"""Git LFS related utilities""" import io import os from contextlib import AbstractContextManager from typing import BinaryIO class SliceFileObj(AbstractContextManager): """ Utility context manager to read a *slice* of a seekable file-like object as a seekable, file-like object. This is NOT thread safe Inspired by stackoverflow.com/a/29838711/593036 Credits to @julien-c Args: fileobj (`BinaryIO`): A file-like object to slice. MUST implement `tell()` and `seek()` (and `read()` of course). `fileobj` will be reset to its original position when exiting the context manager. seek_from (`int`): The start of the slice (offset from position 0 in bytes). read_limit (`int`): The maximum number of bytes to read from the slice. Attributes: previous_position (`int`): The previous position Examples: Reading 200 bytes with an offset of 128 bytes from a file (ie bytes 128 to 327): ```python >>> with open("path/to/file", "rb") as file: ... with SliceFileObj(file, seek_from=128, read_limit=200) as fslice: ... fslice.read(...) ``` Reading a file in chunks of 512 bytes ```python >>> import os >>> chunk_size = 512 >>> file_size = os.getsize("path/to/file") >>> with open("path/to/file", "rb") as file: ... for chunk_idx in range(ceil(file_size / chunk_size)): ... with SliceFileObj(file, seek_from=chunk_idx * chunk_size, read_limit=chunk_size) as fslice: ... chunk = fslice.read(...) ``` """ def __init__(self, fileobj: BinaryIO, seek_from: int, read_limit: int): self.fileobj = fileobj self.seek_from = seek_from self.read_limit = read_limit def __enter__(self): self._previous_position = self.fileobj.tell() end_of_stream = self.fileobj.seek(0, os.SEEK_END) self._len = min(self.read_limit, end_of_stream - self.seek_from) # ^^ The actual number of bytes that can be read from the slice self.fileobj.seek(self.seek_from, io.SEEK_SET) return self def __exit__(self, exc_type, exc_value, traceback): self.fileobj.seek(self._previous_position, io.SEEK_SET) def read(self, n: int = -1): pos = self.tell() if pos >= self._len: return b"" remaining_amount = self._len - pos data = self.fileobj.read(remaining_amount if n < 0 else min(n, remaining_amount)) return data def tell(self) -> int: return self.fileobj.tell() - self.seek_from def seek(self, offset: int, whence: int = os.SEEK_SET) -> int: start = self.seek_from end = start + self._len if whence in (os.SEEK_SET, os.SEEK_END): offset = start + offset if whence == os.SEEK_SET else end + offset offset = max(start, min(offset, end)) whence = os.SEEK_SET elif whence == os.SEEK_CUR: cur_pos = self.fileobj.tell() offset = max(start - cur_pos, min(offset, end - cur_pos)) else: raise ValueError(f"whence value {whence} is not supported") return self.fileobj.seek(offset, whence) - self.seek_from def __iter__(self): yield self.read(n=4 * 1024 * 1024)
