This series has a lots of cleanups to prepare lxc to handle network
settings for verion 3.0 or higher. The new version is considering
network indexes to define network interfaces. i.e.: "lxc.net.X.".
As we need modular structures to support both versions, this method
needs a cleanup before accepting new features for version 3.
Obs: this version does not include any new feature for LXC 3.0 network.
Julio Faracco (6):
lxc: Create a separate method to handle IPv{4,6} outside parser.
lxc: Create a new method called lxcNetworkParseDataEntry().
lxc: Converting full string entries in types only.
lxc: Refactoring lxcNetworkWalkCallback() to a simple method.
lxc: Create a method to initialize network data outisde.
lxc: Converting 'if,else' logic into a 'switch,case'.

The new method called lxcNetworkParseDataIPs() is responsible to handle
IPv{4,6} settings now. The idea is let lxcNetworkWalkCallback() method
handle all entries related to network definition only.

When adding new functions we like to see 2 blank lines before/after each
method and each argument for the method on it's own line.

New subject: [libvirt] [PATCH 2/6] lxc: Create a new method called lxcNetworkParseDataEntry().
This new method is responsible to verify is the settings correspond to
network entry. Right now, it is only verifying "lxc.network.", but in
the future, it can be used to verify "lxc.net.X." too. Any other case
would be rejected.
On the other hand, the idea here is working only with types. If we know
that entry is part of network settings, after we just need to know which
type is. It keeps the hanlder simple.

Same thoughts as before w/r/t method headers.
However, because we require each patch to be able to compile separately,
things won't work in this order as lxcNetworkParseDataEntry is a static
method with no callers.
What needs to be done is this move this above lxcNetworkWalkCallback and
then merge in patch 4 to here and alter patch3 slightly.
That means patch4 gets dropped. I can do this and alter the commit
messages appropriately.

Hi John,
I'm seeing clang warnings after applying patches.
Clang is complaining about this line:
- if (STREQ(name, "lxc.network.type")) {
+ if (STREQ(name, "type")) {
virDomainDefPtr def = parseData->def;
I think it is irrelevant because there is no way to get a NULL pointer
from case structure.
During my tests, I'm being redirected to "Unhandled network property".
Technically, only lxcNetworkParseDataSuffix is using this method.
Btw, here is a possible fix for that...

Hmm.. I don't typically compile with clang, although I know there are a
few on the team that do and they haven't posted anything yet. I did see
on the #virt channel that travis-ci's bot complained:
https://travis-ci.org/libvirt/libvirt/builds/498459437
However, in looking at the output, it wasn't a compilation failure,
rather it was a failure to 'mv mr.gmo-t mr.gmo' it seems which would be
unrelated.
I also just installed clang 7.0.1, ran CC=clang sh autogen.sh, and then
did a build, but didn't see any failure.
If anything - I would think a well placed sa_assert(suffix) in
lxcNetworkParseDataEntry would assert to the compiler that suffix isn't
NULL. Of course the fact that lxcNetworkParseDataIPs got called means
that virLXCNetworkConfigEntryTypeFromString had a valid string. So,
perhaps it's an older clang compiler that's issuing the message.

New subject: [libvirt] [PATCH 6/6] lxc: Converting 'if, else' logic into a 'switch, case'.
On 2/18/19 2:09 PM, Julio Faracco wrote:
The structure used to handle network entries was based on
'if,else'
conditions. This commit converts this ugly structure into a switch to
clearify each option of the handler.

@entry was another option, but @elem I think is better than @type since
"type" is a field.
