Error when processing files

[geruiz]

Hi,
During the scanner execution, errors of this type appear and cause the scanner to abort. The file have a valid PL/SQL procedure definition, using UTF-8 encoding without BOM.

What is the cause, and how can it be mitigated? Is it possible that it does not cause the scanner to be terminated?

I'm using sonar-plsql-cop-secondary-8.9.6.jar (I also tried with the standalone version with the same result).

[PhilippSalvisberg]

Thank you for reporting this issue. Can you please provide the file so that we can reproduce the issue?

[geruiz]

I was looking for a file to attach and I realised that the error occurs when there are many files to process, because if I process it alone everything works fine. Is there a restriction on the number of files?

Thank you

[PhilippSalvisberg]

Have you configured your license key as shown in https://github.com/Trivadis/plsql-cop-sonar#standalone-plugin ? If not then the limitations of the trial/preview license apply.

However, you should get a proper error message when the license limit is reached.

[geruiz]

Hi, I don't have a licence key because I was evaluating this plugin for a possible purchase.

Does this error not appear when there is a valid licence key?

[PhilippSalvisberg]

The plugin should report a proper error and never crash. So it's a bug. I will look into it.

Here's an update preview/trial license you can use to register in SonarQube:

----- BEGIN LICENSE -----
maxFiles=0
maxLines=5000
maxCommands=200
maxBytes=400000
versionLt=5
validThru=2023-07-01

----- END LICENSE -----
----- BEGIN SIGNATURE -----
MCwCFGEbtLMpSRjxqK/1
+ztx4W25ljvxAhRKt5pa
Qz6eD0yqwocuejGHafLM
CQ==
----- END SIGNATURE -----

If you need a key without size limitations you can contact roland.stirnimann@accenture.com and request one.

Thanks for the trial key, however, I keep getting the same error.

Also, I found this error with a file:

although in this case the result was saved without error.

[PhilippSalvisberg]

Thanks for the trial key, however, I keep getting the same error.

Yes, I could reproduce it. There are cases where the sonar-scanner crashes when a license limit is reached instead of reporting the limit as an error and stopping analyzing subsequent files. What's expected is something like this:

...
INFO: Process resource test_suite_builder.pks
ERROR: license limit reached while analyzing test_suite_builder.pks, skipping other files
INFO: Sensor PlSQL COP Sensor [plsqlcop] (done) | time=4313ms
...

The crash is clearly a bug. We have to fix it.

Until it is fixed you have basically two options:

a) test with e reduced set of files that does not reach the limit
b) request a trial license key that has no limitations (by e-mail, see comment above)

Also, I found this error with a file:

...
org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException: index=0, size=0
...

This is another bug in a validator check. Please provide us the file that causes this issue.

Thank you.

[geruiz]

I am providing you the file that causes the error, as well as the output of its execution.

Thank you.

execution_bug.zip

[PhilippSalvisberg]

@geruiz Thank you for the file. I can reproduce the behaviour. The root cause of the error is a syntax error in your file. There is a missing right parenthesis on line 110:

when you change

                AND OT.OID = NVL(v_OPERATION_TYPE,OT.OID);

to

                AND OT.OID = NVL(v_OPERATION_TYPE,OT.OID));

sonar-scanner completes without error.

Nevertheless, the validator should be able do deal with syntax errors.

[geruiz]

Thanks for your reply. I didn't look for syntax errors. :-(

[PhilippSalvisberg]

The syntax errors are reported. The errors thrown in the validator do not prohibit the processing of the file. You should get a similar result as shown the following screenshots. The error messages are not really good, however, they clearly tell you that db* CODECOP was not able to parse the file successfully.

[PhilippSalvisberg]

fixed with db* CODECOP for SonarQube v8.9.7
