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
Since 0.7.0, the one in the db package is used both for actual storage
within the database and for API use. I left the API-specific version
around by accident.
SelectView::set_selection doesn't seem to be working properly. The
symptom is editing an existing camera will clear the sample file dir,
and thus hitting edit without making any changes will fail.
This drops several older dependencies and reduces final binary size
(text section by ~200KiB, unstripped binary by ~12MiB)
I'll have to manually add new hash formats, and I won't ever be able
to take advantage of libpasta's (currently unused) facility to wrap
hashes, but I think it's worth it. libpasta isn't well-maintained.
- 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.
