Firebird 3.0 Beta 1 release is available for testing

Firebird Project announces the first Beta release of Firebird 3.0, the next major version of the Firebird relational database, which is now available for testing.

This Beta release demonstrates the features and improvements currently under development by the Firebird development team. Our users are appreciated giving it a try and providing feedback to the development mailing list. Apparent bugs can be reported directly to the bugtracker.

Beta releases are not encouraged for production usage or any other goals that require a stable system. They are, however, recommended for those users who want to help in identifying issues and bottlenecks thus allowing to progress faster through the Beta/RC stages towards the final release.

Please read the Release Notes carefully before installing and testing this Beta release.

Node.JS and Firebird driver (node-firebird-libfbclient) installing on Amazon EC2 instance

Here are the notes on Installing node.js module for firebird
I assume Firebird was installed from source or from tar.gz and in a linux instance

wget https://nodejs.org/dist/v4.6.0/node-v4.6.0.tar.gz
tar -zxvf node-v4.6.0.tar.gz
cd  node-v4.6.*
./configure 
sudo make install

Next is time to install the firebird module (Firebird was installed from source in /opt/firebird2.5.x)

git clone git://github.com/xdenser/node-firebird-libfbclient.git
cd node-firebird-lib
export PATH=$PATH:/opt/firebird2.5.x/binfbclient/

npm -g install

create firebird db and test table in /tmp/nodedb.fdb with isql or isql-fb

SQL>CREATE DATABASE "localhost:/tmp/nodedb.fdb" user 'SYSDBA' password '*********';
SQL> CREATE TABLE TEST (ID INT NOT NULL PRIMARY KEY, NAME VARCHAR(20));
SQL> create generator gen_test_id;
SQL> SET GENERATOR gen_test_id TO 10;
SQL> set term !! ;
SQL> CREATE TRIGGER TEST_BI FOR TEST
CON> ACTIVE BEFORE INSERT POSITION 0
CON> AS
CON> BEGIN
CON> if (NEW.ID is NULL) then NEW.ID = GEN_ID(GEN_TEST_ID, 1);
CON> END!!
SQL> set term ; !!

Then write the test.js script to connect to it



you can observe that the id is auto incremented if you run it multiple time

node test.js 
[ { ID: 5, NAME: 'new one' },
  { ID: 11, NAME: 'new one' },
  { ID: 12, NAME: 'new one' },
  { ID: 13, NAME: 'new one' },
  { ID: 14, NAME: 'new one' } ]

also in the name you can put later the
browser or the ip in one of the columns


We build now the version for the web modifying the hello world version adding the firebird database glue



you can run it with

 node firebird_example.js

Rails On Firebird - status and follow the guide

Rails On Firebird - you need to check that Firebird active record adapter and ruby driver are installed
Install Rails 4.x :

 gem install rails

Generate a new Firebird Rails application

rails new firebird_app 

delete the generated database.yml sqlite config and use the one from bellow
Be aware about indentation
cat config/database.yml

Edit the project Gemfile and add the activerecord-fb-adapter gem:

gem 'activerecord-fb-adapter'

Then run:

bundle update

 rails generate scaffold Client name:string address:string email:string remark:text

  rake db:migrate

I have re-read the ruby guide
so i did these commands while following the official guide

rake db:create

but database was already created in flamerobin

script/generate controller home index
vi app/views/home/index.html.erb

and write something there, start the server with

rails s

and now you can see something in browser
http://localhost:3000/


I have created the table and one sequence in firebird db

CREATE TABLE posts (
id BIGINT NOT NULL PRIMARY KEY,
name VARCHAR(255),
title VARCHAR(255),
content VARCHAR(255),
timestamps timestamp
);
CREATE sequence POSTS_SEQ;

I have ran the scaffold again to generate the posts model/view/controller

script/generate scaffold Post name:string title:string content:text

and then
started the server

rails s

Of course I have modified the route and added an link as in tutorial and now i can add and modify blog posts
note: in new rails route is defined this way in config/routes.rb

map.root :controller => "home"

http://localhost:3000/posts






Follow the normal ActiveRecord conventions for table names, primary key columns, etc. The one “extra” you’ll need for Firebird is that you’ll have to create a generator for any tables that require a sequence-based primary key. The default naming convention is TABLENAME_SEQ. So if you have a users table, you would need to create a corresponding USERS_SEQ generator

You don't need to create before insert triggers ! rails reads the value from sequence and then increments it in ruby code, Yay!

Installing Android x86 4.4 on my eeepc with qemu

In fact is an re-install , i had 4.3 in dual boot with debian sid on my eeepc and i wanted to do an upgrade , the issue is that i don't have a usb stick to boot from it so i took another route

I have installed qemu and then downloaded the 4.4 iso from android x86 site and started this way to detect partitions on the main drive

qemu -boot d -cdrom android-x86-4.4-RC2.iso -hda /dev/sda

 format the partition already prepared in my case 15G /dev/sda4 also do not install grub if you want to modify it manually from debian partition


 After the install is finished you need to test it first that it works i mount /dev/sda4 to see the dir structure

mount /dev/sda4 /mnt
ls /mnt/
android-4.4-RC2  lost+found

so i have modified /etc/grub.d/40_custom this way
 menuentry "Android-x86 4.4" {
set root=(hd0,4) linux /android-4.4-RC2/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/android-4.4-RC2 DATA= initrd /android-4.4-RC2/initrd.img
}

sudo update-grub2

 and restart choose the new android version

Fire Ruby - howto start with Firebird and Ruby on Ubuntu / Debian

This howto is about installing firebird ruby driver on Ubuntu or any Debian based distro
you might need some firebird dependencies and if you need the stable Firebird server  Firebird 2.5 guide to install it

The very basic firebird package to build only the driver is firebird2.5-dev

sudo apt-get install firebird2.5-dev git-core

and choose yes when asked
Then you need to install ruby and the recommended rails way is to use rbenv 

rbenv install 2.1.2
rbenv global 2.1.2
ruby -v

Best way is to install it from gem

gem install fb

Alternate way  is to build install our gem (latest build-able is located here )

git clone https://github.com/rowland/fb.git
cd fb/
gem build fb.gemspec

You will get something like this in terminal :

 Successfully built RubyGem
  Name: fb
  Version: 0.*.*
  File: fb-0.*.*.gem

Now is time to install it using the gem command

gem install fb-0.*.*.gem

Please read the README.
here is how i tested on my machine

Here is part of the example i ran on my pc

pico test.rb 

And here are the results for my ruby test

ruby test.rb 
ID: 0, Name: John 0
ID: 9, Name: John 9

What is next class ? RoR on Firebird

Compiling Linux Kernel Vanilla - Ubuntu/Debian way

Here is my guide on Compiling x.xx.x Vanilla Final - Ubuntu/Debian using the Debian way

This article is about compiling a kernel on Ubuntu systems. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution.
Install the Required packages for building it

 
apt-get install git-core kernel-package fakeroot build-essential ncurses-dev

Then download latest kernel version

cd /usr/src

sudo su 
wget --continue http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.xx.x.tar.bz2
tar jxvf linux-*.*.*.tar.bz2
cd linux-*.*.*

$ cp /boot/config-`uname -r` ./.config
$ make menuconfig

make-kpkg clean

fakeroot make-kpkg --initrd --append-to-version=-vanillaice kernel_image kernel_headers
cd ..
dpkg -i linux-image-*.*.*

dpkg -i linux-headers-*.*.*
sudo shutdown -r now

you can install the headers too from /usr/src/linux-headers-3.*.*-*
in my case i can show you how the packages are named

ls *.deb
linux-image-*.*.*-vanillaice_4.4.*-vanillaice-10.00.Custom_amd64.deb
linux-headers-*.*.*-vanillaice_4.4.*-vanillaice-10.00.Custom_amd64.deb

I also created a python script http://github.com/mariuz/kernelcompile

that can be used like this

git clone https://mariuz@github.com/mariuz/kernelcompile.git

cd kernelcompile
sudo ./kernel-compile.py

php5 and firebird pdo on ubuntu / debian

The recommendd method is to use the official php5 source from ubuntu or debian and build only the pdo firebird extension and install it

sudo apt-get install php5-dev firebird2.5-dev php-pear devscripts debget

You need to build the pdo extension from php from ubuntu source code here is the source for php package (apt-get source will do the job for any release)

apt-get source php5
cd php5-*
cd ext/pdo_firebird
phpize
sudo ln -s /usr/include/php5 /usr/include/php
./configure
make
sudo make install 

Check to have in php.ini to have the next lines also with phpinfo() function

sudo pico/vi /etc/php5/conf.d/pdo.ini
# configuration for php PDO module
extension=pdo.so
extension=pdo_firebird.so


php -i | grep PDO
PDO
PDO support => enabled
PDO drivers => firebird
PDO_Firebird
PDO Driver for Firebird/InterBase => enabled

you can also check in apache if all is correct
by creating a page in /var/www/pdo_info.php
with this content



then in the browser press F3 and search PDO
to check if all is ok with the driver then create one small example that loads the driver and then is connecting to the database server



after the driver is loaded now you can use the pdo as usual , here is the fetch example
