Hi, I've been trying out a bash autocompletion file by Geoff Low (slight hack by me, don't blame him for my hack), and it's working pretty nicely. I'm not sure where to put it in the git tree, but it seems like it'd be nice to have upstream? thanks, -serge ==================================================== #!/bin/bash ############################################################################# # # virsh bash completion # Author: Geoff Low (glow(a)cmedresearch.com) # ############################################################################ VIRSH=$(which virsh) function get_main_option_list { # assume options are specified as [--option1 | --option2 | ...] OPTIONS=$(${VIRSH} help | grep '|' | sed -e 's/.*\[$.*$\]/\1/g;s/|//g') } function get_option_list { # get the options for a choice local option=$1; # assume options are specified as [--option1 | --option2 | ...] OPTIONS=$(${VIRSH} help ${option} 2> /dev/null | grep '|' | sed -e 's/.*\[$.*$\]/\1/g;s/|//g') } function _virsh_complete() { local cur prev opts COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" prev="${COMP_WORDS[COMP_CWORD-1]}" cnxn="" i=0 while [[ $i -lt $COMP_CWORD ]]; do if [ ${COMP_WORDS[i]} = "-c" ]; then tgt=`echo ${COMP_LINE} | sed -e 's/^.* -c $[^ \t]*$.*$/\1/'` cnxn="-c $tgt" break fi let i++ done if [ ! -z $tgt ]; then if [ $COMP_CWORD -eq 5 ]; then prev="${COMP_WORDS[0]}" fi fi _all_domains=$(${VIRSH} ${cnxn} --q list --all 2> /dev/null | grep -E "(running|shut off)$" | awk '{print $2,$3}') all_domains=$(echo "$_all_domains" | cut -d " " -f 1) all_networks=$(${VIRSH} --q net-list --all 2> /dev/null | grep 'active' | cut -d " " -f 1) live_domains=$(echo "$_all_domains" | grep -E "running$" | awk '{print $1}') shutoff_domains=$(echo "$_all_domains" | grep -E "shut$" | awk '{print $1}') case "${prev}" in virsh | --help) get_main_option_list ALL_OPTS=$(${VIRSH} -q help 2> /dev/null | sed '1,2d' | awk '{print $1}') COMPREPLY=( $(compgen -W "$OPTIONS $ALL_OPTS" -- ${cur}) ) ;; list) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS" -- ${cur}) ) ;; autostart | dominfo | domuuid | domid | dominfo | domname | dumpxml | setmem ) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $all_domains" -- ${cur}) ) ;; start | undefine) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $shutoff_domains" -- ${cur}) ) ;; create | define) get_option_list ${prev} xml_files=$(ls *.xml) COMPREPLY=( $(compgen -W "$OPTIONS $xml_files" -- ${cur}) ) ;; shutdown | domstate | console | destroy | reboot | save | suspend | resume | vcpuinfo | vncdisplay) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $live_domains" -- ${cur}) ) ;; connect) get_option_list ${prev} URI_TEMPLATES="xen:// qemu:// test:// xen+ssh:// test+tcp:// qemu+unix:// qemu+tls:// qemu+ssh://" COMPREPLY=( $(compgen -W "$OPTIONS $URI_TEMPLATES" -- ${cur}) ) ;; *) COMPREPLY=( $(compgen -f -- ${cur}) ) return 0 ;; esac } complete -F _virsh_complete virsh

VshPrepareDiskXML is to prepare the disk XML for disk changing commands' use, such as detach-disk. The purpose of this patch is to prepare for upcoming new command "change-disk", which will use the two helper functions too.

[libvirt] Add a new api, get this error.gnutls_record_recv: A TLS packet with unexpected length was received.
by chang liu 14 Feb '12

14 Feb '12

hi all, Sorry to disturb you. I wanna to add a new api to get some sheepdog cluster info, but I has get this error, I don't know how to do. I have add a function to daemon/remote.c that call the libvirt.c 's api, remoteDispatchConnectExecuteCommand, and here i get the return value. struct remote_connect_execute_command_ret { remote_nonnull_string ret_val; }; typedef struct remote_connect_execute_command_ret remote_connect_execute_command_ret; static int remoteDispatchConnectExecuteCommand (struct qemud_server *server ATTRIBUTE_UNUSED, struct qemud_client *client ATTRIBUTE_UNUSED, virConnectPtr conn, remote_message_header *hdr ATTRIBUTE_UNUSED, remote_error *rerr, remote_connect_execute_command_args *args, remote_connect_execute_command_ret *ret) the return value has been in ret->ret_val. I know the func remoteDispatchDomainDumpXml returns it's values by ret->xml. And after this, the things is the same, but when I dump xml, it's ok, but when i wanna to get my value, it's cause this error: error : qemudClientReadBuf:1708 : gnutls_record_recv: A TLS packet with unexpected length was received. Could any body tell me, if I wanna to get a string data, do I need to do any additional actions?
