[zeromq-dev] iMatix: old download.zeromq.org disk image -- last call
Hi, iMatix used to host the ZeroMQ downloads, at download.zeromq.org, on a Gandi VM. About a year ago the ZeroMQ downloads were moved from that Gandi VM to (a) GitHub (most newer releases), and (b) archive.org via a redirector service now pointed to by download.zeromq.org, for older historical releases. Now that it's been about a year since the old Gandi VM was shut down, I've been planning on finally deleting the disk image of the old Gandi VM -- it's costing a few Euro a month to keep around, and given no one has asked about it in the last year, it seems time to let it go. When checking on the disk images status I also found a Gandi announcement from May: https://news.gandi.net/en/2017/05/moving-to-our-new-datacenter/ that they are closing the data centre those disk images live in, in November. So that probably sets a final time to do something with the disk images if we need them, ie in the next two months. Before I deleted the disk images, I thought I'd ask whether there was anything else, not already online elsewhere, that someone was hoping would be recovered from download.zeromq.org or other iMatix download hosting. (In theory it might be possible to find afterwards out of the disk images of iMatix's other main server, but the Gandi VM is definitely the easiest thing to put back online quickly, before the disk images are deleted.) Please let me know directly if you have any reason why these iMatix disk images should be kept and/or put back online for a while so something can be retrieved. If I don't hear anything by Wednesday 6 September I'll probably finally delete the disk images later that week. Thanks, Ewen ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org https://lists.zeromq.org/mailman/listinfo/zeromq-dev

Note that multi-part is needed for atomic delivery of messages - iow: either all parts are delivered with guaranteed ordering or none is. UDP means no guarantees on delivery and ordering. If that's not a feature you require, than you could do without. Also note that zmq_send_const, as the manpage and name suggest, it's for constant memory only, eg: zmq_send_const (socket, "constant string", ... For zero-copy for non-constant buffers look at zmq_msg_init_data. radio/dish over udp multicast (ipv4) can work with zmq_msg_init_data. -- Kind regards, Luca Boccassi signature.asc Description: This is a digitally signed message part ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org https://lists.zeromq.org/mailman/listinfo/zeromq-dev
[zeromq-dev] Rare feature combination possible?
Hi all, I would like to send Multi-Part Messages via a zmq_send_const(..) call over a RADIO socket through UDP at a Multicast Address. So is it possible to: - Send Multi-Part Messages - Send Messages with Zero-Copy (e.g. via zmq_send_const) - Send over a RADIO socket and receive it at a DISH socket - Send over the raw UDP protocol - Send to a multicast address (e.g. 244.0.0.1) If not, which feature do I need to drop? UDP and Multicast are actually a must have for me. Zero-Copy and Multi-Part Messages are somehow bind to each other, as I try to send data from different locations in memory in one multi-part message. About the socket type I don't care, but I read often that UDP only works with RADIO/DISH. What is the current status in ZMQ Version 4.2.3?

Hi, I would really love to be part of that. I need to see if I can arrange that.
