When debugging C code it is common to write debugging to an external text file using the __FILE__ and __LINE__ preprocessor defines to trace execution flow.
Unfortunately java does not support __FILE__ and __LINE__ but you can get the same functionality with this code which can be placed in one of your libraries.

public static void showTrace(String msg)
{
if (msg.length() > 0) System.out.println(msg);
System.out.println("Trace: " +
"file " + new Throwable().getStackTrace()[1].getFileName() +
" class " + new Throwable().getStackTrace()[1].getClassName() +
" method " + new Throwable().getStackTrace()[1].getMethodName() +
" line " + new Throwable().getStackTrace()[1].getLineNumber());
}
The Komodo Editor is a free project based editor that runs on the mac, linux and windows. It color codes and handles auto completion for lots of languages (including Recital/PHP/Perl/C etc). You can download it free from here.

After an extended period of intense software development, we are pleased to announce the release of Recital 10 which is a milestone in our development efforts.
Recital 10 is comprised of major new versions of all of our products (which are all now Cluster Ready) as well as some new products, and a collection of open source technologies fully supported by ourselves to our customer base.
The Recital 10 release notes can be found here.

- Recital
A powerful scripting language with an embedded database used for developing desktop database applications on Linux and Unix.
- Recital Server
A cross-platform SQL database and application server.
- Recital Web
A server-side scripting language with an embedded SQL database for creating web 2.0 web applications.
Recital is a dynamic programming language with an integrated high performance database particularly well suited for the development and deployment of high transaction throughput applications. Recital 10 further enhances Recital with extensive features and functionality to facilitate its use in fault tolerant high availability systems. Much of the development of Recital 10 was concentrated on performance optimizations and cluster aware functionality to provide an application platform that can be scaled as needed without any application changes.
Key features of Recital 10 include:
- Cluster aware database engine that works transparently with drbd, heartbeat, glusterfs and samba
- High degree of fault tolerance with self healing indexes
- Massive performance improvements
- Extensive internals overall and modernization with superior object-oriented capabilities
- Chronological data versioning with database timelines
- SmartQuery caching
- Database Administration Tools
- Code and Data Profiling
- Better integration with unix/linux command shell
- Incorporates a range of new built-in functions compatible with those in the PHP core libraries
- Built-in support for outputting data in HTML, XML, and JSON format
- Seamless SQL command integration into the Recital scripting language
- Much improved Microsoft FoxPRO language compatibility
- Numerous extensions and improvements (see below for details)
- Very large file support (2^63)
This is a good primer for getting familiar with using Infiniband with Redhat/Centos Linux.

Getting Started with InfiniBand
The first step to using a new infiniband based network is to get the right packages installed. These are the infiniband related packages we ship and what they are there for (Note, the Fedora packages have not all been built or pushed to the repos yet, so their mention here is as a "Coming soon" variety, not an already done variety):
Found a nice subversion plugin for finder on the MAC.
The goal of the SCPlugin project is to integrate Subversion into the Mac OS X Finder.

The first step is to create an Apple Disk Image File (DMG) distribution in a GUI tool, I used DMG Packager.
Then create a directory that will contain all the files that you want included in the DMG file. The best way to do this is to mount the DMG file you created and copy the files into this directory. Then move the .app file created by BitRock into this directory.
Then run the hdiutil utility to create a DMG file
$hdiutil create /tmp/tmp.dmg -ov -volname "RecitalInstall" -fs HFS+ -srcfolder "/tmp/macosxdist/"
Finally call hdutil to convert the writable, to a compressed (and such not writable) DMG
$hdiutil convert /tmp/tmp.dmg -format UDZO -o RecitalInstall.dmg
So now each time before you build a new distribution with the above commands, just move the new .app file into the directory containing the files to be added to the DMG file.
I've already added this to the makefile so after BitRock creates the .app file the hdiutil command is called to automatically generate the new DMG file.
Recital's version of Samba allows application data to be shared and locked correctly across these systems, allowing a truly integrated heterogeneous data environment. For example Recital applications running on a UNIX/Linux server can read and update FoxPro databases residing on a Microsoft Windows NT server through the use of Samba.
You can view the modified changes by downloading the following files and patching these into your current Samba installation.
open.c (file opening and share modes)
version.h (versioning information)
The variable CPPFLAGS in the file Makefile will require the define -DRECITAL added to it.
In order to make the locking compatible between UNIX/Linux and Windows the following environment variable must be placed in the profile.db for Unix/Linux Developer and in profile.uas for the Universal Application Server:
DB_SAMBA=YES ;export DB_SAMBA
The following settings need to be added to the smb.conf file to ensure that file names are always converted to lower case:
preserve case = nodefault case = lowermangle case = yes
The following settings need to be added to the smb.conf file for locking to operate correctly:
oplocks = False
share modes = no
- For building shared libraries on the MAC the following need to be set
-
- The shared library file extension should be .dylib
- The compile flag is -dynamic
- For accessing the shared libraries at runtime
-
- DYLD_LIBRARY_PATH needs to be set to the location of the shared libraries
- Useful utilities for shared library support
-
- The following command will display the table of contents of the dynamically linked library
otool -TV sharedlibraryfile.dylib
