/* This is the API version, NOT package version */
build: Start using library versioning for various libraries According to libtool three individual numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The libtool script typically tacks these three numbers onto the end of the name of the .so file it creates. The formula for calculating the file numbers on Linux and Solaris is /path/to/library/<library_name>.(C - A).(A).(R) As you release new versions of your library, you will update the library's C:R:A. Although the rules for changing these version numbers can quickly become confusing, a few simple tips should help keep you on track. The libtool documentation goes into greater depth. In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number. This is called your interface number. The main use of this interface number is to tag successive revisions of your API. The AGE number is how many consecutive versions of the API the current implementation supports. Thus if the CURRENT library API is the sixth published version of the interface and it is also binary compatible with the fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When you break binary compatibility, you need to set AGE to 0 and of course increment CURRENT. The REVISION marks a change in the source code of the library that doesn't affect the interface-for example, a minor bug fix. Anytime you increment CURRENT, you should set REVISION back to 0.

copy_file_range support in GlusterFS * libglusterfs changes to add new fop * Fuse changes: - Changes in fuse bridge xlator to receive and send responses * posix changes to perform the op on the backend filesystem * protocol and rpc changes for sending and receiving the fop * gfapi changes for performing the fop * tools: glfs-copy-file-range tool for testing copy_file_range fop - Although, copy_file_range support has been added to the upstream fuse kernel module, no release has been made yet of a kernel which contains the support. It is expected to come in the upcoming release of linux-4.20 So, as of now, executing copy_file_range fop on a fused based filesystem results in fuse kernel module sending read on the source fd and write on the destination fd. Therefore a small gfapi based tool has been written to be able test the copy_file_range fop. This tool is similar (in functionality) to the example program given in copy_file_range man page. So, running regular copy_file_range on a fuse mount point and running gfapi based glfs-copy-file-range tool gives some idea about how fast, the copy_file_range (or reflink) can be. On the local machine this was the result obtained. mount -t glusterfs workstation:new /mnt/glusterfs [root@workstation ~]# cd /mnt/glusterfs/ [root@workstation glusterfs]# ls file [root@workstation glusterfs]# cd [root@workstation ~]# time /tmp/a.out /mnt/glusterfs/file /mnt/glusterfs/new real 0m6.495s user 0m0.000s sys 0m1.439s [root@workstation ~]# time glfs-copy-file-range $(hostname) new /tmp/glfs.log /file /rrr OPEN_SRC: opening /file is success OPEN_DST: opening /rrr is success FSTAT_SRC: fstat on /rrr is success copy_file_range successful real 0m0.309s user 0m0.039s sys 0m0.017s This tool needs following arguments 1) hostname 2) volume name 3) log file path 4) source file path (relative to the gluster volume root) 5) destination file path (relative to the gluster volume root) "glfs-copy-file-range <hostname> <volume> <log file path> <source> <destination>" - Added a testcase as well to run glfs-copy-file-range tool * io-stats changes to capture the fop for profiling * NOTE: - Added conditional check to see whether the copy_file_range syscall is available or not. If not, then return ENOSYS. - Added conditional check for kernel minor version in fuse_kernel.h and fuse-bridge while referring to copy_file_range. And the kernel minor version is kept as it is. i.e. 24. Increment it in future when there is a kernel release which contains the support for copy_file_range fop in fuse kernel module. * The document which contains a writeup on this enhancement can be found at https://docs.google.com/document/d/1BSILbXr_knynNwxSyyu503JoTz5QFM_4suNIh2WwrSc/edit Change-Id: I280069c814dd21ce6ec3be00a884fc24ab692367 updates: #536 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com>
