I followed the following procedure to make these changes:
* I used maint/changed_crates to find out which crates had changed
since 0.3.0.
* I used grep and maint/list_crates to sort those crates in
topological (dependency) order.
* I looked through semver_status to find which crates were listed as
having semver-relevant changes (new APIs and breaking changes).
* I scanned through the git logs of the crates with no
semver-relevant changes listed to confirm that, indeed, they had
no changes. For those crates, I incremented their patch-level
version _without_ changing the version that other crates depend on.
* I scanned through the git logs of the crates with no
semver-relevant changes listed to confirm that, indeed, they had
no obvious breaking changes.
* I treated all crates that depend on `arti` and/or `arti-client` as
having breaking changes.
* I identified crates that depend on crates that have changed, even
if they have not changed themselves, and identified them as having
a non-breaking change.
* For all of the crates, I used `cargo set-version -p $CRATE --bump
$STATUS` (where `STATUS` is `patch` or `minor`) to update the
versions, and the depended-upon versions.
These crates had only clippy fixes that do not affect their
behavior:
tor-bytes
tor-cell
tor-events
tor-linkspec
tor-netdir
tor-socksproto
This crate only had the cargo-husky dependency removed, which
does not affect compatibility:
tor-llcrypto
Since these changes have no compatibility effects, it is not
necessary to bump the versions of these crates which other crates
depend on.
We support all of the following (in TOML notation):
```
user = "rose" # by name
user = 413 # by ID
user = false # no user
user = ":current" # A 'special' user.
user = { name: "rose" }
user = { id: 413 }
user = { special: ":none" }
user = { special: ":current" }
```
This is a general-purpose implementation of the ad-hoc approach
currently taken in (eg) crates/tor-proto/src/channel/reactor.rs,
with an API intended to defned against the more obvious mistakes.
This allows us to separate the two concerns: the channel reactor can
focus on handling channel cells and control messages and is over 2.5x
shorter.
The complexity of the manual sink implementation, and the machinery
needed to avoid having to suspend while holding an item, are dealt
with separately. That separate implemenation now has proper
documentation. (Tests are in the nest commit to avoid this one being
even more unwieldy.)
We use `extend` to define this as an extension trait. A competitor is
`ext` but in my personal projects I have found `extend` slightly
better.
Generally, change the paths that mention the crate name to go via a
module-level "use".
This involves adding tor-config as a direct dependency for a few
crates.
This is a benchmarking tool, and fs-mistrust doesn't like the
permissions in our CI. The env var ARTI_FS_DISABLE_PERMISSION_CHECKS
is (of course) specific to arti. Maybe it should be honoured here,
or this should be done via the config files.
But disabling this is fine for now.
A build script reaching into your .git/hooks/ and modifying them
nonconsensually was a bit of a horrifying concept, and also made it hard
to build arti with the feature disabled. Remove this crate, and replace
it with manual instructions on how to install the hooks in
CONTRIBUTING.md.
- The additional parameters passed to GetConsensusState are now passed
through all the states, and used as well.
- WriteNetDir doesn't have a now() or config() method any more, since
the states now get this from the runtime or the config parameters.
- This required modifying the tests to make a mocked runtime and custom
config directly, instead of using DirRcv for this purpose.
- Additionally, because we don't have to upgrade a weak reference for
DirState::dl_config(), that function no longer wraps its return value
in Result.
- (A bunch of the FIXMEs from the previous commit that introduced the
additional parameters have now been rectified as a result.)
Relay nicknames are always between 1 and 19 characters long, and
they're always ASCII: That means that storing them in a [u8;19] will
always be possible, and always use less resources than storing them
in a String.
Fortunately, the tinystr crate already helps us with this kind of
thing.
This is derived from the environment, not the configuration file: We
might not want to trust the configuration file until we've decided
whether we like its permissions.
For reference, the git source for this crate (and the others in its
workspace) currently lives in my personal github account (ijackson).
If this fork turns out to be long-lived and gains features and/or
users, it would be good to move it to a gitlab somewhere.
I have granted Nick crate ownership on the crates.io system.
This is a rough first-cut of an API that I think might help us with
keeping limited categories of sensitive information out of our logs.
I'll refine it based on experiences with using it.
This allows us to use this with an item builder type which doesn't
impl Default. (Obviously this only makes sense for items which aren't
actually builders.)
Document that this can contain either a string for expansion, or a
literal PathBuf not for expansion.
Rename the `from_path` method to `new_literal`: a very important
difference is whether it gets expanded - less important than the Rust
type. Also, now it takes `Into<PathBuf>`, which avoids a needless
clone.
(We don't change the API in `arti-client` because
`&tempfile::Tempdir()` doesn't implement `Into<PathBuf>`, so
`arti-client` has to have some new `as_ref` calls.)
Provide accessors `as_unexpanded_str` and `as_literal_path`. The
deserialisation already makes this part of the stable API,l so not
pvoding accessors seems just obstructive. They are useful for tests,
too.
Add tests for the new entrypoints, and for deserialisation of both
variants from TOML (via config, or directly) and JSON.
This required a bit of poking through the `users` crate, to mess
with the user and group dbs. The original goal was to "trust the
group with the same name as us", but it turned into a bit of a
production, since:
* We want to take our own name from $USER, assuming that matches
our uid. (Otherwise we want to ask getpwuid_r().)
* We only want to trust the group if we are actually a member of
that group.
* We want to cache this information.
* We want to test this code.
This crate is meant to solve #315 by giving a way to make sure that
a file or directory is only accessible by trusted users. I've tried
to explain carefully (in comments and documentation) what this crate
is doing and why, under the assumption that it will someday be read
by another person like me who does _not_ live and breathe unix file
permissions. The crate is still missing some key features, noted in
the TODO section.
It differs from the first version of the crate by taking a more
principled approach to directory checking: it emulates the path
lookup process (reading symlinks and all) one path change at a time,
thus ensuring that we check every directory which could enable
an untrusted user to get to our target file, _or_ which could
enable them to get to any symlink that would get them to the target
file.
The API is also slightly different: It separates the `Mistrust`
object (where you configure what you do or do not trust) from the
`Verifier` (where you set up a check that you want to perform on a
single object). Verifiers are set up to be a bit ephemeral,
so that it is hard to accidentally declare that _every_ object
is meant to be readable when you only mean that _some_ objects
may be readable.
The `[patch]` approach causes the tree not to build when used as a
dependency, unless the `[patch]` is replicated into the depending
project.
Instead, replace our `derive_builer =` dependencies with a reference
to a specific git commit:
perl -i~ -pe 'next unless m/^derive_builder/; s#"(0\.11\.2)"#{ version = "$1", git = "https://github.com/ijackson/rust-derive-builder", rev = "ba0c1a5311bd9f93ddf5f5b8ec2a5f6f03b22fbe" }#' crates/*/Cargo.toml
Note that the commitid has changed. This is because derive_builder is
in fact a workspace of 4 crates. 3 of them are of interest to arti
itself (the 4th exists only for testing). So the same "add git
revision" treatment had to be done to the `derive_builder` and
`derive_builder_macro` crates. Each dependency edge involves a new
commit in the derive_builder workspace, since we can't create a git
commit containing its own commitid. (We want to use commits, rather
than a branch, so that what we are depending on is actually properly
defined, and not subject to the whims of my personal github
namespace.)
There are no actual code changes in derive_builder.
Now that we require Rust 1.56, we can upgrade to AES 0.8. This
forces us to have some slight API changes.
We require cipher 0.4.1, not cipher 0.4.0, since 0.4.0 has
compatibility issues with Rust 1.56.
