vibe.d 0.7.19 release

Header image
Wed, 09 Apr 2014Apart from working on the latest DMD versions, this release includes an important security enhancement in the form of new experimental code for SSL certificate validation. Other major changes include many improvements to the Diet template compiler, various performance improvements, a new FileDescriptorEvent to interface with other I/O libraries, a new web interface generator similar to the REST interface generator, many improvements to the Redis client, and a bunch of other fixes and additions.

Features and improvements

  • Compiles with DMD 2.065 (and the current DMD HEAD)
  • API improvements for the SSL support code
  • Implemented SSL certificate validation (partially by David Nadlinger aka klickverbot, pull #474)
  • Removed the old EventedObject interface
  • Implemented support for string includes in Diet templates (idea by Stefan Koch aka Uplink_Coder) - issue #482
  • JSON answers in the REST interface generator are now directly serialized, improving performance and memory requirements
  • Reimplemented the timer code to guarantee light weight timers on all event drivers
  • Libevent2TCPConnection now has a limited read buffer size to avoid unbounded memory consumption
  • Fixed the semantics of ConnectionStream.empty and connected - empty is generally useful for read loops and connected for write loops
  • Added an overload of runTask that takes a delegate with additional parameters to bind to avoid memory allocations in certain situations
  • Added vibe.core.core.createFileDescriptorEvent to enable existing file descriptors to be integrated into vibe.d's event loop
  • HTTP response compression is now disabled by default (controllable by the new `HTTPServerSettings.useCompressionIfPossible)
  • Removed the deprecated sslKeyFile and sslCertFile fields from HTTPServerSettings
  • Removed the compatibility alias Signal (alias for ManualEvent)
  • :htmlescape in Diet templates is now processed at compile time if possible
  • Added support for Rebindable!T in isStronglyIsolated and isWeaklyIsolated - issue #421
  • Added RecursiveTaskMutex
  • Throwable is now treated as weakly isolated to allow passing exceptions using vibe.core.concurrency.send

  • Added support for storing arbitrary types in Session
  • Moved the REST interface generator from to
  • Added a new web interface generator (vibe.web.web), similar to vibe.http.form, but with full support for attribute based customization

  • Added requireBoundsCheck to the build description
  • Added assertions to help debug accessing uninitialized MongoConnection values
  • Added logFatal as a shortcut to log called with LogLevel.fatal (by Daniel Killebrew aka gittywithexcitement) - pull #441

  • The libevent2 and Win32 event drivers now outputs proper error messages for socket errors
  • Changed setTaskEventCallback to take a delegate with a Task parameter instead of Fiber
  • Added a Task.taskCounter property
  • AutoFreeListAllocator.realloc can now reuse blocks of memory and uses realloc on the base allocator if possible
  • HTML forms now support multiple values per key
  • Inverted the no_dns parameter of EventDriver.resolveHost to use_dns to be consistent with - issue #430
