Identifiers

Rule code BSL028
Compatible alias MissingCodeTryCatchEx
Severity INFORMATION
Enabled by default Yes
Implemented Yes
Tags error-handling, robustness

Behavior

  • The public identifier BSL028 and alias MissingCodeTryCatchEx are stable.
  • The rule reports the cases documented on this page.
  • Suppressions and project configuration are applied before publication.
  • The rule requires neither an external analyzer nor network access.

Configuration and suppression

BSL### is the primary stable identifier. The compatible alias is accepted in select, ignore, and compatible block suppression comments.

[tool.onec-hbk-bsl]
select = ["BSL028"]
ignore = ["MissingCodeTryCatchEx"]

All three suppression families support both a current line and a range. When an opening comment follows code, it affects only that line. Use any one form:

  • noqa:
Value = "example";  // noqa: BSL028
  • bsl-disable:
Value = "example";  // bsl-disable: BSL028
  • compatible BSLLS form:
Value = "example";  // BSLLS:MissingCodeTryCatchEx-off

When the same opening comment is on a line by itself, it starts a range. Close it with the matching marker from the same family:

// noqa: BSL028
// code without this diagnostic
// noqa-enable: BSL028

// bsl-disable: BSL028
// code without this diagnostic
// bsl-enable: BSL028

// BSLLS:MissingCodeTryCatchEx-off
// code without this diagnostic
// BSLLS:MissingCodeTryCatchEx-on

To disable the rule until the end of the file, omit the closing noqa-enable, bsl-enable, or BSLLS:…-on marker.

Opening and closing markers must belong to the same family.

Description

It is unacceptable to catch any exception, without any trace for system administrator.

Incorrect

Try
    // code causing exception
    ....
Raise // catch any exception
EndTry;

As a rule, such a design hides a real problem, which is subsequently impossible to diagnose.

Correct

Try
    // code causing exception
    ....
Raise
    // Explanation why catching all exceptions untraceable for enduser.
    // ....
    // Write to log for system administrator.
    WriteLogEvent(NStr("en = 'Action'"),
       EventLogLevel.Error,,,
       DetailErrorDescription(ErrorInfo()));
EndTry;
