Still got 256m of free memory for ngnx , php , or something better a node.js experiment Let's create/use a database and see simple firebird at work

gunzip employee.fdb.gz

Later i will try firebird c api examples
cd /usr/share/doc/firebird2.5-common-doc/examples/api 
cp *.gz ~/
chown pi.pi *.gz
cd ~
gunzip *.gz
gcc -L/usr/lib -lfbclient -I/usr/share/doc/firebird2.5-common-doc/examples/include/ api1.c
ISC_USER=SYSDBA ISC_PASSWORD=masterkey ./a.out /tmp/new.fdb
Created database '/tmp/new.fdb'.

Successfully accessed the newly created database.
So all it works as it should without errors and at the speed of pentium 2 like system or even faster I love the small server and i can leave it on 24x7 without the need to think too much for the energy costs
Next i have tested the firebird python driver fdb
sudo apt-get install python-pip
 

pip install fdb
cat test.py
con = fdb.connect(dsn='/var/lib/firebird/2.5/data/employee.fdb', user='sysdba', password='masterkey')

cur = con.cursor()
SELECT = "select * from employee"



# 2. Equivalently using fetchall():
# This is potentially dangerous if result set is huge, as the whole result set is first materialized
# as list and then used for iteration.
cur.execute(SELECT)
for row in cur.fetchall():
    print 'ID:%d Name %s.' % (row[0], row[1])


python test.py
....
ID:141 Name Pierre.
ID:144 Name John.
ID:145 Name Mark.

Next on my testing list is compiling the node.js (doing it rightnow) and the pure JavaScript Firebird driver with an express demo Update : compiling node is done here are my results

Have you tried or do you have a preferred webserver to use with pi and firebirdsql?

node contains also a web server but if you want to serve static content fast i recommend nginx
