AdjustHelper.setupAdjustIfNeeded(this);
}
}
```
### Thought:
The onCreate() function performs necessary initializations such as loading certain preferences, and sets up SearchEngineManager instance. However, loading preferences depends on the Search Engine manager, because the default search engine preference uses the search engine manager; we therefore need to ensure that preferences aren't loaded until search engines are loaded, to avoid potential hangup of the application for a fresh install. The following optimized code first initializes the search engine manager and then loads preferences.

### Thought:
This is a simple Java class that is responsible for scanning a list of ports and establishing a socket connection on those ports. If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.

### Thought:
This is a simple Java class that is responsible for scanning a list of ports and establishing a socket connection on those ports. If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.

}
```
### Thought:
This is a simple Java class that is responsible for scanning a list of ports and establishing a socket connection on those ports. If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.

}
```
### Thought:
This is a simple Java class that is responsible for scanning a list of ports and establishing a socket connection on those ports. If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.

this.ip = ip;
this.startPort = startPort;

this.delegate = delegate;
}
@Override
public void run() {
for(int i = this.startPort; i <= this.stopPort; i++) {
try {
this.delegate.processFinish(0);
Socket socket = new Socket();
socket.setReuseAddress(true);
socket.connect(new InetSocketAddress(this.ip, i), 4000);
socket.close();

catch(IOException e) {

}
}
}
```
### Thought:
This is a simple Java class that is responsible for scanning a list of ports and establishing a socket connection on those ports. If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.

NoFunEval: Funny How Code LMs Falter on Requirements Beyond Functional Correctness
[Published at COLM'24]
Abstract:
Existing evaluation benchmarks of language models of code (code LMs) focus almost exclusively on whether the LMs can generate functionally-correct code. In real-world software engineering, developers think beyond functional correctness. They have requirements on "how" a functionality should be implemented to meet overall system design objectives like efficiency, security, and maintainability. They would also trust the code LMs more if the LMs demonstrate robust understanding of such requirements.
We propose a new benchmark NoFunEval to evaluate code LMs on non-functional requirements and simple classification instances for both functional and non-functional requirements. We propose a prompting method, Coding Concepts (CoCo), as a way for a developer to communicate the domain knowledge to the LMs. We conduct an extensive evaluation of twenty-two code LMs. Our finding is that they generally falter when tested on our benchmark, hinting at fundamental blindspots in their training setups. Surprisingly, even the classification accuracy on functional-correctness instances derived from the popular HumanEval benchmark is low, calling in question the depth of their comprehension and the source of their success in generating functionally-correct code in the first place.

Example eval script (For maintainability)
bash evaluation_example_script.sh
Parameters
| Parameter | Description |
|---|---|
data_subset |
The subset of data to use. Options: latency, resource_util, maintainability, security, runtime_efficiency for nofunedit. Additionally humanevalclassify for classification. |
model_path |
The path of the model from HF. Example: WizardLM/WizardCoder-15B-V1.0. |
prompt |
Prompt to use. Options: base_prompt, one-shot, chain_of_thought, coding_concepts. |
num_samples |
Number of samples to generate. Example: 1 (We used 1 for greedy and 20 for higher temperature). [NoFunEdit - Generation only] |
max_new_tokens |
Budget for new token generation for a model. Example: 1200 (NoFunEdit: We used 1200 for runtime_efficiency and security for all prompts than CoT where 1500 was used. For others, we used 5192 or max possible limit. Classification: We used 4 for all generations). |
temperature |
Temperature for model generation. Example: 0 (We used 0 for greedy and 0.8 for higher samples) |
score_k |
K vales for Score@K. Example: 1,5,10,20 (Should not be greater than num_samples and is comma separated) [Eval only] |
metric |
Metric to be used for evaluation. Option: diffbleu, codeql, codeql-diffbleu (to be run after first two params are run), classification, runtime [Eval only] |
VLLM Parameters (for generation)
| Parameter | Description |
|---|---|
batch-size |
Batch size. Default: 1 |
precision |
Floating point format: Default: fp16 |
tensor_parallel_size |
Default: 1 |
swap_space |
The size (GiB) of CPU memory per GPU to use as swap space: Default: 4 |
