OS X - Can we switch the Mix binaries to be Debug? #546

Closed bobsummerwill closed 8 years ago

bobsummerwill commented 8 years ago

As a workaround for the Heisenbug, can we switch the OS X Mix binaries to be Debug?

See https://gitter.im/ethereum/cpp-ethereum-development?at=574f4d816bbc2d1d4df0560a

bobsummerwill commented 8 years ago

Adding @ktorn, @SorenPeterson and @sussegaduss, all of whom are currently hindered by the broken El Capitan Mix binaries, and can then verify this workaround.

SorenPeterson commented 8 years ago

Sorry, but I don't quite understand what the workaround is. Will you explain it to me?

bobsummerwill commented 8 years ago

The workaround is something which I still need to do, and which this issue is tracking.

My workaround will be to switch our automation to use Debug configuration for our Mix.app file in the DMG, because that doesn't hit the Heisenbug.

I will be working on that today and will let you guys know when there is a DMG for you to try :-)

Sorry for the lack of clarity, @SorenPeterson!

bobsummerwill commented 8 years ago

Could you guys try this DMG, please? Thanks!

Or, for Yosemite ...

Or better yet:

sussegaduss commented 8 years ago

Hi all..

im not being able to download.. it downloads 2mb and then the connection get lost! None of the links above works. All gets the same error. Can you verify this?

bobsummerwill commented 8 years ago

Nope - all 4 are working for me right now. Are you in a remote area? Is your network usually reliable?

sussegaduss commented 8 years ago

Downloaded and still getting the same error... before it opens i get "quit unexpectedly" again...

ktorn commented 8 years ago

I successfully downloaded both El Capitan DMGs, but on both occasions Mix still crashes on startup with the same error. Currently building from source with cmake -DCMAKE_BUILD_TYPE=Debug as you suggested in #562, but I guess it will run into the same issue (assuming that's what you did with the above DMGs).

bobsummerwill commented 8 years ago

Bah! I see the issue now. Sorry, guys.

There are multiple branches with very similar looking code, and the fix was in the wrong place.

Around the loop again. Stay tuned, and I will give you a heads up when the DMGs are refreshed.

bobsummerwill commented 8 years ago

OK - these interim ones are ready again now ...

Sorry to report that it still crashes.

The crash log shows that the thread number changed from 7 to 9 but it is still the same thread name QThread and still on the same call of the thread stack: dev::eth::PathGasMeter::handleQueueItem()

bobsummerwill commented 8 years ago

Ugh. Bloody Heisenbug. Thanks for testing, @ktorn.

CC @VoR0220, @chriseth.

I have switched the OS X binaries to Debug, but we're still not happy. So I will close this issue, and add the people from this thread onto the Heisenbug issue.

SorenPeterson commented 8 years ago

It doesn't help everyone else... But that link (https://builds.ethereum.org/cpp-binaries-data/develop/cpp-ethereum-osx-elcapitan.dmg) worked for me. Thanks so much.

bobsummerwill commented 8 years ago

Thanks for that follow-up, @SorenPeterson.

Please could you try again, @ktorn, with that "final location" DMG? It should work :-)

ktorn commented 8 years ago

Unfortunately it doesn't work for me. Still crashes.

bobsummerwill commented 8 years ago

@ktorn Please can you do a brew update and brew upgrade, please? You might be out-of-sync on those other packages compared to us.

ktorn commented 8 years ago

brew update and brew upgrade all done. brew doctor reports no warnings. Latest DMG still crashes, on 2 machines with El Capitan. In the mean time I'm resorting to running it under Ubuntu in a VBox VM.

bobsummerwill commented 8 years ago

Alrighty ... sorry our voodoo magic didn't work for you, @ktorn.

We've just got to find this Heisenbug and kill it!
