- after 3->4 upgrade, it left the foreign key referring to the
nonexistent old_camera table. Likely no one who did the upgrade
has ever inserted anything into this table, so no one's noticed.
- 6->7 upgrade dropped tables in the wrong order, so if there was
anything in the signal_camera table, the upgrade would fail.
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.
Before it would produce this incorrect message that told you to run
the command you just ran:
```
$ nvr init --db-dir=/nonexistent/db
E20211021 09:08:23.798 main moonfire_nvr] Exiting due to error: db dir /nonexistent/db not found; try running moonfire-nvr init
caused by: ENOENT: No such file or directory
```
Now the same command produces the following:
```
$ nvr init --db-dir=/nonexistent/db
E20211021 09:09:11.056 main moonfire_nvr] Exiting due to error: unable to create db dir /nonexistent/db
caused by: ENOENT: No such file or directory
```
Add tests just for good measure.
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.
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.
* upgrade to Retina 0.3.1 which automatically tears down sessions
* wait out stale sessions before reconnecting
* wait for teardown to complete before shutting down
This adds some pressure on #117: it will keep waiting for the stale
session to expire even if the user has requested shutdown. I'll try
to address that next.
I copied the example of the password field by introducing a setter.
But I forgot: it was only that way because the password field has
the complexity of hashing/salting. For fields where setting is
idempotent, it can be directly exposed.
This mostly affects .mp4 init segments (#146), which currently set the
Last-Modified: date to the epoch. It could also affect other resources
(static files, other .mp4 changes) but only if the clock has gone
backwards.
I forgot to do this in 27395ec resulting in #146. Bump the version now,
and update the digest used in the tests so they will remind me to
bump the version any time the headers change.
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.
Fixes#136

For #136. I'm also going to make this particular case no longer panic,
but there will surely be other affected panics.
