Previously, we just pulled the latest commit from `main` on every
update. This causes problems when you do not intend to update the
scenarios as in #787.
This bumps to the latest `packse` commit without new scenarios.
Adds support for a `PUFFIN_NO_WRAP` environment variable which disables
line wrapping in `miette` output.
We set this variable in the scenario tests to improve the readability of
snapshots.
I contributed the ability to disable line wrapping upstream at
https://github.com/zkat/miette/pull/328
This fixes a compilation error with tests on current `main`. I didn't
track down the exact provenance, but I'd guess it's the result of a
botched merge. (i.e., Two or more PRs that pass CI independently, but
when merged cause failures.)
I'm still confused about it, but this seems to do the right thing?
`HierarchicalLayer` internally has [`let ansi =
io::stderr().is_terminal();`](https://github.com/davidbarsky/tracing-tree/blob/fcd9eed2528e41cd776b19b9ba45d338ae62a5fc/src/lib.rs#L74),
so the logging itself is already correctly uncolored, but errors in the
log weren't.
Test command, ran with network deactivated:
```shell
RUST_LOG=debug cargo run --bin puffin -- pip-compile -v ./scripts/popular_packages/pypi_8k_downloads.txt 2> log.txt

Following #757, improves the script for generating scenario test cases
with:
- A requirements file
- Support for downloading packse scenarios from GitHub dynamically
- Running rustfmt on the generated test file
- Updating snapshots / running tests
As mentioned in #746, instead of just installing the scenario root we
will unpack the root dependencies into the install command to allow
better coverage of direct user requests with scenarios.
I added display of the package tree provided by each scenario.
Use a mustache template for iterative replacements.
Adds tests using packse test scenarios! Uses `test.pypi.org` as a
backing index.
Tests are generated by a simple Python script. Requires
https://github.com/zanieb/packse/pull/49.
This opens us to a slight attack surface, as we cannot force use of
`test.pypi.org` only and someone could register these package names on
the real `pypi.org` index with malicious content. I could publish these
packages there too.
## Summary
This PR modifies the resolver to treat the Python version as a package,
which allows for better error messages (since we no longer treat
incompatible packages as if they "don't exist at all").
There are a few tricky pieces here...
First, we need to track both the interpreter's Python version and the
_target_ Python version, because we support resolving for other versions
via `--python 3.7`.
Second, we allow using incompatible wheels during resolution, as long as
there's a compatible source distribution. So we still need to test for
`requires-python` compatibility when selecting distributions.
This could use more testing, but it feels like an area where `packse`
would be more productive than writing PyPI tests.
Closes https://github.com/astral-sh/puffin/issues/406.
## Summary
This PR makes the `pypi_types::File` a response-only type (i.e., a type
that's only used when deserializing over the wire), and adds a separate
internal `File` type. Right now, the representations are similar, but
already, we can avoid the "lenient" deserialization on our internal
`File` type, and avoid the special-casing of the property names that's
required in the JSON. Over time, we can evolve this representation
entirely separately from the representation we receive from PyPI and
other indexes.
This allows the default index URL to be easily overridden with a local
index e.g. a `packse` server
```
export PUFFIN_INDEX_URL="http://localhost:3141/packages/all/+simple"
```
The high level goal here is to improve the tests for the version parser.
Namely, we now check not just that version strings parse successfully,
but that they parse to the expected result.
We also do a few other cleanups. Most notably, `Version` is now an
opaque type so that we can more easily change its representation going
forward.
Reviewing commit-by-commit is suggested. :-)
The test creates a cache from multiple sources and injects faults (once
using invalid data and once by making the files unreadable on the fs
level), then resolves again.
I didn't test git because it has its own locking and correctness logic.
The main drawback is that this test is slow (2.5s for me), we could
`#[ignore]` it.
This is a pure refactor to follow-up #690, to separate the metadata that
we know upfront about distributions (like the version, for
registry-based distributions) vs. the metadata that requires building
(like the version, for URL-based distributions).
We now show the fully-resolved URL, rather than the URL as given by the
user, _everywhere_ except for the output resolution file (which should
retain relative paths, unexpanded environment variables, etc.).
Closes https://github.com/astral-sh/puffin/issues/687.
With `Option<T>` and `.unwrap_or_default()` later, the default of `T`
isn't shown in the help output.

This PR uses borrowed data in `BuildDispatch` which makes creating a
`BuildDispatch` extremely cheap (only one allocation, for the Python
executable). I can be talked out of this, it will have no measurable
impact.
Separate branch for rebasing #677 onto main because i don't trust the
rebase enough to force push.
Closes#677.

If you install `black` from PyPI, then `-e ../black`, we need to
uninstall the existing `black`. This sounds simple, but that in turn
requires that we _know_ `-e ../black` maps to the package `black`, so
that we can mark it for uninstallation in the install plan. This, in
turn, means that we need to build editable dependencies prior to the
install plan.
This is just a bunch of reorganization to fix that specific bug
(installing multiple versions of `black` if you run through the above
workflow): we now run through the list of editables upfront, mark those
that are already installed, build those that aren't, and then ensure
that `InstallPlan` correctly removes those that need to be removed, etc.
Closes#676.

Per the title: adds support for `-e` installs to `puffin pip-install`.
There were some challenges here around threading the editable installs
to the right places. Namely, we want to build _once_, then reuse the
editable installs from the resolution. At present, we were losing the
`editable: true` flag on the `Dist` that came back through the
resolution, so it required some changes to the resolver.
Closes https://github.com/astral-sh/puffin/issues/672.
This PR modifies `SitePackages` to store all distributions in a flat
vector, and maintain two indexes (hash maps) from "per-element data for
an element in the vector" to "index of that element". This enables us to
maintain a map on both package name and editable URL.
Two low-hanging fruits as optimizations for version parsing: A fast path
for release only versions and removing the regex from version specifiers
(still calling into version's parsing regex if required). This enables
optimizing the serde format since we now see the serde part instead of
only PEP 440 parsing. I intentionally didn't rewrite the full PEP 440 at
this step.

## Summary
This PR ensures that we re-use the resolution to install the build
dependencies when building a source distribution. Currently, we only
pass along the list of requirements, and then use the `Finder` to map
each requirement to a distribution. But we already determine the correct
distribution when resolving!
Closes https://github.com/astral-sh/puffin/issues/655.
## Summary
This PR enables users to express relative dependencies via environment
variables. Like pip, PDM, Hatch, Rye, and others, we now allow users to
express dependencies like:
```text
flask @ file://${PROJECT_ROOT}/flask-3.0.0-py3-none-any.whl
```
In the compiled requirements file, we'll also preserve the unexpanded
environment variable.
Closes https://github.com/astral-sh/puffin/issues/592.
## Summary
This PR adds a `VerbatimUrl` struct to preserve verbatim URLs throughout
the resolution and installation pipeline. In short, alongside the parsed
`Url`, we also keep the URL as written by the user. This enables us to
display the URL exactly as written by the user, rather than the
serialized path that we use internally.
This will be especially useful once we start expanding environment
variables since, at that point, we'll be able to write the version of
the URL that includes the _unexpected_ environment variable to the
output file.
