For users who were using absolute paths in the `pyproject.toml`
previously, this is a behavior change: We now convert all absolute paths
in `path` entries to relative paths. Since i assume that no-one relies
on absolute path in their lockfiles - they are intended to be portable -
I'm tagging this as a bugfix.

## Summary
This PR rewrites the `MarkerTree` type to use algebraic decision
diagrams (ADD). This has many benefits:
- The diagram is canonical for a given marker function. It is impossible
to create two functionally equivalent marker trees that don't refer to
the same underlying ADD. This also means that any trivially true or
unsatisfiable markers are represented by the same constants.
- The diagram can handle complex operations (conjunction/disjunction) in
polynomial time, as well as constant-time negation.
- The diagram can be converted to a simplified DNF form for user-facing
output.
The new representation gives us a lot more confidence in our marker
operations and simplification, which is proving to be very important
(see https://github.com/astral-sh/uv/pull/5733 and
https://github.com/astral-sh/uv/pull/5163).
Unfortunately, it is not easy to split this PR into multiple commits
because it is a large rewrite of the `marker` module. I'd suggest
reading through the `marker/algebra.rs`, `marker/simplify.rs`, and
`marker/tree.rs` files for the new implementation, as well as the
updated snapshots to verify how the new simplification rules work in
practice. However, a few other things were changed:
- [We now use release-only comparisons for `python_full_version`, where
we previously only did for
`python_version`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/algebra.rs#L522).
I'm unsure how marker operations should work in the presence of
pre-release versions if we decide that this is incorrect.
- [Meaningless marker expressions are now
ignored](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/parse.rs#L502).
This means that a marker such as `'x' == 'x'` will always evaluate to
`true` (as if the expression did not exist), whereas we previously
treated this as always `false`. It's negation however, remains `false`.
- [Unsatisfiable markers are written as `python_version <
'0'`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/tree.rs#L1329).
- The `PubGrubSpecifier` type has been moved to the new `uv-pubgrub`
crate, shared by `pep508-rs` and `uv-resolver`. `pep508-rs` also depends
on the `pubgrub` crate for the `Range` type, we probably want to move
`pubgrub::Range` into a separate crate to break this, but I don't think
that should block this PR (cc @konstin).
There is still some remaining work here that I decided to leave for now
for the sake of unblocking some of the related work on the resolver.
- We still use `Option<MarkerTree>` throughout uv, which is unnecessary
now that `MarkerTree::TRUE` is canonical.
- The `MarkerTree` type is now interned globally and can potentially
implement `Copy`. However, it's unclear if we want to add more
information to marker trees that would make it `!Copy`. For example, we
may wish to attach extra and requires-python environment information to
avoid simplifying after construction.
- We don't currently combine `python_full_version` and `python_version`
markers.
- I also have not spent too much time investigating performance and
there is probably some low-hanging fruit. Many of the test cases I did
run actually saw large performance improvements due to the markers being
simplified internally, reducing the stress on the old `normalize`
routine, especially for the extremely large markers seen in
`transformers` and other projects.

## Summary
This PR adds a `DistExtension` field to some of our distribution types,
which requires that we validate that the file type is known and
supported when parsing (rather than when attempting to unzip). It
removes a bunch of extension parsing from the code too, in favor of
doing it once upfront.
Closes https://github.com/astral-sh/uv/issues/5858.
Currently, the entry for a package+version+source table is called
`distribution`. That is incorrect, the `sdist` and `wheel` fields inside
of that table are distributions, the table itself is for a package. We
also align ourselves closer with PEP 751.
I went through `lock.rs` and renamed all occurrences of "distribution"
that actually referred to a "package".
This change invalidates all existing lockfiles.
Bikeshedding: Do we call it `package` or `packages`? See also
https://github.com/python/peps/pull/3877
`package` is nice because it looks like a header:
```toml
[[package]]
name = "anyio"
version = "4.3.0"
source = { registry = "https://pypi.org/simple" }
dependencies = [
{ name = "idna" },
{ name = "sniffio" },
]
sdist = { url = "3970183622/anyio-4.3.0.tar.gz", hash = "sha256:f75253795a87df48568485fd18cdd2a3fa5c4f7c5be8e5e36637733fce06fed6", size = 159642 }
wheels = [
{ url = "2f20c40b45/anyio-4.3.0-py3-none-any.whl", hash = "sha256:048e05d0f6caeed70d731f3db756d35dcc1f35747c8c403364a8332c630441b8", size = 85584 },
]
```
`packages` is nice because the field is not a single entry, but a list.

## Summary
Very subtle bug. The scenario is as follows:
- We resolve: `elmer-circuitbuilder = { git =
"https://github.com/ElmerCSC/elmer_circuitbuilder.git" }`
- The user then changes the request to: `elmer-circuitbuilder = { git =
"https://github.com/ElmerCSC/elmer_circuitbuilder.git", rev =
"44d2f4b19d6837ea990c16f494bdf7543d57483d" }`
- When we go to re-lock, we note two facts:
1. The "default branch" resolves to
`44d2f4b19d6837ea990c16f494bdf7543d57483d`.
2. The metadata for `44d2f4b19d6837ea990c16f494bdf7543d57483d` is
(whatever we grab from the lockfile).
- In the resolver, we then ask for the metadata for
`44d2f4b19d6837ea990c16f494bdf7543d57483d`. It's already in the cache,
so we return it; thus, we never add the
`44d2f4b19d6837ea990c16f494bdf7543d57483d` ->
`44d2f4b19d6837ea990c16f494bdf7543d57483d` mapping to the Git resolver,
because we never have to resolve it.
This would apply for any case in which a requested tag or branch was
replaced by its precise SHA. Replacing with a different commit is fine.
It only applied to `tool.uv.sources`, and not PEP 508 URLs, because the
underlying issue is that we aren't consistent about "automatically"
extracting the precise commit from a Git reference.
Closes https://github.com/astral-sh/uv/issues/5860.
## Summary
This is an alternative to `--require-hashes` which will validate a hash
if it's present, but ignore requirements that omit hashes or are absent
from the lockfile entirely.
So, e.g., transitive dependencies that are missing will _not_ error; nor
will dependencies that are included but lack a hash.
Closes https://github.com/astral-sh/uv/issues/3305.
* Use a dedicated `ResolverMarkers` check in the fork state. This is
better than the `MarkerTree::And(Vec::new())` check.
* Report the timing correct naming universal resolution instead of two
spaces around an empty string when there are no markers.
* On resolution error, show the split that we're in. I'm not sure how to
word this, since we're doing a universal resolution until we fork, so
the trace may contain information from requirements that are not part of
this fork.
Add support for path dependencies from a package in one workspace to a
package in another workspace, which it self has workspace dependencies.
Say we have a main workspace with packages `a` and `b`, and a second
workspace with `c` and `d`. We have `a -> b`, `b -> c`, `c -> d`. This
would previously lead to a mangled path for `d`, which is now fixed.
Like distribution paths, we split workspace paths into an absolute
install path and a relative (or absolute, if the user provided an
absolute path) lock path.

## Summary
Avoid serializing and writing the lockfile if a cheap comparison shows
that the contents have not changed.
## Test Plan
Shaves ~10ms off of https://github.com/astral-sh/uv/issues/4860 for me.
```
➜ transformers hyperfine "../../uv/target/profiling/uv lock" "../../uv/target/profiling/baseline lock" --warmup 3
Benchmark 1: ../../uv/target/profiling/uv lock
Time (mean ± σ): 130.5 ms ± 2.5 ms [User: 130.3 ms, System: 85.0 ms]
Range (min … max): 126.8 ms … 136.9 ms 23 runs
Benchmark 2: ../../uv/target/profiling/baseline lock

Summary
../../uv/target/profiling/uv lock ran
1.08 ± 0.04 times faster than ../../uv/target/profiling/baseline lock
```
This is an attempt to solve https://github.com/astral-sh/uv/issues/ by
applying the extra marker of the requirement to overrides and
constraints.
Say in `a` we have a requirements
```
b==1; python_version < "3.10"
c==1; extra == "feature"
```
and overrides
```
b==2; python_version < "3.10"
b==3; python_version >= "3.10"
c==2; python_version < "3.10"
c==3; python_version >= "3.10"
```
Our current strategy is to discard the markers in the original
requirements. This means that on 3.12 for `a` we install `b==3`, but it
also means that we add `c` to `a` without `a[feature]`, causing #4826.
With this PR, the new requirement become,
```
b==2; python_version < "3.10"
b==3; python_version >= "3.10"
c==2; python_version < "3.10" and extra == "feature"
c==3; python_version >= "3.10" and extra == "feature"
```
allowing to override markers while preserving optional dependencies as
such.
Fixes#4826
## Summary
This is what I consider to be the "real" fix for #8072. We now treat
directory and path URLs as separate `ParsedUrl` types and
`RequirementSource` types. This removes a lot of `.is_dir()` forking
within the `ParsedUrl::Path` arms and makes some states impossible
(e.g., you can't have a `.whl` path that is editable). It _also_ fixes
the `direct_url.json` for direct URLs that refer to files. Previously,
we wrote out to these as if they were installed as directories, which is
just wrong.
By splitting `path` into a lockable, relative (or absolute) and an
absolute installable path and by splitting between urls and paths by
dist type, we can store relative paths in the lockfile.
When creating a lockfile, lock the combined dependencies for all
packages in a workspace. This make the lockfile independent of where you
are in the workspace.
Fixes#3983
## Summary
This PR separates "gathering the requirements" from the rest of the
metadata (e.g., version), which isn't required when installing a
package's _dependencies_ (as opposed to installing the package itself).
It thus ensures that we don't need to build a package when a static
`pyproject.toml` is provided in `pip compile`.
Closes https://github.com/astral-sh/uv/issues/4040.
## Summary
Given `install -e dagster`, we need to assume that the user meant
`install -e ./dagster`, even though `install dagster` should _not_ be
treated as `install ./dagster`. I suspect pip will change this in the
future (since `pip install dagster` does _not_ meant `pip install
./dagster`) but for now it's what users expect.
Closes https://github.com/astral-sh/uv/issues/3994.
## Summary
This PR ensures that if a lockfile already contains a resolved reference
(e.g., you locked with `main` previously, and it locked to a specific
commit), and you run `uv lock`, we use the same SHA, even if it's not
the latest SHA for that tag. This avoids upgrading Git dependencies
without `--upgrade`.
Closes#3920.
## Summary
This will help prevent bugs like #3934 by unifying the implementations
for editables and non-editable unnamed requirements. Specifically, both
of these now go through the same parsing paths and use the same struct
representations (with the exception that the editable flag is flipped in
the first case):
```
-e ./foo/bar
./foo/bar
```
We also now support PEP 508 in editable URLs. It turns out this is just
a limitation in pip, so it's correct to support it. For example, this
now works:
```
-e black[d] @ file://${PROJECT_ROOT}/scripts/packages/black_editable
```
Closes#3941.
Closes#3942.
With the change, we remove the special casing of workspace dependencies
and resolve `tool.uv` for all git and directory distributions. This
gives us support for non-editable workspace dependencies and path
dependencies in other workspaces. It removes a lot of special casing
around workspaces. These changes are the groundwork for supporting
`tool.uv` with dynamic metadata.
The basis for this change is moving `Requirement` from
`distribution-types` to `pypi-types` and the lowering logic from
`uv-requirements` to `uv-distribution`. This changes should be split out
in separate PRs.
I've included an example workspace `albatross-root-workspace2` where
`bird-feeder` depends on `a` from another workspace `ab`. There's a
bunch of failing tests and regressed error messages that still need
fixing. It does fix the audited package count for the workspace tests.
## Summary
In general, it's not quite right to filter preferences by `--reinstall`
-- we still want to respect existing versions, we just don't want to
respect _installed_ versions. But now that the installed versions and
preferences are decoupled, we can remove this (`--reinstall` is enforced
on the installed versions via the `Exclusions` struct that we pass to
the resolver).
While I was here, I also cleaned up the lockfile preference code to
better match the structure for `requirements.txt`.
## Summary
This PR just ensures that when running `uv lock` (or `uv run`), we lock
with all extras. When we later install, we'll also _install_ with all
extras, but that will be changed in a future PR.
## Summary
There are a few behavior changes in here:
- We now enforce `--require-hashes` for editables, like pip. So if you
use `--require-hashes` with an editable requirement, we'll reject it. I
could change this if it seems off.
- We now treat source tree requirements, editable or not (e.g., both `-e
./black` and `./black`) as if `--refresh` is always enabled. This
doesn't mean that we _always_ rebuild them; but if you pass
`--reinstall`, then yes, we always rebuild them. I think this is an
improvement and is close to how editables work today.
Closes#3844.
Closes#2695.
Add workspace support when using `-r <path>/pyproject.toml` or `-e
<path>` in the pip interface. It is limited to all-editable
static-metadata workspaces, and tests only include a single main
workspace, ignoring path dependencies in another workspace. This can be
considered the MVP for workspace support: You can create a workspace,
you can install from it, but some options and conveniences are still
missing. I'll file follow-up tickets (support in lockfiles, support path
deps in other workspace, #3625)
There is also support in `uv run`, but we need
https://github.com/astral-sh/uv/issues/3700 first to properly support
using different current projects in the bluejay interface, currently the
resolution and therefore the lockfile depends on the current project.
I'd do this change first (it's big enough already), then #3700, and then
add workspace support properly to bluejay.
Fixes#3404
## Summary
We actually _already_ ignore these (preferences only apply to versions,
not URLs), it just happens later on. This PR thus just avoids crashing.
The behavior is unchanged.
Closes#3822.
When parsing requirements from any source, directly parse the url parts
(and reject unsupported urls) instead of parsing url parts at a later
stage. This removes a bunch of error branches and concludes the work
parsing url parts once and passing them around everywhere.
Many usages of the assembled `VerbatimUrl` remain, but these can be
removed incrementally.
Please review commit-by-commit.
## Summary
Closes https://github.com/astral-sh/uv/issues/3715.
## Test Plan
```
❯ echo "/../test" | cargo run pip compile -
error: Couldn't parse requirement in `-` at position 0
Caused by: path could not be normalized: /../test
/../test
^^^^^^^^
❯ echo "-e /../test" | cargo run pip compile -
error: Invalid URL in `-`: `/../test`
Caused by: path could not be normalized: /../test
Caused by: cannot normalize a relative path beyond the base directory
```
I don't really understand why this only happens on windows clippy and
not on linux too, but as usual, boxing the error variant fixes it.
