|
|
|
|
|
identifiers to an arbitrary length (set by MAX_LABEL_LENGTH).
|
|
|
|
|
|
|
|
|
|
It attempts to make each truncated identifier unique by replacing
|
|
|
|
|
part of the identifier with an encoded 32-bit CRC and an associated
|
|
|
|
|
checksum (the checksum is used as a way to determine that the name
|
|
|
|
|
was truncated).
|
|
|
|
|
|
|
|
|
|
Note that both a portion of the start and of the end of the
|
|
|
|
|
identifier may be kept. The macro ID_SUFFIX_LENGTH will return the
|
|
|
|
|
number of characters in the suffix of the identifier that should be
|
|
|
|
|
kept.
|
|
|
|
|
|
|
|
|
|
The portion of the identifier that is going to be removed is
|
|
|
|
|
checksummed. The checksum is then encoded as a 5-character string,
|
|
|
|
|
the characters of which are then summed. This sum is then encoded
|
|
|
|
|
as a 3-character string. Finally, the original length of the
|
|
|
|
|
identifier is encoded as a 3-character string.
|
|
|
|
|
|
|
|
|
|
These three strings are then concatenated together (along with an _h
|
|
|
|
|
which further designates that the name was truncated):
|
|
|
|
|
|
|
|
|
|
"original_identifier"_haaaaabbbccc
|
|
|
|
|
|
|
|
|
|
aaaaa = 32-bit CRC
|
|
|
|
|
bbb = length of original identifier
|
|
|
|
|
ccc = sum of 32-bit CRC characters
|
|
|
|
|
|
|
|
|
|
The resulting identifier will be MAX_LABEL_LENGTH characters long.
