`clippy::collapsible_if` started triggering after bumping the MSRV to
1.88.
Since this triggers from a lot of places, and since there even are a
couple of instances where we explicitly allow `clippy::collapsible_ifs`,
I've opened #2342 for deciding what to do about it.

This adds the lint to all our crates.

Make this whole module conditional on the encode feature.
Apply the derives. Provide the necessary manual implementations for
the types where we use `with`.
|
| | |
|
| |
|
|
| |
Now we use all the imports. We're still adding much code, though.
|
| |
|
|
|

Adding these all at the beginning helped me with churn in this branch.
The allow(unused) will go away again shortly.

We're going to use this for the encoder testing too, so it needs to be
not buried inside parse2.
This commit is the file rename plus minimal changes to make it compile.
|
| |
|
|
|
| |
My planned new derive for encoding will be pub, but cfg gated, like
parse2 is.
|

|

My planned encoding derive macro is going to provide keywords as
literal strings.
(The purpose of this trait is to allow the old parser to be generic
over its keyword constants, not to provide type-safety against passing
non-keyword strings to document encoders. Such bugs aren't very
likely and will be especially unlikely when we're deriving encoders.)
|
| |
|
|
|
| |
My planned encoding derive macro is not going to use `decl_keyword!`
but will need to call `NetdocEncoder::item`.
|
| |
|
|
|
|
|
| |
We're going to introduce facilities for encoding more generally, and
we'll want a way to enable them.
Instead, have a separate feature for *encoding* documents.
|
| |
|
|
|
| |
The word "build" so often in Rust means builder pattern. This module
contains functions for encoding.

Since 9ce85acb3ab0d1a0b1be6ef0f10707983f4362a3
tor-netdoc: replace impl_item_argument_as_display with NormalItemArgument
this trait impl has implications for encoding as well as parsing.
|
| |
|
|
|
| |
This is currently used to enable `parse2::ItemArgumentParseable`.
In a moment it will enable `build::ItemArgument` too.
|
| |
|
|
| |
This feature has been removed from nightly, in favor of doc_cfg.
|
| |
|
|
|
| |
This is needed if we want to use these macros in `doc`, which we're
going to.
|
| |
|
|
|
| |
This isn't used anywhere yet. We're going to demonstrate it, and test
the demo, in a moment.

Part of #1849.
Note that these functions are distributed across crates,
so that if (in the future) we stop doing API breaks
with every release, we will get the right outputs.
Note also that these functions build the list of protocols
out of specific symbolic features, rather than numbers:
this makes it easier to avoid errors about "which feature was
Relay=4 again", and easier to avoid accidentally referring to a
protocol that doesn't exist, like "Consensus" (should be "Cons")
or "HsDir" (case is wrong).

In 1.83, this warning triggers on many of our crates.
We're thinking of fixing them all, but for now,
we're going to disable the warning.
This is part of #1765.

Now
cargo check --workspace --no-default-features --all-targets
cargo build -p arti --no-default-features --features=memquota,tokio,native-tls
are both clean.

`ParseErrorSource` was originally meant to represent a parsing error,
this enum has since gained some variants that aren't really parsing
related (`Signature`, `CertSignature`, `UntimelyDescriptor`).
Since this error type is now used for general-purpose netdoc errors,
let's rename `ParseError{Kind, Source}` to `NetdocError{Kind, Source}`.

`NetdocText` is a wrapper around a `String` and a type marker. The type
annotation proved of limited use, and made the netdoc builder API
somewhat awkward to use.

This introduces the `NetdocBuilder` trait described in
`netdoc-builder.md` and a new `tor-netdoc::doc::hsdesc::build` module,
which exports the `HsDescBuilder`. Hidden services will use
`HsDescBuilder` to build and encode hidden service descriptors.
There are several TODOs in the code that I'm planning to address
separately.
Partially addresses #745.

Fixes #756

There will be two call sites to demonstrate it.
Eventually maybe this will want to be in tor-basic-utils, since it
doesn't depend on any of the tor-netdoc types. But it would be
sensible to wait until the situation with PeekableIterator and
Itertools is improved.
For now we make this #[doc(hidden)] to avoid it becoming part of our
stable API.

This warning kind of snuck up on us! (See #748) For now, let's
disable it. (I've cleaned it up in a couple of examples, since
those are meant to be more idiomatic and user-facing.)
Closes #748.

Apparently cargo fmt doesn't like these, which my perl rune didn't
delete.
This commit is precisely the result of `cargo fmt`.

The feature we want is `#[doc = include_str!("README.md")]`, which is
stable since 1.54 and our MSRV is now 1.56.
This commit is precisely the result of the following Perl rune:
perl -i~ -0777 -pe 's{(^//!(?!.*\@\@).*\n)+}{#![doc = include_str!("../README.md")]\n}m' crates/*/src/lib.rs

This was the result of:

This lint is IMO inherently ill-conceived.
I have looked for the reasons why this might be thought to be a good
idea and there were basically two (and they are sort of contradictory):
I. "Calling ‘.clone()` on an Rc, Arc, or Weak can obscure the fact
that only the pointer is being cloned, not the underlying data."
This is the wording from
https://rust-lang.github.io/rust-clippy/v0.0.212/#clone_on_ref_ptr
It is a bit terse; we are left to infer why it is a bad idea to
obscure this fact. It seems to me that if it is bad to obscure some
fact, that must be because the fact is a hazard. But why would it be
a hazard to not copy the underlying data ?
In other languages, faliing to copy the underlying data is a serious
correctness hazard. There is a whose class of bugs where things were
not copied, and then mutated and/or reused in multiple places in ways
that were not what the programmer intended. In my experience, this is
a very common bug when writing Python and Javascript. I'm told it's
common in golang too.
But in Rust this bug is much much harder to write. The data inside an
Arc is immutable. To have this bug you'd have use interior mutability
- ie mess around with Mutex or RefCell. That provides a good barrier
to these kind of accidents.
II. "The reason for writing Rc::clone and Arc::clone [is] to make it
clear that only the pointer is being cloned, as opposed to the
underlying data. The former is always fast, while the latter can
be very expensive depending on what is being cloned."
This is the reasoning found here
https://github.com/rust-lang/rust-clippy/issues/2048
This is saying that *not* using Arc::clone is hazardous.
Specifically, that a deep clone is a performance hazard.
But for this argument, the lint is precisely backwards. It's linting
the "good" case and asking for it to be written in a more explicit
way; while the supposedly bad case can be written conveniently.
Also, many objects (in our codebase, and in all the libraries we use)
that are Clone are in fact simply handles. They contain Arc(s) (or
similar) and are cheap to clone. Indeed, that is the usual case.
It does not make sense to distinguish in the syntax we use to clone
such a handle, whether the handle is a transparent Arc, or an opaque
struct containing one or more other handles.
Forcing Arc::clone to be written as such makes for code churn when a
type is changed from Arc<Something> to Something: Clone, or vice
versa.
