I assume this is a bug that might happen if you have multiple install attempts and the mysql.user is still there. I had the same problem today.
I have filed the bug as:
https://phabricator.wikimedia.org/T177768
the Problem went away after reinstalling with the following steps:
dropping database
removing user from mysql.users
strangely the "user exists" error still appeared on installation
granting access rights was therefore necessary on the mysql database.

Perch CMS isn't connecting to my XAMPP database

I'm just trying to install Perch CMS into my site locally. At setup, I put in my XAMPP database server host name, username and I leave the password blank because that is how it is meant to be. But it shows me this error code when I try to move forward:
Fatal error: Uncaught Error: Undefined constant "PERCH_DB_PASSWORD" in C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php:46 Stack trace: #0 C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php(46): constant('PERCH_DB_PASSWO...') #1 C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php(75): PerchDB_MySQL->config('PERCH_DB_PASSWO...') #2 C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php(117): PerchDB_MySQL->open_link() #3 C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php(460): PerchDB_MySQL->get_link() #4 C:\xampp\htdocs\dschc\cms\setup\PerchSetup_Installation.class.php(13): PerchDB_MySQL->test_connection() #5 C:\xampp\htdocs\dschc\cms\setup\database\index.php(50): PerchSetup_Installation->test_db(Array) #6 {main} thrown in C:\xampp\htdocs\dschc\cms\core\lib\PerchDB_MySQL.class.php on line 46
P.S I have never changed my database connection credentials since I installed XAMPP

Typo3 Cache Flush Exception - How to debug

I have a dockerized TYPO3 instance on a server and try to flush the typo3 cache manually.
So, I use the following command to do that, inside my docker container:
vendor/.bin/typo3cms cache:flush
However, it fails and returns this error:
[ TYPO3\CMS\Core\Error\Exception ]
Warning: rename(): The first argument to copy() function cannot be a directory in /home/app/vendor/typo3/cms/typo3/sysext/core/Classes/Utility/GeneralUtility.php line 2432
How I can debug this and find out what the problem is?

This was a known issue and fixed with version 5.8.6 of the TYPO3 Console.
Well, the question was: How to debug this. Even if the problem is now solved, this may help:
You got the exception trace. You set a breakpoint in GeneralUtility.php line 2432.
If you already have xdebug set up, you only need to start the command line command with appropriate options, e.g with -e for generating debug information.
You can also look at DDEV. The last time I tried it, it worked pretty nicely to get the debugger to run, see https://ddev.readthedocs.io/en/stable/users/step-debugging/
I usually use xdebug in combination with PhpStorm.

ZF version is 1.11.6, MySQL server version is 5.5.37, running on ubuntu 12.04 with php 5.3.10.
It's a legacy application, so that's the reason of having a so old version of Zend Framework.
Any help on that?
Thanks
