chore(main): release 6.7.0 [skip-ci]

[github-actions]

🌱 A new release!

6.7.0 (2024-05-01)

The MongoDB Node.js team is pleased to announce version 6.7.0 of the bson package!

Release Notes

Add Long.fromStringStrict method

The Long.fromStringStrict method is almost identical to the Long.fromString method, except it throws a BSONError if any of the following are true:

• input string has invalid characters, for the given radix
• the string contains whitespace
• the value the input parameters represent is too large or too small to be a 64-bit Long

Unlike Long.fromString, this method does not coerce the inputs '+/-Infinity' and 'NaN' to Long.ZERO, in any case.

Examples:

Long.fromStringStrict('1234xxx5'); // throws BSONError
Long.fromString('1234xxx5'); // coerces input and returns new Long(123400)

// when writing in radix 10, 'n' and 'a' are both invalid characters
Long.fromStringStrict('NaN'); // throws BSONError
Long.fromString('NaN'); // coerces input and returns Long.ZERO

Note

Long.fromStringStrict's functionality will be present in Long.fromString in the V7 BSON release.

Add static Double.fromString method

This method attempts to create an Double type from a string, and will throw a BSONError on any string input that is not representable as a IEEE-754 64-bit double.
Notably, this method will also throw on the following string formats:

• Strings in non-decimal and non-exponential formats (binary, hex, or octal digits)
• Strings with characters other than sign, numeric, floating point, or slash characters (Note: 'Infinity', '-Infinity', and 'NaN' input strings are still allowed)
• Strings with leading and/or trailing whitespace
  Strings with leading zeros, however, are also allowed.

Add static Int32.fromString method

This method attempts to create an Int32 type from string, and will throw a BSONError on any string input that is not representable as an Int32.
Notably, this method will also throw on the following string formats:

• Strings in non-decimal formats (exponent notation, binary, hex, or octal digits)
• Strings with non-numeric and non-leading sign characters (ex: '2.0', '24,000')
• Strings with leading and/or trailing whitespace

Strings with leading zeros, however, are allowed

UTF-8 validation now throws a BSONError on overlong encodings in Node.js

Specifically, this affects deserialize when utf8 validation is enabled, which is the default.

An overlong encoding is when the number of bytes in an encoding is inflated by padding the code point with leading 0s (see here for more information).

Long.fromString takes radix into account before coercing '+/-Infinity' and 'NaN' to Long.ZERO

Long.fromString no longer coerces the following cases to Long.ZERO when the provided radix supports all characters in the string:

• '+Infinity', '-Infinity', or 'Infinity' when 35 <= radix <= 36
• 'NaN' when 24 <= radix <= 36

// when writing in radix 27, 'n' and 'a' are valid characters, so 'NaN' represents the decimal number 17060
Long.fromString('NaN', 27); // new Long(17060)
Long.fromString('NaN', 10); // new Long(0) <-- Since 'NaN' is not a valid input in base 10, it gets coerced to Long.ZERO

Features

• NODE-5648: add Long.fromStringStrict() (#675) (9d5a5df)
• NODE-6086: add Double.fromString() method (#671) (e943cdb)
