Filter out source dists and wheels whose `requires-python` from the
simple api is incompatible with the current python version.
This change showed an important problem: When we use a fake python
version for resolving, building source distributions breaks down because
we can only build with versions we actually have.
This change became surprisingly big. The tests now require python 3.7 to
be installed, but changing that would mean an even bigger change.
Fixes#388
## Summary
Closes https://github.com/astral-sh/puffin/issues/390.
## Test Plan
Installed `jupyter_core==5.5.0`, then removed the `jupyter_core` and
`jupyter_core-5.5.0.dist-info` directories from my virtualenv manually,
but left `jupyter.py`. I then re-ran `puffin pip-compile`, and verified
that it errored on `main` but succeeded here.
This copies the allocator configuration used in the Ruff project. In
particular, this gives us an instant 10% win when resolving the top 1K
PyPI packages:

I was moved to do this because I noticed `malloc`/`free` taking up a
fairly sizeable percentage of time during light profiling.
As is becoming a pattern, it will be easier to review this
commit-by-commit.
Ref #396 (wouldn't call this issue fixed)
-----
I did also try adding a `smallvec` optimization to the
`Version::release` field, but it didn't bare any fruit. I still think
there is more to explore since the results I observed don't quite line
up with what I expect. (So probably either my mental model is off or my
measurement process is flawed.) You can see that attempt with a little
more explanation here:
https://github.com/astral-sh/puffin/commit/f9528b4ecd1b0c260df7e8ad57b9ddc4da09d273
In the course of adding the `smallvec` optimization, I also shrunk the
`Version` fields from a `usize` to a `u32`. They should at least be a
fixed size integer since version numbers aren't used to index memory,
and I shrunk it to `u32` since it seems reasonable to assume that all
version numbers will be smaller than `2^32`.

## Summary
It looks like, when you install `pip`, it includes a bunch of
`__pycache__` directories in the RECORD file (although these directories
don't exist until you run `pip`). Our uninstaller assumed that the
RECORD file only contained _files_.
Closes https://github.com/astral-sh/puffin/issues/389.
I intend this to become the main form of caching for puffin: You can
make http requests, you tranform the data to what you really need, you
have control over the cache key, and the cache is always json (or
anything else much faster we want to replace it with as long as it's
serde!)
## Summary
This PR refactors our `RemoteDistribution` type such that it now follows
a clear hierarchy that matches the actual variants, and encodes the
differences between source and built distributions:
```rust
pub enum Distribution {
Built(BuiltDistribution),
Source(SourceDistribution),
}
pub enum BuiltDistribution {
Registry(RegistryBuiltDistribution),
DirectUrl(DirectUrlBuiltDistribution),
}
pub enum SourceDistribution {
Registry(RegistrySourceDistribution),
DirectUrl(DirectUrlSourceDistribution),
Git(GitSourceDistribution),
}
/// A built distribution (wheel) that exists in a registry, like `PyPI`.
pub struct RegistryBuiltDistribution {
pub name: PackageName,
pub version: Version,
pub file: File,
}
/// A built distribution (wheel) that exists at an arbitrary URL.
pub struct DirectUrlBuiltDistribution {
pub name: PackageName,
pub url: Url,
}
/// A source distribution that exists in a registry, like `PyPI`.
pub struct RegistrySourceDistribution {
pub name: PackageName,
pub version: Version,
pub file: File,
}
/// A source distribution that exists at an arbitrary URL.
pub struct DirectUrlSourceDistribution {
pub name: PackageName,
pub url: Url,
}
/// A source distribution that exists in a Git repository.
pub struct GitSourceDistribution {
pub name: PackageName,
pub url: Url,
}
```
Most of the PR just stems downstream from this change. There are no
behavioral changes, so I'm largely relying on lint, tests, and the
compiler for correctness.
This PR tweaks the representation of `Tags` in order to offer a
faster implementation of `WheelFilename::is_compatible`. We now use a
nested map of tags that lets us avoid looping over every supported
platform tag. As the code comments suggest, that is the essential gain.
We still do not mind looping over the tags in each wheel name since they
tend to be quite small. And pushing our thumb on that side of things can
make things worse overall since it would likely slow down WheelFilename
construction itself.
For micro-benchmarks, we improve considerably for compatibility
checking:

We do regress slightly on the time it takes for `Tags::new` to run, but
this is somewhat expected. And in absolute terms, 114us is perfectly
acceptable given that it's only executed ~once for each `puffin`
invocation.
Ad hoc benchmarks indicate an overall 25% perf improvement in `puffin
pip-compile` times. This roughly corresponds with how much time
`is_compatible` was taking. Indeed, profiling confirms that it has
virtually disappeared from the profile.
Fixes#157
## Summary
Low-priority but fun thing to end the day. You can now pass
`--target-version py37`, and we'll generate a resolution for Python 3.7.
See: https://github.com/astral-sh/puffin/issues/183.
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'
pygraphviz/graphviz_wrap.c:3020:10: fatal error: graphviz/cgraph.h: No such file or directory
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`
By default, we will build source distributions for both resolving and
installing, running arbitrary code. `--no-build` adds an option to ban
this and only install from wheels, no source distributions or git builds
allowed. We also don't fetch these and instead report immediately.
I've heard from users for whom this is a requirement, i'm implementing
it now because it's helpful for testing.
I'm thinking about adding a shared `PuffinSharedArgs` struct so we don't
have to repeat each option everywhere.
Closes https://github.com/astral-sh/puffin/issues/356.
The example from the issue now renders as:
```
❯ cargo run --bin puffin-dev -q -- resolve-cli tensorflow-cpu-aws
puffin-dev failed
Caused by: No solution found when resolving build dependencies for source distribution:
Caused by: Because there is no available version for tensorflow-cpu-aws and root depends on tensorflow-cpu-aws, version solving failed.
```
This was dumb of me. We pass out indexes when adding progress bars, but
were then removing entries on completion, so any outstanding indexes
were now _invalid_. We just shouldn't remove them. The `MultiProgress`
retains a reference anyway, IIUC.
Closes https://github.com/astral-sh/puffin/issues/360.
Rejigger Linux platform detection
This change makes some very small improvements to the Linux platform
detection logic. In particular, the existing logic did not work on my
Archlinux machine since /lib64/ld-linux-x86-64.so.2 isn't a symlink. In
that case, the detection logic should have fallen back to the slower
`ldd --version` technique, but `read_link` fails outright when its
argument isn't a symbolic link. So we tweak the logic to allow it to
fail, and if it does, we still try the `ldd --version` approach instead
of giving up completely.
I also made some cosmetic improvements to the regex matching, as well as
ensuring that the regexes are only compiled exactly once.
We now write the `direct_url.json` when installing, and _skip_
installing if we find a package installed via the direct URL that the
user is requesting.
A lot of TODOs, especially around cleaning up the `Source` abstraction
and its relationship to `DirectUrl`. I'm gonna keep working on these
today, but this works and makes the requirements clear.
Closes#332.
mastodon-py 1.5.1 uses a dot in its dist-info dir name, which we

`direct_url.json`. We're not actually taking advantage of it yet (or
wiring it through) in Puffin.
