Christian Denk 6ff62cf2ba On branch sync-after-delete 
Your branch is up to date with 'origin/sync-after-delete'.

 Changes to be committed:
	modified:   btrbk
	modified:   ssh_filter_btrbk.sh

btrbk:
- included the btrbk filesystem sync command for btrfs-progs-sudo
- inserted the btrbk filesystem sync command in between btrfs subvolume delete and btrfs subvolume sync in case "btrfs_commit_delete=sync"

Rationale:
The btrfs filesystem sync actually triggers the deletion of the subvolume right away. Therefore, btrfs subvolume sync does not wait so long.

Axel Burri fe53198661 btrbk: drop support for deprecated raw format 
Raw backups created by btrbk < 0.26.0 are now ignored:

Axel Burri 85c2d14287 btrbk: change incremental_prefs defaults 
New defaults gives the btrbk_direct_leaf snapshots higher preference
than the global ones resolved by parent-uuid (which are best-guess).

This way the parent has a higher chance of being a backup created by
btrbk, which results in "btrfs receive" to start work on a snapshot of
this (and preferably not on the "best-guess" ones).

Axel Burri eb69bc883e btrbk: refactor mountinfo 
- Create tree from /proc/self/mountinfo, and use it to find mount
  points.

- Populate realpath cache from mount points, possibly reducing calls
  to `realpath`.

- Replace btrfs_mountpoint with vinfo_mountpoint(fs_type => 'btrfs)

- Tidy action "ls".

- Move code

Axel Burri 48bf4f05b9 btrbk: fix table output for utf8 characters (require Text::CharWidth) 
Use Text::CharWidth::mbswidth() if installed, fallback to
length(Encode::decode_utf8()), fallback to length().

 - Text::CharWidth handles wide chars (e.g. asian, taking up two
   columns on the terminal) correctly.

 - length(Encode::decode_utf8()) handles single-width chars only, and
   should be installed on most systems (perl >= v5.7.3).

 - langth() counts bytes, as we do not convert anything to UTF-8 in
   btrbk (NOT using `perl -CIOEioA` or binmode(STDOUT, ":utf8"))

Axel Burri acc7f9fc83 btrbk: quote unsafe characters in shell commands 
As filenames can contain meta characters like '$', we can't just put
ssh commands in double quotes. E.g. the following would trigger
variable expansion on local shell:

    ssh example.com "ls -l 'evil$x'"

Instead, we quote the ssh using single quotes (adding the need to
escape single quotes), while also quoting unsafe filenames using
single quotes. The above becomes:

    ssh example.com 'ls -l '\''evil$x'\'''

Or more complex, for a file named "file with'single quotes'":

    ssh example.com 'ls -l '\''file with'\''\'\'''\''single quotes'\''\'\'''\'''\'''

On the remote shell, this will expand to:

    ls -l 'file with'\''single quotes'\'''
