1.8.0_to_do_list

Things to do for v1.8.0

Unresolved bugs targeted for this release

Remaining blocker bugs for 1.8.0 final

  • Scaling ASSERTs - Haven't seen them in ages… still a problem?
  • EngineBufferScaleLinear audio degradation (Phil, partially fixed)
  • EngineBufferScaleST repeated buffers, sync loss (partially fixed. Still loses sync when looping.)
  • “scratch” control is asymmetric - https://bugs.launchpad.net/mixxx/+bug/519892 - fixed in fixes_scratch
  • fixes_scratch merge - in beta2
  • Sort out reference counting for TIOs in library caching layer (basesqltablemodel.cpp?) (RJ rocks!)
  • Featured Artists agreement + stats

Very important remaining tasks for beta2:

  • Fix bugs introduced by ssplugin merge:
  • Merge sadness_ssplugin and test build plugins for each platform
  • Merge features_sqlite into trunk
  • Merge features_scriptTimers (with its MIDI thread fixes)
  • M4A Plugin + Downloader (done)
  • Update LibraryTableModel's rows when TrackDAO is accessed, without resetting it. - in features_sqlite branch

Very important remaining tasks for beta1:

  • Missing columns in playlist/crate/autodj views https://bugs.launchpad.net/mixxx/+bug/500474
  • Schema versioning
  • 1.7.0 to 1.8.0 XML→DB Library importer (Patch from Zach)
  • Playlist blurb
  • Crate image blurb
  • Fix as many crashes as possible
  • Crate/Playlist/MissingTracks need working location column.
  • Analyze view text is not readable on dark skins.
  • Escape Prepare view searches, use fetchMore(), search in the GUI thread

Library

Complete the rewrite for basic – but stable – functionality

  • Track DB
    • Needs blacklisting of removed songs.
  • 1.7.0 to 1.8.0 XML→DB Library importer (Zach)

    • Make explicit the cases in which a file outside the Mixxx library is added to the Mixxx library.

    • Make 95% crossfade threshold configurable via preferences.
  • Library Rescan
    • Basic fast hashing rescan
    • Modify Library table to make orphan detection easier later (add extra track_locations table)
    • Add mixxx_deleted to Libray table and fs_deleted cols to track_locations table
    • Use mixxx_deleted to blacklist files “removed” from the Mixxx library.

  • Tagging (not file metadata tagging)
    • DAO for tags
    • Feature for tags
    • Drag-n-drop to sidebar
    • Tag table model

    • Write a CueDAO/Cue service.
    • Make TIO's have a list of Cue's
    • Make TrackCollection save a TIO's Cue's on track save (via CueDAO)
    • Ditch EngineBufferCue
    • Extend EngineBuffer to allow outside addition of EngineControls
    • Write CueControl, created by Player, added to EngineBuffer as an EngineControl

    • Waveform / waveform overview loops and cues
    • Update skins
  • Minor Bugs
    • Duration Delegate should format seconds as %02d.
    • Sorting is not case insensitive (e.g. on Title)

    • Numark Total Control
    • Reloop Digital Jockey 2

M4A

  • Solve packaging issues
  • Solve Windows X64 libfaad2 dll building issues (embedded asm vs intrinsics) - may be able to split the assembly code into its own file and assemble that separately - Successfully worked around it by disabling the (5 lines (!) of) assembly code and using the supplied C/C++ code
  • Fix SoundSourceM4A decoder issues

Misc

  • Bundle libsndfile's trunk code into Mixxx for FLAC fixes? (Since there's no scheduled release date for the fixed libsndfile)
  • Collect enhanced controller mappings from forum posts for wider testing
  • Fix compilation on Windows x64 to correctly use SoundTouch optimizations (or not depending on optimize flag) - Sean
  • Update user manual
  • Can someone with some pull PLEASE tell C-Net to update their Mixxx download page?! 82 downloads a week for Mixxx 1.5.0.2 does not make us look good. - Adam took care of it
  • Upload 1.8.0 final to C-Net and update our home page link there (still points to SF)

MIDI Sub-system tasks

Remaining tasks here are just polish and are not required for release.

  • Move all PortMIDI calls to one thread (the script engines can not directly call send*Msg anymore.) See this.
  • Save multiple device files correctly, deleting previous .midi.xml files in .mixxx/
    • Save the meta-data (controller ID, author, description, etc…)
      • First make a GUI object that lets the user modify the author and description
    • Find a more appropriate place to save the files other than the MidiDeviceManager destructor Now done (only) when OK is clicked in the prefs
    • Need a way to keep track of duplicate devices so separate files can be saved: Have DlgPreferences::slotApply() call MidiDeviceManager::saveMappings() which does them all in one shot (and can thereby keep track of them)
  • Load those files correctly
    • Load files for attached devices regardless of if they're activated or not.
  • Replace MidiCategory with MidiStatusByte permanently (see mididevice.cpp line 195.)
  • MIDI Scripting: Pass the <group> value from the XML to the script as an additional parameter (at the end of the list so existing scripts are not affected.) - Done by Phil
  • Add MIDI script timers
  • Implement alpha-beta smoothing filter in the Engine (currently in scratch.* functions in the common script file) with fixed-interval updates. (I.e. if no new data arrives in the interval, assume the control is stopped and feed that data to the smoothing function.) - Done in the MidiScriptEngine for relative controls in 1.8.0
  • GUI changes:
    • Replace “Activate” button with an “Enabled” check box
    • Display enabled devices in the tree in bold text
    • Auto-change “Output” drop-down based on auto-selected output device in MidiDevice(Manager) when the device is enabled - Albert
    • Make “Output” drop-down take effect when changed - not happening in 1.8. Output drop-down is disabled for now.
    • Persistent mapping preset drop-down (don't return to “…” unless Clear All is pressed. If the user tweaks the mapping, say “<custom>” or something.)
    • Also clear the list of MIDI scripts when Clear All is pressed
    • Do not commit changes to the MIDI mapping tables unless OK is pressed in the preferences window. (I.e. allow pressing the Cancel button or the X on the preferences window to restore the MIDI mappings to their previous states.)
