* NetBSD build fixes for release-3.5Emmanuel Dreyfus2014-06-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 1) Make sure __THROW is definedThis is a backport of I6e7cb1eb59b84988e155e9a8b696e842b7ff8f7f 2) include <rpc/xdr.h> before <rpc/auth.h> so that XDR is defined This was fixed in master within I20193d3f8904388e47344e523b3787dbeab044acbut weonly pull up 3) NetBSD's gettext is in libintl, hence search it at configure time This is a backport of I651a74fe49c3f087fe135dab3453fd5b18b4268a 4) include <sys/wait.h> to have WEXITSTATUS defined This problem does not exist in master as WEXITSTATUS is not used 5) Do not define popcountl() on NetBSD as it is in <strings.h> This is a backport of I4428a88b1e0d7c5f6740022861ffe230dbbd84bd BUG: 764655 Change-Id: Ieea5a2a627e2b7930525d6c525f1602073574a97 Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-on: http://review.gluster.org/7925 Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>

* features/qemu-block: simplify coroutine model to use single synctask, ucontextBrian Foster2013-11-102-1/+225
| | | | | | | | | | | | | | | | | | | | | | | | The current coroutine model, mapping synctasks 1-1 with qemu internal Coroutines, has some unresolved raciness issues. This problem usually manifests as lifecycle mismatches between top-level (gluster created) synctasks and the subsequently created internal coroutines from that context. Qemu's internal queueing (and locking) can cause situations where the top-level synctask is destroyed before the internal scheduler has released references to memory, leading to use after free crashes and asserts. Simplify the coroutine model to use a single synctask as a coroutine processor and rely on the existing native ucontext coroutine implementation. The syncenv thread is donated to qemu and ensures a single top-level coroutine is processed at a time. Qemu now has complete control over coroutine scheduling.

* contrib/qemu: disable coroutine caching in qemuBrian Foster2013-10-091-1/+1
| | | | | | | | | | | | | | | Coroutine caching in qemu is dangerous in the manner that the qemu-block translator embeds the qemu block subsystem code. After a graph switch, new requests can fork off and pass active graph data structures (i.e., inodes) down into old syncenvs and old graphs, leading to failures.

* features/qemu-block: support for QCOW2 and QED formatsAnand Avati2013-09-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for internals snapshots using QCOW2 and general framework for external snapshots (next patch) with QCOW2 and QED. For internal snapshots, the file must be "initialized" or "formatted" into QCOW2 format, and specify a file size. Snapshots can be created, deleted, and applied ("goto"). e.g: // Format and Initialize sh# setfattr -n trusted.glusterfs.block-format -v qcow2:10GB /mnt/imgfile sh# ls -l /mnt/imgfile -rw-r--r-- 1 root root 10G Jul 18 21:20 imgfile // Create a snapshot sh# setfattr -n trusted.glusterfs.block-snapshot-create -v name1 imgfile // Apply a snapshot sh# setfattr -n trusted.gluterfs.block-snapshot-goto -v name1 imgfile Change-Id: If993e057a9455967ba3fa9dcabb7f74b8b2cf4c3 BUG: 986775 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/5367 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
