[linux-audio-dev] ardour 0.9beta23 released

Well, its time for another release of Ardour. This release is another milestone: it marks the end of all bugs that were slated to be solved before the 1.0 release. The plan from here is to wait for about a few days to allow testing of this release and minor (cosmetic) bug fixing to continue, and then ardour 0.99 will be released. After that, release engineering (install process, new user experience) will be all that stands between us and release 1.0rc1, which will hopefully be the last release before 1.0. Please note: there is no claim that Ardour is bug free. The bug list for 1.0 was drawn up with the goal of making sure that the vast majority of new (and existing) users of Ardour will have a rewarding, powerful and largely problem-free experience recording, mixing and producing music. There are still substantive (as well as trivial) issues that require solutions, but the development team is anxious to move on to the GTK2 port so that we can make Ardour look as shiny (shinier?) as Rosegarden :) This is an important release for people who work in locales that do not use the period (".") as a decimal separator (i.e. decimals written as "1,5" rather than "1.5"). It is the first version that we believe is now truly locale-safe against data corruption caused by LC_NUMERIC's affect on stored data formats. Enjoy, there's more to come :) --p * fix a truly appalling coding error in all uses of LocaleGuard - people who run ardour with LC_NUMERIC set to something other than en_US.UTF-8 will probably have continued to suffer from locale-based problems because of this problem. * fix nesting of LocaleGuard objects to provide yet more fixes to LC_NUMERIC problems * add new flag for custom canvas items that do not require an automated redraw when arguments are set. * rework canvas "simple rect" item to optimize redraws as resizes occur, and use FAST_PAINT_BOX to speed up drawing slightly. it is possible (likely?) that this will help some system performance issues when recording multiple tracks at once. * rationalize how the "s" (split) operation works. - if the mouse pointer is inside a regionview, that region is split - if the region was part of the selection, then a) all regions covering the mouse pointer time position are also split b) the selection is cleared after the split - if the region was not part of the selection, then the selection is left unchanged after the split * if auto-connect inputs is in use, only connect the first N inputs where N is the number of physical inputs found by JACK * fix grotesque error in use of STL reverse iterators that messed up any use of AutomationList::truncate_end(), causing horrible corruption of the control points. * fix long-standing problems with region gain line visibility (as-is, plus after-trimming) * reimplement Route::_reset_plugin_counts() to use a slightly simpler algorithm and allow zero-input plugins ("instruments") as the first in the chain * fix problem with metering when using zero-input plugins * fix problems with failed remove of redirects * make region editor clocks insensitive at the right times * store relative names in session file for connections, allowing re-establishing internal connections when connected to JACK using a different client name * fix major thinko bug with Curve::spline_eval() that caused a complete failure if the Curve had 0, 1 or 2 control points. * Karsten's fixes for crossfades, plus a modified version of his TimeAxisViewItem "selected" fix. * automation track "controls context menu" now includes "clear" and auto-state submenus, so that full control even using a small track height is possible. * require inserts/plugins to either be mono-input or match the active streams at that point in the route. this means you cannot insert a 2in plugin on a mono track without a 1in/2out splitter preceding it. we will change this in a future (post-2.0) version of ardour so that the splitter is added automatically in a hidden way. * fix naming of sends/inserts to avoid duplications. * removed redundant expansion arrow from TimeAxisView * when a region overlaps another region but is wholly within the other, create hidden, immutable 64-frame xfades at both boundaries. (works, but some more work needed on corner cases and thoroughly testing normal overlap xfades) * fix off-by-1 errors in drawing canvas rect objects (affects rubber band selection, range selection and more) * corrected off-by-1 error in position of fade out polygon within regionviews * expanded height of per-track selection rects to full track height * muted regions never write silence, whether they are opaque or not. * added "Mute" and "Unmute" to region ops menu * fix bug in Editor::cursor_to_selection_{start,end} that prevented the function from working in range mode * delete AudioEngine at exit (and thus call jack_client_close()) * make "active" check menu item on mixer strip "name" context menu be in correct state at startup * popup error message if clone or copy of redirects fails * prepend "!" to the displayed name of a muted region * newly created regionviews follow the current "show waveforms" setting * relevant internal-overlap xfades are invalidated by layering changes * all (relevant) xfades are invalidated by muting changes * another almost-complete reimplementation of plugin count handling - no visible changes intended - we now compute counts before changing the counts - if the configuration is impossible, things are left unchanged - if the configuration is possible, we set the counts - all failed reset_plugin_count() calls should leave the redirect lists in their original state * reimplement region layer changes to avoid visible "illegal" state with two regions in the same layer * fix bug with soloing that would cause solo states of tracks|busses in the incorrect state if busses|tracks were also soloed while a track|bus was un-soloed. * make "active" check menu item in track controls context menu be in correct state at startup * use nick mainsbridge's brilliantly simple "later regions are on higher layers" idea * remove all explicit control over layering from ardour/gtk * fix nasty thread/race condition bug when building peakfiles for imported/embedded audio. two threads could be reading from the same file at the same time, and under some circumstances could stomp on each others activities. * fix potential (suspected) race condition associated with peakfile request submission and handling. may affect some reported "hangs" when importing/embedding audio. * actually use two-stage regionview creation (rects first, waveforms later) by refactoring SndFileSource's use of its primary mutex. makes regionviews * fix attempt to access an illegal column of the file selector in the library/file browser. * add pthread id to "posix signal received" message * require use of --new/-N flag to create new sessions from the command line * remove "exiting foo thread" and "stopping bar thread" messages * from shutdown, don't kill the GUI thread if its not running * add EnvelopeChanged Change to AudioRegion, playlist saves state when this or *any* region change occurs. this fixes a class of bugs where undo after a region was removed fails to fully restore the region's state. * remove debug output from Gtkmmext::NewSaveDialog
