I'd been meaning to answer this, but got swamped by all the other emails :-) The policy that we followed with Martin Sustrik while maintaining ZeroMQ was to avoid external dependencies where possible. Any external dependency creates a burden on users, distributors (Debian, etc.) and maintainers of the depending project. The major exception was OpenPGM, which got packaged with libzmq both because originally we used a specific version, and because a significant part of our target user base are people who want to use PGM multicast. A major part of software development (IMHO) is knowing what to keep "out" just as much as what to put "in". Keeping the libzmq core lean & mean follows this principle. Regarding Judy, I had a brief look at the website, and grabbed the code. The download is a ~1MB tarball, and a quick count of the "src" directory gives: $ find . -type f | xargs wc -l [...] 29314 total Doing the same for libzmq master gives: 20352 total So, if it were my decision, I would need to consider the benefit of Judy arrays vs. the cost of including 29000 lines of code (more than libzmq core!) as a dependency. Of course, there is no such policy now, so feel free to submit a patch! -mato _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
