Seeks file to next chunk delimiter, where chunks are defined on file start, a delimiting sequence, and file end. Use file.tell() to see location afterwards. Note that file start is a valid split, so must be at offset > 0 to seek for delimiter. Parameters ---------- file: a file delimiter: bytes a delimiter like ``b'\n'`` or message sentinel, matching file .read() type blocksize: int Number of bytes to read from the file at once. Returns ------- Returns True if a delimiter was found, False if at file start or end. rFNT)tellreadindexseeklenOSError ValueError)r delimiter blocksizelastcurrentfullrRs r8seek_delimiterris. yy{aD ))I&!%tg~7 D JJy) $))+TQ7#i.HIW )* S^O%&! $   sAB&B&&B87B8c|r|j|t||d}||jS|j}|||z z}|j||zt||d}|j}|r|r|t |z}|r|r|t |z}|}||z }|j||J|j|} | S)aRead a block of bytes from a file Parameters ---------- f: File Open file offset: int Byte offset to start read length: int Number of bytes to read, read through end of file if None delimiter: bytes (optional) Ensure reading starts and stops at delimiter bytestring split_before: bool (optional) Start/stop read *before* delimiter bytestring. If using the ``delimiter=`` keyword argument we ensure that the read starts and stops at delimiter boundaries that follow the locations ``offset`` and ``offset + length``. If ``offset`` is zero then we start at zero, regardless of delimiter. The bytestring returned WILL include the terminating delimiter string.

For backwards compatibility with older Python version, pathlib.Path objects are specially coerced. Any other object is passed through unchanged, which includes bytes, strings, buffers, or anything else that's not even path-like. __fspath__r) isinstancerPhasattrr~r)filepaths r8stringify_pathrIsE,(C  < (""$$ 6 "}}r:c6||i|}|j|SrO)_determine_worker)clsryrzinsts r8 make_instanceris$   D Kr:c|Dcgc]}|jdc}tdD}d}t|D]tfdD}|rn|z dj ddScc}w)z;For a list of paths, find the shortest prefix common to all/c32K|]}t|ywrO)ra).0ps r8 z common_prefix..ts%!s1v%rc3:K|]}|dk(yw)rN)rrrRpartss r8rz common_prefix..ws"5!!A$%(1+%5sN)splitminrangeallr,)pathsrlmaxrrrRrs @@r8 common_prefixrqs#( )aQWWS\ )E %u% %D C 4[5u55 HA 88E!HRaL !! *sA;c t|tr|jd}|r4|Dcgc]'}dj||j ddf)}}|St |}|r|j ddd}|s4td|Dr"|Dcgc]}dj||g}}|S|Dcgc]}|j||d}}|St|t|k(sJ|Scc}wcc}wcc}w)aIn bulk file operations, construct a new file tree from a list of files Parameters ---------- paths: list of str The input file tree path2: str or list of str Root to construct the new list in.
