Changelog¶

3.0.8 (TBR)¶

Additions and improvements

• WebGL: Support added for WebAssembly.Table language feature.
• [HTTP2] Added NO_RFC7540_PRIORITIES to the known settings.
• [HTTP2] HTTP2SettingsRegistry will ignore unknown keys by handling them gracefully instead of throwing an exception.
• CookieJar now has an IsEnabled field to be able to disable cookie handling completely.
• Removed unused BlockingTCPStream implementation.

Fixes

• Save current uri before handling redirection, otherwise PerHostSettings might return with the wrong setting for the current connection.
• Don't close the underlying connection when we just upgraded/switched protocols.
• (#195) Fixed deadlock in BlockingDownloadContentStream.
• (#189) Fixed warning in documentation under JetBrains Rider.
• (#190) HTTPRequest's Dispose is now an internal method.
• HTTP/1 connection is closed when HTTP1ConnectionSettings.TryToReuseConnections set to true even if the connection is upgraded.
• When checking for TryToReuseConnections, save current uri before handling redirection, otherwise PerHostSettings might return with the wrong setting for the current connection.

3.0.7 (2024-03-27)¶

Additions and improvements

• Merged two request events (Queued and Resend) into one.
• If the response is with an unknown length (neither chunked or has a content-length header) and the tcp connection is closing, read all available data and serve the response as completed.

Fixes

• Fix for Incorrect Brotli handling for AndroidMono (#187) .
• Continue download after displaying a warning about download content stream beeing full.
• Fixed case where Database's FindContentAndMetadataLocked throws an exception. It will handle the exception, display it, but deletes the corrupted DB entry to not try to use it the next time.
• Don't log an error if HTTPRequest's state changes and the threading mode isn't set to UnityUpdate (#188).

3.0.6 (2024-02-09)¶

Fixes

• HTTP2: Fixed NullReferenceException when an UploadProgress event is defined for the request.
• Fixed case where not all available connection slots are used to server queued requests

3.0.5 (2024-01-03)¶

Additions and improvements

• Added constructor to the MultipartFormDataStream to allow setting custom boundaries.

Fixes

• Fixed boundary generation and sending for MultipartFormDataStream.
• Fixed WebGL issue introduced in v3.0.4, where requests are stuck while checking the local HTTP cache.

3.0.4 (2023-12-22)¶

Additions and improvements

• Implemented a new algorithm to pre-establish connections. This primarily affects HTTP/2 connections, which can handle multiple requests simultaneously. Starting from this version, the plugin is capable of opening more than one HTTP/2 connection when a large number of requests are queued.
• Added a new field MaxAssignedRequestsFactor to HostVariantSettings. This field aids in fine-tuning the creation of new connections based on the number of queued requests.
• Moved the first local HTTP cache check to a background thread. In exchange of some slight delay to remove overhead from the main Unity thread.
• Added a few more logging.

Fixes

• (#183) Handle unrecognized content-encoding values gracefully and serve the content as-is.
• HTT2: Fix case where a request's Processing state isn't processed in time and as a result HTTP2Stream made decisions based on the old state and didn't finished the request.
• HTTP Cache: HTTPCache.CanServeWithoutValidation wasn't thread-safe.
• HTTP Cache: Even with DisableCache, a failed request still checked the local cache whether the content can be loaded.
• HTTP Cache: In some rare cases, the first read from the cache happened before FileConnection could register its callbacks and as a result the assigned request never finished.

3.0.3 (2023-12-08)¶

Additions and improvements

• Updated WithCredentials' documentation.

Fixes

• Under Android (and possible under other non-windows platforms) when the network is unreachable Unity doesn't call the callback passed to BeginConnect.

3.0.2 (2023-12-04)¶

Fixes

• Fixed case where TCPStreamer would block indefinitely if there's no sending in progress and receives more data to send than MaxBufferedWriteAmount
• WebGL: Fixed case where if there was any content-encoding (gzip for example), the actual content accessible through XHR's response had different length (it's uncompressed) than what the server sent with the content-length header.
• Fixed compile warning/error when building for WebGL
• Typo fix in ProxyDetectionMode: renamed Continouos to Continuous

3.0.1 (2023-11-28)¶

Additions and improvements

• (#165) Use short-living threads for simple HTTP/1 GET requests
• Added short and long-living thread counting for a possible threading profiler in the future
• Log out exception in the HTTPCahe constructor only when diagnostic logging is enabled

Fixes

• Fixed support for BESTHTTP_DISABLE_ALTERNATE_SSL.
• Fixed case where the content-encoding header is sent to the higher layer and the generic HTTP1 response class tried to decompress an already decompressed content

3.0.0 (2023-11-01)¶

Additions and improvements

• New namespace hierarchy.
• Added DNSCache implementation to speed up consecutive connection processes.
• Added support for DNSCache to manually store and retrieve entries.
• Added new Negotiator class help building new plugins that doesn't use HTTP, but require the same lower-level infrastructure.
• Added new TCPRingmaster class to speed up TCP connection process by sending out multiple tcp connection requests and use the first connected one.
• Reimplemented connection logic to use the new DNS cache, negotiator and tcp-ringmaster.
• Reimplemented network read and write operations. Instead of blocking Reads&Writes, now the plugin uses non-blocking functions. This enabled implementing new ways for downloads and uploads. There's forward and backward feedback between the low level tcp layer and higher level connection layers. If the download-stream's buffer is full, it can notify the tcp layer that it can resume receiving from the server.
• Reimplemented HTTPCache, it's got more robust and future proof.
• (#69) Now it's possible and easy to populate the local HTTP cache.
• Added new, cleaner samples for both old and new features.
• Halved active threads per connections.
• Added Memory and Network profilers.
• (#126) Added UniTask integration

Removals

• Removed old, cluttered samples.

Fixes

• Fixed chaos around different upload sources (RawData, Forms, UploadStream) and unified them in one UploadStream.
