If a user invokes 'virsh -c $URI', then within that batch shell, they probably want 'connect' to revert to $URI rather than the normal default URI you get for passing in NULL. In particular, I had a setup where qemu:///session was failing, but took 20 seconds to fail; since 'make -C tests check TESTS=virsh-all' exercises the command 'virsh -c test:///default connect' without arguments, it was locking up for 20 seconds trying to connect to qemu, even though the testsuite specifically wants to limit itself to the test:///default URI. * tools/virsh.c (__vshControl): Add member. (main, vshParseArgv): Set it. (vshDeinit): Clean it up. (cmdConnect): Use it to reopen to original connection. --- This doesn't fix the root cause of this problem: https://www.redhat.com/archives/libvir-list/2012-June/msg00237.html but at least it makes my 'make check' runs faster while I still investigate the root problem. tools/virsh.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 0453b95..b28dc49 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -241,6 +241,7 @@ typedef struct __vshCmd { */ typedef struct __vshControl { char *name; /* connection name */ + char *default_name; /* -c or env-var default when name is NULL */ virConnectPtr conn; /* connection to hypervisor (MAY BE NULL) */ vshCmd *cmd; /* the current command */ char *cmdstr; /* string with command */ @@ -856,7 +857,7 @@ cmdConnect(vshControl *ctl, const vshCmd *cmd) vshError(ctl, "%s", _("Please specify valid connection URI")); return false; } - ctl->name = vshStrdup(ctl, name); + ctl->name = vshStrdup(ctl, name ? name : ctl->default_name); ctl->useGetInfo = false; ctl->useSnapshotOld = false; @@ -19922,6 +19923,7 @@ vshDeinit(vshControl *ctl) vshReadlineDeinit(ctl); vshCloseLogFile(ctl); VIR_FREE(ctl->name); + VIR_FREE(ctl->default_name); if (ctl->conn) { int ret; if ((ret = virConnectClose(ctl->conn)) != 0) { @@ -20176,7 +20178,8 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) ctl->timing = true; break; case 'c': - ctl->name = vshStrdup(ctl, optarg); + VIR_FREE(ctl->default_name); + ctl->default_name = vshStrdup(ctl, optarg); break; case 'v': if (STRNEQ_NULLABLE(optarg, "long")) { @@ -20211,6 +20214,7 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) exit(EXIT_FAILURE); } } + ctl->name = vshStrdup(ctl, ctl->default_name); if (argc > optind) { /* parse command */ @@ -20268,7 +20272,7 @@ main(int argc, char **argv) progname++; if ((defaultConn = getenv("VIRSH_DEFAULT_CONNECT_URI"))) { - ctl->name = vshStrdup(ctl, defaultConn); + ctl->default_name = vshStrdup(ctl, defaultConn); } if (!vshParseArgv(ctl, argc, argv)) { -- 1.7.10.2 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
