This picks up moonfire-ffmpeg's 4b13378:
support ffmpeg's multi-call log messages
This should fix this annoying log output:
```
W20210310 13:17:09.060 s-garage_west-main moonfire_ffmpeg::rtsp] 0xaf300950: RTP H.264 NAL unit type 29
W20210310 13:17:09.060 s-garage_west-main moonfire_ffmpeg::rtsp] 0xaf300950: is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
```
so it looks like this instead:
```
W20210310 13:17:09.060 s-garage_west-main moonfire_ffmpeg::rtsp] 0xaf300950: RTP H.264 NAL unit type 29 is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
```
I think this has a minor behavior change: permission denied replies
change to HTTP 403 where they were HTTP 401. The new behavior seems
more correct, as these errors can occur when authentication has
succeeded but the session in question is not authorized for the given
operation. The UI currently doesn't care about this distinction.
Looks like a refactoring in 9d7cdc09 introduced the possibility this
could fail (where before it might produce a silly i32 pts) and forgot
to restore the invariant.
* add more description to the troubleshooting guide
* adjust the log format to match more recent glog
* include a config for the lnav tool, which will help colorize,
browse, and search the logs.
Next up: install an ffmpeg log callback for consistency.
Otherwise `moonfire-nvr check --delete-orphan-rows` can fail with this
error:
```
I0305 113848.655 main moonfire_db::check] Deleting 2 recording rows
E0305 113848.655 main moonfire_nvr] Exiting due to error: FOREIGN KEY constraint failed
```
The new order matches the online system's `db::raw::delete_recordings`.
It worked fine on my laptop with node.js v14.15.4, but not on my
new workstation with node.js v12.18.2 (as comes with Ubuntu 20.10).
It would print "Unexpected token '?'" without any clue what file the
error is in. I'm trying to fix that here:
https://github.com/facebook/create-react-app/pull/10652
(and various other lockfile upgrades. "npm audit" is clean.)
The date picker to use with 4.0 is unmaintained, and the new one is
apparently quite different.
Given that 5.0 is expected to be released this quarter, I prefer to
jump straight to the new one and get things working with it, even if
it means using an alpha in the short-term.
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.
This eases build setup. Where Yarn requires a separate package
repository, npm is available in the standard one.
yarn's package repository signature was recently expired, and apparently
will expire again in a year. Avoid dealing with that.
Fixes#110.
For recovering from corruption, as in #107. These should aid in
restoring database integrity without throwing away the entire database.
I only added the conditions that came up in #107, so far.
* "Missing ... row" => --trash-orphan-sample-files
* "Recording ... missing file" => --delete-orphan-rows
* "bad video_index" => --trash-corrupt-rows
In particular, if there are recordings in progress when the process
dies, they may still be around when check runs. They are easily
identifiable by having an id > cum_recordings and get automatically
deleted on startup, so there's no reason to complain about them.
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.
* give a rule of thumb for update time in the documentation
* log the SQLite3 version, which can affect performance
* do the vacuum in non-WAL mode, to correctly set the page size and to
avoid very slow behavior on older SQLite3 versions. Larger page sizes
are generally faster (including subsequent vacuum operations).
This won't help much for the first vacuum after this change, but it
will help afterward.
* likewise, set the page size properly on "moonfire-nvr init".
This was mostly straightforward. The most confusing part waas the Sync
bound change on body streams. I copied what hyper did and it seemed to
work. /shruggie
