Could you try it with the Espeak Synth selected instead of the microsoft one? I'm sure I've seen this before somewhere, but not in the software you mention.
Sure, here's the crash with all profile synths set to Espeak. It's pretty reliably triggered with the Rust-analyzer extension running. I set out to get this report, and it took about 10 minutes with a couple small Rust projects open. Not sure what's special about this extension other than that Rust is a bit of a beast to compile, but my system is pretty beefy.
Let me know if I can provide anything else. This is unfortunately a bit of a painful issue for me to keep hitting, so happy to help track it down any way I can. Thanks.

@ndarilek please also test this try build, as portable copy. https://ci.appveyor.com/api/buildjobs/csyh1ku00rkkpaut/artifacts/output%2Fnvda_snapshot_pr11437-20648%2C5707e0e4.exe
Please enable "process only MSAA and IA2 events" in the advanced settings on this NVDA try build. Is this issue then still reproducible?
Hmm, seems so many VS Code issues are coming up eventually, I.E:
And this too.
Was away for the weekend and taking today off, but I'm now running the portable build with the settings tweak in place. Tomorrow I'll put it through its paces and report back.
Thanks.

Is there any value in me trying to duplicate this at this juncture? if so, I'll do so in the next week or so. I'm not sure if this is in the "we only have one user" limbo or not but I'll want Rust working at some point as well, and if this is widespread it seems like kind of a big deal.
Because there has been some work in this area recently it would be helpful to have a fresh log with a recent alpha build. Please include the build number with the log.
So the Rust Analyzer thing may be a red herring. I'm hitting this just editing some Powershell and YAML files now.

What happens in the log after this? What was the behavior of NVDA? It looks like changing config profiles was taking too long. Can you try starting nvda with a different config directory (temporarily) to ensure this isn't config specific? To do so:
nvda -c %temp%/tempNVDAconfig/
Note, NVDA will run with a fresh, default config, but your normal config will not be affected. Running NVDA as usual will return to your standard config.
I had some pretty awful luck running the alphas, so apologies for not getting updated logs.
However, I upgraded to 2020.3, and it does seem a lot more stable, even above and beyond the RCs which also behaved badly for me. I've got a couple larger Rust projects open and things seem fine now.
I don't know what happened, and am literally knocking on wood, doing anything I can to not return to the days of restarting NVDA every couple minutes. :) If I make it to the weekend with no crashes, I'll come back and close this.
Please add your current vs code version number so we have a record. If problems occur again, it will help us to confirm what has changed.
Unfortunately it's still here, and has nothing to do with Rust Analyzer. Hit it in VSCode over an SSH connection. I had to do a repair installation of Windows this morning, and just applied the H2 update, so I'm probably pristine. NVDA 20202.3:

That's where the log ends. After 30 seconds or so of inactivity I restart NVDA.
This seems to be caused by a deadlock in nvwave
the main thread blocked waiting on _idleUnbuffered
, meanwhile thread 3128 (Dummy-82)
is waiting in a blocking call waiting for audio data to be finished playing. The question is now, why is the playing of the audio blocked.
Given that the main thread is trying to stop the synthesizer, perhaps there is another way to break the deadlock and cancel the waitForSingleObject
call.
This is just a hunch, but are you set to indicate indentation with tones?
Also, iirc you were having trouble with your bluetooth audio device and needed to get something playing silent audio. Any chance this is audio device specific? I could see indentation with tones + weird audio device = weirder bugs.
But I don't know the code, so maybe I'm entirely off base.
I am using tones. The audio device is standard and shouldn't be an issue--the problem I had was after the card, in the sound bar itself.
I'll disable tones and report back any changes next week. I'm also using beeps for capitalization, so maybe there's some weird interaction between tone generation, One Core voices and something VSCode/Electron is doing.
Still happening. Only editing HTML and Hugo templates today, so no Rust in sight. I wouldn't know to blame VSCode if this didn't happen all last weekend, when I never worked with VSCode, and today when I did. :(
Looking at the stacks for the different threads, I think this can be blamed on a deadlock between threads, likely specific to onecore. I doubt it is related to VS Code at all. I'm going to mutate this issue to make it more generic. If the problem still occurs after we fix this deadlock I think it would be best to open a new issue.

Not sure if this is useful data or just noise, but figured I'd include it anyway.
In addition to the VSCode freeze, I'd experience an almost daily slowdown of my system, to the point where the only remedy was to hard reset. I couldn't narrow it down to any specific behavior on my end, nor did anything seem to reliably fix it. Sometimes killing Firefox or VSCode would do it, others not. Debugging the issue was made significantly more difficult by me not being able to use my system to do said debugging.
Out of desperation, I've switched all of my config profiles to use Espeak. The daily slowdowns are gone, and have been for the past few days.
There are still occasional VSCode freezes, and I'm working to get a log. But it does seem like there should be some major performance profiling work done around the One Core TTS code. If anyone has tips on how to recover a system so bogged down that NVDA can't even be restarted reliably, and where restarting it doesn't seem to always get performance back, I'm willing to wade back into that mess and try getting more useful data. :)
@ndarilek I want to keep this issue focused on Freeze. The slow down you are describing should be created as a new issue, however you'll need to dig a little deeper on the investigation side. You may wish to discuss this on the mailing lists to get some ides on how to investigate. I'm going to mark these comments as off-topic.
Hi @ndarilek, I have been looking into this. I don't have a water tight theory on how this is happening, but I have attempted to cover some possible causes. Could you please test the following "try" build (based of a very recent 'alpha' build) and let us know if you encounter any freezes?
Been using this in VSCode with OneCore voices for the past few hours, and haven't had to restart once. I'll report back if that changes, but so far so good! Thanks!
What was the issue?
It's hard to know for sure, there are three (quite technical) things I did to improve the robustness of this. I suspect a driver on your machine is not behaving how we expect. Or we are relying on some behavior that is common but not guaranteed. For the details take a look at #11886
This should be fixed with the merging of PR #11886, and will be include in 2020.4
BTW, this bug is still present in 2021.2 Beta. Not nearly as frequent, but still happens. Sometimes it happens after a few minutes of use, sometimes I get a full day.
Should I open a new issue, or just post updated logs here when it happens? The new issue would be mostly identical, except for not calling out VS Code specifically since the lockups happen everywhere. The logs look pretty similar--watchdog threads freezing plus assorted stacktraces.
Thanks.

Opening a new issue with the logs and crash dumps would be great.
