diagnostics_channel

What steps will reproduce the bug?

import{channel,subscribe}from'node:diagnostics_channel';import{DatabaseSync}from'node:sqlite';constch=channel('sqlite.db.query');constdb=newDatabaseSync(':memory:');console.log('before:',ch.hasSubscribers);try{subscribe('sqlite.db.query',null);}catch(error){console.log('caught:',error.code);}console.log('after:',ch.hasSubscribers);// This query enters the unnecessarily installed native trace callback.db.exec('SELECT 1');db.close();

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

The invalid callback should be rejected before the channel becomes active or native modules are notified, and hasSubscribers should remain false.

What do you see instead?

before: falsecaught: ERR_INVALID_ARG_TYPEafter: true

A rejected subscription changes hasSubscribers from false to true even though no callback was installed.

                Subsystem
                diagnostics_channel
                What steps will reproduce the bug?
                import{channel,subscribe}from'node:diagnostics_channel';import{DatabaseSync}from'node:sqlite';constch=channel('sqlite.db.query');constdb=newDatabaseSync(':memory:');console.log('before:',ch.hasSubscribers);try{subscribe('sqlite.db.query',null);}catch(error){console.log('caught:',error.code);}console.log('after:',ch.hasSubscribers);// This query enters the unnecessarily installed native trace callback.db.exec('SELECT 1');db.close();
                How often does it reproduce? Is there a required condition?
                Always
                What is the expected behavior? Why is that the expected behavior?
                The invalid callback should be rejected before the channel becomes active or native modules are notified, and hasSubscribers should remain false.
                What do you see instead?
                before: falsecaught: ERR_INVALID_ARG_TYPEafter: true
                A rejected subscription changes hasSubscribers from false to true even though no callback was installed.
