Re: Orphaning python-flit
I patched python-signature-dispatch[1] and python-vecrec[2] so that they now use flit-core. I’m glad you pointed out that they were using flit.

It makes a lot of sense also if you think about it this way: - packaging needs a solid base - developers and (typical fedora) users want the latest and greatest A split like in this case gives us both. I have the impression that we package way too much stuff which would be installed better on a per user base, such as many python and rust and go (and ...) packages and fonts. This leads to many interesting discussions and decisions about what kind of upgrade is right on Fedora and even EPEL.

python-flit updated to 3.0.0
Hello everyone, python-flit was updated to version 3.0.0 in rawhide. Flit now requires metadata in pyproject.toml file instead of flit.init. We have fixed 2 Fedora packages affected by this change so there is no action needed from your side. This is just a heads up in case you will use Flit in the future. See the full changelog at https://flit.readthedocs.io/en/latest/history.html#version-3-0. Have a nice day.

Ah, OK - this makes sense. Framing it in terms of the required input file, the two most suitable names would be: * "pyproject.toml compatible spec files" * "setup.py only spec files" I'd suggest keeping the current wheel-centric macro names, though, and just adjust the wheel building macro to accept pyproject.toml files in addition to setup.py files. >> At a policy management level, I think it makes sense to separate the >> "these are the policy decisions you *must* abide by" guidelines (which >> are the domain of FPC) from the "Here are the helper macros that we >> provide to make it easier to abide by those guidelines".

In that case, I'd lean towards emphasising the macros in the guidelines, and then pointing towards the macro definitions in dist-git if folks really want to dig into the details of what the macros actually do. However, we'd also keep the various sections that explain how to do various lower level things correctly (like precompiling Python files), since those providing the "Why?" of various decisions, which simply reading the macro source files won't give you.

I leaned towards spelling out the manual steps and then showing that there were macros that encapsulated some of those steps but that may no longer be the preferred direction. The guidelines must have at least one or the other, though.

Yes, those are both unchanged. The issue is specifically with the example in https://fedoraproject.org/wiki/Packaging:Python#Example_common_spec_file, which only shows the %pyX_build and %pyX_install macros, which assume that the right way to install a Python project inside the buildroot is to run: "setup.py build" in the %build step "setup.py install" in the %install step That works as long as the project either uses setup.py natively (i.e. distutils/setuptools projects), or provides a backwards compatibility shim, but won't work consistently for newer projects that rely on pyproject.toml and the static build dependency declarations from PEPs 517 & 518. Switching to a wheel based build doesn't change either the starting point (which is still an sdist) or the end point (which is still a policy compliant RPM), it changes the internal interface between the build step and the install step from being a distutils build directory to a wheel archive: "pip wheel" (or "setup.py bdist_wheel") in the %build step "pip install" in the %install step At a policy management level, I think it makes sense to separate the "these are the policy decisions you *must* abide by" guidelines (which are the domain of FPC) from the "Here are the helper macros that we provide to make it easier to abide by those guidelines". The distinction is that you can still pass a package review without using the helper macros, but you'll still want to use them in most cases simply because they make ongoing package maintenance easier (since the helper macros will adjust automatically to rebases and policy changes, while handcrafted spec files might not).

I must be further outside of the packaging loop than I thought. The two questions that I need to know the answer to to make sure we're even vaguley on the same page are: * Is the rpm Source: line still going to be an sdist? * Are the files that are in the built rpm going to be the same as now? -Toshio ___ python-devel mailing list -- python-devel@lists.fedoraproject.org To unsubscribe send an email to python-devel-le...@lists.fedoraproject.org

That way, the update to the guidelines page can just be a link to a page maintained in https://github.com/fedora-python/fedora-python Cheers, Nick. P.S. The latter page is mainly in GitHub because I couldn't figure out how to get Pagure's RTD integration to work, but I also see some benefits in lowering barriers to contribution for Python folks that already have GitHub accounts, but don't have Fedora accounts yet. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia ___ python-devel mailing list -- python-devel@lists.fedoraproject.org To unsubscribe send an email to python-devel-le...@lists.fedoraproject.org

I think it's reasonable to document macros which are going to need to use. Python packaging just isn't sufficiently regularized (or simple) that people can avoid having to come into more "intimate" contact with the macros. That documentation doesn't really have to be in the guidelines page, of course, and we could certainly move them out to a separate document. (We recommend but don't document %autosetup, for example. There's plenty of stuff you have to search for, which is unfortunate.) Currently we have them in a list that's collapsed by default so at least they don't take up too much space on the page. Note also that the guidelines are in the wiki for convenience, but there have been at least two efforts to move them to a "better" format. And I would truly love to have a companion set of documents which aren't guidelines but which expand on them and document things like this. Whether that ends up being maintained as part of the guidelines or separately hasn't even been discussed yet, but at least you'll be able to send a PR in pagure to get something updated. - J< ___ python-devel mailing list -- python-devel@lists.fedoraproject.org To unsubscribe send an email to python-devel-le...@lists.fedoraproject.org

I think that macros we care about should be on that page, not just at that link. However, you should check with tibbs/FPC about whether the definitions/list of macros are an altogether dated concept. When I was there we used those because spec files are just shell scripts. For a sysadmin to become a packager, they just needed to understand a few concepts about the structure of the spec file but otherwise they just put their steps from the command line into the spec. Defining the macros on the page allowed those users to see how the macro replaced some steps of their manual procedure. However, that may no longer be the audience of the guidelines. It may be that they're now targeting programmers or packagers who don't have the same intimate relationship to the command line as sysadmin and have a greater comfort learning a domain specific language to do a job. In that case, perhaps the entire concept of enumerating the macros is unneeded for that target audience. Instead, simply introducing the macros when they're used in the guidelines is enough. Talk to tibbs/FPC about what their thoughts are. > * if so, should we add a new section of the guidelines? something like >"Packaging setup.py-less projects"? > Rather than emphasising the absence of setup.py, I'd emphasise the use of wheel files: * "Defining an RPM based on a wheel build process" * "Defining an RPM based on a setup.py file" I would not emphasize the use of wheel files as they are not source and from flit's documentation, it doesn't appear that wheels are even central to it (contrast how much wheel is mentioned in its documentation compared to pyproject.tom). Instead I would emphasize flit itself as the build tool which we're using to transform the source into the files on our systems. If there's ever an alternative to flit which builds with wheels as part of that process we'll need new guidelines based on that so using wheel as the prime keyword that people associate with this build process instead of flit is not future proof either. -Toshio ___ python-devel mailing list -- python-devel@lists.fedoraproject.org To unsubscribe send an email to python-devel-le...@lists.fedoraproject.org

The key differences between it and setuptools are: 1. It's designed specifically for pure Python projects 2. It assumes it can get the list of files to package from git Those two assumptions sweep away a *lot* of the complexity in setuptools, and hence make flit far more beginner friendly. > * if so, should we add a new section of the guidelines? something like >"Packaging setup.py-less projects"? > Rather than emphasising the absence of setup.py, I'd emphasise the use of wheel files: * "Defining an RPM based on a wheel build process" * "Defining an RPM based on a setup.py file" The latter would just be a renamed https://fedoraproject.org/wiki/Packaging:Python#Example_common_spec_file - that is the setup.py based build process, but it isn't currently obvious that `pyX_build` and `pyX_install` assume the use of a setup.py file.

If that's still the case, then the answer would be "Yes, but only if you make sure the sdist still contains a suitable setup.py shim".
