Dear Raphael,
Thanks again for fixing this pickle matter and sorry for the delay. I
just updated my SVN trunk, and tried compiling the trunk and testing
whether loading old pickles works.
However, it appears I am unable to compile. I don't know whether I am
just stupid ( I did this before..), or whether there is actually some
problem. I tried various things, but always get the same error message.
Here is what I am doing. I create some build directory, move into that
build directly and then evoke the mozart configure script from within
the build directory, e.g.,
$ cd /path/to/build/dir
$ /path/to/mozart/trunk/mozart/configure --disable-contrib --disable-doc
$ make
Then I get the following error.
Makefile:17: /path/to/mozart/trunk/share/Makefile.boot: No such file or
directory
make[2]: *** No rule to make target
`/path/to/mozart/trunk/share/Makefile.boot'. Stop.
make[1]: *** [bootstrap] Error 1
make: *** [bootstrap] Error 1
Torsten, strange error, but I think I've seen it before. Could it be that svn
doesn't make a correct checkout of the project? I remember that once I had a
similar problem and I decided to remove the whole source dir and run checkout
again. The problem was gone. I remember to have seen some differences between
the Makefiles.
Raph, as soon as I run some tests with the last revision I'll let you know.
cheers

For some reason, the makefile tries to access a
directory /path/to/mozart/trunk/share. I assume that should
be /path/to/mozart/trunk/mozart/share.
What am I missing? Thank you!
Best

Dear Torsten,
I checked in a change in the svn trunk of Mozart. Can you give it a
try? I personally tested it with the Oz Minesweeper applet, which was
still in the former pickle format, and it worked :-)
If testing succeeds, I will include it in the maintenance branch, and
maybe push for a Mozart 1.4.1 release.
Cheers,
raph

I had a look at the changes between releases. The only change
in the pickle format is its extension to pickle failed values.
The other changes simply reflect the reorganization of the
internal class hierarchy of values, they do not affect the
format itself.
I will give it a try soon (probably during the weekend). If
it works, I will commit it to the svn trunk, and ask people to
test it. If testing is successful, I will call for a minor
release of Mozart (1.4.1).
Thank you very much indeed! You are actually suggesting more than
I even hoped for :)

Yes, this is exactly what I am suggesting. I don't pretend
that it is possible for all former pickler versions. But I
think that backward compatibility with version 3#3 of the
pickler (Mozart 1.3.x) is feasible.
This requires a careful review of the diff between both
versions of the pickler. This is not an easy task, since that
part of Mozart is quite low-level and a bit obscure (to me at
least). And one must make sure that the compatibility test
only applies to pickles.
Cheers,
