Debugging Symfony Controller Using PHPStorm

In order to debug symfony or php apps that uses front end controller approach, you need to have several things:

To debug incoming http request, you need to have a webserver running configuration. We'll use the PHP Built-in Web Server as it's sufficient for our purpose. Click Run > Edit Configurations > Add New Configuration > PHP Built-in We

SQLite 3 Notes

Some notes when working with SQLite 3

SQLite 3 Compile Time Options And Pragma

SQLite has multiple build flag and pragmas that can be used to enable / disable certain functionality. Due to this, it's important to remember if certain functionality exist on your target servers

Why?

Minimal PHP system needed to run CRUD symfony app
Better understanding of PHP configurations
Newer sqlite support, like window functions and JSON1 extension

Better use zswap, as it will work in conjunction with swap devices https://www.addictivetips.com/ubuntu-linux-tips/enable-zswap-on-linux/

In /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash zswap.enabled=1 zswap.compressor=lz4 zswap.max_pool_percent=40 zswap.zpool=z3fold"

run sudo update-grub

In /etc/default/grub, modify:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off tsx=on tsx_async_abort=off mitigations=off"

Then sudo update-grub

Homebrew install

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Libraries

brew install rbenv ruby-build sqlite3 jemalloc gmp

sudo apt install zram-config, this will install several files, including systemd startup /etc/systemd/system/multi-user.target.wants/zram-config.service
sudo nano /usr/bin/init-zram-swapping and edit:

#!/bin/sh

# load dependency modules
NRDEVICES=1
if modinfo zram | grep -q ' zram_num_devices:' 2>/dev/null; then
 MODPROBE_ARGS="zram_num_devices=${NRDEVICES}"
