Quicklisp doesn’t use TLS or signatures? How have I not heard this before?

That would be unbelievably irresponsible. Has this really not been addressed by the CL community?

Edit: here’s the issue: https://github.com/quicklisp/quicklisp-client/issues/167

Thanks for bringing this up!

The reason for this is quite simple: portability. Quicklisp also uses plain TAR files to distribute dists. Why? Because quicklisp has a built-in TAR extractor written in 100% standard/portable CL. This allows Quicklisp to run on just about everything, from your computer to real LispMs and operating systems like Mezzano.

TLS comes up every time someone discusses Quicklisp, but nobody bothers to go ahead and actually implement it portably (and even if they did, have fun with performance and side channel attacks, both of which require you to break portability to implement well for every platform you want to target).

If you would like a more stereotypical package manager, consider using CLPM. Though one of the big reasons to use CLPM is not encryption IMO, but versioning. ASDF supports locking versions of dependencies, but Quicklisp doesnt ever use this and instead constantly pushes latest of everything from git repositories. This IMO sucks a lot more than using plain HTTP given that this actually breaks code, whereas some MITM from plain HTTP connection to Quicklisp would require so much coordination (and specificity of target) that it's just not in my threat model at all.

Yeah, I didn't recall off hand, but this was one of my main complaints with Quicklisp vs. other package managers I've used (for other ecosystems--not CL).

> whereas some MITM from plain HTTP connection to Quicklisp would require so much coordination (and specificity of target) that it's just not in my threat model at all

I hope you're right, but it still seems like an unnecessary risk. Even if I can't imagine a scenario where someone is able to MITM me (or, more likely, a server I'm deploying code to), there's still the lingering feeling that it's possible. I certainly wouldn't download an executable over HTTP and run it, and downloading library code is fairly similar (although easier to inspect, at least).

This does keep coming up, and it's a few years old now. I think Quicklisp can easily still support https while supporting the older packages that are tar+http, which could easily be mirrored in a git repo. Quicklisp has unfortunately taken over the entire ecosystem, making it hard to use anything else, and you often need to depend on it to use a lot of tools in the ecosystem. It sort of reminds me of Systemd in that way.

I agree on the version pinning being a worse situation, and also not having something like "node_modules" for lisp. I haven't tried CLPM since a while back, it was kind of hard to setup back then.

I have a little package manager thing, cl-micropm, that just uses Quicklisp to fetch everything via docker (should probably support podman too), and an .envrc file to tell ASDF to look in the project directory (a project-local node_modules-like folder called "lisp-systems") for systems. That way I can pin my deps manually by picking the commits + git submodule in lisp-systems/, and it's isolated to my local project. I looked into using the Docker container to rewrite the requests to use https, bypassing whatever Quicklisp is doing, but I never got around to that.

I'm looking to switch it to something even simpler/explicit though, cl-pm, that'll only optionally need/use Quicklisp via podman _only_ to figure out what the dependencies are, and then just have a function that uses wget/curl/git-pull to conveniently explicitly pull them in on request. That way you can decide to add a git mirror for an old http library, or pin a specific version, etc. It's slightly more manual than Quicklisp or CLPM, not a big deal, but very easy for anyone with just a little bit of lisp knowledge to understand the whole thing in under an hour.

This is a strange statement.

What requires QL to work? In the "bad old days" you had to manually download the sources and drop them somewhere ASDF could find them[1]. This still works. You can blithely live as if QL does not exist and get that same experience.

1: Yes, there was asdf-install, but I think I managed to get that to work once with about half-a-dozen tries?

Ultralisp, Rowsell, Qlot, Quickdocs, etc. Virtually every modern project build/install instructions reference Quicklisp. You have no idea which dependencies you need to pull and from where, which can be a real PITA for a large project. A lot of project code I've looked at also has Quicklisp references in the actual code for whatever reason, usually for testing or building or whatever else, so to run those you need Quicklisp. It's really hard not to say it's taken over the ecosystem or that there isn't lock-in, I don't know what you mean to be honest. Quicklisp is also a curated list gatekept by one person, so whatever is on there isn't really representative of everything that's being worked on. You can publish on Ultralisp if you don't want to wait or if it wasn't accepted, but then you're still using Quicklisp under the hood. And it's hard to discover things on Github/Gitlab/etc because there's a lot of stub repos just trying things out, with little to no stars.

I'd love to see ecosystem support for other package managers. CLPM is still in beta and has been for a good while now. Quicklisp too. Quicklisp famously doesn't support HTTPS, version pinning, project locals, etc, which has really throttled any progress with the Common Lisp ecosystem. It's not like ASDF at all, which is become a standard that's built into a lot of the lisp compilers.

Before QL, you looked at the .asd and searched cliki for each name. You can still do that if you like (and can use Google as well). Sometimes the readme had better instructions, but often they didn't work.

In fact, each project in the QL repository includes a link to upstream, so you can use that to find your sources if you like

I literally once rewrote the 20% of a library that I personally needed because it was faster than tracking down all the dependencies.

Your original comment reads like there used to be all these awesome package managers, and QL came around and squashed them, but there was rather a giant vacuum that QL quickly filled.

> Before QL, you looked at the .asd and searched cliki for each name.

Only very few libraries are on Cliki, and the links "upstream" just link to the repo that almost always says to just use Quicklisp for installation. Quicklisp has a quicklisp-projects repo where the project sources are all in one place, but it's not very helpful for what I've been talking about.

> Your original comment reads like there used to be all these awesome package managers

Sorry I don't want to engage with flamebait... I commented on this thread to raise awareness for issues and interesting things that I think people here might find useful, because there's still a lot of interest in lisp.

If you really think I'm wrong, do a writeup and share it on HN with everyone. You can go to the awesome-cl repo to find the most popular libraries in the ecosystem, and show how easy it is to avoid using Quicklisp to install/build/find the deps/run tests for all those repos. It would really help and I think it would save a lot of people time. For something like the Nodejs ecosystem, for example, such a writeup would probably only take like an hour tops because of the maturity of the npm package manager.

I picked dexador because Fukamachi likes lots of small projects, so it's going to have lots of deps; it took me about 50 minutes while watching baseball and chatting with family:

I should also note that, should you want to avoid reading the .asd file, you can skip steps 2-4 and just download dependencies as-needed.

This is literally what my workflow was for using 3rd party Lisp projects the day before QL came out. Prior to my discovery of Google it was even more of a pain.

I've never successfully gotten a Nodejs project working without NPM, but NPM vies with pypi for my second least favorite packaging ecosystem (haskell cabal "wins" this contest).

Quicklisp doesn’t need to support TLS, but it does need to support authentication of some sort. Signing files would be good enough.

Are you proposing authentication over an insecure connection? If so, then the credentials could be compromised by a middle man. The same would be true for the signatures.

I don't really buy this argument at all.

There is no technical reason why quicklisp couldn't use the systems libcurl and openssl when its available and fallback to fetching with its portable http implementation when they aren't available.

Every other languages package manager has managed to solve this issue!

If the issue is that nobody has actually had time to work on it, that's fair, but I don't believe that optionally supporting libcurl would cause QL to be less portable.

Try ocicl instead of quicklisp. System tarballs are hosted in an OCI registry, and are downloaded via TLS connections (obeying proxies). Tarballs are signed and signatures are stored in the sigstore rekor transparency log for later inspection. https://github.com/ocicl/ocicl

Just wanted to say I did see your other comment and am intrigued by ocicl. Thanks!

> I have some cons

I’m sure you do :°)

These issues get mentioned a lot, you just haven't noticed I guess. Sourceforge is also an issue with some C libraries too, I'm guessing because it was done a long time ago? not sure.

I use ECL because it has really good C interop. It actually lets you inline C and access macros directly, making it a great glue language for C libraries. It's what I'm using it for now. I think you might even be able to avoid the GC entirely and use it to script C programs together in a performant way, by using the C FFI to allocate and manage the memory, including the ECL types, instead of the GC. And that's actually doable because of how good the inspector/debugger for lisp is. You can even inline assembly. I'm working on a bunch of CL stuff around this sort of thing, I plan to do a writeup of it and share it once I've developed it more.

Lisp has it's downsides, but the C FFI/embeddability, along with the excellent low-level debugger/inspector, interactivity, and conditions and restarts, makes it worth the time for me to invest in it. And the stability of the language. My main gripe is the reader, but it's easy-ish enough to avoid the problems with named-readtables, or a simple lisp parser for `read` or whatever. I like Clojure, but it's missing some key stuff from the old lisp world that I'd love to see. Shadow-cljs is awesome.

When I started using CL 20 years ago, libraries were stored on cliki and any malicious user could put malware there. Any source you asdf-installed was generally GPG signed and the installer automatically checked signatures against your personal trust-chain.

Learning CL back then was my first introduction to GPG (and Emacs, and Linux)

> When I started using CL 20 years ago, libraries were stored on cliki and any malicious user could put malware there. Any source you asdf-installed was generally GPG signed and the installer automatically checked signatures against your personal trust-chain.

Which, in practice, involved downloading GPG public keys from cliki because I didn't know every single CL developer.

Solutions for the lack of https:

- add in https://github.com/rudolfochrist/ql-https (downloads packages with curl)

- use another package manager, CLPM: https://www.clpm.dev (or the newest ocicl)

> CLPM comes as a pre-built binary, supports HTTPS by default, supports installing multiple package versions, supports versioned systems, and more.

- use mitmproxy: https://hiphish.github.io/blog/2022/03/19/securing-quicklisp...

Nix has a really convenient new CL libraries packaging upstream now. That verifies everything with sha256. It's quite complete because it's seeded from Quicklisp and had more packages added on (aswell as their native library dependcies.)

Nix isn't to everyone's taste but it demonstrates that you can treat security/reproducibility/etc as orthogonal to Quicklisp and Sourceforge (and to Lisp native tooling in general.)

> Last time I checked on it, QuickLisp doesn't support fetching packages over anything except for plain http, with no encryption and no verification mechanism in place to detect files that may have been tampered with during transmission.

I know it's not an excuse, but it was fun as heck booting up "capital M" MacOS (9.2.1) and loading Quicklisp into MCL without any trouble. I'm not even sure that's a supported platform by Quicklisp. https://code.google.com/archive/p/mcl/

I think there might have been bits and pieces somewhere to run Quicklisp on lisp machines... or at least ASDF, which is the core dependency
