Roy Lenferink created CELIX-391:
-----------------------------------
Summary: The utils_stringHash does not generate unique hashes.
Key: CELIX-391
URL: https://issues.apache.org/jira/browse/CELIX-391
Project: Celix
Issue Type: Bug
Reporter: Roy Lenferink
Priority: Minor
Attachments: utils_stringHash bug.png
The utils_stringHash function is generating the same id for a set of different
strings.
The following code can be used (the DJB2 Hash algorithm):
--------------------------------------------
unsigned int hc = 5381;
char ch;
while((ch = *string++) != '\0') {
hc = (hc << 5) + hc + ch;
}
return hc;
---------------------------------------------
