parse_line

✓ from line_protocol_parser import parse_line

parse_lines

✓ from line_protocol_parser import parse_lines

Parse a single line protocol string.

from line_protocol_parser import parse_line line = 'weather,location=us-midwest temperature=82 1465839830100400200' result = parse_line(line) print(result) # {'measurement': 'weather', 'tags': {'location': 'us-midwest'}, 'fields': {'temperature': 82}, 'timestamp': 1465839830100400200, 'has_time': True}

Debug

Known issues

breakingIn version 2.0.0, omitted timestamps now yield None for timestamp and has_time=False, instead of timestamp=0. Check code that assumed explicit 0 for missing timestamps.

fix

Update logic that compares timestamp to 0; use has_time field to distinguish.

affects: >=2.0.0

breakingDuplicate tags within a single line are now rejected as malformed. Previously, the last tag might silently override earlier ones.

fix

Ensure no duplicate tag keys in input lines.

affects: >=2.0.0

gotchaParser is strict about key/value formatting: tag keys and field keys must not start with underscore, must be valid identifiers, etc. Invalid lines raise ValueError.

fix

Sanitize line protocol strings before parsing.

affects: >=2.0.0

Errors

Common errors & fixes

ValueError: Invalid line protocol: duplicate tag key 'location'

The input line contains the same tag key more than once.

fix

Remove duplicate tag keys from the line.

ValueError: Invalid line protocol: unexpected trailing characters

Extra whitespace or characters after the timestamp or at end of line.

fix

Trim trailing whitespace or ensure line ends after valid timestamp.

ValueError: Invalid line protocol: missing measurement name

Line is empty or starts with a comma or space.

fix

Ensure line starts with a valid measurement name.

AttributeError: module 'line_protocol_parser' has no attribute 'parse_line'

Trying to import from a wrong package name (e.g., 'line_protocol_parser' vs 'line-protocol-parser').

fix

Install correct package: pip install line-protocol-parser
