going public

This is by far the largest release to date, covering about two years of development when combined with the two other appls senseye and durden. In addition to a number of bugfixes, optimization and refactoring, these are the biggest changes:

General

• Much improved documentation, automated testing, build tracking and tagging.
• Re-organized large parts of the source tree
• Switched majority of component licensing from GPL to BSD
• AWB / Gridle moved out to own .gits, defunct/unsupported
• Added support for LWA, lightweight arcan. A special build that uses another arcan instance as display server.
• Much improved support for HDPI and mixed-DPI displays

Lua

• New functions: net_discover, video_synchronization, resize_video_canvas,
  video_displaydscr, video_displaymodes, map_video_display, system_identstr,

  CRASH_SOURCE
• Calctarget callback table get, histogram_impose and frequency
• Frameserver_terminated events renamed to terminated
• Support for coverage tracking trace build
• Added color support to output messages
• Added interpolation function specifier to move/rotate/blend/resize
• Transformation chains can have callback tags associated with completion, this also works as a timer implementation.
• Added support for native/accelerated cursor rendering
• System_collapse for switching running appl or dropping all resource
• Allocations that are not strictly connected to frameservers
• _display_state callback
• Input class for frameserver/remoting originated input (cursor_input, key_input)
• Net discovery events propagated
• Automated frameserver- looping dropped in favour of manual management on terminated events
• Monitor state format properly escape Lua strings
• Text rendering functions provide additional metrics and has a tabled version where %2 indices ignore format string characters
• Link_image can now specify anchor point

Engine

• Database module rewritten, target/configuration/appl key-value store
• Namespace rewritten, RESOURCE/APPL split into multiple fine-grained namespaces
• Interpolation state exposed as shader built-in
• Output dimensions exposed as shader built-in
• Better transformation caching and dirty invalidation
• Bugfixes to 2D/3D picking
• Support for post- Lua init hook scripts (primarily intended for testing and automation purposes).
• First refactoring of memory allocation resources using different interface that tracks alignment, metatype etc.
• Support for adoption / fallback application in the event of an error in the Lua state machine
• Dropped support for framequeues
• Font rendering support for default- system font and specifying format related to system font
• Fallback font chains to switch other fonts when glyphs are missing
• Cheap, "shallow" clipping added to reduce stencil- buffer use
• More fine grained control over frameserver data routing
• Support for shader instancing through uniform groups
• Framesets now act as null_surface + sharestorage calls

Platform

• EGL-GLES split into regular EGL-GLES primarily for ARM devices, and the Linux/KMS specific EGL-DRI with the distant relative EGL-NVIDIA.
• Interface expanded to support multi-monitor, dynamic synchronization switching
• X11 and Linux (evdev) platform support expanded with better input management
• Support for DRI render-nodes, accelerated buffering passing
• OpenGL used stripped from video/3d/frameserver into AGP (arcan graphics platform) to support lower level graphics APIs and software rendering.

Shmif

• Support for non-authoritative connections via CONNPATH and CONNKEY
• Support for multiple- segments,
• More aggressive cookie/dynamic integrity check
• Cleanup / simplify connection and setup API
• Shmif resize heuristics switched to reduce stalls / latency
• Support for multiple video buffers / segment
• Support for multiple audio buffers / segment
• Support for Communicating buffer dimensions
• More fine-grained control over I/O multiplexation, guard threads, synchronization, blocking vs tearing
• Type-model changes, SEGID can register as: LWA, NETWORK_SERVER, NETWORK_CLIENT, MEDIA, TERMINAL, REMOTING, ENCODER, SENSOR, GAME, APPLICATION, BROWSER, VM, HMD_SBS, HMD_L, HMD_R, POPUP, ICON, TITLEBAR, CURSOR, ACCESSIBILITY, CLIPBOARD, CLIPBOARD_PASTE

Frameservers

• Added terminal frameserver
• ARCAN_FRAMESERVER_DEBUGSTALL switched to allow infinite or specific- sleep
• VNC server support added to encode
• Remoting frameserver added (primitive at the moment, support vnc client)
• Decode_ default switched from av/ffmpeg to libvlc
• Libretro graphing moved to a possible debug secondary segment
