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.
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.

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).

[workspace]
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.

futures = "0.1"
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.

use my own ffmpeg crate This significantly improves safety of the ffmpeg interface. The complex ABIs aren't accessed directly from Rust. Instead, I have a small C wrapper which uses the ffmpeg C API and the C headers at compile-time to determine the proper ABI in the same way any C program using ffmpeg would, so that the ABI doesn't have to be duplicated in Rust code. I've tested with ffmpeg 2.x and ffmpeg 3.x; it seems to work properly with both where before ffmpeg 3.x caused segfaults. It still depends on ABI compatibility between the compiled and running versions. C programs need this, too, and normal shared library versioning practices provide this guarantee. But log both versions on startup for diagnosing problems with this. Fixes #7

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).
