<title>core: make gf_thread_create() easier to use</title>

<id>4674678951a1315975d66016fb55c49100b7819f</id>
<content type='text'>
This patch creates a specific function to set the thread name using a
string format and a variable argument list, like printf().

This function is used to set the thread name from gf_thread_create(),
which now accepts a variable argument list to create the full name. It's
not necessary anymore to use a local array to build the name of the
thread. This is done automatically.

Problem: In changelog xlator after destroying listener it call's
         unlink to delete changelog socket file but socket file
         reference is not cleaned up from process memory

Solution: 1) To cleanup reference completely from process memory
             serialize transport cleanup for changelog and then
             unlink socket file
          2) Brick xlator will notify GF_EVENT_PARENT_DOWN to next
             xlator only after cleanup all xprts

Test: To test the same run below steps
      1) Setup some volume and enable brick mux
      2) kill anyone brick with gf_attach
      3) check changelog socket for specific to killed brick
         in lsof, it should cleanup completely

fixes: bz#1600145

<title>copy_file_range support in GlusterFS</title>

    * 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 &lt;hostname&gt; &lt;volume&gt; &lt;log file path&gt; &lt;source&gt; &lt;destination&gt;"

      - 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

<title>libglusterfs: Move devel headers under glusterfs directory</title>

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation &lt;&gt; in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

Some of the scripts that have a #!/usr/bin/python3 shebang do not have a
main() like function. These scripts will not get executed but only
imported. They do not need the shebang.

A few others are not installed with 'make install', but do have a main()
like function. These scripts are expected to be used by developers for
different tasks (mostly code generation). Marking these scripts
executable to make it easier to identify them.
