[CBRD-24633] Delete owner information from schema, index, trigger, and object files of general users.

[airnet73]

http://jira.cubrid.org/browse/CBRD-24633

Purpose
If there is owner information in the schema file, an error may occur when moving data from user_a to user_b. In this case, it is necessary to delete the owner information or change the onwer information in the schema file. In order to remove this inconvenience, it is necessary to delete the owner information.

Implementation

• Change File
  Schema file, Index file, Trigger file, Object file

AS_IS

CREATE CLASS [user2].[test_t] REUSE_OID, COLLATE utf8_bin;
ALTER CLASS [user2].[test_t] ADD ATTRIBUTE
[col] integer NOT NULL;

CREATE PRIVATE SYNONYM [user1].[user1_s1] FOR [user2].[test_t];

TO_BE

CREATE CLASS [test_t] REUSE_OID, COLLATE utf8_bin;
ALTER CLASS [test_t] ADD ATTRIBUTE
[col] integer NOT NULL;

CREATE PRIVATE SYNONYM [user1_s1] FOR [user2].[test_t];

• Add option
  --same-as-dba : If the login user is a member of the DBA group, extract the same schema file as the DBA.

Remarks
N/A

Should we ctxt.login_user verify whether NULL or not?
I found ctxt.classes is checked. But ctxt.login_user is not found.

what about:
--as-dba

[kisoo-han]

Even I'm not sure it is effieient but I'll propose a solution to simplify, it up to you its just idea:

1. define a function like:

char *
print_owner_name (char * owner_name, bool print_owner_name)
{
  char buf[DB_MAX_USER_LENGTH+4] = "";

  if (print_owner_name)
    {
      sprintf (buf, "%s%s%s%s", PRINT_IDENTIFIER (owner_name), ".")
    }

  return buf;
}

2. Next re-write following if-else-block as follow:

if (text_print (obj_out, NULL, 0, "%cid %s%s%s%s %d\n", '%', print_owner_name (owner_name, ctxt.is_dba_user || ctxt.is_dba_group_member), PRINT_IDENTIFIER (class_name), ) != NO_ERROR)
  {
    status = 1;
    goto end;
  }
