[bknr-devel] SBCL and OpenMCL ports done properly
by Hoan Ton-That 09 Feb '06

09 Feb '06

Hey everyone, I've ported the datastore to SBCL and OpenMCL properly. I'm sorry to everyone else who has been kept waiting. The format of the transaction log in UNCHANGED. I've tested loading, creating, and snapshotting across CMUCL, SBCL and OpenMCL with all primitive datatypes (array, integer, symbol, string, list, hash-table, single and double floats), as well as other compound objects. The patch is against the latest svn repository. Apologies again for this not being up sooner. Hans, if I were to change one thing about the current transaction log format, it would be the encoding of floats and double-floats. I think it would be better to use integer-decode-float (because it is in the hyperspec), than all these read-time conditionals. I couldn't find a `make-single-float' and `make-double-float' for OpenMCL. I can easily do this for you and I'll even write a converter if you wish. Hoan

[bknr-devel] SBCL port
by Tchadvar Roussanov 04 Feb '06

04 Feb '06

Hi, I am trying to compile BKNR with the latest SBCL release. Till now I had to update almost all third party libraries to their latest versions. Is there are plans to update the versions of these packages in the SVN tree? Or move them out and use asdf install to resolve dependencies? I also notice in the SVN repository that there is ongoing SBCL porting effort. What is the current status of it? I am willing to help with this port as much as I can. Thank you.

Re: [bknr-devel] string multiple-slot indices
by Hans Hübner 02 Feb '06

02 Feb '06

Hi Kamen, we have used the array-index in an application that stored map locations referenced by a coordinate. The coordinate is stored in x and y slots of the objects, and we wanted to retrieve objects by coordinate, without writing a special purpose index for the application. The array-index class is only good to index objects with multiple slots that have integral values. There is nothing I can see that precludes other multiple-slot indices which would accept string values, but that would be more involved to implement. The dimensions of the index array are required to set up the array that holds the index. I hope that this answers your question. Cheers, Hans

[bknr-devel] string multiple-slot indices
by Kamen TOMOV 31 Jan '06

31 Jan '06

Hi, Is multiple-slot indices only for slots that are numbers? I tried with a multiple-slot array-index where one of the values is a string. It signaled a condition. What is the proper way to do that? Also I noticed that their size needs to be specified. Why is that? Thank you. -- Kamen TOMOV

[bknr-devel] threads with bknr-datastore
by Kamen TOMOV 27 Jan '06

27 Jan '06

Hi, Is bknr-datastore thread save? If we call the function make-blob-from-file it would create a blob object and will start copying the file. It seems to me that if we access the object before copying is completed its state would be undefined. Is there a known workaround? It should be some mechanism for locking/unlocking of blob objects. Thanks. -- Kamen TOMOV

[Bknr-devel] BKNR Subversion repository
by Erik Huelsmann 23 Jan '06

23 Jan '06

Hi! Erik Enge asked me to test his Subversion setup for him. As you are the first project he could think of actually using Subversion, I tried your repository. Although the test succeeded, the checkout of your repository failed. As a Subversion developer, I run an svn-trunk client. This client has lots of changes to the working copy code (the new 1.4 release will have many working copy improvements), so it may be well because of it that the checkout failed. But in order to diagnose the problem, I'd like to know a few things about your repository: - Did you create it with the Subversion supplied on common-lisp.net? - After creation, how did import old history? - If you used cvs2svn, which version did you use to generate the dumpfile? - Do you have any problems yourselves with checking out the repository? Thanks for helping me analyse before this becomes a problem in 1.4! bye, Erik.
