Raw Normal View History

tests and fixes for Writer and Syncer * separate these out into a new file, writer.rs, as dir.rs was getting unwieldy. * extract traits for the parts of SampleFileDir and std::fs::File they needed; set up mock implementations. * move clock.rs to a new base crate to be accessible from the db crate. * add tests that exercise all the retry paths. * bugfix: account for the new recording's bytes when calculating how much to delete. * bugfix: when retrying an unlink failure in collect_garbage, we shouldn't warn about all the recordings no longer existing. Do this by retrying each step rather than the whole procedure again. * avoid double-panic scenarios, which I hit while tweaking the mocks. These are quite annoying to debug as Rust doesn't print information about either panic. I ended up using lldb to get a backtrace. Better to be cautious about what we're doing when already panicking. * give more context on raw::insert_recording errors, which I hit as well while tweaking the new tests.

upgrade to 2018 Rust edition This is mostly just "cargo fix --edition" + Cargo.toml changes. There's one fix for upgrading to NLL in db/writer.rs: Writer::previously_opened wouldn't build with NLL because of a double-borrow the previous borrow checker somehow didn't catch. Restructure to avoid it. I'll put elective NLL changes in a following commit.

shorten per-file copyright headers I'm tired of all the boilerplate, so use the new GPL-3.0-linking-exception license identifier instead in all the server components. I left the ui stuff alone because I'm just going to replace it (#111). Add a checker for the header because it's easy to forget.

shutdown better After a frustrating search for a suitable channel to use for shutdown (tokio::sync::watch::Receiver and futures::future::Shared<tokio::sync::oneshot::Receiver> didn't look quite right) in which I rethought my life decisions, I finally just made my own (server/base/shutdown.rs). We can easily poll it or wait for it in async or sync contexts. Most importantly, it's convenient; not that it really matters here, but it's also efficient. We now do a slightly better job of propagating a "graceful" shutdown signal, and this channel will give us tools to improve it over time. * Shut down even when writer or syncer operations are stuck. Fixes #117 * Not done yet: streamers should instantly shut down without waiting for a connection attempt or frame or something. I'll probably implement that when removing --rtsp-library=ffmpeg. The code should be cleaner then. * Not done yet: fix a couple places that sleep for up to a second when they could shut down immediately. I just need to do the plumbing for mock clocks to work. I also implemented an immediate shutdown mode, activated by a second signal. I think this will mitigate the streamer wait situation.

better logs during normal operation * don't log every time we delete stuff; leave it for the flush * when flushing, break apart counts by sample file dir and include human-readable sizes

refine timestamps in json signals api * API change: in update signals, allow setting a start time relative to now. This is an accuracy improvement in the case where the client has been retrying an initial request for a while. Kind of an obscure corner case but easy enough to address. And use a more convenient enum representation. * in update signals, choose `now` before acquiring the database lock. If lock acquisition takes a long time, this more accurately reflects the time the caller intended. * in general, make Time and Duration (de)serializable and use them in json types. This makes the types more self-describing, with better debug printing on both the server side and on the client library (in moonfire-playground). To make this work, base has to import serde which initially seemed like poor layering to me, but serde seems to be imported in some pretty foundational Rust crates for this reason. I'll go with it.
