mystery config command / help doesn't respond to command abbreviations

[joachim-n]

Describe the bug

I ran into this problem on a new site I'd spun up, where I forgot to enable config_devel module. I was trying to use config_devel to export config to my module:

$ drush @local.fresh cde mymodule
 [error]  Config mymodule does not exist
 $ drush @local.fresh help cde:
  cde command not found.
$ drush @local.fresh cde
 Choose a configuration:
  [0  ] Cancel
  [1  ] automated_cron.settings
  [2  ] block.block.bartik_account_menu
  [3  ] block.block.bartik_branding
  [4  ] block.block.bartik_breadcrumbs
SNIP

So some command is being run, but NOT the one in config_devel (since it's not enabled -- and I checked it's not being run by adding die() to the top of the PHP file: it's not being loaded at all).

But I don't know WHICH command is being run, because the help system won't tell me!

So the problem is this: if 'drush foo' causes a command to run, because it's perhaps
detecting that 'foo' partially matches a command name, then 'drush help foo' should also work.

Expected behavior

Either:

• tell me that command cde doesn't exist and not try to run a command
• tell me what command cde actually is when I ask for help on it

Do you know why drush @local.fresh cde mymodule does not work, but drush @local.fresh cde does?

[joachim-n]

I don't know, as I can't figure out what command cde runs when Config Devel is absent, because help won't tell me. I imagine it's some sort of config-related command. And cde mymodule doesn't work because it's expecting a config name as a parameter, and mymodule isn't one.

[greg-1-anderson]

Oh, helps if I read the [error] line more carefully. The command is running, it is just failing with an error. So the problem is that help is not finding commands that require a bootstrap. That's a bug we should fix.

Workaround:

$ drush @local.fresh cde --help

[joachim-n]

$ drush @local.fresh cde --help

In HelpCommands.php line 58:

  cde command not found.

[joachim-n]

I just tried using --debug, but that doesn't say which command class is being run. Might be a useful addition?

[greg-1-anderson]

Bah, I thought that help used to work with module commands. Looks like it is quite broken now though.

[greg-1-anderson]

Oh, right, it's never worked for disabled modules. Forgot about that.

[joachim-n]

Oh, right, it's never worked for disabled modules

But it's not actually about that.

I get this:

$ drush @local.fresh cde foo
 [error]  Config foo does not exist

even if I delete the whole of the config_devel folder.

Some mystery command is picking up cde.

A PR to add a debug log showing the command class + namespace would be welcome.

A PR to add a debug log showing the command class + namespace would be welcome.

Looks to be non-simple, see issue I've just filed on AC ^^.

[joachim-n]

Ok, getting weirder. For want of debug output, I added a dump() to CommandProcessor::runCommandCallback(), to output which class is about to be run for the command. And it's NOT RUN when I do drush @local.fresh cde foo.

You are running config:delete which has an alias cdel. I suspect you are running into a Symfony Console feature which guesses the command you meant to type. I guess it doesn't do so for remote help. I'm not sure if this is best fixed in Drush or Symfony Console.
