Opening, creating, closing or reverting a session in the middle of a
take dropped the recorder: the take was written to disk but never added
to any session. Quitting mid-take did the same, and on_exit didn't
finish the take either.
New, Open, Close, Revert and Quit now wait for the take: the engine
refuses them with "stop recording first", and their menu items are
greyed out while recording, as is Recover in the recovery window. Any
exit that still happens mid-take (closing the window, the system
quitting the app, a remote quit) finishes the take first and keeps the
session, take included, in the autosave folder for the next launch.
Nothing caught a panic outside a command: one in the interface's frame
code ended the process in that frame (exit code 101), losing every
unsaved change, and the log got a single line with no backtrace.
Each frame's logic and drawing now run guarded. A panic there autosaves
the session (once per change, so a bug that repeats every frame doesn't
flood the disk), says so in the status line and lets the app carry on.
If the app goes down after all, the autosave is offered at the next
launch. The panic hook now logs a backtrace.
Autosave wrote every session called "Untitled" to the same
Autosave/Untitled folder and reused audio files there by source id, so
a second untitled session, or a take recorded after an undo, could be
autosaved with another take's audio. Its first run also copied all of
the session's audio again. Nothing ever offered an autosave back
(latest_autosave had no callers), so after a crash the work could only
be found by digging in the settings folder.
Each open session now autosaves to a folder of its own, locked while
the session is open. Audio already saved with the session is referenced
where it is; audio that exists only in memory is copied once per
recording or render. Saving, closing the session, opening another and
quitting with SoundCraft's Quit delete the folder. A crash, or an exit
that skips Quit with unsaved changes, leaves it behind, after one last
autosave when SoundCraft gets the chance. At the next launch,
SoundCraft offers each kept folder, newest first, to recover or
discard. Recovered work opens as an unsaved version of the session it
came from, so Save writes it back there; unsaved changes in the session
it replaces are kept the same way. Folders older than their session
file are dropped.
write_automation merged a pass's points under one key, but the fader
driving the pass merged under its own, so each frame of a ride started
two new undo steps: one second of riding made 120, and in two seconds
everything before the pass was gone from the 200-step history. Stop's
last point was a step of its own as well, because every command,
transport.stop included, ended the gesture.
Engine::hold_merge makes every merged gesture take the held key until
it is released. While playing with a track in a write mode,
write_automation holds the pass's key, so the pass and whatever is
dragged during it are one undo step. A command now ends a gesture only
when it changes the document, so Stop no longer splits the pass it
ends.
Close Session, New, Open, Revert, Quit, the window's close button,
dropping a session file on the window and opening one from the Workspace
window all replaced or closed the session without asking, so unsaved
edits were lost (#136). They now ask first: Save, Don't Save or Cancel.
Save on a session that has never been saved goes through Save As, then
carries on. Revert asks for confirmation instead, and Revert to Saved is
unavailable until the session has a file. A take being recorded is
stopped first, so it counts as a change. The web build has nowhere to
save, so it offers only Don't Save and Cancel. Calls from the control
channel, MCP and the CLI never ask.
Selecting, locating, zooming and scrolling no longer mark the session
modified, so the question only comes after real edits. Undoing back to
the saved state makes the session clean again. The engine compares the
document with the one last opened or saved, ignoring the selection, the
playhead and the zoom, once per revision.
Fixes#136
- Pinch and Cmd+scroll zoom the timeline around the pointer. egui 0.36 turns
both into zoom_delta, so the old Cmd+scroll branch never ran; Shift+wheel
pans sideways again for the same reason.
- Two-finger panning keeps the sub-sample remainder, so slow motion still
moves at the closest zoom; the scrollbar drag pans the same way (its range
now takes in the view, so the thumb stays in the bar), and the rulers pan
too. Panning stays open-ended to the right, as before.
- A swipe keeps to the axis it starts along, so panning doesn't drift between
tracks and scrolling doesn't drift in time. The larger share of its first
6 points decides until egui reports the scroll over: the fingers lift, or
150 ms pass without wheel events.
- The MIDI editor scrolls by the point instead of rounding each frame's delta
to whole rows (slow swipes did nothing), and its range fits the panel
(pitch 0 could not be reached; a taller panel showed blank rows).
- Zoom and scroll write through `Engine::zoom_mut` (`view` commands): no
playback resync (a session copy sent to the audio thread every frame), no
copy of the whole session per frame, no journal entry per frame, and no
end to an undo gesture (scrolling during an automation pass made each
write its own undo step). New `view.zoom_by {factor, x?}`;
`view.scroll` saturates; Fill Window and Zoom to Selection stay within the
zoom range (zooming out after them on a long session zoomed in).
- Control channel: `ui.scroll` (trackpad swipe or wheel notches) and
`ui.zoom` (pinch); `session.inspect` reports zoom.
Nothing in the Clip List could be removed: neither its files nor its clips
had a delete action, so everything stayed listed.
- New `clip.clear` (Cmd+Shift+B, the Clip List Clear shortcut in Pro Tools),
also offered as Clear… on every Clip List row's right-click menu. A clip
leaves its track; a file leaves the session with its decoded audio and is
never deleted from disk. One undo step brings everything back.
- As in Pro Tools, Clear asks first. The dialog names what goes, including
the clips on any track or playlist that still play a file being removed:
they are removed too. Programmatic calls never open it; they pass
`with_clips: true` to remove a file still in use, and fail without
changing anything otherwise.
- File rows can be selected now (`edit.select {sources}`, kept in
`EditState::selected_sources`); with no ids, `clip.clear` acts on the
Clip List selection.
- Remove Warp and re-warping ignore a stored original whose file has been
cleared, so they never point a clip at a missing file.
Testing on macOS showed that the exit-handler fallback comes too late for a
plugin that has been used: with HALion Sonic inserted on a track, its bundleExit
segfaults, and both the app (on quit) and soundcraft-cli (after a bounce) exited
with 139. A plain scan was fine. Exit handlers run in reverse order of
registration, so state the plugin set up while in use is presumably torn down
before the host's handler runs.
soundcraft_vst3_host::shutdown() runs the module exits up front, and
soundcraft_engine::shutdown_plugin_hosts() calls it. The app calls that once the
event loop has returned (the player and its plugin instances are gone by then),
and the CLI once its subcommand has. The exit handler stays as the fallback for
other exits, such as test binaries.
The fixture can now set up state lazily the way such plugins do
(VST3_FIXTURE_LATE_STATE), and module_exit_shutdown checks both sides in child
processes: with shutdown() the exit is clean, with only the exit handler the
fixture reports the late teardown. Contract violations now end the process with
status 3 instead of an abort, so that expected failure leaves no crash report.
