## Summary
This ensures that (like Cargo) we don't suffer from
https://github.com/advisories/GHSA-r5w3-xm58-jv6j, by way of checking
known hosts when fetching via `libgit2`.
The implementation is taken from Cargo itself, modified to remove all
configuration, since we don't yet support configuration for known hosts,
etc.
Closes#285.
Our existing detection doesn't work on Windows, because we canoncalize
the interpreter path but not `info.sys_executable`, so the former
includes the UNC prefix, etc. This is cross-platform and gets at the
intent of the check.
## Summary
This PR adds a `NormalizedDisplay` trait that we can use for user-facing
paths, to strip the UNC prefix on Windows.
On other platforms, the implementation is a no-op (vs. `Display`).
I audited all usages of `.display()`, and changed any that were
user-facing, either via `println!` or `eprintln!`, or by way of being
included in error messages. I did _not_ change uses that were only in
tests or only went to tracing.
Closes https://github.com/astral-sh/puffin/issues/1084.
## Summary
When we unzip wheels in the cache, we write the directories out to an
`archive-v0` bucket, and then symlink into that bucket from the
`wheels-v0` and `built-wheels-v0` buckets.
On Windows, symlinks are not well supported. Specifically, they need to
be explicitly enabled by the user. So, instead of symlinks, we now use
junctions, which are well-supported on Windows, and allow you to
(effectively) symlink a directory to another directory. This PR
implements said junction support, which gets the core installer working
on Windows.
In the past, we also used symlinks to implement another primitive: we
wanted to be able to replace a directory "atomically" (I put
"atomically" in quotes because I don't know if it's actually a
guaranteed atomic operation), in case someone was trying to use the
directory while we were replacing it (as opposed to deleting the
directory, then moving it into place).
On Windows, it doesn't appear to be possible to atomically replace a
junction. So instead, I'm using a new design, whereby the cache always
returns canonicalized paths. We know these canonicalized paths are
unique and won't be replaced, so they're safe for writers to rely on. In
general, when we write new data to the cache, we now return the
canonicalized path. When we read from the cache, and try to identify
(e.g.) the set of wheels available to us, we canonicalize the links
immediately and consider them non-existent if that operation fails.
Closes#1085.

Requires https://github.com/zanieb/pubgrub/pull/20
In short, `UnusableDependencies` can be generalized into `Unavailable`
which encompasses incompatibilities where a package range which is
unusable for some inherent reason as well as when its dependencies are
unusable. We can eventually use this to track more incompatibilities in
the solver. I made the reason string required because I can't see a case
where we should leave it out.
Additionally, this improves the display of conflicts in the root
requirements.
## Summary
First batch of changes for windows support. Notable changes:
* Fixes all compile errors and added windows specific paths.
* Working venv creation on windows, both from a base interpreter and
from a venv. This requires querying `stdlib` from the sysconfig paths to
find the launcher.
* Basic url/path conversion handling for windows.
* `if cfg!(...)` instead of `#[cfg()]`. This should make it easier to
keep everything compiling across platforms.
## Outlook
Test summary: 402 tests run: 299 passed (15 slow), 103 failed, 1 skipped
There are various reason for the remaining test failure:
* Windows-specific colorama and tzdata dependencies that change the
snapshot slightly. This is by far the biggest batch.
* Some url-path handling issues. I fixed some in the PR, some remain.
* Lack of the latest python patch versions for older pythons on my
machine, since there are no builds for windows and we need to register
them in the registry for them to be picked up for `py --list-paths` (CC
@zanieb RE #1070).
* Lack of entrypoint launchers.
* ... likely more
This PR replaces a few uses of hash maps/sets with btree maps/sets and
index maps/sets. This has the benefit of guaranteeing a deterministic
order of iteration.
I made these changes as part of looking into a flaky test.
Unfortunately, I'm not optimistic that anything here will actually fix
the flaky test, since I don't believe anything was actually dependent
on the order of iteration.
## Summary
One problem we have in the cache today is that we can't overwrite
entries atomically, because we store unzipped _directories_ in the cache
(which makes installation _much_ faster than storing zipped
directories). So, if you ignore the existing contents of the cache when
writing, you might run into an error, because you might attempt to write
a directory where a directory already exists.
This is especially annoying for cache refresh, because in order to
refresh the cache, we have to purge it (i.e., delete a bunch of stuff),
which is also highly unsafe if Puffin is running across multiple threads
or multiple processes.
The solution I'm proposing here is that whenever we persist a
_directory_ to the cache, we persist it to a special "archive" bucket.
Then, within the other buckets, directory entries are actually symlinks
into that "archive" bucket. With symlinks, we can atomically replace,
which means we can easily overwrite cache entries without having to
delete from the cache.
The main downside is that we'll now accumulate dangling entries in the
"archive" bucket, and so we'll need to implement some form of garbage
collection to ensure that we remove entries with no symlinks. Another
downside is that cache reads and writes will be a bit slower, since we
need to deal with creating and resolving these symlinks.
As an example... after this change, the cache entry for this unzipped
wheel is actually a symlink:

Then, within the archive directory, we actually have two unique entries
(since I intentionally ran the command twice to ensure overwrites were
safe):

## Summary
This is a refactor of the source distribution cache that again aims to
make the cache purely additive. Instead of deleting all built wheels
when the cache gets invalidated (e.g., because the source distribution
changed on PyPI or something), we now treat each invalidation as its own
cache directory. The manifest inside of the source distribution
directory now becomes a pointer to the "latest" version of the source
distribution cache.
Here's a visual example:

With this change, we avoid deleting built distributions that might be
relied on elsewhere and maintain our invariant that the cache is purely
additive. The cost is that we now preserve stale wheels, but we should
add a garbage collection mechanism to deal with that.
Mirroring `virtualenv -p` and driven by the lack of `pythonx.y` in
`PATH` on windows, this PR adds `-p x.y` support to `puffin venv` (first
commit).
Supported formats:
* NEW: `-p 3.10` searches for an installed Python 3.10 (Looking for
`python3.10` on linux/mac).
Specifying a patch version is not supported
* `-p python3.10` or `-p python.exe` looks for a binary in `PATH`
* `-p /home/ferris/.local/bin/python3.10` uses this exact Python
In the second commit, we add python interpreter search on windows using
`py --list-paths`. On windows, all python are called `python.exe` so the
unix trick of looking for `python{}.{}` in `PATH` doesn't work. Instead,
we ask the python launcher for windows to tell us about all installed
packages. We should eventually migrate this to [PEP
514](https://peps.python.org/pep-0514/) by reading the registry entries
ourselves.
## Summary
This PR adds support for PyPy wheels by changing the compatible tags
based on the implementation name and version of the current interpreter.
For now, we only support CPython and PyPy, and explicitly error out when
given other interpreters. (Is this right? Should we just fallback to
CPython tags...? Or skip the ABI-specific tags for unknown
interpreters?)
The logic is based on
4d85340613/src/packaging/tags.py (L247).
Note, however, that `packaging` uses the `EXT_SUFFIX` variable from
`sysconfig`... Instead, I looked at the way that PyPy formats the tags,
and recreated them based on the Python and implementation version. For
example, PyPy wheels look like
`cchardet-2.1.7-pp37-pypy37_pp73-win_amd64.whl` -- so that's `pp37` for
PyPy with Python version 3.7, and then `pypy37_pp73` for PyPy with
Python version 3.7 and PyPy version 7.3.
Closes https://github.com/astral-sh/puffin/issues/1013.
## Test Plan
I tested this manually, but I couldn't find macOS universal PyPy
wheels... So instead I added `cchardet` to a `requirements.in`, ran
`cargo run pip sync requirements.in --index-url
https://pypy.kmtea.eu/simple --verbose`, and added logging to verify
that the platform tags matched (even if the architecture didn't).
Adds support for disabling installation from pre-built wheels i.e. the
package must be built from source locally.
We will still always use pre-built wheels for metadata during
resolution.
Available via `--no-binary` and `--no-binary-package <name>` flags in
`pip install` and `pip sync`. There is no flag for `pip compile` since
no installation happens there.
```
--no-binary
Don't install pre-built wheels.
When enabled, all installed packages will be installed from a source distribution.
The resolver will still use pre-built wheels for metadata.
--no-binary-package <NO_BINARY_PACKAGE>
Don't install pre-built wheels for a specific package.
When enabled, the specified packages will be installed from a source distribution.
The resolver will still use pre-built wheels for metadata.
```
When packages are already installed, the `--no-binary` flag will have no
affect without the `--reinstall` flag. In the future, I'd like to change
this by tracking if a local distribution is from a pre-built wheel or a
locally-built wheel. However, this is significantly more complex and
different than `pip`'s behavior so deferring for now.
For reference, `pip`'s flag works as follows:
```
--no-binary <format_control>
Do not use binary packages. Can be supplied multiple times, and each time adds to the
existing value. Accepts either ":all:" to disable all binary packages, ":none:" to empty the
set (notice the colons), or one or more package names with commas between them (no colons).
Note that some packages are tricky to compile and may fail to install when this option is
used on them.
```
Note we are not matching the exact `pip` interface here because it seems
complicated to use. I think we may want to consider adjusting our
interface for this behavior since we're not entirely compatible anyway
e.g. I think `--force-build` and `--force-build-package` are clearer
names. We could also consider matching the `pip` interface or only
allowing `--no-binary <package>` for compatibility. We can of course do
whatever we want in our _own_ install interfaces later.
Additionally, we may want to further consider the semantics of
`--no-binary`. For example, if I run `pip install pydantic --no-binary`
I expect _just_ Pydantic to be installed without binaries but by default
we will build all of Pydantic's dependencies too.
This work was prompted by #895, as it is much easier to measure
performance gains from building source distributions if we have a flag
to ensure we actually build source distributions. Additionally, this is
a flag I have used frequently in production to debug packages that ship
Cythonized wheels.
## Summary
I don't know if this is actually a good change, but it tries to make the
editable install experience more consistent. Specifically, we now
support...
```
# Use a relative path with a `file://` prefix.
# Prior to this PR, we supported `file:../foo`, but not `file://../foo`, which felt inconsistent.
-e file://../foo
# Use environment variables with paths, not just URLs.
# Prior to this PR, we supported `file://${PROJECT_ROOT}/../foo`, but not the below.
-e ${PROJECT_ROOT}/../foo
```
Importantly, `-e file://../foo` is actually not supported by pip... `-e
file:../foo` _is_ supported though. We support both, as of this PR. Open
to feedback.
## Summary
- This was inherited from
d719988323/src/metadata.rs (LL78C2-L91C26)
- ...which introduced this code here:
9cd1d43f7c
- ...with the originating issue here:
https://github.com/PyO3/maturin/issues/612
- ...and the upstream issue here:
https://github.com/staktrace/mailparse/issues/50
It seems like the goal was to support Unicode in certain header fields,
but I don't think this is necessary for us. We only use
`get_first_value` for `Requires-Python`, which has to be ASCII, doesn't
it?
In my testing, it seems like the `charset` hack can also be removed. The
tests I copied over actually work without it, which makes me a bit
skeptical.
The main benefit here is that we get to a remove a _big_ dependency
stack, including Chumsky and Stacker and psm which have limited
cross-platform support.
## Summary
I'm running into some annoyances converting `&Version` to
`&PubGrubVersion` (which is just a wrapper type around `Version`), and I
realized... We don't even need `PubGrubVersion`?
The reason we "need" it today is due to the orphan trait rule: `Version`
is defined in `pep440_rs`, but we want to `impl
pubgrub::version::Version for Version` in the resolver crate.
Instead of introducing a new type here, which leads to a lot of
awkwardness around conversion and API isolation, what if we instead just
implement `pubgrub::version::Version` in `pep440_rs` via a feature? That
way, we can just use `Version` everywhere without any confusion and
conversion for the wrapper type.
Add directory `--find-links` support for local paths to pip-compile.
It seems that pip joins all sources and then picks the best package. We
explicitly give find links packages precedence if the same exists on an
index and locally by prefilling the `VersionMap`, otherwise they are
added as another index and the existing rules of precedence apply.
Internally, the feature is called _flat index_, which is more meaningful
than _find links_: We're not looking for links, we're picking up local
directories, and (TBD) support another index format that's just a flat
list of files instead of a nested index.
`RegistryBuiltDist` and `RegistrySourceDist` now use `WheelFilename` and
`SourceDistFilename` respectively. The `File` inside `RegistryBuiltDist`
and `RegistrySourceDist` gained the ability to represent both a url and
a path so that `--find-links` with a url and with a path works the same,
both being locked as `<package_name>@<version>` instead of
`<package_name> @ <url>`. (This is more of a detail, this PR in general
still work if we strip that and have directory find links represented as
`<package_name> @ file:///path/to/file.ext`)
`PrioritizedDistribution` and `FlatIndex` have been moved to locations
where we can use them in the upstack PR.
I added a `scripts/wheels` directory with stripped down wheels to use
for testing.
We're lacking tests for correct tag priority precedence with flat
indexes, i only confirmed this manually since it is not covered in the
pip-compile or pip-sync output.
Closes#876
There is no guarantee that indexes provide hashes at all or the sha256
we support specifically. [PEP
503](https://peps.python.org/pep-0503/#specification):
> The URL SHOULD include a hash in the form of a URL fragment with the
following syntax: #<hashname>=<hashvalue>, where <hashname> is the
lowercase name of the hash function (such as sha256) and <hashvalue> is
the hex encoded digest.
We instead use the url as input to generate a hash when caching.
In the past, I moved us to `owo-colors`
(https://github.com/astral-sh/puffin/pull/121); then, we moved back,
because we ran into issues with overriding the settings to force-disable
colors. But `anstream` solved those problems, so I'm moving us _back_ to
`owo-colors`, since it's what `anstream` recommends, and it's already
used by many of our dependencies (`miette`, `configparser`).

## Summary
We can use `anstream` for all color control, rather than going through
`colored`. Note that we still need the `colored` crate, since `colored`
and `anstream` solve different problems. (`anstream` recommends using
`owo-colors` alongside it, but `colored` seems to work fine?)
Resolves the issue raised in
https://github.com/astral-sh/puffin/pull/742 via `anstream` rather than
`colored`.
Closes https://github.com/astral-sh/puffin/issues/782.
The semantics are a bit unintuitive because `--python-version` is a
preference when looking for a python version without a venv, but if we
don't find that exact version we'll take `python3` and patch the
markers. This will make more sense once we start provisioning python
builds.
We can now resolve black with both python 3.8 and 3.12, with or without
that python version being in scope. In the example below,
`PATH=$HOME/.cargo/bin:/usr/bin` removes the pyenv builds and leaves
only `python3`, which is python 3.11.

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
## 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 crate started off as generic caching utilities, but we started
adding a lot of Puffin-specific stuff (like the cache buckets
abstraction that knows about Git vs. direct URL vs. indexes and so on).
This PR moves the generic stuff into a new `cache-key` crate.
I don't have a good testing strategy here (I'm manually testing against
`devpi` via `packse`), but the HTML index uses (e.g.)
`data-requires-python=">=3.8"`, so we need to decode.
