Axel Burri ec037952cf btrbk: add "compat" config option (busybox: add test -d command) 
Add compat, compat_local, compat_remote configuration options.

Used for busybox: instead of running `readlink -e` (which is not
available on busybox), run `readlink -f` followed by `test -d`.

Axel Burri 52a823bb93 btrbk: rename context "root" to "global" 
Use same naming as in documentation: btrbk.conf.5

Axel Burri c11ab1507d btrbk: sanitize url on PRINT 
For consistency with PATH and URL, $vol->{PRINT} was not sanitized
(trailing "//" if parent is "/"). This is now dropped, as this is more
confusing than useful.

Axel Burri 936f88a68f btrbk: action ls: support url argument; fix duplicates / sorting 2020-05-24 02:48:00 +02:00
Axel Burri 30edf5b766 btrbk: action ls: fix match on child subvols of "/" 
If PATH contains double slash (intentional behavior of vinfo_child),
the match on root_path fails. Fixed by removing "//" from path.

Axel Burri 0c77219a62 documentation: README.md: fix backup restore example 
Especially dont recommend deleting the transferred subvolume, this
would break incremental chain for subsequent backups.

Axel Burri 1b533f2340 documentation: README.md: add instructions for downloading latest master 2020-01-02 17:59:20 +01:00
Axel Burri c03e960d90 ssh_filter_btrbk.sh: exclude "btrfs subvolume show|list" from restrict-path 
btrbk requires "btrfs subvolume list|show" queries from the mount
point in order to build btrfs trees. This conflicts with tightly set
--restrict-path.

Axel Burri 631a4c30fe btrbk: fix @stderr propagation from vinfo_init_root 
As we print @stderr in warnings if vinfo_init_root() function fails,
we need to make sure that @stderr contains sane values.

Clearing @stderr is required when calling caching functions!

Axel Burri 1f7773dddc btrbk: try readlink only once per url 
Change semantics of %realpath_cache: if "" (empty string), do not try
to run readlink shell command again on same URL.

Axel Burri 8c11c2eb7d btrbk: run_cmd: fix regression: dont print ssh errors 
Explicitely printing ssh errors (or even warnings) is
inconsistent. stderr is printed outside the run_cmd framework if
needed.

reverts a80e05984a btrbk: catch ssh errors

See ssh(1):

    ssh exits with the exit status of the remote command or with 255
    if an error occurred.

Note that this includes network errors as well as dns failures

Axel Burri 37b30caeb2 btrbk: bugfix: vinfo_match: skip match against invalid paths 
Dont check url_regex if $vinfo->{URL} is not a valid path (e.g. when
checking against a "volume" or "subvolume" having wildcards):

    "Use of uninitialized value in join or string" at line 3030

asymmetric 3694a38670 documentation: README.md: replace pv with mbuffer 
Since 0.29, mbuffer is used instead of pv.

Ryan Young 0f21df15c2 ssh_filter_btrbk.sh: whitelist mkdir for 'btrbk archive' operations 2019-10-27 12:24:00 +01:00
Asbjørn Apeland 2d7f5ec5fe contrib: systemd: btrbk.timer: change install target 
Using `WantedBy=multi-user.target` makes boot wait for btrbk.service
before it's considered "finished". This can be checked by running
`systemd-analyze` or checking the system log using `journalctl`.

Timers should use the "timers.target" target, see systemd.special(7).

Axel Burri 8551a9f52a btrbk: consistently use "subvolume" (instead of "subvol") for table headings 2019-09-08 18:23:30 +02:00
Axel Burri 5e87e8248b btrbk: add --pretty option: print lowercase column headings with separator line 2019-09-08 18:23:30 +02:00
Axel Burri 4629d5ae11 btrbk: change table output format: remove separator line, uppercase column headings 
Print table output column headings single-line uppercase instead of
lowercase and underlined.

This is common ascii table format, is easy parseable and offers better
readability e.g. in pager.

Axel Burri 485bc3ab0c btrbk: use global stderr (replace err); refeactor filter_stderr, add fatal_stderr 
if fatal_stderr is set and returns true, the command exit code is set
to -1, resulting in run_cmd() returning undef.

Axel Burri 360c8918bb btrbk: catch verbose errors from readlink 
readlink -v enables "report error messages", printing useful errors
like:

    readlink: /some/dir/: Permission denied
    readlink: /some/dir/: No such file or directory
