[bug] Build of a recipe which has a tool_requires with `<host_version>` may fail if build triggered from build context

SpaceIm commented 1 year ago

Environment details

Operating System+version: Ubuntu 22.04
Compiler+version: GCC 12
Conan version: 2.0.13
Python version: 3.10.5

Steps to reproduce

For example you could add qt recipe to build requirements of a recipe on Linux, it will drag xkbcommon in build context. Also take care of not downloading pre-built binaries from conancenter but build from source, and do not have xkbcommon in host context (or a different flavor like shared=True). Build of xkbcommon will fail (It was working fine before https://github.com/conan-io/conan-center-index/pull/19983 which has replaced wayland/1.21.0 by wayland/<host_version> in its build requirements).

If you build xkbcommon with a simple conan install --requires xkbcommon/1.5.0 -b, it works fine.

It might be an issue with PkgConfigDeps build_context_activated with <host_version in the context of a build triggered from build context, I don't know: https://github.com/conan-io/conan-center-index/blob/8d3eb5dcf5fcf29d971892e156781b5e26e1453a/recipes/xkbcommon/all/conanfile.py#L104-L138

memsharded commented 1 year ago

Thanks for reporting.

If the <host_version> is being resolved to a real version and it matches the correct one, then this doesn't seem related? So maybe this fail is because of that specific package being built as a dependency, not because of the <host_version> things.

I cannot reproduce this at the moment, this package doesn't work in Windows, and I don't have linux right now. It would be great to have some minimal reproducible case.

SpaceIm commented 1 year ago

Is there not some hidden bug? Sure it resolves to the correct version, but the build fails because it seems to be slightly different than the same build triggered from host context (this one succeeds), and it shouldn't because I have exactly the same profile in host & build context. This is why I suspect a bug when a build is triggered from build context. And because the same build was working fine before this <host_version>, yes I suspect something related.

It's hard to provide a reproducible example except using current RREV of xkbcommon in conancenter. The best I can do is to provide a diff of all files generated in conan folder of build folder, between a regular build of xbkcommon with conan install --requires xkbcommon, and an "indirect build" of xkbcommon from build context (with host & build profiles identical). If the diff is not null, there is a bug. It wouldn't be the first time (I don't find previous issue, but I remember an old bug of builds from build context).

SpaceIm commented 1 year ago

If you are on Windows, you can build xkbcommon in WSL.

Step 1: Check that it builds fine with a regular installation:

conan install --requires xkbcommon/1.5.0 -b xkbcommon -b missing

Step 2: check that it fails if build is triggered from build context. These commands may be sufficient:

conan remove xkbcommon/1.5.0 -c
conan install --tool-requires xkbcommon/1.5.0 -b xkbcommon -b missing

Since host & build profile are the same, the second build should be exactly the same, but it fails.

memsharded commented 1 year ago

It seems to work fine in Conan 2.0.13 in WSL:

conan remove "*" -c
conan install --tool-requires xkbcommon/1.5.0 -b xkbcommon
....
cli: Generated aggregated env files: ['conanbuild.sh', 'conanrun.sh']
Install finished successfully

@memsharded I've also ran into this exact issue using Conan V1.

../src/meson.build:481:12: ERROR: Problem encountered: The Wayland xkbcli programs require wayland-client >= 1.2.0, wayland-protocols >= 1.7 which were not found.
You can disable the Wayland xkbcli programs with -Denable-wayland=false.

SpaceIm commented 1 year ago

Yep conan install --tool-requires xkbcommon/1.5.0 -b xkbcommon -b missing may not be enough to reproduce this issue. Try to add xkbcommon to dependencies of a recipe which is a build requirement of another recipe.

ericLemanissier commented 1 year ago

It seems more probable that this is a bug in xkbcommon than in conan itself, considering the recipes does some different actions at 5 different steps, depending on if there is a build profile or not : https://github.com/search?q=repo%3Aconan-io%2Fconan-center-index+_has_build_profile+path%3A%2F%5Erecipes%5C%2Fxkbcommon%5C%2Fall%5C%2F%2F&type=code

I've definitely had the same thought, and finally opened issue #14935 to try to simplify this kind of thing, which I should have done a long time ago.

SpaceIm commented 10 months ago

Still broken in conan 2.0.15

It's not a recipe issue, otherwise why it doesn't fail with conan install --requires xkbcommon/1.6.0, but fails if you build let's say a recipe depending on qt in build requirements (dragging indirectly xkbcommon in build context), like qwt with all shared in host context, but static in build context?

memsharded commented 10 months ago

A couple of summary points here:

This seems more related to PkgConfigDeps than to the <host_version>, but this needs to be checked
It would still be necessary a minimal way to reproduce it, preferably without bringing qt or other huge packages there, to reduce the area. If the issue comes because something is a tool-requires of something, then a 5 lines recipe with that requirement should help to reproduce it.

jwillikers commented 9 months ago

I think you can create a minimal example by creating a simple Conan package for a command-line tool that depends on xkbcommon. Then, add a test a package to run the tool as a tool_requires and you should get the error. I hit this issue in conan-io/conan-center-index#22412.

memsharded commented 9 months ago

Thanks for the feedback @jwillikers

I have just tried exactly what you propose with latest Conan 2.0.17 and it works fine, I cannot make it fail.

This is why I say that we need something minimal (that is still far from minimal, for a start it only works in Linux, so I cannot test things in my default system which is Windows) to reproduce, like exact steps and commands, even including docker images (I tried using the conanio/gcc11 docker image)

jwillikers commented 9 months ago

I forgot to mention that you have to have the option xkbcommon/*:with_wayland=True.

memsharded commented 9 months ago

I forgot to mention that you have to have the option xkbcommon/*:with_wayland=True

Still the same, it seems to work.

@memsharded Thanks for looking into this. I'll work on getting a minimal example of the issue when I get time, though I haven't checked if the problem occurs with Conan v2 yet.

Got same wayland errors during Conan v2 install with self.requires("qt/6.6.1"), -s build_type=Debug and -o *:shared=True in conanfile (Ubuntu):

conan install . --profile:build=changeme_profile --profile:host=changeme_profile -c tools.system.package_manager:mode=install -c tools.system.package_manager:sudo=True --build=missing -o :shared=True -o abseil:shared=False -o boost:shared=True -o qt:shared=True -c tools.build:verbosity=verbose -c tools.build:jobs=4 -s compiler.cppstd=gnu17 -c tools.build:skip_test=True -s build_type=Debug

NOTE: I had to also add "qt/6.6.1" to tool_requires due to $env:PATH without QT paths after .\build\generators\conanbuild.ps1 i.e. without moc.exe on windows (probably separate bug) self.tool_requires("qt/6.6.1") # moc.exe requires to set$env:QT_PLUGIN_PATH,$env:QT_HOST_PATH, `$env:PATH```

Thanks for the details.

I have tried it, had to change:

  def set_version(self):
    self.version = "1.0"

Then, after that, with the command:

conan install . -c tools.system.package_manager:mode=install -c tools.system.package_manager:sudo=True --build=missing -o "*:shared=True" -o "abseil/*:shared=False" -o "boost*:shared=True" -o qt*:shared=True -c tools.build:verbosity=verbose -c tools.build:jobs=4 -s compiler.cppstd=gnu17 -c tools.build:skip_test=True -s build_type=Debug

I had to quote the "*".

Then I got a normal conflict:

ERROR: Version conflict: wayland/1.22.0->expat/2.5.0, ->expat/2.6.0.

Not the error you are reporting inside the Meson build. Testing with latest Conan 2.1.

Then I used the new 2.1 to resolve the conflict:

[replace_requires]
expat/*: expat/2.6.0

and pass it both as host and build profile

Then it started to build things, but then I got stuck with:

libelf/0.8.13: WARN: network: Error downloading file http://repository.timesys.com/buildsources/l/libelf/libelf-0.8.13/libelf-0.8.13.tar.gz: 'HTTPConnectionPool(host='repository.timesys.com', port=80): Max retries exceeded with url: /buildsources/l/libelf/libelf-0.8.13/libelf-0.8.13.tar.gz (Caused by ResponseError('too many 504 error responses'))'

It seems their server is down at this moment

It eventually proceed. Then I wanted to introduce some prints/traces in the xkbcommon recipe, but then the latest revisions from ConanCenter brought a new version conflict, I added a new replace:

libxml2/*: libxml2/2.12.3

to be able to move forward.

I now think that I have been able to identify the issue in PkgConfigDeps, I will be working on a fix for Conan 2.2. Sorry it took so long, it was challenging to reproduce.

Submitting a fix in https://github.com/conan-io/conan/pull/15763

The fix was quick once we could reproduce it. This highlights the importance of reducing to the very minimum the repro-cases, it helps a lot to expedite the resolution of bugs.

I have already tried to backport this to Conan 1.X, but it doesn't seem possible, as the graph model (tool_requires when you are already in the build context) in Conan 1.X does not correctly support this case.

Thanks all for the feedback!
