Rust rewrite I should have submitted/pushed more incrementally but just played with it on my computer as I was learning the language. The new Rust version more or less matches the functionality of the current C++ version, although there are many caveats listed below. Upgrade notes: when moving from the C++ version, I recommend dropping and recreating the "recording_cover" index in SQLite3 to pick up the addition of the "video_sync_samples" column: $ sudo systemctl stop moonfire-nvr $ sudo -u moonfire-nvr sqlite3 /var/lib/moonfire-nvr/db/db sqlite> drop index recording_cover; sqlite3> create index ...rest of command as in schema.sql...; sqlite3> ^D Some known visible differences from the C++ version: * .mp4 generation queries SQLite3 differently. Before it would just get all video indexes in a single query. Now it leads with a query that should be satisfiable by the covering index (assuming the index has been recreated as noted above), then queries individual recording's indexes as needed to fill a LRU cache. I believe this is roughly similar speed for the initial hit (which generates the moov part of the file) and significantly faster when seeking. I would have done it a while ago with the C++ version but didn't want to track down a lru cache library. It was easier to find with Rust. * On startup, the Rust version cleans up old reserved files. This is as in the design; the C++ version was just missing this code. * The .html recording list output is a little different. It's in ascending order, with the most current segment shorten than an hour rather than the oldest. This is less ergonomic, but it was easy. I could fix it or just wait to obsolete it with some fancier JavaScript UI. * commandline argument parsing and logging have changed formats due to different underlying libraries. * The JSON output isn't quite right (matching the spec / C++ implementation) yet. Additional caveats: * I haven't done any proof-reading of prep.sh + install instructions. * There's a lot of code quality work to do: adding (back) comments and test coverage, developing a good Rust style. * The ffmpeg foreign function interface is particularly sketchy. I'd eventually like to switch to something based on autogenerated bindings. I'd also like to use pure Rust code where practical, but once I do on-NVR motion detection I'll need to existing C/C++ libraries for speed (H.264 decoding + OpenCL-based analysis).

upgrade to async hyper serve_generated_bytes is >3X faster. One caveat is that the reactor thread may stall when reading from the memory-mapped slice. Moonfire NVR is basically a single-user program, so that may not be so bad, but we'll see.

# The nightly feature is used within moonfire-nvr itself to gate the
# benchmarks. Also pass it along to crates that can benefit from it.
fix #64 (extraneous flushes) Now each syncer has a binary heap of the times it plans to do a flush. When one of those times arrives, it rechecks if there's something to do. Seems more straightforward than rechecking each stream's first uncommitted recording, especially with the logic to retry failed flushes every minute. Also improved the info! log for each flush to see the actual recordings being flushed for better debuggability. No new tests right now. :-( They're tricky to write. One problem is that it's hard to get the timing right: a different flush has to happen after Syncer::save's database operations and before Syncer::run calls SimulatedClocks::recv_timeout with an empty channel[*], advancing the time. I've thought of a few ways of doing this: * adding a new SyncerCommand to run something, but it's messy (have to add it from the mock of one of the actions done by the save), and Box<dyn FnOnce() + 'static> not working (see rust-lang/rust#28796) makes it especially annoying. * replacing SimulatedClocks with something more like MockClocks. Lots of boilerplate. Maybe I need to find a good general-purpose Rust mock library. (mockers sounds good but I want something that works on stable Rust.) * bypassing the Syncer::run loop, instead manually running iterations from the test. Maybe the last way is the best for now. I'm likely to try it soon. [*] actually, it's calling Receiver::recv_timeout directly; Clocks::recv_timeout is dead code now? oops.

upgrade rusqlite and support bundled library SQLite3 has gotten some noticeable speed improvements in recent releases. This is a modest improvement on reasonably new platforms, and a pretty significant one on Raspbian Jessie (which has an incredibly old SQLite3).

initial split of database to a separate crate It should reduce compile time / memory usage to put quite a bit of the code into a separate crate. I also intend to limit visibility of some things to only within the db crate, but that's for a future change. This is the smallest move that will compile.

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.

add a basic Javascript UI The Javascript is pretty amateurish I'm sure but at least it's something to iterate from. It's already much more pleasant for browsing through videos in several ways: * more responsive to load only a day at a time rather than 90+ days * much easier to see the same time segment on several cameras * more pleasant to have the videos load as a popup rather than a link that blows away your position in an enormous list * exposes the fancier .mp4 generation options: splitting at lengths other than the default, trimming to an arbitrary start and end time, including a subtitle track with timestamps. There's a slight regression in functionality: I didn't match the former top-level page which showed how much camera used of its disk allocation and the total duration of video. This is exposed in the JSON API, so it shouldn't be too hard to add back.

preliminary web support for auth (#26) Some caveats: * it doesn't record the peer IP yet, which makes it harder to verify sessions are valid. This is a little annoying to do in hyper now (see hyperium/hyper#1410). The direct peer might not be what we want right now anyway because there's no TLS support yet (see #27). In the meantime, the sane way to expose Moonfire NVR to the Internet is via a proxy server, and recording the proxy's IP is not useful. Maybe better to interpret a RFC 7239 Forwarded header (and/or the older X-Forwarded-{For,Proto} headers). * it doesn't ever use Secure (https-only) cookies, for a similar reason. It's not safe to use even with a tls proxy until this is fixed. * there's no "moonfire-nvr config" support for inspecting/invalidating sessions yet. * in debug builds, logging in is crazy slow. See libpasta/libpasta#9. Some notes: * I removed the Javascript "no-use-before-defined" lint, as some of the functions form a cycle. * Fixed #20 along the way. I needed to add support for properly returning non-OK HTTP statuses to signal unauthorized and such. * I removed the Access-Control-Allow-Origin header support, which was at odds with the "SameSite=lax" in the cookie header. The "yarn start" method for running a local proxy server accomplishes the same thing as the Access-Control-Allow-Origin support in a more secure manner.

add concept of user/session permissions (I also considered the names "capabilities" and "scopes", but I think "permissions" is the most widely understood.) This is increasingly necessary as the web API becomes more capable. Among other things, it allows: * non-administrator users who can view but not access camera passwords or change any state * workers that update signal state based on cameras' built-in motion detection or a security system's events but don't need to view videos * control over what can be done without authenticating Currently session permissions are just copied from user permissions, but you can also imagine admin sessions vs not, as a checkbox when signing in. This would match the standard Unix workflow of using a non-administrative session most of the time. Relevant to my current signals work (#28) and to the addition of an administrative API (#35, including #66).

uuid = { version = "0.7", features = ["serde", "std", "v4"] }
fully implement json handling as in spec This is a significant milestone; now the Rust branch matches the C++ branch's features. In the process, I switched from using serde_derive (which requires nightly Rust) to serde_codegen (which does not). It was easier than I thought it'd be. I'm getting close to no longer requiring nightly Rust.

Rust rewrite I should have submitted/pushed more incrementally but just played with it on my computer as I was learning the language. The new Rust version more or less matches the functionality of the current C++ version, although there are many caveats listed below. Upgrade notes: when moving from the C++ version, I recommend dropping and recreating the "recording_cover" index in SQLite3 to pick up the addition of the "video_sync_samples" column: $ sudo systemctl stop moonfire-nvr $ sudo -u moonfire-nvr sqlite3 /var/lib/moonfire-nvr/db/db sqlite> drop index recording_cover; sqlite3> create index ...rest of command as in schema.sql...; sqlite3> ^D Some known visible differences from the C++ version: * .mp4 generation queries SQLite3 differently. Before it would just get all video indexes in a single query. Now it leads with a query that should be satisfiable by the covering index (assuming the index has been recreated as noted above), then queries individual recording's indexes as needed to fill a LRU cache. I believe this is roughly similar speed for the initial hit (which generates the moov part of the file) and significantly faster when seeking. I would have done it a while ago with the C++ version but didn't want to track down a lru cache library. It was easier to find with Rust. * On startup, the Rust version cleans up old reserved files. This is as in the design; the C++ version was just missing this code. * The .html recording list output is a little different. It's in ascending order, with the most current segment shorten than an hour rather than the oldest. This is less ergonomic, but it was easy. I could fix it or just wait to obsolete it with some fancier JavaScript UI. * commandline argument parsing and logging have changed formats due to different underlying libraries. * The JSON output isn't quite right (matching the spec / C++ implementation) yet. Additional caveats: * I haven't done any proof-reading of prep.sh + install instructions. * There's a lot of code quality work to do: adding (back) comments and test coverage, developing a good Rust style. * The ffmpeg foreign function interface is particularly sketchy. I'd eventually like to switch to something based on autogenerated bindings. I'd also like to use pure Rust code where practical, but once I do on-NVR motion detection I'll need to existing C/C++ libraries for speed (H.264 decoding + OpenCL-based analysis).

[dev-dependencies]
update most deps, notably including reqwest Fixes #60 The reqwest dependency is significant because the old version required an old version of openssl, complicating compilation on newer platforms. reqwest also pulled in old/duplicate versions of hyper, tokio, etc. Nice to drop a lot of that cruft. I left rusqlite and uuid alone because they had breaking changes I didn't want to mess with at the moment. Bumped the minimum Rust version to 1.30.0, as required by the new encoding_rs crate (and perhaps other things).
