Aqua: Enabling Latest Release Fetch for HTTP Packages

Hey everyone! Today, we're diving deep into a support request focused on enhancing Aqua's capabilities. Specifically, we're looking at enabling Aqua to fetch the latest releases of HTTP-type packages. This is a feature that many of you have been asking for, and we're excited to explore the possibilities. Let's break down the issue, the proposed solutions, and what it all means for your Aqua experience. So, let's dive in and see what this is all about!

Understanding the Issue

In the world of Aqua, packages come in different flavors. Two key types are:

  • HTTP-type packages: These are packages that are downloaded directly from a URL. Think of tools hosted on personal websites or smaller projects where a dedicated release repository might not exist.
  • GitHub-release-type packages: These are packages that are released on GitHub, making it easy to track versions and fetch the latest releases.

The core issue here is that Aqua currently doesn't automatically fetch the latest versions for HTTP-type packages. This means users have to manually specify the version they want, which can be a hassle. This can be a bit of a pain, right? Imagine having to constantly check for the newest version of your favorite command-line tool and then manually updating your Aqua configuration. No fun!

Let's look at a real-world example. Our user was trying to install ncdu, a handy disk usage analyzer, using Aqua. They encountered an error because Aqua couldn't figure out the latest version. Here’s the error they saw:

mise WARN Remote versions cannot be fetched: aqua package dev.yorhel.nl/ncdu does not have repo_owner and/or repo_name.
mise WARN No versions found for aqua:dev.yorhel.nl/ncdu
mise ERROR Failed to install aqua:dev.yorhel.nl/ncdu@latest:
   0: HTTP status client error (404 Not Found) for url (https://dev.yorhel.nl/download/ncdu-latest-linux-x86_64.tar.gz)

This error message tells us that Aqua couldn't fetch the latest version of ncdu because it didn't know where to look. The user then tried to reproduce this issue directly in the Aqua registry, confirming that the problem wasn't isolated.

Diving Deeper into the Problem

The user's investigation led them to a crucial realization: Aqua's current design doesn't support automatic fetching of the latest versions for HTTP-type packages. Unlike GitHub-release-type packages, which have a clear mechanism for version tracking, HTTP-type packages often lack a standardized way to determine the latest release. This limitation forces users to manually manage versions, which can be time-consuming and error-prone.

To illustrate this further, consider the steps the user took to reproduce the issue:

  1. Cloned the Aqua registry.
  2. Installed the necessary tools for contribution.
  3. Tried to install ncdu using aqua i dev.yorhel.nl/ncdu.

This resulted in an error because Aqua couldn't resolve the [SET PACKAGE VERSION] placeholder, as it had no way of knowing the latest version. This highlights the core challenge we're addressing: how can we enable Aqua to automatically fetch the latest versions for HTTP-type packages?

Proposed Solution: Querying Release Monitoring APIs

So, how can we solve this? The user suggested a clever approach: leveraging the Release Monitoring API. Specifically, they pointed to https://release-monitoring.org/api/v2/versions/?project_id=6045, a service maintained by Fedora Infrastructure that tracks releases across various projects. The idea is that Aqua could query this API (or similar ones) to determine the latest version of an HTTP-type package. This sounds like a promising way forward, doesn't it?

This approach could potentially automate the version fetching process for many HTTP-type packages. Imagine Aqua seamlessly querying the Release Monitoring API, identifying the latest version of ncdu, and installing it without any manual intervention. That's the dream!

Breaking Down the Proposal

To ensure we're all on the same page, the user posed three key questions:

  1. Is it true that HTTP-type packages in Aqua currently can't fetch their latest version, and a collection of available versions is not maintained by design?
  2. Is the idea of giving HTTP-type packages the ability to fetch their latest version, similar to GitHub-release-type packages, not planned/implemented yet, and is this idea welcomed?
  3. Is the entire premise of this support request flawed, indicating a misunderstanding of the project's goals?

These questions are crucial for clarifying the current state of Aqua and the feasibility of the proposed solution. They help us understand whether the user's assumptions are correct and whether their suggestion aligns with the project's roadmap.

The first two questions directly address the core issue: the lack of automatic version fetching for HTTP-type packages. The third question is a healthy dose of self-doubt, ensuring that we're not barking up the wrong tree. It's always good to question our assumptions and make sure we're addressing the problem effectively.

Reproducing the Issue: A Step-by-Step Guide

For those of you who want to get your hands dirty and reproduce the issue, here’s a step-by-step guide:

  1. Clone the Aqua registry:

gh repo clone aquaproj/aqua-registry -- --depth=100 --jobs=4

2.  Install the tools required for contribution:

    ```console
aqua i -l

  1. Inspect the Aqua configuration for ncdu:

aqua g


    You'll notice that the version is set to `[SET PACKAGE VERSION]`, indicating that Aqua doesn't know the specific version.
4.  Attempt to install `ncdu`:

    ```console
aqua i dev.yorhel.nl/ncdu

This will result in the error we discussed earlier, confirming that Aqua can't fetch the latest version.

By following these steps, you can experience the issue firsthand and understand the pain points we're trying to address.

Expected vs. Actual Behavior

  • Expected behavior: aqua i dev.yorhel.nl/ncdu should fetch the latest version of ncdu (e.g., 2.9.2) and install it without errors.
  • Actual behavior: Aqua fails to download the package, resulting in a 404 error because it can't resolve the version placeholder.

This discrepancy highlights the gap between what we want Aqua to do and what it currently does. It underscores the need for a solution that enables automatic version fetching for HTTP-type packages.

What's Next? Discussion and Implementation

So, where do we go from here? The next step is to discuss the proposed solution and explore the feasibility of implementation. This involves:

  • Evaluating the Release Monitoring API: Is it reliable? Does it cover a wide range of HTTP-type packages? Are there alternative APIs we should consider?
  • Designing the implementation: How would Aqua query the API? How would it handle different API responses? How would it store the fetched version information?
  • Testing and refinement: Once implemented, how do we ensure the solution works correctly? What edge cases do we need to consider?

These are all important questions that need to be answered before we can move forward. But the initial response to the user's suggestion has been positive, and there's a strong sense that this is a valuable feature to add to Aqua.

The Importance of Community Input

It's crucial to emphasize that this is a community effort. Your input, feedback, and ideas are essential for shaping the future of Aqua. We encourage you to participate in the discussion, share your thoughts, and help us build a better tool for everyone.

Whether you're a seasoned Aqua user or a curious newcomer, your voice matters. Let's work together to make Aqua even more powerful and user-friendly.

Conclusion

Enabling Aqua to fetch the latest releases of HTTP-type packages is a significant step forward. It addresses a key limitation in the current design and promises to streamline the user experience. By leveraging release monitoring APIs, we can automate the version fetching process and make Aqua even more versatile.

This support request highlights the power of community collaboration. By identifying a problem, proposing a solution, and engaging in constructive discussion, we can collectively improve the tools we use every day. So, let's keep the conversation going and make Aqua the best it can be!

Thanks for reading, guys! Stay tuned for updates on this exciting development. We're stoked to see where this goes and how it will enhance your Aqua experience. Keep those ideas coming, and let's build something awesome together!
