Sorry, couldn't reproduce it on 10.12 VM with Go 1.9.2.
The crash happens in the main UI loop. I wonder if this happens every time? And, does it happen to other apps, e.g. todo app example? Will it crash if you click buttons instead of a text view?

from webview.

It is happens every time, very repeatable. I have tried a lot of other stuff like buttons, dialogs etc and everything else works, but when I just click inside a textbox and I see it gets focused (blue glow around the text box) it crashes immediately, every time.

It seems like it always crashes at the same line. (I did a git pull now so it is crashing on a different line compared to the first report)

I also tried the todo-go app, and it actually crashes as soon as the window shows up, printout at the bottom.

The window-go app (when clicking inside the text window):

@ooZberg Thanks for providing the details so quickly. I will have a look. Meanwhile, I have a few more questions:

  • Does this happen to C or C++ apps? (e.g. minimal example or timer-cxx example) Or does it only happen to Go apps?
  • What terminal do you use? Does it make any difference if you make it an app bundle (e.g.
    Todo.app/Contents/MacOS/todo directory structure, and then do open Todo.app from terminal, or just click on Todo app in the Finder). Normally, GUI apps are not supposed to be run from the terminal, so it might be the cause.
  • May I ask you to put some NSLog around each line in webview_loop - https://github.com/zserge/webview/blob/master/webview.h#L1607 to see where exactly it crashes?

from webview.

ooZberg avatar ooZberg commented on May 13, 2024

I have compiled minimal and timer-cxx examples and they booth work as expected.

  • The minimal example contains a text input (wikipedia search) and it works as expected

I am using the default Terminal.app

  • The apps both work with open minimal.app as well as with ./minimal.app/Contents/MacOS/minimal
  • When using open .app the app is running in non-Retina mode, and if i execute the binary itself it runs in Retina mode, but it does not seem to affect the crashes.

I am not sure how to add the NSLog commands, could you provide a modified webview_loop method and I can just replace it.

If I try to compile the example:

package main

import "github.com/zserge/webview"

func main() {
	// Open wikipedia in a 800x600 resizable window
	webview.Open("Minimal webview example",
		"https://en.m.wikipedia.org/wiki/Main_Page", 800, 600, true)
}

It crashes when I click the search window. (This worked fine in the minimal c application)

Ok. Looks like the crash happens somewhere in the cgo glue code. I don't think NSLog would help here. May I ask you to run the app with lldb? E.g. lldb ./window-go, then once the debugger loads - type r (for "run") and press enter. The app should crash as usually and leave a more detailed stack trace.

I have tried to run the window-go app with lldb

It does not seem to produce to much information though..

I have upgrade to macOS 10.13.2 and the same binary that crashed before does not crash anymore.🍺

Probably a bug in macOS itself? I suppose you could close this issue.
