* Updated Go dependencies
### Fixed
* [CVE-2024-27102](https://www.cve.org/CVERecord?id=CVE-2024-27102)
## v1.11.8
### Changed

## v1.11.7
### Changed
* Updated Go dependencies (this resolves an issue related to `http: invalid Host header` with Docker)
* Wings is now built with go1.19.11
## v1.11.6
### Fixed
* CVE-2023-32080
## v1.11.5
### Added
* Added a config option to disable Wings config.yml updates from the Panel (https://github.com/pterodactyl/wings/commit/ec6d6d83ea3eb14995c24f001233e85b37ffb87b)
### Changed
* Wings is now built with Go 1.19.7
### Fixed
* Fixed archives containing partially matched file names (https://github.com/pterodactyl/wings/commit/43b3496f0001cec231c80af1f9a9b3417d04e8d4)
## v1.11.4
### Fixed
* CVE-2023-25168
## v1.11.3
### Fixed
* CVE-2023-25152
## v1.11.2
### Fixed
* Backups being restored from remote storage (s3) erroring out due to a closed stream.
* Fix IP validation logic for activity logs filtering out valid IPs instead of invalid IPs
## v1.11.1
### Changed
* Release binaries are now built with Go 1.18.10
* Timeout when stopping a server before a transfer begins has been reduced to 15 seconds from 1 minute
* Removed insecure SSH protocols for use with the SFTP server
### Fixed
* Unnecessary Docker client connections being left open, causing a slow leak of file descriptors
* Files being left open in parts of the server's filesystem, causing a leak of file descriptors
* IPv6 addresses being corrupted by flawed port stripping logic for activity logs, old entries with malformed IPs will be deleted from the local SQLite database automatically
* A server that times out while being stopped at the beginning of a transfer no longer causes the server to become stuck in a transferring state
## v1.11.0
### Added (since 1.7.2)
* More detailed information returned by the `/api/system` endpoint when using the `?v=2` query parameter.
### Changed (since 1.7.2)
* Send re-installation status separately from installation status.
* Wings release versions will now follow the major and minor version of the Panel.
* Transfers no longer buffer to disk, instead they are fully streamed with only a small amount of memory used for buffering.
* Release binaries are no longer compressed with UPX.
* Use `POST` instead of `GET` for sending the status of a transfer to the Panel.
### Fixed (since 1.7.2)
* Fixed servers outgoing IP not being updated whenever a server's primary allocation is changed when using the Force Outgoing IP option.
* Fixed servers being terminated rather than gracefully stopped when a signal is used to stop the container rather than a command.
* Fixed file not found errors being treated as an internal error, they are now treated as a 404.
* Wings can be run with Podman instead of Docker, this is still experimental and not recommended for production use.
* Archive progress is now reported correctly.
* Labels for containers can now be set by the Panel.
* Fixed servers becoming deadlocked when the target node of a transfer goes offline.
## v1.11.0-rc.2
### Added
* More detailed information returned by the `/api/system` endpoint when using the `?v=2` query parameter.
### Changed
* Send reinstallation status separately from installation status.
### Fixed
* Fixed servers outgoing IP not being updated whenever a server's primary allocation is changed when using the Force Outgoing IP option.
* Fixed servers being terminated rather than gracefully stopped when a signal is used to stop the container rather than a command.
* Fixed file not found errors being treated as an internal error, they are now treated as a 404.
## v1.11.0-rc.1
### Changed
* Wings release versions will now follow the major and minor version of the panel.
* Transfers no longer buffer to disk, instead they are fully streamed with only a small amount of memory used for buffering.
* Release binaries are no longer compressed with UPX.
### Fixed
* Wings can be run with podman instead of Docker, this is still experimental and not recommended for production use.
* Archive progress is now reported correctly.
* Labels for containers can now be set by the Panel.
## v1.7.5
### Fixed
* CVE-2023-32080
## v1.7.4
### Fixed
* CVE-2023-25168
## v1.7.3
### Fixed
* CVE-2023-25152
## v1.7.2
### Fixed
* The S3 backup driver now supports Cloudflare R2
### Added
* During a server transfer, there is a new "Archiving" status that outputs the progress of creating the server transfer archive.
* Adds a configuration option to control the list of trusted proxies that can be used to determine the client IP address.
* Adds a configuration option to control the Docker username space setting when Wings creates containers.
### Changed
* Releases are now built using `Go 1.18` — the minimum version required to build Wings is now `Go 1.18`.
## v1.7.1
### Fixed
* YAML parser has been updated to fix some strange issues
### Added
* Added `Force Outgoing IP` option for servers to ensure outgoing traffic uses the server's IP address
* Adds an option to control the level of gzip compression for backups
## v1.7.0
### Fixed
* Fixes multi-platform support for Wings' Docker image.
### Added
* Adds support for tracking of SFTP actions, power actions, server commands, and file uploads by utilizing a local SQLite database and processing events before sending them to the Panel.
* Adds support for configuring the MTU on the `pterodactyl0` network.
## v1.6.4
### Fixed
* Fixes a bug causing CPU limiting to not be properly applied to servers.
* Fixes a bug causing zip archives to decompress without taking into account nested folder structures.
## v1.6.3
### Fixed
* Fixes SFTP authentication failing for administrative users due to a permissions adjustment on the Panel.
## v1.6.2
### Fixed
* Fixes file upload size not being properly enforced.
* Fixes a bug that prevented listing a directory when it contained a named pipe. Also added a check to prevent attempting to read a named pipe directly.
* Fixes a bug with the archiver logic that would include folders that had the same name prefix. (for example, requesting only `map` would also include `map2` and `map3`)
* Requests to the Panel that return a client error (4xx response code) no longer trigger an exponential backoff, they immediately stop the request.
### Changed
* CPU limit fields are only set on the Docker container if they have been specified for the server — otherwise they are left empty.
### Added
* Added the ability to define the location of the temporary folder used by Wings — defaults to `/tmp/pterodactyl`.
* Adds the ability to authenticate for SFTP using public keys (requires `Panel@1.8.0`).
## v1.6.1
### Fixed
* Fixes error that would sometimes occur when starting a server that would cause the temporary power action lock to never be released due to a blocked channel.
* Fixes a bug causing the CPU usage of Wings to get stuck at 100% when a server is deleted while the installation process is running.
### Changed
* Cleans up a lot of the logic for handling events between the server and environment process to make it easier to make modifications to down the road.
* Cleans up logic handling the `StopAndWait` logic for stopping a server gracefully before terminating the process if it does not respond.
## v1.6.0
### Fixed
* Internal logic for processing a server start event has been adjusted to attach to the Docker container before attempting to start the container. This should fix issues where a server would get stuck after pulling the container image.
* Fixes a bug in the console output that was dropping console lines when a large number of lines were sent at once.
### Changed
* Removed the console throttle logic that would terminate a server instance that was sending too much data. This logic has been replaced with simpler logic that only throttles the console, it does not try to terminate the server. In addition, this change has reduced the number of go-routines needed by the application and dramatically simplified internal logic.
* Removed the `--profiler` flag and replaced it with `--pprof` which will start an internal server listening on `localhost:6060` allowing you to use Go's standard `pprof` tooling.
* Replaced the `json` log driver for Docker containers with `local` to reduce the amount of overhead when it comes to streaming logs from instances.
## v1.5.6
### Fixed
* Rewrote handler logic for the power actions lock to hopefully address issues people have been having when a server crashes and they're unable to start it again until restarting Wings.
* Fixes files uploaded with SFTP not being owned by the Pterodactyl user.
* Fixes excessive memory usage when large lines are sent through the console event handler.
### Changed
* Replaced usage of `encoding/json` throughout the codebase with a more performant encoder (`goccy/go-json`) to hopefully improve overall performance for JSON operations.
* Added custom `ContainerInspect` function to handle direct calls to Docker's CLI and make use of the new JSON encoder logic. This should reduce the total number of memory allocations and be more performant overall in a hot pathway.
## v1.5.5 ## v1.5.5
### Fixed ### Fixed
* Fixes sending to a closed channel when sending server logs over the websocket * Fixes sending to a closed channel when sending server logs over the websocket

//
// The d argument is the [DirEntry] for the named path.
//
// The error result returned by the function controls how [WalkDir]

// skips the current directory (path if d.IsDir() is true, otherwise
// path's parent directory). If the function returns the special value
// [SkipAll], WalkDir skips all remaining files and directories. Otherwise,

// calls the function with path set to root, d set to nil, and err set to

// Second, if a directory's ReadDir method (see [ReadDirFile]) fails, WalkDir calls the
// function with path set to the directory's path, d set to an
// [DirEntry] describing the directory, and err set to the error from
// ReadDir. In this second case, the function is called twice with the
// path of the directory: the first call is before the directory read is
// attempted and has err set to nil, giving the function a chance to
// return [SkipDir] or [SkipAll] and avoid the ReadDir entirely. The second call
// is after a failed ReadDir and reports the error from ReadDir.

Release: 1%{?dist}
Summary: The server control plane for Pterodactyl Panel. Written from the ground-up with security, speed, and stability in mind.

%description
Wings is Pterodactyl's server control plane, built for the rapidly
changing gaming industry and designed to be highly performant and
secure. Wings provides an HTTP API allowing you to interface directly
with running server instances, fetch server logs, generate backups,
and control all aspects of the server lifecycle.
In addition, Wings ships with a built-in SFTP server allowing your
system to remain free of Pterodactyl specific dependencies, and
allowing users to authenticate with the same credentials they would
normally use to access the Panel.

* Wed Oct 27 2021 Capitol Hosting Solutions Systems Engineering <syseng@chs.gg> - 1.5.3-1
- specfile by Capitol Hosting Solutions, Upstream by Pterodactyl
- Rebased for https://github.com/pterodactyl/wings/releases/tag/v1.5.3
- Fixes improper event registration and error handling during socket authentication that would cause the incorrect error message to be returned to the client, or no error in some scenarios. Event registration is now delayed until the socket is fully authenticated to ensure needless listeners are not registed.
- Fixes dollar signs always being evaluated as environment variables with no way to escape them. They can now be escaped as $$ which will transform into a single dollar sign.
- A websocket connection to a server will be closed by Wings if there is a send error encountered and the client will be left to handle reconnections, rather than simply logging the error and continuing to listen for new events.
* Sun Sep 12 2021 Capitol Hosting Solutions Systems Engineering <syseng@chs.gg> - 1.5.0-1
- specfile by Capitol Hosting Solutions, Upstream by Pterodactyl
- Rebased for https://github.com/pterodactyl/wings/releases/tag/v1.5.0
- Fixes a race condition when setting the application name in the console output for a server.
- Fixes a server being reinstalled causing the file_denylist parameter for an Egg to be ignored until Wings is restarted.
- Fixes YAML file parser not correctly setting boolean values.
- Fixes potential issue where the underlying websocket connection is closed but the parent request context is not yet canceled causing a write over a closed connection.
- Fixes race condition when closing all active websocket connections when a server is deleted.
- Fixes logic to determine if a server's context is closed out and send a websocket close message to connected clients. Previously this fired off whenever the request itself was closed, and not when the server context was closed.
- Exposes 8080 in the wings Dockerfile to better support reverse proxy tools.
- Releases are now built using Go 1.17 the minimum version required to build Wings remains Go 1.16.
- Simplifed the logic powering server updates to only pull information from the Panel rather than trying to accept updated values. All parts of Wings needing the most up-to-date server details should call Server#Sync() to fetch the latest stored build information.
- Installer#New() no longer requires passing all of the server data as a byte slice, rather a new Installer#ServerDetails struct is exposed which can be passed and accepts a UUID and if the server should be started after the installer finishes.
- Removes complicated (and unused) logic during the server installation process that was a hold-over from legacy Wings architectures.
- Removes the PATCH /api/servers/:server endpoint if you were previously using this API call it should be replaced with POST /api/servers/:server/sync.
* Wed Aug 25 2021 Capitol Hosting Solutions Systems Engineering <syseng@chs.gg> - 1.4.7-1
- specfile by Capitol Hosting Solutions, Upstream by Pterodactyl
- Rebased for https://github.com/pterodactyl/wings/releases/tag/v1.4.7
- SFTP access is now properly denied if a server is suspended.
- Correctly uses start_on_completion and crash_detection_enabled for servers.
