# Certbot dependency pinning
|
||||
|
||||
As described in the developer guide, we try to pin Certbot's dependencies to
|
||||
well tested versions in almost all cases. Pinning Python dependencies across
|
||||
different environments like this is actually quite tricky though and the files
|
||||
under this directory make a somewhat reasonable, best effort approach to solve
|
||||
this problem.
|
||||
|
||||
## Python packaging background
|
||||
|
||||
### Sdists and wheels
|
||||
|
||||
Python projects are most commonly distributed on [PyPI](https://pypi.org/) as
|
||||
either a [source
|
||||
distribution](https://packaging.python.org/glossary/#term-Source-Distribution-or-sdist)
|
||||
or a [wheel](https://packaging.python.org/glossary/#term-Wheel). Wheels don't
|
||||
present a problem for us pinning dependencies because they offer a well defined
|
||||
format where the dependencies of a package can be easily parsed.
|
||||
|
||||
Source distributions or "sdists" are a problem though because they can contain
|
||||
arbitrary Python code that must be run to determine the dependencies of the
|
||||
package. This code could theoretically do anything, but it most commonly
|
||||
inspects the environment it is running in and changes the project's
|
||||
dependencies based the environment. As of writing this, we even do this in some
|
||||
of Certbot's packages as you can see
|
||||
[here](https://github.com/certbot/certbot/blob/8b610239bfcf7aac06f6e36d09a5abba3ba87047/certbot-dns-cloudflare/setup.py#L15-L27).
|
||||
This is a problem because it means the environment an sdist was run in affects
|
||||
the dependencies it declares making it difficult for us to determine Certbot's
|
||||
dependencies for an arbitrary environment. Luckily, this is becoming less and
|
||||
less of an issue with the increasing use of wheels, however, as of writing
|
||||
this, some of Certbot's dependencies are still only available as sdists on some
|
||||
platforms.
|
||||
|
||||
### Environment markers and pyproject.toml
|
||||
|
||||
Two other things have helped reduce the problems caused by sdists and are
|
||||
relevant here. The first is the usage of [environment
|
||||
markers](https://www.python.org/dev/peps/pep-0496/) which allows a package to
|
||||
consistently declare its conditional dependencies with a static string
|
||||
specifying the conditions where a dependency is required instead of dynamically
|
||||
generating the list of required dependencies at runtime. This static string
|
||||
keeps the package's declaration of its dependencies consistent across
|
||||
environments.
|
||||
|
||||
The other relatively recent change in Python packaging is the adoption of
|
||||
[pyproject.toml files](https://www.python.org/dev/peps/pep-0518/) which allows
|
||||
sdists to define their packages using a static file instead of a setup.py
|
||||
file, which has historically been the norm.
|
||||
Using a static file instead of arbitrary Python code makes it
|
||||
much easier for package declarations to be reliably interpreted. The
|
||||
introduction of pyproject.toml also allows for the use of build systems other
|
||||
than setuptools which becomes relevant in the next section of this doc.
|
||||
|
||||
## Our pinning system
|
||||
|
||||
### Overview
|
||||
|
||||
The files inside `tools/pinning` are used to generate Certbot's pinning files.
|
||||
The files under `oldest` are used to generate the constraints file used for our
|
||||
"oldest" tests while `current` is used to generate the constraints used
|
||||
everywhere else. `common` includes shared files that are used for both sets of
|
||||
pinnings.
|
||||
|
||||
Under `current` and `oldest`, there are two files as of writing this. One is a
|
||||
pyproject.toml file for use with [Poetry](https://python-poetry.org/) while
|
||||
the other is a script that can be run to regenerate pinnings. The
|
||||
pyproject.toml file defines a Python package that depends on everything we want
|
||||
to pin. This file largely just depends on our own local packages, however,
|
||||
extra dependencies can be declared to further constrain package versions or to
|
||||
declare additional dependencies.
|
||||
|
||||
The reason we use Poetry is that it is somewhat unique among Python packaging
|
||||
tools in that when locking dependencies, it makes a best effort approach to do
|
||||
this for all environments rather than just the current environment. This
|
||||
includes recursively resolving dependencies declared through environment
|
||||
markers that are not relevant for the current platform. It also includes
|
||||
checking all wheels and sdists of a package for dependencies when picking a
|
||||
specific version of a package from PyPI. You can see this in action through
|
||||
the inclusion of dependencies like pywin32 which we only have a dependency on
|
||||
for Windows.
|
||||
|
||||
### Potential problems
|
||||
|
||||
As of writing this, I'm aware of two potential problems with this pinning
|
||||
system. The first is largely described earlier in the doc which is the problem
|
||||
of sdists that use code to dynamically declare its dependencies. It's simply
|
||||
not feasible to ensure this arbitrary Python code declares its dependencies in
|
||||
the same way across all environments. Luckily, this is a largely a theoretical
|
||||
problem and I'm aware of no issues with our current dependencies.
|
||||
|
||||
The second problem with this approach is that build dependencies are not
|
||||
tracked and pinned. Unfortunately, [this seems to be a largely unsolved problem
|
||||
in Python right
|
||||
now](https://discuss.python.org/t/pinning-build-dependencies/8363). Our tooling
|
||||
ensures that when installing build dependencies when using our pinning files
|
||||
that versions from the pinning files are used (see
|
||||
https://github.com/certbot/certbot/pull/8443 for more info about that), but I'm
|
||||
not aware of any tool that automates the process of tracking and pinning down
|
||||
build dependencies. For now, if we find any unpinned build dependencies, we can
|
||||
declare a dependency on them in pyproject.toml. If a build dependency isn't
|
||||
included in the constraints file, pip will use the latest version available on
|
||||
PyPI.
|
||||
|
||||
## Theoretical future work
|
||||
|
||||
I think the system described above should work pretty well and I think it's
|
||||
much better than the system we had before where how to update things like our
|
||||
"oldest" pinnings was an open question. If we wanted to improve on this in the
|
||||
future though, I think things to consider would be:
|
||||
|
||||
1. We could require that wheels are used for all of our dependencies. If a
|
||||
wheel is not available for one of our dependencies, we could try to work
|
||||
with upstream to change that or build it and host it locally for ourselves.
|
||||
(If we do the latter, how to pin build dependencies when building the wheel
|
||||
remains an open question.)
|
||||
2. We could only really try to pin our dependencies for certain environments.
|
||||
This would be done by doing something like installing our packages in each
|
||||
environment we care about and saving the output of a command like `pip
|
||||
freeze`. With our use of snaps and Docker, this may be somewhat reasonable
|
||||
because we could base them all on a common system like Ubuntu LTS, however,
|
||||
it's not entirely trivial because we still have problems such as supporting
|
||||
multiple CPU architectures and pinning dependencies for Windows. Alternative
|
||||
development and test environments also wouldn't be fully supported.
|
||||
3. We could help build better tooling that solves some of the problems with
|
||||
this approach or adopts it when it becomes available.
