| * block: use fdatasync instead of fsync if possibleChristoph Hellwig2009-09-111-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are flushing the caches for our image files we only care about the data (including the metadata required for accessing it) but not things like timestamp updates. So try to use fdatasync instead of fsync to implement the flush operations. Unfortunately many operating systems still do not support fdatasync, so we add a qemu_fdatasync wrapper that uses fdatasync if available as per the _POSIX_SYNCHRONIZED_IO feature macro or fsync otherwise.

| * Add bdrv_aio_multiwriteKevin Wolf2009-09-111-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One performance problem of qcow2 during the initial image growth are sequential writes that are not cluster aligned. In this case, when a first requests requires to allocate a new cluster but writes only to the first couple of sectors in that cluster, the rest of the cluster is zeroed - just to be overwritten by the following second request that fills up the cluster. Let's try to merge sequential write requests to the same cluster, so we can avoid to write the zero padding to the disk in the first place. As a nice side effect, also other formats take advantage of dealing with less and larger requests. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

| * support colon in filenamesRam Pai2009-06-291-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: It is impossible to feed filenames with the character colon because qemu interprets such names as a protocol. For example filename scsi:0, is interpreted as a protocol by name "scsi". This patch allows user to espace colon characters. For example the above filename can now be expressed either as 'scsi\:0' or as file:scsi:0 anything following the "file:" tag is interpreted verbatin. However if "file:" tag is omitted then any colon characters in the string must be escaped using backslash. Here are couple of examples: scsi\:0\:abc is a local file scsi:0:abc http\://myweb is a local file by name http://myweb file:scsi:0:abc is a local file scsi:0:abc file:http://myweb is a local file by name http://myweb Signed-off-by: Ram Pai <linuxram@us.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
