Since our test environment runs also in non-real-udev world,
it's using /etc/.cache file with scanned files.
So in this case it is mandatory the user runs 'vgscan'
after a device reappears in the system.
This 'first' lvm2 command then fixes metadata (just like vgs did).
With thin-pool kernel target module 1.13 it's now support usage of
external origin with sizes which are not 'alligned' with chunk size
of thin-pool.
Enable lvm2 support for this and also fix reporting of data_percent
usage for case sizes are not alligned.
More exact clean of library exported symbols files.
Also use $(firstword) test to check for empty string
so 'make clean' has now cleaner condensed look.
Clean also created include links.
Set LVM_TEST_THIN_REPAIR_CMD to /bin/false for test which
doesn't need it.
This way - even if on the system there is no such tool present,
test will not result with warning about missing tool.
Also remove from Makefile settings of TEST vars which are set in
through /lib/paths - this also allows to override them in test.
Since now we enable those by default when compiled with those daemons,
explicitely disable them in tests when needed.
Alphabetically sort configurables.
Use 64bit arithmentic for PV size calculation (Coverity).
Also remove sector shift for compared PV size, since all
values are already held in sectors.
This fixes validatio of PV size when restoring PV
from vg metadata backup file.
Improve the python unit test case to cover all of the properties of a LV and
the properties of a LV segment.
In addition we also add a 'tag' to the lv so that we can retrieve it
using the 'lv_tags' property to ensure that this works as expected.

Introduce LVM_TEST_LVMETAD_DEBUG_OPTS to allow to override
default debug opts for lvmetad.
However could be still overloaded on command line:
make check_lvmetad LVM_TEST_LVMETAD_DEBUG_OPTS="-l all"...
Better name for aux function.
First use normal -TERM, and only after a while use -KILL
(leaving some time to correctly finish)
Print INFO about killed processes.
New lvmconf function is using bash associative arrays - however
older systems like RHEL5 doesn't provide this feature. In this case
stay with older variant.
Restore support for use case like this:
aux lvmconf 'tags/@foo {}'
some tests left dangling bg processes originating in
lvm2 commands being able to spawn any bg polling process
(lvchange, vgchange, pvmove, lvconvert...)
Initial fn 'add_to_kill_list' should collect processes with
specific parameters (proc's command line and parent processes ID).
After testing finishes the fn kill_listed_processes should remove these
listed by 'add_to_kill_list'.
Unfortunately it proved to be prone to an error especially in scenarios
where cmd line of initiating command contained characters required to
be espaced before passing to shell script to make it work correctly.
(Or if cmd spawned more than one bg process with same cmd line. i.e.:
vgchange or lvchange).
The new implementation is much simpler. It uses env. variable (LVM_TEST_TAG)
for marking a process desired to be killed later or during test env. teardown.
(i.e.: LVM_TEST_TAG=kill_me_$PREFIX to kill only processes related to
current test environment)
When test is executed on real device - lets try a more complete
cleanup - discard whole device first and try to wipe any
headers it might be left from previous test.
When test suite is used from installed rpm package
we need to handle things better.
This patch is rather first approach - expecting few more
tweaks needed.
At this moment LVM_LOG_FILE_EPOCH with
LVM_EXPECTED_EXIT_STATUS properly deletes debug logs
only for real commands - support for lvm2 API does not yet
exists
Enhance 'not' to manage autodeletion of log files in right cases.
Use separately marked epoch log files for clvmd and dmeventd.
Properly manage stack tracing for new debug.log names.
Previous commit has made have_cache & have_thin producing
false return value.
Fix it and at the some time provide much better reconfiguring
warning message.
If the test machine is missing needed and configured binaries
it will produce TEST WARNING result.
When a var like LVM_TEST_THIN_CHECK_CMD is set to ""
(which is valid) we need to correctly use '-'.
Otherwise ':-' replaces such value with built-in default.
Put in pvmove background process into list quickly.
Update API for aux add_to_kill_list()/kill_listed_processes().
Run on 'background' (&) only non-background pvmoves.
If the system is correctly configure (cache & thin tools are present)
avoid 'extra' rebuild of configuration.
On the other hand - if some tool is missing - duplicate ##LVMCONF should
make it more straighforward to see.
Reenable TESTDIR & PREFIX replacement.
Since we need to replace string in proper order (1st. @TESTDIR@,
2nd. @PREFIX@), drop map and use plain string.
Drop timestamp logging when 'stacktracing'
Added lvm_vg_write in the addTag/removeTag paths to make the
changes persist. Added unit test to ensure functionality.

When clvmd starts, it starts it's own command logging into debug.log.
This is interferring with our other command debug.log.
As as sideeffect we may experience log from command,
followed but lots of zeros and continued with clvmd log.
Fix it by renaming debug.log and now we could also print this trace
to get full list of clvmd activity nicely.
Also improve some post-mortem prints from udevadm and dmsetup to
make the output more usable.
Since now we have metadata parts running with normal speed,
we could avoid reinitilising delayed dev for every test.
(Saving seconds on cookie waits...)
Use common code for error_dev & delay_dev.
Both functions now take list of sectors.
From now on we could delay just 'extent' section, while
keeping running lvm commands fast (having native metadata area).
We cannot print TEST WARNING within test shell script
(since it's running in debug mode and thus always prints it)
Use 'should false' trick let the string printed in this case.
So 'non cluster cases' should now end properly.
If the kernel has 'new lcm()' (3.19) it provides wrong
optimal_io_size value for dm device so lvm2 command cannot
create properly aligned devices.
Use 'should' for this case - so test ends with 'TEST WARNING'.
Improve testing for condition that pvmove0 is already running in the
table (so we do not kill pvmove while it has loaded target, but
it's not yet Live).
Also delay_dev for 200ms.
When we use /dev/loopX device - shift first PV1 sector by 1M
so /dev/loop0 and dm device do not appear as same device.
Also notify lvmetad once 'devs' are created - so in case this
command is called in the middle of test - lvmetad properly
drops its metadata for these devices.
Drop used test.img file between reuse so the 'prepare_vg'
always starts with zeroed disks.
When LVM_TEST_AUX_TRACE is set, allow shell tracing of aux commands.
There is no reason to support persistent major/minor numbers
for pool volumes - it's only meant to be supported for filesystems
(since i.e. nfs may need to keep volume on a persistent device node.)
Support for pools is now explicitely disabled and documented.
Metadata areas which are marked as ignored should not be scanned
and read during pvscan --cache. Otherwise, this can cause lvmetad
to cache out-of-date metadata in case other PVs with fresh metadata
are missing by chance.
Make this to work like in non-lvmetad case where the behaviour would
be the same as if the PV was orphan (in case we have no other PVs
with valid non-ignored metadata areas).
Simplify the function usage and clean up parameter parsing.
There were 2 significant changes made in the test itself
(they passed before because of incorrect shell string handling)
-pvs_sel 'tags="pv_tag1"' "$dev1 $dev2"
+sel pv 'tags="pv_tag1"' "$dev1" "$dev6"
-lvs_sel '(lv_name=vol1 || lv_name=vol2) || vg_tags=vg_tag1' "vol1 vol2
abc orig snap"
+sel lv '(lv_name=vol1 || lv_name=vol2) || vg_tags=vg_tag1' vol1 vol2
orig snap xyz
Avoid busy-looping on CPU while reading socket pipe
and always call read only when select tells there is
something for read.
Change the batch output to old nicer output.
The string reported by uname -n may include characters
that lvm omits from the system id (like parens, as seen
on a test machine.) Check against the final system id
string that lvm uses.
Though vgremove operates per VG by definition, internally, it
actually means iterating over each LV it contains to do the
remove.
So we need to direct selection a bit in this case so that the
selection is done per-VG, not per-LV.
That means, use processing handle with void_handle.internal_report_for_select=0
for the process_each_lv_in_vg that is called later in vgremove_single fn.
We need to disable internal selection for process_each_lv_in_vg
here as selection is already done by process_each_vg which calls
vgremove_single. Otherwise selection would be done per-LV and not
per-VG as we intend!
An intra-release fix for commit 00744b053f.
pvchange now uses process_each_pv so uncomment parts of the test
which check proper functionality of intersection between selection
result and PVs or PV tags directly provided on command line. This
didn't work properly before when pvchange was not using process_each_pv.
For example:
pvchange -u -S 'pv_name=/dev/sda' /dev/sdb
..changes nothing since clearly the intersection of /dev/sda and
/dev/sdb is empty set. The same applies for tags:
pvchange -u -S 'pv_name=/dev/sda' @some_tag
..changes nothing if /dev/sda is not tagged with some_tag.
