Overview

Abscissa is a microframework for building Rust applications (either CLI tools or network/web services), aiming to provide a large number of features with a minimal number of dependencies, and with a strong focus on security.

Documentation

Features

command-line option parsing: simple declarative option parser based on gumdrop. The option parser in Abcissa contains numerous improvements which provide better UX and tighter integration with the other parts of the framework (e.g. overriding configuration settings using command-line options).
components: Abscissa uses a component architecture (similar to an ECS) for extensibility/composability, with a minimalist implementation that still provides such features such as calculating dependency ordering and providing hooks into the application lifecycle. Newly generated apps use two components by default: terminal and logging.
configuration: Simple parsing of TOML configurations to serde-parsed configuration types which can be dynamically updated at runtime.
error handling: unified error-handling subsystem with generic error type.
logging: based on the log to provide application-level logging.
secrets management: the (optional) secrets module includes a Secret type which derives serde's Deserialize and can be used to represent secret values parsed from configuration files or elsewhere (e.g. credentials loaded from the environment or network requests)
terminal interactions: support for colored terminal output (with color support autodetection). Useful for Cargo-like status messages with easy-to-use macros.

Projects Using Abscissa

Crate Structure

Abscissa presently consists of three crates:

abscissa: CLI app and application generator - cargo install abscissa
abscissa_core: main framework library
abscissa_derive: custom derive support - implementation detail of abscissa_core
abscissa_tokio: support for launching Tokio runtimes within Abscissa applications

Minimum Supported Rust Version

Requires Rust 1.56 or newer.

Installation

To generate a new Abscissa application, install the abscissa CLI utility:

$ cargo install abscissa

Usage

After installing the abscissa CLI utility using the method above, run abscissa new <my_app> to generate a new application:

This will generate a new Abscissa application in the my_cool_app directory. For more information, please see the Documentation.

Depencencies

or: "Know Your Dependencies"

One of Abscissa's primary goals is to maximize functionality while minimizing the number of dependencies. Abscissa is used in a number of high-security contexts, and as such we view each additional dependency as additional attack surface and therefore a potential liability. We have therefore been very conscientious about the dependencies we use and will not add additional dependencies without due consideration.

Here are all of Abscissa's transitive dependencies when configured with the default set of features in the application:

Frequently Asked Questions (FAQ)

Q1: Why is it called "abscissa"?

A1: The word "abscissa" is the key to the Kryptos K2 panel.

Q2: "Abscissa" is a hard name to remember! Got any tips?

A2: Imagine you're A-B testing a couple of scissors... with attitude.

Testing Framework Changes

The main way to test framework changes is by generating an application with Abscissa's built-in application generator and running tests against the generated application (also rustfmt, clippy).

To generate a test application and test it automatically, you can simply do:

$ cargo test

However, when debugging test failures against a generated app, it's helpful to know how to drive the app generation and testing process manually. Below are instructions on how to do so.

If you've already run:

$ git clone https://github.com/iqlusioninc/abscissa/

...and are inside the abscissa directory and want to test your changes, you can generate an application by running the following command:

$ cargo run -- new /tmp/example_app --patch-crates-io='abscissa = { path = "$PWD" }'

This will generate a new Abscissa application in /tmp/example_app which references your local copy of Abscissa.

After that, change directory to the newly generated app and run the tests to ensure things are still working (the tests, along with rustfmt and clippy are run as part of the CI process):

$ cd /tmp/example_app # or 'pushd /tmp/example_app' and 'popd' to return
$ cargo test
$ cargo fmt -- --check # generated app is expected to pass rustfmt
$ cargo clippy

Comments

Migrate from `log` to `tracing`
Hi, in Zebra https://github.com/ZcashFoundation/zebra we used @hawkw's tracing rather than log and wrote our own TracingComponent.

Would Abscissa be interested in upstreaming (a modified version of) that component and replacing the default log component with a tracing-based one? In contrast to log, tracing is much more async-friendly, but can remain compatible with log-based crates.

There are some design questions, if this turns out to be of interest to Abscissa:

One of the really killer features of tracing is dynamic filter reloading -- how should this be exposed to Abscissa applications?

In Zebra, we have an HTTP endpoint that allows feeding inputs to the filter reloading. Should Abscissa provide a default mechanism for doing filter reloading? My guess is no, that this is application-specific (e.g., we will probably fold ours into the standard RPC interface).

crates: Replacements for failure?
std::error::Error now contains a trait as expressive as the Fail trait from failure, including downcast support and downcastable Error::source as a replacement for Error::cause (now with a 'static lifetime bound).

Additionally, there are a number of custom derive crates for std::error::Error now available:

err-derive

snafu

thiserror

Given that, it seems like we can eliminate failure as a dependency, potentially replacing failure_derive with one of the crates above.

Serializable Errors

A bit of a sidebar, but one of the things I'd like to eventually accomplish is serde support for the framework's Error type, making it Serialize-able (and ideally Deserialize-able as well), with the intent of serializing them as JSON for reporting to an exception reporting service.

The backtrace crate offers serde support as an optional feature, however accessing this functionality was previously difficult as Abscissa's Error type uses failure::Context to capture and store backtraces. It seems like Abscissa could benefit from providing a similar Context type as a replacement for the one failure provided. Ideally this type could simply derive(Serialize, Deserialize), permitting straightforward serialization of errors as well as their backtraces (and ideally, the entire error chain).

Unfortunately the story around all of this is complicated by adding a Backtrace type to std, presently only available on nightly. This Backtrace type has deliberately minimal functionality.

I'd consider supporting Backtrace on stable a requirement, and ideally preserving the serde serialization support. This seems possible with snafu but needs more investigation.

Crates like err-derive and thiserror have the advantage of being pure proc macros with no additional API dependencies, so if nothing else they stay nicely out of the way and orthogonal to this problem. I imagine if we don't go with snafu, we could pick one of these to be the out-of-the-box custom derive for errors, but with the only framework-level association being inclusion in the default application template (allowing downstream users of the users to potentially remove it or swap it out if they so desire)

Component registry never registers components - component registry doesn't work.

https://github.com/iqlusioninc/abscissa/blob/710e10618d75b3aaa796ad5f5f96c9531fc0171c/core/src/component/registry.rs#L35

It seems that the register function goes through all the motions of registering a new set of components, but never actually mutates the registry to insert them. Is this a known issue, not implemented yet, or am I using the registry wrong?

This breaks the ability to use registered components in applications. In generated application.rs for example:

/// Register all components used by this application.
///
/// If you would like to add additional components to your application
/// beyond the default ones provided by the framework, this is the place
/// to do so.
fn register_components(&mut self, command: &Self::Cmd) -> Result<(), FrameworkError> {
    let mut components = self.framework_components(command)?;
    // expect the application's components register to contain:
    // abscissa_core::terminal
    // abscissa_core::logging
    self.state.components.register(components)?;

    // No components are found :(
    for component in self.state.components.iter() {
        println!("registered component: {}", component.name())
    }
    Ok(())
}

Need help writing tests

I have lots of logging in my application code which is helpful when doing cargo run, but cargo test doesn't have any initialization for config or logging.

Right now, I use println! in my test code, but I'd like to see some of the debug logs from the application code, too.

I also want to test some functions that have calls to app_config(), but right now they fail with an error about config not being initialized.

How should I setup config and logging without running boot in my tests?

update `tracing-subscriber` to 0.2.0

This branch updates the tracing-subscriber dependency to version 0.2.0. This is a major release which includes a couple of important bug fixes; in particular, we've fixed a memory leak caused by spans failing to close their parents, and made significant improvements to performance under high concurrency.

Since this is also a potentially breaking change, I'm trying to help some of our major dependents update by opening PRs against projects that use tracing-subscriber. However, it looks like Abscissa didn't actually use any of the APIs we broke in this release :)

Additionally, while I'm here, I took the liberty of updating the dependency list in the README to reflect changes in transitive dependencies pulled in by tracing-subscriber and tracing. Several dependencies were removed — in particular, the dependency on spin — and a couple were added, but I'm happy to note that the tracing update has a net-negative impact on Abscissa's total number of dependencies. Hopefully this is helpful!

Question: Logging target
As a followup to "Damonizing and encrypting with Abscissa"..

Since I will be running as a daemon, I need to change some logging options:

redirect all logging activity to file

Change output formatting (Time format, add threads etc) Is there a way to do that? I've been digging but don't see a way short of modifying "application" and "trace/component"...

Port to clap v3

This is a reasonably straightforward port of Abscissa to Clap v3 using the custom derives. I removed most of the command subsystem (EntryPoint, Usage, Help) since Clap takes over most of those roles.

To demonstrate how this could work, I also migrated the CLI.

The ergonomics might be improved, as subcommands work differently in Clap than Gumdrop. This is best seen in the commands.rs file of the CLI and gen.rs root command. Embedding subcommands can get tedious quickly.

Another gotcha I found is that #[derive(Runnable)] will not work for structs in its current form, so a manual implementation is necessary.

If this changeset looks like a viable approach, I can take a look at porting the template.

Resolves #298

Replace gumdrop with clap v3 (beta 1)
closes: #298

I've started the work to try to replace gumdrop with clap v3.

Mostly replace dependencies in Cargo.toml files. Replaced gumdrop (0.7) with clap (3.0.0-beta.1)

Replaced attributes that used gumdrop #[option(... with #[clap... since clap supports this with clap_derive

Replaced some gumdrop Error with clap Error

After replacing these, got stuck on core/src/command/entrypoint.rs where the compilation is failing because changes in the file. Especially the command property of this struct. Couldn't find an equivalent way to replace it with clap. Tried to use the #[clap(subcommand)] attribute on this property but it seems make the compiler not to recognize the Cmd type

error[E0412]: cannot find type `Cmd` in this scope --> core/src/command/entrypoint.rs:33:25 | 33 | pub command: Option<Cmd>, | ^^^ not found in this scope

So I believe this is a good starting point but I believe some more fundamental changes will be required in order to replace gumdrop with clap. Especially things related to help and usage which clap supports. So maybe things that currently exist in abscissa like core/src/command -> entrypoint, help and usage might not need to exist or be refactored quite a bit.

Another challenge is that clap also has a concept of App but it's more related to command line arguments and the executable, so it might differ from Abscissa's CliApplication that can track the State.

Anyways, I think we can use this draft PR to have discussions on what is the best way to proceed and I'd be happy to help out with this effort.

Tokio usage: abscissa_tokio::run... take_runtime() stuck in app.write()
I have a Tokio usage question, it may be my understanding of your sequence of events , but I have not been able to determine it from the docs...

I have a set of sub-modules / commands that are dependent upon Tokio runtime. They get called to perform a specific sub-task then return. According to the doc's, Include abscissa_tokio and call run.. I added: components.push(Box::new(TokioComponent::new()?)); then call

impl Runnable for XXXCmd { fn run(&self) { let config = app_config(); let _ = abscissa_tokio::run(&APPLICATION, async{ println!("Started {}", "Junk"); } );

Whcih calls tokio::block_on... Which is essentially what tokio::main does. So, the runtime is initialized, I see all the threads in the debugger, but the app is stuck at (partial stack) app.write TokioComponent::take_runtime TokioComponent::run Waiting for the write lock...

In my case, I have no other component's / services running. So I just need Tokio runtime initialized and available, the terminate after the run is done.

What am I missing...

Any insight would be greatly appreciated...
