The guard manager is responsible for handing out the first hops of
tor circuits, keeping track of their successes and failures, and
remembering their states. Given that, it makes sense to store this
information here. It is not yet used; I'll be fixing that in
upcoming commits.
Arguably, this information no longer belongs in the directory
manager: I've added a todo about moving it.
This commit will break compilation on its own in a couple of places;
subsequent commits will fix it up.
This is a revised version of !397; it implements a scheduling system for
periodic tasks that can be externally controlled, and then uses the
external control aspect to implement a basic dormant mode (#90).
More technically, the scheduling system consists of a `Stream` that
periodic tasks are expected to embed in a `while` loop or similar, a
way for tasks themselves to choose how long to wait until the stream
next yields a result, and a handle to control this outside of the task.
Now we use NetParams. That implies making its constructor public,
which I think it fine.
This is related to #413 but is far from completing that ticket.
This has the different syntax for builder field attributes than what I
originally proposed in my MR, and which therefore is in the pinned
branch.
My upstream MR for the field attributes feature was morged:
https://github.com/colin-kiegel/rust-derive-builder/issues/239
This has the humantime_serde::option module, which we have upstreamed
and are about to switch to.
The remaining dependency with version = "1" is going to be removed
in a moment.
We are going to want to specify custom attributes on fields of the
builder struct. This feature was missing from derive_builder.
This commitid is the current head of my MR branch
https://github.com/colin-kiegel/rust-derive-builder/pull/237https://github.com/ijackson/rust-derive-builder/tree/builder-field-attrs
Using the commitid prevents surprises if that branch is updated.
We will require this newer version of derive_builder. The version
will need to be bumped again later, assuming the upstream MR is merged
and upstream do a release containing the needed changes.
This is the first one where anyhow::Error impl AsRef<dyn StdError>
We want this because we want to add error reporting functionality
which works with all kinds of errors, which means we need an
anyhow::Error which can be vieweed as a StdError.
(The alternative would be to deref at the call sites of
report_and_exit, making it less ergonomic.)
anyhow 1.0.23 is from November 2019.
The new `BootstrapBehavior` enum controls whether an unbootstrapped
`TorClient` will bootstrap itself automatically (`Ondemand`) when an
attempt is made to use it, or whether the user must perform
bootstrapping themselves (`Manual`).
The `lazy-init` example shows how you could write a simple
`get_tor_client()` function that used a global `OnceCell` to share
a Tor client across an entire application with this API.
closes arti#278
Since the only purpose of this function is to make sure that no
bootstrapping task is running, a simple futures:🔒:Mutex
should do the job just fine.
Closes#337.
This commit changes how the `TorClient` type works, enabling it to be
constructed synchronously without initiating the bootstrapping process.
Daemon tasks are still started on construction (although some of them
won't do anything if the client isn't bootstrapped).
The old bootstrap() methods are now reimplemented in terms of the new
create_unbootstrapped() and bootstrap_existing() methods.
This required refactoring how the `DirMgr` works to enable the same sort
of thing there.
closes#293
This commit puts the native-tls crate behind a feature. The feature
is off-by-default in the tor-rtcompat crate, but can be enabled
either from arti or arti-client.
There is an included script that I used to test that tor-rtcompat
could build and run its tests with all subsets of its features.
Closes#300
The purpose of a this API is to tell the user how far along Arti is
in getting bootstrapped, and if it's stuck, what it's stuck on.
This API doesn't yet expose any useful information: by the time it's
observable to a client, it's always "100% bootstrapped." But I'm
putting it in a MR now so that we can review the basic idea, and to
avoid conflicts with later work on tickets like #293 and #278.
This is part of #96.
I found these versions empirically, by using the following process:
First, I used `cargo tree --depth 1 --kind all` to get a list of
every immediate dependency we had.
Then, I used `cargo upgrade --workspace package@version` to change
each dependency to the earliest version with which (in theory) the
current version is semver-compatible. IOW, if the current version
was 3.2.3, I picked "3". If the current version was 0.12.8, I
picked "0.12".
Then, I used `cargo +nightly upgrade -Z minimal-versions` to
downgrade Cargo.lock to the minimal listed version for each
dependency. (I had to override a few packages; see .gitlab-ci.yml
for details).
Finally, I repeatedly increased the version of each of our
dependencies until our code compiled and the tests passed. Here's
what I found that we need:
anyhow >= 1.0.5: Earlier versions break our hyper example.
async-broadcast >= 0.3.2: Earlier versions fail our tests.
async-compression 0.3.5: Earlier versions handled futures and tokio
differently.
async-trait >= 0.1.2: Earlier versions are too buggy to compile our
code.
clap 2.33.0: For Arg::default_value_os().
coarsetime >= 0.1.20: exposed as_ticks() function.
curve25519-dalek >= 3.2: For is_identity().
generic-array 0.14.3: Earlier versions don't implement
From<&[T; 32]>
httparse >= 1.2: Earlier versions didn't implement Error.
itertools at 0.10.1: For at_most_once.
rusqlite >= 0.26.3: for backward compatibility with older rustc.
serde 1.0.103: Older versions break our code.
serde_json >= 1.0.50: Since we need its Value type to implement Eq.
shellexpand >= 2.1: To avoid a broken dirs crate version.
tokio >= 1.4: For Handle::block_on().
tracing >= 0.1.18: Previously, tracing_core and tracing had separate
LevelFilter types.
typenum >= 1.12: Compatibility with rust-crypto crates
x25519-dalek >= 1.2.0: For was_contributory().
Closes#275.
To do this at all neatly, I had to split out `tor-config` from
`arti-config` again, and putting the lower level stuff (paths,
builder errors) into tor-config. I also changed our use of
derive_builder to always use a common error type, to avoid
error type proliferation.
