* terminal: use Invalidate and QueueRedrawTim Culverhouse2022-10-071-14/+2
| | | | | | | | | | | | | | | | | | | The terminal widget uses it's own redraw logic to improve performance. With the addition of a main event loop, the redraw logic can happen in the main loop via the standard Invalidate logic. Use the Invalidate method to mark aerc invalid, and immediately trigger a redraw with ui.QueueRedraw. The follow up call to QueueRedraw is needed because the terminal update happens in a separate goroutine. This can result in the main event loop finishing it's process of the current event, redrawing the screen, and the terminal having additional updates to be drawn. This fixes race conditions by drawing and calling screen.Show in a separate goroutine. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

* compose: avoid double lock in MouseEventTim Culverhouse2022-10-051-2/+5
| | | | | | | | | | | | | The MouseEvent locks the composer, and also calls FocusEditor which attempts to lock the composer. This results in a deadlock. No need to call FocusEditor which takes a name as parameter and needs to iterate over all editors to find the correct one. We already have the headerEditor object, use it directly.

* viewer: option to not mark message as seenKoni Marti2022-10-041-2/+2
| | | | | | | | | | | | | | | | | Add option to open a message in the message viewer without setting the seen flag. Enables the message viewer to be used as a preview pane without changing the message flags unintentionally. Before, the message viewer would set the seen flag by default. The IMAP backend will now always fetch the message body with the peek option enabled (same as we fetch the headers). An "auto-mark-read" option is added to the ui config which is set to true by default. If set the false, the seen flag is not set by the message viewer.

* bindings: properly check for exKey keystrokesTim Culverhouse2022-10-031-1/+9
| | | | | | | | | | | | | | | | | | | | | When checking for an exKey, aerc inspects the key and the rune of the event vs the exkey binding. Runes should only be inspected if the key is a tcell.KeyRune. Some Ctrl-[:alpha:] keys report a rune in tcell, but aerc does not have these bound to the keystroke definition. Only <C-x> has a rune bound, and is one of the very few <C-> keys that can actually be bound to exKey Only compare the Rune field if the key is of type KeyRune. Otherwise, compare the Key. Also compare any modifiers with the keystroke/key event. These changes allow for any control or alt key combination to be bound to the exkey. Update documentaiton to reflect that the default keybind is ':', and not <semicolon> Fixes: https://todo.sr.ht/~rjarry/aerc/67 Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

| | | | | | | | | | | | | | | | Subsitute the format specifier %w for %v in the logging facility.

* terminal: fix race conditions on access to cmdTim Culverhouse2022-10-021-35/+11
| | | | | | | | | | | | | | | | Upgrade tcell-term to v0.2.0 Use Start method from tcell-term. This prevents aerc from needing to wait until the command has started to continue. The tcell-term start method blocks until the command is started, similar to cmd.Start. By doing so, we prevent a race condition between aerc and tcell-term on access to cmd.Process.

* notmuch: move logic for dynamic folders to backendKoni Marti2022-09-291-13/+0
| | | | | | | | | | | | | | | Moves logic for creating dynamic folders from the dirlist widget to the backend. Since dynamic folders are notmuch-specific, the notmuch backend should be responsible for correctly setting up those folders. It does that by sending two DirectoryInfos: the first to create the message store, the second to fetch the directory content. This approach also fixes a deadlock introduced by 716ade8968715 ("worker: lock access to callback maps").

* exline: don't draw completions for keybindsTim Culverhouse2022-09-292-3/+20
| | | | | | | | | | | | | | | | | | | The exline widget works by matching actual keystrokes to a map of keybinds, and if a match is found sending simulated keystrokes through aerc. This has the effect of aerc thinking we are actually typing in the expanded command, and aerc attempts to draw the completions. This results in even basic navigation having two screen draws: For example, pressing 'j' to select the next message (:next), draws once for the initial key event and state change, and again after the completion debounce timer. Disable tab completion while aerc is simulating keystrokes. If the exline still has focus after simulating keystrokes, restore tab completion.

* terminal: don't invalidate on EventWidgetContentTim Culverhouse2022-09-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The terminal widget uses it's own internal event handler to redraw itself for improved performance. The event handler draws, updates the screen, and invalidates. The last invalidate is redundant: Invalidating has the result of telling aerc to redraw the screen. A race condition can occur where an event is emitted from the terminal and the terminal is closed before the event is handled. This results in handling the event after the terminal is closed, and a panic: panic: Attempted to invalidate unknown cell goroutine 54685 [running]: git.sr.ht/~rjarry/aerc/lib/ui.(*Grid).cellInvalidated(0xc00b0a34a0, {0xbb8f10?, 0xc00360cd80}) git.sr.ht/~rjarry/aerc/lib/ui/grid.go:287 +0x175 git.sr.ht/~rjarry/aerc/lib/ui.(*Invalidatable).DoInvalidate(0xc0002e7900?, {0xbb8f10?, 0xc00360cd80?}) git.sr.ht/~rjarry/aerc/lib/ui/invalidatable.go:22 +0x82 git.sr.ht/~rjarry/aerc/widgets.(*Terminal).invalidate(...) git.sr.ht/~rjarry/aerc/widgets/terminal.go:93 git.sr.ht/~rjarry/aerc/widgets.(*Terminal).HandleEvent(0xc00360cd80, {0xbb4ba0?, 0xc006022690?}) git.sr.ht/~rjarry/aerc/widgets/terminal.go:192 +0xd2 github.com/gdamore/tcell/v2/views.(*WidgetWatchers).PostEvent(...) github.com/gdamore/tcell/v2@v2.5.3/views/widget.go:113 github.com/gdamore/tcell/v2/views.(*WidgetWatchers).PostEventWidgetContent(0xc0001b9360, {0xbbc950?, 0xc0001b9320}) github.com/gdamore/tcell/v2@v2.5.3/views/widget.go:123 +0x12b git.sr.ht/~rockorager/tcell-term.(*Terminal).run.func1() git.sr.ht/~rockorager/tcell-term@v0.1.0/terminal.go:117 +0x9d created by git.sr.ht/~rockorager/tcell-term.(*Terminal).run git.sr.ht/~rockorager/tcell-term@v0.1.0/terminal.go:104 +0x110 Don't invalidate on EventWidgetContent.
