示例1: generate_reports
# 需要导入模块: from intelmq.lib.message import Report [as 别名]
# 或者: from intelmq.lib.message.Report import copy [as 别名]
def generate_reports(report_template: Report, infile: BinaryIO, chunk_size: Optional[int],
copy_header_line: bool) -> Generator[Report, None, None]:
"""Generate reports from a template and input file, optionally split into chunks.
If chunk_size is None, a single report is generated with the entire
contents of infile as the raw data. Otherwise chunk_size should be
an integer giving the maximum number of bytes in a chunk. The data
read from infile is then split into chunks of this size at newline
characters (see read_delimited_chunks). For each of the chunks, this
function yields a copy of the report_template with that chunk as the
value of the raw attribute.
When splitting the data into chunks, if copy_header_line is true,
the first line the file is read before chunking and then prepended
to each of the chunks. This is particularly useful when splitting
CSV files.
The infile should be a file-like object. generate_reports uses only
two methods, readline and read, with readline only called once and
only if copy_header_line is true. Both methods should return bytes
objects.
Params:
report_template: report used as template for all yielded copies
infile: stream to read from
chunk_size: maximum size of each chunk
copy_header_line: copy the first line of the infile to each chunk
Yields:
report: a Report object holding the chunk in the raw field
