deep-java-client's Issues

Metric Tracepoints

Is your feature request related to a problem? Please describe.
Add the ability to create tracepoints that will generate metrics (via the configured service, ie. prometheus). The metric value and lables should be calculated via expressions.

This would allow the ability to dynamically add a metric to track the length of a list for each user (for example).

Given the code (SomeClass.java):

10 public void doSomeWork(String userId, String someNewItem) {
11    var userdata = this.users.get(userId);
12    userdata.add(someNewItem);
13 }

We could add a tracepoint with the config:

{
  "file": "SomeClass.java",
  "line": 12,
  "metrics":[
    {
      "name": "user_data",
      "type": "gauge",
      "expression": "userdata.size()",
      "labels": {
          "user_id": "userId"
      }
    }
  ]
}

Additional context
Ensure that the metrics can be collected by the various providers that are common:

prometheus
otel

Can't load CFPlugin for ColdFusion 2023 on Windows

Describe the bug
When the ColdFusion 2023 service is ran on Windows, the sun.java.command system property doesn't exist.

This causes an NullPointerException to be thrown whilst loading the CFPlugin as the isActive method will use Utils.isCFServer to check that the property contains coldfusion.

This is a bigger problem since Deep's plugin loader changed as the previous plugin loader would have caught this exception preventing an interruption to Deep's startup.

To Reproduce
Steps to reproduce the behavior:

Install CF 2023 service on Windows
Attempt to start Deep with CFPlugin (was found via FusionReactor)

Expected behavior
Deep fails to start.

When started via the FusionReactor integration, FusionReactor will wait for Deep to be started, causing log spam and potentially blocking FusionReactor from starting fully.

Describe the bug
When running test app on Java 20.0.2-open this error is given:

To Reproduce
Steps to reproduce the behavior:

Go to 'intergral/test-app-java'
Configure to use Java 20.0.2-open (easiest to use sdkman)
Run app
See error in logs

Expected behavior
Should install and trigger tracepoint.

Additional context
Probably need a new version of ASM.

Use SPI to load plugins

Is your feature request related to a problem? Please describe.
Class loading can be complex in Java environments. We can change the plugins to use SPI to help mitigate these issues.

Describe the solution you'd like
Change all plugins to load via SPI, and remove the DeepAPI#registerPlugin API. This should help reduce the user error when creating and registering custom plugins.

Additional context
Will have to address how the FusionReactor integration is done with this change.

Failed plugins can prevent startup

Describe the bug
On startup then plugins can throw exceptions. This can cause deep to not start.

To Reproduce
See #113

Expected behavior
Should load all successful plugins.

Logging tracepoint

Is your feature request related to a problem? Please describe.
Have the ability to inject log messages into running code.

Describe the solution you'd like
Attach log messages to tracepoint to be injected and logged by the application.

Improved support for maps

Is your feature request related to a problem? Please describe.
Currently if a map is collected the key is always converted to a string, meaning that complex keys do not work.

Describe the solution you'd like
Wrap the key entries in a deep.MapEntry type. This allows the UI to treat all maps from all languages the same. This type should then define child variables as:

{
 type: 'deep.MapEntry',
 value: '0',
 hash: '123.0',
 children: [
    {
      id: '124',
      name: 'key'
    }
    {
      id: '125',
      name: 'value'
    }
  ]
}

Describe alternatives you've considered
Add explicitly the fields for map entries.

Additional context
Look at how NV handled this.

The Deep java agent can break applications that depend on grpc-netty-shaded

Describe the bug
When using grpc-netty-shaded as a maven dependency, at the same time as using the Deep java agent, the dependency can attempt to load services defined in the Deep jar (META-INF/services/).

To Reproduce
Steps to reproduce the behavior:

Create a project which uses the grpc-netty-shaded dependency

Maven - pom.xml

<dependencies>
    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-netty-shaded</artifactId>
        <version>1.36.1</version>
    </dependency>
</dependencies>

Java - Main.java

import io.grpc.netty.shaded.io.grpc.netty.NettyChannelBuilder;
import java.net.URI;

Span Tracepoints

Is your feature request related to a problem? Please describe.
Create a way to generate a trace around a block of code (function/method) based on a tracepoint.

Describe the solution you'd like
Allow the tracepoint argument 'method_name' to to used in conjunction of a filename (in leu, or as well as line number).

If a method/function is found that matches the argument, then the function is wrapped in a span and attached to the existing span collection services (e.g. otel). If a line number is also specified then a normal tracepoint will be triggered on that line with in the original code. If there is no tracing supplier discovered or provided than no traces will be generated, and the tracepoint will either be ignored or simple act as a normal tracepoint.
