Hi, My application triggers the BoehmGC stop the world collection, and the application hangs after that. If I am in debug mode I can see that a SIGUSR1 signal is received, but resuming the program doesn't do anything. I have attached all stack traces of all running threads at the moment the SUGUSR1 comes in. I am totally clueless here, since I don't have any knowledge of the threading and BoehmGC internals. This occurs while downloading a big file via the java socket API. After disabling the GC, the download works, but downloading with GC on, always hangs. Thread 7 is the download Thread. Thread 5 is a blocking UDP Socket that waits for incoming data. I tried to implement UDP support and reused stuff from apache harmony. Maybe I'm doing something wrong there, too... Would be great if anyone could poke me in the right direction, where to look for a solution... Anyway here are my stacktraces: Thread 1 #0 0x906fcafa in mach_msg_trap () #1 0x906fd267 in mach_msg () #2 0x025e3d86 in __CFRunLoopServiceMachPort () #3 0x02540e74 in __CFRunLoopRun () #4 0x02540840

My first inclination was to say this is something we're working on, but I was expecting to see pthread_mutex_lock in at least one of the stack traces. It could still be that issue, but it's not as apparent. As a TEMPORARY HACK (both of those words are important), you could try setting GC_finalize_on_demand to 1 as your program is starting up, but I must stress that is temporary. That by itself will give you a memory leak on any Objects with finalizers, but will garbage collect the rest. We are working on an issue where the garbage collector currently runs the finalizers in the same thread in which a new Object was allocated. That in turn allocates other Objects, causing either a blocking thread or an infinite loop, depending on the setup.

Setting GC_finalize_on_demand to 1 does not change the behavior. Anything other I can try?

If I am in debug mode I can see that a SIGUSR1 signal is received, but resuming the program doesn't do anything. I have attached all stack traces of all running threads at the moment the SUGUSR1 comes in. I am totally clueless here, since I don't have any knowledge of the threading and BoehmGC internals.

I don't think the hack you propose is going to work (although Markus, please try Paul's suggestion). The reason I don't believe this is going to work is because none of the stack traces is calling a finalizer. I know that the GC performs a world stop on all threads when it does its thing (it must do that in order to get a consistent snapshot of the object graph for the mark-and-sweep algorithm). It is possible that GC_stop_world () conflicts with something we do with the threading API. @Markus: can you identify the reason for the SIGUSER1?

Hi everyone, XMLVM is really a great work. I have installed it on a windows machine, eclipse and jdk 1.6. Demos are ok, I can run them with success. When a try to migrate an existing Android project I don't receive any message, and no skeleton is created inside the project folder. This is the command I have executed: C:\>xmlvm --skeleton=android:migrate --out=e:\workspace_android\HelloProject The same beaviour when I execute a new project task C:\>xmlvm --skeleton=android:migrate --out=e:\workspoid\NewProject --app-name=XMLNP I don't receive any message, the commands are executed without output, and no project are migrated/created. xmlvm/bin in on the system path Any idea? Thank's in advance Devone |

Hi everyone,
while I can successfully compile and run demos, I cannot compile a migrated
project.
The problem is that the ant task "compile" doesn't find the sdk.dir.
This is the response:
macpro$ ant run
Buildfile: /Users/macpro/Documents/workspace/Myapp/build.xml
-xmlvm-init:
-xmlvm-init-target:
-xmlvm-requirement:
run:
BUILD FAILED
/Users/macpro/Documents/workspace/Myapp/nbproject/xmlvm.xml:60: The
following error occurred while executing this line:
/Users/macpro/Documents/workspace/Myapp/nbproject/build-Android.xml:7:
Property 'sdk.dir' should properly be defined in 'local.properties' file.
Please define the location of the Android SDK in order to compile the
Android project. Compilation will abort now.
Following the content of local.property
# The location of the AndroidSDK.
# Since this file is included in all Android demo projects, it is advised
# to use an absolute path, or else the demo projects will not be properly
# configured.
#
sdk.dir=${user.home}/android-sdk-mac_x86
xmlvm.install=${user.home}/xmlvm
Same result if the property is set to /Users/macpro/android-sdk-mac_x86
Can someone help me?
Thanks in advance
Devone

Does the file /Users/macpro/android-sdk-mac_x86/tools/android exist? |

Solved:
the migrate command doesn't copy the local.properties from xmlvm folder to
my project folder.
Adding it manually all works successfully.
Bye

The parameter is: --debug=all |

Executing the command with the --debug=all parameters the result is the same, the command end without output. This is command and the empty output: C:\>xmlvm --debug=all --skeleton=android:migrate --out=e:\workspace_android\Events C:\> Is there a log file for xmlxvm commands? D >Can you run the same command with maximum debug information? >The parameter is: --debug=all |
