Re: [libvirt] [PATCH 6/6] virsh: Add build flags to pool-create[-as] and pool-start

https://bugzilla.redhat.com/show_bug.cgi?id=830056 Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in order to pass the flags along to the virStoragePoolCreateXML and virStoragePoolCreate API's. This affects the 'virsh pool-create', 'virsh pool-create-as', and 'virsh pool-start' commands. While it could be argued that pool-start doesn't need the flags, they could prove useful for someone trying to do one command build --overwrite and start command processing or essentially starting with a clean slate. NB: This patch is loosely based upon code originally authored by Osier Yang that were not reviewed and pushed, see: https://www.redhat.com/archives/libvir-list/2012-July/msg00497.html Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- tools/virsh-pool.c | 73 +++++++++++++++++++++++++++++++++++++++++++++++++++--- tools/virsh.pod | 25 ++++++++++++++++++- 2 files changed, 94 insertions(+), 4 deletions(-) diff --git a/tools/virsh-pool.c b/tools/virsh-pool.c index cb91cd3..1bb987d 100644 --- a/tools/virsh-pool.c +++ b/tools/virsh-pool.c @@ -47,6 +47,13 @@ .help = N_("file containing an XML pool description") \ }, \ +#define OPT_BUILD_COMMON \ + {.name = "build", \ + .type = VSH_OT_BOOL, \ + .flags = 0, \ + .help = N_("build the pool as normal") \ + }, \ + #define OPT_NO_OVERWRITE_COMMON \ {.name = "no-overwrite", \ .type = VSH_OT_BOOL, \ @@ -235,6 +242,9 @@ static const vshCmdInfo info_pool_create[] = { static const vshCmdOptDef opts_pool_create[] = { OPT_FILE_COMMON + OPT_BUILD_COMMON + OPT_NO_OVERWRITE_COMMON + OPT_OVERWRITE_COMMON {.name = NULL} }; @@ -246,15 +256,32 @@ cmdPoolCreate(vshControl *ctl, const vshCmd *cmd) const char *from = NULL; bool ret = true; char *buffer; + bool build; + bool overwrite; + bool no_overwrite; + unsigned int flags = 0; virshControlPtr priv = ctl->privData; if (vshCommandOptStringReq(ctl, cmd, "file", &from) < 0) return false; + build = vshCommandOptBool(cmd, "build"); + overwrite = vshCommandOptBool(cmd, "overwrite"); + no_overwrite = vshCommandOptBool(cmd, "no-overwrite"); + + VSH_EXCLUSIVE_OPTIONS_VAR(overwrite, no_overwrite);
