This gets rid of many Result(). Many parameters are renamed.
Test cases of the now-impossible branch are removed.
Deleting the match from padding_parameters will come in a moment.
I've split off that commit since it has much whitespace noise.
for now, change the error type to Void.
The chanmgr remembers the last dormancy state it was told.
We invent a chanmgr-specific Dormancy which the arti-client code knows
how to convert from the richer top-level dormant status. This avoids
having to have everyone know all the variants of the top-level state.
To call reconfigure_general, we must also obtain and plumb through a
netdir. Right now we must return an internal error if there is in
fact no netdir, because reconfigure_general does not yet cope with a
missing netdir.
Nothing actually *uses* the dormancy yet.
We're going to need to reuse this, so we can plumb the dormancy to
more places. Breaking it out avoids having repeat the initial
dormancy value in two places.
Do _not_ bump the dependency versions on crates that have had no
changes since arti 0.0.5, since those crates do not depend on the
new APIs.
```
cargo set-version -p tor-basic-utils --bump patch
cargo set-version -p tor-llcrypto --bump patch
git restore crates/tor-checkable
git restore crates/tor-consdiff
git restore crates/tor-rtmock
```
This performs the transitive closure of the last operation:
everything that depends on a crate with a breaking change gets the
version which it depends on bumped.
```
cargo set-version -p tor-proto --bump minor
cargo set-version -p tor-netdoc --bump minor
cargo set-version -p arti-hyper --bump minor
cargo set-version -p arti-bench --bump minor
cargo set-version -p arti-testing --bump minor
cargo set-version -p tor-config --bump minor
```
This allows us to give better errors in the case where bootstrapping
succeeds at first, but fails thereafter for long enough to make our
directory expire.
This name is more accurate because we aren't only dealing with
clock skew here: we're also trying to tolerate the case where the
authorities fail to reach consensus for a while.
This logic can now be adjusted via the config object so that it does
its own overriding by looking at the environment as appropriate.
Removing these methods helps simplify the code a bit.
Enabled by #483.
We are going to want to be able to wake up other tasks elsewhere in
Arti, that need to know about dormancy. We will give them a postage
watch Receiver.
Right now there are no such things yet.
Found these by disabling the nightly dbg macro special case. Now, we
have a mechanism for globally adding suppressions to tests, we can use
that instead.
According to doc/Errors.md, and in keeping with current best
practices, we should not include display an error's `source()` as
part of that error's display method. Instead, we should let the
caller decide to call source() and display that error in turn.
Part of #323.
Rustls uses ring, which uses code from BoringSSL, which derived from
OpenSSL before OpenSSL changed their license. So ring is currently
under 3BSD/SSLEay licenses, which aren't GPL-compatible, which may
be a problem for some people.
See #493.
A "reset" happens whenever we have to start a download attempt over
-- either because we ran out of retries, or we found something wrong
with the consensus after fetching certificates.
An "error" happens when we have a recoverable error from one or more
directory sources.
A "stall" happens whenever a round of downloads or cache loads leads
to no change in the status.
We don't yet use this as part of our status reporting.
These need to be optional: they improve performance by shifting to
asm implementations, which may not be everybody's idea of good practice.
These are not 'pure' features, since they select one implementation
but disable another. Therefore they don't go in `full`.
Closes#441.
This change also means that we need to create the handle and scheduler
earlier in the process of creating the DirMgr. If we don't, we won't
have a way to manage the task before bootstrap() returns.
The "full" feature is a catch-all for all features, _except_:
* Those that select a particular implementation (like
tor-llcrypto/with-openssl) or build flag (like "static")
* Those that are experimental or unstable (like "experimental-api")
* Those that are testing-only.
This will make it much more convenient for code that only wants one of
these traits (or a subset of them). This is a good thing to support
because it will allow us to use a ZST in places that do not need an
actual async runtime handle (typically, the runtime handle is needed
only for spawn).
Previously it was the job of a task in CircMgr to do this; but we're
going to want to give GuardMgr full access to the latest NetDir for
this, and for other code-simplification reasons.
With this change I'm deprecating a couple of functions in
tor-circmgr. It's no longer necessary for us to have an artificial
external way for you to feed new NetDirs to a circmgr. (I could
just remove them, but I want practice deprecating.)
