Komodo IDE 10.2.1 on macOS 10.12.4 hanging

[pemcg]

Short Summary

I'm running Komodo IDE 10.2.1 on MacOS 10.12.4. I haven't used Komodo for a while so I'm not sure if the issues are related to the 10.12.4 upgrade that I did this morning, but I've had 2 cases today of Komodo hanging (infinite beachball). I've also noticed generally that the UI is frustratingly slow scrolling up and down, it's not a smooth experience at all.

Both of the hangs have been with about 5-6 files open, relatively small files (<400 lines)

Note From Developer - Please Read

A nightly is now available with a fix for this hang, you can download it here:

http://downloads.activestate.com/Komodo/nightly/komodoide/latest-10.2.x/

If you are still experiencing this issue with the latest build please supply a backtrace of Komodo in this ticket (when it is hanging).

To get the backtrace take the following steps:

• Open your terminal
• Run the following command:

  kill -s SIGABRT $(ps aux | grep komodo | grep -v codeintel | grep -v grep | awk '{print $2}')

• You should get a crash reporter dialog, please enter your email and in the comment enter: issue #2424

Additional Information

Attached is the text of the "Report the problem to Apple" output when I did a force quit. komodo_hang.txt

Can you reproduce this using Help > Troubleshooting > Restart in Safe-mode ?

Please verify that when restarting in safe-mode Komodo should be using the default UI (all your settings would be temporarily reset).

[pemcg]

I've restarted in safe mode and I'll try using again tomorrow (it's evening here now).

Thanks

[pemcg]

It still happens in safe mode. In this case I'd just added some text to a file, and clicked the 'Tools' menu. Immediately on clicking 'Tools' I got the spinning beachball.

[pemcg]

and annoyingly I've lost all of my edits when I restart

[tuckdesign]

This is connected to osx 10.12.4 update. I have same experience. It was working fine, yesterday I updated OSX to 10.12.4 and now it has crashes (really similar to #1007 ): I work in IDE, then click on browser (FF) window, browse shortly, when I click back on IDE winow it is frozen (just loader icon and need to 'Force quit' Komodo). But as in #1007 it does not happen every time.

[tuckdesign]

Ran it and attached to lldb. When it hangs stopped process and each time I get backtrace liket this: https://pastebin.com/YdeSufwf

[Naatan]

Oh good another freeze due to an OSX update, is Apple actively trying to discourage non-native apps?

Thanks for the backtrace @tuckdesign, we'll investigate.

[Naatan]

Anything consistent in the error log when this hang happens?

Also, more backtraces would be tremendously helpful, so we can determine wheter they offer us the insight we need or if it's just noise.

[Naatan]

Looks related:

[Naatan]

@tuckdesign and @pemcg - can you guys reproduce the issue with Safe-mode? Help > Troubleshooting Restart in Safe-mode.

I'm on OSX 10.12.4 but so far have not been able to reproduce.

[pemcg]

@Naatan yes, also hangs in safe mode

[Naatan]

thanks @pemcg

Is the issue easily reproducible for you? ie as simple as switching back and forth between apps? Or is it very random and hard to consistently reproduce?

[tuckdesign]

It's random but quite often. Most often when I have open few php/js files that I am editing, then switch to browser window, browse shortly and then click back on komodo window. Not sure is it better with cmd+tab to switch windows (trying that now).

[Naatan]

Does disabling app nap work around the issue?

defaults write NSGlobalDomain NSAppSleepDisabled -bool YES

You can revert it with

defaults delete NSGlobalDomain NSAppSleepDisabled

[tuckdesign]

Checked that with defaults read (and it is in komodo's plist also). It is already set to yes.

[Naatan]

Bah alright.

Anything else you can give me to reproduce the issue? Given the backtrace we feel it may be related to a text input field of some sort, what do you have focussed in Komodo when the hang happens? Plus any other contextual information that might be relevant?

Still have not been able to reproduce the issue on my end.

[pemcg]

It's intermittent and not reproducible for me, but seems to be related to input from keyboard or mouse (i.e. not 'spontaneous' like the 10.0 crashes were)

It's happened after I've had several files open, have been inputting text into one tab/file, then click on another file's tab. Today it hung when I clicked on the 'Tools' menu, and another time when I just scrolled up with the mouse immediately after opening the file. It's hung twice each day, but I'm not a power/continuous user.

[Naatan]

@pemcg so in your case it hangs during regular use, not when switching to Komodo?

[pemcg]

@Naatan That's correct, it's only hung while actively being used, typing, clicking or mouse scrolling.

[tuckdesign]

Just had hang on mouse click. Had 3 tabs with js code. Clicked on tab to change tab and komodo is hanging: https://pastebin.com/vSyCyF0G Note: I was on browser window, clicked back to komodo and then when I tried to switch tab it was hanging.

[tuckdesign]

Can't share code I am working on with you, so selected to test on https://github.com/facebook/react Here is how you can reproduce:

1. Clone https://github.com/facebook/react from git
2. Create komodo project test.komodoproject in root folder of cloned repository and open it
3. Open 3 js files for editing, see screenshot to see which ones I opened: http://prnt.sc/eq9723
4. Put cursor somewhere in each of files (like you are editing - I didn't change/edit anything)
5. Quickly click on tabs to change from tab to tab until komodo hangs You can see on screenshot that it started hanging when I tried to switch from second to first tab. If you need, I can send you my KomodoIDE settings or anything you need from that folder

[Naatan]

@tuckdesign and this is 100% reproducible for you like this? Unfortunately I'm not able to reproduce, I tried it for about a minute or two, then tried holding ctrl+tab for just as long. No dice.

[Naatan]

Also, could anyone having this issue share their system specs?

[tuckdesign]

Hm, unfortunately not... doesn't happen now :(

For system specs np, let me know what you need.

[Naatan]

So, given the differences in the 2 lldb reports shared so far it seems likely that this issue is caused by macOS 10.12.4 and not Komodo itself, seeing as in both reports the Komodo specific code is wildly different.

If you feel adventurous enough you could attempt to see if the OSX 10.12.5 beta resolves the issue:

https://9to5mac.com/2017/03/28/macos-10-12-5-beta-1/

Unfortunately as we are unable to reproduce the issue internally we cannot attempt this ourselves.

[Naatan]

For system specs np, let me know what you need.

Primarily your system model, I want to see if there's correlation to newer hardware.

[dch]

hey folks I am seeing these symptoms here too. Only since last update to OSX (this week) and Komodo (the same day yesterday). 100% repeatable about hourly, every time I alt-tab away and back again (2 monitor setup).

I also suspect an OSX bug BTW, as I have had hangs with other applications, unable to alt-tab "back" -- iterm2, firefox, komodo, all go pants down the same way.

@Naatan good news is that I have komodo working on FreeBSD so your revenue stream is still safe ;-)

[Naatan]

I also suspect an OSX bug BTW, as I have had hangs with other applications, unable to alt-tab "back" -- iterm2, firefox, komodo, all go pants down the same way.

That's very telling, sounds like Apple has some fixing to do. Have you considered trying the 10.12.5 beta?

[mrochford]

Adding Apple Dump. I am seeing the same issue that is being described.

10.12.4_komodo_dump.txt

[mitchell-as]

Thanks for the additional info. There is nothing in that dump that indicates a Komodo problem. All active threads appear to be hanging in the OSX kernel or system libraries.

[mrochford]

I have since downloaded and installed the 10.12.4 combo update. I found other application that were experiencing these same symptoms were pointing their users to manually run the update as it will replace any corrupt/missing files.

After running the update I have not been able to recreate the issue within Komodo.

[mitchell-as]

@mrochford Thank you for taking the time to write up your "fix" for this. We really appreciate it.

[Naatan]

Very nice @mrochford, how long have you gone without a freeze so far? Sounds like we might be able to close this one.

[tuckdesign]

Unfortunately installing combo update didn't help on my side :(

[Naatan]

@tuckdesign consider tring the 10.12.5 beta. From all appearances this isn't something we can fix on our end.

[tuckdesign]

Yes, that's clear it is osx bug (happens sometimes with email app and firefox also), but trying beta version won't guarantee things will work ok (might even cause more problems, it is beta) and it's hard to revert back after that, so, we'll have to wait for apple...

[mrochford]

In the last 24hrs Komodo has only "froze"/"spinning wheel" once since doing the 10.12.4 combo update. This has not entirely fixed all application on my system though. As others have outlined in this thread, this issue has nothing to do with Komodo and everything to do with the latest update pushed by Apple.

To resolve this today I think people have two solutions:

1. Install the combo update and cross your fingers it solves the issue.
2. If you have backups, restore your machine back to 10.12.3 and wait for further updates from Apple before going to something greater then 10.12.3.

My 2cents.

[Naatan]

I would add a third cross your fingers solution; try the 10.12.5 beta.

[clokep]

@Naatan asked me to upload a stack trace over IRC, here it is. Note that I actually had two running Komodo IDE processes:

~ ps -A | grep Komodo
82539 ??        69:23.14 /Applications/Komodo IDE 10.app/Contents/MacOS/komodo
82542 ??         1:16.69 /Applications/Komodo IDE 10.app/Contents/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -O /Applications/Komodo IDE 10.app/Contents/SharedSupport/codeintel/oop-driver.py --import-path /Applications/Komodo IDE 10.app/Contents/Resources/python/komodo --database-dir /Users/pcloke/Library/Application Support/KomodoIDE/10.2/codeintel --connect pipe:/var/folders/ml/0nnlgt2s1t3gp8vkrl6t51500000gn/T/komodo-codeintel-pOVZcw-oop-pipes --log-file stderr

There's a stack trace for both attached.

thread-backtrace.txt

[Defman21]

The second one is codeintel :)

[twhiteman]

I'm another one hitting this hang issue on Mac OS X (randomly, a few times per day). I usually notice this when Alt-Tabbing back to Komodo, and find it completely unresponsive (e.g. it doesn't even display the Komodo window, it's like I never tried to switch to it). I've also hit this when using Komodo, most recent after saving a file (keyboard shortcut), Komodo became unresponsive (luckily it had saved the file though).

Mac OS 10.12.4, Komodo IDE 10.2.1

[Naatan]

@twhiteman have you tried the suggestions shared here? Ie. attempt the 10.12.5 beta or the 10.12.4 combo update?

Regrettable as this issue is it doesn't appear to be one we can fix on our end, the issue lies with macOS.

[pemcg]

I appreciate that the problem is with macOS, but Komodo is the only app that I see the problem with. Is it worth doing any investigation to determine what makes Komodo more vulnerable to these macOS bugs? Other cross-platform apps such as Sublime text work fine. It would be great if we could help Komodo protect itself from the OS.

[Naatan]

From what I'm hearing there are very mixed results, some people have multiple apps hanging, others just have Komodo hanging. The thing is the logs indicate the issue is not from any one single call in Komodo, many different calls can cause it.

What this ends up meaning is that even if it is something that macOS broke and we have to pay the price for fixing it then that would cost a significant effort to fix as there is unlikely to be a silver bullet solution to this problem. Likely it'll take an update of Mozilla and other components to fix. If we're lucky simply updating the OSX SDK to eg. 10.10 would work, but that would mean deprecating support for 10.9 (which honestly wouldn't be THAT bad). Either way it would be a significant effort and thus not something we could do for the 10.x series, or at least not easily.

For now the best we can do is await feedback of macOS 10.12.5 as it is not unlikely this would have a fix for the hanging issue. Seeing as we have yet to be able to reproduce the issue internally it is not something we can test ourselves. It's an unfortunate situation all around :\

[mrochford]

Ok it has been awhile since I have updated where I am at with this issue. As of today I am still seeing the "freezes"/"Spinning Wheel of death". I am going to take a new approach based on some other reading I have done where other applications have seen these issues.

1. Uninstall Komodo completely Directions can be found here.
2. Reboot
3. Download a fresh copy of Komodo
4. Install

I am doing this as a "hail mary pass" type fix. If it works awsome, if not ... sigh.

[twhiteman]

Update: Ignore paragraph below - I no longer believe 10.1.4 is immune to this issue.

I've reverted back to Komodo IDE 10.1.4 (last week) and have not had a hang since, so it might not be a Mac OS specific problem after all. http://downloads.activestate.com/Komodo/releases/

[mrochford]

I am running into the same issues with Komodo 10.1.4 as well :-(

[tuckdesign]

Right, 10.1.4 didn't help. @twhiteman Did you change something else also when switching to 10.1.4?
