Here is initial port result available for early experiments. It
can be compiled with make -f posix.mak GC_TYPE=concurrent and
passes the test suite with only shared library tests disabled
(ef20b7a).
There are still many issues to be aware of:
1) Documentation is largely missing. Working on it, reading
@leandro-lucarella-sociomantic old posts
(http://www.llucax.com.ar/blog/blog/tag/understanding%20the%20current%20gc)
may help in the meanwhile
2) Code style differs from Phobos standards. To be fixed soon.
3) Shared library support is completely missing. Proxy
infrastructure similar to one in existing gc needs to be added
and I don't know if actual implementation will work in such
environments or more changes will be needed.
4) Deadlock issue
(http://www.dsource.org/projects/tango/ticket/2087) still
remains. It is not critical to our code because it almost never
uses threads so no big effort was put into it but this can be
huge problem for any other project.
In general this is very far from something that can be merged
upstream straight away and replace default GC on linux. It can be
interesting for other projects with similar architecture and
requirements and probably helpful for anyone else working on
better D GC.
