PAGE_SIZE is not a compile time constant. Use sysconf instead like
elsewhere in the code.

This minor patch fixes grammar in a few messages which get
printed to users. It also fixes the same grammar mistake in
several comments.

lib was using dev_test_excl which wasn't closing the device.
Switch code to new io layer with excl open.
Also use exclusive open in some other places.

Create bcache with one block per device that
will be scanned up to 1024 max blocks.

After recent changes this seems to give some help, explore more...

Find also python3 lvm.so name.
And ATM just run a single test, otherwise we get too many cores.

Properly check for kernel version.
Also detect sysfs throttling support.
|
| | | |
|
| | | |
|
| | |
| |
| |

Since python path is evaluated and we cannot use anymore /usr/bin/env
switch to generated file.

No point to start building lvm without this header file.
Although there could be 'some point' in supporting standalone build
of 'just' libdm where the libaio might be avoided.
TODO: think about configure option for building libdm only.

Matching patch 2eba7c77557655cfbd19f191ec5d1ad1025897b3

Needs to be changed to match 4K extent_size.

Unfortunatelly on kernels <4.16 lvm2 can't user brd ramdisks
for backend device as number of test is failing with this kernel
message:
device-mapper: ioctl: can't change device type after initial table load.
caused by DAX request-based handling, and lvm2 tries to replace device
with backend 'error' bio-based device and such table reload is being
rejected.
So ATM keep ramdisk only on most recent kernel to experiment a bit,
for older machines just stay safe and keep old slower loop backend.

valgrind was concerned about loop through vginfo->infos,
so grab info from dev.
|
| | |
| |
| |
| | |
some objects had been moved out of mem pools.
|
| | |
| |
| |
| |
| | |
When even throttling is not available, skip or use should
with particular test piece.

As mkostemp is only on newer systems, switch to more old version
which effectively does exactly the same thing for given list of
open flags.
|
| | |
| |
| |
| |
| |
| | |
While newer system can detect need for 4K mkfs, on older test machines
running test suite over 4k is reporting problems.
Some more generic solution is needed thought.

Forgotten revert of tracing patch. Restoring previous functinality.
|
| | |
| |
| |
| |
| | |
Replace previous compilation detection of present supported segtypes
with runtime check.
|
| | |
| |
| |
| | |
List also lcov for processed unit tests.
|
| | | |
|
| | |
| |
| |
| | |
Allow unit-test to be run as part of standard 'make check'.
|
| | |
| |
| |
| |
| |
| |
| |
| | |
When test happens to run in tmpfs, it cannot use O_DIRECT (unsupported
with tmpfs).
CHECKME: unsure if detection of tmpfs is 'valid' but kind of works and
is very simple.

As Makefiles already do use target with name 'device-mapper'
rename this new device-mapper dir to non-conflicting name.
We also seem to already use '_' in other dir names.
Also rename device_mapper/Makefile to source for generating Makefile.in
so we can use it for build in other source dirs properly.

It's very hard to use some 'non-recurive' Makefiles with
rest of system running 'recursively'.
So ATM drop inclusion of subdir makefile and add support
for 2 new top-level targets:
unit-test (builds test/unit dir)
run-unit-test (build & run test/unit/unit-test run)

Logging for libdm differs from lvm logging - keep using consisten
logging function calls.

Just like 52656c89fd6e7655b0599e20f90cc9d70561f1fb
when now cache is compiled in 'unditionally'.
This patch is actually enforce by changes in
commit: 2bc896f2a3a0023a4f45f10da3d0a22295a633ee
where CACHE value is not set anymore.

Ensure the source file is tracked by various cleanup functions.
|
| | |
| |
| |
| |
| |
| |
| | |
If the test does not need root, it can use 'SKIP_ROOT_DM_CHECK'.
For such test no actions needed root to initilize DM devices and
nodes will be take and test can check i.e. functional unit tests.
|

| |

| | |
Avoid logging warning when compared string is empty with -eq.
