Referring to the last question: Hibernate-D is *not* based on

But I have already been looking into the idea of using
Hibernate-D and
Vibe.d together. In fact, my recent commits to mysql-native
adding
support for Phobos sockets was a big part of that.
The main issue is that Vibe.d programs should be using Vibe.d
sockets instead of ordinary sockets (I don't know what would
happen if
you don't use Vibe.d sockets. My guess is it just wouldn't
happen
asynchronously, but Sonke could answer that better). But
Hibernate-D
aims to be usable even without Vibe.d, so it uses Phobos
sockets for
MySQL (via a modified fork of an older mysql-native), and for
PostgreSQL
and SQLite it just uses the C libs.
I've already converted mysql-native to support both Vibe.d and
Phobos
sockets, and I've already created a branch of Hibernate-D that
makes
Hibernate-D use the new official mysql-native and therefore
automatically switch to Vibe.d sockets whenever Vibe.d is being
used
(detected by -version=Have_vibe_d, which is automatically added
by DUB
is you're using both Vibe.d and DUB). But G^DF*^@CKD*#MMIT I
*just now*
noticed that commit (and the pull request I could have sworn I
made)
seems to have completely disappeared without a trace...Shit, I
gotta
figure out what happened and where the hell it went...
Ugh, anyway, I've been digging through Hibernate-D's source the
last
couple days checking out what else might be needed. As long as
I get my
magical disappearing commit resurrected, it *looks* to me like
the only
other thing that might be needed is to bypass Hibernate-D's
built-in
connection pool. Even that might still work as-is (I haven't
tried),
but it's not really necessary for Vibe.d users since Vibe.d has
its
own fiber-safe connection pool system. But it's pretty easy to
bypass Hibernate-D's connection pool in favor of Vibe.D's
connection pool in user-code without even patching Hibernate-D.
AFAICT so far, it looks like everything else in Hibernate-D
should work
fine with Vibe.d.
tl;dr:
Hibernate-D does not use Vibe.d, but I have personal interest
in using them together and I've been checking into it. Not sure
what
can be done about PostgreSQL and SQLite (I *think* they'll work
but
just not asynchronously - not sure what else can/should be
done, I'd
have to ask Sonke). But for MySQL, all you *should* need is a
patch or
two that I've been working on.
Regarding PostgreSQL, keep in mind that it has an async API,
which would be handy in building a Vibe-friendly wrapper:
