ORA-20000: ORU-10027: buffer overflow, limit of 1000000 bytes #93

wolframhaussig · 2020-03-12T12:53:24Z

Describe the bug
I started yesterday with writing unittests using utPLSQL. Yesterday, everything worked fine but starting this afternoon I cannot use the sqldeveloper plugin to create coverage reports anymore(test run still works).

Executing the script results in:

EXECUTE dbms_session.reset_package;
SET SERVEROUTPUT ON SIZE UNLIMITED
CLEAR SCREEN
EXEC ut.run('[redacted]',ut_coverage_html_reporter())

Fehler beim Start in Zeile: 4 in Befehl -
BEGIN ut.run('[redacted]',ut_coverage_html_reporter()); END;

Expected behavior
I would expect that this call works and creates the coverage report.

This is a SQL Developer and SQLcli issue.

You can run the following successfully in SQL*Plus 19.5:

set serveroutput on size unlimited
begin
   for i in 1..500000 loop
      dbms_output.put_line(i || ': some text');
   end loop;
end;
/

The result ends with:

...
499997: some text
499998: some text
499999: some text
500000: some text

PL/SQL procedure successfully completed.

SQL>

If you run the same script in SQLcl 19.4 or SQL Developer 19.4 you get the following result:

...
63191: some text
63192: some text
63193: some text
63194: some text


Error starting at line : 1 in command -
begin
   for i in 1..500000 loop
      dbms_output.put_line(i || ': some text');
   end loop;
end;

It looks like SQLcl and SQL Developer limit the DBMS_OUTPUT to 1000000 even if you set UNLIMITED.

@thatjeffsmith do you know about this restriction?

jgebal · 2020-03-12T14:41:05Z

One way to fix this in the plugin would ne to use select * from table (ut.run...) function call instead of iding procedire call.
That way you spool output of select instead of spooling dbms_output results.

PhilippSalvisberg · 2020-03-12T14:52:28Z

@jgebal actually, utPLSQL for SQL Developer uses sys.dbms_output.enable(NULL); behind the scenes. This is equivalent to UNLIMITED. So the following should work as well as a workaround:

EXECUTE dbms_session.reset_package;
SET SERVEROUTPUT ON SIZE UNLIMITED
EXECUTE sys.dbms_output.enable(NULL);
CLEAR SCREEN
EXEC ut.run('[redacted]',ut_coverage_html_reporter())

jgebal · 2020-03-12T23:34:44Z

Ah. I thought it's issue with utPLSQL plugin, not with running from Worksheet.

@wolframhaussig
I assume you're all sorted with this issue as per solution provided by @PhilippSalvisberg

Closing.

wolframhaussig · 2020-03-13T05:44:26Z

Hello, @jgebal , I tried @PhilippSalvisberg s proposal and it did not fix it - I still get the same error in the worksheet And you were right: I get the error both in the worksheet and from the plugin - maybe I should have made it more clear. The second error I added in the initial post is from the sqldeveloper plugin.

wolframhaussig · 2020-03-13T06:04:59Z

@jgebal I cannot reopen the issue, would you be so kind to do it?

PhilippSalvisberg · 2020-03-13T09:08:14Z

I checked on my 12.1.0.2.190716OJVMPSU instance. I ran the following script in SQL*Plus, SQLcl and SQL Developer worksheet successfully:

set serveroutput on size unlimited 
execute sys.dbms_output.enable(null);
begin
   for i in 1..500000 loop
      dbms_output.put_line(i || ': some text');
   end loop;
end;
/

@wolframhaussig can you run this in your environment?

jgebal · 2020-03-13T09:26:38Z

I'm transferring this issue to utPLSQL-SQLDeveloper, as it's related to HTML coverage report generation using utPLSQL plugin in SQLDeveloper .

PhilippSalvisberg · 2020-03-13T10:07:17Z

Producing the code coverage report via DBMS_OUTPUT is a bad idea anyway. There is no way to suppress unwanted dbms_output produced by the test run itself. Hence I'm going to change the call as @jgebal has suggested to something like select ... from table(ut.run...). This should solve this issue.
