[DrupalCampSpain2022] Introducción al desarrollo de módulos en Drupal 9 keopx Sáb, 04/06/2022 - 18:30

Taller realizado en la DrupalCamp Spain de 2022 centrado en el desarrollo para Drupal 9. En el taller se mostrara la creación de un modulo básico, veremos ejemplos existentes y como poder aprovecharlos para hacer nuestros desarrollos a medida.

Se explicara por encima algunos conceptos.

Puedes facilitar lo que deseas encontrarte en el taller, de esta manera intentare ajustarme a lo que los asistentes desearían conocer :)

Formulario: formulario

Sera necesario tener instalado el entorno de desarrollo, un entorno con Drupal en Docker (Lando, Ddev, Docker4Drupal), LAMP, MAMP, WAMP o similar para poder trabajar.

Se proporciona una OVA (VirtualBox 6.1) para facilitar el desarrollo.

Recomendación:

Drupal 9. Instalado y funcionando.
IDE de desarrollo. En la maquina virtual estara disponible Code.
Se recomienda usar la maquina virtual para facilitar la sesión.

Algunos módulos que veremos, por ello es aconsejable instalarlos.

Modulo Devel
Modulo Coder
Módulo Examples

Están disponibles maquinas virtuales o instaladores para facilitar:

Docker (+ Lando) / Maquina virtual (VitualBox 6.1)

Exploring .img Files on Linux and create your custom one

keopx — Thu, 26 Dec 2019 10:50:37 +0000

Exploring .img Files on Linux and create your custom one

Discover the hidden secrets of a monolithic .img file
Mount the partitions in an .img file using losetup, kpartx and mount
Create your own .img files and use them as virtual disks
Write out your virtual disk image to a thumb drive (or any drive for that matter) for use later

Install packages

$ sudo aptitude install kpartx xz-utils

Decompress image

Once its downloaded you will want to uncompress it with xz --decompress:

$ xz --decompress Retrobro128KillerHomeConsole.img.img.xz

Mount image

We’re going to attach the image file to what is known as a loopback device.

$ sudo losetup /dev/loop0 Retrobro128KillerHomeConsole.img

Note: We used /dev/loop0 in this example. If /dev/loop0 wasn’t available to us (that is, it was already in use), we could have chosen /dev/loop1, etc.

$ sudo losetup -a /dev/loop0: [65026]:28970069 (/home/keopx/Retrobro128KillerHomeConsole.img)

Now /dev/loop0 is attached. How about look at the partition table with fdisk?

$ sudo fdisk -l /dev/loop0 Disco /dev/loop0: 119,8 GiB, 128579534848 bytes, 251131904 sectores Unidades: sectores de 1 * 512 = 512 bytes Tamaño de sector (lógico/físico): 512 bytes / 512 bytes Tamaño de E/S (mínimo/óptimo): 512 bytes / 512 bytes Tipo de etiqueta de disco: dos Identificador del disco: 0xf2d3cb4f Disposit. Inicio Comienzo Final Sectores Tamaño Id Tipo /dev/loop0p1 * 8192 124927 116736 57M e W95 FAT16 (LBA) /dev/loop0p2 124928 251131903 251006976 119,7G 83 Linux

To see what kpartx would map, run it with the -l option:

$ sudo kpartx -l /dev/loop0 loop0p1 : 0 116736 /dev/loop0 8192 loop0p2 : 0 251006976 /dev/loop0 124928

Let’s go ahead and run it and add the maps:

$ sudo kpartx -a /dev/loop0

Now you can see new devices on dolphin.

Running a shell:

Now that the partitions are mapped, let’s examine the filesystems on each partition with file and the --special-files and --dereference options.

$ sudo file -sL /dev/mapper/loop0p1 /dev/mapper/loop0p1: DOS/MBR boot sector, code offset 0x3c+2, OEM-ID "mkfs.fat", sectors/cluster 4, reserved sectors 4, root entries 512, Media descriptor 0xf8, sectors/FAT 116, sectors/track 32, heads 64, sectors 116736 (volumes > 32 MB), serial number 0xb13de1e5, label: "boot ", FAT (16 bit)

$ sudo file -sL /dev/mapper/loop0p2 /dev/mapper/loop0p2: Linux rev 1.0 ext4 filesystem data, UUID=c50e928e-5669-44d0-8e3c-a59d21ad3da2, volume name "retropie" (extents) (64bit) (large files)

Now that we have our partitions mapped, we can mount them. Create two directories to serve as mountpoints:

$ mkdir boot # We will mount the FAT partition here $ mkdir retropie # We will mount the ext4 partition here

Once they are created, mount the filesystems (only system in my case).

$ sudo mount /dev/mapper/loop0p2 retropie

Umount image

Once you are done and want to “let go” of the .img file, reverse the process with:

$ sudo umount retropie $ sudo kpartx -d /dev/loop0 $ sudo losetup -d /dev/loop0

Instalación y configuracion de java

keopx — Mon, 29 Jul 2019 09:23:23 +0000

Instalación y configuracion de java

Obtenemos java

Antes de descargar una versión de java debemos saber la versión del S.O. esto es, si es x86 o amd64. Para ello ejecutamos lo siguiente:

# uname -a
Linux Hetz01 3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:18:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Ahora descargamos java a nuestro equipo:

Instalar JRE

Subimos JAVA

$ scp jre-7u17-linux-x64.tar.gz root@78.47.194.156:.

Ahora instalamos en el servidor

# tar -xvf jre-7u17-linux-x64.tar.gz
# mkdir /usr/lib/jvm
# mv jre1.7.0_17 /usr/lib/jvm/
# update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.7.0_17/bin/java 0
# update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jre1.7.0_17/bin/javaws 0

Instalar JDK

Subimos JAVA

$ scp jdk-7u17-linux-x64.tar.gz root@78.47.194.156:.

Ahora instalamos en el servidor

# tar -xvf jdk-7u17-linux-x64.tar.gz
# mkdir /usr/lib/jvm
# mv jdk1.7.0_17 /usr/lib/jvm/
# update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_17/bin/java 1
# update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/>>jdk1.7.0_17/bin/javac 1
# update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.7.0_17/bin/javaws 1

`Enlaces simbólicos`

Para poder actualiza tanto el jdk como el jre podemos usar el enlace simbólico que apunte concreta de la jvm a uno genérico.

JRE simbólico

# ln -s /usr/lib/jvm/jre1.7.0_17 /usr/lib/jvm/jre1.7.0

Ahora configuramos el nuevo entorno:

># update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.7.0/bin/java 0
># update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jre1.7.0/bin/javaws 0

JDK simbólico

# ln -s /usr/lib/jvm/jdk1.7.0_17 /usr/lib/jvm/jdk1.7.0

Ahora configuramos el nuevo entorno:>

# update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0/bin/java 1
# update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0/bin/javac 1
# update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.7.0/bin/javaws 1

Reconfigurar java

# update-alternatives --config java
# update-alternatives --config javac
# update-alternatives --config javaws

Crear claves GPG2 en GNU/Linux con Ed25519

keopx — Sun, 13 Jan 2019 10:19:23 +0000

Crear claves GPG2 en GNU/Linux con Ed25519

Vamos a crear un par de claves GPG2 basados en cifrado Ed25519. Lo realizaremos en la consola aunque también se puede realizar utilizando "Contraseñas y claves de cifrado".

A continuación, invocamos gpg en la consola con la opción --expert y --full-gen-key.

$ gpg2 --expert --full-gen-key
gpg (GnuPG) 2.1.8; Copyright (C) 2015 Free Software Foundation, Inc. This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law.

Luego, seleccionamos el 9 para seleccionar la clave principal de ECC y la subclave de cifrado de ECC.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
   (7) DSA (set your own capabilities)
   (8) RSA (set your own capabilities)
   (9) ECC and ECC
  (10) ECC (sign only)
  (11) ECC (set your own capabilities)
Your selection? 9

La siguiente es la selección importante. Seleccionamos 1 para seleccionar "Curve25519".

Please select which elliptic curve you want:
   (1) Curve 25519
   (2) NIST P-256
   (3) NIST P-384
   (4) NIST P-521
   (5) Brainpool P-256
   (6) Brainpool P-384
   (7) Brainpool P-512
   (8) secp256k1
Your selection? 1

Verás una ADVERTENCIA, pero es lo que quieres.

gpg: WARNING: Curve25519 is not yet part of the OpenPGP standard.
Use this curve anyway? (y/N) y

Se le pregunta sobre la caducidad de la clave.

Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y

Luego, pregunta sobre una identidad de usuario.



GnuPG needs to construct a user ID to identify your key.

Real name: keopx
Email address: keopx@keopx.net
Comment:
You selected this USER-ID:
    "keopx <keopx@keopx.net>"

Por último, pide confirmación.

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o

Entonces, va así.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
