Just for visibility for whoever is watching this,
{{ChecksummingTransformerTest}} will be removed in CASSANDRA-15299. We can keep
this open until that merges though...

bq. Reverting CASSANDRA-1 fixes corruptionCausesFailure with seed
71671740653044L for me
Sorry I don't fully follow, can you elaborate [~spod]? There are 3 issues with
the test/feature (may have missed something, going off memory).
1) corruption can cause lz4 to crash the JVM. This was fixed in
CASSANDRA-15556 by using the "safe" methods rather than "fast"
2) corrupted lz4 stream may not fail and may produce output != input; this is
still an issue and the tests fail periodically with this.
3) generators generated too much garbage. CASSANDRA-1 switched to fixed
memory and switched from strings (charset depends on the test environment since
it doesn't define which charset to use) to raw bytes. Given the fact the
generated data changed the seeds which failed before no longer fail, and the
seeds that fail now did not fail with the old generators; both generators were
able to reproduce #2, but with different seeds.

Reverting CASSANDRA-1 fixes corruptionCausesFailure with seed
71671740653044L for me. But semantics for generators change with that as well,
so I'm not 100% sure its the actual cause.

If the argument that everything will be better with that Jira, I’m fine for
now. I am curious why the condition happens but if checksum is done on
compressed data it’s not likely to hit it.
I rather keep the test running. Yes it’s red, yes it’s noise; it’s calling out
a bug that isn’t fixed yet though.

I wasn't suggesting we close this JIRA, so it would still effectively be marked
flaky and a blocker for 4.0. Marking it {{@Ignore}} would just improve the
signal:noise ratio for builds broken by other things.

If we aren't able to fix it now / are waiting for a future change, can we mark
it as flaky (maybe this JIRA being open is fine) in some way but not @Ignore
it? I think that would more likely ensure we don't forget it -- especially
since its been effective at finding bugs. The test should apply to the code
post-15529 as well.

{quote}[~samt] would it be possible for you to take a look?{quote}
Sure, but I won't be able to get to it immediately. This will go away with
CASSANDRA-15299, so if it's causing test failures maybe we can {{@Ignore}} the
test for now and I'll come back to it if 15299 gets bumped from 4.0.

Sent patch for CASSANDRA-15556 which makes it so the JVM doesn't crash anymore;
with that in the only remaining issue I know of is
{code}
transformInbound(transformOutboun(input)) != input
{code}
[~samt] would it be possible for you to take a look? I provided a set of seeds
which fail, so can rerun the test with that seed to reproduce the failure.

Created a different JIRA for the memory issue since I didn't make the test not
flaky, I just made it so it doesn't GC anymore.
I published the test which causes the JVM to crash here

Im trying to get the data for the core dump, but made the test stop having GC

The root change was that I didn't follow the style of
{code}
private Gen inputs()
{
Gen randomStrings =
strings().basicMultilingualPlaneAlphabet().ofLengthBetween(0, MAX_INPUT_SIZE);
Gen highlyCompressable = strings().betweenCodePoints('c',
'e').ofLengthBetween(1, MAX_INPUT_SIZE);
return randomStrings.mix(highlyCompressable, 50);
}
{code}
instead my first patch was basically the same as randomStrings. If you run
with just randomStrings you don't see this after a ton of runs. If you run
with highlyCompressable you will eventually see this.
After changing the byte generator to follow this range of bytes I was able to
hit it every run...

ok, have a new version of the patch which is able to hit the failure case, but
we went from "flaky" to "every single run"... progress? =D

bq. Is this your finding?
Yes, that matches what I see (or sometimes the jvm segfaults in LZ4). Your
patch with 500 examples added back in corruptionCausesFailure passes
consistently.

The output from quick theories doesn't work in isolation; the way the string is
generated then converted to bytes ins't reproducible without relying on the
seed to create the same string. I changed the text to print out the hex of the
bytes and when you run with those bytes the test fails
Here is the hex for the bytes failing

Not a huge fan of fixing the seed. The intention is for the test to search
different permutations each time its run, not a fixed set (the seed is meant to
help debug once you find that failure -- assuming its deterministic). One seed
may find the original bug this test found but not other/future bugs.
Ideally we'd keep the example count high but balancing that against memory
usage and runtime goals/constraints so we don't make the suites unnecessarily
long for code that hasn't changed.

bq. "it" is the failing case; sorry for the confusion. By lowering the examples
we will need to run the test more before we see the failing case.
That is not true, though. The key to reproducing the failing case is defining
the seed that makes it fail, which can then reproduce it with only 20 examples
(I updated my branch to reflect this, and isolated it to the
corruptionCausesFailure test. You still need to override the timeout to be
long enough for it to fail, I use -Dtest.timeout=6000) I probably did a
few thousand runs before I came across that seed, though.
bq. I took a stab at fixing it and attaching a hack patch to the JIRA to show;
This looks good but you also removed the examples from corruptionCausesFailure.
With them added back everything seems to pass fine at 200 examples. I'll try
another run with 500 and report back.

"it" is the failing case; sorry for the confusion. By lowering the examples we
will need to run the test more before we see the failing case.
bq. I ran at 4G and it still failed at 200 examples (I didn't try any other
sizes though)
This then sounds like the generators produce too much garbage. I took a stab at
fixing it and attaching a hack patch to the JIRA to show; basically move away
from String since that produces a ton of garbage. With the patch and a failing
test case, the test completes in 200ms (900ms if you run in isolation).
[~samt] don't know the test well but when I run it (not patched) in a debugger
with 1000 examples, I see the call
https://github.com/apache/cassandra/blob/trunk/test/unit/org/apache/cassandra/transport/frame/checksum/ChecksummingTransformerTest.java#L118
2 times; so only 2 out of 1k runs hits that check. My patch doesn't hit it
(after a few runs), but could always tweak the bytes to match the expected
input.

David Capwell commented on CASSANDRA-15313:

Lowering the examples means we need more runs to see it. Looking at the JVM we
spin up I see its -Xmx1024m so we have 1g of heap; If you run the test with 2-4
does it still fail?
CI runs the test with the following
{code}
ant testclasslist -Dtest.classlistfile=<(echo
org/apache/cassandra/transport/frame/checksum/ChecksummingTransformerTest.java)
-Dtest.classlistprefix=unit
{code}
Quickly looking at the code it transfers Strings as a wrapper for byte[]. This
is more garbage to generate and toss so could also be reduced by using byte[]
instead.
Do we have a heap dump of the test so we know what the top memory was from?
500 isn't a large example size, so this sounds more like we could improve the
generators.

bq. I do see the timeout on linux with lz4 1.7.1, although I didn't manage to
trigger the crash
You probably need to override the test timeout so it can complete.
bq. +1 on lowering the number of examples to stabilise the test.
I committed the reduction to 35 examples.

Probably not a surprise, but it doesn't seem to repro on mac or in circle. I do
see the timeout on linux with lz4 1.7.1, although I didn't manage to trigger
the crash. I agree looks like maybe a bug in lz4, I don't have time right now,
but when I do I'll pull out a minimal repro and submit it to the lz4 project.
+1 on lowering the number of examples to stabilise the test.

This is mostly due to the two places where a rather large example size is used,
500. I did many runs lowering this number until I could be sure there were no
timeouts, and that number is 35. However, once the test was not always timing
out (at around 40 examples) it discovered a seed that always fails:
{code:java}

[junit-timeout] Test
org.apache.cassandra.transport.frame.checksum.ChecksummingTransformerTest FAILED
{code}
Sometimes instead of failing the test, it will crash the jvm here:
{code:java}
[junit-timeout] # C [liblz4-java4100719362944375598.so+0x5eb7]
LZ4_decompress_fast+0x117
{code}
I've reproduced this against lz4 1.4.0, 1.4.1, 1.5.0, 1.5.1, 1.6.0, 1.7.0, and
1.7.1. I think beyond the flakiness which can be solved by reducing the amount
of examples, we've got a legitimate bug in lz4. I pushed the branch to
reproduce here: https://github.com/driftx/cassandra/tree/CASSANDRA-15313
WDYT, [~samt]?
