feat: agent - eBPF Persist Java symbol table
JAVA symbol persist adapt to repeated agent restarts
Add non-blocking mode for java agent.so
Add exception handling for JAVA agent transmission and ensure timely delivery of information to the file
Socket send adjustments, adding meta send
Add check for HotSpot/OpenJ9 JVM dependency file
Because it's persistent, multiple agents cannot run simultaneously
To determine if the profiler is already running, at any given time, only one profiler can be active due to the persistence required for Java symbol generation, which is incompatible with multiple agents.
To detect the disconnection of the target Java program and output logs
Add handling for the 'JVMTI_EVENT_COMPILED_METHOD_UNLOAD' event
Fix the issue where attach is not possible
Unified Log Output
Implementing thread pool management mechanism
After attaching, clean up the residual files in the target JAVA namespace
Adjustments to Profile JAVA-related configuration items
Modify Java-symbol file generation call interface and adjust the compilation
Modify log output for deepflow-agent check & Modify comment
JVM agent error handling
Adjust the Java symbol collection program
Perform the attach operation using the command line
Rename files related to Java symbol collection
Prevent excessive log output
Add error handling to increase code robustness.
Modify the method for checking if the deepflow-agent process is running
Modify comment
Adjust thread identification Conflicts:
