[December 28, 2011] Php pdo Firebird Just published # in #ArchLinux User Repository

Ricardo Obregón published the php pdo driver in Arch Linux Repository.


[December 27, 2011] Status of PHP PDO_Firebird as of December 2011

If you have read the previous article about Firebird pdo status then you might now that almost all worked except binding parameters by name (see bug #48877).

But as a gift bug #48877 is fixed in svn, and is already in the php snapshots for 5.4.x, 5.3.x and trunk 5.5.x. So it should all work from the mentioned article. There are still some bugs left but it will be fixed until the end of the year.

PS: I now write the tests and apply the patches for Bugs #47415 and #53280.

[December 23, 2011] Help testing TcpRemoteBufferSize parameter

The parameter TcpRemoteBufferSize found in firebird.conf is supposed to set the maximum size of a packet being transfered. The default value for Firebird is 8K, and the maximum accepted is 32767. Theoretically, bigger packets should make the transfer of large resultsets faster (mostly noticed when connection is high latency networks, aka internet).

Recently, I did some tests with this parameter, but wasn't able to find any differences in the time of a fetchall with a select first 2000 * from some_table_with_no_blobs_and_lots_of_records. A similar test that I did last year, with different FB version and O.S. showed a speed increase of almost 3x in the fetchall time when the packet size was set to 32K, but seems that I cannot reproduce this with my current environment anymore.

If you have some time, please do some tests with this parameter, and publish the results in the comments of this post. Remember to test changing the value at client, at server, and at both, and to mention what Firebird version was used (at server, and client library too, if different). Also, I recommend to run the first select/fetchall at last one time before getting the results, to fill Firebird and O.S. cache and get more accurate results.

If you are a "hardcore" user, you may also want to install Wireshark and have an inside view of the communication process.


[December 22, 2011] List of bugfixes added for next release of FDB Python driver (0.8.0)

Pavel Cisar announced on Python Firebird list:

I forgot to mention that you can use our JIRA tracker to submit bug reports and feature requests for FDB.

And you can check already the TODO list of fixes for the next release.


[December 22, 2011] PowerConsole 0.9.2 realeased and tested with new FDB python driver

Pavel Cisar wrote on google plus about the new PowerConsole:
 
It was tested with new FDB driver (see http://ibphoenix.cz/pwc/ for details), i.e. I've just imported fdb as kdb and skipped the kinterbasdb initialization. Surprise, surprise, it works! All issues I was able to find so far were few small bugs in pwcfb module itself :)

So, I released an update to pwcfb that should fix all issues and sets the dependency to FDB.

To install it simply use `easy_install pwcfb` and it should bootstrap it with all necessary dependencies.

pwcfb 0.9.2 : Python Package Index

Extensive package that enables PowerConsole to work with Firebird databases.

[December 21, 2011] Initial release (0.7.0) of new Python driver for Firebird — FDB is ready for testing

As promised, FDB initial release (0.7.0) is out: http://pypi.python.org/pypi/fdb/0.7.0

It's almost feature-complete (ready for 95% of users), but it could be still buggy (it's beta!), and the code wasn't optimized for size and speed. In all other ways it's ready for wide testing.

What's missing:
  • Distributed transactions
  • ARRAY support
  • EVENTs support
  • Stream BLOBs
  • TRACE service
  • Documentation (but you can use KInterbasDB one as FDB is as close to it as possible)
  • Python 3.x support (haven't had time to test it, but it shouldn't be hard to make it work there)
What's new since my last post here:
  • Support for stored procedures (proper one according to Python DB API, behaviour is the same as in KInterbasDB)
  • Prepared Statements. It works in exactly the same way as in KInterbasDB, i.e. you can use explicit PS via cursor.prep(), or use the internal PS cached for all statements executed via cursor.execute() — it will detect previously executed command and re-use prepared statement (cached per cursor instance!).
  • Fully implemented cursor.description attribute, i.e. including precision for DECIMAL/NUMERIC fields. Should now return the same results as KInterbasDB.
  • trans_info/transaction_info and db_info/database_info calls like in KInterbasDB.
  • Better object dependency and lifetime management, so Python memory GC should be much happier now. I modelled it as much as KDB does it as possible.
Source code is also in Firebird Project's Subversion repository: (KInterbasDB source moved)

Sorry for GIT/Mercurial etc. fans, but Firebird project uses only SVN for all its code (except old obsolete ones that are still in CVS) and it would be pointless to create another type of repository for such a small project. However, you're free to set up mirrors or local repositories on GIT or whatever :)

Merry Christmas to all
Pavel Cisar

[December 12, 2011] Using the Firebird 3.0 API with Delphi

Pierre Yager announced on firebird-devel new version of UIB with Firebird 3.0 API support:

Thanks to Vlad, we achieved the translation of the FB3 OO API in UIB Components for Delphi.

You can checkout the code from SourceForge repository : https://uib.svn.sourceforge.net/svnroot/uib/trunk

Now, we only miss hints to deal with FbMessage, it seems that the examples (fbstuff on github) made by Adriano heavily relies on BOOST and as we don't have such possibilities with Delphi we must understand what is exactly an FbMessage and see what we can do.

Thanks for your help, regards,


[December 12, 2011] Faghmie Davids contributed his patches to firebird provider for gnome db

Here is my patch file so far for the firebird provider. [Ed: For gnome db]

It only run select statements. Your feedback and guidance will be appreciated.

There is still quite a bit missing, but at least I can now select data from a firebird database . Please note that it does not do the input,parameters for statements.....mainly cause I never use it

If there is some interest I'll work some more on it.

Jiri Cincura wrote a new blog post about Sorting using blob column on Firebird:
Imagine you have a blob column and you want to add sorting clause to your query based on that column. Crazy? Might be. On the other hand, why not?


[December 10, 2011] Hierarchical database structures and Firebird PSQL

The idea of storing a hierarchical data in a relational database is very simple, but effective work with such a data requires some knowledge of server-side programming using procedural SQL (PSQL). So the hierarchical data structures are a good chance to get acquainted with PSQL. For demonstration purposes I created a simple database with single table TCLASS containing Delphi class hierarchy

The rest of the article is here.


[December 08, 2011] Future for Python driver merging the pure driver with the ctypes interface to Firebird

Pavel Cisar wrote on firebird python list:

Those who attended my "Python drivers" session at conference in Luxembourg already know that last two months I have worked on another Python driver for Firebird (codename fdb). It was just an experiment how far I could go in short time with another approach to implementation, not real attempt to replace both existing drivers (KInterbasDB and firebirdsql). However, it went so well, that we have a real chance to get out a truly universal pure Python driver for Firebird next year. Here are details...

[November 30, 2011] Jason Wharton talks about FBConference 2011
All,

I would just like to report to the IBO community that the Firebird Conference in Luxembourg was a great success. There were over 60 people in attendance and the sessions I attended were all very good. It's amazing what is being done with Firebird and what is coming in the future. Things are looking very good. The IB Objects session was well attended and it felt like some useful things were learned even by some of the long-time customers. If anyone is interested, the entire session was recorded. I can see about getting permission to put it up on YouTube or to post an MP3 download of it on a file sharing site. Send me a private email.

I think most of the fun we had was getting a personal contact with all the people we rub cyber shoulders with every day. Hopefully in the future there will be more people to come and attend.

I would like to stress the importance of everyone who uses Firebird to consider being a member of the foundation. Your opinions truly matter and your financial contributions are an investment in Firebird's success. All of those who develop Firebird are awesome people. I really enjoyed getting acquainted with them personally. I wish for them to have the means to be compensated financially for their efforts in Firebird. It could be a significant and justified temptation for them to get hired away from their efforts. The best way we can keep their brilliance and talent solely dedicated to Firebird is to give it the resources to secure their interests.

I am working on an idea to give a discount to all those who are members of the Firebird Foundation so if you have some ideas please let me know. I would like to be a strong supporter of Firebird as best I can so I am looking for ways to accomplish this.

Kind regards,
Jason Wharton

Also, how to I configure the SuperClassic server?

This is for Firebird 2.5.


[November 17, 2011] Delphi, Firebird, IBObjects and Transaction Management

I recently had reason to revisit transaction management in our application. The application makes extensive use of data aware grids (TDBGrid) and, as I am sure everyone is aware, it is impossible to explicitly manage transactions when you are displaying data in a grid.

Fortunately, IBObjects provides the means to automatically clean up transactions left hanging by TDBGrid. Unfortunately, this isn’t as well documented or as straightforward as I would like. So, after much research using the programmer’s secret weapon (Google) and a few questions posted to the IBObjects support group (thanks Jason) I think I finally understand how it works.


[November 17, 2011] Firebird + EXT4 + barrier 1/0 + FW ON/OFF

Philippe Makowski did some TPC tests and posted the results at fb-devel:

Hi,

I'm a bit puzzled by the results I get I made test on Fedora 16 with Kernel 3.1.1-1.fc16.x86_64 on LVM2 Logical Volume of 10G

Firebird 2.5.1 Classic

hdparm /dev/vg_tests/testfb
/dev/vg_tests/testfb:
multcount = 0 (off)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 8 (on)

hdparm -Tt /dev/vg_tests/testfb
/dev/vg_tests/testfb:
Timing cached reads: 12976 MB in 2.00 seconds = 6496.46 MB/sec
Timing buffered disk reads: 174 MB in 3.02 seconds = 57.53 MB/sec

database : 1,8G
created with -w20
and buffers 1024

tpcc lanched with -a1 -b1 -W20 -T20 -r1 -R10 -i60
protocol TCP/IP

Scheduler was cfq (deadline scheduler results are really close)

First, on this box (certainly because Fedora 16 use ext4 driver only) ext3 give bad results

so on a database with -write async
for ext4

noatime,async,data=ordered,barrier=1
TPC-C Throughput: 5467.10 tpmC

noatime,async,data=ordered,barrier=0
TPC-C Throughput: 5427.88 tpmC

sync,data=ordered,barrier=0
TPC-C Throughput: 562.11 tpmC

for a raw device
TPC-C Throughput: 6604.00 tpmC

with -write sync
for ext4

noatime,async,data=ordered,barrier=1
TPC-C Throughput: 165.11 tpmC

noatime,async,data=ordered,barrier=0
TPC-C Throughput: 566.89 tpmC

sync,data=ordered,barrier=0
TPC-C Throughput: 568.11 tpmC

for a raw device
TPC-C Throughput: 396.78 tpmC

So reliability have a real cost
hard to have perf and reliability
I really wonder if we can't get MaxUnflushedWrites or something like that under Linux too
I would be curious to do same test with this parameter under Linux

it will not be really safe, but at least a medium solution for people because between
5467.10 tpmC (FW OFF and noatime,async,data=ordered,barrier=1)
and
165.11 tpmC (FW ON and noatime,async,data=ordered,barrier=1) seems that there is a room

Update:
with FW OFF and MaxUnflushedWrites = 100 and MaxUnflushedWriteTime = 5
ext4
noatime,async,data=ordered,barrier=1
TPC-C Throughput: 1155.67 tpmC

as expected between
5467.10 tpmC (FW OFF and noatime,async,data=ordered,barrier=1)
and
165.11 tpmC (FW ON and noatime,async,data=ordered,barrier=1)

but only partially reliable :(


[November 16, 2011] Firebird 2.5.1 final for ubuntu 11.10 published

The package is done (imported from debian repository) with minor modifications (ignoring new dpkg version requirement).

The install guide is the same located in the ubuntu wiki https://help.ubuntu.com/community/Firebird2.5.

I'd like to share vital statistics on the activity, growth, and demographics of this group with you.


[November 14, 2011] ANN: Firebird Maestro 11.11 released

Firebird Maestro SQL Maestro Group is pleased to announce the release of Firebird Maestro v. 11.11, a powerful Windows GUI solution for Firebird administration and database development.

New version features Unicode support in SQL editors and viewers, updated code folding appearance, refactoring of database schema with Split Table wizard, viewing BLOB data as PDF and a lot of other useful things.

Read full press-release.



[November 13, 2011] Firebird 2.5.1 package for Debian Stable named Squeeze

Damyan Ivanov announced:

I have prepared packages from the current version in wheezy (2.5.1.26351), built for squeeze.

ftp://ftp.modsoftsys.net/public/firebird2.5-backports/

If these improve the situation, then we at least know the bug is fixed in that version and can start looking for the exact fix, which would take about 10 iterations (and probably several weeks).

[ED if you want to rebuild them for 32bits you can use these instructions.
