For explanation why this is needed see 2/4. Patch 1/4 are test data split
out from 1/3 of the previous version to ease reviewing of 2/4.
Peter Krempa (4):
nodeinfo_test: Enhance test data before changing nodeinfo gathering
nodeinfo: Fix gathering of nodeinfo data structure
test: Add new test case for nodeinfotest
test: Add test case for nodeinfotest if host machine doesn't have

Okay, you got me. It took me a while to realize you are adding just

New subject: [libvirt] [PATCHv3 2/4] nodeinfo: Fix gathering of nodeinfo data structure
This patch changes the way data to fill the nodeinfo structure are
gathered. We've gathere the test data by iterating processors an sockets
separately from nodes. The reported data was based solely on information
about core id. Problems arise when eg cores in mulit-processor machines
don't have same id's on both processors or maybe one physical processor
contains more NUMA nodes.
This patch changes the approach how we detect processors and nodes. Now
we start at enumerating nodes and for each node processors, sockets and
threads are enumerated separately. This approach provides acurate data
that comply to docs about the nodeinfo structure. This also enables to
get rid of hacks: see commits 10d9038b744a69c8d4bd29c2e8c012a097481586,
ac9dd4a676f21b5e3ca6dbe0526f2a6709072beb. (Those changes in nodeinfo.c
are efectively reverted by this patch).
This patch also changes output of one of the tests, as the processor
topology is now acquired more precisely.

Otherwise looking good. ACK with switching to reentrant readdir, errno
setting before first usage and comment indentation fixed.

I guess we want reentrant version of readdir here, don't we?
readdir_r() is a GNU extension not provided by gnulib, so we can't use
it. Furthermore, readdir() is thread-safe if you have only one thread
traversing a given DIR*; readdir_r() is only useful if you want to have
multiple threads visit the same DIR* (which is not what we are doing
here). For that reason, our syntax check does not forbid readdir, and
we don't need to use readdir_r.

You should have reset errno before while() loop.
That part is true - you MUST reset errno before every call to readdir(),
as it is the only way to tell errors apart from end-of-iteration.

Again, s/readdir/readdir_r/
Overkill, not necessary.

New subject: [libvirt] [PATCHv3 3/4] test: Add new test case for nodeinfotest
This patch adds test data that describe a machine that has two physical
processors that don't share same core id's on their cores. On this data
the "virsh nodeinfo" reported that the machine had 10 cores per socket
while the processor had only 8. (Before fixing nodeinfo gathering code).

New subject: [libvirt] [PATCHv3 3/4] test: Add new test case for nodeinfotest
On 09.07.2012 17:17, Peter Krempa wrote:
This patch adds test data that describe a machine that has two
physical
processors that don't share same core id's on their cores. On this data
the "virsh nodeinfo" reported that the machine had 10 cores per socket
while the processor had only 8. (Before fixing nodeinfo gathering code).

Don't add empty newline here.
We have an explicit whitespace exemption for these sorts of files, so
that they can match actual machine outputs with their trailing empty
line. This particular file will not trigger either a syntax check error
or a commit hook rejection.
ACK modulo empty newline.
Empty newline is fine in this case, actually.

New subject: [libvirt] [PATCHv4 2/4] nodeinfo: Fix gathering of nodeinfo data structure
This patch changes the way data to fill the nodeinfo structure are
gathered. We've gathere the test data by iterating processors an sockets
separately from nodes. The reported data was based solely on information
about core id. Problems arise when eg cores in mulit-processor machines
don't have same id's on both processors or maybe one physical processor
contains more NUMA nodes.
This patch changes the approach how we detect processors and nodes. Now
we start at enumerating nodes and for each node processors, sockets and
threads are enumerated separately. This approach provides acurate data
that comply to docs about the nodeinfo structure. This also enables to
get rid of hacks: see commits 10d9038b744a69c8d4bd29c2e8c012a097481586,
ac9dd4a676f21b5e3ca6dbe0526f2a6709072beb. (Those changes in nodeinfo.c
are efectively reverted by this patch).
This patch also changes output of one of the tests, as the processor
topology is now acquired more precisely.
