NOTE: This is different from, but may be related to, #2230

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.175]
Windows Terminal version: 0.3.2142.0

Steps to reproduce

  1. Open a new Windows Terminal instance
  2. Open a second tab using either the "+" button
  3. Close the new tab using CTRL+W, middle clicking the tab, or clicking the tab's "x"

Repeat steps 2-3 as fast as possible.

Expected behavior

Tabs continue to open and close.

Actual behavior

PowerShell - Most of the time, WT stops responding and interacting with it shows the "WindowsTerminal.exe is not responding" modal

CMD / WSL - WT stops responding for about 1 second and then exits (also happens for PowerShell sometimes)

Yea this is pretty trivially repro-able. I got it with a quick click on the new tab followed by immediately middle clicking. Thanks for the report!

I'm getting the same issues without middle-click - for me it it becomes unresponsive when I open WindowsTerminal and click the dropdown menu to open a Command Prompt-style tab, then close the Powershell tab fairly quickly.

I managed to repro this with a debugger attached and it's the blocked at the same point as #2433 (_hJob.Reset() in ConhostConnection::Close()), so resolve the underlying issue should fix both issues.

(when someone tackles this, can they explain to me the purpose of _hJob? It doesn't appear to be used anywhere except to reset it, and I didn't think that operation blocked.)

I’m surprised that it’s still there, actually. We removed most (?) of it with a recent pull request.

It existed to make sure the console host was torn down (hard!) when a tab was closed, but that was causing powershell to crash because its console was torn down. If we aren’t initializing the job object, it’s not doing anything on reset. The hang could be on the line above it, though, especially if that line is a WaitForSingleObject.

Thanks for the summary. You're right, I can comment out that line and still repro the hang so it must be the line above: WaitForSingleObject(_piConhost.hProcess, INFINITE)

I can confirm that it still exists on latest release with Windows 10 Build 18362.

This still reproduces in 0.4.2382.0, so I'm guessing it's unrelated to #2198

I now reproduce it by rapidly splitting and closing panes using keyboard bindings (split x 3, close x 3, repeat).

Playing with this for a few minutes, I got a crash here:

Apparently updating the scrollbar? I'll try debugging with a actual Debug build next so I can get more details

@xobs commented on GitHub (Sep 18, 2019):

I see different behavior -- it's closing itself when using the interface (e.g. using wget), not when exiting a terminal.

Note that processes continue to run after Terminal has closed, sometimes for weeks at a time. I have a gtkwave session that's been running for three weeks after its original Terminal closed itself.

This is still an issue on the latest release, middle clicking to quickly close tabs makes the entire terminal app crash

@utybo yep, hence why the issue is still open. We'll close the issue once a fix has been found and a PR with that fix has been merged 😜

From @Treit in #2947

Environment

Windows build number: 10.0.18975.0
Windows Terminal version: 0.5.2622.0

Steps to reproduce

1. Run wt.exe to start an instance of Windows Terminal

2. Press Ctrl-t 4 or 5 times to open a few tabs (running PowerShell)

3. In each tab, run `dir c:\ -rec`

4. Wait a few seconds, then click the 'x' on one of the tabs to close it while it is writing text to the console

Expected behavior

The tab closes.

Actual behavior

The terminal crashes with an Access Violation due to a null pointer dereference in TerminalControl!winrt::impl::consume_Windows_UI_Xaml_Controls_Primitives_IRangeBase<winrt::Windows::UI::Xaml::Controls::Primitives::ScrollBar>::Maximum

Notes

I can reproduce this consistently. Let me know if you would like a memory dump.
