[elephant-announce] Elephant 0.3.0 released
by Robert L. Read 23 Nov '05

23 Nov '05

Elephant 0.3.0 is now released. The following capsule has been added to the introduction section of the documentation, which has a large section describing the extensions in this release: This release, Elephant 0.3, also provides support for relational backends. It has been tested with Postgres and SQLite 3. It is back- compatible with any code that ran against previous versions of Elephant, but also supports simultaneous multi-repository operation and convenient migration of data between repositories. This hopefully allows decisions about the prefered back-end storage mechanism to be delayed and changed, even after an application that uses Elephant is mature. * * * This is the work that was done in the branch SQL-BACK-END, which I have now merged into the trunk of the projects CVS repository and tagged ELEPHANT-0-3-0. (I have also created a tar file and reference in the project homepage: http://common-lisp.net/project/elephant/ If you choose to download and try this release, please send me a note, whether you are successful or have problems. At present I am capable of being very responsive to problems with this system. ---- Robert L.

[elephant-announce] New maintainer and new extention
by Robert L. Read 19 Oct '05

19 Oct '05

I am now the new maintainer of the Elephant project. I don't know much about the history of what has been going on, so please be patient with me and give me as much information as you can. I have recently written a significant extension the original Elephant project. This allows one to use CL-SQL, and in particular PostGres, as a backend. However, the BerkeleyDB system still works and in fact functions are provided to migrate data between multiple co-existing repositories, whether implemented with PostGres or BerkeleyDB. The PostGres system is presently much slower. However, some people may prefer it to the BerkeleyDB system due to the BerkeleyDB license, which does not allow you to build a public website unless your system is all open-source. The extention is checked into a branch of CVS called "SQL-BACK-END". The easiest way to get it, and the extention of the documentation that I wrote, is to do an anonymous CVS checkout of the revision "SQL-BACK- END": cvs -z3 -d :pserver:anonymous:anonymous@common- lisp.net:/project/elephant/cvsroot co -r SQL-BACK-END elephant By doing a "make" in the docs directory, you can construct the HTML based documentation that includes a new chapter on this extension. The file "src/RUNTEST.lisp" shows how to load and run the implementation-specific tests, as well as the migration tests. I don't know how many people are using elephant, or what your desires may be. My basic plan is to wait until mid-November and if nobody has complained enough, to make the SQL-BACK-END version the main version to be released as Elephant 0.3, at which point a tar file will be available. I am not an expert on BerkeleyDB but intend to maintain complete back compatibility with it. This issue is discussed in the new documentation. I intend to actively use this system. I may not be actively developing it, but here is my wish list: 1) SQLite compatibility (estimate: 3 days?) 2) Much more efficient encoding (estimate: 5 days?) Please let me hear from you if you have any interest in this; I am strongly motivated to maintain software that people are using. ---- Robert L.

by Ben 27 Sep '04

Hi folks, I've put a tutorial on the homepage on how to use Elephant with Araneida to make a simple Blog. http://www.common-lisp.net/project/elephant/with-araneida Hopefully this will be helpful. In bad news I found some silly typos in the release I cut, it shouldn't affect most people but I've updated the tarball. Please refresh. Take care, B

Tarballs (and now HTML docs) can be found on the website: http://www.common-lisp.net/project/elephant This release should be a lot more stable than the last. Enjoy!

[elephant-announce] bugfixes
by Ben 04 Sep '04

04 Sep '04

The bad news is: there was a show-stopper bug in the alpha, having to do with OID generation and transaction locks. (I guess that's why they call it "alpha" -- drat.) The good news is: I've fixed it and a ton of other bugs, and added support for OpenMCL! (Thanks to Rafal Strzalinski for finding and fixing one.) The bad news is: there are still some issues with MOP. Mainly, initforms are being evaluated at class definition time. The good news is: those fixes will come soon too -- we're redesigning the slot allocation stuff, and we have to do some CMUCL-wrangling, probably. In the meantime I've repackaged the 0.1 tarball with the fixes I've done. I've also started making a bunch of regression tests (which require the RT asdf package.) I'll make a more formal announcement (and bump the version number) once I finish writing the regression tests, testing OpenMCL et al and produce more docs. The impatient are welcome to try out the tarball of course. The MOP fixes might take some more time, but will happen soon. Thanks for your interest, B

by Ben 30 Aug '04

Andrew and I are happy to announce Elephant 0.1. Tarballs are on the website http://www.common-lisp.net/project/elephant >From NEWS: August 30, 2004 - Elephant 0.1 was released August 30th, 2004. This is an ALPHA quality release, so claims about correctness, performance and safety should be taken with a grain of salt. This release has been tested on CMUCL 19a, SBCL 0.8.13 and Allegro 6.2 on x86 Linux and FreeBSD. OpenMCL and Lispworks versions will come soon. Enjoy, and send in your bug reports! Ben and Andrew
