In #504 list_processes() got reworked in a way to avoid parsing process
output as this had interesting side-effects.
Back then I mentioned the same behaviour existing in slam_tomb() which
should probably be changed too. This PR addresses that.
Firstly it will use list_processes() from within slam_tomb(), as this is
in principal overlapping functionality. For this list_processes() needed
to be adjusted. It now has a return value which can indicate if there
were processes.
Secondly the order of execution was changed in slam_tomb(). Before it
would process one process and work through the signals until this
process was killed. Now it will take a signal and issue a kill for all
processes found.
new minimum increase for resize is 120MiB
increase resize delta on all test to be above new minimum
skip resize test for btrfs mixedmode (always fails)
it may happen, that someone bind mounts manually or via an immutable setup the tomb mountdir somewhere else.
Tomb should be able to discover such mounts and close them if the tomb itself is closed.
As the argument for list_tomb_mounts uses the input directly, it needs to be uniform.
Therefore one must make sure that extraneous character like parentheses are removed from the variable.
And those are in place in tombname for slam_tomb().
Instead of only looking for bind mounts from within a tomb due to bind-hooks, also consider bind mounts that happenfrom the outside (example: open a tomb and manually issue a mount --bind /media/tomb some/other/location).
Such a mount wouldn't be filtered before (only looking for an additional [/path/] added to TARGET.
Instead look for every mount that is related to the respective /dev/mapper/ entry of a tomb and also close or list them.
This helps to avoid to loop again against mounted tombs inside the main loop which loops over mounted tombs.
similar to list_tomb_mounts, rework the findmnt usage to usage of the
actual tomb mapper device.
Simplifies the awk usage and just only one argument needed for the
mapper function.
previously it had dedicated cases for listing all tombs and a singular
one, which duplicated code.
The function got reworked, that it uses a different approach for
findmnt. Instead of filtering the general result, it now uses --source
on the tomb specific crypsetup mapper. Those are searched via general
globbing of the devices in /dev/mapper. This allows to combine the
previous separate cases.
Additionally remove the usage of _sudo for findmnt, as it is not
necessary.
Cryptsetup is since 1.3.0 capable of setting up a loop device if the
device argument is a file.
This has the additional benefit that those loop devices will get the
AUTOCLEAR flag (available with Linux 2.6.25). This means those loop
devices will be closed as soon they're unused (on luksClose).
Somehow this section existed two times in the man page with similar information.
Enhance it with notes regarding wayland and adjust the recommened pinentry programs.
GTK2 is long time EOL and actively being fased out by distributions, which makes pinentry-gtk2 obsolete.
pinentry-tty will work on every headless system or from a textual interface. pinentry-curses may end up starting if the respective ncurses is available.
move contents one folder up. Instead of extras/tomber/tomber it now resides in extras/tomber.
Move and rename extras/PYTHON.md into extras/tomber/README.md, as it is the README of the tool.
Swish is outdated and recoll works much better as a frontend to
xapian, so we adopt it to provide local search over file contents in a
tomb. This update also makes plocate optional to search over file
names, not mandatory. Recoll works also in GUI using its -c
commandline option followed by the indexed tomb's path.
Parsing the output from lsof had possibilities for race conditions.
Either due to short lived processes or issuing "tomb ps" from a terminal which cwd is from inside the tomb.
This would spit out available users on the system.
To avoid this use the lsof output directly.
In the future formatting could be reintroduced via commands like
"lsof +D "$tombmount" -F Lc" or "lsof +D "$tombmount" -F Lc0".
This fixes#503
