July 2018 Quicklisp dist update now available

Hi everyone! There's a new Quicklisp update for July, and regular updates should resume on a monthly schedule.

I'm using a new release system that involves Docker for easier build server setup and management. It took a while to get going but it should (eventually) make it easier for others to run things in an environment similar to mine. For example, it has all the required foreign libraries needed to compile and load everything in Quicklisp.

Here's the info for the new update:

No May 2018 Quicklisp dist update

The computer on which I make Quicklisp builds stopped working a little while ago, and I haven't had time to dive in and work on it. As soon as it's fixed, I'll prepare and release a new dist. Sorry about the inconvenience!

There is some extra churn this month. It's mostly because of the failure of cl-curlex, a library that uses SBCL internals and which no longer works as of the latest SBCL. Many projects (all by the same author) depend on cl-curlex, and they all broke. There hasn't been any response to my bug report yet.

The other removals are due to author request, neglect, or other breakage. If you'd like to restore a removed project to Quicklisp, let me know - I'm happy to help.

To get this update, use (ql:update-dist "quicklisp").

Enjoy!

Quicklisp implementation stats for 2017+

Here are some raw HTTP request stats for each CL implementation supported by Quicklisp from 2017-01-01 onward. Each request corresponds roughly to downloading a single project.
  • SBCL: 4,518,774 requests
  • Clozure CL: 488,057 
  • CLISP: 34,767
  • LispWorks: 25,700
  • ABCL: 23,913 
  • Allegro: 19,501
  • ECL: 19,027
  • CLASP: 3,335
  • CMUCL: 965
  • MKCL: 79
  • Scieneer: 0
I gathered this info to check Scieneer activity levels to plan future support. Turns out nobody with Scieneer has used Quicklisp since 2013. Bummer!

Build failure RSS feeds

Every day, I build each project that Quicklisp tracks. If a project fails, I try to track down the author and let them know. If a project chronically fails and there's no fix in sight, I drop the project from Quicklisp.

In an effort to help authors follow build status, I've made a system of RSS feeds that are updated with daily build failures. The feeds have the following patterns:

Each feed entry has info about where Quicklisp gets the project, what systems are failing, and an excerpt from the build log and backtrace. There are links to the full build log. 

I hope you find these reports useful. If you have any suggestions or questions, feel free to get in touch.

The Quicklisp local-projects mechanism

Quicklisp provides a lot of software, but there’s also a simple way to load things that Quicklisp doesn’t provide. That same mechanism can be used to override libraries Quicklisp does provide.

The local projects mechanism sets up a special directory that is automatically scanned for software to load. Here are a few quick examples.

Trying a library not in Quicklisp

First, imagine that you just heard about a great new library and want to try it. However, it’s not available through Quicklisp yet, only through a git repository on https://example.com/fun-project.git. One easy way to try it:
$ cd ~/quicklisp/local-projects
$ git clone https://example.com/fun-project.git
After the git command completes, and there is a fun-project subdirectory with a fun-project/fun-project.asd file present, the system is visible to ASDF and can be loaded either with ql:quickload or asdf:find-system. When loaded through ql:quickload, Quicklisp will automatically fetch and load any prerequisites if needed.

Overriding a library in Quicklisp

Second, imagine that you want to hack on a library that Quicklisp already provides. You don’t want to load and hack on the version from Quicklisp - that software is not under version control, and just represents a snapshot of the project at a particular point in time.

Once again, the procedure is to put the software in the ~/quicklisp/local-projects/ directory:
$ cd ~/quicklisp/local-projects/
$ git clone https://github.com/xach/vecto.git
After the git command completes, (ql:quickload "vecto") will load the library from local-projects rather than from the standard Quicklisp release.

How it works

The local-projects mechanism is relatively automatic. Here’s how it works underneath, and how to fix problems that might crop up.

ASDF has an extensible mechansim (the asdf:*system-definition-search-functions* variable) for searching for system files. Quicklisp extends this mechanism with a function that does the following, all in the context of the local-projectsdirectory.
  1. If there is no file named system-index.txt, it is created by scanning the directory tree for system files (matching "*.asd"). Each pathname is added to the file.
  2. If the system-index.txt file exists, but its timestamp is older than its containing directory, the directory is rescanned and the index recreated.
  3. The system-index.txt is searched for any entry with a pathname-name that matches the desired system name. If there’s a match, matching pathname is probed. If it still exists, it is returned. If it has disappeared, the system-index.txt is recreated as in step 1 and the search is retried.
  4. Otherwise the system search is deferred to the remaining ASDF system search functions.
When there are multiple system files with the same name in the directory tree, the one with the shortest full pathname name is returned. In the case of a pathname length tie, the one that is #'string< is returned.

Timestamp problems can sometimes crop up with step 2 above. For example, if you have a directory local-projects/my-project/ and you create local-projects/my-project/supporting-system.asd, the timestamp of local-projects/ is not updated and supporting-system.asd won’t be automatically added to the system index file.

There are a couple ways to force an update of the system index file. Within Lisp, you can use (ql:register-local-projects) to immediately regenerate system-index.txt. Outside of Lisp, you can use the touch command (or an equivalent) to update the timestamp of the local-projects directory, which will trigger a rebuild of the index on the next attempt to find systems..

Because of how the system index file is created (and recreated as needed), Quicklisp must have write access to the local-projects directory to make use of it.

Configuration

The local-projects mechanism is configured through a special variable ql:*local-project-directories*. By default, it includes only the local-projects subdirectory in the Quicklisp install directory, but you can add or remove directories at any time to have more places scanned for systems.
To disable the local-projects mechanism entirely, set ql:*local-project-directories* to NIL.

Build failures with ASDF 3.3.1

SBCL 1.4.3 ships with ASDF 3.3.1, and a number of Quicklisp projects have build problems as a result. Linedit, mgl, micmac, cl-string-match, and others are affected.

Here is a build failure report for yesterday. (You can ignore the gendl failures - it's a special case.) If anyone has ways to fix these projects, please do so as soon as you can - otherwise they will be removed from the January Quicklisp dist update in a few weeks.
