Added files:
csup idcache.c idcache.h
Log:
Add an implementation of a thread-safe cache for lookups in the group
or password files, per name or per uid/gid. It serves two purposes.
First, it makes the code thread-safe by serializing calls to getpwuid()
or getpwnam() and calls to getgrgid() or getgrnam(). Second, it's a
cache so we avoid calling those functions several times for the same
password/group file entry. It's implemented using four separate hash
tables (uid->name, gid->name, name->uid, name->gid).
