First step, sufficient to run
```shell
cargo run --bin puffin-dev -- build --editable -w target/editables/ scripts/editable-installs/poetry_editable/
```
and check the wheel to confirm its working. Tests will be added with the
pip-sync integration.
## Summary
When installing a local wheel, we need to avoid removing the zipped
wheel (since it lives outside of the cache), _and_ need to ensure that
we unzip the wheel into the cache (rather than replacing the zipped
wheel, which may even live outside of the project).
Closes https://github.com/astral-sh/puffin/issues/553.
This PR modifies the source distribution building to replace any
existing targets after building the new wheel. In some cases, the
existence of an existing target may be indicative of a bug, so we warn.
It's partially a workaround for some (but not all) of the errors in
https://github.com/astral-sh/puffin/issues/554.
Ensure we're using atomic writes everywhere in our cache to avoid broken
cache records and error with parallel puffin actions
(https://github.com/astral-sh/puffin/pull/544#issuecomment-1838841581).
All json files that are written to the cache are written atomically and
the build wheels are written to temp dir and then moved atomically. I
didn't touch venv creation though, i don't think that's worth it since
python does not support atomic package installation through its design.
## Summary
This PR modifies `puffin-build` to be closer in behavior to
[pip](a15dd75d98/src/pip/_internal/pyproject.py (L53))
and
[build](de5b44b0c2/src/build/__init__.py (L94)).
Specifically, if a project contains a `[build-system]` field, but no
`build-backend`, we now perform a PEP 517 build (instead of using
`setup.py` directly) _and_ respect the `requires` of the
`[build-system]`. Without this change, we were failing to build source
distributions for packages like `ujson`.
Closes#527.

In a refactor, we lost the cache invalidation behavior for interpreter
markers, leading to stale interpreter errors for me when creating
environments with different Python versions. Specifically, the
modification timestamp used to be part of the _cache key_ when we used
`cacache`. Now it's not -- but it's stored within the cache. So we need
to validate the key after-the-fact.
After this change, two wheel caches remain: `built-wheels-v0` and
`wheels-v0`, docs screenshots below. Each contains both the wheel
metadata, cache policy and zip or unzipped wheels under the same name.
The zipped/unzipped strategy is as follows: In `pip-compile`, when we
build a wheel, we store it zipped. When `pip-sync` or a source dist
build in `pip-compile` need to install the wheel, we unzip it, remove
the file and replace it with the unzipped wheel.
This removes `WheelCache` and `UrlIndex` in favor of `Cache` plus
`WheelCache`. The non-built wheel cache now considers index urls and the
url for url wheels.
I'm unsure if we need the `Unzipper` type, this could just be a
function.
I move `no_index` into `IndexUrls` and started using `IndexUrl` up to
the clap level.
I left a number of TODOs in the code, namely performing the actual
invalidation of unzipped wheels and making the `InstallPlan` understand
cache invalidation (i.e. uninstall wheels when their remote changed).
Preparing for #235, some refactoring to `puffin_interpreter`.
* Added a dedicated error type instead of anyhow
* `InterpreterInfo` -> `Interpreter`
* `detect_virtual_env` now returns an option so it can be chained for
#235
Previously, we were assuming that `which <python>` return the path to
the python executable. This is not true when using pyenv shims, which
are bash scripts. Instead, we have to use `sys.executable`. Luckily,
we're already querying the python interpreter and can do it in that
pass.
We are also not allowed to cache the execution of the python interpreter
through the shim because pyenv might change the target. As a heuristic,
we check whether `sys.executable`, the real binary, is the same our
canonicalized `which` result.

One of the most common errors i observed are build failures due to
missing header files. On ubuntu, this generally means that you need to
install some `<...>-dev` package that the documentation tells you about,
e.g. [mysqlclient](https://github.com/PyMySQL/mysqlclient#linux) needs
`default-libmysqlclient-dev`, [some psycopg
versions](https://www.psycopg.org/psycopg3/docs/basic/install.html#local-installation)
(i remember that this was always required at some earlier point) require
`libpq-dev` and pygraphviz wants `graphviz-dev`. This is quite common
for many scientific packages (where conda has an advantage because they
can provide those package as a dependency).
The error message can be completely inscrutable if you're just a python
programmer (or user) and not a c programmer (example: pygraphviz):
```
warning: no files found matching '*.png' under directory 'doc'
warning: no files found matching '*.txt' under directory 'doc'
warning: no files found matching '*.css' under directory 'doc'
warning: no previously-included files matching '*~' found anywhere in distribution
warning: no previously-included files matching '*.pyc' found anywhere in distribution
warning: no previously-included files matching '.svn' found anywhere in distribution
no previously-included directories found matching 'doc/build'

3020 | #include "graphviz/cgraph.h"
| ^~~~~~~~~~~~~~~~~~~
compilation terminated.
error: command '/usr/bin/gcc' failed with exit code 1
```
The only relevant part is `Fatal error: graphviz/cgraph.h: No such file
or directory`. Why is this file not there and how do i get it to be
there?
This is even harder to spot in pip's output, where it's 11 lines above
the last line:
I've special cased missing headers and made sure that the last line
tells you the important information: We're missing some header, please
check the documentation of {package} {version} for what to install:
Scrolling up:
The difference gets even clearer with a default ubuntu terminal with its
80 columns:
---
Note that the situation is better for a missing compiler, there i get:
```
[...]
warning: no previously-included files matching '*~' found anywhere in distribution
warning: no previously-included files matching '*.pyc' found anywhere in distribution
warning: no previously-included files matching '.svn' found anywhere in distribution
no previously-included directories found matching 'doc/build'
error: command 'gcc' failed: No such file or directory
---
```
Putting the last line into google, the first two results tell me to
`sudo apt-get install gcc`, the third even tells me about `sudo apt
install build-essential`
## Summary
This PR adds support for Git dependencies, like:
```
flask @ git+https://github.com/pallets/flask.git
```
Right now, they're only supported in the resolver (and not the
installer), since the installer doesn't yet support source distributions
at all.
The general approach here is based on Cargo's Git implementation.
Specifically, I adapted Cargo's
[`git`](23eb492cf9/src/cargo/sources/git/mod.rs)
module to perform the cloning, which is based on `libgit2`.
As compared to Cargo's implementation, I made the following changes:
- Removed any unnecessary code.
- Fixed any Clippy errors for our stricter ruleset.
- Removed the dependency on `curl`, in favor of `reqwest` which we use
elsewhere.
- Removed the ability to use `gix`. Cargo allows the use of `gix` as an
experimental flag, but it only supports a small subset of the
operations. When Cargo fully adopts `gix`, we should plan to do the
same.
- Removed Cargo's host key checking. We need to re-add this! I'll do it
shortly.
- Removed Cargo's progress bars. We should re-add this too, but we use
`indicatif` and Cargo had their own thing.
There are a few follow-ups to consider:
- Adding support in the installer.
- When we lock, we should write out the Git URL that includes the exact
SHA. This lets us cache in perpetuity and avoids dependencies changing
without re-locking.
- When we resolve, we should _always_ try to refresh Git dependencies.
(Right now, we skip if the wheel was already built.)
I'll work on the latter two in follow-up PRs.
Closes#202.
There are packages such as DTLSSocket 0.1.16 that say
```toml
[build-system]
requires = ["Cython<3", "setuptools", "wheel"]
```
In this case we need to install requires PEP 517 style but then call setup.py in the
legacy way
Part of making home-assistant work
Previously, we had two python interpreter metadata structs, one in
gourgeist and one in puffin. Both would spawn a subprocess to query
overlapping metadata and both would appear in the cli crate, if you
weren't careful you could even have to different base interpreters at
once. This change unifies this to one set of metadata, queried and
cached once.
Another effect of this crate is proper separation of python interpreter
and venv. A base interpreter (such as `/usr/bin/python/`, but also pyenv
and conda installed python) has a set of metadata. A venv has a root and
inherits the base python metadata except for `sys.prefix`, which unlike
`sys.base_prefix`, gets set to the venv root. From the root and the
interpreter info we can compute the paths inside the venv. We can reuse
the interpreter info of the base interpreter when creating a venv
without having to query the newly created `python`.
This is isn't ready, but it can resolve
`meine_stadt_transparent==0.2.14`.
The source distributions are currently being built serially one after
the other, i don't know if that is incidentally due to the resolution
order, because sdist building is blocking or because of something in the
resolver that could be improved.
It's a bit annoying that the thing that was supposed to do http requests
now suddenly also has to a whole download/unpack/resolve/install/build
routine, it messes up the type hierarchy. The much bigger problem though
is avoid recursive crate dependencies, it's the reason for the callback
and for splitting the builder into two crates (badly named atm)
As elsewhere, we just use the `pip` and `pip-compile` APIs. So we
support `--index-url` to override PyPI, then `--extra-index-url` to add
_additional_ indexes, and `--no-index` to avoid hitting the index at
all.
Closes#156.
The need for this became clear when working on the source distribution
integration into the resolver.
While at it i also switch the `WheelFilename` version to the parsed
`pep440_rs` version now that we have this crate.
Gets rid of the custom `DistInfo` struct in the site-packages
abstraction in favor of a new kind of distribution
(`InstalledDistribution`). No change in behavior.
This is also a lot faster. Unfortunately it copies a lot of code from
the sync cli since the `Printer` is private.
The first commit are some refactorings i made when i thought about how i
could reuse the existing code.
Support calling `prepare_metadata_for_build_wheel`, which can give you
the metadata without executing the actual build if the backend supports
it.
This makes the code a lot uglier since we effectively have a state
machine:
* Setup: Either venv plus requires (PEP 517) or just a venv (setup.py)
* Get metadata (optional step): None (setup.py) or
`prepare_metadata_for_build_wheel` and saving that result
* Build: `setup.py`, `build_wheel()` or
`build_wheel(metadata_directory=metadata_directory)`, but i think i got
general flow right.
@charliermarsh This is a "barely works but unblocks building on top"
implementation, say if you want more polishing (i'll look at this again
tomorrow)
This adds a basic sdist builder that has been tested with two source
distributions, one with a PEP 517 backend and one with setup.py.
It uses pip for requirements installation atm, lacks testing in all
directions, lacks checks for recursive requirements, can't pass in
already resolved versions, doesn't support prepare metadata for build to
allow resolution to continue without doing the actual (native) build,
error messages are mediocre, etc.
