hi, all,
in function dbt_db_del_table() of module dbtext, should we do
"lock_release(&_tbc->sem)" before "break" when
we found the cached table for delete? in tbl_cache_free(),
"lock_get(&_tbc->sem)" would be called, deadlock then.
int dbt_db_del_table(dbt_cache_p _dc, str *_s)
{
...
while(_tbc)
{
...
lock_get(&_tbc->sem);
if(_tbc->dtp->name.len == _s->len
&& !strncasecmp(_tbc->dtp->name.s, _s->s,
_s->len))
{
...
//============> need 'lock_release(&_tbc->sem)'
before break ?
break;
}
lock_release(&_tbc->sem);
...
}
...
tbl_cache_free(_tbc);
...
}
regards,
yan lin
