Ian Jackson bd41e29f33 tor-basic-utils: Add comment about lack of race
In answer to
  https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/632#note_2822107

I think this is subtle enough that it deserves a comment.

Ian Jackson cb982183f9 arti-client: Do periodic task dormancy in a management task
This means that it is no longer possible to write code which updates
the dormant mode but forgets to notify the periodic tasks.

Ian Jackson 2d3f4493a4 arti-client: Make dormant_mode be an Option, None on drop
This will allow receivers (which we are about to introduce) to
terminate when the last client is dropped.

Ian Jackson bc498bc7a0 arti-client: Provide DropNotifyWatchSender
There are going to be some tasks (well, right away, one task) which
will want to go away when the sender is dropped.

The docs in postage are silent, but postage::Sender does not
have a Drop impl so I don't think we can rely on the Receivers getting
None from their Stream impl.

So we're going to have the watch send Options, which are None only
when the sender is dropped.

Ian Jackson 9146a03533 arti-client: Convert dormant_mode into a postage::watch
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.

Ian Jackson f8170a9c48 arti-client: Add Bug variant to error
We're going to want this in a moment.

Ian Jackson 7acdd21750 Provide maybe_send on postage::Sender, via extension trait
We need to replace the AtomicBool for dormant mode with something that
can wake up tasks.  postage::watch is the right shape.

But we want to be able to update it but suppress no-op updates.
(There is going to be a call site where no-op updates can occur.)

In the absence of a suitable upstream method as requested here
  https://github.com/austinjones/postage-rs/issues/56
we introduce this facility via an extension trait.

Nick Mathewson 9d3beb34a3 Bump tor-dirmgr to version 0.5.1.
This does not require a change in any other crate, since
the change here does not affect tor-dirmgr's APIs.

Nick Mathewson ef76b273a9 circmgr: Refactor DirPathBuilder::pick_path.
We no longer needs to have a "return" at the end of each match
block.

Nick Mathewson 98cda34fb8 netdir: Make pick() functions take FnMut closures.
There's no reason to enforce their being Fn closures, and allowing
them to be FnMut allows us to count which filters make us rejected
given relays.
2022-07-12 11:43:49 -04:00
Nick Mathewson ad87cdcf27 tor-basic-utils: Add a new interface to FilterCount
This interface allows using FilterCount with functions that expect
predicates rather than iterator chains.

I'm about to use it to get meaningful FilterCount results in the
path-selection code in circmgr.

Ian Jackson f098b93d0a tor-persist: StateMgr: vagueify docs about NoLock error
`NoLock` is now a variant of `err::ErrorSource` but that is private.

Nick Mathewson 4dce7557b6 Remove the last vestiges of write_infallible.
Now that everything has been converted to fallible writers, we get
to finally remove write_infallible() from tor_bytes.
2022-07-11 11:18:51 -04:00
Nick Mathewson fbb6484025 tor-proto: Stop using write_infallible in handshake code.
This change was a bit annoying, since most of this code _can't_ fail,
and so the only reasonable response is to wrap the input in an
internal error... except for one case where we're actually encoding
a caller-provided message, so we _do_ want to wrap the EncodeError
from tor_bytes.
2022-07-11 11:18:51 -04:00
Nick Mathewson 44314f5076 tor-cell: Stop using write_infallible
Also, stop using "expect" and "assert!" to check for errors.

Nick Mathewson 2367f92c2c tor-cert: Encoding now uses Writeable trait.
This lets us remove a few TODOs.
2022-07-11 11:18:51 -04:00
Nick Mathewson 9b02cf004c tor-bytes::impls: Remove usage of infallible writers. 2022-07-11 11:18:51 -04:00
Nick Mathewson 9ca301faee socksproto: Use fallible writers.
Also, make private a function that had formerly been `pub`.
2022-07-11 11:18:51 -04:00
Nick Mathewson 5a61a6d73a Remove "write_and_consume_infallible".
There were only a few of these.  Removing it required porting
everything to use `write_and_consume` instead, and handling its
(potential) errors.
2022-07-11 11:18:51 -04:00
Nick Mathewson 8810af7f65 Convert each write_onto_infallible implementation into write_onto. 2022-07-11 11:18:51 -04:00
Nick Mathewson e1337bee8f Convert each write_into_infallible implementation into write_into.
(There was only one.)
2022-07-11 11:18:51 -04:00
Nick Mathewson 26c81edeea Define new write_into and write_onto methods with correct APIs. 2022-07-11 11:18:51 -04:00
Nick Mathewson 7938f65c66 Rename "write" methods on tor-bytes to "write_infallible".
This comprises four renames:

```
write_onto -> write_onto_infallible
write_into -> write_into_infallible
write -> write_infallible
writer_and_consume -> write_and_consume_infallible.
```

The rest of this branch will be concerned with replacing these
`_infallible` methods with ones that return a `Result`.  This is
part of #513.
