v5: Address review comments from Peter on v4 Dropping Patch 3 from v3 Patch 1: fix transport type in all drivers, possible switch case converts Patch 2: use virObject with src->drv to avoid 'initFlag' for remembering 'virStorageFileInit' status Patch 3: * change virStorageBackendGlusterCacheQuery to *Lookup * change virStorageBackendGlusterCacheRefresh to *Release * Avoid the global Flags * Thread safe measure by using virCond* Thanks Peter! v4: Address review comments from Peter on v3 Patch 1: changes to fix test failures (qemuargv2xmltest, qemuxml2argvtest, qemuxml2xmltest and virstoragetest) Patch 2: fix hung in qemuxml2argvtest Patch 3 v3: Split this Patch to 2 parts as below Patch 3 v4: don't free metadata used for storage driver access Patch 4: * update variable naming as per standards * virStorageBackendGlusterPreopened* -> virStorageBackendGlusterCache* Thanks Peter! v3: Address comments by Daniel and Peter on v2 * Split the patch to 3 parts Patch 1: change the virStorageNetHostDef type Patch 2: optimize calls to virStorageFileInit and friends Patch 3: add the caching for glfs * Thanks to Daniel, this version make all the methods as thread safe * Thanks to Peter for pointing use of virObjectLockable, this had simplified rest of the parts a lot. v2: Address review comments from Peter on v1 * Rebased on latest master * Changes to commit msg * Introduce storage API's for Register and Unregister of volume * During qemu process Start/Stop and snapshot create * Check Transport and Port type * Atomic element add/del to list and ref counting Pending: Treating IP and FQDN belong to same host v1: Initial patch Prasanna Kumar Kalever (3): util: change the virStorageNetHostDef type storage: optimize calls to virStorageFileInit and friends gluster: cache glfs connection object per volume src/conf/domain_conf.c | 60 +++-- src/libxl/libxl_conf.c | 10 +- src/qemu/qemu_command.c | 97 ++++--- src/qemu/qemu_domain.c | 25 +- src/qemu/qemu_domain.h | 8 +- src/qemu/qemu_driver.c | 26 +- src/qemu/qemu_parse_command.c | 50 ++-- src/qemu/qemu_process.c | 49 ++++ src/qemu/qemu_process.h | 4 + src/storage/storage_backend.h | 1 + src/storage/storage_backend_fs.c | 5 + src/storage/storage_backend_gluster.c | 329 ++++++++++++++++++++--- src/storage/storage_driver.c | 40 ++- src/storage/storage_driver.h | 2 + src/util/virstoragefile.c | 93 ++++--- src/util/virstoragefile.h | 21 +- src/xenconfig/xen_xl.c | 10 +- tests/domainsnapshotxml2xmlin/disk_snapshot.xml | 2 +- tests/domainsnapshotxml2xmlout/disk_snapshot.xml | 2 +- tests/virstoragetest.c | 2 +- 20 files changed, 614 insertions(+), 222 deletions(-) -- 2.7.4
