Submission to Project: util-linux
Open Incident: #2663 at github.com/util-linux/util-linux/issues/2663
Component: util-linux/sys-utils
Files: tests/ts/dmesg kmsg interface files and related expected files
For issue #2609 Thomas and Zak pointed out the we need tests to verify
that the dmesg command works correctly and to allow us to compare the
results from PRINTK_CALLER id field tests provided by #2609 with the
standard (syslog interface) dmesg tests.
Except for a kmsg json test that Thomas added recently we don't have
basic dmesg tests for the kmsg interface to compare results against.
We added tests for the dmesg SYSLOG PRINTK_CALLER id interface so we
can compare against those tests.
Those tests were submitted with Issue #2637.
Those tests were created before Thomas added the new dmesg kmsg test
and I will rename those tests to match the naming scheme that Thomas
is using for tests that are specific to syslog interface and specific
to kmsg interface.
Issue #2609 introduces dmesg kmsg interface support for the PRINTK_CALLER
id field and provides tests to compare against the SYSLOG interface tests
added by #2637. Those tests also need to renamed to be consistent Thomas's
test naming scheme.
Here we've created tests for the dmesg kmsg interface following the
existing test structure for dmesg tests.
With the addition of this set of tests, we have tests for SYSLOG and
SYSLOG PRINTK_CALLER id field to compare against the kmsg and kmsg
PRINTK_CALLER id field tests.
Currently the only kmsg interface specific test that exists is the
kmsg-file test that Thomas added to test the dmesg kmsg interface for
json support.
Thomas also added code for the -K file interface to process dmesg ksmg
interface files for testing so we utilize that code here and add to it.
The kmsg-input file is expanded to provide statements and fields to
completely test the kmsg interface with tests that are equivalent to the
SYSLOG interface dmesg tests.
Additionally a ksmg-newlines file is added which provides kmsg format
for testing with indentation.
The output of the existing kmsg-file test is adjusted to match the
expanded kmsg-input file.
All tests follow the standard util-linux tests format used by dmesg for
unit tests.
Note: git doesn't handle binary files all that well and two files here
are binary files kmsg-input and kmsg-newlines because the format
of dmesg kmsg interface files requires binary format.
So those two files can't be sent in this patch file
Instead I will gzip those files and attach them to the Issue #2663
Please gunzip them and install them in your tests/ts/dmesg
directory that also holds the dmesg test files included here so
that the tests will pass. Sorry for the inconvenience of having
the binary files in separate gziped files.
