Apache module for GCJ
Mon Mar 15 22:04:00 GMT 2004
I did a little experiment last week to embed the GCJ runtime from an
apache module and was surprised to find out how easy that is. The code
doesn't do anything useful, but it creating and accessing the JVM seems
to work well with my setup (SuSE 9.0 standard packages for Apache2 and
GCC). You can find it here here:
This test encouraged me to start a mod_gcj project at sourceforge (I
registered the project, it's now being reviewed by the sourceforge
folks). I'd like to first create an "Apache-native" API that lets people
implement Apache hooks in Java and maps the basic data structures to
Java, and then in a second step try to implement a useful Servlet API
implementation on top of it.
Basically I'm looking for all kinds of feedback and help. It would be
interesting to hear if the code runs for other people. I'm also looking
for contributors. I'm a Java developer and haven't done much C/C++ in
recent years, so some help from that side would be highly welcome.
I also found this message on the mailing list archive:
I think that code might be useful to get started. Somehow the problems
with Apache prefork mode and seem to have been solved in the meantime.
I was able to throw lots of parallel requests at the module with just
one JavaVM initialized running in prefork mode. Also, garbage collection
seems to work ok, at least httpd footprint didn't grow in a notable way
after running a few hundred thousand requests. But maybe that's a
misconception and there's some fundamental mistake with this approach
that I haven't figured out yet ;-)
Let me know what you think/find out.
