[!] version %r is not 'major.minor[.patch]'

Error message

[!] version %r is not 'major.minor[.patch]'

What it means

series() reduces a version string like '3.0.1' or '3.0' to a (major, minor) tuple so Maltrail's two-component versions can be compared with Cargo's three-component ones. It strips any pre-release/build suffix (after '-' or '+') and then requires at least major.minor. A version with fewer than two dot-separated components cannot be reduced and triggers this exit.

Solutions

  1. Use a version with at least major.minor, e.g. '3.0' or '3.0.1'
  2. Re-run with --tag '3.0' (or 'v3.0') instead of a major-only tag
  3. Check the version source (tag/CITATION.cff/Cargo.toml) for accidental truncation
  4. Remember pre-release suffixes like '3.0.0-rc1' are allowed — the issue is missing the minor component

Example fix

// before
check_version.py --tag 3
// after
check_version.py --tag 3.0
Defensive patterns

Strategy: validation

Validate before calling

import re
def is_valid_series(v):
    v = re.split(r'[-+]', v, 1)[0]
    parts = v.split('.')
    return len(parts) >= 2 and parts[0].isdigit() and parts[1].isdigit()

Prevention

When it happens

Trigger: Passing --tag or configuring a version like '3', 'v3' (after prefix stripping), or an empty-ish value so that after re.split(r'[-+]') and split('.') there are fewer than 2 parts.

Common situations: Tagging a release as just '3' instead of '3.0'; passing a major-only version on the CLI; a version source containing only one numeric component.
