[Pharo-dev] Jenkins slaves
Hi all, An hypervisor used to host slaves for the continuous integration service is reaching its maximum storage capacity (primary storage used for running Virtual Machines). To avoid VM corruptions, we preventively stopped VMs running on this hypervisor. For the pharo ecosystem, following VMs are impacted: pharo linux-ubuntu-10-04 test2 pharo-contribution linux64-2 74 rmod windows-7-32 They will be restarted once the storage will be extended (probably in the beginning of the next week). If really needed, it is possible to create new slaves to substitute to these ones since they will be hosted on another hypervisor. Apologies for the inconvenience, Christophe.

We can also add a mac slave in our offices. We just have one for pharo / pharo-contribution / rmod.

[Pharo-dev] How do diagnose image locks up (cpu 100%) on save?
Hi - The plain Pharo 20619 + RFB image in my dropbox here: https://dl.dropboxusercontent.com/u/4460862/pharo2RFB.zip freezes when you save it while the RFB server is running. The freeze occurs in the #snapshotPrimitive.

I'm reluctant to make it stop and start the RFB server through the snapshot because it will kick off all attached clients. Of which there is at most one and its me, so it wouldn't be too bad but its not desirable. It freezes whether there is a client connection or not. Thanks Paul

Paul, Zinc HTTP Server are stopped/started on each image save. For HTTP 1.1 that is OK, protocol wise. I think that RFB should do something similar to prevent issues like the one you are reporting (and there have been many in the past as well). Consider this: if you save but do not quit, and you later abort the image hard, you would expect the saved image to work, right. That can only be with a fresh server socket. Sven Thanks Paul

Re: [Pharo-dev] [Pharo-fuel] Fuel API bug
hi henrik do you have an implementation for when:do:for: because I do not see it? https://pharo.fogbugz.com/default.asp?11316 Stef #when:do: is there already ;) even better then :) #when:send:to: and #when:do:for: should be added though. what would be when:do:for: ? Its use is to specify a non-standard subscriber. In VW it is pretty much mandatory when using weak subscription, as VW subscribes the block. In Pharo it's much less useful, both because the at the moment weak when:do: doesn't work, but also since Pharo subscribes the block's receiver by default, which is what you want in 95% of cases. Still nice to have around in the edge cases one might still need it though. Cheers, Henry

I'm reluctant to make it stop and start the RFB server through the snapshot because it will kick off all attached clients. Of which there is at most one and its me, so it wouldn't be too bad but its not desirable. It freezes whether there is a client connection or not. Paul, Zinc HTTP Server are stopped/started on each image save. For HTTP 1.1 that is OK, protocol wise. I think that RFB should do something similar to prevent issues like the one you are reporting (and there have been many in the past as well). Consider this: if you save but do not quit, and you later abort the image hard, you would expect the saved image to work, right. That can only be with a fresh server socket. Sven Thanks Paul I think the 'abort the image hard' problem is taken care of in the #startUp: method on the RFBServer. It checks if the image is resuming and the server is/was running and if so stopping then restarting the RFB server. I don't want to stop and restart the server every time there is a save. I'm fine doing it on startup after a quit or abort as you describe. Anyway, from the stack dump I posted I cannot tell for sure but it seems like a VM bug. -- View this message in context: http://forum.world.st/How-do-diagnose-image-locks-up-cpu-100-on-save-tp4704639p4704689.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

So when you open the image I posted and in the workspace run RFBServer start. Smalltalk snapshot: true andQuit: false. Everything works fine? It doesn't go to 100% cpu use? -- View this message in context: http://forum.world.st/How-do-diagnose-image-locks-up-cpu-100-on-save-tp4704639p4704698.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
[Pharo-dev] Debugger recursion
Hi, try this: This will start opening infinite number of debuggers, because of AdoesNotUnderstand: #halt. Ok, so, if I replace /self halt/ with /Halt signal/, it will do the same, but now because of AdoesNotUnderstand: #inspector. But in both cases, after successfully (before stack is full) interrupting the recursion with Alt+., only the Process Browser is full of Morphic UI process:MorphicUIManageropenDebuggerOn:context:label:contents:fullView: no real debugger is visible... My question: How to debug code inside DNU method? Bug? Feature? I know, the full stack issue can be solved by a watchdog, is it planned? And it was discussed before here on mailinglist, but with different code examples. Or one can limit the total count of opened... - Save The World! -- View this message in context: http://forum.world.st/Debugger-recursion-tp4704703.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
