DestroyDB() doesn't remove .ldb files

[GoogleCodeExporter]

New LevelDB directories with .ldb files don't get properly cleaned up by a 
DestroyDB() which still seems to only be looking for .sst files. Everything 
else is properly removed, leaving only .ldb files.

(1.14.0)

Seems to be working for me on linux. On what platform are you seeing it?

You would see this behavior if you created a leveldb instance with 1.14.0 but 
tried to delete it with a previous version. Any chance that's what happened? 
(Sorry, I know nothing about node.js so don't know how possible that could be.)

I'll try and narrow down a small piece of code to reproduce what I'm seeing.

OK, so DestroyDB() works OK except when you run RepairDB before it, so perhaps 
this is a repair problem?

Try this and it'll delete everything but end up with a "lost" directory.

<code language="c++">
#include <leveldb/db.h>
#include <stdio.h>

int main (int argc, char** argv) {
  leveldb::DB* db;
  leveldb::Options options;
  options.create_if_missing = true;
  leveldb::Status status = leveldb::DB::Open(options, "/tmp/testdb", &db);
  char key [10];
  for (int i = 0; i < 200000; i++) {
    sprintf(key, "%d key", i);
    db->Put(leveldb::WriteOptions(), key, "some long string used to fill up more than one sst");
  }
  delete db;

  leveldb::RepairDB("/tmp/testdb", leveldb::Options());

  leveldb::DestroyDB("/tmp/testdb", leveldb::Options());
}
