Bump version to 4.6.0-test.3

Remove env variables from example config.
Initially this was added to make development using Docker Compose easier. However, in my experience Docker Compose is not great for the reason that there might be environmental differences between Rust running in Compose and Rust running outside Compose (if using VSCode with Rust plugin, then rust-analyzer will perform checks in the background). This and 'cross' not working properly in Compose was the reason to migrate to nix, as it provides a reproducible environment for development that can also be used by VSCode (using the Nix environment selector extension) and GitHub Actions (for the CI pipeline). As the chirpstack-docker repository provides its own configuration files, these files are not included in the Dockerfile and because we are rewriting these env variables anyway to 'localhost' in the .deb and .rpm post-installation script, it is better to set these to localhost by default. The post-installation rewrite to 'localhost' is causing issues on upgrade (#295). If we only do the rewrite on initial installation, then we run in an other issue; the package-manager will prompt that the config file has changed (from 'localhost' to '$MQTT_BROKER_HOST' for example) and will ask if you would like to overwrite or not. If the end-user would accept the config changes without looking at the diff this would break the installation as most likely, these environment are not set (which is why we were rewriting these to 'localhost' in the first place).

Author	SHA1	Message	Date
Orne Brocaar	f13a5f492c	Bump version to 4.6.0-test.3	2023-11-22 11:28:00 +00:00
Orne Brocaar	c0cd3a3361	Remove env variables from example config. Initially this was added to make development using Docker Compose easier. However, in my experience Docker Compose is not great for the reason that there might be environmental differences between Rust running in Compose and Rust running outside Compose (if using VSCode with Rust plugin, then rust-analyzer will perform checks in the background). This and 'cross' not working properly in Compose was the reason to migrate to nix, as it provides a reproducible environment for development that can also be used by VSCode (using the Nix environment selector extension) and GitHub Actions (for the CI pipeline). As the chirpstack-docker repository provides its own configuration files, these files are not included in the Dockerfile and because we are rewriting these env variables anyway to 'localhost' in the .deb and .rpm post-installation script, it is better to set these to localhost by default. The post-installation rewrite to 'localhost' is causing issues on upgrade (#295). If we only do the rewrite on initial installation, then we run in an other issue; the package-manager will prompt that the config file has changed (from 'localhost' to '$MQTT_BROKER_HOST' for example) and will ask if you would like to overwrite or not. If the end-user would accept the config changes without looking at the diff this would break the installation as most likely, these environment are not set (which is why we were rewriting these to 'localhost' in the first place).	2023-11-22 11:10:13 +00:00

Orne Brocaar	f81b868a31	ui: Reload device on change event. Fixes #319.	2023-11-13 14:17:45 +00:00
Orne Brocaar	464937169b	ui: Make device metric name optional. If enabled, metrics will be automatically detected and created based on the decoded payload. The key will be set, but the name is left blank for the user to configure. This can be confusing as it leads to validation errors in the device-profile form if the name is not filled in. The UI does show that one of the fields failed to validate, but even with such notification, it is not clear that users have to check one of the form tabs which they didn't edit on save. This makes the name optional and uses the key as fallback such that saving the form no longer fails in case the name is still blank. Closes #313.	2023-11-10 16:50:17 +00:00
