This patch allows empty scalars as values for mappings or sequences in
shard.yml
.So this is considered a valid specification:
Previously, this caused a YAML parser error:
Expected MAPPING_START but was SCALAR at line 3, column 15
There's no change to internal behaviour because empty mappings and sequences were already allowed (
dependencies: {}
).So this is just a simple UX feature that avoids errors when for example all dependencies are removed but the
dependencies:
key isn't.Both empty string and YAML null value (
~
) are accepted.
