* | Merge branch 'error-report' into 'main'Nick Mathewson2022-02-222-3/+9
|\ \ | |/ |/| | | | | Improve error messages from arti cli See merge request tpo/core/arti!331
| * Bump anyhow minimal version to 1.0.23Ian Jackson2022-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the first one where anyhow::Error impl AsRef<dyn StdError> We want this because we want to add error reporting functionality which works with all kinds of errors, which means we need an anyhow::Error which can be vieweed as a StdError. (The alternative would be to deref at the call sites of report_and_exit, making it less ergonomic.) anyhow 1.0.23 is from November 2019.

* | arti: create TorClient first, then bootstrap.Nick Mathewson2022-02-151-4/+3
|/ | | | | | | | | | This change is possible now that #293 is done. As an immediate benefit, it allows us to start monitoring the configuration files immediately, and not only after we're done bootstrapping the client. Closes #336.
* Change deny(clippy::all) to warn(clippy::all).Nick Mathewson2022-02-141-1/+1
| | | | Closes #338.

| * Allow creating unbootstrapped `TorClient`s (and `DirMgr`s)eta2022-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes how the `TorClient` type works, enabling it to be constructed synchronously without initiating the bootstrapping process. Daemon tasks are still started on construction (although some of them won't do anything if the client isn't bootstrapped). The old bootstrap() methods are now reimplemented in terms of the new create_unbootstrapped() and bootstrap_existing() methods. This required refactoring how the `DirMgr` works to enable the same sort of thing there. closes #293
* | Try to resolve the "Truncated" error in tor-socksprotoNick Mathewson2022-02-111-3/+3
|/ | | | | I'm not in love with this solution; the others just seem a bit ugly too.
* Make the Error detail type non-exported from arti-clientNick Mathewson2022-02-041-3/+3
| | | | | | | | | | | At least by default, we should have Error be private, and not expose it as part of our APIs. To keep functionality in `arti`, I had to add an `ExitTimeout` error kind. For interface consistency, I also re-exported ErrorKind and HasError from `arti_client`.

* Merge branch 'ticket270' into 'main'Nick Mathewson2022-02-033-13/+227
|\ | | | | | | | | | | | | Watch configuration files and reload them when they change Closes #270 See merge request tpo/core/arti!280
| * Document that `notify` behavior is strange with symlinksNick Mathewson2022-02-031-0/+5
| | | | | | | | | | | | | | | | | | | | (More specifically, `notify` behaves differently on different platforms. On some, it can watch specific directory objects on the filesystem, and so it only notices when _those_ directories change. If you change a symlink so that the canonical configuration file location is now in some other directory, `notify` won't notice. But on other platforms, notify just does "stat()" in a loop. On those, it _will_ notice if the configuration file changes.)
| * Avoid a potential infinite loop in configuration-watchingNick Mathewson2022-02-031-2/+5
| | | | | | | | | | | | | | | | | | | | | | Since the user can put their logfiles and configuration files in the same directory, writing to the log can trigger an event from `notify`. If we log every non-interesting event from `notify`, then we'll trigger the logs every time we log, and fill up the disk. This commit removes the offending log and adds a comment about why. If we someday decide we do need to log here, maybe we can rate-limit the messages or something.
| * Treat rescan events as meaning "reload configuration".Nick Mathewson2022-02-031-2/+2

| * Add a couple of TODOs about configuration-watching.Nick Mathewson2022-02-021-0/+7
| |
| * Before reloading configuration, drain all pending file changesNick Mathewson2022-02-021-0/+8
| | | | | | | | | | This way, if there are a bunch of changes at once, we only reload one time.
| * Refactor file-watching code to watch parent directories.Nick Mathewson2022-02-021-8/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | Due to limitations in notify and the OS APIs it uses, it isn't actually so useful to watch a single file. Instead, we have to watch the directories that contain the files, and filter out any events that aren't about the specific files we care about. I've put the logic here into a new type, but I've left the type un-exported: its API is pretty ugly, inasmuch as the caller needs to jump through hoops to only get the events that they want. That's not too bad so long as the API is private, but we'd want better if we were exposing this.

| * Detect changes in non-client configuration sections tooNick Mathewson2022-02-012-17/+30
| | | | | | | | We don't yet do much with these, but we can avoid discarding them.
| * Make configuration-watching configurable and off-by-default.Nick Mathewson2022-02-011-2/+11
| | | | | | | | | | | | | | | | I'm slightly concerned about whether this is behavior people would expect to have on-by-default, so let's make this off-by-default for now. Maybe the `application` and `system` sections should merge?
| * Reload configuration when our configuration files change.Nick Mathewson2022-02-013-1/+69
| | | | | | | | Closes #270

| | | | | | | | | | | | | | | Earlier versions have a bug in UnboundedReceiver that make our new dirclient tests fail.

* / | Remove many needless borrows and slicesIan Jackson2022-02-021-2/+2
|/ / | | | | | | | | | | | | Found via clippy::needless_borrow. In some cases I removed needless `[..]` too. See also: needless_borrow suggestion doesn't go far enough https://github.com/rust-lang/rust-clippy/issues/8389
* | Un-Arc<> TorClient in the arti crateNick Mathewson2022-02-012-8/+5
| | | | | | | | | | TorClient doesn't need to be wrapped in an Arc any longer, thanks to other refactoring.
* | arti_config: Refactor configuration sources into a structNick Mathewson2022-02-011-19/+24
|/ | | | | | | | | | | | | | | | | | | This is by no means our final API, but should represent an improvement. Here instead of having to specify a list of files and their is-this-optional status, along with a list of command-line options, we have a single structure that encapsulates all of that information. Two advantages here: - Callers no longer have to remember what the boolean means. - We can "reload" more easily, by keeping the source object around. This change also implements the correct behavior for our default configuration file in `arti::main`: if the file is absent and the user doesn't list a config file, that's no problem. But if the user lists _that very same config file, we should insist that it be present.

* Rename `SpawnBlocking` trait to `BlockOn`.Nick Mathewson2022-01-261-1/+1
| | | | | This avoids a future confusion with the new `SpawnBlocking` trait in async_executors v0.5, and better describes what the trait provides.
* Make the native-tls crate optional.Nick Mathewson2022-01-262-3/+5
| | | | | | | | | | | This commit puts the native-tls crate behind a feature. The feature is off-by-default in the tor-rtcompat crate, but can be enabled either from arti or arti-client. There is an included script that I used to test that tor-rtcompat could build and run its tests with all subsets of its features. Closes #300
* Make current/create functions into runtime member functions.Nick Mathewson2022-01-261-3/+5
| | | | | This should help avoid some amount of temptation towards API proliferation.

* StreamPrefs: rename from ConnectPrefsIan Jackson2022-01-211-3/+3
| | | | | | | | | | | | | The docs even say this is about stream. As @nickm writes in https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/252#note_2771289 we generally call end-to-end connections that are tunneled over Tor "Streams" to distinguish them from everything else in the Tor protocols that could possibly be called a "Connection". That seems to apply here too.
* connection preferences: Take ConnectPrefs by referenceIan Jackson2022-01-191-3/+3
| | | | | This may save quite a bit of copying. The callees don't need to copy the whole struct; they copy the bits they need.

* Tracing configuration for logfiles, per-target filtersNick Mathewson2022-01-103-36/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we could only configure one global tracing filter that applied to stdout and journald. There was no support for log files, either. This patch fixes both issues, by substantially revising the configuration format: There are now separate filters for each log file, for journald, and for the console log. Because we want to allow multiple logfiles, they have to go into an array in the configuration. The configuration logic has grown a bit complicated in its types, since the tracing_subscriber crate would prefer to have the complete structure of tracing Layers known statically. That's fine when you know how many you have, and which kinds there will be, but for the runtime-configuration case we need to mess around with `Box<dyn Layer ...>`. I also had to switch from tracing_subscriber's EnvFilter to its Targets filter. It seems "EnvFilter" can only be applied as a Layer in itself, and won't work as a Filter on an individual Layer. Closes #166. Closes #170.
