This is a step toward H.265 recording support (#33) by using Retina
for the `VisualSampleEncoding` instead of the prior H.264-specific
logic. The only further change to Moonfire itself needed for H.265 is to
add `| "h265"` to the check for the right video stream.
This also adds support for recording MJPEG, although browser playback
almost certainly won't work.
* use `termion` rather than `ncurses` to limit runtime deps
* cross-compile with `cross` instead of our own dockerfiles/scripts
* update instructions
* update release procedure and GitHub actions to match
* prep changelog for `v0.7.8`
Fixes#160Closes#265
This is optional but now enabled for release builds.
Why?
* It shrinks the release docker images a bit, as the binary
includes only the gzipped version of files and uncompressed into RAM
at startup (which should be fast).
* It's a step toward #160.
Sessions' last use updates weren't getting persisted to the database
because the update statement wasn't passing through the hash.
Also address a TODO of tracing in tests by using the same tracing
setup as in production.
I think this is a big improvement in readability.
I removed the `lnav` config, which is a little sad, but I don't think it
supports this structured logging format well. Still seems worthwhile on
balance.
* take advantage of new features to default to `--help` and to print
the defaults
* remove blank lines from argument help docstrings to avoid truncating
the output on single `--help` arg (as opposed to `--help --help`)
I'd use the actual released 0.9.1 but it looks like it's not quite out
yet. Will switch over when it is.
Improves #70: this reduces binary size from 12.3 MiB to 11.9 MiB (3%) on
macOS/arm64.
The user experience is almost the same. (The help output's `Usage:`
lines lack the e.g. `moonfire-nvr run` prefix of argv[0] and subcommand,
which isn't ideal, but I guess it's pretty minor in the grand scheme of
things.)
After a frustrating search for a suitable channel to use for shutdown
(tokio::sync:⌚: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.
For #136. I'm also going to make this particular case no longer panic,
but there will surely be other affected panics.
Before:
```
E20210803 08:58:31.606 main moonfire_nvr] panic at '/Users/slamb/.cargo/registry/src/github.com-1ecc6299db9ec823/hyper-0.14.10/src/server/server.rs:68:17'
```
After:
```
E20210803 08:59:51.319 main moonfire_nvr] panic at '/Users/slamb/.cargo/registry/src/github.com-1ecc6299db9ec823/hyper-0.14.10/src/server/server.rs:68:17': error binding to 0.0.0.0:80: error creating server listener: Address already in use (os error 48)
```
This is (slightly) complicating the switch from ffmpeg to retina
as the RTSP client. And it's not really that close to what I want
to end up with for analytics:
* I'd prefer the analytics happen in a separate process for
several reasons
* Feeding the entire frame to the object detector doesn't produce
good results.
* It doesn't do anything with the results yet anyway.
In particular, this was happening out of the box on Raspberry Pi OS Lite
20210304, as reported by ironoxidizer@gmail.com here:
https://groups.google.com/g/moonfire-nvr-users/c/2j9LvfFl2u8/m/tJcNS2WfCQAJ
* adjust main.rs to make the problem more obvious
* mention it in the troubleshooting guide
* sidestep it in the nvr docker wrapper script
also just use --networking=host rather than --publish (avoiding a proxy
process). I'm using Docker to simplify the build and deployment process,
not as a security boundary, so just do the simpler thing.
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.
I want to make the project more accessible by not expecting folks to
match my idiosyncratic style. Now almost [1] everything is written
in the "standard" style. CI enforces this.
[1] "Almost": I used #[rustfmt::skip] in a few sections where I felt
aligning things in columns significantly improves readability.
Inspired by the poor error message here:
https://github.com/scottlamb/moonfire-nvr/issues/107#issuecomment-777587727
* print the friendlier Display version of the error rather than Debug.
Eg, "EROFS: Read-only filesystem" rather than "Sys(EROFS)". Do this
everywhere: on command exit, on syncer retries, and on stream
retries.
* print the most immediate problem and additional lines for each
cause.
* print the backtrace or an advertisement for RUST_BACKTRACE=1 if it's
unavailable.
* also mention RUST_BACKTRACE=1 in the troubleshooting guide.
* add context in various places, including pathnames. There are surely
many places more it'd be helpful, but this is a start.
* allow subcommands to return failure without an Error.
In particular, "moonfire-nvr check" does its own error printing
because it wants to print all the errors it finds. Printing "see
earlier errors" with a meaningless stack trace seems like it'd just
confuse. But I also want to get rid of the misleading "Success" at
the end and 0 return to the OS.
Besides being more clear about what belongs to which, this helps with
docker caching. The server and ui parts are only rebuilt when their
respective subdirectories change.
Extend this a bit further by making the webpack build not depend on
the target architecture. And adding cache dirs so parts of the server
and ui build process can be reused when layer-wide caching fails.
