These crates didn't have any changes until now, when I bumped
the versions of some other crates they depend on:
tor-consdiff
arti-hyper
arti-bench
arti-testing
These crates have had small code changes, but no API additions:
tor-config
tor-socksproto
tor-cert
tor-chanmgr
tor-ptmgr
tor-guardmgr
tor-circmgr
tor-dirclient
tor-dirmgr
arti
tor-hsservice
tor-congestion
These crates have had API extensions:
fs-mistrust
tor-llcrypto
tor-bytes
tor-checkable
tor-linkspec
tor-netdoc
tor-persist
arti-client
These are API breaks, but the crates themselves are currently
100% experimental, so there's no need to bump the minor versions
according to our semver rules.
We now manipulate raw relay cell bodies as (an alias for)
`Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This
enables us to do much less copying. It will become more important
soon, as we defer parsing relay cell bodies even longer.
Related to #7.
We also use SliceWriter to avoid allocating a Vec<> for every relay
message we want to encode, and instead encode directly into the
cell.
Locally, the only functional effect is that now we refuse to handle
non-whole-number-of-minutes lengths - but since the consensus
parameter can't represent those, there's no overall functional change.
There are some places where I note certificates which are not
currently validated, because there is no cryptographic point in
doing so. We should either document that this is okay, or validate
the certificates anyway.
This code might benefit from refactoring to make it prettier.
In !948 we renamed a couple of accessor functions, which is a
breaking change in `tor-cell`'s API.
In retrospect, perhaps we should have deprecated the old names and
added the new ones, so we wouldn't have to break the API. (This is
the only API break AFAICT since 1.1.0.)
These changes influence behavior, but not effect compatibility.
(If I messed up, and any crate except for `arti` has non-breaking
API changes, that's still fine, since they are all version
0.x.)
This logic is a bit tricky, so I've tried to document it and add
fairly good tests. The silver lining is that the external API for
all of this logic will make it invisible and hidden.
There are some cases where I added functions that I think might
eventually get lowered into MdConsensus: But I don't want to lower
too much right now, since the convention for our netdoc accessors is
that they are fairly unsophisticated, and they show you the document
as it is.
Closes#686
This required rewriting some of our error handling code in
command-line processing, since the toml crate now displays and
reports errors differently. (Admittedly, this code still is kind of
ugly, but at least it is nicely hidden.)
This is in lieu of upgrading to the latest base64 crate, which has
a different API from the old one. Since we have to migrate either
way, we might as well use base64ct everywhere.
I don't think that most of these cases _require_ constant-time
base64, but it won't hurt.
These are a bit complex internally, but the API they present is
pretty simple. I've left some discussion of points where the design
isn't totally fleshed out, and where we need to look harder at the
spec.
Part of #716.
On 1.22, cargo audit is complaining about RUSTSEC-2023-0001.
We aren't affected, since we don't use windows named pipes (yet),
but let's make cargo audit happier.
