|
||
|
|
|
||
|
|
<p>The following issues and many others have been fixed:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li> The infamous TRAVERSE function has been revamped completely
|
||
|
|
between ASDF 1 and ASDF 2, with many bugs squashed.
|
||
|
|
In particular, dependencies were not correctly propagated
|
||
|
|
across modules but now are.
|
||
|
|
It has been completely rewritten many times over
|
||
|
|
between ASDF 2.000 and ASDF 3,
|
||
|
|
with fundamental issues in the original model being fixed.
|
||
|
|
Timestamps were not propagated at all, and now are.
|
||
|
|
The internal model of how actions depend on each other
|
||
|
|
is now both consistent and complete.
|
||
|
|
As of ASDF 3.3, multiple phases of loading are well supported,
|
||
|
|
wherein correctly interpreting ‘defsystem‘ statements in some ‘.asd‘ files
|
||
|
|
itself depends on loading other systems, e.g. via ‘:defsystem-depends-on‘.
|
||
|
|
The <code>:version</code> and
|
||
|
|
the <code>:force (system1 .. systemN)</code> features have been fixed.
|
||
|
|
|
||
|
|
</li><li> Performance has been notably improved for large systems
|
||
|
|
(say with thousands of components) by using
|
||
|
|
hash-tables instead of linear search,
|
||
|
|
and linear-time list accumulation instead of cubic time recursive append,
|
||
|
|
for an overall <em>O(n)</em> complexity vs <em>O(n^4)</em>.
|
||
|
|
|
||
|
|
</li><li> Many features used to not be portable,
|
||
|
|
especially where pathnames were involved.
|
||
|
|
Windows support was notably quirky because of such non-portability.
|
||
|
|
|
||
|
|
</li><li> The internal test suite used to massively fail on many implementations.
|
||
|
|
While still incomplete, it now fully passes
|
||
|
|
on all implementations supported by the test suite,
|
||
|
|
though some tests are commented out on a few implementations.
|
||
|
|
|
||
|
|
</li><li> Support was lacking for some implementations.
|
||
|
|
ABCL and GCL were notably wholly broken.
|
||
|
|
ECL extensions were not integrated with ASDF release.
|
||
|
|
|
||
|
|
</li><li> The documentation was grossly out of date.
|
||
|
|
|
||
|
|
