Hi,
This started as a simple NVDIMM change, then I realized there
is a Gitlab work item for it [1], so I took the extra
mile and did a bit more. I'll copy/paste here the motivation
for this kind of change, provided by Cole in [1]:
-----
The code that handles domain/VM XML parsing (virDomainDefParseXML in
src/domain/domain_conf.c) has various validation checks sprinkled
within it. Many of these checks should be moved out of the parse step
and into virDomainDefPostParse, so they can be shared by various
places in the code that build a domain definition without XML, such
as converting from native vmware/virtualbox/xen formats.
-----
There are still checks to be moved after this work. If this is
accepted I'll update [1] with more details/tips about how to proceed
with the remaining checks.
Some g_auto* cleanups were done along the way.

For this and the rest of patches - shouldn't changes like this go into
validator callback? I view post parse callbacks as "fill missing values"
not a place to check if configuration makes sense/is valid.

For this and the rest of patches - shouldn't changes like this go into validator
callback? I view post parse callbacks as "fill missing values" not a place to
check if configuration makes sense/is valid.
You mean these callbacks?
---- domain_conf.h ----
/* validation callbacks */
virDomainDefValidateCallback domainValidateCallback;
virDomainDeviceDefValidateCallback deviceValidateCallback;
These callbacks makes sense for driver specific validations, but for what
we're doing here is driver agnostic (well, most of it anyway - probably
there are QEMU specific stuff mixed in).
If we move this logic to say qemuValidateDomainDeviceDef(), then we'll need
to compensate the other drivers that won't have access to these validations
(git grep tells me it's bhyve and vz_driver). Granted, we can put these in
an unique function and use them in the callback for all the drivers, if that's
the case.
Thanks,
DHB

I mean virDomainDefValidate() and more specifically
virDomainDefValidateInternal(). Driver specific callbacks are out of
question - exactly for the reason you pointed out.

Yeah, you can merge those cleanup patches to which I replied with my
reviewed-by.
I vaguely recall that I might merge some patches of your that did
something similar - moved checks from parser to post parse, do you
remember? If so, I'm sorry that I misled you.

Yeah, you can merge those cleanup patches to which I replied with my reviewed-by.
Just did. Thanks for the reviews!
I vaguely recall that I might merge some patches of your that did something similar -
moved checks from parser to post parse, do you remember? If so, I'm sorry that I
misled you.
Nah don't worry about it. It's all learning experience. Besides, the only
one instance I'm recalling doing that ATM is with a NVDIMM code that wasn't
you who merged.
(and this particular code can be moved to the proper place like we discussed
above. I'll keep that in mind when sending the v2).
Thanks,
DHB

New subject: [PATCH 04/21] domain_conf.c: move boot related timeouts check to post parse
This patch creates a new function, virDomainDefBootPostParse(),
to host the validation of boot menu timeout and rebootTimeout
to post parse time. The checks in virDomainDefParseBootXML()
were changed to throw VIR_ERR_XML_ERROR in case of parse
error of those values.

New subject: [PATCH 05/21] domain_conf.c: do not leak 'video' in virDomainDefParseXML()
The 'video' pointer is only being freed on error path, meaning
that we're leaking it after each loop restart.
There are more opportunities for auto cleanups of virDomainVideoDef
pointers, so let's register AUTOPTR_CLEANUP_FUNC for it to use
g_autoptr() later on.

Move it to post parse since it's not related to XML parsing.
Since we don't have a failure test for this scenario, a new
'video-multiple-primaries' test was added to test this failure
case.

New subject: [PATCH 11/21] domain_conf.c: move vendor, product and tray checks to post parse
The 'tray' check isn't a XML parse specific code and can be pushed
to post, in virDomainDiskDefPostParse().
'vendor' and 'product' string sizes are already checked by the
domaincommon.rng schema, but can be of use in post parse time since
not all scenarios will go through the XML parsing.

New subject: [PATCH 14/21] domain_conf.c: remove 'error' label in virDomainDefTunablesParse()
The 'error' label is just doing a 'return -1'.
There's also a couple of 'VIR_FREE(nodes)' calls that are happening
right before exiting on error, but 'nodes' is already set for
autocleanup. These calls can also be removed.

The 'error' label is just returning -1, so let's 'return -1'
directly.
Use g_autoptr() with virDomainControllerDefPtr to remove the
need to call virDomainControllerDefFree() in the error path.
There is no need to VIR_FREE(nodes) explictly since 'nodes'

Hi,
This started as a simple NVDIMM change, then I realized there
is a Gitlab work item for it [1], so I took the extra
mile and did a bit more. I'll copy/paste here the motivation
for this kind of change, provided by Cole in [1]:
-----
The code that handles domain/VM XML parsing (virDomainDefParseXML in
src/domain/domain_conf.c) has various validation checks sprinkled
within it. Many of these checks should be moved out of the parse step
and into virDomainDefPostParse, so they can be shared by various
places in the code that build a domain definition without XML, such
as converting from native vmware/virtualbox/xen formats.
-----
There are still checks to be moved after this work. If this is
accepted I'll update [1] with more details/tips about how to proceed
with the remaining checks.
Some g_auto* cleanups were done along the way.
