Change in vdsm[master]: Unify produceVolume
by deepakcs＠linux.vnet.ibm.com 13 Jan '13

13 Jan '13

Deepak C Shetty has uploaded a new change for review. Change subject: Unify produceVolume ...................................................................... Unify produceVolume Unify produceVolume function and make it use getVolumeClass so that subclasses can override getVolumeClass to specify their own Volume and ensure that produceVolume works properly with subclass supplying their own volumeclass.

Change in vdsm[master]: Introduce getMountPoint for NfsStorageDomain

Deepak C Shetty has uploaded a new change for review. Change subject: Introduce getMountPoint for NfsStorageDomain ...................................................................... Introduce getMountPoint for NfsStorageDomain Move the code to generate the mount point into a seperate function, so that classes reusing NfsStorageDomain can override the function to present their own mount point path.

Change in vdsm[master]: [WIP] vdsm API and libvdsm
by agl＠us.ibm.com 11 Jan '13

11 Jan '13

Adam Litke has uploaded a new change for review. Change subject: [WIP] vdsm API and libvdsm ...................................................................... [WIP] vdsm API and libvdsm In this release you can actually execute real API calls against a remote server. See the test programs for examples in C and Python. Known issues: - Unions are untested and probably broken - Optional value parameters (int, bool, enum, etc) do not work from python - Incorrect GIR generation for functions returning arrays (see gir-fixes.patch) - Need to convert parameters/return values in Bridge when the schema types differ from the internal types (ie. IntStr) Changes since V1: - API is generated for the full schema - Server-side support - RPM packaging (vdsm-jsonrpc (for server) and vdsm-api (for client)) This work-in-progress patch demonstrates the mechanics of generating a working C API and remote transport from a schema definition. The "C" API is written in Vala to more easily take advantage of GObjects and reduce the amount of boilerplate code that we need to generate and maintain. The API has a static part and a dynamically generated part. I generate the dynamic part by using the same technique employed by qemu for generating the qapi bindings (python format strings). The build system produces libvdsm and a C test program. An included python program demonstrates how the automatic python bindings work. A test server is included to enable the test programs to function. We use JSON for internal object storage and also as the wire format. Thank you Saggi for sharing some great ideas (many of which are incorporated into this patch). TODO: - Fix issues in the main schema * Return values must be anonymous, singular types * Remove 'IntStr' and friends in favor of native representation - Support generation for the entire schema * Mapping types * Enums with non-C string values * Finish array support * Generate the command sub-classes (VM, Volume, StorageDomain, etc) - Connect the server to the real vdsm API * Functions must map from the new schema to the old implementation - Validate argument and return types on the server side - Probably a few more things I haven't yet thought of Signed-off-by: Adam Litke <agl(a)us.ibm.com> Change-Id: If6bd34700b86aa84c7e289f02c0e9f2ac6fcba63 --- M Makefile.am M build-aux/gitlog-to-changelog M configure.ac M vdsm.spec.in M vdsm/clientIF.py M vdsm/config.py.in A vdsm_api/BindingJsonRpc.py A vdsm_api/Bridge.py A vdsm_api/Makefile.am A vdsm_api/generate.py A vdsm_api/gir-fixes.patch A vdsm_api/libvdsm-base.vala A vdsm_api/schema.json A vdsm_api/test.c A vdsm_api/test.py A vdsm_api/test_serv.py M vdsm_api/vdsmapi-schema.json 17 files changed, 4,308 insertions(+), 59 deletions(-) git pull ssh://gerrit.ovirt.org:29418/vdsm refs/changes/16/7516/1 diff --git a/Makefile.am b/Makefile.am index 17b5a85..d52964b 100644 --- a/Makefile.am +++ b/Makefile.am @@ -18,10 +18,12 @@ # Refer to the README and COPYING files for full details of the license # -SUBDIRS = vdsm vdsm_cli vds_bootstrap vdsm_reg vdsm_hooks tests vdsm-tool +SUBDIRS = vdsm vdsm_cli vds_bootstrap vdsm_reg vdsm_hooks tests vdsm-tool vdsm_api include $(top_srcdir)/build-aux/Makefile.subs +ACLOCAL_AMFLAGS = -I m4 + # This is an *exception*, we ship also vdsm.spec so it's possible to build the # rpm from the tarball.
