Fixed

• Fixes server resource usage stats not being returned correctly by the API endpoint.
• Fixes an exception thrown when attempting to write server installation logs.
• Fixes error handling to provide a more accurate stack-trace in more scenarios where one is missing initially.
• Fixes a memory leak and zombie event listeners when disconnecting from a server's websocket.
• Fixes a race condition when wings is attempting to register/de-register event subscribers.
• Server data directories now correctly have their permissions set recursively when booting Wings.
• Fixes a race condition when a server's console stream was not fully closed before the next power action was started.

Changed

• Server power handling is now handled in a synchronous manner. This avoids endless bugs and race conditions that would crop up if someone triggered two restart processes back to back. The new logic prevents performing any additional power actions until the currently executing action is completed.
• Server disk usage is now correctly calculated when restarting the daemon as long as the server data directory exists.
• Multiple code pathways within the boot process were cleaned up and modified to be less IO intensive and overall easier to reason about as a developer.
• Additional timezone data is now mounted into containers to better improve the ability for instances running to be using the correct timezone.

Added

• Adds basic internal file upload endpoints (these are currently not exposed anywhere in the Panel).
• Added additional process events for installation start and completion.
• Additional CORS allowed origins for the websocket can now be defined in the configuration file.
• Adds the ability to authenticate with a docker registry when pulling images.

Fixed

• Server state is synced with the Panel before performing a reinstall to ensure that the latest information is used.
• Wings no longer crashes when a non-string environment variable value is passed through.
• SFTP server authentication no longer attempts to contact the Panel to validate credentials if the format is known to already be incorrect.
• Some previously missing error stacks are now properly returned when encountered.
• Renaming a file no longer triggers an error if the base path does not exist.
• Disk space is now properly calculated for a server even if it is assigned unlimited space.
• [Security] Prevent symlink files from unintentionally chmodding their target file when a server is booted when the target file resides outside the server data directory.
• [Security] Cleans up multiple code pathways that may unintentionally allow a malicious user to impact files outside their home directory.
• Fixes numerous race conditions during a server's boot process that may lead to unintended data states.
• Fixes an error thrown when attempting to delete a file that points to a symlink outside the server data directory.
• Deleting a symlink will no longer attempt to remove the source file, only the symlink itself.
• Websocket no longer blocks when handling a long running process for a user.

Changed

• Install log for servers is now more detailed and more useful for debugging what might be going wrong.
• Certain file management API endpoints now support passing through multiple paths at once to make mass actions easier to perform.
• Re-worked file walking implementation to not cause a server crash when working with very large directories, and avoid race conditions when recursively walking directories.
• Server configuration structure re-worked to be more manageable in the code base and avoid additional race conditions and complexity while making on-the-fly changes to it.

Added

• Support for configuring additional file mount points in a container via the Panel.
• Support for automated SSL certificate generation when booting the Daemon.
• Added wings diagnostics command.
• New API endpoints to compress and decompress files on a server.

Fixed

• Stacktraces are now displayed once in the error output, rather than twice when certain errors are encountered.
• Additional errors that did not previously output a stack trace have been fixed to output.
• Fixes a bug where server space available would be triggered when creating a new server from a remote configuration before that file location existed on the disk, leading to an error.
• Fixes context timeouts while pulling server docker images. Time was upped from 10 seconds to 15 minutes.
• Configuration file replacement values are now properly de-escaped when writing to the disk. \/no\/more\/slashes
• .properties files are now saved correctly to the disk with newlines, rather than shoved on a single line.
• ./wings configure command can now properly save the configuration to the disk.
• Custom SSL locations are no longer obliterated when making changes to the Node's configuration via the Panel.

Changed

• Exclusive lock is now acquired when performing a server installation to avoid two install processes being triggered at the same time. This also allows an install to be properly canceled if the server is deleted before it is completed.

Fixed

• Server status is no longer sent to all connected websocket clients when a new client connects to the socket.
• Server disk usage is sent back over the socket when connecting.
• Default configuration for the SFTP server is now properly returned to on rather than off
• Server boot is no longer blocked if there is an error fetching the Docker image as long as that image exists on the host.
• The websocket no longer gets locked up when Wings attempts to send an error to the client.
• Fixed a crash loop when an error is thrown during pre-boot phase of server startup.
• Errors with BindJSON in API endpoints are now properly handled and returned.
• Fixed warning about Gin running in non-release mode, even when the binary is running in release mode.

Changed

• Switched logging libraries to output data in a clearer format more suited to the CLI where this application runs.
• Cleaner debug messaging in debug mode from the router.

Fixed

• Default config location settled on /etc/pterodactyl/config.yml; wings will now check all of the previous locations for the configuration and move it automatically to the new location.
• Deleting a server no longer fails the process if the container cannot be found.
• Fixes permissions checking for subusers connecting to the SFTP instance.
• S3 backups now properly send back hash data to the panel.
• Server installation containers are now always deleted, even if the installer process fails for the instance.
• Files and folders with special characters and spaces in them no longer return a 404 error.
• Servers using eggs with bad configurations will no longer cause the daemon to fail booting; these bad configurations are simply skipped over and a warning is emitted into the logs.
• Environment variables passed to containers no longer contain improper quotes around them.
• Matching on array indexes in configurations now works correctly; foo[0] is quietly transformed into the proper foo.0 syntax.

Added

• New banner error message when the daemon is unable to locate the configuration file. This should better clarify what the user needs to do in order to resolve the issue.
• Adds ability to configure the default networking driver used by docker.

Fixed

• Fixes unexpected nil-pointer panic when attempting to start some newly created servers, or any server that was missing a container on the system.
• Fixes memory usage of process being reported differently than the docker stats output leading to some confusion. These numbers should be more correct now.
• Fixes possible nil-pointer panic when detecting a deleted container as being crashed.

Fixed

• Daemon will no longer crash if someone requests a websocket for a deleted server.
• Temporary directories are now created properly if missing during the server installation process.

Added

• Added support for using Amazon S3 as a backup location for archives.

Changed

• Memory overhead for containers is now 5/10/15% higher than the passed limit to account for JVM heap and prevent crashing.

Changed

• Backup functionality made significantly more modular to ease adding additional methods in the future.
• Websocket permissions changed to use same name as in panel.
• Container memory hard-limits are now adjusted up by 15% (< 2G memory), 10% (< 4G memory), or 5% to avoid unexpected OOM crashes for memory heavy games.
• Wings executable is now 80% smaller thanks to better compilation arguments.

Added

• Adds support for ignoring files and directories when generating a new backup.
• Added internal directory walker with callback-continue support.

Fixed

• Fixed linux distro matching when booting the daemon.
• Fixes DNS to be configurable for docker containers that are made for servers.
• Fixes incorrect file truncation when making modifications to a server's configuration files.

Added

• Added support for passing specific threads to the docker environment when running a server.
• Added support for reinstalling an existing server.
• Added support for restarting a server.
• Adds support for transferring servers between daemon instances.
• Added auto-deploy command to fetch configuration from Panel automatically.

Changed

• Server file and backup downloads now hit a direct endpoint with a one-time JWT to avoid proxying large downloads through the panel.

Fixed

• Fixes a go routine causing a memory and CPU leak.
• Fixed improper chown of server directories on boot.
• Miscellaneous fixes to CPU usage, abandoned go-routines, and race conditions.
• Fixes support for Alpine based systems.

Added

• Ability to run an installation process for a server and notify the panel when completed.
• Output from the installation process is now emitted over the server console for administrative users to view.

Fixed

• Fixed bugs caused when unmarshaling data into a struct with default values.
• Timezone is properly set in containers by using the TZ= environment variable rather than mounting timezone data into the filesystem.
• Server data directly is now properly created when running the install process.
• Time drift caused in the socket JWT is now handled in a better manner and less likely to unexpectedly error out.
