I am experiencing a lot of random crashes with this VM on OSX 10.6. It just crashed again, and this time I cannot get it to restart. It seems to be crashing in a socket receive class. The stack trace is here :-

This is not a crash, it just quits to OS due to error at startup. To avoid imminent leave to OS, put an error handler around your startup code (i guess it is in CoreMQStompConnection somewhere?).

Hi, Is there a 1.3 OneClick build available with the Cog VM, or should I just down load the linux and OSX Cog builds from the Jenkins server?

The script on the hudson is old... we need to update it. And move everything from hudson to jenkins. And, and...

So for now:

       https://gforge.inria.fr/frs/download.php/28922/Pharo-1.3-OneClick.zip

hand-build one-click with Cog as build from https://ci.lille.inria.fr/pharo/view/Cog/

...

often run into problems with having different VMs/Plugin on different servers, and like the idea of having both Liux and OSX supported in one package, where I can just update the image.

an error caused by a primitive failure with invalid socket: SocketStream>>receiveData

Receiver: SocketStream[inbuf:4kb/outbuf:4kb] Arguments and temporary variables:

looks like your image was saved with socket being open and upon restart it tries to read data from it. This , of course , causing failure and leads to error signaled. If you want to track down the error, there is an option in system settings: 'Make a snapshot of new version before quit On unhandled exception, save a new version of image before quit' in 'Headless mode' group.

I am experiencing a lot of random crashes with this VM on OSX 10.6. It just crashed again, and this time I cannot get it to restart. It seems to be crashing in a socket receive class. The stack trace is here :-

This is not a crash, it just quits to OS due to error at startup. To avoid imminent leave to OS, put an error handler around your startup code (i guess it is in CoreMQStompConnection somewhere?).

Hi, Is there a 1.3 OneClick build available with the Cog VM, or should I just down load the linux and OSX Cog builds from the Jenkins server?

The script on the hudson is old... we need to update it. And move everything from hudson to jenkins. And, and...

So for now:

       https://gforge.inria.fr/frs/download.php/28922/Pharo-1.3-OneClick.zip

hand-build one-click with Cog as build from https://ci.lille.inria.fr/pharo/view/Cog/

...

often run into problems with having different VMs/Plugin on different servers, and like the idea of having both Liux and OSX supported in one package, where I can just update the image.

This is my code :- startAnnouncing        process notNil ifTrue: [ ^ self ].        process := [                [ [ [ self announceNextCommand ]                        on: ConnectionTimedOut                        do: [ :e | ] ] repeat ]                                on: Error                                do: [ :e | self logger error: 'Error in startAnnouncing e --> ', e greaseString.                                                self error: e.                                                e return

this code looking suspicious. but i not sure what it does, do you override #error: method in your class? what it does? if it not overridden, then by sending self error: you causing another error to be signaled, which is not handled by any handler block so, it will signal an unhandled error exception and finally bail out to OS during startup. To simplify things, what happens is following: [ self error: 'hahaha' ] fork. instead it should be like: [ [ self error: 'hahaha' ] on: Error do: [:ex | .. handle error here, and don't let it being unhandled ] ] fork.

                               ].                ] forkAt: Processor highIOPriority named: 'Juliet Stomp Announcer'

How can I make this safer, or make it in such a way that the image doesn't crash?

Also is the image destroyed now? Is there a way to start it and bypass this code? Thanks for looking into this.

This happened after a VM crash, when I try to restart I get this in the log. Isn't the error caused by the isEmptyOrNil primitive? Is there anyway for me to access the image now?

an error caused by a primitive failure with invalid socket:

looks like your image was saved with socket being open and upon restart it tries to read data from it. This , of course , causing failure and leads to error signaled.

If you want to track down the error, there is an option in system settings: 'Make a snapshot of new version before quit On unhandled exception, save a new version of image before quit' in 'Headless mode' group.

I am experiencing a lot of random crashes with this VM on OSX 10.6. It just crashed again, and this time I cannot get it to restart. It seems to be crashing in a socket receive class. The stack trace is here :-

This is not a crash, it just quits to OS due to error at startup. To avoid imminent leave to OS, put an error handler around your startup code (i guess it is in CoreMQStompConnection somewhere?).

Hi, Is there a 1.3 OneClick build available with the Cog VM, or should I just down load the linux and OSX Cog builds from the Jenkins server?

The script on the hudson is old... we need to update it. And move everything from hudson to jenkins. And, and...

So for now:

       https://gforge.inria.fr/frs/download.php/28922/Pharo-1.3-OneClick.zip

hand-build one-click with Cog as build from https://ci.lille.inria.fr/pharo/view/Cog/

...

often run into problems with having different VMs/Plugin on different servers, and like the idea of having both Liux and OSX supported in one package, where I can just update the image.

This code is used to keep a socket connection open to an ActiveMQ JMS server. I use the Stomp protocol to send messages from ST to various servers in my cluster via JMS. The self error: e code was just meant to fire up the debugger, so I could trace any errors. I'll remove that now.

So do I have to rebuild a new image from scratch now? Is there any command line switch that I can use to by pass the loading of my app on start up?

none. rebuild an image.

This is my code :- startAnnouncing        process notNil ifTrue: [ ^ self ].        process := [                [ [ [ self announceNextCommand ]                        on: ConnectionTimedOut                        do: [ :e | ] ] repeat ]                                on: Error                                do: [ :e | self logger error: 'Error in startAnnouncing e --> ', e greaseString.                                                self error: e.                                                e return

this code looking suspicious. but i not sure what it does, do you override #error: method in your class? what it does? if it not overridden, then by sending self error: you causing another error to be signaled, which is not handled by any handler block so, it will signal an unhandled error exception and finally bail out to OS during startup. To simplify things, what happens is following:

[ self error: 'hahaha' ] fork. instead it should be like:

[ [ self error: 'hahaha' ] on: Error do: [:ex | .. handle error here, and don't let it being unhandled ] ] fork.

...

                               ].                ] forkAt: Processor highIOPriority named: 'Juliet Stomp Announcer'

How can I make this safer, or make it in such a way that the image doesn't crash?

Also is the image destroyed now? Is there a way to start it and bypass this code? Thanks for looking into this.

This happened after a VM crash, when I try to restart I get this in the log. Isn't the error caused by the isEmptyOrNil primitive? Is there anyway for me to access the image now?

an error caused by a primitive failure with invalid socket:

SocketStream>>receiveData

...

...

       Receiver: SocketStream[inbuf:4kb/outbuf:4kb]        Arguments and temporary variables:

       Receiver's instance variables:                recentlyRead:   716                socket:         a Socket[invalidSocketHandle]                inBuffer:       'CONNECTED session:ID:John-Tooheys-MacBook-Pro.local-56368-1315585750...etc...                outBuffer:      'SUBSCRIBE destination: /topic/parspro-core.juliet-core-events

looks like your image was saved with socket being open and upon restart it tries to read data from it. This , of course , causing failure and leads to error signaled.

If you want to track down the error, there is an option in system settings: 'Make a snapshot of new version before quit On unhandled exception, save a new version of image before quit' in 'Headless mode' group.

I am experiencing a lot of random crashes with this VM on OSX 10.6. It just crashed again, and this time I cannot get it to restart. It seems to be crashing in a socket receive class. The stack trace is here :-

This is not a crash, it just quits to OS due to error at startup. To avoid imminent leave to OS, put an error handler around your startup code (i guess it is in CoreMQStompConnection somewhere?).

Hi, Is there a 1.3 OneClick build available with the Cog VM, or should I just down load the linux and OSX Cog builds from the Jenkins server?

The script on the hudson is old... we need to update it. And move everything from hudson to jenkins. And, and...

So for now:

       https://gforge.inria.fr/frs/download.php/28922/Pharo-1.3-OneClick.zip

hand-build one-click with Cog as build from https://ci.lille.inria.fr/pharo/view/Cog/

often run into problems with having different VMs/Plugin on different servers, and like the idea of having both Liux and OSX supported in one package, where I can just update the image.

The joys of ST :-( Pharo really needs some kind of safe mode, that you can boot into, to fix these kinds of problems. Thanks again for you help.

We are working on that. Did you see the fix in startup and all the work to make sure that you can work on headless mode ie not crashing your image because a pop up arise on a headless server... Stef

This code is used to keep a socket connection open to an ActiveMQ JMS server. I use the Stomp protocol to send messages from ST to various servers in my cluster via JMS. The self error: e code was just meant to fire up the debugger, so I could trace any errors. I'll remove that now.

So do I have to rebuild a new image from scratch now? Is there any command line switch that I can use to by pass the loading of my app on start up?

none. rebuild an image.

This is my code :- startAnnouncing process notNil ifTrue: [ ^ self ]. process := [ [ [ [ self announceNextCommand ] on: ConnectionTimedOut do: [ :e | ] ] repeat ] on: Error do: [ :e | self logger error: 'Error in startAnnouncing e --> ', e greaseString. self error: e. e return

this code looking suspicious. but i not sure what it does, do you override #error: method in your class? what it does? if it not overridden, then by sending self error: you causing another error to be signaled, which is not handled by any handler block so, it will signal an unhandled error exception and finally bail out to OS during startup. To simplify things, what happens is following:

[ self error: 'hahaha' ] fork. instead it should be like:

[ [ self error: 'hahaha' ] on: Error do: [:ex | .. handle error here, and don't let it being unhandled ] ] fork.

...

]. ] forkAt: Processor highIOPriority named: 'Juliet Stomp Announcer'

How can I make this safer, or make it in such a way that the image doesn't crash?

Also is the image destroyed now? Is there a way to start it and bypass this code? Thanks for looking into this.

This happened after a VM crash, when I try to restart I get this in the log. Isn't the error caused by the isEmptyOrNil primitive? Is there anyway for me to access the image now?

an error caused by a primitive failure with invalid socket:

looks like your image was saved with socket being open and upon restart it tries to read data from it. This , of course , causing failure and leads to error signaled.

If you want to track down the error, there is an option in system settings: 'Make a snapshot of new version before quit On unhandled exception, save a new version of image before quit' in 'Headless mode' group.

I am experiencing a lot of random crashes with this VM on OSX 10.6. It just crashed again, and this time I cannot get it to restart. It seems to be crashing in a socket receive class. The stack trace is here :-

This is not a crash, it just quits to OS due to error at startup. To avoid imminent leave to OS, put an error handler around your startup code (i guess it is in CoreMQStompConnection somewhere?).

I don't know if it'd be worth it, but if you're talking about a lot of work lost, it sounds like you could build a debug VM and bypass the loading code from the debugger (like I just had to do).

I saw the screencast where Mariano did something like that. I had just built the image, when the original VM crash happened, so it wasn't that much of a deal to rebuild it. I would like to see some form of safe-mode boot for Pharo, so that just the kernel would be loaded. ST images are all about state, and when production servers go down, it would be nice to be able to start them up, and rewind the app. For normal apps this is not an issue, but when forking processes for socket IO or a FFI call, it is possible to bring it down (or in my case where I think my error handling code caused an error) , and moving in a backup image is not always enough. I would like to get involved in such a project, if there was interest for it. On Fri, Sep 9, 2011 at 18:41, Sean P. DeNigris <sean@clipperadams.com> wrote:

Stef, It's lonely at the top :) Best wishes with your new opportunities. As a linux user, one thing I cringe about is opening a second image and creating a COMPLETE mess of my image. The IDE really needs to detect the problem and refuse to open before badness happens. Otherwise, I make backups (not as often as I should) and good use of recovering lost changes. As for the general problem of building images, I see it much as lack of tools. We need something (Migrate being my evolving solution) that looks at what is installed and can get it into the next image. Metacello is a welcome way to install complicated stuff from others, by *my* code is presumably always something that I want to save and load w/o hassles. FWIW, I have a love-hate relationship with R, and that community is facing a similar problem, and their presumed solution appears to be something that will analyze and build. I realize R's language is awful (raises doubt), but the system as a whole is quite impressive (restores faith).

I would like to be able to rebuild the kernel at startup. Now I should work on it but I got new responsibilities and they take my time. Stef

I would like to get involved in such a project, if there was interest for it.

So do I have to rebuild a new image from scratch now? Is there any command line switch that I can use to by pass the loading of my app on start up?

I don't know if it'd be worth it, but if you're talking about a lot of work lost, it sounds like you could build a debug VM and bypass the loading code from the debugger (like I just had to do).
