Axel Burri 12f608d828 btrbk: fix regression: clear realpath cache on mkdir 
On btrbk archive, after creating a directory without dry-run, the
archive target is skipped with "Failed to fetch subvolume detail" due
to caching of realpath.

Regression in btrbk-0.32.0:

Axel Burri 795418ebe1 btrbk.conf.example: remove timestamp_format 
Now that timestamp_format defaults to "long", it seems no longer
needed to even mention it here. Setting to "short" or "long-iso" is
only required in rather special use cases.

Axel Burri 0172e4a240 btrbk: fix mountinfo tree root detection 
Set node as tree root if mount_id == parent_id. For some reasons this
is never the case on my (mostly gentoo) systems.

Axel Burri 8cc74fecc1 btrbk: default timestamp_format=long 
This is a relict of early days of btrbk, and I have already hesitated
for too long to change the default from legacy "short" to sane "long"
format.

Tests show that the scheduling behaves in a sane/expected way if this
change is applied unattended. I suppose everybody who has
preserve_hour_of_day set is already using timestamp_format=long.

Axel Burri ca166d47b6 btrbk: add safe_commands config option 
For the paranoid. For convenience, filename checking was removed in
[1], and quoting was (hopefully) implemented correctly in [2].

Allowing special characters as well as UTF8 leave behind a bad
feeling, as there are many special cases that needs to be taken care
of (e.g. newlines in file names, right-to-left encoding, etc.). In
order to mitigate attacks expoiting these error classes, leave an
option to power users which do only allow "sane" characters in their
filename hierarchy.

  [2] acc7f9fc83 btrbk: quote unsafe characters in shell commands

Axel Burri d7653a9e0a documentation: add incremental_prefs; adapt incremental_clones 2021-08-27 17:20:47 +02:00
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
