Unreleased - xxxx-xx-xx

Added

• New StatsD metrics:
  • Counters:
    • ely.skinsystem.{hostname}.app.profiles.request

Changed

• Bumped Go version to 1.21.

Removed

• StatsD metrics:
• Gauges:
  • ely.skinsystem.{hostname}.app.redis.pool.available
• Worker mode. Use URL spoofing to load balance outgoing requests.

4.6.0 - 2021-03-04

Added

• /profile/{username} endpoint, which returns a profile and its textures, equivalent of the Mojang's UUID -> Profile + Skin/Cape endpoint.
• /signature-verification-key.der and /signature-verification-key.pem endpoints, which returns the public key in DER or PEM formats for signature verification.

Fixed

• #28: Added handling of corrupted data from the Mojang's username to UUID cache.
• #29: If a previously cached UUID no longer exists, it will be invalidated and re-requested.
• Use correct status code for error about empty response from Mojang's API.

Changed

• BREAKING: /cloaks/{username} and /textures/{username} endpoints will no longer return a cape if there are no textures for the requested username.
• All endpoints are now returns 500 status code when an error occurred during request processing.
• Increased the response timeout for Mojang's API from 3 to 10 seconds.

4.5.0 - 2020-05-01

Added

• #24: Implemented a new strategy for the queue in the batch provider of Mojang UUIDs: full-bus.
• New configuration param QUEUE_STRATEGY with the default value periodic.
• New configuration params: MOJANG_API_BASE_URL and MOJANG_SESSION_SERVER_BASE_URL, that allow you to spoof Mojang API base addresses.
• New health checker, that ensures that response for textures provider from Mojang's API is valid.
• dev Docker images now have the --cpuprofile flag, which allows you to run the program with CPU profiling.
• New StatsD metrics:
  • Gauges:
    • ely.skinsystem.{hostname}.app.redis.pool.available

Fixed

• Handle the case when there is no textures property in Mojang's response.
• Handle SIGTERM as a valid stop signal for a graceful shutdown since it's the default stop code for the Docker.
• Default connections pool size for Redis.

Changed

• ely.skinsystem.{hostname}.app.mojang_textures.usernames.round_time timer will not be recorded if the iteration was empty.

4.4.1 - 2020-04-24

Added

• #20: Print hostname in the version command output.
• #21: Print Chrly's version during server startup.

Fixed

• #22: Correct version passing during building of the Docker image.

4.4.0 - 2020-04-22

Added

• Mojang textures queue now can be completely disabled via MOJANG_TEXTURES_ENABLED param.

• Remote mode for Mojang's textures queue with a new configuration params: MOJANG_TEXTURES_UUIDS_PROVIDER_DRIVER and MOJANG_TEXTURES_UUIDS_PROVIDER_URL.

  For example, to send requests directly to Mojang's APIs, set the next configuration:

  • MOJANG_TEXTURES_UUIDS_PROVIDER_DRIVER=remote
  • MOJANG_TEXTURES_UUIDS_PROVIDER_URL=https://api.mojang.com/users/profiles/minecraft/

• Implemented worker mode. The app starts with the only one API endpoint: /api/worker/mojang-uuid/{username}, which is compatible with Mojang's endpoint to exchange username to its UUID. It can be used with some load balancing software to increase throughput of Mojang's textures proxy by splitting the load across multiple servers with its own IPs.

• Textures extra param is now can be configured via TEXTURES_EXTRA_PARAM_NAME and TEXTURES_EXTRA_PARAM_VALUE.

• New StatsD metrics:

  • Counters:
    • ely.skinsystem.{hostname}.app.mojang_textures.usernames.textures_hit
    • ely.skinsystem.{hostname}.app.mojang_textures.usernames.textures_miss

• All incoming requests are now logging to the console in Apache Common Log Format.

• Added /healthcheck endpoint.

• Graceful server shutdown.

• Panics in http are now logged in Sentry.

Fixed

• ely.skinsystem.{hostname}.app.mojang_textures.usernames.iteration_size and ely.skinsystem.{hostname}.app.mojang_textures.usernames.queue_size are now updates even if the queue is empty.
• Don't return an empty object if Mojang's textures don't contain any skin or cape.
• Provides a correct URL scheme for the cape link.

Changed

• BREAKING: QUEUE_LOOP_DELAY param is now sets as a Go duration, not milliseconds. For example, default value is now 2s500ms.
• BREAKING: Event ely.skinsystem.{hostname}.app.mojang_textures.already_in_queue has been renamed into ely.skinsystem.{hostname}.app.mojang_textures.already_scheduled.
• Bumped Go version to 1.14.

Removed

• BREAKING: ely.skinsystem.{hostname}.app.mojang_textures.invalid_username counter has been removed.

Changed

• Bumped Go version to 1.12.

Fixed

• /textures request no longer proxies request to Mojang in a case when there is no information about the skin, but there is a cape.

Removed

• hash field from /textures response because the game doesn't use it and calculates hash by getting the filename from the textures link instead.
• hash field from POST /api/skins endpoint.
