Hi Dan,
thanks for your reply.
after some code tracking, i found it failed at this point :
in file leveldb/db/db_impl.cc --> NewDB()
log::Writer log(file);
std::string record;
new_db.EncodeTo(&record);
s = log.AddRecord(record);
if (s.ok()) {
fprintf(test, "NewDB: 2\n");
s = file->Close();
}else
fprintf(test, "NewDB: 2.5\n");
the log.AddRecord return s which is not ok().
can you provide some hint why it fails? i am reading the AddRecord()
function now.
Thanks,
Sheng
