Released 3.3.8. Fixed a big bug in remove introduced in the last version.
Changed all of the routines to use appropriate print formatting defines
from <inttypes.h>
03/21/2013
Rleased 3.3.7. It's been a long hiatus. But someone using a more recent
compiler downloaded the package and reported problems in the C++ routines.
I took advantage of the time to re-work the index sorting and searching.
This improved sorting time by more than 25 percent. Also fixed a bug in
the transaction processing that would hang the server. Changed the C++
library to define the Datman namespace, and to bring it up to complience
with newer compilers.
09/25/09
Released 3.3.6. Fixed a bug in the server when you used keys that are 32
characters long, and finally removed the '-release' flag when building the
libraries. The upshot of this is that you can upgrade the library without
re-linking your application against it. Makes it easier when you want to
add something to the library and not your application.

Interesting news.... I seem to now have a corporate sponsor. Well, really
what has happened is that my place of employment is using this project and
as a result lets me work on it during the day. Sometimes.
Again, there have been no updates for a long time. Mostly because things
were working pretty good for what I wanted. I've now fixed a few bugs, and
added a couple of relational operators in the c++ clientlib. I've posted up
the changes to SourceForge as release 3.3.5 (the prior attempt at 3.3.5 was
withdrawn pretty quickly because the freelist was a -really- bad idea.)
I would still LOVE to hear from those of you who download this project just
to know what you are using it for. It's not mandatory, but it's something
that will at least let me know what's going on out there
08/03/08
My server crashed with several hardware failures which has caused the site
to be down for a couple of weeks while I got together a new system. It seems
as if everything is now functional, and that I'll be able to post a couple
of bug fixes in the near future.
05/29/08
Fixed a problem with the server thinking an open datafile was closed. Added
a freelist so that when many records are deleted, space in the datafile is
used more efficiently.
Released ass 3.3.5
04/14/08
Fixed the dbclean utility. If there were blobs associated with a file that was
rebuilt, they wouldn't be reassigned to the newly moved record.
If dataman is already up and running, you may re-invoke it with the '-D' switch
to toggle on and off debugging. You can do it manually by sending SIGUSR1 to
the dataman_srv and dataman_con processes.
dfedit would crash if you entered a record number that corresponded to a
deleted record. You can now do that and potentially un-delete that record.
mkdf would not delete the blobs associated with a datafile that was being
re-built.
I decided to leave the library files at level 3.3.3 since there was no changes
whatsoever to the client libraries.
Released as 3.3.4
01/03/08
Added command sequence checking in the database server. Up to this time, I've
basically assumed that any connections from a client was benign, and that no one
would want to send malicious packets. Well, now there is more checking to verify
packets.
Released as 3.3.3
10/11/07
Well, it's been about a year since I've posted anything here. I've mostly taken
the time off. This release fixes some largefile bugs, and finally officially adds
the clean utility. The very old and buggy code has always been in the respository,
just not ever made to work. This release includes that, and rolls together the
changes made a year ago, but not rolled into a package. Added all together, this
makes release 3.3.2
12/4/06
Finally commited index file name handling for dumpix and utilities to take
advantage of the new functionality of mkidx. Data file names in Dataman
still can be at most 63 characters long (do you really want to have file names
longer than that?).
11/1/06
Implemented better handling of file name arguments to mkidx. Now an index can
refer to an arbitrarily large number of files. Added the sort program verbs to
php, so scripts can now build a new index. This was added to CVS. I'll roll a
new release in the future.
10/25/06
Was able to do testing on a 64 bit system. There was a problem with creating a new
record in a transaction. That has been fixed and the changes posted. The 3.3.1
package was re-posted as well to reflect the change. In either case, getting the
source package, or the CVS tree will have all the changes. Oh, and evertying worked
as expected
10/21/06
Finally the 3.3.1 release has been posted up to SourceForge. There have been lots of
changes and it's nice to have everything in the release package. The transaction
processing code, the changes to the C++ API and the documentation are all there (and
here as well!). I haven't tested everything on a 64 bit system yet, but that should
be coming in the next week or two.
09/15/06
I've finally added some documentation for the C++ API library. I know it's been a long
time coming, and should look better than it does, but hey, at least it's there. The
entire documentation tree will be included in the next release package that also includes
the transaction processing functionality.
08/23/06
I know there haven't been many changes on the website for a while, but that is because
I've been busily working on transaction processing. If you are interested in testing
this, please let me know and I'll send you the new code. There are three new verbs
(and of course, since they are new, they're not EDITOR verbs); start_transaction(),
commit(), and rollback().
06/17/06
Two more bug fixes in the server have been put in CVS on SourceForge. This should clear
up some obvious problems for some.
06/01/06
There have been changes for 'protected' memebers of the java classes, actually, making
them not protected, but only package level availability. This should reduce some
confusion of how to use some of the methods.
05/29/06
The java API documentation has now been posted up. I know it's been a long time coming,
but at least it's here now. It was created with javadoc (I finally learned more about
that). I'm working at re-re-writing the c++ doc, and that should be available soon. When
that is done, I'll put it all in a new release, and post it up to sourceforge.
05/18/06
Of course, the day after I post a release, I notice something left over from cleaning
up, and it broke db_discon.c That has been fixed and is available in the CVS repos.
05/17/06
Version 3.3.0 has been released. I know it's been a long time since the last release,
but hopefully the changes were worth the wait. This makes some major changes in how
the server runs. First off, I've finally compiled things on a 64 bit CPU and made the
changes necessary to run successfully on both 32 bit and 64 bit CPUs. You may now
specify how many threads the server will run, and the size of the shared memory segments.
There has been a longstanding bug in the delete() function that has finally been fixed.
Overall, the changes have resulted in about a 12% increase in server speed.
12/29/05
Version 3.2.5 has been released. If you've been keeping up with the CVS changes, this
rolls up the chages found there. I'll admit that in the last few days there were several
changes posted, and that is what convinced me to roll up another release. None of the
interfaces in the libraries have changed.
11/30/05
The code for the PHP module has been released as a seperate package and has it's own
CVS repository. This should make it easier to 1) download the package, and 2) update
the code. It currently has only been tested with PHP 5.0.2.
10/15/05
Hopefully, the power company have finally sorted out the power problems, and this site
can be more available.
10/01/05
There have been many power problems of late. Please bear with as these get sorted out.
The current news is that version 3.2.4 has been released. This release changes the
datafiles and indexes to 64 bit. This means that a single datafile can be up to 9.22x10^18
bytes if your operating system supports it. Some effort to support concurrency for multi
threaded web servers has been added to the php module as well.
Examples for C, C++ and java are now beind distributed, and this web page is now available. The
documentation is now being updated to match the current version, and is available only in HTML
pages on this website. Currently only the C API is finished. The C++ documentation shoud be
available shortly, followed by PHP and Java.
PHP documentation is available. It's mostly in the style of the function reference page
for PHP modules found on their website. I didn't write seperate pages and allow for user
comment. Perhaps that will be forthcoming. It was just important to get the documentation
up for those of you downloading it.
This web page will be updated soon to be a bit more attractive in the near future as well.
