Well, mostly correct. Our current serde implementation doesn't
tell us much about what went wrong with the object, so we can't
tell why we couldn't convert it into a Request.
Also, our output for the data field is not as the spec says:
we should bring them into conformance.
Part of #825.
It's experimental, and tokio-only. To enable it, build with
the "rpc" feature turned on, and connect to
`~/.arti-rpc-TESTING/PIPE`. (`nc -U` worked for me)
I'll add some instructions.
Per our design, every connection starts out unauthenticated, and
needs one authenticate command to become authenticated.
Right now the only authentication type is "This is a unix named
socket where everybody who can connect has permission."
I'm not sure about these APIs at all! They force us to use
`async_trait` for `tor_rpccmd::Context`, which bothers me. Should we
just have a function that returns
`Option<Box<dyn Sink<Item=X, Error=Y>>` or something? If so,
what's the correct Y?
This code uses some kludges (discussed with Ian previously and
hopefully well documented here) to get a type-identifier for each
type in a const context. It then defines a macro to declare a
type-erased versions of a concrete implementation functions, and
register those implementations to be called later.
We will probably want to tweak a bunch of this code as we move ahead.
Ordinarily you can cancel a future just by dropping it, but we'll
want the ability to cancel futures that we no longer own (because we
gave them to a `FuturesUnordered`).
We have a local alias of `HsDesc = String` which needs to be got rid
of.
But, right now the alternative would be to implement all the code for
signature checking and decryption of an `HsDesc`, before we can make a
test case for the downloader part.
These crates had no changes until just a moment ago. But since
we updated the versions on some of their dependents, they have now
changed themselves. Thus they get patchlevel bumps.
```
tor-rtmock
tor-protover
tor-socksproto
tor-consdiff
tor-chanmgr
tor-dirclient
tor-hsservice
```
For these crates, the changes are nontrivial, so we
_do_ bump the versions on which their dependent crates depend.
Fortunately, since they are all pre-1.0, we don't need to
distinguish semver-additions from other changes. (Except for arti,
which _is_ post-1.0, but gets a patchlevel bump anyway.)
These are unstable crates with breaking changes:
```
tor-hscrypto
tor-hsclient
```
These have new or extended APIs:
```
safelog
tor-bytes
tor-cell
tor-linkspec
tor-llcrypto
tor-proto
tor-cert
arti-client
```
These have new unstable APIs or features:
```
tor-netdoc
tor-circmgr (also broke some unstable APIs)
arti (is post-1.0)
```
These have bugfixes only:
```
caret
tor-dirmgr
```
Their dependents are _not_ updated to a more recent version.
These bumped the version of a dependency that they don't expose
```
tor-rtcompat
fs-mistrust
```
This one had internal refactoring:
```
tor-netdir
```
These had trivial changes only:
```
tor-checkable
tor-ptmgr
tor-guardmgr
arti-hyper
arti-bench
arti-testing
```
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.

This new function combines "sending a message" and "accepting
replies in a stream" into a single call, so that there is no gap
between when the message is sent and the replies are available.
There are a number of compromises here, in order to avoid API
proliferation. I've tried to contain them as best I can.
See comments for additional design discussion.
Explicit drops don't work. Instead, introduce a scope.
We need two scopes, actually: one where we do the initial table
wrangling, and one for the retries after relock.
So we must put the meat in a closure so we can reuse it.
And we must return the flow control as an enum. Bah, etc.
Avoid reformatting this for the moment. This makes the delta legible...
Provide a more cookied "secret keys for use to connecting to a
particular HS" type, with a builder.
This wants to use config stuff, so oughtn't to be in tor-*crypto.
The individual types remain there.
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.)
