#RIP #Dudley #GDML in Firebird 3.0 – #Sql won

Leave a comment

Dudley – Sounds like DDL (data definition language) and is the pre (interbase) 4.0 data definition utility GDEF. It’s actually named after Dudley Doright, a character from Rocky and Bullwinkle. GDEF accepts a data definition language based on GDML.

Full thread on Firebird-devel list

Another definition on original source code description (interbase 6.0)

DDL utility. Interpreted commands in the old data definition language (declare relation, declare field – square brackets where you want to put parentheses). Generates BLR for views and triggers, GDML (non-SQL relational language) for metadata updates.

#Django firebird driver project news

Leave a comment

Hello everyone, I want to make a summary of the changes implemented in
recent times about the project django-firebird:

    * More complete exception error messeges (ported from pre-django 1.0
    version)
    * Added a new attribute to obtain the version of Firebird. Useful to
    ensure compatibility with firebird 1.5 and 2.x
    * Implemented the proper support for data conversion. (Issue 8)
    * Fixed bug on with_limits parameter on FirebirdQuery.as_sql. (Issue 9)
    * Fixed bug on autoinc implementation (Issue 3)
    * CHAR is mapped to CharField now (formerly TextField) – (Issue 6)
    * NUMERIC/DECIMAL are mapped to DecimalField now (formerly Integer) –
    (Issue 6)
    * Correct interpretation of RDB$FIELD_SCALE for NUMERIC/DECIMAL fields –
    (Issue 6)
    * Correct consideration of is_null behaviour at field level – (Issue 6)
    * Correct FOREIGN KEY evaluation in get_relations() – (Issue 6)
    * Support for UNIQUE indices for UNIQUE – (Issue 6)
    * Clean and better source code organization.

Remember, this software is still in alpha version, use it at your own risk.

Feel free to try and make any comments on this subject.
We need to add more experience with django and firebird to resolve some
issues. Any help will be apreciated.

Regards.

#Debian gives #FreeBSD some love becomes official part of the distro – Firebird port included

Leave a comment

Firebird does have official ports for debian kFreeBSD and maybe it’s easier to use FreeBSD kernel from an Debian/Ubuntu background (apt-get)

News via tuxradar

Upcoming release of Debian, codenamed Squeeze, will be available in a juicy new FreeBSD flavour alongside the regular Linux version. Well, Debian GNU/kFreeBSD has been around for a while, but now it will be an official part of the distro, combining the titanium-strength FreeBSD kernel with the GNU C library

What is left to be done on the porting front ? maybe fixing the building on avr, hurd and m68k (sh4 is already done) but these are not yet official debian ports.

Also alpha cpu support seems to be dropped from debian release archiectures so no porting effort is needed

I took one list from 2007 and you can compare where we are now

Already ported:
i386
amd64
mipsel
sparc
powerpc
kfreebsd-i386
kfreebsd-amd64
arm
ia64
mips
s390 = IBM/S390
superH (sh4)

Need to be ported:
alpha is dead
m68k
hurd
avr
hppa

ps:
So you can install firebird on the phone (maemo is arm debian linux) or on the mainframe linux (ibm s390)
