[dpdk-dev] [PATCH 0/7] Make unit tests great again

[dpdk-dev] [PATCH 0/7] Make unit tests great again

[Anatoly Burakov]

Previously, unit tests were running in groups. There were
technical reasons why that was the case (mostly having to do
with limiting memory), but it was hard to maintain and update
the autotest script.

In 18.05, limiting of memory at DPDK startup was no longer
necessary, as DPDK allocates memory at runtime as needed. This
has the implication that the old test grouping can now be
retired and replaced with a more sensible way of running unit
tests (using multiprocessing pool of workers and a queue of
tests). This patchset accomplishes exactly that.

This patchset conflicts with some of the earlier work on
autotests [1] [2] [3], but i think it presents a cleaner
solution for some of the problems highlighted by those patch
series. I can integrate those patches into this series if
need be.

[dpdk-dev] [PATCH 1/7] autotest: fix printing

[Anatoly Burakov]

Previously, printing was done using tuple syntax, which caused
output to appear as a tuple as opposed to being one string. Fix
this by using addition operator instead.

[dpdk-dev] [PATCH 2/7] autotest: fix invalid code on reports

[Anatoly Burakov]

There are no reports defined for any test, so this codepath was
never triggered, but it's still wrong because it's referencing
variables that aren't there. Fix it by passing target into the
test function, and reference correct log variable.

[Anatoly Burakov]

Autotest runner was still using python 2-style print syntax. Fix
it by importing print function from the future, and fix the calls
to be python-3 style.

[dpdk-dev] [PATCH 5/7] autotest: improve filtering

[Anatoly Burakov]

Improve code for filtering test groups. Also, move reading binary
symbols into filtering stage, so that tests that are meant to be
skipped are never attempted to be executed in the first place.
Before running tests, print out any tests that were skipped because
they weren't compiled.

[dpdk-dev] [PATCH 6/7] autotest: remove autotest grouping

[Anatoly Burakov]

Previously, all autotests were grouped into (seemingly arbitrary)
groups. The goal was to run all tests in parallel (so that autotest
finishes faster), but we couldn't just do it willy-nilly because
DPDK couldn't allocate and free hugepages on-demand, so we had to
find autotest groupings that could work memory-wise and still be
fast enough to not hold up shorter tests. The inflexibility of
memory subsystem has now been fixed for 18.05, so grouping
autotests is no longer necessary.

Thus, this commit moves all autotests into two groups -
parallel(izable) autotests, and non-arallel(izable) autotests
(typically performance tests). Note that this particular commit
makes running autotests dog slow because while the tests are now
in a single group, the test function itself hasn't changed much,
so all autotests are now run one-by-one, starting and stopping
the DPDK test application.

[dpdk-dev] [PATCH 7/7] autotest: properly parallelize unit tests

[Anatoly Burakov]

Now that everything else is in place, we can run unit tests in a
different fashion to what they were running as before. Previously,
we had all autotests as part of groups (largely obtained through
trial and error) to ensure parallel execution while still limiting
amounts of memory used by those tests.

This is no longer necessary, and as of previous commit, all tests
are now in the same group (still broken into two categories). They
still run one-by-one though. Fix this by initializing child
processes in multiprocessing Pool initialization, and putting all
tests on the queue, so that tests are executed by the first idle
worker. Tests are also affinitized to different NUMA nodes using
taskset in a round-robin fashion, to prevent over-exhausting
memory on any given NUMA node.

Non-parallel tests are executed in similar fashion, but on a
separate queue which will have only one pool worker, ensuring
non-parallel execution.

Support for FreeBSD is also added to ensure that on FreeBSD, all
tests are run sequentially even for the parallel section.

It may be interesting to work on lists of tests as done
in the following patch:
	http://dpdk.org/dev/patchwork/patch/40373/

The idea is to split tests in several categories:
	- basic and short test
	- longer and lower priority
	- performance test
As a long term solution, we can think about making category an attribute
inside the test itself?

These test categories do not conflict with my patchset as they 
ultimately rely on white/blacklisting, which will continue to work as 
before.

In my view, it really boils down to two things - either tests can be run 
in parallel with others (i.e. their result won't be affected by another 
independent DPDK test app instance), or not. On top of that, we can use 
blacklisting or whitelisting to define which tests will actually be run 
(i.e. define any "categories" we want), but their (non-)parallelism must 
always be respected to get good test results.

Have you looked at: http://mesonbuild.com/Unit-tests.html, at it would be
good to transition away from our own custom script infrastructure for the
tests.

There is already some support for running the unit tests using "meson
test", but it could do with some more cleanup e.g. to move the tests into
suitable suites (corresponding to the categories Thomas has suggested). We
could also do with specifying properly what tests are parallel-safe and
what aren't.

[dpdk-dev] [PATCH v2 00/10] Make unit tests great again

[Reshma Pattan]

Previously, unit tests were running in groups. There were technical reasons why that was the case (mostly having to do with limiting memory), but it was hard to maintain and update the autotest script.

In 18.05, limiting of memory at DPDK startup was no longer necessary, as DPDK allocates memory at runtime as needed. This has the implication that the old test grouping can now be retired and replaced with a more sensible way of running unit tests (using multiprocessing pool of workers and a queue of tests). This patchset accomplishes exactly that.

This patchset merges changes done in [1], [2] and [3]

[dpdk-dev] [PATCH v2 01/10] autotest: fix printing

[Reshma Pattan]

Previously, printing was done using tuple syntax, which caused
output to appear as a tuple as opposed to being one string. Fix
this by using addition operator instead.

[dpdk-dev] [PATCH v2 02/10] autotest: fix invalid code on reports

[Reshma Pattan]

There are no reports defined for any test, so this codepath was
never triggered, but it's still wrong because it's referencing
variables that aren't there. Fix it by passing target into the
test function, and reference correct log variable.

[dpdk-dev] [PATCH v2 03/10] autotest: make autotest runner python 2/3 compliant

[Reshma Pattan]

Autotest runner was still using python 2-style print syntax. Fix
it by importing print function from the future, and fix the calls
to be python-3 style.

[dpdk-dev] [PATCH v2 05/10] autotest: improve filtering

[Reshma Pattan]

Improve code for filtering test groups. Also, move reading binary
symbols into filtering stage, so that tests that are meant to be
skipped are never attempted to be executed in the first place.
Before running tests, print out any tests that were skipped because
they weren't compiled.

[dpdk-dev] [PATCH v2 06/10] autotest: remove autotest grouping

[Reshma Pattan]

Previously, all autotests were grouped into (seemingly arbitrary)
groups. The goal was to run all tests in parallel (so that autotest
finishes faster), but we couldn't just do it willy-nilly because
DPDK couldn't allocate and free hugepages on-demand, so we had to
find autotest groupings that could work memory-wise and still be
fast enough to not hold up shorter tests. The inflexibility of
memory subsystem has now been fixed for 18.05, so grouping
autotests is no longer necessary.

Thus, this commit moves all autotests into two groups -
parallel(izable) autotests, and non-arallel(izable) autotests
(typically performance tests). Note that this particular commit
makes running autotests dog slow because while the tests are now
in a single group, the test function itself hasn't changed much,
so all autotests are now run one-by-one, starting and stopping
the DPDK test application.

[dpdk-dev] [PATCH v2 07/10] autotest: properly parallelize unit tests

[Reshma Pattan]

Now that everything else is in place, we can run unit tests in a
different fashion to what they were running as before. Previously,
we had all autotests as part of groups (largely obtained through
trial and error) to ensure parallel execution while still limiting
amounts of memory used by those tests.

This is no longer necessary, and as of previous commit, all tests
are now in the same group (still broken into two categories). They
still run one-by-one though. Fix this by initializing child
processes in multiprocessing Pool initialization, and putting all
tests on the queue, so that tests are executed by the first idle
worker. Tests are also affinitized to different NUMA nodes using
taskset in a round-robin fashion, to prevent over-exhausting
memory on any given NUMA node.

Non-parallel tests are executed in similar fashion, but on a
separate queue which will have only one pool worker, ensuring
non-parallel execution.

Support for FreeBSD is also added to ensure that on FreeBSD, all
tests are run sequentially even for the parallel section.

You're also removing PCI autotest - commit message needs to call this

Why is "quit" an autotest? If you want to test "quit" functionality, i 
would suggest putting it at the end of non-parallel tests, to avoid 
situation where test prematurely stops (for example, this will happen on 
FreeBSD, where there's only one thread executing these tests).

But really, having it in this list is IMO dubious.

Here and in other "dump" autotests - do these dump tests work as 
autotests? Default autotest function expects a "Test OK" at the end of 
test, and i don't think dump autotests return that, so this will 
(should?) cause a very long timeout and a test failure. These should 
have "dump_autotest" as "Func" value - that function correctly parses 
output of dump autotests (or, to be more accurate, it doesn't - as long 
as test doesn't crash, it's considered to be successful :) ).

Also, for readability, we should move these dump tests together and have 
all dump tests one after the other.

Ok will add "Func" value  as dump_autotest and move all of the dump tests to end of  parallel list.

[dpdk-dev] [PATCH v2 09/10] autotest: update result for skipped test cases

[Reshma Pattan]

Fixed in autotest_test_funcs.py to handle test cases
which returns "Skipped" as result.
The issue was skipped test cases got timed out,
causing delay in autotests execution.

Is this patch still applicable? Patch 5 in these series causes skipped 
tests to not get executed in the first place, so by the time we reach 
this patch it is no longer a problem, i think.

[dpdk-dev] [PATCH v2 10/10] mk: update make targets for classified testcases

[Reshma Pattan]

Makefiles are updated with new test case lists.
Test cases are classified as -
P1 - Main test cases,
P2 - Cryptodev/driver test cases,
P3 - Perf test cases which takes longer than 10s,
P4 - Logging/Dump test cases.

Makefile is updated with different targets
for the above classified groups.
Test cases for different targets are listed accordingly.

[dpdk-dev] [PATCH v3 0/9] Make unit tests great again

[Reshma Pattan]

Previously, unit tests were running in groups. There were technical reasons why that was the case (mostly having to do with limiting memory), but it was hard to maintain and update the autotest script.

In 18.05, limiting of memory at DPDK startup was no longer necessary, as DPDK allocates memory at runtime as needed. This has the implication that the old test grouping can now be retired and replaced with a more sensible way of running unit tests (using multiprocessing pool of workers and a queue of tests). This patchset accomplishes exactly that.

This patchset merges changes done in [1], [2]

[dpdk-dev] [PATCH v3 1/9] autotest: fix printing

Previously, printing was done using tuple syntax, which caused
output to appear as a tuple as opposed to being one string. Fix
this by using addition operator instead.

[dpdk-dev] [PATCH v3 2/9] autotest: fix invalid code on reports

[Reshma Pattan]

There are no reports defined for any test, so this codepath was
never triggered, but it's still wrong because it's referencing
variables that aren't there. Fix it by passing target into the
test function, and reference correct log variable.

[dpdk-dev] [PATCH v3 3/9] autotest: make autotest runner python 2/3 compliant

[Reshma Pattan]

Autotest runner was still using python 2-style print syntax. Fix
it by importing print function from the future, and fix the calls
to be python-3 style.

Fixes: 54ca545dce4b ("make python scripts python2/3 compliant")

[dpdk-dev] [PATCH v3 5/9] autotest: improve filtering

[Reshma Pattan]

Improve code for filtering test groups. Also, move reading binary
symbols into filtering stage, so that tests that are meant to be
skipped are never attempted to be executed in the first place.
Before running tests, print out any tests that were skipped because
they weren't compiled.

[dpdk-dev] [PATCH v3 6/9] autotest: remove autotest grouping

[Reshma Pattan]

Previously, all autotests were grouped into (seemingly arbitrary)
groups. The goal was to run all tests in parallel (so that autotest
finishes faster), but we couldn't just do it willy-nilly because
DPDK couldn't allocate and free hugepages on-demand, so we had to
find autotest groupings that could work memory-wise and still be
fast enough to not hold up shorter tests. The inflexibility of
memory subsystem has now been fixed for 18.05, so grouping
autotests is no longer necessary.

Thus, this commit moves all autotests into two groups -
parallel(izable) autotests, and non-arallel(izable) autotests
(typically performance tests). Note that this particular commit
makes running autotests dog slow because while the tests are now
in a single group, the test function itself hasn't changed much,
so all autotests are now run one-by-one, starting and stopping
the DPDK test application.

[dpdk-dev] [PATCH v3 7/9] autotest: properly parallelize unit tests

[Reshma Pattan]

Now that everything else is in place, we can run unit tests in a
different fashion to what they were running as before. Previously,
we had all autotests as part of groups (largely obtained through
trial and error) to ensure parallel execution while still limiting
amounts of memory used by those tests.

This is no longer necessary, and as of previous commit, all tests
are now in the same group (still broken into two categories). They
still run one-by-one though. Fix this by initializing child
processes in multiprocessing Pool initialization, and putting all
tests on the queue, so that tests are executed by the first idle
worker. Tests are also affinitized to different NUMA nodes using
taskset in a round-robin fashion, to prevent over-exhausting
memory on any given NUMA node.

Non-parallel tests are executed in similar fashion, but on a
separate queue which will have only one pool worker, ensuring
non-parallel execution.

Support for FreeBSD is also added to ensure that on FreeBSD, all
tests are run sequentially even for the parallel section.

The above three tests don't look like autotests to me. I have no idea 
what they are for, but either they need a special function, or they need 
to be taken out.

These commands needs to be run manually from test cmd prompt to various set rxtx mode, rxtx rate and rxtx direction .
These can be used to verify pmd perf test  with vaiours set of above values.

So this can be removed from autotest.

We do have PMD perf tests in the script - do they call these functions? 
If they are required for PMD autotests, maybe PMD autotests deserve a 
special test function calling these commands before running the tests?

(if they also work without these commands, then we can perhaps postpone 
this to 18.11)

[dpdk-dev] [PATCH v3 9/9] mk: update make targets for classified testcases

[Reshma Pattan]

Makefiles are updated with new test case lists.
Test cases are classified as -
P1 - Main test cases,
P2 - Cryptodev/driver test cases,
P3 - Perf test cases which takes longer than 10s,
P4 - Logging/Dump test cases.

Makefile is updated with different targets
for the above classified groups.
Test cases for different targets are listed accordingly.

[dpdk-dev] [PATCH v4 0/9] Make unit tests great again

[Reshma Pattan]

Previously, unit tests were running in groups. There were technical reasons why that was the case (mostly having to do with limiting memory), but it was hard to maintain and update the autotest script.

In 18.05, limiting of memory at DPDK startup was no longer necessary, as DPDK allocates memory at runtime as needed. This has the implication that the old test grouping can now be retired and replaced with a more sensible way of running unit tests (using multiprocessing pool of workers and a queue of tests). This patchset accomplishes exactly that.

This patchset merges changes done in [1], [2]

[1] http://dpdk.org/dev/patchwork/patch/40370/
[2] http://patches.dpdk.org/patch/40373/

v4: Removed non auto tests set_rxtx_mode, set_rxtx_anchor and set_rxtx_sc

[dpdk-dev] [PATCH v4 1/9] autotest: fix printing

[Reshma Pattan]

Previously, printing was done using tuple syntax, which caused
output to appear as a tuple as opposed to being one string. Fix
this by using addition operator instead.

[dpdk-dev] [PATCH v4 2/9] autotest: fix invalid code on reports

[Reshma Pattan]

There are no reports defined for any test, so this codepath was
never triggered, but it's still wrong because it's referencing
variables that aren't there. Fix it by passing target into the
test function, and reference correct log variable.

it by importing print function from the future, and fix the calls
to be python-3 style.

[dpdk-dev] [PATCH v4 5/9] autotest: improve filtering

[Reshma Pattan]

Improve code for filtering test groups. Also, move reading binary
symbols into filtering stage, so that tests that are meant to be
skipped are never attempted to be executed in the first place.
Before running tests, print out any tests that were skipped because
they weren't compiled.

[dpdk-dev] [PATCH v4 6/9] autotest: remove autotest grouping

[Reshma Pattan]

Previously, all autotests were grouped into (seemingly arbitrary)
groups. The goal was to run all tests in parallel (so that autotest
finishes faster), but we couldn't just do it willy-nilly because
DPDK couldn't allocate and free hugepages on-demand, so we had to
find autotest groupings that could work memory-wise and still be
fast enough to not hold up shorter tests. The inflexibility of
memory subsystem has now been fixed for 18.05, so grouping
autotests is no longer necessary.

Thus, this commit moves all autotests into two groups -
parallel(izable) autotests, and non-arallel(izable) autotests
(typically performance tests). Note that this particular commit
makes running autotests dog slow because while the tests are now
in a single group, the test function itself hasn't changed much,
so all autotests are now run one-by-one, starting and stopping
the DPDK test application.

[dpdk-dev] [PATCH v4 7/9] autotest: properly parallelize unit tests

[Reshma Pattan]

Now that everything else is in place, we can run unit tests in a
different fashion to what they were running as before. Previously,
we had all autotests as part of groups (largely obtained through
trial and error) to ensure parallel execution while still limiting
amounts of memory used by those tests.

This is no longer necessary, and as of previous commit, all tests
are now in the same group (still broken into two categories). They
still run one-by-one though. Fix this by initializing child
processes in multiprocessing Pool initialization, and putting all
tests on the queue, so that tests are executed by the first idle
worker. Tests are also affinitized to different NUMA nodes using
taskset in a round-robin fashion, to prevent over-exhausting
memory on any given NUMA node.

Non-parallel tests are executed in similar fashion, but on a
separate queue which will have only one pool worker, ensuring
non-parallel execution.

Support for FreeBSD is also added to ensure that on FreeBSD, all
tests are run sequentially even for the parallel section.

[dpdk-dev] [PATCH v4 9/9] mk: update make targets for classified testcases

[Reshma Pattan]

Makefiles are updated with new test case lists.
Test cases are classified as -
P1 - Main test cases,
P2 - Cryptodev/driver test cases,
P3 - Perf test cases which takes longer than 10s,
P4 - Logging/Dump test cases.

Makefile is updated with different targets
for the above classified groups.
Test cases for different targets are listed accordingly.
