问题 I am running my TeamCity 7 server and agent on MacOS. My repo is on github. I use ssh and I know that the authentication is correctly configured, because the test is successful. The build works fine when I use VCS Checkout Mode "Automatically on server", however when I use VCS Checkout mode "Automatically on agent" I get this error. [13:40:35][Updating sources] Failed to perform checkout on agent: '/usr/bin/git fetch --progress origin +refs/heads/master:refs/remotes/origin/master' command

问题 I've started to implement a simple Java agent that does some instrumentation before a class is loaded by JVM. The thing is I need to do some debugging on this agent, but what I tried so far had failed( I tried to remote debug the agent but it's not working) I use IntelliJ and Maven( to generate the .jar agent). So my question:Is there any trick to remote debug a simple java agent? 回答1: As it turns out I have a project that demos Java instrumentation, which I have tested out debugging in

Generic reply from agent/mailboxprocessor?

阅读更多关于 Generic reply from agent/mailboxprocessor?

问题 I currently have an agent that does heavy data processing by constantly posting "work" messages to itself. Sometimes clients to this agent wants to interrupt this processing to access the data in a safe manner. For this I thought that posting an async to the agent that the agent can run whenever it's in a safe state would be nice. This works fine and the message looks like this: type Message = |Sync of Async<unit>*AsyncReplyChannel<unit> And the agent processing simply becomes: match mailbox

jvmti agent deadlock

阅读更多关于 jvmti agent deadlock

问题 When I run my jvmti agent with a java program, it seems that jvm encounters a deadlock. In my jvmti agent, I create a single raw monitor in Agent_OnLoad() and enter that lock at the beginning of every callback function and exit that lock at the end of every callback functions. I don't know the reason of this deadlock. Is there any other possibilities of deadlocks in jvmti agents? thanks. 回答1: Yes, there is a possibility of deadlocks in JVMTI Agent. The JVMTI Reference states: The same thread

Automated Exception Handling

问题 I was wondering if something exists (in Java world) able to take an snapshot of the JVM current state with the following features: Do it while an exception is being thrown. Capture local variables, method's arguments, etc. Put it in a handy file which can be used to extract or reproduce in a IDE the situation in your source code. The two first features are required (third would be awesome). And it must be suitable for production use (so, there is no way about debuggers). Before asking this I

JADE action() not working

阅读更多关于 JADE action() not working

问题 I think I am missing something in my project. I need agents to perform specific task that I assign. I am using JADE. Inside the action() I wrote a for loop to display numbers 1 to 10.

When I run: java -cp jade.jar jade.Boot -gui agent:TestAgent I get a classNotFound Exception and also shows agent can't be created. When I run: java -cp jade.jar jade.Boot -gui -agent agent:TestAgent I get info as agent ready, but the
