[PATCH 0/6] Move remaining x86 Travis jobs to the gitlab-CI

[PATCH 0/6] Move remaining x86 Travis jobs to the gitlab-CI

[Thomas Huth]

Since Travis changed their policies, travis-ci.org will soon become
completely useless for the QEMU project. We should now really make sure
that we move the remaining tests as good as possible to the gitlab-CI
instead. Since the gitlab-CI has already quite a lot of jobs, I tried
to squeeze the missing bits as good as possible into the existing jobs
instead of adding a separate job for each and ever test that we had
in the Travis-CI - I hope that will help to avoid increasing the stress
on the CI system too much.

  travis.yml: Move gprof/gcov test across to gitlab

Thomas Huth (5):
  travis.yml: Move the -fsanitize=undefined test to the gitlab-CI
  travis.yml: Move the --enable-modules test to the gitlab-CI
  travis.yml: Remove the --enable-debug jobs

[PATCH 1/6] travis.yml: Move gprof/gcov test across to gitlab

[Thomas Huth]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

Similarly to commit 8cdb2cef3f1, move the gprof/gcov test to GitLab.

The coverage-summary.sh script is not Travis-CI specific, make it
generic.

With build-tcg it generates an empty report, e.g., 
https://gitlab.com/wainersm/qemu/-/jobs/1005923421

Shouldn't it run `make check`?

D'oh, you're right. I think we need to run at least a "make check-unit" 
here. I'll rework my patch accordingly...

By the way, it's broken on Travis since a long time, e.g. with version 5.0 
there is already only a stack trace:

https://travis-ci.org/github/qemu/qemu/jobs/680661167#L8411

Seems like nobody noticed this for almost a year now...

doh - the check_coverage was an after_success step so never influenced
the result. It was only a band aid really though - it would be better if
we published the html coverage report on gitlab's pages (like we now do
for annotated gtags source: https://qemu-project.gitlab.io/qemu/src/

[PATCH 2/6] travis.yml: Move the -fsanitize=undefined test to the gitlab-CI

[Thomas Huth]

Add it to the existing Clang job and also add a job that covers the
linux-user code with this compiler flag. To make sure that the detected
problems are not simply ignored, let's also use "-fno-sanitize-recover=..."
now instead.

[PATCH 4/6] travis.yml: Remove the --enable-debug jobs

[Thomas Huth]

We already have such jobs in the gitlab-CI ("build-some-softmmu" and
"build-user-plugins"), so we can simply drop these from the Travis-CI.

Those jobs --enable-debug-tcg. Shouldn't at least one --enable-debug?

[PATCH 5/6] target/s390x/arch_dump: Fixes for the name field in the PT_NOTE section

[Thomas Huth]

According to the "ELF-64 Object File Format" specification:

"The first word in the entry, namesz, identifies the length, in
 bytes, of a name identifying the entry’s owner or originator. The name field
 contains a null-terminated string, with padding as necessary to ensure 8-
 byte alignment for the descriptor field. The length does not include the
 terminating null or the padding."

So we should not include the terminating NUL in the length field here.

Also there is a compiler warning with GCC 9.3 when compiling with
the -fsanitize=thread compiler flag:

 In function 'strncpy',
    inlined from 's390x_write_elf64_notes' at ../target/s390x/arch_dump.c:219:9:
 /usr/include/x86_64-linux-gnu/bits/string_fortified.h:106:10: error:
  '__builtin_strncpy' specified bound 8 equals destination size
  [-Werror=stringop-truncation]

Since the name should always be NUL-terminated, we can simply decrease
the size of the strncpy by one here to silence this warning. And while
we're at it, also add an assert() to make sure that the provided names
always fit the size field (which is fine for the current callers, the
function is called once with "CORE" and once with "LINUX" as a name).

[PATCH 6/6] travis.yml: Move the -fsanitize=thread compile-testing to the gitlab-CI

[Thomas Huth]

It's only about compile-testing (there is too much noise when running
the tests), so let's simply add the -fsanitize=thread flag to a job that
only compiles the sources. The "build-gprof-gcov" seems to be a good
candidate.

It will be a little weird to see a gprof/gcov failing with a sanitize 
error, but it seems indeed the best job.

Allow me to double-check: doesn't it need -g to show the line numbers?

Never mind. It compiles with "-O2 -g". So:
