7.2.0

• Compatibility with ARM architecture
• Bug fix: getUri etc. in the new compact http server mode
• Bug fix: failed read in the new compact http server mode

7.1.0

Release notes, 7.0.0 (2024-06-01)

StreamingServer has been merged to HttpServer

• receiveInChunks iterator renamed to receiveStream
• maxrequestlength renamed to bufferlength
• newHttpServer does not anymore take hascontent parameter, but instead:
• newHttpServer takes contenttype parameter:
  • Compact (the default mode): Equivalent to previous hasContent=true mode, where whole request body must fit into the buffer
  • NoBody: Equivalent to previous hasContent=false mode, for optimized handling of requests like GET that do not have a body
  • Streaming: Equivalent to previous StreamingServer, where you have to read the body yourself using the receiveStream iterator
• startDownload-continueDownload-finishDownload combo renamed to replyStartChunked-replyContinueChunked-replyFinishChunked

Header processing streamlined

• parseHeaders and parseAllHeaders obsoleted
• newHttpServer takes headerfields parameter, listing header fields that you need
• in request handlers http.headers StringTableRef is automatically populated with needed header key-value pairs

New MultipartServer

• handles multipart/form-data for you as neatly parsed
• operates in streaming manner, allowing huge uploads without blowing up RAM

Improvements to websockets

• If you do not accept a connection (reply false in upgradeCallback), a HTTP 400 reply is now automatically sent before the socket is closed
• PONG is now automatically replied to PINGs, sendPong proc is removed
• default reply values changed, now timeoutsecs = 10, sleepmillisecs = 10
• if all in-flight receivers are blocking, now suspends for (sleepmillisecs * in-flight receiver count) milliseconds
• fixed isMessage bug

6.1.0

• fixed nimble path
• fixed README example
• new receiveInChucks iterator in streamingserver for receiving big data, for example POST data that does not fit in main memory
• new startDownload-continueDownload-finishDownload combo in streamingserver for sending big and/or dynamic responses as Transfer-Encoding: chunked
• new and upgraded streamingserver examples as required

6.0.0

• major rewrite, breaking changes here and there, consult migration guide and code examples.
• dispatcher(s) can now be replaced just by changing import(s)
• every TCP port is now served by different server, allowing port-by-port configuration of resource usage
• non-blocking I/O with cooperative multithreading now used everywhere
• new suspend procedure for allowing other threads to run also when waiting for I/O in user code
• overall compatibility with Nim version 2.0
• single-threaded mode is no more
• TimerCtx is no more

5.1.0

• new multiSend proc for WebSockets: can be called from multiple threads in parallel
• better default logging
• other fixes

5.0.0

• Breaking change: If you use timer handlers, you must now import guildenstern/timerctx
• Refactored timer handlers to use same logic as other handlers
• New proc removeTimerCtx for stopping timers
• new logging implementation supporting multiple log levels, -d:fulldebug obsoleted
• performance optimization: threadpool now incorporates a (lock-free) task queue

4.0.0

• serve proc now accepts the amount of worker threads to use
• registerThreadInitializer is now a global proc (not tied to a GuildenServer)
• ctxWs web socket upgrade now accepts a callback closure (instead of initial message to send)
• can listen to multiple ports even with same handler (just register different handler callback proc for each port)
• new ctxBody handler for efficiently handling POST requests.
• new isRequest proc for efficiently inspecting request content
• new custom threadpool
• code fixes and cleanups

4.0.0-rc1

• registerThreadInitializer is now a global proc (not tied to a GuildenServer)
• new setWorkerThreadCount proc for (optionally) setting the amount of worker threads
• new isRequest proc for efficiently inspecting request content
• removed dependency on stdlib threadpool
• code fixes and cleanups
