Cli: sfdx force:apex:execute does not exit after completion when using inline apex or piping in from command line

[btamburrino]

Summary

We have a script that runs multiple generated Apex lines and pipes them through sfdx force:apex:execute. This has, historically, worked beautifully, however today when I revisited those scripts, they no longer exit out of sfdx after completing successfully, which blocks the rest of our script execution.

Steps To Reproduce:

Two ways:

• echo "System.debug('Hello');" | sfdx force:apex:execute

OR

• Run sfdx force:apex:execute, type a line and hit CTRL-D to trigger execution

Expected result

Anonymous code executes (or returns an error) and then exits back to the command line

Actual result

Anonymous code executes (or returns an error) and hangs, requiring the user to hit CTRL-C to Terminate batch job (Y/N)? - which then terminates the calling shell script that had been blocked.

EDIT Part of this is impatience. It DOES finally exit out after about a minute, however before it was virtually instantaneous.

$ echo "System.debug('Hello');" | sfdx force:apex:execute
Start typing Apex code. Press the Enter key after each line, then press CTRL+D when finished.
System.debug('Hello');
Compiled successfully.
Executed successfully.

One of my colleagues on Mac verified that this bug occurs for them as well with the latest sfdx, so it is sadly not a Windows-only issue.

[btamburrino]

The root cause is because of the new timeout in module @salesforce/apex-node executeService.js. In getUserInput() there is a timeout of 60 seconds on the readInterface. This timeout is not closed when the readInterface sends a close event, so the awaiter is waiting for the timeout to complete.

If you add timeout.close(); after resole(apexCode); then the bug reported here goes away. This timeout did not exist in the original implementation that was in salesforce-alm hence why it was not an issue before

// apex-node/../executeService.js getUserInput()
readInterface.on('close', () => {
   resolve(apexCode);
   timeout.close();  // add me!
});

A workaround is to write to an intermediate file:

echo "System.debug('Hello');" > throwaway.apex
sfdx force:apex:execute -f throwaway.apex
