Dimitios, thanks for your report. > I failed to clone the tryton-env repository after enabling subrepos. > I have confirmation it works on the same network config under Linux. mercurial subrepos shouldn't be the problem here. to resume a bit the problem: mercurial fails to clone a repository, the connection is aborted with ECONNRESET (Connection reset by peer). To reproduce: $ hg -v --traceback --config subrepos.allowed=true clone https://hg.tryton.org/tryton-env The issue is reproductible on OpenBSD, but not on others OS: - cedk (tryton developer) reproduced it on OpenBSD and not on Linux on the same network (not a network problem) - I tested it on ipv4 and ipv6 network (both failed) - juanfra@ already looked at it too, and confirmed that dragonfly (with libressl) doesn't have the problem as us mercurial port has no patches, it moves the problem on OpenBSD side. >From analysis with wireshark of the network connection, it seems that the tcp stream is a bit "chaotic" (ipv6 here): - wireshark complains: - regulary with "New fragment overlaps old data (retransmission?)" - some "TCP Previous segment not captured" (so I assume not received as it is during the capture and not at start) - few "TCP Dup ACK" - received frame len of 1506 (whereas my local re0 mtu is 1500 / on router pppoe0 mtu 1492, vlan mtu 1500, re0 mtu 1504) - ipv6 payload len 1452 - tcp segment len 1420 and just before ECONNRESET: - receive a packet: wireshark note that "TCP Window Full" - my host ACK with Win=0 "TCP ZeroWindow" - some exchange "TCP Keep-Alive" received and "TCP ZeroWindow" sent during ~5-6second - receive RST,ACK packet > My machine(s) are running 6.8 on amd64, tested my main machine and a vps from > openbsd.amsterdam.
