[libvirt] [PATCH v2 10/11] domain_conf: Introduce VIR_DOMAIN_DEF_PARSE_SKIP_POST_PARSE

This is an internal flag that prevents our two entry points to XML parsing (virDomainDefParse and virDomainDeviceDefParse) from running post parse callbacks. This is expected to be used in cases when we already have full domain/device XML and we are just parsing it back (i.e. virDomainDefCopy or virDomainDeviceDefCopy) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- src/conf/domain_conf.c | 8 ++++++++ src/conf/domain_conf.h | 2 ++ 2 files changed, 10 insertions(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index b11a296..bd20b74 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -4428,6 +4428,10 @@ virDomainDeviceDefPostParse(virDomainDeviceDefPtr dev, { int ret; + /* fill in configuration only in certain places */ + if (flags & VIR_DOMAIN_DEF_PARSE_SKIP_POST_PARSE) + return 0; + if (xmlopt->config.devicesPostParseCallback) { ret = xmlopt->config.devicesPostParseCallback(dev, def, caps, flags, xmlopt->config.priv, @@ -4577,6 +4581,10 @@ virDomainDefPostParse(virDomainDefPtr def, .parseOpaque = parseOpaque, }; + /* fill in configuration only in certain places */ + if (parseFlags & VIR_DOMAIN_DEF_PARSE_SKIP_POST_PARSE) + return 0; + /* this must be done before the hypervisor-specific callback, * in case presence of a controller at a specific index is checked */ diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 39d7d8c..699e237 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -2645,6 +2645,8 @@ typedef enum { VIR_DOMAIN_DEF_PARSE_ABI_UPDATE = 1 << 9, /* skip definition validation checks meant to be executed on define time only */ VIR_DOMAIN_DEF_PARSE_SKIP_VALIDATE = 1 << 10, + /* skip post parse callback */ + VIR_DOMAIN_DEF_PARSE_SKIP_POST_PARSE = 1 << 11, } virDomainDefParseFlags; typedef enum { -- 2.8.4
