Goodbye SVN, welcome GIT

The subversion repository has been dropped and replaced by GIT.
LIXA GIT is available on github.com, as well; the repository on SourceForge is a copy of the repository on GitHub.

LIXA wiki moved

The wiki site used by LIXA project was moved from "Mediawiki" hosted application to native SourceForge wiki.

LIXA 0.9.2 supports new patch scheme for PHP

Release 0.9.2 contains the new patch scheme for PHP previously available only via SVN.

Posted by Christian Ferrari 2012-05-24

Patch for PHP 5.4.3 is available

The PHP team is releasing frequently due to some security fixes.
The LIXA project changed the technique used for PHP source code patching: it's no more necessary a specific diff file for every distinct PHP release.
Now a single diff file can be applied to several distinct PHP source code releases.
If you need this enhancement, please pick-up subversion revision 775.

Patch for PHP 5.4.2 is available

PHP team discovered a security bug fixed with release 5.4.2: http://www.php.net/archive/2012.php#id2012-05-03-1
LIXA project supplies a patch for PHP 5.4.2 to avoid security bugs.
Subversion revision 773 address the issue; alternatively you can use LIXA 0.9.1 and patch manually PHP 5.4.2:

cd ext/php/php-5.4.2
patch -p1 < ../lixa-php-5.4.1-patch.diff

Release 0.9.1 is now available

This release add PostgreSQL to the list of Resource Managers that can be used with PHP language. Is it now possible to develop PHP programs with distributed transaction processing between MySQL and PostgreSQL.

Posted by Christian Ferrari 2012-04-30

Release 0.9.0 is now available

This release integrates the LIXA Transaction Manager with PHP Zend engine and allows a PHP Application Program to manage one ore more MySQL databases (using mysqli driver) in a single distributed transaction with two phase commit.

Posted by Christian Ferrari 2012-04-21

Next release will be 0.9.0

The next release of the LIXA project will be 0.9.0 and not 0.7.5 as it should be if I kept the current release number.
The jump to release 0.9.x is motivated by PHP integration.
I'm working on LIXA & PHP integration and LIXA 0.9.0 will integrate MySQL (mysqli driver) for distributed transaction processing. Integrating PHP and many database drivers will be a long task, so I have decided to dedicate a new release number to the process.
Stay tuned!

Release 0.7.4 is available

This release fixes bug # 3512953: every LIXA & MySQL should update to 0.7.4 asap

Posted by Christian Ferrari 2012-03-31

Release 0.7.3 available

  • A new Resource Manager was tested with LIXA: WebSphere MQ 7.1 (CentOS 6.2 32 bit)
  • A new utility program is available: lixa-config
Posted by Christian Ferrari 2012-03-21

Release 0.7.2 is now available

This release fixes some minor bugs and introduces new parameters for performance and scalability tuning. The documentation has a new performance tuning chapter.

Posted by Christian Ferrari 2012-02-09

Fixed bug 3470598

File release 0.7.1 fixes bug 3470598.
XA XID format id changed from hex to decimal: you might need to adjust some custom developed script.

Beta release (0.7.0)

The first beta test release (0.7.0) of LIXA project is now available for download.
The software and the documentation are complete: it's time to try it in real user environment to discover & fix the residual bugs and promote the project usage.

Future development will follow three distinct paths:
1. I'm going to ask the Community to integrate LIXA with the modules used by other programming languages ( primarily PHP, Python, Perl and Ruby) to access Resource Managers like PostgreSQL, MySQL, Oracle, DB2 and so on
2. I'm going to extend the number of third party Resouce Managers able to interoperate with LIXA (priority will be given to Resource Managers proposed by LIXA users)
3. I'm going to improve the software in these directions: performance, scalability and high availability... read more

Intel/AMD 64 bit porting

Release 0.5.35 has been ported to Intel/AMD 64 bit architecture and passed the tests.

PostgreSQL support

PostgreSQL becomes a managed Resource Manager by the LIXA project Transaction Manager starting with file release 0.5.33

Posted by Christian Ferrari 2011-09-27

LIXA and Oracle Database Server

Release 0.5.30 contains an example that shows how LIXA can be used in conjunction with Oracle Database Server.

Posted by Christian Ferrari 2011-04-19

LIXA manual

Starting with SVN revision 507 - the same feature will be available in file release 0.5.29 - the manual is automatically distributed (make dist) and installed (make install).
The manual is still incomplete, but it will be improved in the near future.

Posted by Christian Ferrari 2011-03-08

lixac_conf.xml changed

Starting with file release 0.5.28 the syntax of the configuration file lixac_conf.xml was changed: "trnmgr" and "trnmgrs" tags was substitued by "sttsrv" and "sttsrvs" tags. The previous tags were misleading because the LIXA State Server is not a Transaction Manager; the Transaction Manager feature is embedded in the "lixac" (client) component.

Posted by Christian Ferrari 2011-03-01

The client/server protocol was changed

Starting from Subversion revision 484 (next file release 0.5.27), the communication protocol between client and server changed: this BREAKS backward compatibility.
A client/server with new code is not compatible with a server/client compiled from old code.

Posted by Christian Ferrari 2011-01-30

New optional flag in lixar command line

A new optional flag for lixar was introduced since subversion revision 388.
The new option is "-e" ("--use-tmendrscan-flag") and it can be used to send TMENDRSCAN flag to the resource manager when recovery scan is completed.
Unfortunately Oracle XE 10.2 does not like this flag, so it is optional: it can be used for other resource managers in the meantime (it maybe the issue becomes more clear in the future).

Posted by Christian Ferrari 2010-09-03

Single thread version removed

The single thread version of the LIXA libraries was removed starting with file release 0.5.18 (see bug # 3045668).
All the Application Programs must link the multi thread version of the LIXA libraries now.
