pict-rs 0.5.13

pict-rs is a simple image hosting microservice, designed to handle storing and retrieving images, animations, and videos, as well as providing basic image processing functionality.

Overview

pict-rs 0.5.13 is a maintenance release aiming to enable better logging in some scenarios.

Features

• Colorless Logging

Changes

• Remove Flume

Upgrade Notes

There are no significant changes from 0.5.12. Upgrading should be as simple as pulling a new version of pict-rs.

Descriptions

Colorless Logging

When opting to use the json logger, the tracing subscriber automatically disables colored output. This didn't remove colors from errors, though, and pict-rs hasn't had a way to disable colors while using other log formats. pict-rs 0.5.13 introduces a new configuration value to remove colored output from all logs regardless of logging format.

With pict-rs.toml

[tracing.logging]
no_ansi = true

With environment variables

PICTRS__TRACING__LOGGING__NO_ANSI=true pict-rs run

With commandline flags

pict-rs --no-log-ansi run

Colors in logs can be useful, so I imagine this option won't be used much. There has been a request for this functionality though and it's little cost to maintain.

Remove Flume

Recently I've been debugging a memory usage issue in another project of mine. I wasn't able to fully track down the cause, but I did notice that removing the flume channel library seemed to make the leak go away. Since I also use flume in pict-rs, I'm opting to replace it with tokio's native channel implementation. This may or may not improve memory usage, but it does reduce the depenency count and therefore build time for pict-rs.
