Compiling Pharo VM used for P8
by Jan VranÃ½ Nov. 28, 2023

Nov. 28, 2023

Hi, I'm trying (and failing) to (re)compile Pharo VM used for P8, more specifically this one (from `pharo -version): Date: Wed Feb 12 11:43:20 2020 CommitHash: 52202d8. I'm targeting linux on x86_64. Whether I use mvm (seems that it was used by Jenkins by then) or cmake I always end up having following errors (just a few, there're loads of them): /usr/bin/ld: vm/vm.a(cogit.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:377: multiple definition of `debugCallbackInvokes'; vm/vm.a(gcc3x- cointerp.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:377: first defined here /usr/bin/ld: vm/vm.a(cogit.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:376: multiple definition of `checkForLeaks'; vm/vm.a(gcc3x- cointerp.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:376: first defined here /usr/bin/ld: vm/vm.a(cogit.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:375: multiple definition of `checkedPluginName'; vm/vm.a(gcc3x- cointerp.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:375: first defined here /usr/bin/ld: vm/vm.a(cogit.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:374: multiple definition of `checkAllocFiller'; vm/vm.a(gcc3x- cointerp.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:374: first defined here /usr/bin/ld: vm/vm.a(cogit.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:371: multiple definition of `breakLookupClassTag'; vm/vm.a(gcc3x- cointerp.o):/redacted/pharo-vm/spur64src/vm/cointerp.h:371: first defined here Does anyone have an idea? Is there a more detailed description of build environment to use? Thanks! Jan

Sockets not working under heavy VM load?
by Pavel Krivanek Oct. 3, 2023

Oct. 3, 2023

Hi, we have some performance issues with Glorp over P3 and, after some investigation, I have a theory that could explain it. And I would like to know your opinion if it is correct. To reproduce this issue, you can try something easy. Just create a process with normal or higher priority that will try to read something from a socket. And, in parallel, do in a separate thread an operation that takes all the processor time for several seconds. ```` [ 5 seconds wait. Time now traceCr. ZnClient new url: 'https://www.google.com'; get. Time now traceCr. ] forkAt: 60. [1000 timesRepeat: [ 10000 factorial ] ] timeToRun ```` (you may try a different safe server address) The processes run in parallel until the time when the first process tries to obtain data from the socket. Then it hangs and waits until finishing of the second process. My theory is that the VM socket plugin is able to receive incoming data from the connection and save it into the buffer. In the meantime, the reading process is waiting on the socket semaphore. But it looks like the plugin is not able to release the semaphore while the VM is actually doing something. It needs to wait until the VM has nothing useful to do, and then it is finally able to release the semaphores so Pharo processes are resumed and can start to read. Is my theory right? Cheers, -- Pavel

ANN: New voyage and mongotalk versions, for mongodb >=5
by Esteban Lorenzano Sept. 14, 2023

Sept. 14, 2023

Hi, We just made a new release of the mongotalk drivers [1], which replaces the drivers for mongodb, making possible for Pharo users to connect with a recent mongo database (versions 5 and beyond). Old legacy driver is still accessible with some minimal work, in case of need [2]. We also updated Voyage to use the new driver by default [3]. Enjoy, Esteban [1] https://github.com/pharo-nosql/mongotalk/releases/tag/v2.0 [2] https://github.com/pharo-nosql/mongotalk#older-mongo-versions--5 [3] https://github.com/pharo-nosql/voyage/releases/tag/v2.0
