A gzipped file containing the relevant part of the log for the threaded, non-debugging configuration can be found here.

@atoomic @toddr Can you take a look? Suggest comparing with last previous smoke-test on this host with this configuration on branch.

atoomic commented 4 years ago

A quick scan of the log file, show multiple warnings and many Direct leak or Indirect leak my first question is, can we compile 5.32.0 with such a configuration? Are the errors unique to our branch?

I'm going to try to reproduce it, but I'm not sure I got the correct environment for it.

atoomic commented 4 years ago

Configure options seems to be:

-Dcc="ccache clang" -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address  -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address" (*1)

and

-Dcc="ccache clang" -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address  -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address" -Duseithreads (*1)

This tester uses this configuration on Perl 5 blead and all branches and has done so for a long time.

I myself have never successfully compiled with asan.

atoomic commented 4 years ago

After testing on a fresh Fedora 32 install with the same configuration option I can notice this error

git clean -dxf; ./Configure -des -Dcc="ccache clang" -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address  -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address"

I can see the exact same issue building v5.32.0 we can close this case, issues noticed here also exist on v5.32.0

this seems to be ok with blead@eb992c6f going to perform a bisect

We previously had failures in t/re/pat.t and t/re/pat_thr. on this host with this configuration on this branch. See: http://perl.develop-help.com/raw/?id=255189 http://perl.develop-help.com/raw/?id=255476

jkeenan commented 4 years ago

t/re/pat.t and t/re/pat_thr.t appear to fail frequently on this host. See, e.g., http://perl5.test-smoke.org/submatrix?test=../t/re/pat.t&pversion=5.33.1.

Is this perhaps a situation where these tests have been steadily failing on a given configuration across platforms, but never had a bug ticket filed about them?

atoomic commented 4 years ago

The git bisect took some time to run but it appears that the fixed came from https://github.com/Perl/perl5/commit/6841cd5977c2d35ad75233734c66983a65613fce which was added in v5.33.1 dev cycle

6841cd5977c2d35ad75233734c66983a65613fce is the first bad commit

    Fix leak GH #18054

    This was a simple matter of one path failing to free the memory.

Question: do we want to cherry pick this change to our branch? I would say it s probably a good thing as the scope seems pretty small?

@jkeenan any opinions?

As a matter of fact, right now, I'm using my Linode to try to build with asan. So I'll check this out.

Thanks. jimk

jkeenan commented 4 years ago

I tried building p7 with asan on my Linode. It has an older Debian, so the current version of clang is just 4.0. I configured as follows:

git clean -dxf; ./Configure -des -Dcc="clang-4.0" -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address  -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address"; make test_prep

I then called:

cd t; TEST_JOBS=1 ./perl harness -v re/pat.t; cd -

Excerpt from output:

...

Test Summary Report
-------------------
re/pat.t (Wstat: 256 Tests: 1022 Failed: 0)
  Non-zero exit status: 1
Files=1, Tests=1022, 89 wallclock secs ( 0.31 usr  0.04 sys + 32.27 cusr 55.35 csys = 87.97 CPU)
Result: FAIL

So: non-threaded build: All non-skipped unit tests passed, but AddressSanitizer reported leaks and test was graded FAIL

I then realized that since I had built without threads, I wouldn't be able to run t/re/pat_thr.t. So I added -Dusethreads to the config args and attempted to rebuild. However, make failed with output shown here.

So I applied khw's patch and rebuilt unthreaded and re-tested.

$ cd t; TEST_JOBS=1 ./perl harness -v re/pat.t re/pat_thr.t 1>../err 2>&1; cd - ; vi err
...
ok 1021 - gh17743: test regexp corruption (1)

Files=2, Tests=1022, 89 wallclock secs ( 0.18 usr  0.02 sys + 32.19 cusr 55.32 csys = 87.71 CPU)
Result: PASS

So, for me, that patch cleared up the problem in t/re/pat.t on unthreaded asan builds. Let's apply it.

@jkeenan this is now in alpha-dev-02-strict and merged as 9ecd4bde

atoomic commented 4 years ago

IMO we can close this case

jkeenan commented 4 years ago

IMO we can close this case

What about the threaded build problem?

atoomic commented 4 years ago

I've not tested it, but regarding the output this looks like very similar. I can confirm it then close this case

atoomic commented 4 years ago

using blead@90f5f043 or v5.32.0 or alpha-dev-02-strict@c7dd377c both are broken when compiling with threads

git clean -dxf; ./Configure -Dusedevel -des -Dcc="ccache clang" -Accflags="-Werror=declaration-after-statement -g -fno-omit-frame-pointer -fsanitize=address  -fno-common -fsanitize-blacklist=`pwd`/asan_ignore" -Aldflags="-fsanitize=address" -Duseithreads

So yes this is broken in our alpha-dev-02-strict in the same way it's broken upstream. We need to report it upstream and close this case.
