[libvirt] [PATCH] Remove phyp driver
The phyp driver was added in 2009 and does not appear to have had any real feature change since 2011. There's virtually no evidence online of users actually using it. IMO it's time to kill it. Signed-off-by: Cole Robinson <crobinso@redhat.com> --- I raised this in 3.5 years ago: https://www.redhat.com/archives/libvir-list/2016-April/msg01060.html Not much on phyp/ side has changed since then, except dozens of dev patches transitioning the code forward. That mail also mentions xenapi and hyperv. hyperv saw signs of life afterwards and is still around. xenapi has been removed, along with uml. Considering the amount of code transitions we are currently undergoing (gnulib, glib, memory auto cleanup, etc), phyp/ will probably have an uptick of dev energy in the medium term. Let's bite the bullet and remove it! docs/aclpolkit.html.in | 4 - docs/api.html.in | 2 +- docs/drivers.html.in | 1 - docs/drvphyp.html.in | 50 - docs/schemas/capability.rng | 3 +- docs/schemas/domaincommon.rng | 2 +- libvirt.spec.in | 11 +- m4/virt-driver-phyp.m4 | 48 - mingw-libvirt.spec.in | 7 - po/POTFILES.in | 1 - src/Makefile.am | 1 - src/README | 1 - src/libvirt.c | 10 - src/phyp/Makefile.inc.am | 21 - src/phyp/phyp_driver.c | 3739 --------------------------------- src/phyp/phyp_driver.h | 24 - 16 files changed, 4 insertions(+), 3921 deletions(-) delete mode 100644 docs/drvphyp.html.in delete mode 100644 m4/virt-driver-phyp.m4 delete mode 100644 src/phyp/Makefile.inc.am delete mode 100644 src/phyp/phyp_driver.c delete mode 100644 src/phyp/phyp_driver.h diff --git a/docs/aclpolkit.html.in b/docs/aclpolkit.html.in index 4a8877d5e7..04cb39006a 100644 --- a/docs/aclpolkit.html.in +++ b/docs/aclpolkit.html.in @@ -365,10 +365,6 @@ <td>openvz</td> <td>OPENVZ</td> </tr> - <tr> - <td>phyp</td> - <td>PHYP</td> - </tr> <tr> <td>qemu</td> <td>QEMU</td> diff --git a/docs/api.html.in b/docs/api.html.in index 288b9ecf88..85b196417a 100644 --- a/docs/api.html.in +++ b/docs/api.html.in @@ -330,7 +330,7 @@ daemon through the <a href="remote.html">remote</a> driver via an <a href="internals/rpc.html">RPC</a>.

Not much on phyp/ side has changed since then, except dozens of dev patches transitioning the code forward.
That mail also mentions xenapi and hyperv. hyperv saw signs of life afterwards and is still around. xenapi has been removed, along with uml.
Considering the amount of code transitions we are currently undergoing (gnulib, glib, memory auto cleanup, etc), phyp/ will probably have an uptick of dev energy in the medium term. Let's bite the bullet and remove it!
With this squashed in too, forgot about 'grep -i' Maybe the auth.html.in bit can be entirely removed, I need to study how that works - Cole

I understand that this was a feature pushed by IBM years ago. I can't say about the primary author, but as far as current IBM stance goes, +1 for the removal. My suggestion would be to put the RFC link in the commit message of this patch, for reference. Thanks, DHB

I understand that this was a feature pushed by IBM years ago. I can't say about the primary author, but as far as current IBM stance goes, +1 for the removal.
My suggestion would be to put the RFC link in the commit message of this patch, for reference.
Thanks. I will amend the commit message to point to that thread, and this thread, if it's fully ACK'd. I'll wait for danpb's approval though Thanks, Cole

Not much on phyp/ side has changed since then, except dozens of dev patches transitioning the code forward.
That mail also mentions xenapi and hyperv. hyperv saw signs of life afterwards and is still around. xenapi has been removed, along with uml.
Considering the amount of code transitions we are currently undergoing (gnulib, glib, memory auto cleanup, etc), phyp/ will probably have an uptick of dev energy in the medium term. Let's bite the bullet and remove it!

I was super sure I had replied this before, but looks like I didn't :) I'm not really aware of the usage of this code. I guess it's not being used at all nowadays? I really can't tell. But if you're waiting for my ACK to drop all this: ACK
