Drush fatal error with various commands -- looking for Drupal 8 RfcLogLevel

[jenlampton]

I'm seeing the following while attempting drush updb -y

Fatal error: Uncaught Error: Class 'Drupal\Core\Logger\RfcLogLevel' not found in drush-8/commands/core/drupal/environment.inc:334

[serundeputy]

@jenlampton do you have devel enabled with the show deprecated opiton checked as in #173 (comment) or is updb just always failing for you?

I have not had time to try to replicate myself yet.

I just tried on a vanilla Backdrop 1.x and drush updb -y ran successfully. Also worth noting that drush updb -y is passing tests in CI.

I just enabled devel w/ the deprecated option and drush updb -y still worked all be it with no updates available.

So we still need STR to get moving on this issue.

When I get this error, it's running drush_watchdog_severity_levels() from the Drush phar code, not the version that is in .drush/commands/backdrop/. This is Drush 8.1.15.

update: ah, no, it's earlier. Drush 8 implements system_watchdog(), which gets called by any watchdog() error, and it is apparently not playing well with Backdrop.

[jenlampton]

@serundeputy I found that I was still on the ongoing-saga-of-en branch for my checkout of Drush. When I switched to the 1.x-1.x branch updates work again :)

@bradbulger check your drush branch, are you on 1.x-1.x?

(going to close this issue -- @bradbulger please re-open if needed!)

Weirdly I'm seeing the same error under different circumstances, with just one site in just one environment:

drush cc all   
Error: Class 'Drupal\Core\Logger\RfcLogLevel' not found in drush_watchdog_severity_levels() (line 334 of /opt/drush/8/drush/drush/commands/core/drupal/environment.inc).
Drush command terminated abnormally due to an unrecoverable error. 

In the environment where this happens I'm running Backdrop 1.13.2, Drush 8.2.3, and the latest commit in branch 1.x-1.x of the Backdrop Drush commands; it occurs whether I use PHP 7.2 or PHP 7.3.

The identical site (same exact codebase) in a different environment using PHP 7.3 does not experience this error using the same versions of Drush and the Drush Backdrop commands. And other Backdrop sites in the same environment as the one with the problem do not experience the same error.

For the life of me I can't figure out what's going on here!

[jackaponte]

Now I see I get the same error on a different site in the same environment. On this site drush cc all works fine but this doesn't:

drush dis devel
The following projects will be disabled: devel.
    Do you want to disable the projects? (y/n): y
Error: Class 'Drupal\Core\Logger\RfcLogLevel' not found in drush_watchdog_severity_levels() (line 334 of /opt/drush/8/drush/drush/commands/core/drupal/environment.inc).
Drush command terminated abnormally due to an unrecoverable error.  

But then look what happens when I immediately run this series of commands after that:

drush dis devel_generate
The following projects will be disabled: devel_generate.
    Do you want to disable the projects? (y/n): y

	Success: devel_generate are disabled.

drush dis devel
The following projects will be disabled: devel.
    Do you want to disable the projects? (y/n): y

	Success: devel are disabled.

drush en devel_generate
The following projects will be enabled: devel, devel_generate.
    Do you want to enable the projects? (y/n): y

	Success: module devel enabled.


	Success: module devel_generate enabled.

drush dis devel
The following projects will be disabled: devel_generate,devel.
    Do you want to disable the projects? (y/n): y

	Success: devel_generate,devel are disabled.

So...in some cases this problem comes and goes, but when it does happen, it's a fatal error?

[jenlampton]

@jackaponte check the drush branch, or if you have any patches applied. Maybe delete / replace drush where you are seeing the error, just to be sure?

@jackaponte check the drush branch, or if you have any patches applied. Maybe delete / replace drush where you are seeing the error, just to be sure?

I'm using Drush 8.2.3 with no patches applied; I'm on the 1.x-1.x branch of the Backdrop commands, with commit ec2fa84d6 as the most recent commit and no difference from https://github.com/backdrop-contrib/drush.git according to git diff origin/1.x-1.x.

But as I noted before, the problem comes and goes, fairly inscrutably. When I started writing this update, drush cc all was working fine on one of the sites in my local environment, and now a few drush cc drushes later it's not working again. :(

[bradbulger]

I am not running drush from checked out code. I'm not entirely sure how to do that. This is my global Drush installation in /usr/local/bin/drush that's running a drush.phar file. The version is 8.1.15. (The "drush version" command does not work in a Backdrop context btw.)

It is loading system_watchdog() from phar:///usr/local/bin/drush.phar/includes/drupal.inc and that causes the attempt to run Drupal 8 code (or whatever the reference to RfcLogLevel is). If it only does this sometimes, then the question is, when does it include that file?

[jackaponte]

@bradbulger Have you tried installing a fresh copy of the Drush Backdrop commands and seeing whether the issue persists for you? You can download the most recent 1.x-1.x release via this link: https://github.com/backdrop-contrib/drush/archive/1.x-1.x.zip

[jackaponte]

Error: Class 'Drupal\Core\Logger\RfcLogLevel' not found persists for me on this one Backdrop 1.13.2 site, using Drush 8.2.3, Backdrop Drush 1.x-1.x and PHP 7.2.

Some observations in case they jog anyone's memory:

backdrop_pm_enable.drush.inc is the only Backdrop Drush file I can find that includes use Drupal\Core\Logger\RfcLogLevel; up at the very top; should that be there?

The error refers to line 334 of /opt/drush/8/drush/drush/commands/core/drupal/environment.inc. The code in reference:

/**
 * Helper function to obtain the severity levels based on Drupal version.
 *
 * @return array
 *   Watchdog severity levels keyed by RFC 3164 severities.
 */
function drush_watchdog_severity_levels() {
  return array(
    RfcLogLevel::EMERGENCY => LogLevel::EMERGENCY,
    RfcLogLevel::ALERT => LogLevel::ALERT,
...

That function is replaced in backdrop/includes/environment.inc. But maybe, on some sites, something is causing Drush to not properly detect that Backdrop is being used, causing the Drupal version of the function to be used instead?

[jackaponte]

Welp, not long later I tried disabling then re-enabling civicrm and its dependent modules on the site where this was giving me trouble, and magically the error has gone away when running drush cc all (though I did get the error one last time when using drush to disable the modules.) I can't explain why. I'll update this if the error recurs anywhere!

[bugfolder]

FWIW, I just encountered this same error, and disabling civicrm made it go away. (Though re-enabling civicrm brought it back.)

[laryn]

Strange, I am using drush on a number of sites that run civicrm and am not seeing this. Which command in particular causes the error, @bugfolder?

[bugfolder]

It was drush dis, also drush pmu.

[klonos]

I confirm both drush dis and drush pmu having this issue:

drush dis node_clone -y

I'm testing PHP 8 with backdrop-drush. I get this error in PHP 8 but not in PHP 7.4 (when running drush status). It happens all over the place because it's trying to actually log some other error and then encounters this fatal error.

Things have likely moved around a bit so the error is in environment_common.inc now:

PHP Fatal error: Uncaught Error: Class "Drupal\Core\Logger\RfcLogLevel" not found in phar:///usr/local/bin/drush/commands/core/drupal/environment_common.inc:294
