When a continuation like `.then([..] {...})` runs the lambda parameter
is not executed if it is a attached to a failed future. In this case
the lambda will be destroyed without running. In the case of kafka two
stage dispatch handling, we had the following:
first_stage.then([f = std::move(second_stage)] { ... }).then(...);
and we encountered a situation where the first and second stages failed.
when the continuation attached to the first_stage ran the captured `f`
exceptional future was destroyed (via the lambda that captured it). if
the first stage had not failed, then the lambda had proper handling for
a failed `f`.
This is an instance of a class of bug that is pretty hard to address. In this
case it was a bad_alloc that was thrown which caused the issue, not an
exceptional case that we explicitly handle.
to fix this we check if the first stage failed, and if so, we explicitly
consume the second stage to avoid this case. if the first stage
succeeds, then we operate as normal and background the second stage.

When the produce handler first stage failed the original code would also
immediately fail the second stage return future with the same error.
There is nothing wrong with those semantics, but the problem is that by
immediately failing the second stage the actual futures for the second
stage were run in the background while holding a live reference to the
request context, leading to the segfault below.
What's most interesting about this is that it requires the produce
request to have data for two partitions for the bug to trigger. In the
scenario the handling for one partition append succeeds in the first and
second stages, while the other partition append fails in the first
stage. In this case the first stage failure causes the request context
to be freed while the second stage still contains a live append request.
Is is the live append request that eventually touches the request
context.

This makes the recursion go away, but the deserialized output is all zeros. So that

Three integration tests that verify behavior of max_compactable_offset: - Randomized batch / messsage generaton with a limited number of keys. Verify that compaction only deletes messages less than this max. - Single key #1: fixed message test that checks that the boundaries of the compacted area are precisely as expected. - Single key #2: same as above, but with max_compactible_offset unset, we validate that compactions works as before.

This segfault is triggering as the test does something innocuous like logging a few string: ``` #0 0x7f875b0bbc1f in std::__1::basic_ostream<char, std::__1::char_traits<char> >::sentry::sentry(std::__1::basic_ostream<char, std::__1::char_traits<char> >&) (/vectorized/lib/libc++.so.1+0x65c1f) redpanda-data#1 0x5597c3979afc in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::__put_character_sequence<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, char const*, unsigned long) /vectorized/llvm/bin/../include/c++/v1/ostream:722:57 redpanda-data#2 0x5597c4079e44 in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::operator<<<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) /vectorized/llvm/bin/../include/c++/v1/ostream:1057:12 redpanda-data#3 0x5597c602c9f3 in seastar::logger::do_log(seastar::log_level, seastar::logger::log_writer&) /v/build/v_deps_build/seastar-prefix/src/seastar/src/util/log.cc:342:15 redpanda-data#4 0x5597c3c4ad20 in void seastar::logger::log<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::log_level, seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:231:17 redpanda-data#5 0x5597c3f23c51 in void seastar::logger::trace<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:385:9 redpanda-data#6 0x5597c3f14b95 in cloud_roles::signature_v4::sign_header(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/signature.cc:382:5 redpanda-data#7 0x5597c3bf1dfb in cloud_roles::apply_aws_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_aws_credentials.cc:83:23 redpanda-data#8 0x5597c3b8f88d in cloud_roles::apply_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_credentials.h:47:23 redpanda-data#9 0x5597c3b8c578 in test_aws_headers::test_method() /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/tests/credential_tests.cc:50:17 ``` What is suspicious is that this test is using seastar's logger from a non-seastar reactor thread. Taking a look we do see some things like this_shard_id() being called, but other than that it doesn't look like it should be problematic. But, it's unclear if there is more lurking there. Changed the test to run things that log using seastar logger on a seastar thread. Signed-off-by: Noah Watkins <noahwatkins@gmail.com>

The tee_wrapper helper was being used to set the ostream pointer for global logger to be an ostream instance that lived only on the stack, and not resetting it to something global like std::cerr after the test finished. This resulted in the following segfault in other tests that ran after the change but didn't make their own change to ostream pointer: ``` #0 0x7f875b0bbc1f in std::__1::basic_ostream<char, std::__1::char_traits<char> >::sentry::sentry(std::__1::basic_ostream<char, std::__1::char_traits<char> >&) (/vectorized/lib/libc++.so.1+0x65c1f) #1 0x5597c3979afc in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::__put_character_sequence<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, char const*, unsigned long) /vectorized/llvm/bin/../include/c++/v1/ostream:722:57 #2 0x5597c4079e44 in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::operator<<<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) /vectorized/llvm/bin/../include/c++/v1/ostream:1057:12 #3 0x5597c602c9f3 in seastar::logger::do_log(seastar::log_level, seastar::logger::log_writer&) /v/build/v_deps_build/seastar-prefix/src/seastar/src/util/log.cc:342:15 #4 0x5597c3c4ad20 in void seastar::logger::log<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::log_level, seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:231:17 #5 0x5597c3f23c51 in void seastar::logger::trace<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:385:9 #6 0x5597c3f14b95 in cloud_roles::signature_v4::sign_header(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/signature.cc:382:5 #7 0x5597c3bf1dfb in cloud_roles::apply_aws_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_aws_credentials.cc:83:23 #8 0x5597c3b8f88d in cloud_roles::apply_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_credentials.h:47:23 #9 0x5597c3b8c578 in test_aws_headers::test_method() /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/tests/credential_tests.cc:50:17 ``` This change resets the ostream pointer in the wrapper destructor.
