Axel Burri 4b7b7cfc06 documentation: btrbk.1: rephrase --format=raw 2021-08-18 02:08:28 +02:00
Axel Burri af5d25c5a9 btrbk-verify: expect single quotes from btrbk raw table output 2021-08-18 02:08:28 +02:00
Axel Burri 81a04e4287 btrbk: use single quotes for raw table format 2021-08-18 02:08:28 +02:00
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 2933e65cbe btrbk: adapt usage of unsafe arguments for run_cmd 2021-08-18 02:08:28 +02:00
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'\'''

Axel Burri d9958cbbc1 btrbk-verify: use new raw table format keys 2021-08-09 19:06:20 +02:00
Axel Burri 9278211123 btrbk: fix resolved ambiguity in raw table formats 
rename snapshot_path -> snapshot_subvolume
rename target_path   -> target_subvolume

These point to subvolumes, not paths containing subvolumes.

Axel Burri e257077241 btrbk: allow subvolume context without volume (add dummy section) 
Unfortunately the framework relies on "url" for the volume. This
should not be printed anywhere, using "/dev/null" should be fine.

Axel Burri d3d04f2252 btrbk: remove subvolume_path from schedule table 
This is the only format where SUBVOL_PATH is displayed. As SUBVOL_PATH
is only available for vinfo_child, this can not be used in global
scope.

Axel Burri ce9c21bd24 btrbk: tidy check for btrbk subvolume 
The original idea was probably to have a trace log for skipped
subvols.
