Yes!
OCI has an ARM64 VM in their free tier!
They also provide easy integration with GitHub Actions -
https://blogs.oracle.com/cloud-infrastructure/post/announcing-github-actions-arm-runners-for-the-arm-compute-platform-on-oracle-cloud-infrastructure
But the issue here is that GitHub Actions self-hosted runners are not
recommended for public/OSS projects because bad people can execute malware
on your VM via (meaningless) Pull Requests.

This setup uses QEMU -
https://github.com/phpmyadmin/phpmyadmin/blob/c90affe793b56fb6f5e1c7eed676ec9031fb1480/.github/workflows/tests.yml#L51
.
It works but it is much slower than using a real ARM64 machine/VM.

I am not sure whether you understood me. Or maybe I didn't understand you.
Anyway, let me rephrase:
TravisCI provides two types of ARM64 VMs - arm64 (powered by Equinix Metal)
and arm64-graviton2 (by AWS Graviton2).
You, as a user, can use any or both of them in your .travis.yml.
I prefer the AWS Graviton2 instances because there are less issues with
them.
So, instead of disabling the ARM64 CI job I suggest to try with
arm64-graviton2. Here is a sample setup for it -
https://github.com/apache/wicket/blob/270a5a43970cd975539331b21a34bd83a59c9c39/.travis.yml#L18-L22

Yeah, these machines are really fantastic. The real problem anyway is
likely that nowadays everyone is interested in testing on arm and very
few have one available, let alone even a cross-compiler, so I suspect
that these days a lot of people enable arm builds in such CI environments
because it's the only way they have to make sure their code builds there
at all.

TravisCI just announced some improvements related to 'arch: arm64' (using
Equnix Metal machines) - https://blog.travis-ci.com/2021-08-06-oss-equinix.
But I also had some similar problems with them recently and replaced the
config with 'arch: arm64-graviton2; group: edge; virt: vm;', i.e. AWS
Graviton2 machines. In my experience they behave more stable!

Yes I noticed a few of these lately, and sometimes it even looked like

Let me explain the change.
At
https://github.com/haproxy/haproxy/blob/a8dbdf3c4b463a3f3e018f0cd02fa0d8d179bc07/.travis.yml#L113-L117
you
may see the default 'install' phase.
At
https://github.com/haproxy/haproxy/blob/a8dbdf3c4b463a3f3e018f0cd02fa0d8d179bc07/.travis.yml#L12-L19
is
the default environment.
They are used by every job from the matrix (
https://github.com/haproxy/haproxy/blob/a8dbdf3c4b463a3f3e018f0cd02fa0d8d179bc07/.travis.yml#L35
).
But each job can override the default environment and any of the phases
(before_install, install, after_install, script).
For the ARM64 build I overwrote the 'install' phase by copying the default
one and removing the execution of the build_ssl() function (the one that
builds OpenSSL from source) and I also overwrote the environment to update
the values of SSL_INC and SSL_LIB variables.
'openssl' and 'libssl-dev' packages are already installed in the Ubuntu
image used by TravisCI so there is nothing to install manually.. I've added
a comment (
https://github.com/haproxy/haproxy/blob/a8dbdf3c4b463a3f3e018f0cd02fa0d8d179bc07/.travis.yml#L47)
to remind us how it works.

Re: [PATCH] enable arm64 builds in travis-ci

[Martin Grigorov]

Thank you for applying the patch!

The ARM64 build passed at
https://travis-ci.com/github/haproxy/haproxy/jobs/335338296 !
But it passes only for the builds which have 'haproxy-mirror' :
https://travis-ci.com/github/haproxy/haproxy/builds
I am not sure what exactly "haproxy-mirror" is in the TravisCI config.
The builds which do not have "haproxy-mirror" next to the branch name also
do not have ARM64 build at all, e.g.
https://travis-ci.com/github/haproxy/haproxy/builds/166573019.

One thing that I notice is that the successful link above has *jobs *and
the failing one: *builds *before the job/build id.

Subject: [PATCH] CI: travis-ci: switch arm64 builds to use openssl from distro

there are ongoing arm64 failures in travis-ci. we suspect that
build stucks on scripts/build-ssl.sh which is called during build.
let us try to use openssl from ubuntu distro and not build it
ourselves. to achive that we add "install" section without
build-ssl.sh

I will resend a patch with detailed information.


as for "purge a cache", it was a suggestion to Martin to purge it manually
in his own travis-ci project.
it usually helps to find caveats (for example, you still get files from
cache which is not desireable)

it's just for pre-checkin test.

Could you please handle Martin's patch, possibly cut it into several
pieces if relevant and add a commit message indicating what it does
(and why) ? Martin is not at ease with Git (which is not a problem),
and it seems only him and you understand how the reasons of the changes
in his patch. At least it's totally unclear to me why there's a new
install target for arm64 and why there's a special "make" invocation
there.

Feel free to add your "purge cache" change as an extra patch if needed.
But in any case, please make sure it's still possible to follow the
impact of each change, because we've touched many things blindly for
a while on this arm64 issue and most of the changes were basically
"let's see if this helps", which is a real mess :-/

Thanks!

Re: [PATCH] enable arm64 builds in travis-ci

that should work indeed.


also, I'd suggest to purge travis-ci cache (if you are build in your own
fork).
some travis related issue might be related when something is took from
cache (which was not supposed to happen)

 Hi,

 I've created https://github.com/haproxy/haproxy/pull/630
 With this change the build passed successfully for 5 mins and 7 secs
 for ARM64.

 Please let me know if you prefer me to send it as an attached .patch

 I created several topics (no answer yet).

 as for travis-ci rights, it's totally undocumented. but I suspect
 travis grants
 rights based on github rights. i.e. github admin becomes travis admin
 as well.

 Good point, that can also be a solution. But it remains completely
 hackish. It's basically abusing a versioning system to use it as a
 messaging system to indicate "please build with this".

Hi,

I've created https://github.com/haproxy/haproxy/pull/630
With this change the build passed successfully for 5 mins and 7 secs for
ARM64.

Please let me know if you prefer me to send it as an attached .patch file
here. (I haven't used `git format-patch` before :-/).

I wish I could. I've visited all visible menus and even settings under
my face, and couldn't find anything related to user management nor
permissions :-(  It's fairly possible it's hidden somewhere, I'm not
good at spotting hidden menus in modern interfaces. So for now I'm a

You can avoid this by making changes to .travis.yml directly in Travis UI.
At the right-top part of the page there is "More options" menu. Select
"Trigger build" and in the dialog you can paste "Custom config". Once you
are happy with the outcome you can push it in your Git repo.

Back to the main topic:
Now it fails with totally new reason. It doesn't even start installing the
dependencies.
It started failing this way since:
https://github.com/haproxy/haproxy/commit/8d76af55e10f018ab3d482125433be4992884372
You can try the "manual approach" by reverting this change! ;-)

OK now pushed. It's really annoying to work blindly like this. The
build model Travis uses is broken by design. Requiring to commit
something for testing is utterly wrong. And doing so within the
project that's supposed to being test is further wrong. We already
have 44 patches only on .travis.yml! If this continues like this,
I predict that a "pre-CI" solution will appear to test if your
change is likely to trigger a travis error before it gets merged...

No idea but if it works on your repo it should there as well. I
really think that the logs are just shown a bit further as Martin
and I predicted :-)

Let's increase the timeout to see if it has a chance to finish, no ?

Willy

Re: [PATCH] enable arm64 builds in travis-ci

[Илья Шипицин]

as far as I understand, arm64 is run inside containers. something like
docker or lxd.

"Processing triggers for dbus (1.12.2-1ubuntu1.1) ..."


dbus is not supposed to be available from container, right ?

I would start with disabling pcre2. It should change output and uncover
truth. I will send a patch in couple of days (if that won't help, we'll
play with timeouts)

Martin, can you please try to contact travis support ?

build-ssl.sh is called from "install" section. we just need to add separate
"install" section for arm64

We don't know how long it gets cached so if we increase it we'll have to
leave it.

I think we can do it directly from the build-ssl script if needed.
Basically something ugly more or less like this:

   if [ "$(uname -m)" = "aarch64" ]; then
  apt install ...
  ln -s /usr/lib64 $HOME/opt/lib
  ln -s /usr/inculde $HOME/opt/include

I still believe the problem is in the time needed to build OpenSSL, not in
apt[-get].

We can increase temporarily the travis_wait to 60 just to cache the build
of 1.1.1f and then remove '60' again. Although if this is the problem then
'travis_wait 60 ...' won't do any harm for the next builds because it will
use the cache and return in few secs.

I like the idea to install openssl with apt but I am not sure whether we
can do this *only* for ARM64.

But we don't even know if we all end up on the same build nodes, and
it's likely that it's not the case since yours finishes.

Well, for #1 I don't think that changing pcre2 will have any impact there
because it's obvious that we're facing output buffer truncation and that
the problem happens after though we don't know how far after. For #2, not
using travis' apt, maybe we'd gain slightly better control, but it's not
even certain and it's possible we might not benefit from certain caches,
so I'm having doubts. For #3, interacting with their support channel, why
not, if you're willing to engage into this. If at least they can bring us
a complete untruncated output of a failed build, that would help.

I continue to think that avoiding building standard packages in the VMs
should be the priority. Our goal is not to test if openssl can be built
and used there but if haproxy can be built and used there. When it's the
only option to test integration with certain components, that's fine.
Here I think that openssl is sufficiently covered on other platforms so
we don't necessarily need to rebuild it ourselves and we can use the
distro's version.

Thanks,
Willy

We could, but 120 (2 hours) seems a bit extreme. It also means we can steal
2 hours of CPU there in case something goes wrong.

I'm wondering why instead we don't fallback on an already packaged version
of OpenSSL for this platform. I mean, sure it's convenient to test the
latest version but it's already tested on x86 and we could very well use
any other version already packaged on the distro present there. This would
solve the problem and even increase versions coverage.

Ilya, what do you think ?

there are few options

1) setup separate "apt" key for "arm64", we do not use pcre2 here

2) use direct "apt-get" call, not travis "apt" plugin (maybe we can control
buffering that way)

3) interoperate with travis via support channel

4) wait until it is resolved by itself

Re: [PATCH] enable arm64 builds in travis-ci

[Martin Grigorov]

Hi,

I think I understand why it started failing.
It must have started failing when you updated the version of OpenSSL.
.travis.yml caches ~/opt folder between builds. After the update to 1.1.1f
the build doesn't see the OpenSSL binaries in the cache anymore and tries
to download it and build it.
But as I've noticed in my attempt to build HAProxy with Docker+QEMU the
build of OpenSSL is taking too long.
The build of OpenSSL is wrapped with travis_wait to reduce the writes to
stdout but the default time for travis_wait is 20 mins and this is not
enough to build OpenSSL.
Due to
https://travis-ci.community/t/output-is-truncated-heavily-in-arm64-when-a-command-hangs/7630
TravisCI
does not properly report that the problem is at build_ssl() step but shows
the last chunk of the buffered response and this confuses us all.
I think the build will become green if we extend travis_wait to a higher
value (
https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received).
I don't remember where I have read it but I think the upper limit is 120
mins.
@Willy: could you please change
https://github.com/haproxy/haproxy/blob/master/.travis.yml#L112 to:

travis_wait 120 bash -c 'scripts/build-ssl.sh >build-ssl.log 2>&1' || (cat
build-ssl.log && exit 1)

i.e. add '120' after travis_wait

This should give it the time to download and install OpenSSL 1.1.1f and to
cache it. If the build passes once then the next builds should be much
faster because OpenSSL will be used from the cache.

Regards,
Martin

Cool, that tends to confirm the issue remains a bit random. There
is actually something I don't like in the build report, which is
that the "Setting up libpcre2" line is truncated. This definitely
indicates that output is not line-buffered and that could mean that
it in fact fails multiple lines later (processing triggers or any
such thing) but that the successful operations were not properly
logged. At this point I guess it's the apt-get utility which does

Indeed it's still not fixed on Travis' side. However what Ilya did
actually worked, in that the status is not reported as a global
build failure anymore. This allows us to continue to monitor if
and when this issue finally resolves on the build infrastructure.
It's also possible that they're not aware of the problem due to
too few people using arm64. If someone has contacts there it might
be worth checking with them. All we know for now is that it seems
to stop moving while setting up libpcre2. Maybe there's a bug in

that's why it is marked as "allow to fail"

Re: [PATCH] fix errored ARM64 builds in travis-ci

[Martin Grigorov]

Hi,

I've just created a PR (https://github.com/haproxy/haproxy/pull/617/files)
that introduces testing on ARM64/AARCH64 at GitHub Actions.
It almost works! There are few tests that fail. Any help finding the reason
is very welcome!

Re: [PATCH] fix errored ARM64 builds in travis-ci

[Илья Шипицин]

Martin,

as the one of the most interested in ARM64 builds, I've got news for you


can you try

travis_wait 30 bash -c 'scripts/build-ssl.sh >build-ssl.log 2>&1' || (cat
build-ssl.log && exit 1)

in travis ? (please not "travis_wait 30" instead of "travis_wait")


also, it might be important to clear travis cache from time to time.
as for myself, "travis_wait 30" helped me to resolve similar issue on
another project (in my own fork haproxy on arm64 builds just fine)

Ilya,

The commit message is mandatory, we won't take your patches if you don't
make the effort to write it, could you add a little bit of explanation
there? For example you could explain what's the problem with travis,
link to a mailing thread where we discussed the problem etc.

Thanks!

well, there are several topics on travis-ci forum related to "output on

Let us disable ARM64 travis-ci builds for few months.

Martin, I'll play with hosted github runner in order to find a way how we
can limit its builds to allowed only.

Re: [PATCH] fix errored ARM64 builds in travis-ci

[Martin Grigorov]

Current master's build passed the problematic point in my TravisCI project:
https://travis-ci.org/github/martin-g/haproxy/jobs/663953359
Note: I use TravisCI .org while HAProxy's official project is at .com:
https://travis-ci.com/github/haproxy/haproxy
I also think this is a problem on TravisCI's end.

There is one major problem with GitHub Actions self hosted runners at the
moment - they are not really private.
I.e. if someone forks HAProxy and pushes something into their fork it will
trigger builds on your private node, i.e. it will consume its resources.
There is no way to say "this is my private node and I want it to build only
after commits in https://github.com/haproxy/haproxy";

If you find a way around this issue and you need an ARM64 VM then just let
me know!

Martin

yes, I still believe it is because of buffering. I might have missed

unless I will repair it, I'll drop arm64 support on travis (and we will

Yes, I believe Travis does, because "private variables" are disabled in
pull requests. Otherwise someone could just add `echo $PRIVATE_TOKEN` to
the configuration within their pull requests.

Of course one could also simply add their own repository to Travis to
test it out without the need for a pull request. In fact I believe Ilya
does: https://travis-ci.com/github/chipitsine/haproxy

https://github.com/haproxy/haproxy/pulls?q=is%3Apr+is%3Aclosed

GitHub Actions would need to be explicitly enabled for pull requests.

Ilya's fixes are correct, but apply at a later point in time.

Yes I agree here. Travis is getting more and more unreliable. GitHub
Actions which we are already using for Cygwin and recently for the spell
check supports amd64 using GitHub's runners and ARM using self-hosted
runners:
https://github.blog/changelog/2019-12-03-github-actions-self-hosted-runners-on-arm-architectures/

It might be a good replacement. Especially when using self hosted
runners, because then we are not restricted by some overcrowded cloud
infrastructure. Someone would need to step up to provide the runners,
though.

I'm also using it for my haproxy-auth-request Lua script and VTest:
https://github.com/TimWolla/haproxy-auth-request/blob/master/.github/workflows/vtest.yml

Well, maybe we could have a temporary branch to run the reg-tests then
merge this branch once the reg-tests pass. That's what CI guys does
generally.

Or people could just run the CI on their own fork before submitting the
patches, but I don't know how complex this is, and we will need some doc
if we doc that.

That was my first impression as well, but when seeing Ilya's fix I
thought I had incorrectly analysed the situation and that we were
just missing some part of the buffered output.

It's really annoying to have to constantly commits into the project
just to experiment with random fixes there. The problem could very
well be in the build-ssl script but it's hard to tell. I was thinking
about disabling this entry for now because it's a pain to constantly
see the build status in red while it's only the SSL build which fails,
something that's out of our scope.

The logs stop working during `apt` processing. This looks like an issue
on Travis' end to me. Maybe a bug report should be filed with their
support. It seems to consistently hang somewhere around the installation
of libpcre2.

So I could isolate the minimum code to reproduce the bug:

#include 

int nbt = 64;

struct srv {
void *a[5];
int **b;
};

void check_config_validity4(struct srv *srv, unsigned int *v)
{
int i;

for (i = 0; i < nbt; i++)
(*v)++;
 
srv->b = calloc(/*(unsigned int)*/nbt, sizeof(*srv->b));
for (i = 0; i < nbt; i++)
srv->b[i] = 0;
}

Just change the fields ordering in "struct srv" or the size of field "a"
and the bug disappears. Remove any of the loops or make it not depend on
nbt and the bug disappears. Casting nbt to unsigned has no effect. It
always emits the same warning as seen, and only on 32-bits.

When I have a bit of spare time I may file a bug to gcc with this excerpt,
unless someone wants to handle it, of course. Even once fixed it will
probably not flow down to distros given that it's not critical, so we'll
have to work around it as we can.

OK, I've put my hands on an ubuntu-18.04 + gcc8 32 bits. And now I can
confirm it definitely is a gcc bug. The code is the same as a few lines
above.  The cast was added a first time to shut it up but it re-appears.
And if you just change the condition in the "for" loop a few lines above
that *walks* through global.nbthread, the warning disappears. Gcc seems
to believe that we cannot reach that point if we enter the loop, which
is obviously wrong.

This is really annoying, so much time spent dealing with bogus warnings
is really irritating. I'm going to work around it with a cast to unsigned
short.

The worst part of it is that if it emits such a warning, who knows how valid
is the code that it will produce given that it doesn't even seem to figure
the code path :-(

because calloc multiplies the two fields and gcc decided that the largest
value we could possibly pass to the first one if we were as stupid as it
is is 2147483648. Interestingly it took the largest negative value turned
to positive and ignored the positive ones that can be turned to the second
half that are negative if nbthread was negative.

I really think this test is totally bogus and that there is no way to
express it correctly. I mean, gcc only lets us use 8, 16, 32 or 64 bits.
If you need to calloc a few megabytes, you'll be forced to apply a mask
to the value just to shut it up, and *create* the overflow problem yourself
when it didn't exist.

Let's give up on this one if it doesn't cause too much trouble to you.
Otherwise we might cheat doing this :

calloc((unsigned short)global.nbthread, ...)

But I really despise this given that we have to make the code wrong just
to please this shitty compiler.

That's essentially what the cast did. Also we don't do it because I think
I remember that we used to use value -1 to mean "unspecified" during the
parsing.

No, the reality is only about the possible extent of the value. By
turning it to unsigned it it would still be allowed to cover 0..2^32-1.
It turns out the compiler knows nothing about this value and just says
"if you did something wrong, it could theorically do that". That's
exactly the problem with this type of warnings, they're utter shit
because they assume the compiler knows better than the developer what
the possible range of his numbers are but the compiler doesn't even
look where the values are assigned and knows nothing, so it only relies
on types.

Anyway it's obvious that stupid gcc warnings started to appear after
gcc developers stopped using it for themselves by rewriting it in C++,
so they don't care if they piss off their users. Possibly some of them
don't even read C anymore since they don't need to :-/

Googling for that error message says something about the *result*
needing to fit into ptrdiff_t and also something about negative numbers.

Maybe it is sufficient to change `nbthread` from `int` to `unsigned
int`? Otherwise the compiler assumes that a negative nbthread casted to
an unsigned value becomes too large. I didn't check whether the code
assumes that nbthread can be negative anywhere.

Thanks for the test! So basically this clearly proves we respect the
calling convention but the compiler still complains. OK I'm seeing in
the mad that it's for functions "decorated" with the "alloc_size"
attribute. Thus in short they enforce constraints that cannot be
expressed with available types. This is becoming totally ridiculous.

We're getting a huge collection of stupid warnings to shut up. I
suspect that the sum of all the code written to shut them is larger
than what haproxy 1.0 used to be :-/

The man page says we can disable this crap using
-Walloc-size-larger-than=SIZE_MAX but on my compiler (8.2) it simply
fails to build. However when passing explicit values not even that
large, I don't get any such warning, so I'm starting to think that
it's a real bug of GCC 9.2, because quite frankly, aside calling
calloc() with a char or short in argument, there's almost no way out
of this absurdity.

For me, calling it with -Walloc-size-larger-than=-1 makes it stay
silent. is it also the case for you ? You can patch your Makefile this
way:

diff --git a/Makefile b/Makefile
index 8399f6ca35..4757bc77e6 100644
--- a/Makefile
+++ b/Makefile

If it still fails, we'll have to ignore it and wait for this monstrosity

Yes definitely. You just have to add "ERR=1" to your "make" command line
and it will append -Werror. I do this on my builds as well. And I agree
it will save some time because quite frankly, analysing why a regtest
failed when we already have a build warning is pointless!

yep.
I'll play with it a liitle bit, and hopefully we will add cross builds to
Github Actions.


also, can we treat warnings as errors for CI builds ? it would save a bunch
of time, instead of
looking at build log, we can watch for build status.

So for those not seeing the screenshot, it says:
warning: argument 1 range [2147483648, 4294967295] exceeds maximum object
size 2147483647 :

 new->idle_orphan_conns = calloc((unsigned int)global.nbthread, 
sizeof(*new->idle_orphan_conns));

Thus the cast to unsigned int was likely placed there to shut it up
once. Looking at the man page, it says:

   void *calloc(size_t nmemb, size_t size);

size_t is unsigned (unless you're using an older gcc < 2.4 on a unusual
OS). I don't see how it can be said to have a maximum size of 2147483647.

This is exactly the type of stupid warnings that causes us to add casts
that hide real bugs :-/

Could you please try to use (size_t) instead of (unsigned int) ? If it's
enough to shut it up, I'm fine with doing that change. Otherwise we'll
probably get rid of that stupid warning.

Thanks!

It's not the case for me but I had to add it for another one, I think
it was for the mips running in my build farm's controller. It's easy
to detect usually, if the linking fails with atomic operations you
know you need it.

Then don't bother with this, it's likely then that they will not
have all the environment available. Maybe even their hardware does
not support arm32 at all. It was just a suggestion to try to optimize
the solution but even arm64 is already nice to have.

> is it common way to use cross build for building haproxy ?

Yes it is. Actually I don't think I've built it natively for a very
long time now, as even on my laptop I'm used to stick to the cross-
compilers which are distributed on the distcc build farm running on
the lab load generators :-)

In practice just pass "CC=/path/to/gcc" and let it do its job. It will
automatically use LD=$(CC) if you don't override it. You may have to
pass PCRE_INC/PCRE_LIB, SSL_INC/SSL_LIB, LUA_INC/LUA_LIB but that's
about all.

Just for reference here's the command line I'm using when building
(and a variant with -O0 which builds in 3.5 seconds). It may look
large because I force all debugging options but it's in a script so
I don't have to type it :-)

When testing with various local openssl branches I do have another variant
of this which uses the local, native pre-processor and linkers, and remote
compilers. It's a bit ugly since they're not on the same version but in
practice it works fine.

Ah that's interesting! I frequently build for arm/arm64 but I agree
it would be nice to have this done more frequently. The two main points
I'm seeing are :
  - unsigned chars, which occasionally trigger a warning somewhere
  - non-x86 build, which can occasionally trigger a build error if
we accidently rely on an arch-specific function

In fact I would even suggest that we build for arm instead of arm64 so
that we switch to 32 bits at the same time and have an opportunity to
detect long vs int vs uint64t vs pointer vs size_t issues (typically
places where printf uses "%lu" without a cast for uint64_t).

Ah that's interesting! I frequently build for arm/arm64 but I agree
it would be nice to have this done more frequently. The two main points
I'm seeing are :
  - unsigned chars, which occasionally trigger a warning somewhere
  - non-x86 build, which can occasionally trigger a build error if
