Undefined constant "SIGTERM" in ConsumeMessagesCommand.php line 261 #51893
Description
Symfony version(s) affected
6.3.5
Description
Due to someone's recent changes, symfony/messenger now has an implicit dependency on ext-pcntl, which my app does not have, so simply running messenger:consume now throws this exception.
In ConsumeMessagesCommand.php line 261:
[Error]
Undefined constant "SIGTERM"

How to reproduce
Assuming you do not have pcntl installed (php -m):
bin/console messenger:consume
Possible Solution
Pick one:
a. Hard-code the constant values
b. Redeclare the constants in a local namespace.
c. Explicitly specify ext-pcntl as a dependency in composer.json.
