# HG changeset patch # User cl349@xxxxxxxxxxxxxxxxxxxx # Node ID 932fc8a1b38d0c93d0445843ff5bebd090b129ee # Parent d63b100b327ab8354bc9a71c38dbca436c64c0a5 # HG changeset patch # User Rusty Russell <rusty@xxxxxxxxxxxxxxx> # Node ID a92163adedcfcff0d05c965d09da747f3c8aa13e # Parent 63ab20781afa311300f3a8e832744292014ea7f6 Remove ill-conceived concept of watches blocking reply on connection which did write/mkdir/rm/setperm etc. This causes deadlocks in real life, and I can't see a sane way of avoiding them: it is reasonable for someone to ignore watch notifications while doing other actions, and that means that we can do other writes. These writes can block pending other watchers; if one of these is the process blocked awaiting our ack, we deadlock. diff -r 63ab20781afa -r a92163adedcf tools/xenstore/xenstored_core.c _______________________________________________ Xen-changelog mailing list Xen-changelog@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-changelog |
