This is a fallback mode that we supported when we decided to use PEP 517
builds by default. I can't find a single reference to it on GitHub or in
our issue tracker, so I want to drop support for it as part of v0.3.0.
- Removes "experimental" labels from command documentation
- Removes preview warnings
- Removes `PreviewMode` from most structs and methods — we could keep it
around but I figure we can propagate it again easily where needed in the
future
- Enables preview behavior by default everywhere, e.g., `uv venv` will
download Python versions
This PR migrates uv's use of `chrono` to `jiff`.
I did most of this work a while back as one of my tests to ensure Jiff
could actually be used in a real world project. I decided to revive
this because I noticed that `reqwest-retry` dropped its Chrono
dependency,
which is I believe the only other thing requiring Chrono in uv.
(Although, we use a fork of `reqwest-middleware` at present, and that
hasn't been updated to latest upstream yet. I wasn't quite sure of the
process we have for that.)
In course of doing this, I actually made two changes to uv:
First is that the lock file now writes an RFC 3339 timestamp for
`exclude-newer`. Previously, we were using Chrono's `Display`
implementation for this which is a non-standard but "human readable"
format. I think the right thing to do here is an RFC 3339 timestamp.
Second is that, in addition to an RFC 3339 timestamp, `--exclude-newer`
used to accept a "UTC date." But this PR changes it to a "local date."
That is, a date in the user's system configured time zone. I think
this makes more sense than a UTC date, but one alternative is to drop
support for a date and just rely on an RFC 3339 timestamp. The main
motivation here is that automatically assuming UTC is often somewhat
confusing, since just writing an unqualified date like `2024-08-19` is
often assumed to be interpreted relative to the writer's "local" time.

## Summary
Resolves https://github.com/astral-sh/uv/issues/4537
- First commit avoids overwriting dependencies with different markers.
- Second commit supports adding from requirements files.
## Test Plan
`cargo test`
## Summary
We now persist the `ResolverInstallerOptions` when writing out a tool
receipt. When upgrading, we grab the saved options, and merge with the
command-line arguments and user-level filesystem settings (CLI > receipt
> filesystem).
The loose consensus is that "fetch" doesn't have much meaning and that a
boolean flag makes more sense from the command line.
1. Adds `--allow-python-downloads` (hidden, default) and
`--no-python-downloads` to the CLI to quickly enable or disable
downloads
2. Deprecates `--python-fetch` in favor of the options from (1)
3. Removes `python-fetch` in favor of a `python-downloads` setting
5. Adds a `never` variant to the enum, allowing even explicit installs
to be disabled via the configuration file
## Test plan
I tested this with various `pyproject.toml`-level settings and `uv venv
--preview --python 3.12.2` and `uv python install 3.12.2` with and
without the new CLI flags.
## Summary
I think this seems reasonable... Otherwise, we might not go back to PyPI
to revalidate the list of available versions despite the user passing
`--upgrade`.
## Summary
Resolves#5188. Most of the changes involve creating a new function in
`tool/common.rs` to contain the common functionality previously found in
`tool/install.rs`.
## Test Plan
`cargo test`
```console
❯ ./target/debug/uv tool upgrade black
warning: `uv tool upgrade` is experimental and may change without warning.
Resolved 6 packages in 25ms
Uninstalled 1 package in 3ms
Installed 1 package in 19ms
- black==23.1.0
+ black==24.4.2
Installed 2 executables: black, blackd
```
Following #5869, the documentation has some less-than-helpful
suggestions to use `uv help python` for details — we should link to the
`uv python` section instead.
## Summary
Partially resolves#5561. Haven't added overrides support yet but I can
add it tomorrow if the current approach for constraints is ok.
## Test Plan
`cargo test`
Manually checked trace logs after changing the constraints.
