| Summary | 0006980: Loading FFI kernel makes NetNameResolver unresponsive | ||||||||||||
| Description |
Image: Squeak 3.10beta7159 and Squeak 3.9#7067 VM: Squeak 3.10.6 (from Aug 30, 2007) on Win Vista Evaluate: NetNameResolver addressForName: 'www.squeaksource.com' timeout: 20 this returns a ByteArray with the IP. After loading FFI 3.9.1 using Universe Browser the above code does not return. (you can only break using cmd-dot) This starts to happen directly after FFI-Kernel-ar-8.mcz is loaded via install script from source.squeakfoundation.org/FFI (with FFI-Kernel-ar7.mcz leads to the same problem) When loading FFI-Kernel-ar6.mcz it works as expected - the IP is instantly returned. So the problem seems to depend on the change from version 6 to 7. Tested on a Squeak3.9 and Squeak3.10 image (see above) |

How does one recreate that problem? I got stuck when trying to "update list from network" with UPackage>>decodeFromXMLElement: so I can't investigate the problem (stack below).

Even if the help -> about tells me "Squeak 3.10beta7159" as version it's the gamma package I downloaded. Please try: http://ftp.squeak.org/3.10alpha/Squeak3.10.gamma.7159.zip [^] and make sure to use the image in a new directory. Steps I've done and that worked to reproduce: 1. World menu "Open" -> "Universe Browser Basic" 2. Button "Update list from network" 3. Select "System" and "FFI version 3.9.1" in the tree 4. Select "Select package" and "Install selections" If you have a problem with package universe browser again we should open another issue. However, the universe browser points to http://map.squeak.org/accountbyid/cf58c358-46ee-465e-b6db-2740e9b32a53/files/InstallFFI3.st [^] a simple script loading FFI-Kernel-ar-8.mcz first and then other packages. To reproduce you can also just add source.squeakfoundation.org/FFI as HTTP repo to Monticello and load FFI-Kernel-ar-8.mcz manually. After that the NetNameResolver addressForName: 'www.squeaksource.com' timeout: 20 does not return anymore. If you load FFI-Kernel-ar6.mcz manually it still works as before loading the FFI Kernel. |

Andreas commented at http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-March/127208.html [^] Yeah, I had forgotten about the problem. The issue comes from a call to Smalltalk>>recreateSpecialObjectsArray (which is required for the FFI to work correctly) and which accidentally nukes the external semaphore table. The fix is simple: Replace the following line in SystemDictionary>>recreateSpecialObjectsArray newArray at: 39 put: Array new. by "Preserve external semaphores when recreating splObjs" newArray at: 39 put: (self specialObjectsArray at: 39). Also, saving and restarting the image after loading the FFI is good temporary workaround for this problem. Cheers, - Andreas |
