to fail immediately, causing ``acquire`` to return False and the lock not being acquired. Defaults to True. Note this value can be overridden by passing a ``blocking`` argument to ``acquire``. ``blocking_timeout`` indicates the maximum amount of time in seconds to spend trying to acquire the lock. A value of ``None`` indicates continue trying forever. ``blocking_timeout`` can be specified as a float or integer, both representing the number of seconds to wait. ``lock_class`` forces the specified lock implementation. Note that as of redis-py 3.0, the only lock class we implement is ``Lock`` (which is a Lua-based lock). So, it's unlikely you'll need this parameter, unless you have created your own custom lock class. ``thread_local`` indicates whether the lock token is placed in thread-local storage. By default, the token is placed in thread local storage so that a thread only sees its token, not a token set by another thread. Consider the following timeline: time: 0, thread-1 acquires `my-lock`, with a timeout of 5 seconds. thread-1 sets the token to "abc" time: 1, thread-2 blocks trying to acquire `my-lock` using the Lock instance. time: 5, thread-1 has not yet completed. redis expires the lock key. time: 5, thread-2 acquired `my-lock` now that it's available. thread-2 sets the token to "xyz" time: 6, thread-1 finishes its work and calls release(). if the token is *not* stored in thread local storage, then thread-1 would see the token value as "xyz" and would be able to successfully release the thread-2's lock. In some use cases it's necessary to disable thread local storage. For example, if you have code where one thread acquires a lock and passes that lock instance to a worker thread to release later. If thread local storage isn't disabled in this case, the worker thread won't see the token set by the thread that acquired the lock. Our assumption is that these cases aren't common and as such default to using thread local storage.N)�timeoutrS �blocking�blocking_timeout� thread_localr )r* rl rV rS rW rX Z lock_classrY r r r �lockH s >�z Redis.lockc K s t | jfi |��S )z� Return a Publish/Subscribe object.

This is convenient for batch processing, such as saving all the values in a list to Redis. All commands executed within a pipeline are wrapped with MULTI and EXEC calls. This guarantees all commands executed in the pipeline will be executed atomically. Any command raising an exception does *not* halt the execution of subsequent commands in the pipeline. Instead, the exception is caught and its instance is placed into the response list returned by execute(). Code iterating over the response list should be able to deal with an instance of an exception as a potential value. In general, these will be ResponseError exceptions, such as those raised when issuing a command on a key of a different datatype. > �EXEC�DISCARD�UNWATCHc C s0 || _ d | _|| _|| _|| _d| _| �� d S )NF)r r6 r8 rJ rK �watchingr� )r* r r8 rJ rK r r r r. � s zPipeline.__init__c C s | S r! r r@ r r r r` s zPipeline.__enter__c C s | � � d S r! r� rc r r r rg s zPipeline.__exit__c C s$ z | � � W n ty Y n0 d S r! r� r@ r r r rh s zPipeline.__del__c C s t | j�S r! )r� � command_stackr@ r r r �__len__ s zPipeline.__len__c C s dS )z1Pipeline instances should always evaluate to TrueTr r@ r r r �__bool__ s zPipeline.__bool__c C s| g | _ t� | _| jrR| jrRz| j�d� | j�� W n tyP | j�� Y n0 d| _d| _ | jrx| j � | j� d | _d S )Nr� F) r� rj �scriptsr� r6 rm r| r rr �explicit_transactionr rj r@ r r r r� s zPipeline.resetc C s& | j rtd��| jr td��d| _ dS )z� Start a transactional block of the pipeline after WATCH commands are issued.
