[elephant-devel] Elephant 0.6.1 Alpha Release available

[Henrik Hjelte]

Great!
Here are some results from sbcl/linux/amd64:

elephant.asd line 113 should be like this:
   #+(and X86-64 linux) "-march=x86-64"

berkeley-db tests:
All tests ok, the first time.
If I run do-backend-tests again, prepares-bdb fails.
However, if I run delscript.sh then all tests run ok again.


sql tests:
(I use postgresql 8.1)

5 out of 115 total tests failed: FIXNUMS, WRITE-64-BIT-FIXNUM, BIGNUMS, 
   RATIONALS, ARRAYS-2.

That is because of a typo that in the end causes the old serializer1 to
be loaded.

The typo is [keyvlaue] should be [keyvalue], line 119 of
sql-controller.lisp in the function create-version-table.

After fixing this, 
everything runs ok.

Migration tests: 
I tried:
(do-migration-tests *testbdb-spec* *testbdb-spec2*)
(do-migration-tests *testbdb-spec2* *testpg-spec*)
Both work I guess, at least they don't show any errors.
But they run awfully fast, and end with the output like this:
Migrating
Migrating class indexes for: IPFOO
Copying the root:
Fetching

MIGRATE-IPCLASS 
MIGRATE-IPCLASS

Does this mean they run ok?

To summarize, it looks really good! Thanks a lot for this!
