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.
Now you can set a password for a user while the server is running,
e.g. via the following command:
```shell
curl \
-H 'Content-Type: application/json' \
-d '{"update": {"password": "asdf"}}' \
--unix-socket /var/lib/moonfire-nvr/sock \
http://nvr/api/users/1
```
Symptom: in `nvr config`, if you create a dir and then immediately try
to delete it, it would fail saying it's in-use. This check is supposed
to be for having a running syncer on the directory, which would be
an arc count > 1.
This stops using parking_lot entirely. Since Rust 1.62, the std
implementations on Linux are direct futexes, not the boxed pthread
mutexes they used to be. No real reason to use parking_lot anymore, so
shed this dependency.
This is better particularly when the user is following the docker
instructions and doesn't have a local checkout at all. It also is a
rendered HTML view rather than raw markdown.
It'd be nice to link to the exact release we're using, not tip of
master. I didn't do this now because it'll likely take some work with
build.rs to check if the user is on a tagged release or not.
Fixes#180
Now there's room to add arbitrary configuration to signals and types.
Several things are no longer fixed columns/tables but instead within
the configuration types.
This fixes#178. Before, everything got translated to 5xx status;
now it produces the correct type in several cases.
Ideally I'd get rid of the untyped errors in all of web.rs; this is
a small step.
I saw this recently while working on new-schema. It was probably due
to some manual upgrade or downgrade I did rather than an actual bug.
Improve debuggability a little nonetheless.
As written in the changelog: Live streams formerly worked around a
Firefox pixel aspect ratio bug by forcing all videos to 16:9, which
dramatically distorted 9:16 camera views. Playback didn't, so anamorphic
videos looked correct on Chrome but slightly stretched on Firefox. Now
both live streams and playback are fully correct on all browsers.
This isn't well-tested and doesn't yet support an initial connection
timeout. But in a quick test, it successfully returns video!
I'd like to do some more aggressive code restructuring for zero-copy
and to have only one writer thread per sample file directory (rather
than the syncer thread + one writer thread per RTSP stream). But I'll
likely wait until I drop support for ffmpeg entirely.
I saw this error once:
Apr 27 21:01:33 nuc moonfire-nvr[188570]: s-reolink-sub
moonfire_nvr::streamer] reolink-sub: sleeping for Duration { secs: 1,
nanos: 0 } after error: CHECK constraint failed: video_sample_entry
and would like to understand it better.
I spotted this by inspection: adding a media time and wall time didn't
look right. I also confirmed the brokenness on my primary NVR:
```

```
In the first row, the second recording's prev_media_duration_90k is the
first's prev_media_duration_90k plus its wall time, not its media time.
My main goal is to support creating indexes for signals as well as
recordings. An additional goal is to just shrink db.rs a bit; it's
gotten quite large.
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.
