shiny timeout when running locally? #1967

Open vnijs opened 6 years ago

vnijs commented 6 years ago

I've had this happen a few times when running a shiny app on my laptop with the latest version of shiny from GitHub. After sitting idle for a while it timesout. I can see that happening on a server but when running locally? Traceback reported below:

 Error in execCallbacks(timeoutSecs) :

Hi @vnijs, are you still seeing this? If so, can you try updating later to the latest CRAN version, if you haven't already?

jcheng5 commented 6 years ago

Oh, and httpuv from GitHub master as well. Thanks.

vnijs commented 6 years ago

Yep. Just happened again 2 days ago. Not sure how to reproduce though as it happens infrequently. I'm pretty sure I was already using the latest later but will install just in case. If I see it again I'll let you know @jcheng5

FYI Happened once today and once yesterday. App was just open in the back ground then just timed-out when running locally.

I wonder if it may be related to https://github.com/rstudio/shiny/issues/2033

Thanks. @wch I'm thinking I should add some proper error logging around the timedwait? I can do that today.

wch commented 6 years ago

I was just looking at this. A basic start would be to add the following code here:

  if (ret == EINVAL) fprintf(stderr, "cnd_timewait: EINVAL\n");
  if (ret == EPERM)  fprintf(stderr, "cnd_timewait: EPERM\n");

But I suspect we'll need even more info, like the values of _c, _m, and ts here.

I wish we we were able to consistently reproduce the error -- then we could run R with a debugger and put breakpoints in those locations.

jcheng5 commented 6 years ago

@vnijs Can you install_github("r-lib/later")? That'll at least print the error code next time. Thanks.

vnijs commented 6 years ago

No problem. It just happened again (running in Rstudio Window). Hadn't touched the app for a few minutes before the timeout. The output and stacktrace is shown below. Let me know if there is anything else you need.

Same return value (22) but (slightly) different messages in Rstudio Window JS console

pthread_cond_timedwait returned 22
Error in execCallbacks(timeoutSecs) : 
  Condition variable failed to timedwait
Stopped Radiant

@vnijs We're trying to reproduce the problem. Do you know if you need to interact with the application for it to crash, and if so, do you know what interactions are needed?

vnijs commented 6 years ago

Not that I have been able to determine. I open the app (e.g., https://github.com/radiant-rstats/radiant.data) in an Rstudio Window and then after some time (could be 10 min, an hour, or multiple hours) it might suddenly time out when I'm not using it. It is possible it is related to actions that happened > 10 minutes before but I have no way to know that.

The only thing I can think of that might be (indirectly) related is #2033, i.e., if you clicked the refresh actionLink at some point before (see screen shot below) or if you loaded a state file (e.g., download example and load through Data > Manage with Load data of type set to radiant state file). It certainly doesn't happen right away but maybe if you let it sit a while.

Sorry I don't have anything more specific. It is an odd one. Any way to build in more diagnostics that I could share if (when) it happens again?

Load state file:

wch commented 6 years ago

I think it's very unlikely that it has to do with #2033 - this is happening at a very low level in code that is related to the event loop from the later package.

Could you try installing this branch of later, and do your work as normal? When it hits the error, it will log some information which will help us find out what's going on:

devtools::install_github('r-lib/later@joe/timedwait-logging')

vnijs commented 6 years ago

Will do. Thanks @wch. In case it is relevant ... I see the following message when installing that branch

clang-4.0: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]

wch commented 6 years ago

@vnijs The fix for later has been merged into master.

As for the -pthread issue, that is a harmless one. More info at r-lib/later#11.

vnijs commented 6 years ago

Excellent! Thanks @jcheng5 and @wch

jcheng5 commented 6 years ago

later 0.7.2 is on CRAN now. Thanks @vnijs, we really dodged a bullet!

vnijs commented 6 years ago

No problem @jcheng5

I'm concerned there might be a new (related) issue. I posted to rstudio/rstudio but just now realized that run_now is listed in the traceback. This is with the latest later from GitHub. See below.

On macOS, (almost) every time I use radiant::radiant_window() and then close the Rstudio Window I see the execCallbacks(timeoutSecs) error below. Doesn't seem to happen on Windows.

Install using:

install.packages("radiant", repos = "https://radiant-rstats.github.io/minicran/")

> radiant:::radiant_window()

Starting radiant in an Rstudio window ...

Use radiant::radiant() to open radiant in the default browser or radiant::radiant_viewer() in Rstudio to open radiant in the Rstudio viewer

vnijs commented 6 years ago

Just tried closing the window before the Rstudio Window has fully loaded the app. R(studio) segfaults on both my Macs

wch commented 6 years ago

I was able to reproduce this occasionally in RStudio, and after several tries, once in the console. Note that after closing the window, I had to press Ctrl-C before it segfaulted.

$ R -e "radiant:::radiant_window()"
> radiant:::radiant_window()

Starting radiant in the default browser ...

Use radiant::radiant_viewer() in Rstudio to open radiant in the Rstudio viewer
or radiant::radiant_window() in Rstudio to open radiant in an Rstudio window

After many tries, I was able to get the error to happen when running R under lldb. The problem appears to be in httpuv:

After several more tries, I was also able to get this error:

Error in execCallbacks(timeoutSecs) : c++ exception (unknown reason)
Calls: <Anonymous> ... serviceApp -> service -> run_now -> execCallbacks -> .Call

@vnijs We have a potential fix for segfault issue. Can you try installing this version of httpuv?

devtools::install_github('rstudio/httpuv@fix-httprequest-close')

vnijs commented 6 years ago

Yes! Thanks @wch. FYI I was still able to get execCallbacks(timeoutSecs) to pop up once in about 20 tries but no segfaults. I was really hoping this was going to address #2033 as well but you no such luck :) You were right ... unrelated.
