* ui: fix deadlocks in message channelRobin Jarry2023-05-203-42/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several ways the ui message channel can fill up leading to deadlocks. 1) Invalidate() changes the value of uiState to DIRTY. The following call sequence: QueueRedraw() Invalidate() QueueRedraw() Leads to multiple nil messages being queued in the message channel whereas one could assume that the second QueueRedraw() would do nothing. This is caused by the tri-state nature of uiState. 2) We use the same channel to convey state change, keyboard events and redraw requests. Since a keyboard event almost always triggers a redraw, we end up trying to append a redraw message in the same goroutine that reads from the channel. This triggers a deadlock when there are more than 50 pending messages. Solve the issue by using multiple channels, one per type of message that needs to be sent to the main ui thread. Remove QueueRedraw() and merge its functionality in Invalidate(). Only use a DIRTY/CLEAN state to determine if something needs to be queued in the redraw channel. Use a channel for quitting instead of an atomic. Restructure some code functions to have a cleaner API. Use a for loop in the main thread and select from all channels.

* textinput: improve stemmingKoni Marti2023-05-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | Fix cursor index after stemming and reset it to the position where the completion should occur. Only stem to add more information and not remove any user input. Stemming is activated on the textinput line when the user presses the Tab key. The idea of stemming is to adjust the textinput line to the common ground (="the stem") of the completions options. When the stemmed input line is set, however, the cursor will be moved to the end of the line if there is a text part on the right side of the cursor where the completion should occur. Another Tab press will activate the onStem function again, which then removes the right part of the text input leading to the loss of the user input. This can be prevented by moving the cursor to the place of the completion after stemming. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
* ui: avoid races with queue redrawRobin Jarry2023-04-271-15/+11
| | | | | | | | | | | | | | | | | | When calling ui.QueueRedraw() and a redraw is currently in progress, the redraw int value still holds REDRAW_PENDING since it is updated once the redraw is finished. This can lead to incomplete screen redraws on the embedded terminal. Even changing the redraw value before starting to redraw is exposed to races. Use a single atomic int to represent the state of the UI so that there cannot be any confusion. Rename the constants to make them less confusing.

| | | | | | | | | | | | | | | | Another attempt at fixing the high CPU usage when terminal tabs are running interactive tui applications and the message list tab is selected. There are cases where a terminal widget can be visible but not focused (composer, message viewer, attachment selector, etc.). Define a new Visible interface with a single Show() method.

* textinput: fix crash when scrolling back in command historyRobin Jarry2023-01-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pressing up while in command mode, calls TextInput.Set() with the previous command in the history. If the command exceeds the current terminal width, there is a scroll mechanism that puts the cursor at the end of the text (see ensureScroll()). However, the offset used to perform the draw is not the current scroll value but the "previous" one. When the one before last command required a longer scroll offset than the current command length, this causes a crash: Error: runtime error: slice bounds out of range [348:5] git.sr.ht/~rjarry/aerc/lib/ui.(*TextInput).Draw(0xc0017ce000, 0xc005460570) git.sr.ht/~rjarry/aerc/lib/ui/textinput.go:111 +0x525 git.sr.ht/~rjarry/aerc/widgets.(*ExLine).Draw(0x30?, 0xc01de13b08?) git.sr.ht/~rjarry/aerc/widgets/exline.go:76 +0x1d git.sr.ht/~rjarry/aerc/lib/ui.(*Stack).Draw(0xc0003f0ff0?, 0x0?) git.sr.ht/~rjarry/aerc/lib/ui/stack.go:30 +0x49 git.sr.ht/~rjarry/aerc/lib/ui.(*Grid).Draw(0xc00038c240, 0xc0003f0ff0) git.sr.ht/~rjarry/aerc/lib/ui/grid.go:126 +0x225 git.sr.ht/~rjarry/aerc/widgets.(*Aerc).Draw(0xc0003f4000, 0xc0003f0ff0) git.sr.ht/~rjarry/aerc/widgets/aerc.go:176 +0x1d2 git.sr.ht/~rjarry/aerc/lib/ui.(*UI).Render(0xc0003a0000) git.sr.ht/~rjarry/aerc/lib/ui/ui.go:110 +0x63 main.main() git.sr.ht/~rjarry/aerc/aerc.go:255 +0x9c5 There are actually two distinct issues here: 1) The scroll offset used for drawing must be the current one, not the one from the previous ensureScoll() call. 2) The scroll offset must be reset when changing the text with TextInput.Set(). Other methods that change the text actually call ensureScroll but they make incremental changes to the text, since Set completely overwrites everything, it makes more sense to set the scroll offset to 0.

* config: make various sections accessible via global varsRobin Jarry2022-12-141-2/+2
| | | | | | | | | | | | | | | | | | | | There is only one instance of AercConfig which is associated to the Aerc widget. Everywhere we need to access configuration options, we need somehow to get a reference either to the Aerc widget or to a pointer to the AercConfig instance. This makes the code cluttered. Remove the AercConfig structure and every place where it is referenced. Instead, declare global variables for every configuration section and access them directly from the `config` module. Since bindings and ui sections can be "contextual" (i.e. per account, per folder or per subject), leave most local references intact. Replacing them with config.{Ui,Binds}.For{Account,Folder,Subject} would make this patch even more unreadable. This is something that may be addressed in the future.

* invalidatable: always mark ui as dirty OnInvalidateTim Culverhouse2022-10-072-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | The Invalidatable struct is designed so that a widget can have a callback function ran when it is Invalidated. This is used to cascade up the widget tree, marking things as Invalid along the way so that only Invalid widgets are drawn. However, this is only implemented at the grid cell level for checks if the cell is invalidated -- and the grid cells are never set back to a "valid" state. The effect of this is that no matter what is invalidated, the entire UI gets drawn again. The calling through the Invalidate callbacks creates *several* race conditions, as Invalidate is called from several different goroutines, and many widgets call invalidate on their parent or children. Tcell has optimizations to only rerender screen cells that have changed their rune and style. The only performance penalty by redrawing the entire screen for aerc is the operations *within the aerc draw methods*. Most of these are not expensive and have relatively no impact on performance. Skip all of the OnInvalidates, and directly invalidate the UI when DoInvalidate is called by a widget. This reduces data races, and simplifies the widget redraw logic signficantly.

* completion: install panic handler in completion callbackRobin Jarry2022-03-251-0/+2
| | | | | | | | | This callback is actually invoked in a goroutine by time.AfterFunc. The panic handler must be explicitly installed.

* logging: added a log on panicMoritz Poldrack2022-03-231-0/+3
| | | | | | | | | | | | | Since panics still regularly "destroy" the terminal, it is hard to get a stack trace for panics you do not anticipate. This commit adds a panic handler that automatically creates a logfile inside the current working directory. It has to be added to every goroutine that is started and will repair the terminal on a panic. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>
