* btrfs-progs: tests: add testing image for zstd for btrfs-restoreNick Terrell2017-09-25
| | | | | | | | | | | Adds tests for the new features based on a prebuilt btrfs image with a zstd compressed file. Split from the previous patch. Signed-off-by: Nick Terrell <terrelln@fb.com> [ with some cleanups ] Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: Add zstd supportNick Terrell2017-09-25
| | | | | | | | | | | | | | | | Adds zstd support to the btrfs program. An optional dependency on libzstd >= 1.0.0 is added. Autoconf accepts `--enable-zstd' or `--disable-zstd' and defaults to detecting if libzstd is present using `pkg-config'. The patch is also available in my fork of btrfs-progs [1], which passes Travis-CI with the new tests. The prebuilt binary is available there. I haven't updated Android.mk.

* btrfs-progs: update btrfs-completionMisono, Tomohiro2017-09-25
| | | | | | | | | | | | This patch updates btrfs-completion: - add "filesystem du" and "rescure zero-log" - restrict _btrfs_mnts to show btrfs type only - add more completion in last case statements (This file contains both spaces/tabs and may need cleanup.)

* btrfs-progs: test: fix name generation not to contain trailing spacesMisono, Tomohiro2017-09-08
| | | | | | | | | | | | | First patch causes test-convert fails. This is because generate_dataset() creates a name containing trailing spaces for "slow_symlink" type, and cause getfacl error in convert_test_perm(). (This is not noticed since original run_check_stdout() throws away the error.) Fix this by use space for delimiter for cut.

* btrfs-progs: test: fix run_check_stdout() call _fail()Misono, Tomohiro2017-09-08
| | | | | | | | | | run_check_stdout() uses "... | tee ... || _fail". However, since tee won't fail, _fail() is not called even if first command fails. Fix this by checking PIPESTATUS in the end.

* btrfs-progs: inspect rootid: Allow a file to be specifiedMisono, Tomohiro2017-09-08
| | | | | | | | | | | | | Since cmd_inspect_rootid() calls btrfs_open_dir(), it rejects a file to be specified. But as the document says, a file should be supported. This patch introduces btrfs_open_file_or_dir(), which is a counterpart of btrfs_open_dir(), to safely check and open btrfs file or directory. The original btrfs_open_dir() content is moved to btrfs_open() and shared by both function.
