[v3] [RFC] Merge meta-rust to oe-core

[v3] [RFC] Merge meta-rust to oe-core

[Randy MacLeod]

I started working on the merge of meta-rust to oe-core again.

CCing widely at the beginning this time.
Please reply to me privately if you want to be dropped.

I really need other people to sign up as [co-]maintainers!

I pushed what I did today to:
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=rmacleod/rust-redo-aug-10-2021-a

$ git log --stat below.

I've only started but so far, what I see is that, as expected, 
rust-hello-world works for
qemux86-64, qemuarm and likely other targets. I'm doing a buildall-qemu 
overnight.

The oe-selftests that we had problems with before are still a problem:

oe-selftest still has at least three tests failing:

1.
oe-selftest -r distrodata.Distrodata.test_maintainers
   This is due having two versions of cargo and rust.

   --> I'll remove 1.51 unless people object.

2.
oe-selftest -r sstatetests.SStateTests.test_sstate_noop_samesigs
oe-selftest -r sstatetests.SStateTests.test_sstate_sametune_samesigs

I've just started to look at these test failures.
$ bitbake-dump-sigs shows a diff like:

  List of dependencies for variable BASEDEPENDS is set()
  List of dependencies for variable BUILD_AR is {'BUILD_PREFIX'}
-List of dependencies for variable BUILD_AS is {'BUILD_PREFIX', 'BUILD_AS_ARCH'}
+List of dependencies for variable BUILD_AS is {'BUILD_AS_ARCH', 'BUILD_PREFIX'}
  List of dependencies for variable BUILD_AS_ARCH is set()
-List of dependencies for variable BUILD_CC is {'BUILD_PREFIX', 'BUILD_CC_ARCH'}
-List of dependencies for variable BUILD_CCLD is {'BUILD_PREFIX', 'BUILD_CC_ARCH'}
+List of dependencies for variable BUILD_CC is {'BUILD_CC_ARCH', 'BUILD_PREFIX'}
+List of dependencies for variable BUILD_CCLD is {'BUILD_CC_ARCH', 'BUILD_PREFIX'}
  List of dependencies for variable BUILD_CC_ARCH is set()

Tips welcome!
  

Btw, I know that the rust community is working on reproducibility:
    https://github.com/rust-lang/rust/labels/A-reproducibility
This diffsigs problem may be related but I haven't looked at the issue long enough yet to tell.


4.
I'll run a test on the autobuilder to see if the debian build from Feb is still a problem:
   rust-native doesn't build on debian8:
https://autobuilder.yoctoproject.org/typhoon/#/builders/116/builds/40/steps/13/logs/stdio


I'll run buildall-qemu rust-hello-world overnight.

Thanks,

../Randy

Results below.

Vinay or I will look into glibc/qemuppc64
if no one else is working on that.

The musl build failures are all alike with the error shown below.
Has anyone see that before?

[OE-core] [v4] [RFC] Merge meta-rust to oe-core

[Vinay Kumar]

rust-common.inc: Fix build failure with qemuppc64.

The glibc build of "rust-hello-world" throws error in libstd-rs package.
error: unrecognized arch "powerpc64le" in target specification

The same got fixed by changing the arch to "powerpc64".

Hi Randy,

>> Vinay or I will look into glibc/qemuppc64
>> if no one else is working on that.

The failure is due to the below error in libstd-rs package build.
"error: unrecognized arch "powerpc64le" in target specification"

The reason for this is "arch": "powerpc64le" from the below target
specific file.

cat $b2/tmp/work/ppc64p9le-poky-linux/libstd-rs/1.54.0-r0/recipe-sysroot-native/usr/lib/rustlib/powerpc64le-poky-linux.json
{
    "llvm-target": "powerpc64le-unknown-linux-gnu",
    "data-layout": "e-m:e-i64:64-n32:64-v256:256:256-v512:512:512",
    "max-atomic-width": 64,
    "target-pointer-width": "64",
    "target-c-int-width": "64",
    "target-endian": "little",
    "arch": "powerpc64le",
    "os": "linux",
    "env": "gnu",
    "vendor": "unknown",
    "target-family": "unix",
    "linker": "powerpc64le-poky-linux-gcc",
    "ar": "powerpc64le-poky-linux-ar",
    "cpu": "generic",
    "dynamic-linking": true,
    "executables": true,
    "linker-is-gnu": true,
    "linker-flavor": "gcc",
    "has-rpath": true,
    "has-elf-tls": true,
    "position-independent-executables": true,
    "panic-strategy": "unwind"
}

So the "arch" should be "powerpc64" in case of "powerpc64le" fixes the
librstd-rs build failure.

With the above fix,

Thanks Vinay, applied.

I'll push a new branch to poky-contrib later today.

Re: [OE-core] [v4] [RFC] Merge meta-rust to oe-core - Aug 19 update

[Randy MacLeod]

[-- Attachment #1: Type: text/plain, Size: 6472 bytes --]

Added Trevor who may be working on upgrading python-cryptography.
Added Anatol since he was interested last time we worked on merging.

Again, let me know if you want to be dropped by replying privately.
No one from the meta-rust community responded last time so I'm
assuming that y'all are just on vacation! ;-)

I fixed and worked-around a few issues and pushed a new branch:

 
http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=rmacleod/rust-redo-aug-17-2021-a

1. There are only a few new commits including Vinay's:

    757da4cbf1e rust: remove Rust version 1.51.0 toolchain

    a4808f787ca cargo_common: remove http_proxy

    b6941135c00 rust-common.inc: Fix build failure with qemuppc64.


If anyone wants to help by doing test builds, trying to generate and use

and SDK with rust in it or anything else, that'd be great.



Alex also ran a test build on the Autobuilder:

    https://autobuilder.yoctoproject.org/typhoon/#/builders/83/builds/2439



but I have yet to look at the failed stages in the run.


Testing logs and debugging notes below for those interested.

../Randy



The test:
    oe-selftest -r distrodata.Distrodata.test_maintainers


is fixed by creating maintainer records for all rusty packages
and by removing the older version of the rust toolchain:
    757da4cbf1e rust: remove Rust version 1.51.0 toolchain



I suppose that if the meta-rust users want to keep an older TC
it can live in meta-rust.

Then, these tests:

    oe-selftest -r sstatetests.SStateTests.test_sstate_noop_samesigs

    oe-selftest -r sstatetests.SStateTests.test_sstate_sametune_samesigs


were failing. One issue was fixed by the work-around of:

    a4808f787ca cargo_common: remove http_proxy


Debugging the next step was a challenge since I hadn't worked
with diffsigs before. Then to simplify, I removed all rusty .bb package
    ( by mv foo.bb foo.bb.hide)
until I was down to the first recipe in the dependency tree:

    rust-llvm-native.

and then running:
   oe-selftest -r sstatetests.SStateTests.test_sstate_noop_samesigs \
                  sstatetests.SStateTests.test_sstate_sametune_samesigs \



2021-08-19 17:54:12,878 - oe-selftest - INFO

- oe-selftest () - Ran 2 tests in 142.012s

adding the next self consistent group of package:
    cargo/cargo-cross-canadian_1.54.0.bb

    cargo/cargo_1.54.0.bb

    rust/libstd-rs_1.54.0.bb

    rust/rust-cross-canadian_1.54.0.bb

    rust/rust-cross_1.54.0.bb

    rust/rust-tools-cross-canadian_1.54.0.bb

    rust/rust_1.54.0.bb



I see another http_proxy failure that seems to require a feature
drop in cargo:
 
https://github.com/rust-lang/cargo/blob/master/src/cargo/ops/registry.rs#L524

Patching out a feature doesn't seem like a good idea but
maybe someone else has a better one?

To see if there were other problems lurking menacingly behind the proxy
error, I disabled the http_proxy test in:
	meta/lib/oeqa/selftest/cases/sstatetests.py


    -http_proxy = "http://example.com/"

    +http_proxy = ""


and ran again to find:

- RESULTS - sstatetests.SStateTests.test_sstate_noop_samesigs:
       PASSED (50.63s)
- RESULTS - sstatetests.SStateTests.test_sstate_sametune_samesigs:
       FAILED (160.05s)

so that's somewhat encouraging but there is still the error:

      File ".../meta/lib/oeqa/selftest/cases/sstatetests.py", line 449,
    in test_sstate_sametune_samesigs

      self.assertCountEqual(files1, files2)

... lots of similar lines of diffsig info ...


Hacking the test to not clean up and
running bitbake-dumpsigs on the two sig files for the first error,
I get the two files attached. I also attached the
    tmp/log/oe-selftest-results.log file.

That's it for now.

I think I've gotten to the bottom of a chain of sigs that differ in part 
due to:
"Hash for dependent task" differing and found that on leaf node is:

stamps/x86_64-linux/rust-cross-i686/1.54.0-r0.do_rust_gen_target

See below for my notes and my assertion/question about the next step needing
to be deterministically ordering the elements used in rust_gen_target.

I did learn a bit about this test code that is failing:

https://git.openembedded.org/openembedded-core/tree/meta/lib/oeqa/selftest/cases/sstatetests.py#n404

as the comment explains:

|

The sstate checksums of two identical machines (using the same tune) 
should be the
same, apart from changes within the machine specific stamps directory. 
We use the
qemux86copy machine to test this. Also include multilibs in the test.|

so the good news is that there are: 23185files being checked and
only 43 are different and if you look at what packages and arches
differ it's:

x86_64-linux/lib32-rust-cross-i686
x86_64-linux/rust-cross-i686
core2-32-poky-linux/rust
core2-32-poky-linux/libstd-rs
x86-pokymllib32-linux/lib32-libstd-rs
x86-pokymllib32-linux/lib32-rust

Note that these are all 32bit multilib builds.
Maybe that's not so important for the initial merge to oe-core... Richard?


Looking at core2-32-poky-linux/rust the stages that have different 
signatures are:

do_configure
do_populate_sysroot
do_package_qa
do_install
do_package
do_packagedata
do_compile
do_prepare_recipe_sysroot
do_package_write_rpm

9 of the 19 stages. Ok so maybe it's not great news after all. ;-)


I'll kept digging down through the tree of dependant diffsigs
since when looking at do_prepare_recipe_sysroot, it was clear
that a key difference in it's signatures was due to:
   "Hash for dependent task ..."
differing. Finally I found a set of signatures that did not have a
diff in the dependent task:

stamps/x86_64-linux/rust-cross-i686/1.54.0-r0.do_rust_gen_target*

The simplified diff is below and the files are attached.

There are a variety of variables that differ only in order, such as:

-List of dependencies for variable TUNE_FEATURES is 
{'TUNE_FEATURES:tune-core2-32', 'DEFAULTTUNE'}
+List of dependencies for variable TUNE_FEATURES is {'DEFAULTTUNE', 
'TUNE_FEATURES:tune-core2-32'}

I assume the next step is to find out where those variables are produced:
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/tree/meta/recipes-devtools/rust/rust-common.inc?h=rmacleod/rust-redo-aug-10-2021-a#n292

and to introduce deterministic order when building them.

Re: [OE-core] [v4] [RFC] Merge meta-rust to oe-core - Aug 19 update

[Richard Purdie]

I had a look at this. I agree the output from the test isn't great so I:

oe-selftest -r sstatetests.SStateTests.test_sstate_noop_samesigs -j 1

then since you want to pick the earliest difference:

bitbake-diffsigs ../build-st-3665/tmp-sstatesamehash*/stamps/x86_64-linux/cargo-native/1.54.0-r0.do_configure.sigdata.*

since if a -native is differing, you'd start there. That reports:

Hash for dependent task cargo/cargo_1.54.0.bb:do_prepare_recipe_sysroot:virtual:native changed from 0eb4be5c1555696edece016e7497ed4b7a24ed1e601e4625187232b527ee9cbb to 6763576bba0c95e56b40093399df3f96ba386638f0bbe1cb405541f120128a92

so ok:

bitbake-diffsigs ../build-st-3665/tmp-sstatesamehash*/stamps/x86_64-linux/cargo-native/1.54.0-r0.do_prepare*.sigdata.*

Hash for dependent task rust/rust_1.54.0.bb:do_populate_sysroot:virtual:native changed from d0e0b66258d63cf6a75427dc8ee99f365edc2858087dd251924f533ead085237 to 5a7ea7762b43c59386f4f8914b98d17d4381f00f08685e429d22121157e3c58c

So rust-native comes before cargo-native. Lets try the earliest rust-native we can see:

bitbake-diffsigs ../build-st-3665/tmp-sstatesamehash*/stamps/x86_64-linux/rust-native/1.54.0-r0.do_configure*.sigdata.*
NOTE: Starting bitbake server...
basehash changed from d4562518270a3e161b7e4fef4c7b39a66ca6e32e3ae3612f4ae1623501701278 to 01cacaecd08c1d41745eaf981c5f8896d48faf755b596bfca62f52a4c35f4ea7
Variable http_proxy value changed from 'http://example.com/' to ''

So it still thinks http_proxy is an issue. Why?

bitbake-dumpsig ../build-st-3665/tmp-sstatesamehash/stamps/x86_64-linux/rust-native/1.54.0-r0.do_configure*.sigdata.* | grep http

i.e. the lines you commented out are still there. Bitbake's shell parser isn't
clever enough to know to ignore that.

If you delete the lines, things are much happier!

With a patch from Richard, and the http_proxy check removed,

$ git diff | grep "^[+-]"
--- a/meta/lib/oeqa/selftest/cases/sstatetests.py
+++ b/meta/lib/oeqa/selftest/cases/sstatetests.py
-http_proxy = "http://example.com/"
+http_proxy = ""

we have fixed the oe-selftest that was failing.
Any volunteers to stub out the http[s]_proxy code in cargo ?

I've written up a commit log that could use some review and pushed an 
update to:
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=rmacleod/rust-redo-aug-17-2021-a


I starting to work on the YP autobuilder issues.

I can build:
    $ bitbake cargo-cross-canadian-x86-64

Adding this:

require conf/multilib.conf
MULTILIBS = 'multilib:lib32'
DEFAULTTUNE:virtclass-multilib-lib32 = 'x86'

to my local.conf, I see that:

$ bitbake lib32-rust

fails with the error:
---
failed to execute command: 
"/ala-lpggp31/rmacleod/src/distro/yocto/b/aug-19-a/tmp/work/x86-pokymllib32-linux/lib32-rust/1.54.0-r0/lib32-recipe-sysroot/usr/lib/llvm-rust/bin/llvm-config" 
"--bindir"

---

Khem, a MUSL build fails:

$ TCLIBC=musl  bitbake rust-hello-world
as shown below (1) but I'll see if that's reproducible with a clean build.


I've also rebased to poky master:
   3fd2dff4eb3 (origin/master, origin/HEAD, master) ref-manual: Fix 
reference to bbappend section of dev-manual
and the two key oe-selftests still pass with the http_proxy work-around
as does core-image-minimal+rust-hello-world (2) so I've pushed a new 
branch:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=rmacleod/rust-redo-aug-21-2021-a


Richard, Alex,

I'm not sure you need to change cargo, I think if you remove the bit in the
bbclass that injects http_proxy, the tests are ok. That will perhaps break
anyone using proxies but for now, I think that is a reasonable step of getting
this moved forward?

I think there is one selftest issue left which is a multilib one.

Cheers,

Richard

That's what I hoped for as well but not what my testing showed.

I removed (commented out actually) the http_proxy injection here:
 
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=rmacleod/rust-redo-aug-17-2021-a&id=a4808f787caf8d0b44cf3946cf204164f24f91d4

but the test still fails unless I mangle the test:

    meta/lib/oeqa/selftest/cases/sstatetests.py


    -http_proxy = "http://example.com/"


    +http_proxy = ""

Right, my point is that doesn't remove it. You need to delete it, not comment it
out.

The issue is that bitbake does variable expansion on the scripts before running
them.

It can't tell that this is a comment, just that the script differs after
variable expansion.

Cheers,

Richard

Add Steven Walter in hopes that he or someone else
who uses meta-rust will help out.

Richard has fixed several new issues and is testing this in master-next:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=master-next

using the YP autobuilder.

We're seeing some odd intermittent build failures especially when using
the uninative class (used by default in poky) perhaps on older hosts but
we're not 100% sure of that correlation yet. See below and:

https://autobuilder.yoctoproject.org/typhoon/#/builders/116/builds/581/steps/13/logs/stdio

If we can't get this fixed in the next day or two, we'll miss the fall 
release.

Thanks to Richard's dogged determination and Herculean efforts,
the Rust recipes are now merged to the oe-core master branch.

    https://git.openembedded.org/openembedded-core/log/?qt=range&q=master


There are still some known problems, such as:

1. Tim Orling finding that Rust fails to build python-cryptography:

 
https://git.openembedded.org/meta-openembedded-contrib/log/?h=timo/rust_python3-cryptography

Tim says that this change helps:
 
https://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=timo/rustc-print-cfg-fix


and:

2. a reproducible build failure on CentOS-7:

    https://autobuilder.yoctoproject.org/typhoon/#/builders/115/builds/597

where, we see:
    = note: /bin/sh: /lib64/libc.so.6: version `GLIBC_2.33' \

    /home/pokybuild/yocto-worker/reproducible-centos/build/\

Please test, send patches and/or let me know about any other problems by
email or by opening  a defect in the YP bugzilla:
    https://bugzilla.yoctoproject.org/


I'll work on a commit for meta-rust to remove the components
that have been moved to oe-core. I'm not sure what the
meta-rust developers and users want to do as far as what will
remain in meta-rust but the short list that I have so far is:
1. scripts
2. Jenkins tests
3. Rust version 1.51.0 ?

I had a quick look at this. It reproduces if you build cargo-native on a centos7
machine with our M2 buildtools tarball in the environment of the build.

Adding the uninative relocation hack to the cargo snapshot binary with:

 do_cargo_setup_snapshot () {
        ${WORKDIR}/rust-snapshot-components/${CARGO_SNAPSHOT}/install.sh --prefix="${WORKDIR}/${CARGO_SNAPSHOT}" --disable-ldconfig
+       # Need to use uninative's loader if enabled/present since the library paths
+       # are used internally by rust and result in symbol mismatches if we don't
+       if [ ! -z "${UNINATIVE_LOADER}" -a -e "${UNINATIVE_LOADER}" ]; then
+               patchelf-uninative ${WORKDIR}/${CARGO_SNAPSHOT}/bin/cargo --set-interpreter ${UNINATIVE_LOADER}
+       fi
 }

didn't help.

Running the command it mentions failing by hand in the same toolchain enabled
shell works. It therefore seems likely that something rust is putting into the
environment is breaking things. What that is, I don't know, I'm out of time to
debug further.

It looks to me like it is using the ld from the host instead of the buildtools
tarball. I did change tmp/work/x86_64-linux/cargo-native/1.54.0-
r0/wrapper/target-rust-ccld to a full path to gcc and messed with PATH to ensure
it would find "our" ld first but that didn't help.

In the error output is some:

Usage: which [options] [--] COMMAND [...]
Write the full path of COMMAND(s) to standard output.

suggesting some which call might not be compatible with centos7?

Cheers,

Richard

With some further debugging as I mentioned in my other reply, it is the
LD_LIBRARY_PATH setting which is confusing things. Probably as a result of:

https://doc.rust-lang.org/cargo/reference/environment-variables.html#dynamic-library-paths

It is a bit more subtle than that. The ccld script has /bin/sh as the
interpreter which uses the host libc and host libtinfo. The LD_LIBRARY_PATH
injected by cargo causes it to find the libtinfo in the recipe-sysroot-native
which is incompatible with it and things then fail :(.

This is the first time we've tried this as far as I know.

It is a horrible mix of different host tools and libcs from uninative,
buildtools and the host all conflicting when LD_LIBRARY_PATH is set :(.

I'm not sure how to go about resolving this.

I noticed some code in cargo. I think the code is where the sysroot path is
injected. Since rust figures out its own paths to everything it is a little
surprising this is needed and the comment suggests the author had similar
thoughts. I therefore tried the following patch:

Index: cargo/src/cargo/core/compiler/compilation.rs
===================================================================
--- cargo.orig/src/cargo/core/compiler/compilation.rs
+++ cargo/src/cargo/core/compiler/compilation.rs
@@ -273,13 +273,6 @@ impl<'cfg> Compilation<'cfg> {
             ));
             search_path.push(self.deps_output[&kind].clone());
             search_path.push(self.root_output[&kind].clone());
-            // For build-std, we don't want to accidentally pull in any shared
-            // libs from the sysroot that ships with rustc. This may not be
-            // required (at least I cannot craft a situation where it
-            // matters), but is here to be safe.
-            if self.config.cli_unstable().build_std.is_none() {
-                search_path.push(self.sysroot_target_libdir[&kind].clone());
-            }
         }
 
         let dylib_path = paths::dylib_path();

however since I think we're running a prebuilt binary rather than the one we're
building, this does work. I'm therefore not sure how we can fix this. Is this
code something upstream might consider removing?

Cheers,

Richard

temp/run.do_compile:	bbnote "cargo = $(which /home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp2/work/x86_64-linux/cargo-native/1.54.0-r0/cargo-1.53.0-x86_64-unknown-linux-gnu/bin/cargo)"
temp/run.do_compile:	bbnote "rustc = $(which ${RUSTC})"

so probably not important.

Distilling through all the noise, we reach this test case:

where you:

a) install buildtools-tarball and source the buildtools env
b) build cargo-native

then the failure can be reproduced with something like:

[pokybuild@centos7-ty-4 build-st]$ LD_LIBRARY_PATH=/home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp/work/x86_64-linux/cargo-native/1.54.0-r0/recipe-sysroot-native/usr/lib /home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp/work/x86_64-linux/cargo-native/1.54.0-r0/wrapper/target-rust-ccld
/bin/sh: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp/work/x86_64-linux/cargo-native/1.54.0-r0/recipe-sysroot-native/usr/lib/libtinfo.so.5)

which is because /bin/sh comes from the host and links against libtinfo,
LD_LIBRARY_PATH is set by cargo to the recipe sysroot, it finds our libtinfo
rather than the host one and it is incompatible with the libc/loader being used
by /bin/sh.

I did find this is documented in: 

https://doc.rust-lang.org/cargo/reference/environment-variables.html#dynamic-library-paths

and I suspect this is because it is adding "the rustc sysroot library path".

This also explains why running the reported ccld command by hand works since the
LD_LIBRARY_PATH is no longer set.

How to fix this? No idea.

Could/should we make rust use a different sysroot location?

Cheers,

Richard

With the patch below, this branch now builds the latest
pyhton3-cryptography 3.4.8. There are some ptest warnings and errors that
are still in progress. Also the recipes in this branch need a final scrub
before submitting.

Happy to have anyone test the branch if you use python3-cryptography.

Ignore me on this last bit, its other local stuff corrupting my test, sorry for
the noise.
